Site-power control

Help prevent charger demand from overloading the building.

The controller watches how much power the site is already using and shares the remaining capacity across compatible chargers. Your quotation lists the meters, limits, priorities and fallback behaviour for your site.

Where it fits

Use power control when chargers share capacity with a live site.

Use reliable electrical data and a safe operating ceiling whenever chargers share power with an active property.

1

Hotel, mall and office buildings

Adjust charging allocation as lifts, kitchens, cooling, lighting and other building loads change through the day.

2

Fleet departure groups

Use an agreed priority rule to direct available depot power toward the vehicles with the earlier or more urgent operating window.

3

Shared residential parking

Phase charging groups around the building supply, resident demand and the chosen access and electricity-allocation process.

4

Solar, storage and charging sites

Coordinate the charging target with available generation, storage operating limits, other site loads and the confirmed operating mode.

CONTROL OPTIONS

Choose what shares power before choosing the controller.

Start with the buyer problem. Your quotation then lists the meters, communications, compatible chargers and response rules.

01

Whole-site headroom control

Power decision
Charger power rises or falls with the spare capacity available in the building
What shares power
Building loads and charging groups managed under one site limit
Charger interface
Charger communication and command path confirmed for the selected equipment
Best starting fit
Hotels, malls, offices and apartments sharing a live building supply

Your quote lists the meter points, update speed, reserve margin and fallback behaviour.

02

Charging-group power sharing

Power decision
A fixed charging allowance is distributed across the connected ports
What shares power
One charger group or feeder managed inside a defined allocation
Charger interface
Compatible charger models, gateway and network method confirmed in the quote
Best starting fit
Sites with a known charging budget and changing simultaneous use

Your quote lists the group limit, sharing rule, minimum service and behaviour when communications stop.

03

Departure-priority fleet control

Power decision
Available depot charging power follows the agreed vehicle priority schedule
What shares power
Vehicle or charger groups linked to route and departure needs
Charger interface
Fleet charger and management-system interfaces confirmed per project
Best starting fit
Return-to-base fleets with different departure times or route energy needs

Your quote lists priority inputs, operator overrides, exception handling and reports.

SAMPLE OPERATING VIEW

See how building power and charging can appear in one view.

The sample screen brings grid, building, solar, storage and charging signals together with demonstration data.

Sample site-energy interface

Demonstration data shows one possible operating view. Your quotation lists the measurements, limits, controls, alarms and integrations included.

This example dashboard shows the readings, alarms and controls that can be included for your site.

Complete the controlled stack

The controller connects the site limit to the charging plan.

Apply one site-power limit across the AC lane, DC lane and operating platform.

Before ordering

Send recent electrical data so we can set a safe charging limit.

Define what is measured, which chargers can be controlled and how the site should behave when data or communications change.

  • Single-line diagram, supply voltage, transformer, switchboard, feeder and protection information
  • Recent site-demand data and the owner- or utility-confirmed operating ceiling
  • Measurement points, meter or sensor interfaces, sampling needs and reserve margin
  • Charger families, quantities, ratings, communications and intended control groups
  • Priority, minimum service, operator override, alarm and fallback behaviour
  • Commissioning checks, required documents, warranty and support responsibilities

Buyer questions

Answers before you select a dynamic load-management system.

What does dynamic load management do in plain language?

It measures how much power the site is using, calculates what remains for charging and shares that power across compatible charger groups using the priorities listed in your quote.

Does load management remove every need for an electrical upgrade?

Not always. Power control can use existing capacity more efficiently, but your electrical data still determines whether feeders, switchgear, transformer capacity or other works are needed.

Can AC and DC chargers share one site-power limit?

Yes, when the selected meters, chargers and command interfaces support the design. Your quotation lists which charger groups are controlled and how priority works.

What happens if communication is interrupted?

Your quotation lists the safe charger behaviour, local limits, alarms, operator actions and restart checks to use if communications stop.

What data should I send for a site-power plan?

Send the single-line diagram, transformer and switchboard data, recent demand profile, intended chargers, network information, operating priorities and the owner- or utility-confirmed site limit.

Use this system

Add site-power control to your charging blueprint.

Choose the site, spaces, market and connectors. Your brief will include the recommended charger groups and local electrical inputs needed to set the site-power limit.

The first plan shows which data is needed. Your quotation lists the exact controller and operating behaviour.
