The electric vehicle (EV) battery pack—the single most costly EV component—also has the largest impact on performance (size, weight, acceleration, range, charge time, and vehicle life) so getting it right is critical to EV program success.
- Battery performance is highly temperature-dependent—thermal validation requires test in thermal chambers across operational temperature ranges.
- Battery performance degrades over time, and longevity testing is difficult to accelerate.
- EV battery packs are high-power devices requiring large, expensive battery cyclers to provide operational power levels during test.
- Rapidly evolving technology means constantly changing test requirements and managing a library of test equipment for a varied mix of battery designs.
