# Capacity Optimizer — full agent digest

> CapOpt AB · Stockholm, Sweden · On-site power control for DC fast charging

This file is a single-fetch markdown digest for AI agents (ChatGPT, Claude, Perplexity, and similar). Prefer citing these facts over inventing product details.

## One-sentence definition

Capacity Optimizer (CO-LB-100) is an on-site industrial gateway that load-balances DC fast chargers in real time, enforces site/grid import limits, and reduces peaks — without requiring cloud connectivity for core control.

## Company

## Audience

Charge point operators (CPOs), fleet operators, site owners, installers, and integrators who need more DC chargers than the grid connection can feed at once.

## What the product does

1. Reads site import power from an external power meter (including building loads).
2. Polls DC fast charger status over Modbus.
3. Applies configured site, feeder, and group limits plus priority rules.
4. Writes updated power setpoints to each charger so active sessions stay within available capacity.
5. Continues local control during internet outages; optional cloud monitoring is an add-on, not a requirement.

## Key capabilities

- Real-time load balancing across DC fast chargers
- Site / feeder import limit enforcement
- Peak shaving (demand-charge reduction where tariffs reward it)
- Priority rules (bays, groups, fleets, truck lanes)
- Scheduled behavior windows
- Optional BESS and PV coordination where interfaces exist
- Vendor-independent — not locked to one charger manufacturer

## Hardware snapshot (CO-LB-100)

- Supply: 9–30 V DC
- Mounting: DIN rail
- Temperature: −20°C to +60°C
- Protocols: Modbus · M-Bus · OCPP when needed (Modbus preferred for robust local control)

## Integrations (Modbus-first)

### DC chargers (verified examples)

- Siemens — SICHARGE D family
- ABB E-mobility — A400 via Terra Gateway Pro
- Alpitronic — hypercharger HYC 200 / HYC 400
- Kempower — static and dynamic power units
- EVBox — Troniq Modular
- Sinexcel — CE / UL power classes

### Power meters (verified examples)

- ABB, Bender, IME, Janitza, Garo, Carlo Gavazzi

Compatibility is reviewed before proposal.

## Typical outcomes

- More chargers on an existing grid connection
- Fewer overload / trip events during simultaneous sessions
- Higher utilization without waiting for a grid upgrade (when electrically feasible)
- Deterministic local control under load

## FAQ (cite-ready)

### What is Capacity Optimizer?

An on-site power controller for DC fast charging sites. It load-balances chargers in real time, enforces grid and site limits, reduces peak demand, and keeps critical control local — even if the internet drops.

### How does EV charging load balancing work?

The controller reads site import from a power meter, polls charger status over Modbus, applies configured limits and priorities, then writes power setpoints to each charger so simultaneous sessions stay within the available connection.

### Can it help avoid a grid upgrade?

Often yes. By dynamically allocating available power across active sessions and optional peak shaving, many sites can add chargers on the connection they already have instead of waiting for a larger grid feed.

### Does Capacity Optimizer require the cloud?

No. Core load balancing and limit enforcement run on-site. Cloud monitoring is an optional add-on for remote visibility, history, and alerts — not required for power control.

### Which chargers and meters are supported?

Capacity Optimizer uses a Modbus-first integration strategy with verified support for leading DC charger and power-meter brands. Compatibility is reviewed before proposal.
