Plug-in hybrid vehicle energy flow

Kia hybrid system notifies the drivers of energy flow in various operating modes. Eleven modes show drivers the current operating condition.

Vehicle Stop

The mode means the vehicle is stopped. (There is no energy flow.)

EV Propulsion

Electric power is used to move the vehicle.

(Battery → Wheel)

Power Assist

(Battery & Engine → Wheel)

Engine Only Propulsion

Engine power is used to move the vehicle.

(Engine → Wheel)

Engine Generation

Vehicle is stopped with the Engine charging the hybrid battery.

(Engine → Battery)

Regeneration

(Wheel → Battery)

Engine Brake

The vehicle is being slowed down by engine compression.

(Wheel → Engine)

Power Reserve

Engine is both driving the vehicle and charging the hybrid battery.

(Engine → Wheel & Battery)

Engine Generation/Motor Drive

The vehicle is being slowed down by engine compression and regenerative braking. The hybrid battery is being charged by regenerative braking.

(Engine → Battery → Wheel)

Engine Generation/Regeneration

The engine and regenerative braking system charge the hybrid battery driving deceleration.

(Engine & Wheel → Battery)

Engine Brake/Regeneration

The engine compression can be used to slow the vehicle. The regenerative braking system can be used to charge the hybrid system.
