Why do new energy vehicle charging piles use AC charging piles?

Latest company news about Why do new energy vehicle charging piles use AC charging piles?

Why do the current new energy vehicle charging piles mainly use AC charging piles?

 

There are mainly the following reasons:

 

1. I think the most important thing is that the DC power output from the DC integrated charging pile is very large, hundreds of amps, which has a great impact on the life of the battery and may lead to a lot of reduction in the life of the battery. At present, the battery itself is the development of electric vehicles (even Including other equipment, such as mobile phones and other electronic products) bottlenecks. In other words, the current battery technology itself is not very perfect, if the battery life is often depleted, it is not economical enough.

 

2. The electric vehicle charging pile is convenient. It is installed in the parking lot or charging station. The input side only needs to be connected from the power grid. The output is also AC, and other equipment such as rectifiers are not required. The structure is simple.

 

3. Extending from the battery, the current electric vehicle is not suitable for long-distance driving, so in most cases, the electric vehicle can be charged slowly at work or at home at night.

 

4. The power of the AC charging pile is small, so the impact of electric vehicle charging on the power grid is also small. If the scale of electric vehicles is further increased in the future, if the DC high power is charged at the same time, the pressure on the power grid will increase. Of course, this It is also an issue that must be considered in the future.
