6 FAQs about [Principle of new energy battery active heater]

How does a power battery heater work?

The principle is that when the power battery discharges, the current flows through the heating element to generate heat to heat the surrounding air, and the hot air is conveyed to the battery pack by the fan, to achieve the purpose of heating the battery. Its schematic diagram is shown in Figure 7. Figure 7.

How to conduct heat efficiently in a battery module?

To conduct the heat efficiently, the heat spreaders may be placed between batteries to enhance the heat transfer from the module to the cold plates. Because of the flat shape, the cold plates are widely used in battery module, consisting of prismatic cells instead of cylindrical cells.

What happens when a battery is ventilated in series?

When ventilating in series, the air enters the ventilation duct and flows over the surface of the battery in turn, during the flow, the temperature of the air gradually increases, and the temperature difference between the air and the battery continues to shrink, resulting in the uneven temperature of the battery pack.

Can electric heating film be used to heat a battery?

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.

How does a battery heat a heat pipe?

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.

How a heat pipe can reduce the temperature of a battery?
