Battery Module Electrical Test Systems

Marposs  has combined its measurement experience and skills in automating complex systems into the development of battery module testing systems for electro-mobility applications. These solutions are capable of testing functionality, performance and electrical safety characteristics, as well as the logic management system.

These systems are available as semi-automatic solutions, where an operator manually joins the electrical connector to the battery module, or as fully automated applications where both the handling of the modules and the contact take place without human intervention.

These machines are used for the end-of-line test (Module EoL test) in the production of battery modules, as well as for beginning-of-line test (Pack BoL test), with possible Xion in classes, in the pack assembly lines.

Electrical Test Of Battery Modules
DESCRIPTION

Example of a Semi—Automated Battery Module Test Bench.

This very compact solution is designed for use as a stand-alone test station with manual loading or potentially assisted with mechanical aids. The connection and disconnection of the battery module to the test system is performed by the operator, with safety checks incorporated during the connecting of the electrical circuit. Additional safety measures include constant monitoring with a thermal camera of the battery module temperature when subjected to electrical operating load, and a fire prevention system connected to the factory network.

The test system features robust connectors, designed to withstand up to 100,000 operating cycles.

The electrical tests performed on the battery module include:

  • Insulation measurement and electrical rigidity test
  • Electrical continuity test
  • OCV control and comparison with internal measurement
  • ACIR and DCIR control, possible pulse power test
  • Functional check of the CMC or BMS
  • HVIL safety functionality check
  • Check of OCV homogeneity of the cells in the module and their temperature
  • Verification of the SOH and internal logic of the CMC
  • Measurement of module capacity (statistical check)
  • E9066 PC integrability for statistical control and control charts

This type of configuration is particularly suitable for use in pilot lines or in production lines for medium-low volumes. Pneumatic or helium leak testing of the module cooling circuit can also be integrated with the electrical test.

For mass production, Marposs offers various fully automated solutions.
