Industrial and commercial lithium battery module detection device

Abstract

The utility model discloses a kind of industrial and commercial storage lithium battery module detection devices, including PCB needle, with multiple detection channels, single detection channel has positive and negative pole circuit, and parallel light-emitting diode and Schottky diode, positive pole circuit is connected with light-emitting diode anode, negative pole circuit is connected with light-emitting diode cathode;Positive pole circuit is connected with Schottky diode cathode, negative pole circuit is connected with Schottky diode anode, and there is buzzer in series connection.Detection device is connected with measured module, under normal circumstances battery positive pole is connected with light-emitting diode anode battery cathode is connected with light-emitting diode cathode, light-emitting diode emits light, Schottky diode reverse cut-off buzzer no sound module CCS sampling normal.When battery module cell sequencing error, Schottky diode forward conduction, buzzer emits sound.Light-emitting diode reverse cut-off does not emit light.Buzzer no sound light-emitting diode does not emit light, show CCS sampling failure or module false soldering.
