New energy vehicle charging piles ensure charging safety and provide strong support for big data mining and extraction, promoting the interconnection and intelligent services of China's charging facilities. At the same time, through the mobile phone APP, users can enjoy convenient charging services, check the location, status and other information of the charging pile in real time, and easily complete charging reservations.

Why do new energy vehicles use AC charging piles at present?

1. I think the most important thing is that the DC power output of the DC charging pile is very large, hundreds of amperes, which has a great impact on the service life of the battery, and may cause the battery life to be greatly reduced. At present, the battery itself is the short board of the development of electric vehicles (even including other equipment, such as mobile phones and other electronic devices). In other words, today's new batteries themselves are not very sound. If the battery life is often consumed, it will not be economical.

2. The AC charging pile is convenient. It is installed in the parking lot or electric vehicle charging station. The input side only needs to be connected from the power grid. The output is also AC, and no other equipment such as rectifier equipment is required. The structure is simple.

3. From the perspective of battery expansion, current electric vehicles are not suitable for long-distance driving, so in most cases, electric vehicles can be charged slowly at work or at home at night.

4. The output power of AC charging piles is small, so the impact of electric vehicle charging on the power grid is also small. If the scale of electric vehicles is further expanded in the future, then if the DC power is large and charging at the same time, the pressure on the power grid will increase. Of course, this is also a problem that must be considered in the future.
