Dynamic load balancing monitors a site's total electricity demand in real time and automatically adjusts how much power each EV charger delivers, so the site never draws more than its grid connection allows, without needing that connection upgraded.
Reading the Whole Site, Not Just the Chargers
A depot or car park doesn't only run chargers. Lighting, HVAC, workshop equipment, and other loads all draw from the same incoming supply. Dynamic load balancing measures that entire picture continuously, usually via a CT meter clipped onto the incoming feed, and works out how much headroom is left for charging at any given moment.
As other loads rise and fall through the day, charging output adjusts automatically to stay within the site's total capacity, speeding up when there's headroom and easing back when there isn't.
Static vs. Dynamic Load Balancing
| Static | Dynamic | |
|---|---|---|
| How it allocates power | Fixed share per charger, set once | Recalculated continuously in real time |
| Accounts for other site loads | No | Yes |
| Risk of nuisance trips | Higher if usage patterns change | Low, adjusts before limits are hit |
Where It Sits in the System
Dynamic load balancing is the software logic; group charging is the hardware architecture it usually runs on top of, with a master unit and shared satellite terminals. Together they let a depot fit more charging bays onto an existing grid connection than a fixed, one-charger-per-bay layout ever could.
Neutron's Approach
Our Master Units and modular charging systems run dynamic load balancing as standard, continuously reallocating power across every connected bay so sites can scale up charging capacity without a parallel grid connection upgrade.
What's the difference between static and dynamic load balancing?
Static load balancing splits available power into fixed shares per charger, set once at installation. Dynamic load balancing measures actual site demand continuously, including non-charging loads, and reallocates power in real time as conditions change.
Does dynamic load balancing require a CT meter?
Yes, in most installations. A current transformer (CT) meter clips onto the site's incoming supply and measures total site load in real time, giving the load balancing system the data it needs to work out how much headroom is left for charging.
Worried your site can't support more chargers?
Dynamic load balancing often fits more bays on the grid connection you already have.
