GB/T 19596-2017 Terminology of electric vehicles
3 Terms and definitions
3.1
Traction battery; propulsion battery
A battery, that provides energy for the power system of an electric vehicle. [GB/T 19596-2017, Definition 3.3.1.1.1.1]
3.2
Charging and discharging infrastructure
Infrastructures that can provide charging and discharging services, at the same time, for power batteries of electric vehicle.
Note: It is mainly composed of electric vehicle charging and discharging equipments, related power supply equipment, monitoring equipment, other auxiliary equipment.
3.3
Charging and discharging operation and management system
A system, which realizes the data collection, data storage, statistical analysis, operation decision-making, business service, dispatching management of
electric vehicle charging and discharging related businesses.
3.4
Charging and discharging equipment
An equipment, that is connected between an electric vehicle or a traction battery and the grid (or load), to achieve two-way flow of energy.
Note: Generally, it includes off-board charging and discharging equipments, on- board charging and discharging equipments, AC charging and discharging spots. 3.4.1
Off-board charging and discharging equipment
A dedicated equipment, which is installed outside of the electric vehicle; can realize the two-way conversion BETWEEN the AC power of the grid AND the DC power of the electric vehicle; adopts the conduction method for charging and discharging the traction battery of electric vehicles.
3.4.2
On-board charging and discharging equipment
A dedicated equipment, which is installed on the electric vehicle; can realize the two-way conversion BETWEEN the AC power of the grid AND the DC
power of the electric vehicle; adopts the conduction method for charging and discharging the traction battery of electric vehicles.
3.4.3
AC charging and discharging spot
An equipment, which uses a conduction method to provide a two-way flow
of energy, BETWEEN an electric vehicle with an on-board charging and
discharging equipment AND the power grid.
3.5
Connection set for charging and discharging
The components that, when charging and discharging electric vehicles,
