An electric drivetrain is a system that powers a vehicle using electricity instead of traditional fuels. It typically includes components like an electric motor, a battery pack, and a controller. The electric motor converts electrical energy into mechanical energy, allowing the vehicle to move. Electric drivetrains are known for their efficiency and lower emissions compared to internal combustion engines. They can be found in various vehicles, including electric cars, buses, and trucks. The use of electric drivetrains is growing as more manufacturers focus on sustainable transportation solutions.
