Product: Capacity Optimizer (CapOpt AB)

Capacity Optimizer is for sites that need more chargers than the grid can feed at once.

## Public DC fast charging hubs

- **Challenge:** Simultaneous sessions exceed the grid connection at peak hours.
- **Approach:** Distribute available site power across active sessions in real time.
- **Outcome:** Higher utilization — more vehicles charged per day without a grid upgrade when feasible.

## Fleet depots

- **Challenge:** Shift-change charging spikes overload the connection; fixed schedules ignore real-time availability.
- **Approach:** Dynamic allocation and priorities aligned to operational windows.
- **Outcome:** Depots charge more vehicles within existing electrical limits.

## Truck / high-power charging

- **Challenge:** High-power truck chargers can exceed the connection in minutes.
- **Approach:** Enforce import limits and priorities across lanes/bays in real time.
- **Outcome:** Truck charging stays within the site envelope without nuisance trips.

## Sites with BESS and solar

- **Challenge:** Storage and PV change available power; chargers must track that envelope.
- **Approach:** Optional coordination with BESS/PV where interfaces exist, plus meter-based site limits.
- **Outcome:** Chargers use on-site generation/storage within configured electrical limits.
