Abstract: A power module includes a power input end, a first DC/DC power converter, a second DC/DC power converter, a switching unit, and at least two load output ends. A first input end of the first DC/DC power converter and a second input end of the second DC/DC power converter are coupled to a first power supply by using the power input end of the power module, a first output end of the first DC/DC power converter and a second output end of the second DC/DC power converter are coupled to one end of the switching unit, and the other end of the switching unit is coupled to load by using any one of the at least two load output ends of the power module.

Abstract: A three-electrode battery (10) and an energy storage system are disclosed. The three-electrode battery (10) includes a battery management unit (14), a housing (11), and a reference electrode (13) and a battery cell (12) that are disposed in the housing (11). A detection part (131) of the reference electrode (13) is located in the battery cell (12). A reference electrode tab (132) is located outside the battery cell (12). The battery management unit (14) is connected to the reference electrode tab (132) and a negative electrode tab (122) of the battery cell (12), so that a voltage between the reference electrode (13) and a negative electrode of the battery cell (12) can be collected in real time, and a charging current of the battery (10) is controlled based on the negative electrode potential, so that the charging current can be optimized and adjusted in real time.
