1.
No EVs connected at the start: thus, 0 A assignment:
2.
EVs connected to EVSE 1, 2 and 3:
•
EV1 draws 16 A
•
EV2 draws 16 A
•
EV3 draws 13 A
All EVSEs gets allocated their maximum assignment from the FIFO scheduler: 16 A.
3.
A fourth EV connects to the available EVSE. As there is no available capacity to charge another EV (minimum
required is 6 A), the EVSE gets no current assignment:
4.
EV1 disconnects, EV4 receives an assignment of 16 A from the FIFO scheduler:
SIMPLEFEEDBACK scheduler
The SIMPLEFEEDBACK scheduler uses the EVSE energy meter feedback to assign the capacity. Each EVSE periodically
reports the EV current draw to the controller.
Assignment is done individually per phase. If an EVSE uses a single-phase for charging (either physically connected, or
the connected EV only draws on one phase), that will be considered.
CTEK E-Mobility AB
Any offline EVSE is allocated their respective configured fallback capacity.

2.
EVSEs with charging EVs are assigned the reported EV current draw + 3 A. EVSEs with the longest charging
duration are being prioritized if the total capacity limit has been reached.
3.
Remaining EVSEs with charging EVs but invalid feedback (e.g. broken energy meter) share the remaining capacity
equally. Similar to EQUALSHARE.
Example:
Setup: Distribution Board MAINPANEL 50 A with 4 EVSEs.
STATION_1: EVSE1 (16 A)
STATION_1: EVSE2 (16 A)
STATION_2: EVSE3 (16 A)
STATION_2: EVSE4 (16 A)
1.
No EVs connected at the start: thus, 0 A assignment:
2.
EVs connected to EVSE 1, 2:
•
EV1 draws 14 A
•
EV2 draws 6 A
EVSE1 receives an assignment of 16 A as 14 + 3 = 17, but EVSE maximum allowed is 16 A. EVSE2 receives an assignment
of 9 A as 6 + 3 = 9.
3.
EV3 connects to EVSE3, EV4 connects to EVSE4:
•
EV3 draws 16 A
•
EVSE4 reports that energy meter values are invalid!
EVSE3 receives an assignment of 16 A from the SIMPLEFEEDBACK scheduler. EVSE4 receives an assignment of the
remaining capacity of the grid: 50 –16 – 9 – 16 = 9 A
