Dynamic Load Management for EV Charging
Dynamic load management keeps project capex and running costs down by avoiding grid connection upgrades and higher network tariffs. The controller measures the site in real time and gives the chargers whatever capacity the building is not using.
A local controller, wired to the meter and the chargers
We use Coneva's SmartBox as the on-site controller. It creates a hard-wired local network to each charger, reads the site energy meter, and allocates power based on building load, charger use and the priority rules you set.
Reads the meter in near real time
Charger limits update about every three seconds based on the measured site load.
Protects your site limit
The building is served first. Chargers share only the capacity that is left over.
Works with solar and tariffs
Shift charging to match rooftop generation or the cheapest tariff window.
Priority rules
Give fleet vehicles, specific bays or residents priority when capacity is tight.
Keeps working offline
Control runs locally on site, so limits hold even if the internet connection drops.
One dashboard for every charger
Status, energy use and faults for each charge point, with remote resets and limit changes.
Pick the rules that suit the site
Dynamic
Monitors power at the grid connection and on-site solar, then distributes what is available. When the building is quiet, chargers get more.
Schedule-based
Charges in the lowest-cost tariff windows, or follows a solar timetable when cutting emissions is the priority.
Fair share for apartments
Keeps shared capex to a minimum while each resident pays for installing and running their own charger.
Engineering, hardware and set-up
Load management only works if the site is measured properly and the settings match the switchboard. We do both before a charger goes on the wall.

Load management, energy management and smart charging
These terms get used interchangeably. On a real site they are layers of the same job.
- Load management shares the available supply between chargers so the site never goes over its limit. Static load management sets a fixed cap. Dynamic load management measures the building’s actual load at the main switchboard and gives the chargers whatever capacity is spare at that moment.
- Energy management looks at the whole site: chargers, building loads, solar and batteries. It decides when charging happens as well as how much power each charger gets, for example moving charging to off-peak rates or to the middle of the day when solar is exporting.
- Smart charging is the charger-level capability that makes both possible: chargers that can be controlled remotely, usually over OCPP or Modbus, with their charging current adjusted in real time.
What it saves
Without control, a handful of chargers on a typical apartment or commercial supply can push maximum demand past the connection limit or trip circuits at the evening peak. Managing the load lets you install more chargers on the supply you already have, avoids or delays network augmentation, and keeps demand charges in check.
Solar and off-peak charging
Where a site has solar, energy management can look after building loads first and send surplus generation to the chargers. On time-of-use tariffs, charging can be scheduled for the cheapest periods, with priority rules so vehicles that need to leave early still get the charge they need.
