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.

First, let’s look at the heat generated by batteries and charging equipment when charging. When charging, there is a certain resistance inside the battery, and a small amount of heat is generated through these resistances during charging. In addition, chemical reactions inside the battery also generate heat. During the charging process, the battery will undergo internal charge and discharge reactions, resulting in the generation of heat. Charging equipment also generates heat due to changes in current and voltage. Sometimes the charging equipment may even be damaged due to excessive charging temperature.

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

In this solution, air is used to cool new energy vehicle battery charging stations. Advantages of this solution include low cost, ease of installation and maintenance. Additionally, air cooling is environmentally friendly as it does not require the use of any coolant. However, the performance of air cooling is lower than that of liquid cooling and cannot achieve the high efficiency of liquid cooling.

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.
