Vehicle electrification is the process of powering the vehicle by electricity, replacing vehicle components that operate on a conventional energy source with components that operate on electricity. In general, vehicle electrification is focused on the powertrain driven by electricity and its auxiliary systems such as on-board and off-board charging systems, as well as wireless power transfer. Vehicle electrification also covers many other aspects of vehicle functionalities that exist in a conventional non-electric vehicle, such as electronic power-assisted steering, electronic stability program, electronic traction control, intelligent light system, smart electromagnetic suspension, all-wheel drive, airbag deployment system, and more.
