Introduction: The Critical Impact of Temperature-Control Technology on Energy Storage Benefits

Against the backdrop of large-scale development of energy storage in the industrial and commercial sectors, the thermal management system, as a core component, directly affects the efficiency, lifespan, safety, and overall economic viability of energy storage systems. The revenue generated from the price difference between peak and off-peak electricity tariffs is currently one of the primary sources of profit for energy storage power stations; and whether the thermal management system can precisely match cooling demands and minimize energy losses has become a key factor determining the upper limit of these power stations’ profitability.

SAV’s “Wind-Liquid Dual-Drive Intelligent Cooling”: From Collaboration to Upgrade

The “Wind-Liquid Dual-Engine Intelligent Cooling” technology, innovatively developed by SAV, does not simply combine the functions of air cooling and liquid cooling; rather, it achieves a comprehensive upgrade of both technologies through intelligent synergy. By deeply integrating the advantages of air cooling and liquid cooling, this technology flexibly switches among three modes—air cooling, wind-liquid hybrid, and liquid cooling—depending on different temperatures and application scenarios. This fundamentally overcomes the limitations of single cooling methods, making the temperature-control system a key enabler for enhancing energy conversion efficiency.

Reduce auxiliary power consumption and improve conversion efficiency.

Traditional single-temperature-control modes often lead to energy waste because they cannot be adjusted on demand. The “Wind-Liquid Dual-Drive Intelligent Cooling” system, powered by SAV’s self-developed EMS—SAV E-Bao—implements intelligent control, significantly reducing auxiliary power consumption. By continuously sensing the ambient environment and battery status in real time, it provides precise criteria for mode switching, enabling the “Wind-Liquid Dual-Drive Intelligent Cooling” technology to shift from “passive adaptation” to “proactive efficiency enhancement.”

Low-temperature mode: The system can operate efficiently solely by natural air cooling. This significantly reduces unnecessary energy consumption, with energy savings of up to 60% compared to conventional liquid cooling.

Hybrid Mode: At moderate temperatures, the system switches to a combined “natural air cooling + liquid cooling” approach. While maintaining excellent cooling performance, this hybrid solution reduces auxiliary power consumption compared to conventional approaches, boosting overall energy efficiency by more than 30%.

High-temperature mode: Comprehensive liquid cooling with rapid circulation of low-temperature coolant ensures that the temperature difference among battery cells is kept within ±2℃, meeting the system’s high-power thermal management requirements and guaranteeing that the battery operates within an efficient and safe range.

It operates stably in low-temperature environments, strikes a balance between efficiency and energy consumption under normal operating conditions, and efficiently meets thermal management safety requirements under high-temperature conditions—ensuring that the system maintains high efficiency across various scenarios. This “on-demand regulation” wind-liquid dual-engine intelligent cooling system significantly boosts the energy conversion efficiency of energy storage, directly enhancing the profitability of energy storage systems.

High efficiency equals high returns—accelerating project investment payback.
The “Wind-Liquid Dual-Drive Intelligent Cooling” technology achieves an energy conversion efficiency of up to 92.9% (@0.25C). On the one hand, this ensures that the energy storage system maintains high efficiency over the long term; on the other hand, it effectively extends the cycle life of the battery system, meaning that large-scale battery and refrigerant replacements will not be required for 10 years, thereby enhancing asset stability.

More critically, by dynamically matching cooling demands, we can avoid the energy waste caused by the “over-temperature control” typical of single liquid-cooling systems, significantly reducing the levelized cost of electricity (LCOE) for power stations and increasing annual revenue by approximately RMB 100,000 per 1 MWh. The direct benefits from higher efficiency shorten the investment payback period, fully demonstrating the core value of the energy storage market—“efficiency is paramount.”

Ultra-high cost-effectiveness across all scenarios, unlocking efficiency potential.

The “Wind-Liquid Dual-Drive Intelligent Cooling” mode boasts exceptional cost-effectiveness. It not only covers a wide range of global climate conditions—whether it’s the hot, dry desert regions, the humid and rainy coastal areas, or the frigid high-latitude regions—but also ensures stable operation in all of them. Moreover, this mode enables precise control over various industrial and commercial energy-storage applications—from large-scale energy-storage power stations in industrial parks to distributed commercial energy-storage systems—fully meeting cooling demands across different regions and scenarios, thereby providing reliable assurance for the efficient and safe operation of energy-storage equipment.

From technological innovation to reshaping industry value

At a critical juncture when the energy storage industry is shifting from “scale expansion” to “quality-driven competition,” SAV’s “Wind-Liquid Dual-Drive Intelligent Cooling” technology directly boosts revenue growth by enhancing efficiency, providing industrial and commercial energy storage power stations with quantifiable value-added benefits. The implementation of this technology marks a new stage in energy storage thermal management—moving from merely “meeting functional requirements” to “adding value through enhanced performance”—and injects strong momentum into the industry’s high-quality development.
