Maintenance Cost Savings
Unlike the engine and transmission in a conventional vehicle, the electrical powertrain components of an EV are essentially maintenance free. Even in PHEVs and EREVs, which still have an internal combustion engine, the engine operates less frequently so oil change intervals can be extended. Finally, all modern EVs use regenerative braking to recapture electrical energy as the car is brought to a stop. Because this process greatly reduces the load on the normal braking system, routine wear items like brake pads and shoes will require replacement at much less frequent intervals.
