Electriccar battery maintenance:

Since the lithium-ion (li-on) battery is the most important component in an electric vehicle, all maintenance efforts should start there.
Batteries have a limited lifespan, which can be extended through proper management and regular charging. And it’s worth noting that standard li-on batteries have a lengthy guarantee period. To preserve the health and lifetime of a lithium-ion battery, you should charge it to 90% capacity and then disconnect it immediately. Batteries can also lose charge when exposed to extremely low temperatures, so if feasible, store your vehicle in a moderately temperate location.
The unavoidable reality is that the longer you own an EV, the shorter its range will become. However, the time it takes for a battery to decline considerably surpasses the average ownership term of an EV. Replacement batteries are always a possibility, but tend to be costly.

Tyre maintenance:

Due to the weight of the batteries, which are placed horizontally on the floor of the car, EV tires are less prone to wear and tear than internal combustion automobile tires. Low tire strain can also reduce the variation of an electric-powered car by about 3%.

Brake maintenance:

Regenerative braking uses a vehicle’s electricmotor to slow it down. It helps to slow down the car when needed, reducing stress on the brakes and, consequently, reducing brake disc breakage and resulting in less brake dust.

Regenerative braking also enables the vehicle to recycle part of its kinetic energy by recharging the battery. It's estimated that EVs use their brakes 50% less than ordinary cars – helping to keep costs lower than those of an ICE or fuel-powered car.
