Electric Vehicles Traction Battery Testing
EV/HEV Battery Test Equipment
Traction batteries are used to provide power for electric vehicles (ev) and hybrid-electric vehicles (hev). Typical applications for EV/HEV and Traction Batteries are power for fork lifts and electric carts. The primary emphasis on traction battery design is the need for a high capacity (weight to volume ratio) since the vehicle will be carrying its own power source. Other factors include deep cycling, reasonable charging time (usually within 24 hours) and battery cost.
EV/HEV and Traction Battery testing ensures that the battery and design meets the requirements for the application. NH Research, Inc. (NHR) manufactures battery test system solutions and dc electronic loads that simplify testing, reducing man hours and labor costs.
NHR’s high-voltage, Electric Vehicle battery test equipment is designed for electric vehicle battery modules and battery pack level testing. Demands for higher-performing electric batteries require the appropriate battery test equipment to evaluate options safely, efficiently and effectively. NHR’s advanced features include regenerative power-cycling that reduces waste heat by returning energy back into the system or grid. NHR’s 9200/9300 Battery Pack Test Systems are modular with flexible configurability to expand with additional power modules as needed. Unlike traditional battery simulator technologies, NHR’s battery emulator has advanced capabilities that simplifies EV battery test and can help accelerate time to market by physically emulating a real battery and eliminating the risks and costs associated with testing real batteries.

Battery Test Systems & DC Electronic Loads
Electric Vehicles Battery Test Equipment
There are two types of test equipment for battery test.
The 9200 Series Battery Test System consists of bi-directional, regenerative DC power modules with voltages of 40, 120 or 600V. Capable of charge/discharge and cycle testing of 10 – 250kW module and pack-level batteries, this highly flexible system can be integrated into an existing software environment, run from a PC with NHR’s Enerchron® Test Manager or locally through a touch-panel located on the 9200 cabinet.
The High-Current DC Electronic Load (120V) 4700 Series and High-Voltage DC Electronic Load (600V) 4760 Series air-cooled dc loads can be used in applications where discharge only is needed. These loads can be controlled either through LabVIEW or NHR’s Enerchron® Test Manager.
