Inputs

Number Input Description range default
1 CCS_Switch locking or unlocking CCS latch. A pulse is needed. While charging is not activated unlock is not possible. pulse
2 Start_Charging If charging is enabled the process can be started manually. 0 or 1 0
3 I_request requested chrging current 0 - 300 A
4 Bat_Condition Enable Batter Conditioning 0 or 1 0
5 Bat_Reset Resting of BMS in case of a failure 0 or 1 0
6 Stop_Charging Stop charging 0 or 1 0
7 T amb ambient temperature can be used for battery thermal model -20 - 60 °C 20

Outputs

Number Output Description range default
1 PP_connected Feedback if cable is connected via PP contact 0 or 1
2 PP_Imax maximum current allowed by cable 0 - 300 A
3 PP_state current state of PP is important for higher level communication. ERROR: -1, DISCONNECTED: 0, CONNECTED: 1, DEPRESSED: 2
4 CP_status Current status of the EV in lower level communication: ERROR: -1, idle (A): 0, Connected (B): 1, charging (C): 2
5 CP_Imax maximum current send from EVSE by CP signal (duty cycle)
6 CCS_locked status if CCS inlet is locked (1) or unlocked (0)
7 CC_Imax maximum current derived by EVCC
8 ch_enabled charging is enabled
9 Iset_a refernce current for phase A
10 Iset_b refernce current for phase B
11 Iset_c refernce current for phase C

29 Imax_OBC maximum current of onboard charger

Component dialogue box and parameters

The EVCC UI subsystem is organized in one tab for defining the interface

Tab 1 - General

Parameter Code Name Description
execution rate Ts The slower execution rate (in relation to the EVCC) defines the timing for the scada inputs for the EVCC. [s]
