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.

まず、充電時にバッテリーと充電機器から発生する熱について分析しよう。充電時、バッテリー内部には一定の抵抗があり、充電時にはこの抵抗を通じて微量の熱が発生する。また、バッテリー内部の化学反応によっても熱が発生する。充電中、バッテリーは内部で充放電反応を起こし、発熱する。充電機器も電流や電圧の変化により発熱する。充電温度が高いため、充電機器まで破損することもある。

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

この空気は、新エネルギー車のバッテリーや充電ステーションの冷却に使用される。このソリューションの利点は、低コスト、設置やメンテナンスの容易さなどである。また、空冷は冷却剤を使用する必要がないため、環境に優しい。しかし、空冷の性能は液冷の性能より低く、液冷の高効率は達成できない。

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.
