The invention discloses a range-extending power supply system for an electric vehicle. The range-extending power supply system comprises a frame, front wheels and rear wheels, the electric bicycle further comprises a rechargeable storage battery, a front driving motor and a rear driving motor. One side of the front driving motor is in transmission connection with a generator; an inverter is arranged at the output end of the generator, and the generator is electrically connected with a rechargeable storage battery through the inverter; one side of the front driving motor is in transmission connection with a generator; one side of the front driving motor is in transmission connection with a range extending motor; the range extending motor and the rechargeable storage battery are electrically connected with the rear driving motor; the voltage of the electricity generated by the generator is reduced through the first inverter, and then the two rechargeable storage batteries are charged through the quick charger; the first-time kinetic energy recovery is completed, and the charging of the storage battery is met; and electricity generated by the range extending motor passes through the second inverter and then is directly supplied to the rear driving motor for use, so that driving of rear wheels is completed, and the driving requirement of the electric vehicle is met.

    本发明公开了一种电动汽车增程供电系统,包括车架,前侧车轮、后侧车轮;其还包括可充电的蓄电池、前驱动电机、后驱动电机;所述前驱动电机的一侧传动连接有发电机;所述发电机的输出端设置有逆变器,且所述发电机通过逆变器与可充电的蓄电池电性连接;所述前驱动电机的一侧传动连接有发电机;所述前驱动电机的一侧传动连接有增程电机;所述增程电机、可充电的蓄电池均与后驱动电机电性连接;发电机发出的电通过1号逆变器降压,然后再通过快速充电器给两块可充电的蓄电池进行充电;进而完成第一次的动能回收,满足蓄电池的充电;增程电机发出的电通过2号逆变器然后直供给后驱动电机使用,进而完成对后侧车轮的驱动,满足电动车的行驶需求。
