With the speeding up of the global energy transition, energy storage devices have been playing the role of balancing power supply and demand and improving the utilization rate of clean energy. Huijue New Energy provides differentiated products to different application scenarios with its liquid and air cooled energy storage systems in this market. Today, Xiaobian will sort out the technical characteristics, performance and application scenarios of the two, and provide a reference for the owners of business owners to choose the best solution.
Liquid-cooled energy storage, in common language, to equip a 24-hour air-conditioned room inside the battery cell, its heat dissipation performance is stable and efficient, has become the standard configuration of large-scale energy storage. Huijue's HJ-ESS-DESL series has good temperature control inside the battery cluster through advanced liquid cooling cycle design, and temperature difference is controlled within ±2℃. It significantly improves the stability of the system, especially under high load or high temperature conditions, and avoids performance degradation caused by battery overheating.
From a capacity point of view, the series is modularly expandable and suitable for applications with high and continuous power demand, such as business parks and data centers. Its efficiency of system is as high as 90%, with 80% deep discharge (DOD), more than 6000 cycle life design, and cutting the life cycle electricity cost (LCOS) by about 20%. In addition, the combined smart energy management system can be smartly combined with the power grid or photovoltaic/wind power generation system and customer's real situation to carry out multi-mode operation such as peak cutting and valley filling and demand management.
From the safety point of view, the liquid cooling system reduces thermal runaway risk to the industry's lowest level by having redundant protection measures (e.g., overcharge protection, short circuit isolation) and intelligent thermal management algorithms. Along with a 20-year design life, it is the preferred solution for high reliability and long cycle investment.
The air cooling system is maintenance friendly and structurally simple, and plays an important role in small and medium-sized energy storage. Huijue's air cooling series adopts adaptive air cooling strategy to dynamically adjust fan speed and air duct configuration according to real-time load, not only saving energy at low load, but also dissipating heat rapidly at peak power consumption and saving battery component loss.
This suite is more suitably applied to distributed photovoltaic power plants, charging stations or small and medium-sized commercial businesses. Its strong point is its great compatibility with renewable energy - the AI energy optimization engine embedded in the system can interpret the photovoltaic power generation curve, price fluctuation and load demand, and automatically convert the best power supply mode to help users improve their energy self-sufficiency rate by more than 30%. For example, solar energy is saved preferentially during the period of sufficient light and offloaded during the peak period of grid electricity prices to have maximum economic return.
From the perspective of safety design, air-cooled system ensures stable operation in harsh environments through fire isolation chamber, thermal runaway warning module and real-time diagnosis function. Although the air-cooled system's cycle life (about 4,000 cycles) is slightly lower than that of the liquid-cooled solution, its lower initial investment and maintenance costs make it appropriate for applications requiring rapid returns.
Efficiency of temperature control
The liquid cooling system comes in direct contact with the cell through the liquid medium, and heat dissipation efficiency can be more than 40% compared with air cooling, especially for high-temperature and high-humidity or closed conditions.
The air-cooled system relies on air convection, which is disadvantageous when ambient temperature varies a lot, and redundant designs more need to be abandoned.
economy
The initial cost of liquid cooling is higher, but it saves money on the long cycle due to the life and efficiency gains.
The deployability of the air cooling system in flexible fashion is suitable for low-budget or aggressive growth projects.
sustainability
The liquid cooling system may warm the building through waste heat recovery to improve overall energy efficiency.
The air-cooled design is less complex in structure, the components are less cumbersome to be recycled, and the life-cycle carbon footprint is reduced by 15%.
Large grid-scale industry and grid-scale energy storage: Choose liquid cooling for the demands of stable operation, high capacity and long duration.
Small and medium businesses and distributed power: Air-cooled solutions have the ability to make the maximum utilization of economic payback and renewable power due to flexible deployment and AI-driven smart scheduling.
Thanks to diversified design of air cooling and liquid cooling technology, Huijue New Energy not only caters to diversified market demand, but also propels the energy storage industry into efficient and sustainable direction with safe and intelligent innovative design. With the breakthrough in temperature control technology and material technology in the future, the two systems are supposed to integrate more strengths and provide enterprises with an even better paradigm of energy management.
