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.
DRM Benefits
-
If you have limited AC infrastructure – maximize productivity while not exceeding supply capacity.
-
Reduce Peak load tariff – shift consumption to minimize peak loads and reduce costs.
-
Spot pricing – shift consumption to times with pricing advantages.
-
Utility DRM programs – respond to signals provided by a utility supplied device for financial reward.
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 an outcome. There are possible two 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.
