Kia Niro 2017 (DE HEV) Service Manual / Hybrid Control System / Description and operation

Hybrid Electric Vehicle (HEV)

Hybrid Electric Vehicle (HEV) uses a hybrid power source in the form of combination of combustion engine and electric motor. This will increase the fuel efficiency and emit less harmful exhaust emissions over conventional vehicles with combustion engine system.
In Electric Vehicle (EV) mode, the HEV is driven by only the electric motor, but engine supports the motor in case the vehicle needs more power (HEV Mode).
The electric motor not only drives the vehicle but also generates electric energy during regenerative braking for charging the high voltage battery.
