The operating process involves the liquid (e.g., silicone oil) heated by the heater flows between the cells by employing the pump, facilitating the transfer of heat from the liquid to the battery. The inlet temperature, heating time, and external ambient temperature of the battery heating system all have an effect on the heat balance performance.
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 the rate of charge or discharge increases, the battery generates more heat energy. The battery's efficiency and longevity are negatively impacted by excessive heat. In cylindrical Li-ion batteries, the highest heat generation typically occurs at the center of the axis and then radiates outward to the cylinder's surface.
Ruan et al. constructed a low-temperature composite self-heating system, as shown in Fig. 46. This system integrated the internal DC heating of the battery and the external electromagnetic heating of the battery to improve the heating rate and efficiency without the need for an additional power supply.
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.
As mains gas is the only heating source for over two-thirds of UK households, switching to heat batteries can be transformational. However, not all heat batteries are created equal. While some are predominantly aimed at water heating, others are specifically designed for space heating. Different materials, different applications

Heat batteries can help balance the grid by completely decoupling energy consumption from heat demand – recharging only when demand is at its lowest, and releasing heat only when this is actually needed. In addition, they constantly monitor grid frequency and can stop charging in response to frequency drops.
