Speed changer under meaning, when being used in combination with accumulator (such as battery, capacitor etc.), which fills but also as energy adjustment
It sets, completes to the separately adjustable of speed and torque.The advantages of serial hybrid system, is that structure is simple, flexible layout, but due to
Whole power will be therefore very high to the power requirement of motor by generator and motor, and volume is big, weight weight.Separately
Outside, since energy transport is by needing by machine-electricity, the conversion twice of electricity-machine, so the efficiency of whole system is lower.
In motor parallel hybrid system, have two parallel independent power transmission chains: one by traditional mechanical transmission group
At another is made of motor-battery system.Mechanical transmission is responsible for completing the adjusting to speed, and motor-battery system
Then complete the adjusting to power or torque.In order to give full play to the potential of whole system, mechanical transmission is also needed using nothing
