How to choose distribution transformer for electric vehicle charging station

Many cities are now planning to build car charging stations, and some cities may have developed faster. Speaking of the function of the car charging station, in fact, the role of the car with the gas station is similar, the difference is that the two different service targets, electric car charging station is to charge the charging point to provide electric car for charging services.

It is easy to see that as the popularity of electric vehicles and the increase in the number of electric vehicles, the number of car charging stations will surely increase, and further, the demand for electricity will also be large. So for the car charging station, the core component system is the distribution system. Then, how do distribution transformers in critical power distribution systems be selected?

First, the choice of transformer type

We need to comply with this choice in accordance with the actual needs, that is, the size of the car charging station and the amount of electric energy needed, so as to select the most suitable distribution transformer. The general charging station is mainly used SC dry-type transformers. Stable performance and energy saving and environmental protection.

Second, the choice of the number of transformers

That is, the number of transformers to be used is selected. According to the size of the charging station and the distribution rate of the car users, an appropriate number of transformers is selected. Make each transformer can be used, no idle situation will not occur, but also to avoid the waste of resources.

Third, the choice of transformer wiring

Simply speaking, it is the choice of the most suitable wiring for each transformer. In everyday life, most automotive charging stations use appropriate wiring depending on the nature of the transformer, function, etc., and Dynll wiring is mainly used because Dynll wiring is the most suitable wiring for transformers.

Having said so much, through the above introduction, we must have a clear understanding of the choice of transformers, and now the popularity of car charging stations is not very clear, but with the rapid development of electric vehicles, the market share continues to increase. We believe that this knowledge will help us in the future.
