How does a hybrid car battery work?

Hybrid vehicle batteries work on the principle that batteries in hybrid vehicles help improve fuel economy, which has become the core of the technology. They power electric motors, which typically propel hybrid cars at lower speeds. This reduces the pressure on the petrol engine and prolongs the vehicle's fuel consumption between trips to the gas station.A hybrid battery/supercapacitor energy storage system for electric vehicles complements the advantageous features of each module. In this arrangement, the adverse effects of current fluctuations on the battery are reduced, and its run time is extended.Whereas a hybrid works by using the forward motion of the wheels to turn an electric motor. This generates electricity and helps slow down the vehicle. Electric motor drive/assist. The electric motor provides power to help the engine accelerate, pass or climb hills. This allows the use of smaller, more efficient engines. In some hybrids, there is only an electric motor.
