The invention discloses a battery self-heating system, electric equipment and a vehicle, the battery self-heating system comprises a first battery, a second battery, a converter, a motor, a first switching device and a second switching device, and the first battery and the second battery are connected through the first switching device; the negative electrode of the first battery and the negative electrode of the second battery are both connected with the first end of the converter, a second switching device is arranged between the negative electrode of the first battery and the first end of the converter, one of the positive electrode of the first battery and the positive electrode of the second battery is connected with the motor, and the other is connected with the second end of the converter. The first battery and the second battery can be alternately charged and discharged by controlling the motor and the converter, so that the first battery and the second battery can be self-heated by utilizing oscillating current generated by alternate charging and discharging, the heating efficiency can be effectively improved compared with external heating, additional heating equipment does not need to be added, and the cost is reduced. And the cost is lower.

    本申请公开了一种电池自加热系统、用电设备及车辆,电池自加热系统包括第一电池、第二电池、变换器、电机以及第一开关器件和第二开关器件,第一电池和第二电池通过第一开关器件连接,第一电池的负极和第二电池的负极均与变换器的第一端连接,第一电池的负极与变换器的第一端之间设置有第二开关器件,第一电池正极和第二电池的正极其中之一与电机连接,另一个与变换器第二端连接。如此通过控制电机和变换器可以使第一电池和第二电池之间进行交替充放电,进而可以利用交替充放电产生的振荡电流对第一电池和第二电池进行自加热,相比于外部加热可以有效提高加热效率,并且无需增加额外的加热设备,成本更低。
