Table 5 - 5 Phases of the DC charging sequence in a Combined Charging System (CCS)
Phase Status
1
Status change and actions
1. Vehicle not connect -
ed
A1 CP = 12 V DC
A1 If required, the charging station performs insulation monitoring on a cyclical basis
2. Connect vehicle

B1 Vehicle charging connector inserted in vehicle, CP switches to 9 V DC
3. Initiation

B2 PWM is switched on with a pulse duty factor of 5%
Digital communication established between vehicle and charging station
B2 Exchange of charging parameters between vehicle and charging station
B2 Verification of output voltage between DC+ and DC- <60 V
B2 Vehicle sends maximum limit values for charging current and voltage to the
charging station
B2 Vehicle locks vehicle charging connector in vehicle charging inlet
B2 Charging station reports maximum charging current and charging voltage values
back to the vehicle

C2/D2
Vehicle switches to status C2 or D2 by closing switch S2
4. Cable test
C2 Vehicle confirms that the vehicle charging connector is locked
C2 Vehicle requests cable test
C2 Charging station tests cable and reports insulation to vehicle
C2 Cable/insulation test complete
C2 Vehicle and charging station ready to charge
5. Pre-charging
C2 Vehicle sends pre-charging request with <2 A and the voltage required to start the
pre-charging process to the charging station
C2 Charging station adjusts the voltage to the value required by the vehicle and limits
the charging current to 2 A, maximum
C2 Required voltage reached
C2 Vehicle closes its DC contactors if voltage difference <20 V
C2 Vehicle issues charging enabled (vehicle switches to “Ready to charge” state)
C2 Pre-charging circuit blocked and DC power supply connected
C2 Charging station sends ready-to-charge signal to vehicle
6. Charging
C2 Vehicle sends the continuously required voltage to the charging station
C2 Charging station continuously adjusts the voltage to the value required by the vehi -
cle
C2 Charging station continuously reports actual charging current and actual charging
voltage, as well as actual maximum limit values to the vehicle
C2 Charging station adjusts the charging current in accordance with the vehicle spec -
