The invention discloses an electric automobile battery range extending device. The electric automobile battery range extending device comprises: a standby battery, a step-up DC/DC and a step-down DC/DC which are connected between an original vehicle battery bus and a standby battery in parallel with the original vehicle battery bus of the electric vehicle and adopt a voltage and current double-closed-loop control mode, a driving detection sensor for monitoring dynamic and static states of the electric automobile, and a protection circuit and an external charging circuit which are connected with the standby battery. According to the invention, the mileage of any electric vehicle can be increased under the condition of not changing three electric vehicles (batteries, motors and motor controllers) of the electric vehicle, the load of the battery of the original vehicle is greatly reduced, the cycle index of the battery of the original vehicle is reduced, the service life of the battery ofthe original vehicle is prolonged, and great economic value is achieved.

    本发明公开了一种电动汽车电池增程装置,包括备用电池,与电动汽车的原车电池母线并联地连接于原车电池母线与备用电池之间并采用电压电流双闭环控制方式的升压型DC/DC和降压型DC/DC,用于监测电动汽车的动静状态的行驶检测传感器,以及与备用电池连接的保护电路和外接充电电路。本发明在无需改动电动汽车三电(电池、电机、电机控制器)情况下能实现对任何电动汽车行驶里程的增加,并极大地减小了原车电池的负荷,减少原车电池循环次数,延长了原车电池的使用寿命,具有极大的经济价值。
