Cooling method of electric bus battery 2021-12-06

At present, the mainstream cooling systems for power batteries include air cooling and liquid cooling. The air-cooled battery box needs to extract air to conduct heat convection with the battery, and the protection level of the battery box cannot reach IP67. When the vehicle is wading or getting in the rain, there is a hidden danger of short circuit caused by water in the battery box. Therefore, the air-cooled heat dissipation method is not highly reliable and is gradually eliminated.

The liquid-cooled battery box uses coolant as the heat transfer medium to transfer heat to the battery through thermal diffusion. The protection level of the battery box can reach IP67 or higher. Therefore, the use of liquid cooling systems for power batteries has become the first choice for pure electric buses. The liquid-cooled battery box mainly includes a battery module, a water-cooled plate, a thermal conductive silicone grease, and a battery box. The battery module forms a thermal connection with the water-cooling plate through thermal conductive silicone grease, and the liquid-cooling plate is provided with water inlets and outlets that extend to the outside of the battery box.
