2. Normative References
The following documents are essential for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest editions
of the normative documents (including all the amendments) are applicable to this
document.
GB/T 20234.1-2011 Connection Set for Conductive Charging of Electric Vehicles
- Part 1. General Requirements
3 Term and Definition
The terms and definitions of GB/T 20234.1-2011 are applicable to this document.
4 General Requirement
The technical requirements and test methods of DC charging couplers shall meet the
requirements of GB/T 20234.1-2011.
5 Rated Value of DC Charging
The rated values of DC charging couplers are detailed in Table 1.
A.2 Operation and control procedure in charging process
A.2.1 The vehicle plug and the vehicle socket-outlet shall be connected with each
other to put the vehicle into a non-driving state.
The vehicle plug and socket-outlet shall be connected with each other. The vehicle
overall design plan may auto-start some triggering conditions (such as open the
charging door, connect the vehicle plug and socket-outlet or conduct function
triggering on charge buttons or switches, etc.). Through interlocking or other control
measures, vehicles are put into a non-driving state.
A.2.2 The arrangement of man machine interaction during charging. the complete
connection state of the vehicle coupler is confirmed by the control device (state 3)
After the charging of a non-on-board charger has been set by operators, the control
device of the non-on-board charger shall judge the complete connection state
between the vehicle plug and the socket-outlet through measuring the voltage of
inspection point 1. For example, if the voltage of inspection point 1 is 4V, the vehicle
coupler is judged as “completely connected”. After the man machine interaction of a
charger has been set by operators, and the vehicle coupler has been judged by the
non-on-board charger as “completely connected”, the non-on-board shall control the
locking of the electronic lock. During the whole charging process, only when the
command to stop charging is set for the non-on-board charger by the operators, the
electronic lock maybe unlocked.
A.2.3 Completion of non-on-board charger's self-checking (state 4)
If the non-on-board charger completes self-checking after complete connection of the
vehicle coupler, then contactor K3 and K4 will be closed, so as to turn on the
conduction of the low-voltage auxiliary power supply loop-circuit. Simultaneously, the
transmission of "charger identification message" shall begin periodically. After
obtaining the power supply of the low-voltage auxiliary power provided by the
non-on-board charger, the vehicle control device shall judge whether the vehicle
coupler has been completely connected through measuring the voltage of inspection
point 2. If the voltage of inspection point 2 is 6V, the vehicle control device will begin to
sent "vehicle control device (or battery management system) identification message"
periodically. The signal may also be served as one of the triggering conditions for the
vehicles to enter a non-driving state.
A.2.4 Charging in train (state 5)
After the vehicle control device and the control device of the non-on-board charger
have completed handshake and configuration phases through communication, then
vehicle control device will close contactors K5 and K6 to conduct the charging
loop-circuit; the control device of the non-on-board charger will close contactors K1
and K2 to conduct the DC loop-circuit.
A.2.7.4 During charging process, the control device of the non-on-board charger
detects the voltage at Inspection Point 1; if switch S is judged as “turn to the CLOSE
state from OPEN state (State 7), and it persistently maintains for a certain time (e.g.
300ms), then control the charger to stop charging; and contactors K1, K2, K3 and K4
will be disconnected.
A.2.7.5 During charging process, the non-on-board charger detects the voltage at
Inspection Point 1. If the vehicle coupler is judged as “turns to OPEN state (State 8)
from complete connection”, then control the charger to stop charging; K1, K2, K3 and
K4 will be disconnected; then, the electronic lock will be unlocked.
Note. If the non-on-board charger stops charging because of serious fault, operator is required
to conduct complete charging starting setting, in order to restart the charging.
