Over fifty percent of the expense for a new DC Fast Charger goes towards a singular safety circuit. Specialists indicate this might undergo changes in the future.
-
Building DC fast chargers can be extremely expensive.
-
Approximately 60% of the total expense goes towards a circuit specifically intended to protect individuals from electric shock during the charging process.
-
It might be possible to find a less expensive yet equally safe method to achieve this, which could also enhance the reliability of electric vehicle chargers.
Have you ever wondered why DC fast chargers are so costly to construct? A solitary 300-kilowatt Level 3 charger—that’s merely
one
Staying for an extended period at a public DC fast charger can exceed costs of over $100,000. This expense is among the factors contributing to the sluggish development of charging infrastructure and its heavy reliance on governmental funding.

.
Let’s discuss what’s contained within that charger. If we were to dismantle it, we’d discover approximately $90,000 worth of electronic components responsible for transferring power from the electrical grid to your vehicle’s battery. The surprising part? Around 60% of this expense covers a single safety circuit designed to ensure nothing malfunctions and causes harm to you. This indicates that over half the price of an electric vehicle charger is dedicated solely to safeguarding your well-being.

$54,000 in Shock Protection: Why It Matters
The system is referred to as an isolation link. As stated
IEEE Spectrum
The estimated cost for this protective measure is around $54,000. If you extrapolate that figure to cover an entire 8-stall charging station, over $430,000 would be allocated solely for safety gear. Here’s how it functions:
Fuel dispensers use mechanical mechanisms for controlling the flow of gas into vehicles. In contrast, electric vehicle charging stations handle high-voltage electrical currents.
frequently at 800 volts or higher
Electricity is lazy; it will take the easiest route to the ground. If something goes wrong with this immense force, it could electrocute you immediately. That’s precisely why safety measures are crucial.
An isolation link achieves a safety principle known as
galvanic isolation
This involves isolating two distinct circuits within an individual electrical setup to stop current from passing between them. For electric vehicle chargers, this entails disconnecting the electrical connection between the charger’s power supply and the vehicle. Therefore, should a malfunction happen, the energy will have no route except to return to the grid.
Here’s how
IEEE
explains it:
Assume an electric vehicle’s battery starts to leak. Since the leaked substance conducts electricity, it can create a pathway for electrical flow between the battery system and the vehicle frame. Should the grounding connection fail, and assuming there is no insulation, the car’s structure might become highly charged. Consequently, anyone who touches the automobile while grounded risks receiving a severe electric shock. However, with proper insulation, this danger vanishes as there won’t be any conducting route allowing electricity from the power grid to reach the car exterior.
In order to achieve electrical separation, each Direct Current Fast Charger incorporates a transformer within its power conversion equipment—this component transforms alternating current (AC) into direct current (DC), and vice versa. The high-frequency transformers used here can handle large amounts of electric power at elevated voltage levels, serving as an essential element in the circuit design without establishing a direct link from the utility grid to your vehicle. Although this setup is complex and costly, failing to include it might result in a charging error turning your Tesla into something akin to aTesla coil instead of safely replenishing its battery.
More Affordable Charging Options Are Not As Straightforward

Researchers and engineers know that charging infrastructure is too expensive. These experts are looking into ways to cut costs without compromising safety. But some of those ideas come with serious caveats and would mean rewriting how every modern EV charges.
One suggestion is to remove the isolation link from the charger and instead mandate that electric vehicles incorporate their own isolation system within the vehicle’s onboard charger. As onboard chargers in automobiles manage power conversion, they typically include galvanic isolation. Nevertheless, many of these systems generally support power conversion only at levels up to Level 2 charging speeds; Tesla being an exception, for instance.
can handle up to 48 amps in most of its versions
).
This might significantly reduce the expense of the chargers, yet all cars are not constructed identically.
Today’s electric vehicles come with various charging systems, and placing the burden on manufacturers would necessitate a new universal standard that currently does not exist. As such, earlier models of EVs might get excluded from this transition. Additionally, there’s the concern about relying on car makers to embrace and execute a novel universal standard securely. After all, experience has shown us that they are entirely consistent when it comes to regulating themselves without external oversight.
examining cases such as your observation of Volkswagen’s diesel emissions cheating, the General Motors ignition switch issue, and the Takata airbag recalls
).
Next comes the significant issue of expense. We shouldn’t overlook that the price tag for this circuit isn’t going away anytime soon. Relocating the hardware into the vehicle wouldn’t eliminate the cost; instead, it would merely shift the expense from the charging station to the car itself. To put it plainly, it’s unfeasible from the outset.
The Argument for Abandoning Solitude

This completes the cycle: safety features render DC fast chargers extremely costly. High expenses result in delayed installations and restrict the quantity of charging spots at each location. Regarding solutions, some specialists advocate eliminating isolation connectors in charging stations entirely.
Initially, this concept may appear risky. However, IEEE proposes a different approach: rather than separating the circuits, why not incorporate an additional grounding system? Consider this: the secondary ground wouldn’t just provide another fail-safe; it could also identify a grounded fault immediately and halt the charging process right away upon detection. In principle, this solution could remove the necessity for expensive isolation components. Furthermore, it would enhance the charger’s dependability considerably since it streamlines the charger’s power electronics by removing one significant potential source of malfunction.
Next is another concern that needs addressing: discrepancies in voltage levels.
If the line voltage from the charger surpasses that of the vehicle’s battery momentarily, an unchecked flow of current might lead to damage of the vehicle components. According to IEEE, addressing this issue involves employing a buck regulator—a device designed to reduce voltage levels safely from the power supply. However, the piece notes that although this introduces additional intricacy into the charging setup, incorporating such a buck regulator with comparable capacity would only increase costs by roughly 10%, as opposed to utilizing an isolation link.
Will This Actually Happen?
Perhaps, but definitely not in the near future.
The rationale for eliminating galvanic isolation appears logical on paper.
original Tesla Roadster
used non-galvanically isolated charging,
but
It also lacked the ability to utilize DC Fast Charging. Contemporary DC fast chargers deliver substantial currents into today’s electric vehicles’ batteries and necessitate additional safety features (thus requiring an isolation link). However, if—and this is a significant condition—
if
—The industry not only has the potential to create a dependable and secure method for achieving this, but it could also revolutionize the electric vehicle charging sector.
Through a pragmatic perspective, the global community is currently grappling with providing adequate public charging solutions, and no one wishes to be the pioneer taking risks regarding safety. Companies specializing in charging infrastructure, automotive manufacturers, along with regulatory bodies would require an ironclad assurance that any non-isolated system matches the current standards of charger safety. Assuming this condition were met, implementing these changes could still take several years—particularly considering how critical safety concerns must be addressed thoroughly.
For now, anticipate that new electric vehicle chargers will continue to be quite expensive. Since when it comes to ensuring your safety from electrical hazards, the industry has not been keen on compromising (at least not yet).

Unlike typical electric vehicle conversions that use repurposed Tesla drivetrains, this particular conversion relies solely on after-market components.
-
In the early 1990s, a Ford Mustang Foxbody had its engine swapped out for an electric motor but kept its original five-speed manual transmission.
-
It has become more than double the power it initially had, and unlike many electric vehicle conversions, this one is also slightly lighter.
-
For this electric vehicle conversion, only brand-new after-market components were utilized, hence there isn’t a refurbished Tesla engine beneath its hood.
Modifying vintage automobiles to operate on electric power is a sensitive subject among traditionalists who prefer these vehicles to maintain their authentic internal combustion engines. However, although you might not endorse every conversion of classic cars into electrics, certain transformations prove to be more sensible than others, as seen in this early example.
1990s Fox-body Ford Mustang
might be one of them.
The designation pertains to the third-generation Mustang constructed using what’s known as the “Fox platform.” This architecture supported over a dozen rear-wheel-drive vehicles from Ford, Lincoln, and Mercury. The Mustang associated with this generation first appeared in 1978 and stayed in production up until 1993. It significantly surpassed the popularity of its predecessor—the smaller and less powerful second-generation model.
However, like many performance cars of that time, it would not meet contemporary speed standards. Without the 5.0-liter V8 or the 2.3-liter four-cylinder turbo installed in your Fox Mustang, achieving 0 to 60 mph probably took more than 10 seconds. Even so,
the V8
required approximately 7.5 seconds to accelerate the car to 60 mph, but this decreased to about six seconds after the introduction of electronic fuel injection increased the engine’s output to 225 horsepower.
![]()
Perhaps that’s why the fact that the low-mileage, single-owner Mustang was converted to electric power by FuelTech in Georgia doesn’t seem like such a major issue.
The main aspects of this specific transformation are highlighted in a video posted by
The Racing Channel
The car comes with the original manual transmission, something you wouldn’t need in an electric vehicle. However, it enhances the driving experience without adding extra weight compared to the standard model.
Even though in an
EV conversion
When you remove the bulky engine, you typically end up making the vehicle heavier by adding batteries. However, this particular conversion is about 50 pounds lighter than the standard model, which is quite remarkable. With 500 horsepower and more than 700 pound-feet of torque, it ought to accelerate as swiftly as a spacecraft.
The current transmission might not survive under such high torque since it wasn’t built for that kind of power, yet the constructors intend to maintain a manual setup. Thus, they’ll most likely replace it with a new gearbox once it inevitably gives out.
The weight distribution across the two axles was maintained evenly by dividing the battery pack (with an undisclosed capacity). Approximately half of it is positioned beneath the hood, near the drivetrain, inverter, and various electronic components, with the remaining portion located at the rear.
During their drives, the most peculiar aspect of operating this vehicle involves changing gears. The process mirrors what one would experience with a conventional internal combustion engine car, complete with audible changes in the motor’s revolutions per minute and subtle vibrations from the clutch engagement. Personally, were I behind the wheel, I might rely heavily on the clutch simply due to the tactile feedback available. This feature likely surpasses systems found in certain vehicles that simulate gear shifts and engine sounds artificially.
While EVs don’t need
a manual transmission
since they have a lot of torque from virtually zero RPM, having one with cogs that you can swap is more engaging for a keen driver. When you don’t want to go through the gears, you can simply leave it in second or third, as it has more than enough torque to get the car off the line without you having to start in first.
The most impressive aspect is that you don’t need to use the clutch to separate the motor from the transmission because the electric motor’s revolutions per minute drop to zero upon stopping. We believe there’s significant potential for such modifications, particularly as this approach allows you to retain the original transmission, driveshaft, differential, axles, and all standard suspension parts, making it the simplest method of conversion available.

Tom Moloughney repairs a homeowner’s damaged plug and describes the issue that caused it.
It goes without saying that most electric vehicle charging happens
takes place at home
It is not a secret that
Not every Level 2 charger is made alike.
However, even though L2 installations are typically viewed as simple, they too can vary greatly. These enclosures handle significant electrical currents. Any deficiency could lead to severe outcomes.
To reinforce that idea, our colleague Tom Moloughney initiated a segment on his own.
State of Charge
The YouTube channel is named Recharge Rescue. Briefly put, they go to visit individuals who have issues with their residential charging stations. He elucidates the problem before bringing in an accredited electrician with expertise in electric vehicles to fix the situation.
His series began last year, however, the newest addition transports us to Ohio for a
Mustang Mach-E
owner with a damaged NEMA 14-50 receptacle.
![]()
The video kicks off with crucial information: not every outlet marketed as industrial-grade can handle prolonged high-power usage. Moloughney points out a Leviton 279-S00 plug, usually priced at about $10 and labeled as industrial quality. He contrasts this with a newer Leviton model made exclusively for electric vehicle charging. Significant distinctions emerge; the enhanced plug is noticeably bulkier, featuring additional internal metal components and superior terminal connections within its casing.
The cost discrepancy is significant—at $66 compared to $10. However, Moloughney points out that the elevated price is entirely justified due to the enhanced quality and functionality. To sum up, you invest more to receive more.
When visiting the Mach-E owner, we observed that the melted NEMA plug was actually a smaller, inferior model. Fortunately for them, a significant fire did not break out. The outlet had become sufficiently heated to permanently affix the charger’s plug. Moloughney provided a replacement charger and, working alongside a skilled electrician, they decided to eliminate the old outlet entirely in favor of direct hardwiring. Additionally, the breaker panel was upgraded to include a 50-amp breaker; it turned out that the earlier electrical work utilized a 60-amp breaker paired with 6-gauge Romex wire to supply power to what should have been a 50-amp outlet. To prevent overloading the circuit, the new charger was rated down to handle up to 40 amps.
The upgrade proceeds without issues, however, the key message from the video is to avoid cutting corners during your home setup. Typically, hardwiring is preferable; nonetheless, if you choose to use a plug, ensure it’s not only industrially rated but also designed to manage prolonged power needs for EV charging. Additionally, it’s most advisable to have a certified electrician who has expertise inEV installations carry out the work.

How to Select a Residential Charging Station for Your Electric Vehicle
oleh admin | Feb 28, 2025 | battery charging, electric cars, electric power, electric vehicle charging stations, transportation
Using an electric vehicle, you might find that a simple wall socket becomes your greatest ally. I discovered this during my journey with the Rivian R1T.
Let’s be real for a second: nobody wants to sit around and wait hours and hours for their electric vehicle to charge. The fear of long charging times, along with nowhere to actually do it, is what scares many people away from owning an EV. And certainly, the time it takes to charge from a standard wall outlet—which might take
anywhere from 60 to 200 hours
depending on the car—isn’t very encouraging.
Many electric vehicle (EV) owners connect their cars at home and utilize quicker Level 2 chargers to power up within hours instead of days. Some depend on public DC fast charging stations either routinely or during vacations to refill in just minutes. Nonetheless, every EV is capable of being plugged into an ordinary 120-volt household socket as well. However, how practical is this option truly?
It’s actually very good, believe it or not. I found this out during my road trip
out to the far West Texas desert in a 2025 Rivian R1T
. That experience convinced me that so-called Level 1 charging, the slowest form of EV charging there is, can be an immensely useful tool—if you use it correctly.
Actually, using wall chargers really came to my rescue during this trip. Here’s why.
(
Full Disclosure:
Rivian lent me an R1T for a journey during the 2024 winter break.
Over the holidays, I drove about 400 miles from San Antonio to the remote town of Marfa, Texas near the Mexican border. As you might guess, there aren’t many EV charging options out that way. One hotel near the house where I was staying had a Level 2 charger, but it was for guests only and I wasn’t staying there. I probably could’ve talked my way into borrowing it a few times, but didn’t want to take advantage.
Photo by: Patrick George
No, I don’t normally park like this. But there was nobody around.
My best bet was a Tesla Supercharger station in the town of Alpine, which I used quite often on this trip thanks to the adapter Rivian included. But that was 30 miles away before any highway range losses, and in the
opposite
The direction towards everything I love doing outside in Marfa. To summarize, once I left the parking area, success came rather quickly.
Luckily for me, Rivian also included a portable wall charger. I decided to throw the R1T on that when it was parked in the driveway. Lo and behold, it was just what I needed.
Stage 1 Charging: What You Need to Know
A typical 120-volt household electrical socket usually delivers between 1 to 2 kilowatts (kW) of power, which equates to approximately three to five miles of range added per hour.
With a 149-kilowatt-hour battery pack (of which 140 kilowatt-hours are usable), similar to the one in my R1T Dual Motor Max Pack test unit, you would expect
around 30 to 40 hours to charge from 20% to 80% capacity
, depending on the speed. Around 2 kilowatts of electricity for each kilowatt-hour of battery capacity, best-case scenario. Makes sense, right?
That’s a lot less than my own home ChargePoint Level 2 charger, which runs a steady output of 7.2 kW. That means it can charge my Kia EV6, with its 77.4 kWh battery, from 0% to 100% in around 10 hours, though my typical time is around five or six hours. I’ve never run that car all the way down to 0%, and I don’t intend to ever do that.
Photo by: Patrick George
So if you’re new to EVs, you may scoff at Level 1 wall charging as being too slow. But remember this: What is your car doing most of the time? Well, it’s just sitting there parked.
Since it’s just sitting there, that means you can “refuel” it. This is a kind of secret superpower for EVs that few people talk about. With a gas-powered car, you have to drive somewhere and get gas. With an EV,
for 95% of the time when the car is stationary
, it can continue charging its battery as long as it’s close to a power source.
Photo by: Patrick George
This proved to be highly beneficial for me. During my journey, I didn’t spend every moment behind the wheel. Instead, I spent time exploring the city on foot, visiting landmarks, dining and imbibing with loved ones, or snapping pictures. Just like how any car would sit idle during the day, so did the R1T most of the time. Hence, I thought why not leave it plugged in when it wasn’t being used.
It turned out very rewarding. Simply by plugging into the wall socket, I managed to gain an additional 30 to 40 miles of range each day, with much of this happening during nighttime hours while I slept. Since I never let the Rivian’s battery dip all the way to zero percent, I avoided having to recharge from empty. Additionally, I could rely on residual charge left over from using the Tesla Supercharger. As such, connecting to the standard wall outlet guaranteed ample range for handling my everyday tasks and trips.
I’ve noticed that electric vehicle (EV) charging isn’t usually an “it’s depleted, so I should refill immediately” scenario as with gasoline vehicles. Instead, it’s all about ensuring you get just enough charge for your specific needs each time. I didn’t require the R1T to be fully charged daily; rather, I only needed sufficient range to meet my regular travel requirements. Charging via the wall outlet provided ample everyday coverage until I could reach a Tesla Supercharger station again. Owning an EV makes one think more deliberately about managing power consumption. This shift in mindset can actually be quite beneficial.
That extra 30 to 40 miles from daily wall charging powered a lot of my trip. It’s why there’s also a not-insignificant number of EV owners out there who only use Level 1 wall charging for the job.
My colleague Kevin Williams has written about this extensively
; he’s an apartment-dweller and uses slower charging with great frequency.
Consider individuals who possess a compact electric vehicle equipped with a less sizable battery, or those who use an electric vehicle as their secondary or tertiary mode of transportation mainly for local trips and errands within the city. Why might they
not
Why use a wall outlet, particularly when you don’t require something as quick or expensive as a Level 2 home charger?
For me personally, I find that using a Level 2 charger is essential because I drive quite often at home. Depending only on Level 1 charging doesn’t meet my requirements effectively. However, nowadays, I view this Level 2 charger more like an additional resource—an extremely handy one—for situations such as long drives and holidays. Especially when traveling to unfamiliar locations where high-speed charging stations might be sparse, I’d highly suggest packing a portable wall charger. Although it’s not the quickest solution available, having it beats being without power altogether and can prevent serious issues.
I’ll include the usual warnings here and emphasize that it’s crucial to ensure the electrical setup you’re drawing power from is safe.
is secure, contemporary, sturdy and capable of managing the workload
. If you’re leasing an Airbnb, make sure to confirm with the hosts whether they allow EV charging (and
It likely won’t make a significant impact on their electricity bill.
.)
Several manufacturers suggest avoiding the use of an extension cord for such purposes. When dealing with prolonged usage involving significant power draw, extension cords can pose issues. Although an industrial-strength, thick-gauge extension cord might work better in these scenarios, my advice remains consistent: follow exactly what your user’s guide recommends—alternatively, consult an electrician if you’re unsure about safely extending cables over greater lengths. Never presume that simply plugging in any available extension cord is safe. Certainly, level one charging aids in keeping vehicles operational; however, damaging chargers or causing fires could complicate matters significantly rather than solve them.
So long as you can do it safely, do not rule out Level 1 wall charging, especially on your next EV road trip. Always remember: if it’s parked, maybe it can be plugged in somewhere.

The Rivian R1T’s Gear Tunnel Is What Has Me Enthusiastic About Electric Vehicles

Maintaining an electric vehicle is straightforward. It involves significantly fewer tasks compared to maintaining a gasoline-powered car.
Although electric cars might have a higher upfront cost compared to traditionally fueled ones, they tend to be less expensive to operate through inexpensive at-home charging. Additionally, electric vehicles also
help their owners save money consistently through reduced long-term maintenance expenses
.
This is due to the fact that electric vehicles remove more than two dozen moving parts typically needing regular maintenance. As a result, an EV owner can avoid expenses related to tune-ups, oil changes, coolant system flushing, transmission services, and replacements of items such as the air filter, spark plugs, and drive belts. According to sources, this makes owning an electric vehicle cost-effective.

What Is the Optimal Electric Vehicle Service Timeline?
Nevertheless, an electric vehicle still demands some level of maintenance. Every manufacturer insists that owners adhere to a specific routine of inspections and servicing to maintain the integrity of their vehicle’s warranty. Failing to stick with this suggested plan could result in repair costs being out-of-pocket if issues arise.
Apart from rotating the tires, swapping out the cabin air filter and wiper blades, as well as refilling the washer fluid, most of this involves different mechanical checks. Car manufacturers recommend—and rightly so—that apart from straightforward chores such as verifying the tire pressure, replenishing the windshield washing fluid, and possibly switching the wiper blades, these processes ought to be carried out by an experienced professional at the dealership’s service center.
Three Distinct Electric Vehicles With Three Unique Service Timelines
To illustrate what usually tends to be necessary, let’s examine the upkeep timetable for the 2019 Chevrolet Bolt EV:
Monthly (performed by owner):
-
Verify the tire pressure and make adjustments if needed. Inspect the tires for excessive wear. Ensure the windshield washer fluid level is adequate and top up if required.
Every 7,500 miles:
-
Rotate the tires. Verify the coolant levels for the battery, cabin heater, and power inverter, as well as the accessory power and charger modules. Look for any visible fluid leaks. Examine the brake system. Conduct a visual inspection of the steering, suspension, and chassis parts for any damage. Assess the condition of the power steering, half-shafts, and driveshafts for excess wear, leakage, or harm. Test the operation of the restraint (airbag) system. Apply lubrication to vehicle body elements such as door locks. Ensure the accelerator pedal shows no signs of damage, stiffness, or obstruction; replacement should be considered if needed. Perform a thorough visual examination of the gas struts (part of the suspension), looking out for indications of wear, fractures, or similar issues. Confirm whether the tire sealant has expired—if installed—since this product is designed to patch up punctured tires until they can be permanently fixed.
Twice a year:
-
Wash away corrosive substances like road salt from the underbody with just water.
Every 15,000 miles:
-
Change the windshield wipers.
Every 36,000 miles:
-
Change the cabin air filter at regular intervals, replacing it more often if needed.
Every 75,000 miles:
-
Swap out the hood and/or body lift support gas struts.
Every five years:
-
Empty and refill the car’s cooling system. Change out the brake fluid.
Every seven years:
-
Get the air conditioning desiccant replaced. (This component absorbs and retains moisture within a vehicle’s AC system to help avoid rust and corrosion.)
Nissan provides two distinct maintenance schedules for the Leaf. The first schedule applies under more demanding driving conditions such as regular short journeys shorter than five miles during mild weather or ten miles when it’s below freezing, stop-and-go traffic in warm climates, prolonged slow-speed travel, operation in dusty environments, navigating rough, muddy, or salty roadways, or mounting a roof rack.
Schedule 2 demands less frequent upkeep but is applicable solely for highway travel under mild weather conditions. In essence, the majority of Leaf owners will find themselves needing Schedule 1 servicing.
Similar to the Bolt, this involves various routine maintenance checks. According to Nissan, these tasks include rotating the tires every six months or 7,500 miles and replacing the cabin air filter annually or every 15,000 miles. Furthermore, the brake fluid needs to be refreshed every two years or 30,000 miles, and the coolant should be replaced after 15 years or 120,000 miles.
Tesla suggests the following maintenance tasks and their respective frequencies:
-
Check the condition of brake fluid every 4 years (and replace as needed).
-
Replace the A/C desiccant bags every four years.
-
Replace the cabin air filter every two years.
-
Replace the HEPA filter every three years.
-
Service and grease the brake calipers annually or after 12,500 miles (20,000 km), particularly if you live somewhere with salty road conditions during colder months.
-
Rotate your tires every 6,250 miles (10,000 km), or sooner if the tread depth discrepancy reaches 2/32 inch (1.5 mm).
Frequent heavy braking from towing, descending mountains, or aggressive driving—particularly in hot and humid conditions—may require more regular inspections and changes of the brake fluid.
Moreover, Tesla includes these two points:
-
Battery coolant: Under typical conditions, you do not need to replace the battery coolant during the lifespan of your vehicle.
-
Brake fluid: Do not add more brake fluid.

Does Rapid Charging Damage an EV’s Battery?
Battery Pack
When considering an electric vehicle, the most expensive part to keep in mind is undoubtedly its battery pack. Over time, all electric car batteries tend to deteriorate and hold less charge, although this process occurs slowly. This concern was more significant with earlier EV models that struggled to reach even 80 miles per charge compared to modern vehicles capable of going over 300 miles. However, very few electric cars produced so far have experienced such severe degradation that their battery packs required replacement. Nonetheless, owning an EV for a sufficient period means witnessing a gradual decrease in driving range. If this reduction becomes inconveniently large, you might find yourself needing to replace the battery pack or upgrade to a newer model altogether.
Conclusion
Reduced upkeep doesn’t make an electric vehicle indestructible. Eventually, EV owners will likely need to change the tires, get the brakes fixed, and possibly replace parts like the steering and suspension components, hoses, headlights, tail lights, among others. Make sure to check your owner’s manual for detailed maintenance requirements tailored specifically for your electric car.
