Dynamic load management
for housing company.

Same grid connection, more charging. KotiCharge's cloud-based load management tracks the building's electricity use in real time and shares the free power among the chargers — whatever the brand. The main fuses don't trip, and the housing company isn't locked into one manufacturer's equipment.

Without load management — fuses trip

Ten 22 kW chargers can draw up to 220 kW. At the evening peak, the main fuses overload.

Static load management — capacity goes unused

Chargers get a fixed power reserve sized for the worst peak. At night, when the connection has plenty of room, cars still charge slowly.

Dynamic load management — full capacity in use

Charging gets exactly the power that is free at any moment. In the evening, power is shared fairly; at night, cars charge at full power.

Background

What is dynamic load management?

A housing company's electricity use varies throughout the day. Dynamic load management makes use of that variation: chargers use the power the rest of the building doesn't need at that moment.

Static load management

A fixed total power is reserved for the chargers at the switchboard and shared among the cars charging. The system doesn't know what the rest of the building is using, so the reserve must be sized for the worst consumption peak of the year — and most of the time, part of the capacity goes unused.

Dynamic load management

The building's total consumption is measured in real time at the main switchboard. Total charging power is raised when other consumption is low and cut as soon as it rises. The main-fuse limit is never exceeded, and the connection's full capacity is available for charging.

Example — daily load profile

Housing company of about 30 apartments, main fuses 3 × 100 A (approx. 69 kW)

Other building consumption Free for charging (dynamic)

Static limit, all day

12 kW

Dynamic at night, up to

~50 kW

Illustrative example. Safety margin 5 kW. Actual values depend on the building's grid connection and consumption.

22 kW chargers

22 kW chargers + dynamic load management

Most chargers support 22 kW, and charging speed is usually limited by the car. Ten cars charging at once would still need 110–220 kW — more than the entire grid connection of most housing companies.

Full charging power whenever the connection has room
Power is shared evenly when several cars charge at once
Single-phase cars are balanced per phase
When one car is full, its power moves to the others immediately

Example — 10 × 22 kW chargers, overnight 10 pm–7 am

Static 12 kW limit 1.2 kW / car

Overnight per car: ~11 kWh ≈ ~60 km of driving

Dynamic load management ~5 kW / car

Overnight per car: ~45 kWh ≈ ~250 km of driving

Calculated for the housing company in the previous example, with all ten cars charging all night. Consumption estimate 18 kWh/100 km. In reality, some cars fill up earlier, leaving even more power for the rest.

Solution

How KotiCharge load management works

EV charging load management runs automatically in the background. Neither the board nor the residents need to do anything.

1

Measurement

The building's total consumption is measured in real time at the main switchboard — per phase, so uneven loads are accounted for too.

2

Calculation

KotiCharge continuously calculates how much main-fuse capacity is free, leaving a safety margin for sudden load changes.

3

Power allocation

The KotiCharge cloud service distributes the free power to charging cars via OCPP — regardless of charger brand. When one car is full, its power moves automatically to the others.

4

Multi-level monitoring

Limits are monitored at the main-fuse, charging-group and individual-charger level, so no part of the electrical system is overloaded.

Plus: a power cap for peak hours

Besides protecting the main fuses, total charging power can be capped, for example between 7 am and 9 pm. EV charging then doesn't raise the building's power peak or the housing company's power charge — and any power charge that does arise is allocated to the residents who caused it.

Power-charge allocation

Cloud-based OCPP load management

One load management system, many charger brands — on the same line

Chargers serve a housing company for 10–15 years, but individual models leave the market much sooner. KotiCharge load management runs in the cloud over the OCPP standard, so it isn't tied to any manufacturer.

Manufacturer's own load management

All chargers from one manufacturer — forever

  • Load management only works between devices from the same manufacturer
  • When a model is discontinued, compatible new chargers may no longer be available
  • Expanding may require a separate charging group, its own power reserve or replacing the whole system
  • The housing company can't freely put equipment out to tender

KotiCharge cloud-based load management

Always choose the best charger on the market

  • Chargers from different brands on the same connection, under the same power limit and in the same load management
  • Works with any charger that supports OCPP 1.6J or newer
  • When a model is discontinued, any OCPP device can be your next charger
  • Expand gradually — new charge points join the same load management

Example — one main switchboard, three charger brands

Main switchboard

3 × 100 A

One shared power limit

2022

Chargers A

6 units — original purchase

2025

Chargers B

4 units — model A no longer sold

2028

Chargers C

8 units — best price on the market

All 18 chargers share the same main-fuse capacity, and KotiCharge controls them as one system. The board doesn't need to worry whether compatible add-ons are still available for the old devices.

Benefits

Why dynamic load management pays off for housing companies

Main fuses never trip

Total charging power always stays within the connection limits — even on a freezing evening when saunas, stoves and heating are all on at once.

No costly connection upgrade

When charging power follows the actual free capacity, the existing grid connection often goes a long way — without connection fees or a switchboard renovation.

More charge points on the same connection

The charging system grows with the number of EVs. New charge points join the same load management, and each addition doesn't need to be re-sized for the worst-case peak.

Faster charging at night

When the rest of the building uses little power, chargers get many times more power than with a fixed limit. Cars are ready in the morning.

Keeps the power charge in check

A peak-hour power cap stops EV charging from raising the building's monthly power peak — and with it the housing company's electricity bill.

Different brands on the same line

Cloud-based OCPP load management controls chargers from different manufacturers on the same grid connection and under the same power limit. The housing company can always choose the best device on the market.

“Their multi-level load management keeps both the charging circuit and our campus main power line within safe limits at all times — an absolute requirement for us, given the critical equipment on site that cannot tolerate any downtime.”

Planning

Load management doesn't replace good planning — but it makes it pay off

Dynamic load management isn't magic. It doesn't create extra capacity — it puts to use what the connection already has. To get the full benefit, the charging cabling must have no bottlenecks, and the system should be sized for the future.

Checklist for the board

  • Is the building's total consumption measured at the main switchboard?

    Dynamic load management needs real-time measurement. Without it, you have static load management.

  • Will the system still work when half the cars are EVs?

    Ask the supplier for a calculation where 50% — and later 100% — of parking spaces are used for charging.

  • Are there bottlenecks in the cabling?

    Daisy-chained cable groups can prevent free capacity from being used, even when the connection has room.

  • Is load management tied to one charger brand?

    If load management is the manufacturer's own, all future chargers must be bought from the same manufacturer. Cloud-based OCPP load management works with any brand.

Common questions

Frequently asked questions

What is dynamic load management?
Dynamic load management measures the building's electricity use in real time and gives the chargers only the power that is currently free on the grid connection. When other consumption rises, for example in the evening or during a cold snap, charging power is reduced automatically. When consumption drops, for example at night, cars get more power. The main fuses never overload, and the full capacity of the connection is put to use.
What is the difference between static and dynamic load management?
Static load management reserves a fixed total power for the chargers, sized for the building's worst consumption peak — and the system doesn't know what the rest of the building is using. Dynamic load management follows the building's actual load and adjusts total charging power continuously. That is why dynamic load management fits more charge points on the same grid connection, and cars charge faster.
Should a housing company install 22 kW chargers if it has load management?
Yes. Most chargers support 22 kW, and charging speed is usually limited by the car (typically 11 kW). With load management, the car charges at full power whenever the connection has room, and at busy times power is shared fairly.
Does load management slow down EV charging?
Only briefly, and only when the connection is otherwise at capacity — typically on weekday evenings. In housing companies, cars usually stay plugged in overnight, when other consumption is low and load management gives them more power. In practice, cars are charged by morning even if power was limited for a while in the evening.
Can chargers from different brands share the same load management?
Yes. KotiCharge load management runs in the cloud over the OCPP standard, so any charger supporting OCPP 1.6J or newer — such as Zaptec, Easee, Garo, Defa, Alfen, Keba and Charge Amps — can be connected to the same grid connection and the same load management. All chargers share the same main-fuse capacity regardless of manufacturer. Dynamic load management also requires measuring the building's total consumption at the main switchboard — we assess your site free of charge.
What happens if our charger model is discontinued?
Nothing to worry about. With a manufacturer's own load management, new chargers usually have to be the same brand — and if the model is discontinued, expanding may require replacing the whole system. KotiCharge's cloud-based load management isn't tied to any manufacturer, so any OCPP-compatible device can be your next charger, and it joins the same load management alongside the existing ones.
Does load management help reduce the housing company's power charge?
Yes. In addition to protecting the main fuses, KotiCharge load management can apply a power cap during peak hours, so EV charging doesn't raise the building's monthly power peak. If a power charge still arises, KotiCharge allocates the EV share to the residents who caused it rather than to the whole housing company.
