Common charging protocols are protocols that define the compatibility between different electric vehicles and charging devices. The following are common charging public protocols:
< br >
1. CHAdeMO: This is an agreement jointly developed by Mitsubishi, Nissan and Fuji Heavy Industries in Japan. The agreement uses DC fast charging technology and is available for most electric vehicles made in Japan and South Korea.
< br >
2. CCS: CCS stands for Combined Charging System, also known as the European Fast Charging standard. It uses a plug connection, supports AC\/DC fast charging technology, and is suitable for most electric vehicles made in Europe, the United States and South Korea.
< br >
3. Tesla Supercharger: This is the charging technology and protocol developed by Tesla. It only applies to Tesla-branded electric vehicles.
< br >
4. GB\/T: GB\/T (National standard) is a fast charging standard issued by the Chinese government that uses plug connections, supports AC\/DC fast charging technology, and applies to most electric vehicles manufactured in China.
< br >
5. OCPP: The Open Charge Point Protocol (OCPP) is a network communication standard that connects and interacts with charging devices produced by different manufacturers. OCPP is an open protocol that facilitates the development of the charging industry and improves interoperability between charging stations.

In conclusion, there are some differences between the different charging public protocols, but they all aim to provide appropriate charging services for electric vehicles and ensure mutual compatibility.
Huawei's Fast Charge Protocol is divided into FCP (Fast Charge Protocol) and SCP (Super Charge Protocol). The former was used more in the early days and belongs to the high voltage fast charge school. It is now mainly based on SCP, and currently supports up to 40W, and only supports their own machines.
