EV Powertrain Testing Solutions
Modular Solutions for Testing EV Powertrains
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. 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.
The best choice for powertrain testing is NHR’s next-generation battery emulation solution. It provides all of the following:
- 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 Products
NHR Battery Emulation Testing line includes the High Power Battery Test System (9200) and the High-Voltage Battery 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.
