Hyundai Tucson: 48V Battery System - Description

Hyundai Tucson - Fourth generation (NX4) - (2020-2023) - Workshop Manual / Engine Electrical System / 48V Battery System / 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.
