Load balancing without upgrading the supply

The biggest obstacle to electrifying a car park is almost never the charger itself — it's the available power. You see it at hotels, campsites, fleet depots and residential buildings alike: upgrading the electrical supply can cost thousands and take months of back-and-forth with the grid operator. There's an alternative: intelligently sharing the power that's already there.

The same problem across very different businesses

A hotel with twenty garage spaces, a campsite with pitches spread across the grounds, a fleet depot with several vans charging overnight, or a residential building with a single electrical panel: they all share the same constraint. The contracted capacity is sized for the building's normal loads, and if several vehicles try to charge simultaneously at several kW each, that capacity runs out immediately.

The traditional fix is to upgrade the contracted power — expensive, slow, and sometimes not even possible depending on the local substation's capacity.

Dynamic load management: making the most of what you have

Instead of upgrading the supply, you can monitor the building's total consumption in real time and distribute among the connected chargers only the power that's actually free at any given moment. When there's headroom, cars charge faster; when the rest of the building is consuming heavily, the system automatically reduces charging power to stay within the contracted limit — with no manual intervention needed.

This is exactly what AskaCharge's Smart Charging / SPL (Line Protection System) feature does: you set a power limit per location and the system dynamically distributes it across the active connectors at that location via OCPP, without touching the building's wiring.

Regulatory backing

Dynamic load management is supported by REBT ITC-BT-52, the Spanish technical standard governing EV charging installations. For residential buildings specifically, the Horizontal Property Act establishes that the installation of a charging point in a private parking space cannot be blocked — dynamic load management is what makes it practical to install several of them without hitting the building's electrical limit.

Who benefits

Any business with multiple parking spaces and limited electrical capacity: hotels, restaurants with their own car park, campsites, company fleets, residential communities... Load balancing turns "we need to upgrade the supply" into "we can start charging today" — whatever the type of business.
