Charging APIs for Building Management Systems
A building that already has systems does not want a second control room for charging. We build the interface between the charging platform and what the building already runs, so charging appears where the facilities team already looks and stays inside the limits the building already has.
What buildings usually ask for, how we design and build the interface around that, and what the integration work looks like with our team alongside yours.
Talk to Our Integration TeamFor A building owner, facilities technology team or BMS integrator putting charging into a building that already has systems running.
What buildings usually ask for
- 1
Charging inside the building's own dashboard
So facilities staff see the chargers next to everything else they are responsible for, rather than logging into a separate system they will forget exists.
- 2
One honest number for what charging is drawing
Live, and trustworthy enough to plan against. This is the request that comes up on every project.
- 3
The ability to tell charging to back off
When the building is close to its limit, charging reduces rather than the building tripping. A limit the building sets and charging respects.
- 4
Charging inside the access arrangements that already exist
A building that already knows who everyone is should not need a separate list of who may charge.
- 5
Reporting that lines up with the building's own
Energy attributed to tenants, floors or cost centres the way everything else in the building already is.
What no facilities team actually wants is the building system running charging. The interface is the product, not a takeover.
How we build it
- 1
We start from what the building runs
Which system, what it already does, and where charging has to appear in it. The interface is designed to that, not to a generic idea of a building.
- 2
We build to suit the system on site
What the interface speaks and what it carries is decided by the building, and the design keeps the fast, small things separate from the heavy reporting so neither gets in the other's way.
- 3
We integrate it with your team
Our software delivery centre works alongside the facilities team or the BMS integrator through the connection and the commissioning.
- 4
We decide the failure behaviour deliberately
What charging does when the building system is unreachable is a decision made in advance and tested, rather than found out during a busy afternoon.

Frequently asked questions
Do we need the building system to control charging?
No, and it is usually the wrong arrangement. What buildings need is visibility, one honest number for what charging draws, and the ability to tell charging to back off. Charging keeps deciding how to distribute that among the bays.
Which building systems can you connect to?
Tell us what is running on site. The interface is built to suit what is there rather than requiring the building to adopt something new.
What happens if the building system is unreachable?
That behaviour is decided in advance and tested. The failure everyone wants to avoid is charging that either stops entirely or ignores the building limit, and neither should be the default by accident.
Who does the integration work?
Our software delivery centre, working alongside your facilities team or your BMS integrator.
How do we start?
Tell us what the building runs and what the supply limit is. That is usually enough to scope the interface.
Charging going into a building that already has systems?
Tell us what the building runs and what the supply can take. We will come back with what the interface looks like and what the integration involves.
