Battery pack detection system

The utility model discloses a battery pack detection system, which can directly take electricity from the output end of a battery pack through a BUCK power supply so as to directly supply power to a high-voltage detection system without taking electricity from a control box, thereby simplifying a power supply mechanism. And meanwhile, the working current and the working voltage of the battery pack can be continuously detected through the running state detection unit, so that when the current and the voltage are abnormal, the fusing control module is actively controlled to drive the fuse to complete fusing, and the safety of the vehicle is ensured. Besides, independent detection of various signals collected by the operation state detection unit and control of the fusing control module are realized through the core controller, a main control box is not needed to assist in detection, the main control box only needs to interact with the battery pack detection system to obtain detection signals, and the detection
