Empowering data communication in your BESS

Communication in Battery Energy Storage Systems

Communication and intelligent networking are key to an efficient Battery Energy Storage Systems (BESS) as they combine components from many different vendors and are themselves part of a networked smart grid. HMS solutions enable communication inside Battery Energy Storage Systems and integration into a wide range of applications. And also enables remote access to valuable data insights.

Battery Energy Storage Systems (BESS) network design

Connect communication standards and systems

Modern BESS systems contain a lot of different devices that communicate via different  protocols. Anybus network gateways from HMS Networks allow these devices to be easily networked. This enables central control but also access to data across all system levels.

  • Wide variety of supported protocols – CAN, CAN FD, BACnet, KNX, PROFIBUS, PROFINET, EtherNet/IP, Modbus.
  • Data access and interconnection for all types of equipment and systems. 
  • Choose the best components – regardless of manufacturer.

What is a Battery Energy Storage System (BESS)?

A Battery Energy Storage System (BESS) is a complex electrical system designed to store electrical energy in batteries and discharge it when needed. It serves various purposes, including grid stabilization, management of peak electricity demand, storing excess energy generated from renewable sources, and providing backup power in case of outages. BESS plays a crucial role in optimizing energy use, enhancing grid reliability, and enabling the integration of renewable energy sources into the power grid by smoothing out fluctuations in energy production and consumption. 

Why is networking of the different components in a BESS system important? 

Networking different components in a Battery Energy Storage System (BESS) is crucial for real-time monitoring, control, and optimization. It allows to interconnect devices of different vendors to a central control unit, enabling access to all system levels. Enabling efficient management of energy flow, state of charge, and overall system performance, ensuring reliability, maximizing efficiency, and enabling seamless integration with the grid and renewable energy sources.

Why is galvanic isolation in BESS systems crucial?

Galvanic isolation in BESS systems is essential to prevent electrical ground loops, ensuring safety and protecting components from voltage differences, thus reducing the risk of damage and electrical hazards.
