Apartment buildings
Charging infrastructure for apartment buildings
From 6 to 1,000 charge points — vendor-independent, dynamically controlled and billed in a metrology-compliant way. Whether wallboxes in an underground garage or charging stations on a housing complex's outdoor spaces: aCharge distributes the available power fairly across every space.
What you get
Plan, install, monitor, bill
The four steps between “we would like charge points” and a running installation — from one source, with one point of contact.
Concept
Technical feasibility, on-site survey, documentation and, where needed, a load profile measurement.
Planning
Detailed and, on request, tender planning, matched to connection capacity and expansion stages.
Installation
Built by POSID or your own contractor — the controller is vendor-independent.
Operation
Monitoring, user management and metrology-compliant billing then run on automatically.
Capabilities
What the system takes off your hands
Vendor-independent
Wallboxes and charging stations from many vendors over OCPP and Modbus TCP — mixed if need be.
Scalable
Start with a few charge points and grow. Up to 1,000 per site.
Reliable
The local controller keeps regulating even if the internet connection drops.
Always current
Automatic software updates protect your investment over its lifetime.
Load management
Dynamic and multi-stage, integrable even into complicated existing installations.
User management
Manage users and charge cards; users can register themselves.
Billing
Automatic metrology-compliant billing, optionally with SEPA collection.
Monitoring
Remote monitoring of the charging infrastructure with alerting on faults.
Underground garage
Charging stations and wallboxes in the underground garage
In most housing complexes the charging infrastructure sits under the building, where the constraints differ from a company car park: one connection for everyone, parking spaces with different owners, and no mobile reception. Four points decide whether the installation still holds up in ten years.
One house connection, many spaces
The garage hangs off the same connection as the flats, lifts and heating. Split statically, the capacity usually covers a handful of charge points; regulated dynamically, the controller distributes exactly what is spare at that moment — and at night, when most cars charge, that is a great deal.
No reception below ground
Mobile reception ends at the ramp. Control therefore runs locally on the controller in the plant room and does not need the cloud to allocate power — the uplink serves administration and billing, not regulation.
Base installation now, wallbox later
Sizing the riser, distribution and metering position once for the final build-out costs considerably less than opening up the garage three times. Individual owners can have their wallbox fitted later at their own expense without the association having to decide again.
Every space bills for itself
Sessions are attributed to their access medium in a metrology-compliant way and billed automatically, even when owners, tenants and visitors share one installation. The property manager does not receive a lump item to split across parties by hand.
Recommendation
For this kind of site: aCharge DYLAMO
These sites typically have mixed-vendor wallboxes across several measuring points, often alongside a PV array and a heat pump — exactly what DYLAMO is built for.
