| description | The utility model relates to a power supply circuit, an energy storage device and an energy storage system. The power supply circuit comprises an AC/DC conversion circuit, a DC/DC conversion circuit, a first DC circuit and a second DC circuit. The first direct-current circuit and the second direct-current circuit are arranged at the two ends of the DC/DC conversion circuit respectively, so that power supplies with different voltages can supply power to the target direct-current equipment or the target direct-current equipment can output different voltages. When a plurality of direct-current devices are connected, the DC/DC conversion circuit of the power supply circuit can be utilized for voltage conversion, so that an additional conversion circuit is omitted, and the connection cost of the plurality of direct-current devices and the design difficulty of the circuit are reduced.
本申请涉及一种供电电路、储能装置及储能系统。供电电路包括AC/DC变换电路、DC/DC变换电路、第一直流电路和第二直流电路。通过在DC/DC变换电路的两端分别设置第一直流电路和第二直流电路，可以使电压不同的电源为目标直流设备进行供电或使目标直流设备输出不同的电压。 |
