In today’s wave of intelligent technologies reshaping industries worldwide, energy storage systems are no longer just “boxes that store electricity.” They are becoming smarter—able to monitor battery conditions in real time, receive dispatch commands, and interact with cloud platforms. Behind this intelligence is an invisible yet essential component within every system: communication protocols.

01 Communication Protocols · The Key to “Understanding Each Other”

A communication protocol is the set of rules and “language” devices use to exchange information. In an energy storage system, components such as the battery, BMS, EMS, inverter, and monitoring platform must “speak the same language” to work together and make the best use of system resources.

· Multi-device interconnection: Efficient exchange of critical data such as battery status, voltage/current, and temperature.

· Remote monitoring & O&M: Data synchronization with cloud platforms to enable fault warnings and remote commissioning.

· Compatibility & scalability: Standardized protocols make it easier for devices from different brands and suppliers to interoperate.

02 Local vs. Remote Communication

Communication in energy storage systems typically falls into two categories: local communication and remote communication.

· Local communication: Devices connect via interfaces such as RS485, CAN, and LAN for efficient internal coordination.

· Remote communication: Data is transmitted to the cloud via Wi-Fi, 4G/5G, or Ethernet to support remote monitoring and dispatch.

· User access: Users can view operating status, configure parameters, and manage the system through an app or web platform—enabling true “cloud control”.

In global deployments, standardizing communication protocols becomes especially important. It not only improves device compatibility, but also reduces integration and maintenance costs, and makes it easier to connect with various energy management platforms (EMS). This lays a solid foundation for scalable replication, overseas expansion, and efficient operation of energy storage systems worldwide.
