Abstract: The integrated thermal management system (ITMS) can effectively improve the pure electric range of the vehicle. This work proposes a ITMS based on a super bottle. In this work, the power battery temperature is subdivided into five stages and a control strategy for heating the battery and cabin with dual heat sources in a low-temperature environment is developed. Then a numerical integrated simulation model of the ITMS is developed and experimentally verified in an environmental chamber . The experimental and simulation conditions used throughout the study are set to an ambient temperature of 0 °C. At the same time, due to the better sampling of data under 40 km/h, a constant speed of 40 km/h is used. At 0 °C, through 660 s of 40 km/h conditions, the results show that the ITMS can heat the battery to 15 °C in about 20 min at a low temperature of 0 °C, and heat the cabin to 22 °C in 10 min. The ITMS also improves battery warm-up efficiency by 16.7 % and reduces energy consumption by 5.5 % compared to the original system. The ITMS is 17 % more expensive than the original system. In addition, the low-temperature electric range has been increased by 3.3 km, and the cost of increasing the range by integrating the thermal management components is approximately 28 ¥/km.
