Battery Energy Storage System (BESS)

Battery Energy Storage System (BESS) is a system that stores electrical energy through batteries and releases it when needed. It is widely used in power systems, renewable energy integration and user-side energy management. Its core functions include energy time shifting (peak shaving and valley filling), frequency regulation, backup power supply, etc.

Core components:

• Battery pack: Energy storage unit, composed of multiple battery cells connected in series and parallel.
• Battery Management System (BMS): Monitors battery status (voltage, temperature, SOC) to ensure safety and life.
• Power Conversion System (PCS): Realizes bidirectional conversion between DC and AC, and connects to the grid or load.
• Control System: Optimizes charging and discharging strategies to respond to grid or user needs.

ARMxy can be used as an EMS Embedded Computer, battery analysis unit (BAU) or Embedded Controller, and can achieve seamless communication with devices such as battery management system (BMS), power conversion system (PCS), Air conditioner, meter and display. ARMxy is combined with BLIoTLink Protocol conversion software , which support Linux, Ubuntu and various industrial protocols, including Modbus, IEC 61850, IEC 104 and DNP3. This ARM Embedded Computer is used in battery energy storage system (BESS) and has flexible and optional multi-interface communication management to improve operational efficiency and help enterprises achieve energy management goals.

Flexible connection and management: multiple interfaces for free selection

ARMxy not only has stable performance, but also has very flexible interfaces. It supports multiple interfaces for flexible combination. We provide 39 IO boards, and users can configure more than 50,000 combinations by themselves.

• DI: Connect smoke sensors, water immersion, infrared sensors, etc. to monitor the environmental changes of energy storage cabinets in real time to ensure safety.
• DO: can control external devices such as switches and lights to facilitate intelligent equipment management.
• RS232/ RS485: communicate with dehumidifiers, liquid coolers and other equipment to ensure stable and accurate data transmission of equipment.
• LAN port: connect monitoring equipment such as cameras to achieve remote monitoring and control.
• CAN port: communicate with high-voltage boxes to ensure the safe operation of high-voltage equipment, prevent overload or failure, and provide a wide range of monitoring and control functions.

In addition, ARMxy also provide AI, AO, RTD, and TC acquisition modules. Flexibility to meet the needs of battery energy storage systems (BESS) and other industrial automation applications.

Flexible expansion and multi-protocol support

ARMxy has optional MCU, RAM, ROM and hardware interfaces, Ethernet, WiFi and 4G communication methods, and HDMI interface for connecting to display screens, which enables real-time data visualization and interaction to enhance monitoring and control. These features make it a scalable and future-proof solution for battery energy storage systems (BESS) and other industrial automation scenarios.

ARMxy has comprehensive communication protocol support to ensure wide compatibility across different systems. Supported energy protocols can be used in energy management systems, including power communication protocols such as Modbus, IEC 61850, IEC 104, DNP3 and DL/T 645, which can achieve seamless interaction with battery energy storage systems (BESS) and grid infrastructure. In addition, it also supports protocols such as MQTT, OPC UA and BACnet, which can be easily integrated into the IoT ecosystem. For automation and control, ARMxy can communicate smoothly with various PLC systems. This wide range of protocol support ensures interoperability, making it an ideal solution for industrial automation and smart energy management applications.

Industrial-grade reliability for harsh environments

ARMxy full-interface isolation design. Whether it is the Ethernet port, serial port, or DI, DO port, all interfaces are isolated and protected. Especially in the energy storage system, we need to communicate with equipment such as dehumidifiers, liquid coolers, electric meters and air conditioners, and isolation protection is particularly important. Because energy storage equipment usually involves high-frequency data transmission and access to strong electric equipment, the slightest carelessness may cause equipment damage or even burn the host. Through these isolation designs, the ARMxy that the energy storage system can operate stably in harsh environments and avoids potential failures and equipment damage.

ARMxy has multiple interfaces, flexible expansion options, multi-protocol support and rugged industrial design, making it an ideal embedded computer solution for energy storage systems (BESS).
