Fig. 21. (a) Photograph of the battery pack and heater, and (b) photograph of the battery box inside the thermostatic enclosure . To reduce the energy consumption of batteries during the heating process of EVs, researchers have proposed burner heating methods that utilize alternative energy sources.
For the embedded heating elements, Wang et al. embedded nickel foil inside the battery and utilized the heat generated by the nickel foil to heat the battery. Although this method can heat the battery from −20 °C to 0 °C in 20 s, it requires a redesign of the battery structure and the effect on battery safety is not clear.
As dynamic energy tariffs evolve, heat batteries will be able to meet the higher heat demand of larger houses without increasing their footprint – or even reducing it. This evolution will involve charging flexibly throughout the day rather than in a single overnight period typically seen in existing smart tariffs.
Then, in this section, the thermal management scheme of automotive batteries will be built based on the principle of battery heat generation and combined with the working principle of new energy vehicle batteries. New energy vehicles rely on batteries as their primary power sources.
Since the batteries in the battery pack will generate a lot of heat during operation, the performance of the battery pack will be severely affected. As a result, new energy vehicles are increasingly being developed with a focus on enhancing the rapid and uniform heat dissipation of the battery pack during charging and discharging.
The battery heats the evaporation section of the heat pipe, and the liquid inside the pipe core evaporates to steam as a result. During condensing, the steam releases latent heat and returns to liquid, which passes through the central channel of the heat pipe.
In its journey, the fluid absorbs heat during battery operation and charging processes. Subsequently, it transports this heat away from the battery cells and through a heat …
