The invention relates to a multi-battery parallel-series power supply control method for an electric vehicle, the electric vehicle comprises a control unit, a plurality of parallel battery units and a power driving unit, each parallel battery unit comprises a plurality of batteries which are connected in parallel, the control unit executes the following steps for each parallel battery unit: the control unit receives an initial voltage value of each battery, and takes the maximum initial voltage value as a system voltage value of the parallel battery unit; calculating a difference value between the system voltage value and the initial voltage value of each of the other batteries; judging whether the difference value of each battery is greater than a voltage threshold value or not; when the difference value of the battery is not larger than the voltage threshold value, the control unit controls the battery with the system voltage value and a switch module of the other batteries to be all switched on so as to supply power to the power driving unit, high electricity output efficiency is provided for the electric vehicle, and endurance is prolonged.

    本发明为一种电动车的多电池并串联供电控制方法,该电动车包含有一控制单元、多个并联电池单元及一动力驱动单元,各该并联电池单元包含多个电池相互并联,其中,该控制单元针对每一个该并联电池单元执行:该控制单元接收各该电池的一初始电压值,并以最大的该初始电压值作为该并联电池单元的一系统电压值;计算该系统电压值与其它各电池的初始电压值之间的一差异值;判断各该电池的该差异值是否大于一电压门槛值;当该电池的该差异值不大于该电压门槛值,该控制单元控制具有该系统电压值的该电池以及所述的其他该电池的一开关模组全部导通,以供电给该动力驱动单元,提供较高的出电效率给该电动车,延长续航力。
