  "textContent": "Embodiments of this application provide 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. By using the method, in a scenario in which the input source is weak, the input source can always maintain maximum output power, and an input voltage of the energy storage module can be stabilized, thereby avoiding a phenomenon of repeated charging and discharging of the energy storage module. In addition, an increase in hardware costs can be avoided, and coupling between the energy storage module and another module can be reduced.",
