Dynamic Load Management

Dynamic load management is a sophisticated feature that empowers users to efficiently control electric load by managing a group of chargers installed within a single circuit. Through the implementation of modbus RS-485 communication, the chargers are able to communicate with one another and dynamically adjust their charging power in response to the load on the grid, ensuring optimal charging operations and grid stability.

DLM Types

Dynamic load management (DLM) is a versatile solution applicable in various scenarios, providing users with the flexibility to choose between using it with or without a smart meter. Here are the key distinctions:

DLM with smart meter: This configuration enables users to efficiently manage the electric load between chargers and other electronic devices. By leveraging the capabilities of a smart meter, precise control and optimization of the overall load can be achieved.

DLM without smart meter: In cases where the focus is solely on managing the electricity load between chargers and there are no additional electronic devices contributing to the load, this option can be utilized. It offers a simplified approach to load management, tailored specifically to charger interactions.

DLM Connection

Dynamic Load Management (DLM) is achieved through a carefully interconnected system of chargers, where communication is governed by a designated "Master" charger, dictating instructions to the remaining "Slave" chargers. These chargers can be interconnected either in a serial or parallel manner, each requiring the use of UTP twisted pair cables for communication via the A and B pins.

Teltonika Energy App Settings

Once the chargers are properly connected to the electrical grid and interconnected to each other, the next step is to configure the settings for each charger using the Teltonika Energy app. Below, you will find a comprehensive list of the settings that should be adjusted to achieve DLM functionality:
