What You'll Learn
No engine, fewer moving parts, fewer fluids
Electric vehicles (EVs) have no internal combustion engine, which means there are fewer moving parts and fluids. This results in less routine maintenance when compared to traditional cars.
Firstly, let's talk about the absence of an engine. The internal combustion engine is a complex piece of machinery with many moving parts that require regular maintenance and are prone to wear and tear. On the other hand, EVs have a battery, motor, and associated electronics that require little to no regular maintenance. The simplicity of the electric motor and its closed system design contribute to its reliability and reduced need for maintenance.
Now, let's discuss the reduction in moving parts. In a traditional car, the engine has numerous moving components, such as pistons, valves, and crankshafts, which require regular checks and lubrication. EVs, by contrast, have far fewer moving parts. This simplicity reduces the need for maintenance and also contributes to the overall reliability of the vehicle.
Fewer fluids is another advantage of EVs. Traditional cars require regular maintenance and fluid changes, including engine oil, coolant, brake fluid, and transmission fluid. In contrast, EVs do not require engine oil changes and often have sealed cooling systems that do not need regular maintenance. While EVs still require some fluids, such as brake fluid and windshield wiper fluid, the frequency of maintenance for these fluids is typically lower.
It is worth noting that while EVs may require less frequent maintenance, some routine tasks are similar to those of traditional cars. For example, brake fluid checks and tire rotations are recommended at regular intervals for EVs, just as they are for conventional vehicles. Additionally, EVs may require battery maintenance or replacement, which can be costly.
In summary, the absence of an engine, the reduction in moving parts, and the fewer fluids required contribute to the overall reduction in maintenance needs for EVs when compared to traditional cars. However, it is important to remember that EVs are not maintenance-free and still require some routine care and attention.

Less brake wear
Electric vehicles (EVs) tend to require less maintenance than conventional cars, saving an estimated $4,600 over the life of the vehicle. One of the main reasons for this is reduced brake wear.
Firstly, EVs have regenerative braking systems, which convert the energy used to brake into electricity to power the EV's motor. This means that less energy is required from the brakes themselves, reducing brake wear.
Secondly, EVs have a lower centre of gravity than conventional vehicles, making them more stable and less likely to roll over. This increased stability also contributes to reduced brake wear, as the brakes are under less stress.
Additionally, EVs have fewer moving parts than conventional cars, which means there are fewer components to maintain and less strain on the braking system.
However, it is important to note that EVs still require some brake maintenance. For example, the brake fluid and brake calipers may need to be cleaned and lubricated periodically. Overall, while EVs may experience less brake wear than conventional cars, regular maintenance and servicing are still necessary to ensure the continued reliability and efficiency of the vehicle.

No oil changes
One of the most significant differences between electric vehicles (EVs) and traditional internal combustion engine vehicles is the lack of required oil changes in EVs. This is because electric vehicles do not have an internal combustion engine that requires regular oil changes for lubrication and cooling.
The absence of an internal combustion engine in electric vehicles means there are fewer moving parts and fluids, resulting in reduced maintenance requirements. Without the need for oil changes, electric vehicle owners can save time and money on maintenance costs. This contributes to the overall lower maintenance of electric vehicles compared to conventional cars.
However, it is important to note that electric vehicles are not entirely maintenance-free. While they may not require oil changes, they still need to be serviced and maintained to ensure optimal performance and longevity. For example, electric vehicle owners should be aware of the specific maintenance requirements of their EV tyres, which may need to be rotated and replaced more frequently than those on conventional cars due to the increased weight of the specialised battery.
Additionally, other components of electric vehicles, such as the cabin air filters, brake fluid, and windshield wiper blades and fluid, may require regular attention and replacement. It is recommended to refer to the owner's manual for specific maintenance guidelines, as some tasks may be more discretionary based on usage and driving conditions.
Overall, the elimination of oil changes in electric vehicles is a significant advantage, reducing both the frequency and cost of maintenance compared to traditional internal combustion engine vehicles.

Battery replacement
Electric vehicles (EVs) typically require less maintenance than conventional vehicles. This is because the battery, motor, and associated electronics require little to no regular maintenance, there are fewer fluids that require maintenance, and there are fewer moving parts. However, one aspect of maintenance for EVs that requires consideration is battery replacement.
It is worth noting that battery replacement is a rare occurrence, as EV batteries are built to last and can often outlast the car itself. Proper battery care can also extend the life of the battery, delaying the need for replacement. This includes avoiding extreme battery levels, limiting DC fast charging, maintaining battery temperature, and using seasonal tires.
The cost of battery replacement can vary depending on the make and model of the car. For example, replacing the battery in a Toyota Prius may cost around $2,700, while replacing the battery in a Tesla Model S sedan or Ford F-150 Lightning pickup truck could cost tens of thousands of dollars. Additionally, labor costs for battery replacement can be significant, ranging from several hundred to several thousand dollars.
When considering battery replacement, it is important to weigh the costs and benefits. For older vehicles, the cost of battery replacement may outweigh the value of the car. However, for newer vehicles, the improved efficiency of solid-state batteries may make replacement a more attractive option. In some cases, third-party batteries may be available at a lower cost, but these may not offer the same performance or reliability as original equipment manufacturer (OEM) batteries.

Tire rotation and replacement
Electric vehicles (EVs) generally require less maintenance than conventional vehicles. This is because the battery, motor, and associated electronics require little to no regular maintenance, there are fewer fluids that require maintenance, and there are fewer moving parts. However, this does not mean that EVs are maintenance-free.
Tire maintenance is an important part of EV ownership. Unlike fuel-burning engines that need regular oil changes, the long maintenance intervals of EVs mean that tire maintenance is often overlooked. However, failing to pay attention to your EV's tires could result in reduced range, increased wear, or even tire failure that could lead to a crash.
EVs tend to wear out tires faster than gasoline cars. This is because EVs are heavier than their gasoline counterparts, and their tires experience higher wear rates. To prevent uneven tire wear and extend the life of your tires, it is important to rotate your tires regularly. Tire rotation involves moving the tires from one axle to the other, which changes the driving pressure and load they carry, ensuring that all four tires wear evenly. While the general recommendation is to rotate tires every 5,000 miles, EV owners should follow the manufacturer's recommendations, which may vary. For example, Tesla recommends rotating tires every 6,250 miles or if the tread depth difference is 2/32 inches or greater.
In addition to tire rotation, it is crucial to regularly inspect your tires and check the tread depth and air pressure. The minimum tread depth generally recognized as safe to drive is 2/32 of an inch. To check this, you can use the penny test by inserting a penny into a groove in the tire's tread with Lincoln's head pointed downward. If you can see all of Lincoln's head, it's time to replace your tire. It is also important to keep your EV's tires properly inflated to reduce noise, optimize battery range, and prevent uneven wear.
