Basic introduction of charging pile interface

Compared with traditional fuel vehicles, electric vehicles have many advantages, but electric vehicles also have pain points, the speed of charging time, and the service life of the battery.

There are many discounts in the field of hybrid power, such as plug-ins, extended processes, etc. This does not require a large battery capacity. Compared with pure electric vehicles, the charging waiting time is shortened (and use gasoline/diesel to increase the mileage of battery life) Essence

Current electric vehicle technology has not made better charging time or battery life breakthroughs.

DC EV charger

As the saying goes, fish and bear’s paw cannot be both.

Because the life of the battery is related to the charging size, the greater the charging power multiplier, the smaller the number of cycles.

In order to ensure that the number of cyclic charging of the battery can be between 800 and 1000, the usual charging multiplier should be between 0.5°C and 0.25°C. Public facilities are exchanged charging piles.

In order to cope with the emergency, I hope that the battery can be fully fulfilled to 80%of the maximum capacity in a minute of 15-30 minutes. The corresponding charging rate should be between 2°C ~ and 4°C. This is a fast-charging solution. The supporting public facilities are DC fast EV charging piles Essence

DC EV charging piles are relatively damaged to batteries, and the cost the owner spent on replacing the battery will increase, so if it is not very urgent, you should minimize the use of DC charging piles.

The working principle of charging piles in the world is not much different, but there are different shapes, as follows:

Interface technology of AC EV charging pile

The exchange charging pile is relative to DC EV charging piles. The cost of exchange charging piles is low, the structure is simple, and the battery is more friendly.

The main function of an AC EV charging pile is to attract single-phase or three-phase electricity. The charging pile only plays the role of a current transit station. The subsequent rectification transformation is completed by the vehicle charger.

AC EV charging piles also have other commercial modules, such as human-computer interaction interfaces, billing modules, alarm modules, and control-guided circuits.

The control guidance circuit is the core content of AC charging pile interface technology, and in order to be compatible with both single-phase and three-phase electricity, GBT AC charging pile interface finally adopted the 7 terminal structure.

In addition, it is worth talking about the ChaoJi DC charging interface standard, which IEC unanimously approved in2022, The ChaoJi DC charging interface standard was initiated by China

The ChaoJi charging standard is expected to be the only global solution for next-generation DC charging technology.
