New approach is opened up.It is most representative to have serial hybrid system and mixed stocker in parallel in numerous power assembly design cases
Two kinds of system.In motor serial hybrid system, internal combustion engine, generator, motor, shafting, driving wheel form a concatenated power
Chain, power assembly structure are extremely simple.Wherein, generator and motor combination can be considered the speed changer under traditional sense.When with
Accumulator, such as battery, when capacitor etc. is used in combination, the speed changer is completed but also as energy conditioner to speed and torsion
Square it is separately adjustable.
Motor parallel system has two parallel independent power transmission chains.One is made of traditional mechanical transmission, another
Item is made of motor and battery system.Mechanical transmission is responsible for completing the adjusting to speed, and motor and battery system are then completed
Adjusting to power or torque.For the potential for giving full play to whole system, mechanical transmission is also needed using stepless gearing method.
The advantages of serial hybrid system, is that structure is simple, flexible layout.But since whole power pass through generator and electricity
Motivation, therefore the power requirement of motor is high, volume is big, weight weight.Simultaneously as energy transport passes through machine twice and electricity,
The conversion of electricity and machine, the efficiency of whole system are lower.In parallel hybrid system, only partial power passes through electric system, because
This, it is relatively low to the power requirement of motor, total system it is high-efficient.However, this system needs two sets of independent subsystems, make
Valence is high, is generally only used for Weak mixing system.
