Abstract: A charging control method, an energy storage module, and a powered device. The method includes: obtaining a sampling voltage of an input port of a DC-DC unit; determining a charging parameter of the DC-DC unit for an energy storage unit based on the sampling voltage of the input port of the DC-DC unit and a preset constant voltage of the input port of the DC-DC unit, where a sum of a charging electricity quantity reflected by the charging parameter and a charging electricity quantity of a load is equal to a maximum output electricity quantity of an input source; and after the charging parameter is determined, charging the energy storage unit by using the charging electricity quantity reflected by the charging parameter.
