Dynamic Load Management
EV Charging that respects your building’s power limits, in real time.
Apartment buildings have a finite electrical capacity. Dynamic Load Management (DLM) is the controller that lets you add EV charging without re-engineering the supply — measuring four levels of building demand and adjusting charging continuously to stay safely within them.
EV charging that needs no new supply infrastructure.
Every building has a fixed amount of power to draw on. Lifts, lights, pumps, hot water, air conditioning, and cooktops are already using most of it, and that demand rises and falls at predictable times of day.
Dynamic Load Management (DLM) measures the building's total power use in real time and fits EV charging into whatever capacity is actually free.
When the building gets busy, charging slows or pauses. When demand drops, usually overnight, charging ramps back up. The building's supply limit is never exceeded.
That is why most buildings can add ReadySteadyPlug with no switchboard or supply upgrade.
Understanding load management
-
Non-balanced load
Uncontrolled charging stacks onto peak demand and overshoots the building limit.
-
Static load management
A fixed cap can still peak over the limit – and wastes capacity off-peak.
-
Dynamic Load Management
Charging flexes in real time to fill every spare KW – and never exceeds the limit
What changes when the controller is awake.
Technical specs
In this real-world example, the RSP Energy Metering solution is implemented at four (4) connection points. Mains board (1) is metered, as well as House board (2) and Sub-house boards (3 & 4) as they all provide supply to non-EV loads also. Load of every EVDB is calculated and managed by the CPMS for DLM, with each charge point individually metered within the EVDB.-

OC-defined tariff schedules supported (single, ToU, multi-tariff)
Remote firmware updates
The same controller, three very different wins.
FOR OWNERS CORPORATIONS
No expensive upgrades
DLM is the reason a switchboard or supply upgrade is avoidable in most buildings. Charging works within the capacity you already have — so the single largest line item is gone before the AGM discussion even starts.
FOR BUILDING & SITE MANAGERS
Full visibility on load over time
The platform shows peak load and load patterns across the whole site. That same data opens the door to actively managing maximum-demand charges.
FOR INSTALLERS
Easy to deploy
Metering is deployed at the mains, common mains and sub-mains as the site requires, with per-EVDB limits and live per-phase visibility. Capacity is measured before the solution is designed — not assumed.
Frequently Asked Questions
-
No. DLM continuously monitors the building’s total load and adjusts charging in real time so the supply limit is never exceeded. If building demand rises, EV charging reduces automatically.
-
Charging may slow or pause briefly during the building’s peak periods, then resume automatically. Because most charging happens overnight when building demand is lowest, residents typically notice nothing.
-
In most buildings, no. DLM works within existing capacity, and a site assessment confirms the building’s actual headroom before anything is installed.
-
Talk to us. The metering and DLM solution can be installed first to measure the building’s real load profile before any EV decision is made.
-
Under one second. The controller polls every metering point continuously and re-allocates charging across active sessions on each cycle — drivers see at most a lower charge rate, never a failed session.
-
The EVDB keeps running locally on its commissioned safety profile and will not exceed the configured limits while offline. Connectivity is for billing and telemetry — not for safety.
Real events. Real responses. Sub-second decisions.
Building waking up
Common load 84 kW, well below the safe ceiling. All 9 active chargers run at their target rate. Headroom: 211 kW.
Lift bank starts morning cycle
Common load rises to 152 kW over 6 seconds. The controller sees the change at the common-property board before it reaches the sub-board.
EV charging eases
Within one polling cycle the EVDB reduces total EV draw from 122 kW to 91 kW. No charger drops below its minimum. No driver sees a session error.
Morning peak clears
Lift activity falls to baseline. Common load drops to 96 kW. EV charging ramps back to its target rate over the next 8 seconds.
Dinner peak protected
Combined common + house demand approaches 280 kW. EVs throttle to 28 kW (≈ 2.3 kW each across 12 active chargers) — keeping building total under 92% of ceiling.
Off-peak window opens
Common load returns to nighttime baseline (62 kW). Scheduled charging resumes at full rate. Most residents complete their day's charge between now and 06:00.

Energy metering and DLM are core parts of the ReadySteadyPlug charging system — and they're also offered on their own, for buildings that want metering and load visibility without (or before) EV charging.
Deployed in real buildings
160 lots · North Ryde, NSW
At this 160-lot building, RSP Energy Metering monitors the mains, common mains, and two sub-mains separately — with every charge point individually metered, ready to balance load as demand grows.
