Abstract: Apart from state of charge (SoC), which is normally considered while optimising energy management strategies for hybrid electric vehicles (HEVs), this paper has proposed additional consideration to effects caused by temperature. First, the vehicle model of plug-in hybrid electric sport utility vehicle (SUV) has been modelled by using Matlab/Simulink. Then, a supervisory controller has been built based on equivalent consumption minimisation strategy (ECMS). Next, fuzzy logic controller has been designed to control the usage of the battery due to two factors: the temperature and the SoC. Finally, simulation tests are conducted under New Europe Driving Cycle (NEDC). According to the battery characteristics, the proposed strategy can penalise the usage of the battery at lower temperature and encourage it when temperature gets higher. Compared to strategies without consideration to temperature, such considerations are in line with the actual situation, especially when the temperature is really low or the trip is long.
