Abstract: An energy storage apparatus and an energy storage system. The energy storage apparatus includes a cell and a heating circuit. The heating circuit includes a heating resistor and a switch. The heating resistor and the switch are configured to be connected in series to a power supply loop. The switch in the heating circuit is controlled to be on and off, so that the heating resistor is intermittently connected to and disconnected from the power supply loop. The switch may control, based on a power supply voltage provided by the power supply loop, turn-on time and turn-off time of a line between the power supply loop and the heating resistor in each switching cycle, to dynamically adjust an average heating power of the heating circuit.
