The invention provides a power supply battery of an electric vehicle. The power supply battery comprises a plurality of rechargeable batteries. The plurality of rechargeable batteries are divided into at least more than two first battery packs; the plurality of rechargeable batteries in each first battery pack are further divided into at least more than two second battery packs; the second battery packs are electrically connected in parallel, and the first battery packs are electrically connected in parallel; and a complete power supply battery is formed. When the power supply battery is charged, an external preset charging power supply is electrically connected with the power supply battery, so that the current and the voltage of the charging power supply respectively charge each first battery pack and each second battery pack in a shunt mode; when the power supply battery undergoes discharging, the voltage value and the magnitude of current of each first battery pack are collected and then output, so that the purpose that the power supply battery can stably perform charging/discharging operation is achieved, and meanwhile the situation that high temperature is likely to be generated in the charging process of the power supply battery is avoided.
一种电动载具的供电电池,包括有多个充电电池;将多个充电电池分成至少两个以上的第一电池组,每一个第一电池组其内部的多个充电电池再分成至少两个以上的第二电池组,每个第二电池组以并联方式电性连接,再将每一个第一电池组以并联方式相互电性连接,形成一完整的供电电池。当供电电池进行充电时,由外部预设的充电电源与供电电池电性导通,使充电电源的电流及电压以分流方式分别对每一个第一电池组及第二电池组进行充电;当供电电池进行放电时,使每一个第一电池组的电压值及电流量汇集后并输出,达到供电电池能稳定进行充/放电作业的目的,同时避免供电电池充电过程易产生高温的情况。
