The battery electric vehicle (BEV) has the potential to decarbonise the transport sector through the use of renewable electricity and zero tailpipe emissions, however, limited vehicle range remains a significant issue. This is especially true in cold climates where batteries become less efficient and available capacity is reduced.Furthermore, conventional lithium-ion batteries cannot charge at low temperatures due to the risk of lithium plating and short-circuiting. This project will research methods of battery operation strategies to maximise the range available in a BEV when starting at sub-zero temperatures. This may include combinations of self-heating through discharge, external heaters and additional energy storage devices. The methodology could apply equally to electric road vehicles or high-altitude unmanned aircraft.
