R&D

Driven by the global energy transition and the "dual carbon" goals, electrochemical energy storage systems are developing rapidly towards high power, high density, and large scale. As a core support for the stable operation of energy storage cabinets, temperature control technology directly determines battery life, system energy efficiency, and operational safety. With more than 20 years of experience in the energy storage field, UFO-POWER has focused on the R&D and iteration of liquid-cooled temperature control technology to address the pain points of traditional air-cooled technology, such as low heat dissipation efficiency, high energy consumption, and large temperature difference. It has formed a core technical solution with high efficiency, intelligence, and adaptability, providing solid support for the stable operation of energy storage cabinets in all scenarios.

As the core upgrade direction of energy storage cabinet temperature control technology, liquid-cooled technology has become the mainstream choice for high-power energy storage systems due to its advantages of high heat dissipation efficiency, precise temperature control, and low energy consumption. Based on market demand, UFO-POWER has created an independently developed precise liquid-cooled temperature control technology through architectural innovation, algorithm optimization, and process upgrading, realizing the full-chain layout from technological breakthrough to product landing, and solving the core problem of energy storage system performance degradation and service life shortening in high-temperature environments in the industry.

I. Core R&D Directions of Liquid-Cooled Temperature Control Technology

The R&D of UFO-POWER's liquid-cooled temperature control technology focuses on four core goals: "high-efficiency heat dissipation, precise temperature control, low energy consumption, and scenario adaptation". In response to the operational needs of energy storage cabinets in different scenarios, technical tackling is carried out from three dimensions: architectural design, component selection, and algorithm optimization to achieve all-round improvement of temperature control performance.

(I) R&D of Integrated Liquid-Cooled Architecture

Breaking through the shortcomings of scattered traditional liquid-cooled architecture and uneven heat dissipation, UFO-POWER has developed an integrated liquid-cooled architecture of "cold plate + fluid circulation", directly attaching the cold plate to the bottom of the battery module to achieve direct heat conduction and rapid heat dissipation, avoiding heat accumulation inside the battery cells. The cold plate flow channel design is optimized with a serpentine flow channel layout to increase the contact area between the cold plate and the battery cells, increasing the heat dissipation efficiency by 5-8 times compared with traditional air-cooled technology, and effectively solving the problem of a large amount of heat generated during the charging and discharging process of high-power energy storage cabinets.

At the same time, high-efficiency and environmentally friendly cooling fluid is selected, which balances thermal conductivity and safety, does not solidify at low temperatures and does not volatilize at high temperatures, adapting to the operational needs of different ambient temperatures; the fluid circulation system is optimized, using low-noise and high-reliability circulating pumps to reduce system energy consumption, making the energy consumption of the liquid-cooled system 60% lower than that of traditional air cooling, helping the comprehensive efficiency of the energy storage system to exceed 93.5%.

(II) R&D of Precise Temperature Control Algorithm

Relying on AI intelligent algorithm technology, UFO-POWER has developed an exclusive temperature control strategy to achieve precise control of battery cell temperature. Through high-precision temperature sensors, real-time data on battery cell temperature, ambient temperature, and charging and discharging power are collected. The algorithm automatically adjusts the cooling/heating power according to data changes. In winter, the PTC preheating function ensures the normal start-up of battery cells in low-temperature environments, and in summer, efficient cooling maintains the stable operation of battery cells, strictly controlling the battery cell temperature within the optimal operating range of 15-35℃.

In response to the characteristics of temperature fluctuations in different scenarios, the algorithm can automatically adapt and adjust. For example, in outdoor scenarios, it can dynamically optimize temperature control parameters according to day-night temperature differences and seasonal changes, and in industrial scenarios, it can cope with local high temperatures caused by equipment heat dissipation, ensuring that the energy storage cabinet can still maintain stable temperature in complex environments. At the same time, the algorithm has self-learning ability, which can continuously optimize the temperature control strategy according to the operation status of battery cells and environmental changes, further improving temperature control accuracy and energy-saving effect.

(III) R&D of Scenario-Adaptable Technology

Combined with the multi-scenario deployment needs of energy storage cabinets, UFO-POWER has optimized the integrated design of the liquid-cooled system and the cabinet, making the liquid-cooled system adapt to the IP65 high protection level, which can effectively resist the impact of dust, rainwater, corrosion and other harsh environments, and is suitable for deployment in outdoor, industrial workshops, large-scale power stations and other scenarios. For energy storage cabinets of different capacities such as household and industrial and commercial use, different specifications of liquid-cooled modules have been developed to achieve modular adaptation, which can be flexibly configured according to the capacity of energy storage cabinets, improving the versatility and practicality of the technology.

At the same time, the reliability design of the liquid-cooled system is strengthened, adopting a redundant backup mechanism to ensure that the system can still operate normally when a single component fails, avoiding safety hazards caused by temperature control failure; the pipeline connection process is optimized, using sealed connection to eliminate the problem of cooling fluid leakage, and improving the stability and safety of the system operation.

II. Technological R&D Achievements and Advantages

After continuous R&D and iteration, UFO-POWER's liquid-cooled temperature control technology has formed a mature product application scheme, with prominent core achievements and advantages, helping to comprehensively improve the performance of energy storage cabinets.

First, the temperature control accuracy is high. The temperature difference of the entire cabinet battery cells is strictly controlled within ±3℃, avoiding the imbalance of battery cell performance attenuation caused by uneven temperature, and effectively extending the overall service life of the energy storage system to more than 10 years. Second, the energy efficiency advantage is significant. Compared with traditional air-cooled technology, the energy consumption of the liquid-cooled system is reduced by 60%, and the comprehensive efficiency of the energy storage system is increased to more than 93.5%, helping users reduce operational costs. Third, the scenario adaptability is strong. It can adapt to the wide temperature range of -20℃~55℃, and is suitable for multi-scenario deployment of energy storage cabinets. Fourth, it is intelligent and convenient. The AI temperature control algorithm realizes automatic temperature control, combined with the cloud monitoring system, which can real-time monitor the operation status of the liquid-cooled system and support remote operation and maintenance, reducing manual maintenance costs.
