Problems solved by technology

[0003] Most of the existing electric vehicle charging piles use the traditional single Ethernet communication method, but most of the AC charging piles for slow charging are scattered, which makes it difficult or difficult to set up wired networks; the power of existing electric vehicle on-board chargers is not uniform, single The power specifications cannot meet the needs of various chargers, resulting in poor customer experience and slow charging

In order to improve the charging speed, the existing technology adopts the scheme of uniformly configuring high-power AC380V charging piles, but this method of uniformly configuring high-power AC380V charging piles is neither reliable nor safe, and the hidden danger of charging safety is great
