Battery pack current detection control system and battery pack system comprising same

Abstract

The invention discloses a battery pack current detection control system and a battery pack system comprising the same. The battery pack current detection control system comprises a current sensing module and a fusing device, the current sensing module comprises a current acquisition unit which is used for being connected in series between a positive electrode and a negative electrode of a battery pack so as to acquire current data of a battery main loop in real time; the comparison unit is respectively connected with the current acquisition unit and the fusing device and is used for receiving the current data acquired by the current acquisition unit and comparing the current data with a preset current threshold value, and when the current data exceeds the preset current threshold value, the comparison unit generates a first circuit breaking signal and directly outputs the first circuit breaking signal to the fusing device; therefore, the fusing device disconnects the battery main loop. The current detection control time can be shortened, the fusing device is triggered in time, the short-circuit current is quickly cut off, and the safety of the battery is improved.
