Electrification Level

Description

Electrification level defines to what level the vehicle is powered by electric system. The common electric system configurations are mild hybrid, strong hybrid, plug-in hybrid, battery electric, and fuel cell vehicles. (1) Mild hybrid is the system such as 12-volt start-stop or 48-volt belt integrator starter generator (BISG) system that uses an electric motor to add assisting power to the internal combustion engine. The system has features such as stop-start, power assist, and mild level of generative braking features. (2) Strong hybrid systems, in vehicles such as the Toyota Prius, mainly consist of motors, conventional gasoline engine, and battery, but the source of electrical charge for the battery power is provided by the conventional engine and/or regenerative braking. (3) Plug-in hybrid systems, in vehicles such as the Toyota Rav4 Prime, mainly consist of motors, conventional gasoline engine and battery. Plug-in hybrid vehicles are like strong hybrids, but they have a larger battery pack and can be charged with an external source of electricity by electric vehicle supply equipment (EVSE). (4) Battery electric vehicles (BEV), such as the Tesla Model S or Nissan Leaf, have only a battery and electrical motor components and use electricity as the only power source. (5) Fuel cell electric vehicles (FCEV) use full electric drive platforms but consume electricity generated by onboard fuel cells and hydrogen fuel.
