Huang et al. [ 61] developed a thermal management control for electric vehicle power batteries using eddy current tube cooling and heating technology. The thermal management system converts the kinetic energy of the vehicle into air pressure by recovering the braking energy of the electric vehicle, which can provide energy for thermal management.
Awide-line metal film is proposed to heat the battery so as to meet the low-temperature operating requirements of the 8×8 wheeled electric vehicle. Experimental results prove that the wide-line metal film heating method can significantly improve the low-temperature performance of the battery. A diagram of the test platform is shown in Fig. 1.
The research results show that by pasting the electric heating film on the two sides of the battery, the battery temperature can be heated from −15 °C to 5 °C in 408 s, which is beneficial to shorten the preheating time and improve the temperature uniformity.
