ACE Battery Liquid Cooling Module: High Energy, Safe, Intelligent, and Efficient

In today’s rapidly evolving global energy landscape, energy storage is shifting from a technology once regarded as optional to an indispensable foundation for modern power systems. ACE is introducing a new generation of battery modules designed for 1500 V high-voltage energy storage systems. Featuring high energy density, uncompromising safety, advanced thermal management, and streamlined operation and maintenance, these modules are engineered to meet the demanding requirements of industrial and commercial applications, power generation, grid-scale services, and behind-the-meter use cases.

Highly Integrated Design: More Space-Saving, More Efficient

Each module is built around a high-capacity lithium iron phosphate (LFP) cell with a capacity of 314 Ah, optimized for long-duration energy storage.  With industry-leading energy density and exceptional cycle life, it significantly reduces the levelized cost of storage (LCOS) over the system’s lifetime.

Building on this foundation, the system adopts an innovative large-module architecture that boosts integration, reduces unnecessary structural components, and maximizes volumetric efficiency. The module employs a lightweight band-clamped modular frame to further reduce weight while maintaining mechanical robustness. This enhances ease of transportation, installation, and future expansion—making it ideal for applications where space and weight are critical factors.

Layered Safety Protection: From Insulation to Thermal Runaway Prevention

Safety remains the top priority in any energy storage system. The module has successfully passed a stringent 4380 V DC dielectric withstand test, demonstrating superior insulation performance with no observed insulation breakdown or electrical failure. It has also completed UL 9540A thermal runaway propagation testing, effectively suppressing thermal propagation under extreme conditions and ensuring product reliability.

In addition, multiple hardware-level disconnection mechanisms—such as fuses and manual service disconnects (MSDs)—are seamlessly integrated with the Battery Management System (BMS). This creates a closed-loop safety process, from millisecond-level fault detection to rapid automatic disconnection.

Intelligent Liquid-Cooling System: ≤3°C Temperature Difference for Longer Life and Greater Stability

The module incorporates advanced liquid-cooling technology paired with intelligent thermal-control algorithms to manage precise heating and cooling across each unit. The internal temperature difference is controlled within 3°C, greatly improving cell consistency, usable capacity, and overall service life.

Compared to traditional air-cooling solutions, liquid cooling operates more quietly, consumes less energy, and is less affected by dust or environmental conditions—ensuring adaptability across a wide range of climates and applications.

Modular, Fast-Maintenance Design: Plug-and-Play, Zero Hassle

Operational efficiency is further enhanced by a highly modular internal structure that minimizes the number of components. The MSD and BMU support plug-and-play replacement without the need for special tools or complex disassembly, significantly reducing system downtime and lowering maintenance costs. Standardized interfaces and an intuitive layout make field servicing faster, safer, and more reliable.

All-Scenario Adaptability, Empowering a Greener Future

Looking ahead, ACE Battery’s liquid cooling energy storage modules will continue to drive global green-energy transformation through high integration, outstanding safety, exceptional reliability, and robust flexibility—making every kilowatt-hour more efficient, safer, and more sustainable.
