Electric Hybrid Cars do not need an external power source to replenish their batteries because their main source of power is gasoline. Hybrid electric vehicles are propelled by an internal combustion engine and one or more electric motors that make use of battery energy. The battery of a hybrid electric car cannot be charged by plugging it in. Instead, the battery is charged by the internal combustion engine and regenerative braking. A smaller engine could be possible thanks to the electric motor's added power. Additionally, the battery can decrease engine idle while stopped and power auxiliary loads. Together, these components improve fuel efficiency without compromising performance.

The components of these cars are

The low-voltage auxiliary battery of an electric drive vehicle powers accessories as well as starting the vehicle before the traction battery kicks in. This device, known as a DC/DC converter, transforms higher-voltage DC power from the traction battery pack into the lower-voltage DC power required to operate the vehicle's accessories and replenish the auxiliary battery.

Electric generator releases power during braking by tackling the motion of the wheels, then gives that energy back into the traction battery pack. Some automobiles employ motor generators that act as both drives and regenerators.

Electric traction motor powers the wheels of the vehicle by drawing energy from the traction battery pack. Some automobiles employ motor generators that serve as both drives and regenerators.

Exhaust system sends the engine's exhaust gases out the tailpipe. The triple way catalyst in the exhaust system is designed to reduce engine-out emissions.

Gasoline filler fill the tank, a nozzle from a fuel dispenser is attached to the tank's receptacle on the car.

Fuel tank holds gasoline within the car until the engine needs it.

Spark-ignited internal combustion engine, in this setup, fuel is pumped into the combustion chamber or the intake manifold, where it is mixed with air. A spark from a spark plug then ignites the air/fuel combination. The power electronics controller regulates the flow of electrical energy from the traction battery, regulating the torque and speed of the electric traction motor.

Thermal system keeps the engine, electric motor, power electronics, and other components within a safe operating temperature range. Electricity is stored in the traction battery pack, which the electric traction motor will utilise.

The gearbox transforms the traction motor or engine's electrical power into mechanical power that turns the wheels.
