Battery module, battery pack, apparatus, and failure handling method

A battery module, wherein the battery module comprises:

• a plurality of battery units configured to be serial-connected, wherein the plurality of battery units comprise a failed battery unit and at least one non-failed battery unit after the battery module fails, each battery unit comprises two electrode terminals and a top cover;
• a first conductive part comprising a first connecting section, and a second connecting section, wherein the first connecting section is electrically connected to one of the two electrode terminals of the failed battery unit, the second connecting section is electrically connected to the top cover between the two electrode terminals of the failed battery unit;
• and
• a second conductive part comprising a third connecting section, and a fourth connecting section, wherein the third connecting section is electrically connected to the other one of the two electrode terminals of the failed battery unit, the fourth connecting section is electrically connected to the top cover between the two electrode terminals of the failed battery unit;
• wherein the first conductive part, the second conductive part, and the top cover make a current bypass an electrode assembly of the failed battery unit so that the battery module resumes working;
• wherein the at least one non-failed battery unit comprises two non-failed battery units that are located upstream and downstream of the failed battery unit respectively, and the first conductive part and the second conductive part serial-connect the two non-failed battery units;
• wherein the battery module further comprises:
• a plurality of connecting plates, configured to serial-connect the electrode terminals of the plurality of battery units;
• and
• the first conductive part and the second conductive part serial-connect the two non-failed battery units through at least one of:
• the connecting plate connecting to at least one of the two electrode terminals of the failed battery unit, or
• at least one of the two electrode terminals of the failed battery unit;
• wherein at least one of the first connecting section, the second connecting section, the third connecting section, and the fourth connection section comprises a plurality of metal straps connected to the at least one of the two electrode terminals of the failed battery unit or the connecting plate that connects to the at least one of the two electrode terminals of the failed battery unit.
