Description

Technical Field

[0001] The utility model relates to the technical field of battery safety detection, in particular to a device based on detecting whether a low-voltage wire harness of a battery is charged. Background Art

[0002] During equipment wiring operations, equipment short circuits and damage due to incorrect wiring are common. For example, consider two battery modules, A and B, with different serial and parallel configurations and different low-voltage communication line pin definitions. However, the low-voltage jacks on these two modules lack fool-proofing, making it easy to mistakenly plug the low-voltage wire from module A into module B during testing. This results in the low-voltage wire, originally intended for temperature collection, being incorrectly connected to a voltage. This, in turn, causes a short circuit in the module after it is connected to the device's temperature acquisition module, damaging the sample and resulting in financial losses. Utility Model Content
