Cooling Systems for Battery Charging Stations

With the development of the automobile industry, the market share of new energy vehicles continues to rise. These new energy vehicles include pure electric vehicles, hybrid vehicles, etc. For the use of these vehicles, charging is a very important link. As charging proceeds, both the battery and the charging device will generate a lot of heat. This requires an effective solution to provide cooling systems for new energy vehicle battery charging stations.

먼저 충전 중 배터리와 충전 장비에서 발생하는 열을 분석해 보겠습니다. 충전 시 배터리 내부에는 일정한 저항이 존재하며, 충전 중에는 이러한 저항을 통해 소량의 열이 발생합니다. 또한 배터리 내부의 화학 반응도 열을 발생시킵니다. 충전 과정에서 배터리는 내부 충전 및 방전 반응을 거치면서 열이 발생합니다. 충전 장비도 전류와 전압의 변화로 인해 열을 발생시킵니다. 때로는 높은 충전 온도로 인해 충전 장비가 손상되기도 합니다.

Next, let’s take a look at the cooling solutions for new energy vehicle battery charging stations, which are divided into the following two types:

1. Air cooling solution

이 공기는 새로운 에너지 차량 배터리와 충전소를 냉각하는 데 사용됩니다. 이 솔루션의 장점은 저렴한 비용, 간편한 설치 및 유지보수 등입니다. 또한 공랭식은 냉각수를 사용할 필요가 없으므로 환경 친화적입니다. 하지만 공랭식 냉각의 성능은 액체 냉각보다 낮고 액체 냉각의 고효율을 달성할 수 없다는 단점이 있습니다.

2. Liquid cooling solution

In this solution, liquid is used to cool new energy vehicle battery charging stations. Liquid cooling solutions typically use coolants such as water and glycol mixtures. Liquid cooling systems can provide higher cooling efficiency because liquid cooling has a greater heat capacity than air cooling. Additionally, the liquid cooling system can be adjusted as needed for optimal cooling. However, the disadvantages of liquid cooling solutions are that they are more expensive and require more complex installation and maintenance.

In addition to the above two solutions, there is also a hybrid solution. For this scheme, air cooling and liquid cooling are usually combined. In this hybrid solution, the heat in the battery and charging equipment that is cooled by air cooling is often sent to the liquid cooling system for further cooling.

For different new energy vehicle charging systems, we can use different cooling solutions. For example, a system that uses water cooling mode can better reduce the temperature of the battery, thus extending its service life. At the same time, it will also provide better protection for high-speed charging and long-term driving of new energy vehicles.

All in all, cooling solutions for new energy vehicle battery charging stations are very important, as they can extend the service life of batteries and charging equipment, improve charging efficiency, and avoid damage caused by overheating. In the future, with the continuous advancement and innovation of technology, we believe that more and more efficient charging and cooling technologies will be applied to the field of new energy vehicles.
