Title:
BATTERY MODULE, BATTERY PACK, POWER CONSUMPTION APPARATUS, AND FAILURE PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/196729
Kind Code:
A1
Abstract:
Provided are a battery module, a battery pack, a power consumption apparatus, and a failure processing method. The battery module comprises: a plurality of battery cells, wherein each of the plurality of battery cells comprises a top cover, and when a battery module fails, the plurality of battery cells further comprise a battery cell that fails; connection pieces for connecting the plurality of battery cells in series, wherein the connection pieces comprise a first connection piece which is connected to the battery cell that fails; and a conductive component for electrically connecting to the top cover of the battery cell that fails, wherein at least one of the first connection piece and the conductive component is provided with a cooperation portion, and the cooperation portion is used for cooperating with the other one of the first connection piece and the conductive component, so as to realize, by means of the conductive component, electrical connection between the top cover of the battery cell that fails and the first connection piece, such that the battery module resumes working. In the present application, a battery cell that fails can be removed from a circuit of a battery module, without it being necessary to replace the whole battery module. The conductive component is connected to the first connection piece via the cooperation portion, thereby improving the reliability of the connection between the two.
