Large-Scale Destination Charging Without Grid Upgrades
Enablelarge-scale AC and DC charging points across workplaces, offices,
hotels, airports and parking facilities — while intelligently sharing the available
power in real time.
The challenge
Destination charging sounds simple. Operating it at scale isn't.
AC charging at scale means hundreds of concurrent sessions
Car parks, offices, and retail locations were never designed for 20, 50, or 100 simultaneous EV
chargers. Without smart management, the building connection gets overwhelmed and the
charging experience breaks down.
Existing Grid Capacity Isn't Used Efficiently
Many destination charging sites already have enough available power—they just can't distribute it
intelligently. Fixed load allocation strands capacity on idle or low-demand chargers, reducing
charger utilization and slowing down charging sessions when power could be used elsewhere.
Multi-site operations run blind
Retail parks, offices, hotels — each with different building loads, grid contracts, and usage
patterns. Without a unified data layer, energy costs and fault response are guesswork.
Grid congestion across Europe is structural
New connections are delayed by years. Deploying more charge points without hitting grid
ceilings isn't a nice-to-have — it's the only path to growth.
Let’s change that
The Solution
the control layer
for high-power charging
A unified platform that coordinates chargers, grid capacity, and energy assets in real time.
Dynamic Load Allocation
Serve more drivers. Stay under your grid limit.
Distributes available power dynamically across all active charging sessions
Reallocates unused capacity instantly when a vehicle reaches full charge or disconnects
Prevents any single spike from breaching the site's contracted grid limit
Works across mixed hardware from any charger brand
Building Load Integration
Charging that fits around the building, not the other way around
Monitors total site energy consumption — not just EV load — in real time
Automatically adjusts charging power when building demand rises (HVAC, elevators,peak shifts)
Protects the grid connection shared between building systems and charginginfrastructure
No separate metering required — integrates with existing building energy setup
Multi-site Management via HARMON-E
One platform. Every site. Full visibility
Centralised dashboard across all charging locations — real-time load, session data,energy costs
Site-level configuration: set individual load limits, priority rules, and charging schedulesper location
