Beschreibung
Zusammenfassung:	A battery self-heating system, a control method therefor, and an electric vehicle, wherein the battery self-heating system comprises: a three-phase motor, a battery pack, a three-phase inverter, and a switch module. The method for controlling the battery self-heating system comprises: acquiring battery pack temperature information; when according to the battery pack temperature information it is determined that the battery pack requires self-heating, obtaining voltage information between a first end and a second end of the switch module; according to the voltage information between the first end and the second end of the switch module, controlling the switch module to achieve self-heating of the battery pack; when according to the battery pack temperature information it is determined that the battery pack does not require self-heating, obtaining electric current information between the first end and the second end of the switch module; and according to the electric current information between the first end an
