Fleet charging dock

Service robots — charging dock, fleet interface. Part of the glass family — like our glass BESS, biogas plant and CHP.

What is Fleet charging dock?

Every service robot returns to a dock to charge. Individually that is a small load; a fleet docking together after closing time creates a new night-time peak.

That load shifts well: the robots are not needed again until morning. What is missing is the measurement — without a meter at the dock the fleet stays invisible in the load picture.

What is measured here

  • Charging power at the dock (fleet total)
  • Charging window: when docked, when back in service
  • Simultaneity with the building loads
  • Number of charging cycles per day

How we connect it — read-only

  • Modbus meter on the dock feeder — the real fleet load.
  • Clamp-on current transformers as a retrofit where no dedicated feeder exists.
  • Vendor fleet API for docking and deployment times where available.

What the AI does

  • Staggers overnight charging instead of letting the fleet start together.
  • Places charging in low-price and PV hours within the deployment window.
  • Makes the fleet visible in the overall load picture instead of leaving it as background.
  • Detects diverging charge durations as a sign of battery ageing.

Is a robot fleet’s charging load relevant at all?

Per robot it is small. It becomes relevant through simultaneity: if the whole fleet docks together after closing, an additional peak forms in an hour when little else runs.

Basis: plant engineering

Why is the vendor portal not enough?

It shows the robots’ state of charge, not the electrical load at the service connection. For the load picture what counts is the meter at the feeder — vendor-neutral and inside your own building.

Basis: plant engineering

Can charging be shifted without disrupting service?

Usually yes, because many hours lie between docking in the evening and deployment in the morning. The window is far longer than the charging time.
