直流无刷轮毂电机能量回收和再生制动系统及电动车
摘要：
本申请公开了一种直流无刷轮毂电机能量回收和再生制动系统及电动车，包括蓄电池组、钥匙开关、前进后退开关、加速车把、刹车开关、直流无刷轮毂电机控制器和直流无刷轮毂电机。由于释放加速手把时，直流无刷轮毂电机控制器用于控制直流无刷轮毂电机从电动机状态转变为发电机状态，将车辆动能转变为电能，回充给蓄电池组，在发电的同时，直流无刷轮毂电机产生再生制动力矩，使车辆平稳停止，提高了车辆制动的安全，减少了机械制动的磨损，保护和延长了机械制动器使用寿命，由于能量回收和再生制动是个全自动过程，为操作者带来了极大的操作方便，提高车辆行驶安全性能。
摘要（英）：

The invention discloses a direct-current brushless hub motor energy recovery and regenerative braking system and an electric vehicle. The system comprises a storage battery pack, a key switch, a forward and backward switch, an acceleration handlebar, a braking handlebar, a direct-current brushless hub motor controller and a direct-current brushless hub motor. When the acceleration handlebar is released, the direct-current brushless hub motor controller controls the direct-current brushless hub motor to be in a generator state from a motor state, so that vehicular kinetic energy is converted into electric energy which is charged back to the storage battery pack; during power generation, the direct-current brushless hub motor generates a regenerative braking torque to stably stop the vehicle, and accordingly braking safety of the vehicle is improved, abrasion in mechanical braking is reduced, and the service life of a mechanical brake is protectively prolonged. Due to automation in energy recovery and regenerative braking, great operation convenience is brought to an operator, and driving safety of the vehicle is improved.
