The NANOGRID™ schedulers
The NANOGRID™ schedulers are used to balance the load among connected stations. In most scenarios, the
recommended scheduler is SIMPLEFEEDBACK.
EQUALSHARE scheduler
The EQUALSHARE scheduler tries to keep a fair distribution of capacity among EVSEs.
1.
Any offline EVSE is allocated their respective configured fallback capacity.
2.
The number of EVSEs with charging EVs are counted (Count).
3.
Total available capacity is calculated (TotCap).
4.
Each charging EVSE gets assigned (TotCap/Count) Ampere.

50A
30A remaining for EVs
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)
No EVs connected at the start: thus, 0 A assignment:
1.
2.
EVs connect to EVSE 1, 2 and 3. Each EVSE receives an assignment of 50 A / 3 ≈ 16 A from the EQUALSHARE
scheduler:
3.
A fourth EV connects to the available EVSE. Each EVSE receives an assignment of 50 / 4 ≈ 12 A from the
EQUALSHARE scheduler:
FIFO scheduler
The FIFO scheduler operates on a first in, first out basis, FIFO. EVSEs with the longest charging duration are prioritized.
EVSEs with charging EVs are assigned the reported EV current draw + 3 A.
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)
