Charging and switching facility standards are developed and published by the "Technical Committee for Standardization of Electric Vehicle Charging Facilities", which was established in June 2010, with the secretariat located at the China Electricity Corporation Federation and the competent unit: National Energy Administration.
The dimensions of the overall charging and switching facilities standards are as follows
1. electrical energy replenishment: conduction charging, wireless charging, power exchange.
2. service network: charging and switching stations, service network.
3. Construction and operation: metering, power quality, interaction with power grid, operation management, construction acceptance.
The following standards have been published.
1. Charging interface and communication protocol standards: 2011 version of the national standard, 2015 version of the national standard
2. Charging facility key equipment standards: DC charger, vehicle charger, charging equipment inspection specifications, etc.
3. Charging station construction standards
4. Power exchange standards (Design Specifications for Electric Vehicle Battery Replacement Stations (GB/T51077-2015))
5. Charging facility operation and maintenance standards
The charging technology standards that will be announced in the future are
High power charging standard: expected to be announced around 2020
Wireless charging technology standards: expected to complete the promotion of relevant standards after 2020
There are many other charging standards, such as smart grid interaction standards, power exchange standards, DC high power/low power, plug-and-charge, etc., which will not be repeated here.
Regarding the battery management system, the state has published GB/T27930-2015 communication protocol between non-vehicle conductive charger and battery management system for electric vehicles, which is shown in the table of contents below.
Electric vehicle charging and swapping want to have an orderly development, standards must be established so as not to cause waste of resources.
