Battery Test System - Test EV Battery Packs and Modules

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. EV battery teams must minimize cost while maximizing performance, and do so on aggressive timelines while ensuring the pack operates and fails safely every time, all the time, over the life of the vehicle and beyond.


  • 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.

NI Battery Test System (BTS)

  • The BTS Software Suite combines VeriStand and TestStand with plug-ins, device drivers, and analysis/test IP written specifically for battery test.

  • Built-in SystemLink™ software integration can manage a fleet of battery test systems and the data they produce over long-term tests.

  • The flexible and extensible measurement rack is based on reliable CompactRIO and modular C Series I/O.

  • In-chamber measurements are easy with rugged and daisy-chained FieldDAQ™ devices to decrease set-up times and reduce wiring.
