Evaluation of Cold Temperature Performance of the JCS-VL41M PHEV Battery Using Battery HIL

摘要

Plug-in hybrid electric vehicles (PHEVs) have been identified as an effective technology to displace petroleum by drawing significant off- board energy from the electrical grid. A plug-in vehicle uses a large-capacity battery to operate in an electric-only or a blended mode of operation over a large SOC window (60-80% of total operational SOC) for maximum petroleum displacement. Some advanced chemistry batteries have shown that low ambient (battery) temperature has a significant impact on the performance of a PHEV battery. This paper quantifies the impact of low ambient (battery) temperature on a PHEV electric range using Hardware-in-the-Loop (HIL) methods. Combining ultra capacitors with batteries could provide a solution to overcome PHEV battery performance limitations at low temperatures.
