Abstract

The invention relates to a battery module PACK large box assembly process detection system and its implementation method. The battery module PACK large box assembly process detection system includes a control computer connected to a multifunctional tester through a LAN. The invention accelerates the test speed , saves manpower, and saves the data of two tests at the same time, which is mutually verified; eliminates the error in the measurement process, avoids the randomness of human operation, improves the detection accuracy, reduces staff and increases efficiency.

Description

technical field [0001] The invention relates to a battery module PACK large box assembly process detection system, which belongs to the technical field of power batteries. Background technique [0002] At present, after the large box of the battery module PACK is connected, the installer needs to use a multimeter to check whether the wiring sequence is correct. The maximum voltage of a single cell is 3.7V. LUM is a management unit equipped with a large box to detect multiple strings of cells (generally 18-36 strings), but its input between adjacent lines cannot be higher than 5V. Before the data acquisition line is connected to the LMU of the large box, if the line sequence is wrong, the voltage between adjacent lines will be higher than 5V, which will damage the LMU. The voltage that the instrument can measure is ≤150V; [0003] Due to the large number of connections, the workload is heavy, errors are prone to occur during operation, and data recording is troublesome. Af...
