Claim 0:
1. A battery module, comprising:
a battery unit;
an energy storage element, coupled to the battery unit;
a switch, coupled to the energy storage element;
a functional circuit, respectively coupled to the battery unit and the energy storage element; and
a control unit, respectively coupled to the functional circuit and the switch, configured to control the functional circuit to cause the energy storage element to be coupled to the battery unit so that the battery unit charges the energy storage unit, or configured to control the functional circuit to cause the energy storage element to be decoupled with the battery unit so that a discharge path is formed;
wherein the energy storage element is an inductor;
wherein the battery module further comprises:
a transformer circuit used to output a voltage to the functional circuit;
a first capacitor, wherein a first end of the first capacitor is coupled to a second end of the inductor; and
a second capacitor, wherein a first end of the second capacitor is coupled to a second end of the switch;

wherein a first end of the inductor is coupled to one of a plurality of output ends of the functional circuit, a first end of the switch is coupled to the first end of the inductor, a first end of the battery unit is coupled to the second end of the switch, a second end of the battery unit is coupled to another one of the output ends of the functional circuit, and a second end of the first capacitor and a second end of the second capacitor are reference grounded, and the control unit is coupled to one or more control ends of the functional circuit and a control end of the switch.
