Hybrid Electric Vehicles are powered by an IC (Internal Combustion) engine and an electric motor, utilizing energy stored in batteries. A hybrid electric vehicle does not require to be plugged in to charge the battery, the battery is charged through regenerative braking and by the IC engine
The low-voltage auxiliary battery provides electricity to start the vehicle before the traction battery is engaged and it also provides power to vehicle accessories.
DC/DC converter converts higher-voltage DC power from the traction battery pack to the lower-voltage DC power which is required to run vehicle accessories and recharge the auxiliary battery.
Generates electricity from the rotating wheels while braking, transferring that energy back to traction battery pack.
Electric traction motor:
This motor drives the vehicle’s wheels by using the power from traction battery pack.
The exhaust system removes the exhaust gases from the engine out through the tailpipe. A three-way catalyst is designed to reduce engine-out emissions within the exhaust system.
A nozzle from a fuel dispenser attaches to the receptacle on the vehicle to fill the tank.
This tank stores fuel on board the vehicle until it's needed by the engine.
Internal combustion engine (spark-ignited):
Fuel is injected into either the inlet manifold or the combustion chamber, where it is combined with air, and the air/fuel mixture is ignited by the spark from a spark plug.
Power electronics controller:
This unit controls the speed of the electric traction motor and its torque by managing the flow of electrical energy delivered by the traction battery.
Thermal system (cooling):
This system maintains an optimum operating temperature range of the engine, electric motor, power electronics, and other components.
Traction battery pack:
Stores electricity for use by the electric traction motor.
The transmission transfers mechanical power from the engine and/or electric traction motor to drive the wheels.
