Outline
With the continued expansion of the pure electric vehicle market, it is necessary to optimize the overall thermal management control strategy for BEVs in low temperatures. The optimization is crucial to better suit the application scenarios, particularly to meet the growing demands of customers in northern cold regions and to alleviate the decline in driving range of BEVs in lowtemperature environments. Based on research and realvehicle validation of the thermal management control strategies for waste heat source heat pumps and air source heat pumps in different lowtemperature scenarios for a BEV model, the paper has extended the effective operating lower temperature limit of the heat pumpbased thermal management system from 15 °C to 20 °C. Moreover, the attenuation rate of driving range has been significantly reduced to 31.2% under the CLTC driving condition at 7 °C.
