Dynamic Load Management (DLM) helps prevent the site’s electricity supply from being overloaded by adjusting EV charger power as demand changes.
How does dynamic load management work?
A DLM system monitors a site’s electricity demand and adjusts the power available to connected EV chargers.
For example:
- A building’s electricity demand increases.
- The system detects that less capacity is available for EV charging.
- Charging power is reduced across selected chargers.
- When building demand falls, more capacity can become available for charging.
This helps sites make better use of their existing electrical capacity without necessarily needing to increase their grid connection.
Why is DLM important for EV charging?
Dynamic load management can help businesses:
- Reduce the risk of exceeding their agreed electricity supply limit.
- Support more EV chargers within available site capacity.
- Balance building demand with vehicle charging.
- Make better use of available electrical infrastructure.
It is particularly useful for workplaces, commercial buildings, depots and sites with multiple chargers.
How does Electric Miles support dynamic load management?
Electric Miles has an integration with Charge-M8’s Libra dynamic load balancing device.
Libra measures building electricity demand in real time and shares this information with Electric Miles’ emPACT CPMS over OCPP. emPACT can then adjust connected charger output to help keep total site demand within the agreed supply limit.
This connects live building demand with charger management, rather than treating EV charging as a separate electricity load.
For eligible sites, live capacity information can also support flexibility activity through Electric Miles’ SmartFlex platform.

Frequently asked questions
Is dynamic load management the same as smart charging?
Not exactly. DLM focuses on balancing electricity demand against available site capacity. Smart charging can also consider factors such as tariffs, schedules and grid signals.
Does DLM mean vehicles charge more slowly?
Charging power may be reduced when site demand is high. When more capacity becomes available, charging power can increase again.
Can DLM help businesses install more EV chargers?
It can help businesses make better use of existing electrical capacity, although the number of chargers a site can support depends on its supply, demand and charging requirements.
