Electric Vehicles Test Solutions

NH Research (NHR) provides Electric Vehicle (EV) test equipment and software for individual components and systems including EV battery modules/packs, electric powertrain, DC fast chargers and EV power electronics.

With the accelerated growth of electric vehicles, engineers must address new testing challenges. Voltage and power levels are transitioning from a traditional 300/400VDC to 800/1000VDC. Higher voltages permit faster EV charging and increase power transfer while reducing vehicle weight. These factors are driving the development of higher performing EV batteries, electric drive-trains, power converters, inverters and faster chargers. Today’s EV test equipment needs to provide modular, scalable power, fast transients and integrated safety to address these changing test requirements.

Electric Powertrain Test Solutions

NHR’s battery emulation approach to testing the electric powertrain provides fast-transient speeds and accuracy to emulate real-world conditions for energy storage (battery) and wheel power. NHR’s 9300/9200 Battery Emulator accepts back EMF and prevents safety hazards. The isolated input and output paths eliminate single points of failure and unstable conditions. This highly modular and scalable  test solution meets current and future power requirements of electric powertrain systems.

DC Fast Charging Test Solutions

DC fast charging infrastructure now operates at higher voltage levels to accommodate faster charge times and larger electric vehicle batteries. Using batteries as power sources for testing fast charger systems is extremely time-consuming and costly. NHR’s bi-directional DC source can safely emulate an electric vehicle DC fast charger or a high voltage battery pack that can accept fast charging. The ability to emulate a wide range of vehicles, regardless of its battery characteristics and power levels, dramatically simplifies test. NHR’s unique battery emulation capability can substantially reduce test time, energy consumption and operating costs.

Utility Grid & V2G Test Solutions

Test the impacts of electric vehicles on the utility grid and vehicle-to-grid (V2G) technologies. Test equipment simulating the bidirectional power flows to and from the grid substantially speeds up test time and reduces energy costs. NHR’s 9410 Regenerative Grid Simulator is used to simulate the utility grid while NHR’s 9300 Bi-directional DC Source is used to emulate the EV battery, energy storage system, or fast charger. NHR’s 9430 AC Regenerative Load is used to simulate any inductive, capacitive or resistive load. This combination is an ideal test solution for IEEE 1547, UL 1741, and similar grid-tied standards as well as impact studies around the globe.
