The invention provides a matching device for battery interconnection and an electric vehicle. The device comprises a motor, a controller, a first contactor, a second contactor, a driving plate, a first battery and a second battery. When the whole vehicle stands still or is charged, the controller does not send a control signal to the driving plate, and the first battery and the second battery are connected in parallel; when the whole bicycle is ridden, the controller detects the rotating speed of the motor, and the current bicycle speed is obtained according to the rotating speed of the motor; the current vehicle speed is compared with the preset vehicle speed, if the current vehicle speed is smaller than the preset vehicle speed, a control signal is not sent to the driving board, the first contactor and the second contactor do not act, the first battery and the second battery are connected in parallel, the battery voltage at the two ends of the controller is U, and the capacity is 2C; and if the current vehicle speed is larger than the preset vehicle speed, the controller controls the first contactor to be attracted through the driving plate and then controls the second contactor to be attracted through the driving plate, the first battery and the second battery are connected in series, the voltage of the batteries at the two ends of the controller is 2U, and the capacity is C.
本发明提供了电池互联的匹配装置和电动车,包括:电机、控制器、第一接触器、第二接触器、驱动板、第一电池和第二电池;当整车静置或充电时,控制器不对驱动板发送控制信号,第一电池和第二电池并联;当整车骑行时,控制器检测电机的转速,根据电机的转速得到当前车速;将当前车速与预设车速进行比较,如果当前车速小于预设车速,则不对驱动板发送控制信号,第一接触器和第二接触器不动作,第一电池和第二电池并联,控制器两端的电池电压为U,容量为2C;如果当前车速大于预设车速,控制器通过驱动板控制第一接触器吸合后,再通过驱动板控制第二接触器吸合,第一电池和第二电池串联,控制器两端的电池电压为2U,容量为C。
