Electric Vehicle Powertrain Test Solutions

Modular EV Test Solutions for Powertrain Testing

NHR is a leading provider of automotive and Electric Vehicles (EV) test solutions and EV battery test equipment. EV test applications include EV powertrain testing,  EV battery testing (modules, battery packs, fuel cells),  DC Fast Charger testing, and  EV power electronics components testing including on board chargers and inverters.

As the electrification of the automobile continues to accelerate, automotive engineers must address new testing challenges for powertrains of Battery Electric Vehicles (BEV) that did not exist with traditional powertrains. The Powertrain includes both the motor and the drivetrain that delivers power to the vehicle’s wheels.  Voltage and power levels are changing due to fast charging and vehicle performance. Power and voltage levels are transitioning from a traditional 300/400VDC level toward 800/1000VDC. Higher voltages permit faster charging and increase power transfer while reducing vehicle weight. Traditional powertrain test approaches rely on unidirectional devices that have drawbacks and limitations. Modern battery emulation is a bidirectional approach that is isolated, can handle back-EMF, and is a more robust topology than a traditional battery simulator.

The best choice for EV powertrain testing is NHR’s next-generation battery emulation test solution, also known as NHR’s Battery Test Systems. The 9300/9200 Battery Test Systems also serve as a battery emulator. Unlike traditional battery simulator technologies, NHR’s next-gen battery emulation technology can be used to emulate a high voltage battery for EV Powertrain testing.

  • Flexibility to address changing voltage needs
  • Scalability to address future power levels
  • A series resistance model to simulate a battery more accurately
  • Faster response times than DC power supplies
  • Easier integration and software control
  • Reduced energy costs

Battery Test & Battery Emulation Systems

ev powertrain testing - battery test system 9200 seriesNHR Battery Emulation Testing Equipment includes the High Power Battery Test System (9200) and the High-Voltage Battery Pack Test System (9300) series. NHR’s Battery Emulation products are designed to emulate a battery rather than using a real battery. The emulated battery dramatically reduces testing time, provides highly repeatable test results, and creates a safer test environment. Also, preparation time, operator errors, and result variations due to battery temperature or aging, are eliminated.
