Beschreibung
Zusammenfassung:	The invention discloses an electric vehicle battery self-heating system and an electric vehicle. The electric vehicle battery self-heating system comprises a first battery, a second battery, a motor inductor, an inverter and a control unit. The voltage of the first battery is higher than that of the second battery; the first end of the motor inductor is connected with the first end of the second battery, and the second end of the motor inductor is connected with the first end of the inverter; the second end of the inverter is connected with the first end of the first battery; the third end of the inverter is connected with the second end of the first battery and the second end of the second battery; the first end of the first battery and the first end of the second battery are consistent in polarity; and the control unit is used for adjusting the duty ratio of a switching tube in the inverter, so that pulse current is generated between the first battery and the second battery, and the first battery and the se
