When vehicle is in damped condition, electric vehicle control system controlled motor is in generating state, and now motor is defeated
Go out that torque is contrary with vehicle heading it is meant that motor plays braking action and kinetic energy is converted to electric energy is filled with accumulator.
The main flow energy regenerating mode that energy regenerating is existing electric motor car is realized using motor regenerative braking, but deposits
In following defect:
1st, low speed cannot be braked.
When motor is in regenerative braking state, the induction electromotive force that motor produces is proportional to motor speed, garage
Sail that speed is low to lead to machine induced electromotive force low, and then output current is low, also implies that brake force is little, therefore, if adopted
Motor regenerative braking purely, it may appear that motor brake force reduces and the situation of reduction with rotating speed, is finally turning
Just brake force is lost, at this moment brakes has to allow automobile obtain enough systems plus former frictional damping when speed is slower
Power is that is to say, that motor regenerative braking purely can neither provide brake force to be also impossible to realize kinetic energy in low speed
Reclaim completely；
2nd, instantaneous braking energy cannot absorb in time.
, from the beginning of initial velocity 80km/h, being braked with deceleration -3m/s^2 is needed to stopping taking the automobile as 1.2t for the weight as a example
Want time 7.5s, discharge kinetic energy 2,900,000j, energy release mean power is 400kw, and so highdensity energy is to drive
That motor cannot fully absorb and be converted into electric energy.
