Battery pack wire sequence detection device

The utility model discloses a battery pack wire sequence detection device which comprises a plurality of light emitting diodes and a plurality of plug-in terminals. The LEDs are connected in series to form a series circuit; inserting terminals are connected to the two ends of the series circuit, inserting terminals are connected between the light-emitting diodes in the series circuit, and the inserting terminals are marked with a preset sequence according to the current direction of the series circuit; the preset sequence is used for prompting a user to sequentially plug the plug-in terminals of the battery pack according to the voltage from high to low and the current direction of the series circuit in a same-direction matching manner. According to the technical scheme provided by the utility model, the damage to the BMS control panel caused by the BMS test by using the battery pack due to the error of the battery line sequence can be avoided. 本实用新型公开了一种电池包线序检测装置，包括多个发光二极管和多个对插端子；各个发光二极管串联连接，形成串联电路；在串联电路的两端接
