We are now very advocating new energy life. There are various new energy products, and the use of new energy vehicles is now very large. When talking about the current big fire of new energy vehicles, users always hear the words DC charging and AC charging. What's the difference between these two charging methods? Next, Guodian Technology New Energy will introduce two national standard charging pile interfaces - AC charging pile interface and DC charging pile interface, and introduce relevant interface technologies around commonly used AC charging interfaces. Do not miss friends who want to know!

However, in the field of pure electric vehicles, it is difficult to unilaterally optimize the charging time or battery life. You can't have both fish and bear's paw, because the battery life is related to the size of the charging rate. Generally, the larger the charging and discharging rate, the smaller the number of cycles.

In order to ensure that the cycle charging times of the battery can be between 800~1000, the charging rate should generally be between 0.5C~0.25C. The national grid is used for power supply, and the on-board charger is used to charge the power battery. This is a slow charging scheme, and the supporting public facilities are AC charging piles. If you want to quickly charge the battery to 80% of the large capacity, the corresponding charging rate should be between 2C~4C. This is a fast charging scheme, and the supporting public facilities are DC charging piles.

The main function of AC charging pile (including national standard and non national standard) is to lead out single-phase electricity or three-phase electricity. The charging pile only acts as a current transfer station, and the subsequent rectification+DC/DC conversion is completed by the on-board charger. The national standard AC charging pile is to add some commercial modules (such as human-computer interface, billing module, alarm module, etc.) and control guidance circuit on the basis of the original AC charging pile shown in the above figure. The control guidance circuit is the core content of the AC charging pile interface technology. In order to be compatible with single-phase and three-phase electricity, the national standard AC charging pile interface finally adopts the 7-terminal structure.

That's all for the charging pile interface. We will update the news about this regularly. If you have any questions, please follow us!
