Abstract: A power supply management system includes a monitoring module and a plurality of battery modules. The battery module includes a BMS, a DC/DC converter, and a plurality of battery packs. When the battery packs of the plurality of battery modules are charged or discharged by using the DC/DC converter, the monitoring module may detect charge/discharge rates of the battery modules, and when the charge/discharge rates of the battery modules are less than a specified threshold, control a part of battery modules that are being charged or discharged to stop being charged or discharged. After a quantity of battery modules that are being charged or discharged is decreased, the charge/discharge rates are increased.
