A power-supplying battery 3 of an electric vehicle includes a plurality of chargeable batteries 1 grouped into at least two first battery groups 2, where the batteries of each first battery group are divided into at least two second battery groups 11 that are electrically connected in parallel. Each first battery group is electrically connected to each other in parallel to form a complete set of the power-supplying battery. During charging, an external power source 5 is connected to the power-supplying battery, and a current or voltage of the charging power source is supplied, in a divided manner, to charge each first battery group and its second battery groups. During discharge, a voltage or a current of each first battery group is combined with each other for output as a total. A control circuit 4 for controlling and regulating electricity supplied to or from the battery may be provided, comprising a first connection port 41 and a plurality of second connection ports 42. The first connection port for connection to second positive/negative contacts 31 of the power-supplying battery and the second connection port for connection to one of the charging power source 5 and an external loading 6.
