Document Type and Number:
WIPO Patent Application WO/2023/225974
Kind Code:
A1
Abstract:
A thermal runaway detection method, capable of effectively improving the security performance of a battery swapping cabinet (13) and a battery swapping station (11). The method comprises: a battery management unit (BMU) (131) determines, according to a battery parameter of a battery (142) in a battery swapping cabinet (13), whether thermal runaway has occurred in the battery swapping cabinet (13), wherein the battery parameter comprises the temperature of a battery cell in the battery (142) and/or the voltage of the battery cell; and if it is determined that thermal runaway has occurred in the battery swapping cabinet (13), the BMU (131) sends fault information to a station control system (151) of the battery swapping station (11), wherein the fault information is used for indicating that thermal runaway has occurred in the battery swapping cabinet (13).
