Dynamic load management: comprehensive guide to efficient infrastructure

With the boom in electric vehicles, one of the biggest challenges for businesses, hotels and condominiums is managing the increase in energy demand. Installing multiple charging stations without proper planning can lead to grid overloads, costly meter upgrades and service interruptions. One solution to this problem is dynamic load management (also known as Dynamic Load Management or DLM), a technology that optimizes the efficiency of charging stations.

What exactly is dynamic load management?

Dynamic load management is an intelligent charging system that automatically distributes and adjusts the available power among the various charging stations in real time. Unlike a static system, which assigns a fixed power to each charging station, the dynamic system is flexible and constantly adjusts to the energy needs of the entire infrastructure.

In practical terms, if the building's energy consumption suddenly increases (e.g., air conditioners turn on or industrial machinery comes into operation), the DLM system detects the increased load and momentarily reduces the power delivered to the charging stations to avoid exceeding the maximum capacity of the meter. As soon as the overall building consumption decreases, the power available for charging is restored to the highest possible level, always ensuring the fastest possible charging at that given time.

How dynamic management works: behind the scenes

At the heart of the system is a smart meter or current sensor, installed upstream of the system, which monitors the building's total energy consumption in real time. This device constantly communicates with charging stations through standard protocols such as the Open Charge Point Protocol (OCPP ), enabling centralized management.

The process consists of four operational steps:

1. Constant monitoring: the main meter measures, instant by instant, the total power consumed by the building, including all noncharging loads (lights, elevators, etc.).
2. Residual power calculation: the management software (the "brain" of the system) subtracts the building's instantaneous consumption from the maximum contracted power available at the meter. The result of this operation is the power actually available for charging electric vehicles.
3. Intelligent and automatic distribution: the system distributes the remaining power among all connected vehicles equally and intelligently. If only one vehicle is charging, it will receive all available power for fast charging. If multiple vehicles are connected, this will be distributed dynamically among them, ensuring that they all charge without causing a blackout.
4. Advanced priority management: more advanced DLM systems, allow priority rules to be defined. This allows power distribution to be tailored to specific criteria, such as:
   • First-In, First-Out (FIFO): the first vehicle to connect receives more power.
   • Priority based on state of charge (SoC): the vehicle with the lowest battery has priority.
   • Priority by user: more power can be assigned to specific users.

Why dynamic management is critical to your business

Adopting a dynamic load management system is not just a technological choice, but a strategic decision that brings concrete benefits:

• Overload prevention: prevents costly power outages and protects the electrical system.
• Cost savings: allows more charging points to be installed without necessarily requiring an onerous increase in meter power.
• Maximum efficiency: uses 100% of the available power, always ensuring the fastest possible charging under all conditions.
• Future scalability: a DLM system is designed to grow with your needs. Adding new charging stations in the future will be easier and cheaper.

In conclusion, dynamic load management is the "brain" that transforms a simple set of columns into a smart, reliable and future-ready charging infrastructure for electric mobility.

FAQ: What exactly is dynamic load management (DLM)?

Dynamic Load Management or DLM is not simply a feature, but an intelligent charging technology fundamental to any modern infrastructure. Its purpose is to optimally distribute a building's available electrical power among multiple electric vehicles charging at the same time. It functions as an energy "brain" that prevents overloads and ensures that the electrical system never exceeds its maximum capacity, all while maximizing charging efficiency.
