Abstract: This application relates to a liquid leak detection method and apparatus, a battery control unit, and a battery management system. The method includes: obtaining a gas concentration detection signal output separately by a plurality of target gas sensors in a battery box, where the gas concentration detection signal is used for indicating a measured gas concentration; obtaining position information of each target gas sensor in the battery box; and determining a leaking region in the battery box based on the gas concentration detection signal and the position information of each target gas sensor. To sum up, in an embodiment of this application, the leaking region in the battery box can be located by analyzing the gas concentration detection signals and position information of a plurality of target gas sensors in the battery box, so that prompt information used for indicating the leaking region can be output subsequently.
