Product Introduction to the Integrated Industrial and Commercial Liquid-Cooled Energy Storage Cabinet

Part One: Product Overview  

This energy storage cabinet is an integrated, intelligent battery energy storage system specifically designed for industrial and commercial applications. The system adopts a highly integrated design, seamlessly integrating the battery pack, high-voltage control, power converter, energy management system, thermal management, and fire safety systems into a single standardized outdoor enclosure. It features high safety, high energy density, long service life, and easy installation and maintenance.

Part Two: System Architecture and Internal Components  

The interior of the energy storage cabinet features a scientifically designed zoned layout and is primarily composed of the following core components: the battery system employs… 4 The high‑performance lithium iron phosphate battery modules are arranged in a vertical, stacked configuration. The high‑voltage box and the distribution layer centrally manage the safety protection of the high‑voltage DC circuit, including the main circuit breaker and liquid cooling, BMS 、 PCS , branch circuit breakers for outlets, etc. The energy storage converter enables bidirectional conversion between DC and AC power, supporting three-phase AC input and output. Thermal management and environmental control are ensured by a liquid‑cooling unit that precisely regulates battery temperature differentials, complemented by an industrial dehumidifier to prevent moisture and condensation on internal electrical components. The safety and communication systems are equipped with aerosol‑based or total‑flooding automatic fire suppression systems, along with backup… UPS Power supply, integrated energy management system, and 4G The antenna supports intelligent scheduling and cloud-based monitoring. An emergency stop button is integrated on the exterior of the cabinet and within the control circuit, ensuring one‑button power shutdown in emergency situations.

Part Three: The Core Control Brain ( CCU )

The cabinet is equipped with professional CCU1 As the control hub, the central control unit boasts robust control and monitoring capabilities: it features comprehensive sampling interfaces for both battery‑level and module‑level voltage measurements, enabling real-time tracking of system status. It also integrates a wide array of communication interfaces. PCU_CAN、RS232 , as well as multiple channels that respectively connect the operation control unit, smart meters, and general-purpose peripherals. RS485 Interface, enabling efficient system-wide coordination. Logic and execution control support output of status feedback and control drive for DC contactors, providing… 12V and 24V Switching is enabled, with multiple backup channels available. Peripheral integration is provided. BMS Power supply, charging gun cable control interface, and LED Status indicator interface, fully supporting integrated solar‑storage‑charging applications.

Part Four: Technical Specifications and Parameters  

The cell type is lithium iron phosphate. The DC voltage range is 671 Volt DC to 864 DC voltage. Cooling is achieved via liquid cooling. The protection rating is IP55 , featuring high‑level water and dust resistance to meet the demands of outdoor installation. The operating ambient temperature ranges from below zero… 20 Celsius to 55 between degrees Celsius, 50 Derated operation above °C. The ambient humidity requirement is 0 To 95% Relative humidity. The maximum operating altitude is 2000 m. Fire protection is provided by aerosol or total flooding automatic fire suppression systems.

Part Five: Physics and Airflow Design  

In terms of airflow architecture, the energy storage terminal employs an advanced ventilation and heat‑dissipation design featuring front‑side air intake and rear‑side exhaust. The cabinet door is equipped with inlet louvers on the front, while corresponding exhaust vents are provided on the back. Combined with internal liquid cooling and fans, this configuration establishes an efficient, unobstructed air circulation loop, effectively preventing localized heat buildup. In terms of appearance and structure, the entire cabinet is constructed from a robust, weather‑proof metal enclosure. The base incorporates dedicated forklift‑compatible openings and mounting foot brackets, facilitating on‑site lifting, installation, and precise positioning.
