# Flats, VvE and offices

Many chargers on one shared connection: fair sharing per second, per-user metering and billing, card authorisation, and the building's own management system (BMS/GBS) monitoring or controlling the chargers.

## The problem

A VvE garage or an office car park has one connection and a growing number of residents or employees with a car. Upgrading the connection is slow and expensive. Load balancing on the existing connection is not.

## What we do

- One site controller on the P1 port drives up to 10 chargers per bus; larger garages use several buses or GridShield.
- Every charger meters its own sessions; the platform assigns them to users and produces the overviews the VvE administrator or the employer needs for billing.
- NFC cards or the app decide who may charge; guests can be given a code.
- The building's **building management system (BMS or GBS, or its energy module, BEMS)** can monitor and control the chargers over Modbus, the REST API or Matter, so charging becomes one more system the building manages.

## Parts

Chargers of any tier; EVSE-SC-02 or GridShield; NFC readers; the platform with per-user reporting. A Dutch page for VvE administrators is planned.
