Test all-in-one machine for battery module

Abstract

The invention discloses a test all-in-one machine for a battery module. The test all-in-one machine comprises an MES management system, an industrial personal computer connected with the MES management system, and a universal meter, an internal resistance instrument, a PLC module, a withstand voltage instrument and a communication system which are connected with the industrial personal computer through wires; the universal meter, the internal resistance instrument and the withstand voltage instrument are connected with the relay switching system. The output end of the relay switching system isconnected with a test interface used for being connected with a to-be-detected battery module, the test interface is connected with a probe pressing system, and the probe pressing system drives the test interface to do back-and-forth lifting movement. The relay switching system is connected with the PLC module; the PLC module collects test data of the universal meter, the internal resistance instrument and the withstand voltage instrument which are connected with the relay switching system, and uploads the test data to the industrial personal computer through the communication system, therebyimproving the detection efficiency of the battery module while achieving the matching of the upstream and downstream production capacities of equipment.

Description

technical field [0001] The invention relates to the field of battery module testing, in particular to an all-in-one battery module testing machine. Background technique [0002] At present, the power battery module has become the most critical part of the electric vehicle, the performance and safety of the power battery module will affect the mileage and safety of the electric vehicle. The detection process of the battery module is relatively complicated, and a series of tests such as open circuit voltage, wiring harness continuity detection, withstand voltage, and insulation need to be completed. In the traditional production line, each battery is generally tested manually using different equipment. The manual testing process takes a long time, and the test records of manual testing cannot be automatically saved, which affects the overall efficiency of the power battery module testing process. Contents of the invention [0003] In order to overcome the deficiencies of th...
