EV Charging for Apartment BuildingsScalable solution without vendor lock-in
Is your apartment building (MDU) planning to install EV charging? Whether it's for an individual resident's charging point or a shared project for the entire building – proper planning saves thousands in costs and prevents costly mistakes.
Wattery offers a charging solution for apartment buildings that scales from one outlet to dozens of charging points – without expensive retrofits or lock-in to a single vendor.
Apartment buildings and EV charging – why does starting right matter?
The most common mistake in apartment buildings is allowing individual, cheap, so-called "dumb" chargers without a shared plan. This almost invariably leads to problems:
A well-planned charging system for apartment buildings prevents these pitfalls and ensures the solution works even as the number of chargers grows.
A good charging solution for apartment buildings is always
Scalable
Ability to expand from one charging point to dozens without upgrading the electrical connection or re-laying cables.
Fair
Only residents who charge pay. No financial burden for residents without an EV. A transparent and hassle-free model for the board and property manager.
Open (OCPP)
Based on the OCPP standard, meaning the building is not dependent on a single hardware vendor or operator.

The building's grid capacity is limited. Dynamic load balancing is the brain of the system: it protects the building, keeps demand charges in check and enables future expansion.
What are the benefits?
-
Real-time monitoring
When electricity is consumed elsewhere (e.g. lifts, ventilation, or communal lighting) charging power is automatically reduced.
-
Night optimisation
When overall consumption is low, cars charge at full power.
-
Grid capacity fees under control
Wattery calculates the building's demand index to ensure the system is optimally sized – neither over- nor under-dimensioned.
Automatic individual billing – hassle-free for the property manager
Wattery makes billing automatic. The board or property manager doesn't need to track meter readings or handle manual invoicing.
Usage-based billing (kWh)
Each resident pays only for their own consumption.
Spot price optimisation
Charging can be scheduled during cheap hours on the electricity market.
Fully automated flow
The entire flow from metering to payout is automated – the board handles zero administration.
Open OCPP standard – protecting your building's investment
In a fast-changing market, locked systems represent a financial risk; with OCPP you ensure that the hardware doesn't become worthless if a provider disappears.
To work optimally, chargers must support load balancing via OCPP, known as "Smart Charging". Choose a charger that supports this. Compatible chargers
What does OCPP mean in practice?
-
Freedom: the operator can be switched without replacing equipment
-
Long lifespan: equipment remains useful even as the market evolves
-
Value retention: the investment is not dependent on a single provider
-
Load balancing: with OCPP, load balancing can be implemented across chargers from different manufacturers
How a charging project in an apartment building works
Assessment
Current capacity and the residents' actual needs.
General Meeting Decision
Clear decision materials for the board ahead of the General Meeting (AGM).
Installation and commissioning
Installation and configuration of the system.
Operations and support
Remote monitoring and automatic handling of faults.
Take the next step – without costly mistakes
Avoid short-term solutions – invest in a complete charging system sized for tomorrow's needs.
