A traction battery pack has a basic modular structure. Several battery cells form a battery module, and several modules together with the battery management system (BMS) form the battery pack. The BMS is responsible for the safety and performance of a battery pack. For example, it must read the voltages and temperatures of the cell stack and the inputs from the associated temperature, current, and voltage sensors. It must process the inputs, and make logical decisions to perform cell balancing. In addition, the BMS is also responsible for optimal DC fast charging.
The development of new traction batteries requires extensive testing and validation with respect to their specified application. Performing safety, life cycle, and abuse tests, this process includes testing the design and materials used in the battery, as well as the effects of the environment on the battery.
In the webinar, we will show test solutions for electrical, mechanical, and thermal testing of cells, modules, and battery packs. Additionally, we will present battery management system testing and protection type testing against water jets.
- Examples of electrical, mechanical, and thermal testing of battery cells, modules, and whole packs.
- Test setup for battery management systems
- Protection class tests for jet water, surge water, and high pressure
