Battery pack and module testing is more critical than ever. Today’s engineers face new challenges including increased complexity of the tests and set-ups, long development and test times, addressing safety requirements, and avoiding hazards.
Module and pack tests typically evaluate the overall battery performance, safety, battery management systems (BMS), cooling systems, and internal heating characteristics. Common performance-based tests include drive-cycles, peak power capability, BMS software validation, and other application-specific characterization
This test plan defines a series of tests to behavior of a battery for electric vehicle battery modules, full-size battery packs or batteries in this plan). It may also be used subjected to the same or different test regimes Power, voltage, and current capabilities for specified. Special test equipment required for the individual test procedures.
There is significantly less time available to test during production due to high throughput. Typically the system validation done on the pack level can easily take upwards of 6 minutes per unit. For example, an EV battery manufacturer may plan to manufacture up to 40,000 or more battery packs a year.
