For an example, in a hybrid car, a radiator works to cool the combustion engine while a second radiator cools the power electronic system that runs the electric motor.
Because Nissan LEAF does not have an internal combustion engine, Nissan has incorporated an "Approaching Vehicle Sound for Pedestrians" system, which is designed to alert pedestrians that a vehicle is approaching.
The parallel full hybrid system developed by Porsche also offers "coasting" at higher speeds, a mode wherein the internal combustion engine is turned off and the electric motors use vehicle momentum to generate electricity that is stored in the lithium-ion battery.
