Title:
BATTERY SELF-HEATING SYSTEM, ELECTRICAL DEVICE, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/082155
Kind Code:
A1
Abstract:
Disclosed in the present application are a battery self-heating system, an electrical device, and a vehicle. The battery self-heating system comprises a first battery, a second battery, a converter, a motor, a first switch device and a second switch device, the first battery and the second battery being connected by means of the first switch device, a negative electrode of the first battery and a negative electrode of the second battery being both connected to a first end of the converter, and the second switch device being arranged between the negative electrode of the first battery and the first end of the converter. One of a positive electrode of the first battery and a positive electrode of the second battery is connected to the motor, and the other one is connected to a second end of the converter. Thus, by means of controlling the motor and the converter, the first battery and the second battery can be alternately charged and discharged, and further self-heating of the first battery and the second battery can be performed by using oscillating current generated by alternate charging and discharging, so that compared with external heating, the present application can effectively raise heating efficiency, and does not need addition of an extra heating apparatus, thus achieving lower costs.
