Simply said, a hybrid car moves by combining at least one electric motor with a gasoline engine, and the system recovers energy through regenerative braking. The electric motor does all of the work occasionally, the gas engine does it other times, and they both work together at other times. As a result, less gasoline is burnt, resulting in higher fuel economy. In some cases, adding electric power can even improve performance.
All of them use a high-voltage battery pack (different from the car’s standard 12-volt battery) that is recharged by absorbing energy from deceleration that would otherwise be wasted to heat created by the brakes in traditional cars. (This is accomplished through the use of regenerative braking.) The gas engine is also used to charge and maintain the battery in hybrids. Car manufacturers utilize various hybrid designs to achieve various goals, ranging from optimum fuel efficiency to keeping vehicle costs as low as feasible.
