3 Terms and definitions
The terms and definitions as defined in GB/T 18487.1-2015 and GB/T 29317-
2012 as well as the following terms and definitions apply to this document.
3.1
Conductive charging
The way in which the battery is charged by electrical conduction.
3.2
On-board charger
The dedicated device which is fixedly installed on an electric vehicle, to
convert AC power into DC power, to charge the power battery of electric
vehicle through conduction.
3.3
AC charging spot
A dedicated power supply device for providing AC power to an electric
vehicle which is equipped with an on-board charging device by means of
conduction.
3.4
5.5 By the level of output voltage
Charging spot are classified according to the level of output voltage:
- Single-phase AC charging spot;
- Three-phase AC charging spot.
6 Functional requirements
6.1 Charging control guidance
The charging spot shall have a charging control guidance function that complies
with the requirements of Appendix A of GB/T 18487.1-2015.
6.2 Communication function
The charging spot should have the function of communicating with the superior
monitoring management system.
6.3 Charging connection device
The charging connection device of the charging spot shall comply with the
provisions of GB/T 20234.1 and GB/T 20234.2.
6.4 Electronic locking device
For the charging spot which uses the connection method A or the connection
method B as specified in clause 3.1 of GB/T 18487.1-2015, then the rated
current of the charging spot is greater than 16 A, the power socket should be
equipped with an electronic locking device. When the electronic locking device
is not reliably locked, the charging spot shall stop charging or not start charging.
6.5 Human-computer interaction
6.5.1 Display function
The charging spot shall display the following status:
- The operating status indication of the charging spot: standby, charging,
failure.
The charging spot should display the following information:
- Output voltage, output current:
