Hyundai Ioniq (AE) 2017-2025 Service Manual / Hybrid Motor System / Hybrid Motor Assembly / Description and operation

Description

Hybrid motor system is equipped with two electric motors.

These motors include the drive motor and the HSG that plays the role of starter motor and alternator (generator).

The drive motor moves the vehicle, reduces the noise, vibration and harshness (NVH), and improves fuel efficiency.

The drive motor supplements the engine power when the driver press the accelerator pedal or when the vehicle is running in the fuel efficiency mode.

In addition, the drive motor plays the role of an alternator (generator) when decelerating or braking to charge the high-voltage battery.

The HSG performs restart/cold start of the engine while the vehicle is running, or charges the high-voltage battery.
