Abstract： In order to obtain high charge current acceptance in energy regeneration for battery during electric brake of light electric vehicle(EV)， a half/full bridge of PWM switching control method was proposed. Based on a BLDCM PWM converter circuit， the switched special PWM control was realized by braking signal during normal and energyregeneration modes. The quick periodical swift charge and recharge for battery can be realized with high efficiency， and more energy can be returned in the energy regeneration period. The performance of the proposed method was compared with the Boost converter energy regeneration method through experiments. The results show that compared with the Boost converter energy regeneration method， the control method can decrease the average resistance of battery by 216 mΩ，and increase the average charge current acceptance by 6.2% with enhanced driving range of 6.6% for EV under the same driving condition.
