Abstract
The invention provides a branch disconnection detection method, device and equipment, a medium and a program product, and relates to the technical field of vehicles. The method comprises the following steps: in a pre-charging process, obtaining a current value of each branch in a multi-branch battery system; determining whether the current value of each branch belongs to a preset offline current range or not; if the target current value belonging to the preset offline current range exists, determining that a target branch corresponding to the target current value is offline; wherein the number of the target current values is at least one; outputting fault information; wherein the fault information is used for indicating that the target branch is disconnected. By adopting the method provided by the embodiment of the invention, the reliability of the multi-branch battery system can be improved, and the service life of the battery is guaranteed.
