Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to a bidirectional charging circuit, device and control method for storage equipment. Background technique [0002] The storage battery is charged by the charging module, and when the electric energy is output, the inverter module converts it into voltages of different specifications to supply power to the powered equipment. However, existing storage batteries cannot be simultaneously charged while being discharged. In the existing technical solutions, the charging circuit and the discharging circuit are independent of each other, and the two independent modules occupy a large amount of physical space, which makes the bidirectional charging circuit with the charging module and the discharging module larger in scale, and the circuit is complicated, and the circuit There are many components in the middle, which makes the volume of the whole circuit larger; in addition, the ...
