As electric vehicles become increasingly popular you’ll likely encounter the term “dynamic load management” when exploring charging solutions for your home or business. But what exactly does this technology do and why should you care about it?
Dynamic load management (DLM) is a smart technology that automatically balances the electrical power distribution between multiple EV chargers and other electrical devices in your building. As an advanced method for managing and optimizing energy distribution, DLM acts like an intelligent conductor that ensures your electrical system doesn’t become overloaded whilst maximising the available power for charging your vehicles.
Whether you’re managing a fleet of company vehicles or planning to install multiple charging points at home this technology could save you thousands in electrical infrastructure upgrades. It’s revolutionising how we approach EV charging by making it more efficient accessible and cost-effective than ever before.
Understanding Dynamic Load Management for EV Chargers
Dynamic load management operates as an intelligent power distribution system that continuously monitors and adjusts electrical loads across your charging infrastructure. The technology ensures optimal charging speeds whilst protecting your electrical system from overload conditions, and it constantly optimises charging to maintain efficiency and reliability.
How It Works
Dynamic load management monitors your building’s total electrical consumption in real-time through integrated sensors and smart meters, with real time monitoring as a key feature of the system. The system calculates available capacity by subtracting current usage from your maximum electrical supply capacity—typically 100A or 200A for commercial properties.
Your EV chargers receive power allocation based on four primary factors:
- Available electrical capacity after accounting for building loads
- Number of vehicles actively charging
- Priority settings configured in the management software
- Individual demand of each vehicle
The system adjusts charging rates every 10-30 seconds depending on manufacturer specifications. When electrical demand increases—such as when air conditioning units activate during summer months—the DLM automatically reduces EV charging power to maintain safe operating levels.
For example, if your facility has 80kW total capacity and building operations consume 50kW, the DLM allocates the remaining 30kW amongst connected EVs. Three vehicles charging simultaneously each receive 10kW, but if one completes charging, the system redistributes that power to the remaining two vehicles at 15kW each.
Key Components and Technology
Current Transformers (CTs) measure electrical flow at your main distribution panel with accuracy ratings of ±1%. These sensors clip around electrical cables without interrupting service and transmit readings every 250 milliseconds to the control unit.
Central Control Unit processes data from all connected devices using embedded microprocessors capable of 1,000 calculations per second. The unit connects via Ethernet, Wi-Fi, or 4G cellular networks to communicate with charging stations using protocols like OCPP 1.6 or OCPP 2.0.1.
Smart Charging Stations equipped with internal controllers respond to power adjustment commands within 2 seconds. Modern units support charging rates from 1.4kW to 22kW for AC charging and up to 350kW for DC rapid charging.

Types of Dynamic Load Management Systems
Dynamic load management systems come in two primary configurations that suit different operational requirements and infrastructure scales. Each type offers distinct advantages depending on your facility size, connectivity options and management preferences.
Local Load Management
Local load management operates entirely within your site’s boundaries using dedicated hardware and software components. The system connects directly to your chargers and energy meters without requiring internet connectivity or external communications. Current transformers measure electrical flow at your main supply point whilst the control unit processes this data locally to adjust charging speeds in real-time. The grid connection point is crucial here, as it determines the maximum available power for your site, allowing the local DLM system to manage load distribution efficiently and safely.
Your local DLM system responds instantly to power demand changes because all processing occurs on-site. The hardware detects when additional EVs connect to chargers and immediately recalculates available capacity across all charging points. This configuration proves particularly effective for facilities with 2-10 charging stations where external connectivity presents challenges or security concerns exist.
Installation involves mounting current transformers at your electrical panel and connecting them to a local control unit that communicates with smart chargers via hardwired connections or local wireless protocols. The system operates autonomously once configured and continues functioning even during internet outages. Smaller commercial properties like office buildings with dedicated parking or residential complexes with shared charging facilities benefit most from this approach.

Fleet operators controlling 50+ vehicles benefit from centralised reporting that tracks energy costs per vehicle and identifies usage patterns. The system scales effortlessly as you add charging points—simply connect new chargers to your network and the cloud platform automatically incorporates them into the load management scheme.
Data analytics provided by cloud platforms reveal charging trends that inform expansion decisions and maintenance schedules. Your system generates detailed reports showing peak usage times, average session durations and total energy delivered across specific timeframes. Enterprise clients typically achieve 25-40% better utilisation rates compared to standalone systems through cloud-based optimisation features.
Implementation Considerations
Dynamic Load Management requires careful planning to integrate seamlessly with your existing electrical setup. Your implementation strategy determines the system’s effectiveness in optimising power distribution across multiple EV chargers. Incorporating DLM is essential for supporting scalable and efficient EV infrastructure, ensuring that charging networks can grow sustainably while overcoming grid limitations.
Installation Requirements
Installing DLM involves integrating smart chargers with a central load management controller that monitors your property’s total power usage, ensuring a stable and sufficient power supply for optimal DLM operation. The system requires DLM-capable chargers equipped with communication interfaces and a software platform that dynamically controls charging rates based on real-time demand.
Your installation process starts with deploying Current Transformers (CTs) at the main electrical panel to measure power flow continuously. These sensors connect to the central controller which processes data and sends commands to individual charging stations. Communication protocols like OCPP (Open Charge Point Protocol) enable remote monitoring and control of your charging infrastructure.
The electrical infrastructure you currently have often supports DLM installation without costly upgrades. DLM optimises your existing capacity rather than requiring an increase in supply from the grid. A typical installation for 10 charging points costs £2,000-£5,000 for the management system compared to £15,000-£30,000 for traditional electrical upgrades.
Your DLM system accounts for all electrical loads at the site including:
- Building services (lighting, HVAC, lifts)
- Industrial equipment and machinery
- Neighbouring facilities sharing your grid connection
- Seasonal variations in power demand
Compatibility with Existing Infrastructure
DLM systems retrofit to existing charging setups when your chargers support smart communication interfaces. Compatibility depends on each charger’s ability to modulate power output and interface with the load management system through protocols like Modbus, OCPP 1.6, or OCPP 2.0, and applies to both AC and DC chargers.
Legacy chargers without smart capabilities require replacement or upgrading to enable DLM functionality. Modern chargers from manufacturers like ABB, Schneider Electric, and ChargePoint, including DC chargers, feature built-in DLM compatibility. The system adapts to residential installations with 2-3 chargers, commercial properties with 10-50 stations, and fleet depots managing 100+ charging points, supporting both AC and DC chargers.
Your existing electrical panel capacity determines the number of chargers DLM can support, allowing you to efficiently manage multiple charging stations:
Panel Capacity | Traditional Setup | With DLM | Increase |
|---|---|---|---|
100A | 2-3 chargers | 4-5 chargers | 67% |
200A | 4-6 chargers | 8-10 chargers | 66% |
400A | 8-12 chargers | 16-20 chargers | 66% |
The system integrates with renewable energy sources like solar panels and battery storage systems. DLM prioritises green energy when available and switches to grid power during periods of low renewable generation. This integration reduces your operational costs by 15-25% through optimised energy sourcing.
Dynamic Load Management vs Static Load Management
Understanding the differences between dynamic and static load management helps you select the optimal charging solution for your specific requirements. Dynamic load balancing plays a crucial role in optimizing energy usage and maintaining grid stability by efficiently distributing electrical loads in real time. Each system offers distinct advantages depending on your charging infrastructure size and usage patterns.
When considering efficiency or managing peak demand, techniques like load shedding can be implemented to reduce energy demand during high-usage periods, helping to avoid peak electricity charges by temporarily lowering or pausing non-essential loads.
Power Allocation Methods
Dynamic load management adjusts power distribution in real-time based on actual consumption and available capacity. The system continuously monitors electrical loads and redistributes power between chargers every few seconds, with methods tailored for EV chargers based on demand and prioritization. Static load management assigns fixed power limits to each charging point during installation. These predetermined allocations remain constant regardless of actual demand or available capacity.
Flexibility and Adaptability
DLM systems respond instantly to fluctuations in electrical demand and supply. Your chargers automatically receive more power when other electrical loads decrease or when fewer vehicles connect for charging. The system adapts to varying charging patterns throughout the day and optimises power distribution during peak and off-peak periods.
Static systems maintain fixed power allocations without adjustment capabilities. Each charger operates at its preset limit even when additional capacity becomes available. This approach works effectively for predictable charging scenarios with consistent usage patterns.
Efficiency Comparison
