What You'll Learn
Electric vehicles require less maintenance than their internal-combustion counterparts
Electric vehicles (EVs) generally require less maintenance than their internal-combustion counterparts. This is mainly due to the fact that electric motors have far
However, it is important to note that EVs still require regular maintenance and service. Some tasks are similar to those required for conventional vehicles, such as rotating the tires, replacing various fluids, and changing cabin air filters. Additionally, EVs have some unique maintenance requirements, such as the need for specialised tires that can handle the increased performance and additional weight of these high-tech vehicles.
One of the most critical components of an EV is its battery pack, which can be costly to replace. To extend the life of the battery, it is recommended to avoid extreme temperatures, frequent fast charging, and fully charging or depleting the battery. The coolant system is another important aspect of EV maintenance, as it is responsible for keeping the powertrain components cool. Periodic checks and services are necessary to ensure the system runs smoothly and prevent overheating.
While EVs do require less maintenance than internal-combustion vehicles, they are still complex machines that require regular care. Some maintenance tasks can be performed by trained technicians, while others may be recommended by the manufacturer to keep the vehicle warranty valid. Overall, the maintenance schedule for an electric car is much simpler and less expensive than that of a traditional gas-powered car.

Electric vehicles require specialised tires
Electric vehicles (EVs) require specialised tires to handle their increased performance and additional weight. The tires of hybrid and electric vehicles have to bear more weight due to the heavy batteries installed in them. This is a significant difference from vehicles with combustion engines, where a full fuel tank is significantly lighter than a battery pack.
EVs have instant torque, meaning they accelerate immediately when you press the pedal. This high instant torque can increase wear and tear on tires, so EV tires need good grip and low rolling resistance. Rolling resistance refers to the friction when a tire rotates, and it directly impacts the range a vehicle can travel. EV tires with low rolling resistance offer a smoother, more energy-efficient, and low-impact ride.
To increase EV tire longevity, maintenance is crucial. EV owners should regularly check their tire pressure and adjust it if necessary. Properly inflated tires provide better mileage. It is also important to rotate the tires and inspect them for wear. Depending on how the tire tread is wearing, a wheel alignment may be necessary.
Some tire manufacturers have developed innovative solutions to meet the unique requirements of electric vehicles. For example, Continental's EcoContact™ 6 addresses the increased weight of EVs and hybrids by offering low rolling resistance, high grip, and sturdiness. Their ContiSilent technology uses a foam layer inside the tire to reduce road noise, a feature especially important for EVs as their quiet engines don't mask tire noise like in traditional cars.

Electric vehicles require regular brake fluid changes
Electric vehicles (EVs) require far less maintenance than cars with internal combustion engines. This is because they have fewer moving parts, no oil to change, and no fuel, water, or radiator pumps to go bad. However, there are still several services that EV owners need to stay on top of to ensure their vehicle functions optimally. One of these services is regular brake fluid changes.
Brake fluid is vital in any vehicle, including EVs, as it is the connection between the brake pedal and the calipers that press the brake pads against the wheel discs. Without the proper level of fluid, or if the fluid is of the wrong type, or if it is overdue for a change, the braking system can be severely compromised. Most modern braking systems rely on hydraulics, and the fluid is essential to this system.
EVs use regenerative braking technology, which places additional demands on the brake fluid. This technology allows the motor to slow the vehicle by recovering its kinetic energy and subsequently feeding that energy back into the battery pack. This means that the mechanical brakes are used less frequently, which, in turn, puts less wear on the brake pads and rotors. However, it also means that there are fewer chances for a technician to inspect the system and correct potential issues.
As brake fluid ages, it can become contaminated with water, and corrosion becomes an increasing concern. Additionally, the various electrical currents within a vehicle can come into close proximity to brake hydraulics, which can damage system components. For these reasons, it is recommended to use a brake fluid that is specifically designed for regenerative braking systems, such as FERODO DOT 5.1 EHV brake fluid. This type of fluid is less conductive than other fluid types, helping to protect system components.
It is important to note that the replacement times for brake fluid can vary between different vehicles and manufacturers. For example, Ford recommends replacing the brake fluid in the Mach-E and Lightning every three years, while Tesla suggests checking the fluid every two years. Therefore, it is always best to consult the owner's manual or a qualified technician to determine the recommended maintenance schedule for your specific EV model.

Electric vehicle batteries degrade over time
Electric vehicles (EVs) are known to require less maintenance than their internal-combustion counterparts, but they still require servicing. EVs do not require services like oil changes, transmission and differential servicing, or cooling system flushes. However, they do need regular maintenance, including rotating the tires, replacing fluids, and changing cabin air filters.
One crucial component of EVs that requires attention is the battery pack. Battery packs in EVs are designed to last the lifetime of the vehicle, but they can degrade over time. This degradation is primarily due to the use of lithium-ion cells, which start depleting as soon as they are created. As a battery goes through charge cycles, it gradually loses its maximum potential, a process known as cycling ageing. The state of health (SoH) of a battery is a measure of its lifetime capacity, and when an EV battery's SoH falls to 70%, it is considered to be at the end of its life.
There are several factors that influence battery degradation. One key factor is temperature; extreme temperatures over long periods can accelerate degradation, so it is recommended to keep EVs within an optimal temperature range of 50–86 degrees Fahrenheit. Additionally, frequent fast charging can degrade the battery more than Level 2 charging, so it is advisable to maintain a charge between 60% and 80% and avoid continuous charging.
While battery degradation is inevitable, it is not necessarily a cause for concern. Modern EV batteries often last more than 10 years, and some manufacturers offer warranties of 8 years or 100,000 miles, with predictions that batteries could last up to 500,000 miles. Furthermore, advancements in lithium-ion technology will lead to slower degradation rates and improved battery lifespans.

Electric vehicles require less maintenance than hybrid vehicles
Electric vehicles (EVs) generally require less maintenance than hybrid vehicles. This is because EVs have fewer moving parts than hybrid or internal-combustion engines. For example, EVs do not require services like oil changes, cooling system flushes, spark plugs, drive belts, transmission and differential servicing. There is also no fuel pump, water pump, radiator, or engine gaskets to maintain or replace.
EVs also have regenerative braking systems, which use the kinetic energy from the car under braking to charge the vehicle's battery. This reduces brake wear and means that EVs tend to use their mechanical brakes less frequently, resulting in less wear and tear on brake pads and rotors.
However, it is important to note that EVs are still complex machines that require regular service and maintenance. Some of the maintenance tasks specific to EVs include rotating the tires, replacing various fluids, and changing cabin air filters. EV owners should also be mindful of the battery pack, which is the costliest component to replace. While manufacturers offer warranties on battery components, typically ranging from 8 to 10 years, extreme temperatures can negatively affect the battery, and fast chargers can degrade the battery faster than Level 2 charging.
In contrast, hybrid vehicles have both an internal combustion engine and an electric motor, resulting in more parts, complexity, and electronics. This can make repairs more complicated and expensive, especially once the vehicle ages out of warranty. Additionally, hybrid systems add specialized components that may require more skilled technicians and time to repair.
Overall, while EVs may require less maintenance than hybrids, both types of vehicles necessitate regular service and upkeep to ensure optimal performance and longevity.
