: V2G charging pile overall solution

Provide a total charging pile solution that meets all conditions and requirements of V2G (vehicle network interaction through charge and discharge), including a complete set of controllers required for a complete charging pile. Only need to provide the solution to the factory, you can produce V2G charging pile that can adapt to national and overseas standards.

01

CCU

Dc control unit is the controller developed by our company for DC charging pile, the working voltage is 12V.

The motherboard completes the interaction with the BMS, sends the charging demand to the charger, controls the charging state of the charger, collects the operating data of the charger, and stops automatically under abnormal state;
Dc charger control unit with charging gun electric lock control and temperature detection, each charging gun detection and control work independently.
02

SECC

After installing the charging pile conforming to GB/T27930, the international DC charging pile can be transformed into charging pile equipment conforming to DIN70121&ISO15118; Or the charging pile control board is not converted through the national standard agreement, and is directly implemented as follows:

Chademo protocol
CCS1（SAE J1172)
CCS2（DIN70121&ISO15118）
03

WEBBOX

In order to realize the function of the cloud platform remote control of the charging pile: control the start and stop of the charging pile through the mobile phone, remote access to the daily charging times of the charging pile, charging model, charging success, charging capacity and other information. Our company specially designed the WEBBOX controller to help realize the docking of charging pile and cloud platform, which is used to receive the command issued by the cloud platform and report the data to the cloud platform in time. Its basic functions are:

l WEBBOX connects to the cloud server through 4G module, Ethernet and WIFI;
l WEBBOX interacts with the CCU and screen at the end of the charging pile;
The interaction between the WEBBOX and the CCU (the charging pile is charged through the CCU control) is as follows: The WEBBOX sends charging instructions to the CCU, and the CCU returns charging quantity and charging status information to the WEBBOX.
In general, WEBBOX is the external window of the internal controller of the charging pile, and all interactions between the charging pile and the OCPP cloud platform need to be carried out through WEBBOX.

: Charging pile protocol conversion technology

Transform the international DC charging pile into the charging pile equipment conforming to DIN70121& ISO15118; Or the charging pile control board does not convert through the national standard agreement, and directly realizes the following agreement:

Chademo protocol
CCS1 (SAE J1172)
CCS2 (DIN70121&ISO15118 Supply Electronic Charging Controller)
