The basic principle with hybrid vehicles is that the different motors work better at different speeds.
Hybrid car motor power.
The battery can also power auxiliary loads and reduce engine idling when stopped.
Benefits the main benefit derived from hybrids is very high gas mileage.
One way known as a parallel hybrid has a fuel tank that supplies gasoline to the engine and a set of batteries that supplies power to the electric motor both the engine and the electric motor can turn the transmission at the same time and the transmission then turns the wheels.
A hybrid electric vehicle cannot be plugged in to charge the battery.
Mild hybrid is a vehicle that cannot be driven solely on its electric motor because the electric motor does not have enough power to propel the vehicle on its own.
A hybrid vehicle uses two or more distinct types of power such as submarines that use diesel when surfaced and batteries when submerged.
You can combine the two power sources found in a hybrid car in different ways.
Instead the battery is charged through regenerative braking and by the internal combustion engine.
Other means to store energy include pressurized fluid in hydraulic hybrids.
Often the hybrid car will derive power from both the electric and ice at the same time while sometimes power is supplied by the electric motor only which results in a very quiet ride.
The extra power provided by the electric motor can potentially allow for a smaller engine.
