Why do EV charging stations use AC charging piles?

What are the benefits?　　
The car charging pile adopts AC charging pile, mainly for the following reasons:　　
1, the first important is that the DC charging pile output of DC current is very large, hundreds of amperes, which has a great impact on the life of the battery, may lead to a lot of battery life reduction, and the current battery itself is the bottleneck of the development of electric vehicles (even including other devices, such as mobile phones and other electronic products). That is to say, the current battery technology itself is not very perfect, if the battery life is often lost, it is not economical enough.　　
2. AC 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, no need for rectifier device and other equipment, simple structure.　　
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, AC charging pile power is small, so the impact of electric vehicle charging on the power grid is also small, if the scale of electric vehicles in the future further increases, then if it is DC high power simultaneous charging, the pressure on the power grid will increase, of course, this is also a problem that must be considered in the future.　　
Therefore, if you do not need fast charging (direct current), it is recommended that you install a car charging pile in the choice above, try to choose an AC charging pile!　　
Electric vehicles will increase 10 times in the next 4 years, and by 2020, electric vehicles will account for more than 20% of car ownership
Charging Solution 1: Serving employees, providing charging services in the workplaceOur employees and potential employees are choosing electric vehicles as a means of mobility. Charging will become a popular work perk, happy for employees whether charged or not, and an important reference for young talents with strong values.
Charging solution 2 Low carbon environmental protection, encouraging employees to drive electric vehicles is a personal practice of energy conservation and environmental protection. In some cities, there is also a no-go policy. When employees consider whether to drive an electric car as a daily means of transportation, the first thing they think about is: I want to charge near the company.
