Power Capability Testing of a Lithium-ion Battery Using Hardware in the Loop (2010-01-1073)

The energy storage system (ESS) is the key enabler to hybrid electric vehicles (HEVs) that offer improved fuel economy and reduced vehicle emissions. The power capability of a battery has significant impact on the fuel economy of HEVs.
This paper presents the power capability testing of a lithiumion battery with a conventional metal oxide cathode using the hardware in the loop (HIL) at a wide range of charge/ discharge conditions and at different temperatures. The achieved test results provide critical data of battery power characteristics and effectively accelerate the development of battery power prediction algorithm.
