Nowadays, theworld is still relying heavily on fossil fuels such as oil and coal to meet its energy needs. Under the pressure of increasingly serious environmental problems, the change in energy structure has become an inevitable trend. The development of energy-efficient and new energy vehicles is an important part of this trend and has become a major consensus on the long-term development of automobiles. Under the active guidance of national policies, China’s new energy vehicle market has developed rapidly, with the market penetration rate growing from 0.3% in 2011 to over 4% in 2018. According to the goal proposed in the New Energy Vehicle Industry Development Plan (2021–2035), the sales volume of new energy vehicles will account for about 25% by 2025. Power battery is an important source of energy for newenergy vehicles, and its efficient and stable operation is the key to ensure the performance of newenergy vehicles. With the advantages of high energy density, high power density and long cycle life, lithium-ion batteries are currently the first choice for automotive power batteries. However, since the suitable working temperature range of lithium-ion batteries is relatively narrow (usually 10–30 °C), while the temperature range of new energy vehicles in application scenarios is much wider, the requirements for the adaptability of power batteries to high- and low-temperature environments are also more demanding with the widespread popularity of new energy vehicles. To solve the conflict between battery temperature characteristics and application requirements, battery thermal management requires tasks such as heat dissipation, heating and temperature difference control.
