Abstract: A system and method for battery charge/discharge equalization, the method including performing, for each battery module of M battery modules of a battery component, determining, by a control unit of the respective battery module, a reference value of a power parameter, wherein M is a positive integer greater than 1, where each battery module of the M battery modules includes the control unit, a direct current-direct current (DCDC) converter, and an energy storage unit, wherein the control unit is electrically connected to the DCDC converter, and the DCDC converter of each battery module is electrically connected to a load or a power supply, and where the reference value is associated with equalizing charging/discharging of the M battery modules, and controlling, by the control unit of the battery module using the DCDC converter, an value of the power parameter to be equal to the reference value.
