Demand Response Management
Demand Response Management (DRM) is a licensed feature that can be added to EcoCharge® ECO973 Three Phase and ECO971 Single Phase Chargers.
It allows the chargers to coordinate with each other over a network to limit the power they use. A DRM group is created by configuring one charger as the group controller. Either grouped by Wi-Fi or Ethernet​​​​​​.
For each group, an event Trigger is set that causes the DRM system to respond:
-
Fixed: a fixed energy consumption limit is set for the group.
-
Time variable: as for a fixed limit, but this limit can vary by time of and day of week.
-
External input: as for a fixed limit, but these limits are only acted upon when the limit’s corresponding IO expansion board input is active.
Each response results in two possible outcomes:
​
-
Battery Change: An optimized method to get batteries ready to return to service.
​
-
Opportunity: An optimized method to return charge to batteries at high risk of reaching full depth of discharge during service.
