NB/T 11305.2-2023Electric vehicle charging and discharging bi-directional interaction - Part 2: Coordinated Charging (English PDF)

3.1 coordinated charging

charging electric vehicle according to certain strategies via guidance and coordination with economic or technical measures

3.2 coordinated charging equipment

charging equipment with the function of executing a coordinated charging control strategy

3.3 coordinated charging management system

system that realizes the formulation, distribution, monitoring and management functions of coordinated charging control strategy between electric vehicles and power grids or other main bodies

3.4 coordinated charging management terminal

special device with the functions of remote reception, local generation and distribution and execution of coordinated charging control strategy, which realizes the local operation and management of coordinated charging equipment

3.5 coordinated charging control unit

control unit with the function of receiving and executing a coordinated charging control strategy

4.1 System architecture

The coordinated charging system of electric vehicles is an integral part of the bi-directional interaction architecture of electric vehicles, which may include coordinated charging equipment (including charging equipment equipped with coordinated charging control unit), coordinated charging management system, coordinated charging management terminal, etc. See Annex A for the system architecture block diagram, which may be selected according to the application scenarios:

a) The coordinated charging equipment is directly connected to the independent coordinated charging management system, the system architecture diagram shown in Annex A.1;
