Abstract

The invention discloses a power pack testing system which comprises the components of a process controller, an insulated withstand voltage tester, a charging / discharging tester, a CAN conversion card, BMS testing equipment, an NDAM data acquisition system, a single inspection device and a scanning gun. The process controller is connected with the charging / discharging tester through a DSRAM interface. The process controller is connected with the insulated withstand voltage tester and the scanning gun through an RS485 port. The process controller is connected with the BMS testing equipment through an external CAN port. The process controller is connected with the CAN conversion card, the NDAM data acquisition system and the single inspection device through an Ethernet port. The power pack testing system realizes multiple functions of power pack insulation testing, BMS checking, DCR testing, OCV testing, etc. In an equipment integration manner, full intelligence and full automation of the whole Pack production testing process are realized, thereby maximally reducing manual operation, greatly improving power pack testing efficiency and reducing testing cost.

Description

Technical field [0001] The invention belongs to the technical field of power battery testing, and specifically relates to a power battery Pack testing system. Background technique [0002] In the process of power battery testing, power battery manufacturers generally use battery charging and discharging testers to perform charging and discharging tests on Pack (package) battery packs to complete the formation, and then use independent insulation monitoring equipment to test the battery insulation voltage; use CAN The bus test software and tools send test instructions to control the relevant relays and communication frames to complete the verification test of the BMS (battery management system) that comes with the Pack battery pack to determine whether it is qualified; in addition, the standard single unit inspection is required The battery cell voltage data collected by the equipment and the cell voltage data collected by the BMS are tested for accuracy comparison; in addition, t...
