The air-cooled industrial energy storage system with 130 kW power and 257 kWh capacity is designed for applications requiring both high reliability and flexible operation. It combines lithium-ion battery technology with intelligent control and safety systems in a compact, modular enclosure suitable for a wide range of industrial and commercial sites.The system’s rated power of 130 kW enables it to support various grid and facility-level functions, such as peak shaving, load shifting, and demand response. With a usable energy capacity of 257 kWh, it can discharge at rated power for approximately two hours, making it suitable for short- to medium-duration applications including backup support, optimization of on-site renewable energy, and stabilization of sensitive loads.An air-cooled thermal management design is adopted to maintain the batteries within an optimal temperature range. High-efficiency fans, ducting, and temperature sensors are used to achieve uniform cooling across all battery modules. This approach simplifies structure and maintenance compared to liquid-cooled systems, while reducing risk of leaks and easing installation and operation in a variety of environments. The control system dynamically adjusts fan speed according to real-time temperature and load conditions, thus balancing cooling performance with energy consumption and noise.The battery pack is composed of high-energy-density modules configured to meet the required system voltage and capacity. Each module is monitored by a battery management system that tracks cell voltage, current, temperature, and state of charge. At the system level, an energy management controller coordinates charging and discharging, communicates with external control platforms, and supports automatic, scheduled, or remote dispatch. Various communication interfaces and standard protocols are provided to facilitate integration with building management systems, microgrids, and renewable energy sources such as solar or wind.Safety is addressed through multiple layers of protection. Hardware and software protections include over-voltage, under-voltage, over-current, short-circuit, over-temperature, and insulation monitoring. Fire detection and fire suppression interfaces are reserved, and the enclosure is designed to limit thermal propagation between modules. The system is typically compliant with relevant electrical and safety standards for industrial energy storage.The cabinet structure is suitable for both indoor and outdoor deployment, with options for weatherproof and dustproof construction. Modular design allows parallel connection of multiple units to scale up power and energy according to project needs. This 130 kW / 257 kWh air-cooled solution can thus serve in scenarios such as factory load management, commercial building peak reduction, small microgrids, data center support, and charging infrastructure buffering, improving overall energy efficiency and power quality while reducing operating costs.
