Battery module and pack testing involves very little testing of the internal chemical reactions of the individual cells. Module and pack tests typically evaluate the overall battery performance, safety, battery management systems (BMS), cooling systems, and internal heating characteristics.
We offer testing of battery products for use in a variety of motive or transportation-related applications. Through electrical, mechanical and environmental testing, we can evaluate the ability of large batteries to safely withstand simulated abuse conditions based on your specified charge and discharge parameters.
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
Key fundamentals of battery testing include understanding key terms such as state of charge (SOC); the battery management system (BMS) which has important functions including communication, safety and protection; and battery cycling (charge and discharge) which is the core of most tests.
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.
