Battery Management System
BESS employs a sophisticated, multilevel battery management system (BMS) for system monitoring and control. Each battery management system including:
- Module Battery management unit (BMU)
- Rack battery management system (BCU)
At the lower level is the Module BMS (BMU), which is designed to detect voltage, temperature, and execute cell balance functions for cells. The rack BMS (BCU) can manage all module BMS units and detects total voltage, current, and executes protection functions by switching DC-contactor as well as interact with PCS by RS485 to perform power limits. Finally, local controller manages rack BMS units (BCU) and PCS. What's more, the local controller reserve the Ethernet port (default) or the Cabinet equipped with 4G module (optional) connect the cloud platform or App for customer's real time monitoring.

- Components inside the high voltage box
- Air conditioning
- EMS control system
- PCS system
- Other auxiliary power supply equipment
Controller
To offer a universal interface for communication between iCON All-in-one systems and SCADA or EMS and release EMS from basic system protection, we deploy a local controller as part of the BESS integration.
- Control integration of the battery system (include battery BMS, cooling units, PCS etc.)
- Offer a universal interface for communication between All-in-one systems and SCADA or EMS.
- Supports RS-485, CAN, dry contact, Ethernet communication and easy integration
- Data logging (short period) for trouble shooting

Communication Topology
Liquid Cooling System
The liquid cooling system is small in size and equipped on each rack.
Advantages of Liquid Cooling
Higher cooling capability
compare to air cooling, liquid cooling is capable of taking more heat away from batteries under the same condition. And liquid cooling is the best choice when thermal density is beyond the capability of air cooling.
Better temperature uniformity
Cooling liquid has a specific heat capacity which leads to a smaller temperature rise during the cooling process. Therefore, battery cells will have a smaller temperature difference with liquid cooling.
Lower Noise Emission
Without fans on battery modules for air cooling means no noise emission from battery modules.
Working principle of Liquid Cooling
Working principle of Liquid Cooling
Battery Cooling
Cooling liquid powered by the pump will circulate inside battery modules and take the heat from batteries. When the liquid gets out of the battery modules, it became hot liquid with the heat from batteries. The hot liquid will circle back to a heat exchanging tank.
Heat Exchanging
Inside the heat exchange tank, the refrigerant will vaporize from liquid state to gaseous state. During this state/phase change process, the refrigerant will absorb a huge amount of heat from the battery cooling liquid and cool down the cooling liquid.
AC Cooling
The rest of the system is a standard Air Conditioner which releases the heat to the environment through the phase change of the refrigerant.
Fire Suppression and Detection System
Type of Fire Protection
The outdoor cabinet has a separate and relatively sealed space. According to the working principle of the energy storage system and other related technical characteristics, aerosol fire extinguishers and smoke detectors are installed. The fire extinguisher will automatically release aerosols and send a signal to the control panel when the internal temperature reaches 74 °C (162 °F). After releasing, the pressure sensor will send a signal to the Fire Control Panel to report the release event. In a separate loop, the smoke detector sends a signal to the control panel after sensing smoke. Smoke detection is normally reported before aerosol release. Upon receipt of either signal, the fire control panel sends an alarm to the fire mainframe and triggers a light and sound alarm.
Fire Detection & Suppression System Diagram
Aerosol Automatic Fire Extinguishers
When the temperature rises high enough, the extinguisher will automatically and efficiently generate and release an ultra-fine potassium-based aerosol with the assistance of a series of auxiliary components. With the collaboration of the patented design, the aerosol composition, and the ultra-fine particle size, the reaction between oxygen and combustible materials is greatly interrupted, thus ending the spread of flame.
Superior Performance vs. Gas Systems
Compared to gas fire extinguishing systems, aerosol offers higher performance than gas while using the same weight of the agent.
No Pressurized Vessels
Aerosol extinguishers require no pressurized vessels, pipes or other expensive components
Almost Maintenance-Free
Minimal maintenance requirements ensure long-term reliability and reduced operational costs
10+ Year Service Life
Extended service life of over ten years provides exceptional long-term value
Minimal Size & Weight
Compact design with minimal size and weight allows for flexible installation options
Highly Cost-Effective
All these advantages make aerosol fire extinguishers a highly cost-effective solution for fire prevention
Patented Technology
Ultra-fine potassium-based aerosol with patented design effectively interrupts combustion
