Description

technical field

[0001] The invention relates to the technical field of energy storage devices, in particular to a two-way management system for electric vehicle charging piles. Background technique

[0002] The concept of new energy is becoming more and more popular and the support of national policies for electric vehicles has made the sales of electric vehicles increase year by year. Electric vehicles have gradually replaced traditional vehicles and become the mainstream of the automotive industry. However, the increase in the use of electric vehicles has brought a number of problems:

[0003] 1. A large number of electric vehicles connected to the grid for charging at the same time will impact the distribution transformer of the community, resulting in an increase in the burden on the transformer, especially during the peak period of power consumption, which will seriously affect the distribution transformer of the community and shorten its life;

[0004] 2. The problem ...
