Hyundai Tucson: 48V Battery System - Description
Description
The Mild Hybrid Electric Vehicle (MHEV) uses hybrid power source (Engine, MHSG), so its fuel efficiency is relatively high and exhaust emission is very small compared to the traditional vehicle which uses only engine as power source. It consists of the engine, motor, 48V voltage battery and control modules.
In Engine supports the motor in case the vehicle needs more power (HEV Mode).
The Mild Hybrid Starter Generator (MHSG) not only drives the vehicle but also generates electric energy during regenerative braking for charging the 48 voltage battery.
