Panasonic develops 12V NiMH energy recovery system for start-stop vehicles; aims to double fuel economy improvement rate of start-stop systems

Green Car Congress

This system allows the energy generated during braking to be stored in the batteries and use the stored energy to power the vehicle’s electrical components, thus ensuring power availability even when the engine is not being used. The system is also designed to supply power to the drive assist motor, improving fuel economy.
