Abstract

The present disclosure provides an apparatus for controlling battery module, power supply device and power supply system. The apparatus includes a switch circuit and a first power controller. The first power controller is coupled with the switch circuit, a first busbar, a second busbar, and a battery module, and is configured to: control the switch circuit to conduct in a first direction, in a case of the voltage between the first busbar and the second busbar being greater than the voltage of the battery module and the power of the battery module being smaller than a first preset power; and control the switch circuit to conduct in a second direction, in a case of the voltage between the first busbar and the second busbar being smaller than the voltage of the battery module and the power of the battery module being greater than a second preset power.
