The utility model relates to an accurate control circuit of energy storage battery electric current, including charging the machine, the load, energy storage battery and a set of above control of charge and discharge circuit more than a set of, the every control of charge and discharge of group circuit has 1 the 1st control junction, the 2nd control junction and 1 the 3rd control junction, a control junction of the every control of charge and discharge of group circuit is connected to the positive pole of the anodal of load and the machine that charges, the 2nd control junction of the every control of charge and discharge of group circuit is connected to the positive pole that this group corresponds energy storage battery, the 3rd control junction of the every control of charge and discharge of group circuit is connected to the negative pole that this group corresponds energy storage battery, the negative pole of load and the negative pole of the machine that charges. The every energystorage battery of group of this circuit be all to should there being the control of charge and discharge circuit, and the charging of every energy storage battery of group, discharge current can bothcarry out single control, realize singly organizing the utilization of energy storage battery energy maximize, have not only guaranteed whole energy storage system's operation safety, have improved life and economic benefits in addition.
