At its Hybrid and Electric Vehicle Development Center, FEV offers the capability for hybrid vehicle development through lithium-ion (Li-ion) and nickel metal hydride (NiMH) battery testing. The company offers a comprehensive regimen of testing and validation to its customers, including testing in a climate chamber that can be operated from -30 to +85°C (-22 to +185°F). FEV can test batteries ranging from cells to modules to packs—both liquid and/or air-cooled systems. Battery management is a critical component for Li-ion battery systems. FEV offers the capability to conduct testing using either a client’s battery management system (BMS) or FEV’s internally developed BMS. Thus, validation of existing battery management systems is possible as well as testing of a battery with no BMS.
