The global energy storage industry is rapidly advancing toward ultra-high capacity, high energy density, and long-cycle operational reliability. As large-scale utility and commercial & industrial (C&I) energy storage projects continue to scale up, 587Ah large-format prismatic lithium battery cells have emerged as the mainstream core component for next-generation Battery Energy Storage Systems (BESS). Compared with traditional low-capacity cells, 587Ah high-density cells deliver higher energy output and lower system integration costs, yet they generate significantly concentrated heat during high-rate charging and discharging cycles. Uncontrolled heat accumulation leads to uneven cell temperature distribution, accelerated capacity attenuation, shortened battery lifespan, and even potential thermal runaway risks, making precise, efficient, and stable thermal management a core prerequisite for safe and long-term ESS operation.
Tailored exclusively for 587Ah prismatic battery modules, the Trumony Aluminum 587 ESS Cooling Plate is a high-performance liquid cooling solution optimized for large-capacity energy storage scenarios. It addresses the core thermal pain points of high-density ESS, delivering uniform heat dissipation, minimal temperature difference, and stable thermal control throughout the battery pack lifecycle. By balancing the operating temperature of every single cell, the cooling plate effectively improves the overall consistency of the battery cluster, suppresses differential aging between cells, and comprehensively extends the service life of energy storage systems, laying a solid foundation for reliable, low-maintenance, and high-efficiency ESS operation.
Crafted from premium AL3003MOD high-performance aluminum alloy, the cooling plate achieves an optimal balance of ultra-high thermal conductivity, superior structural rigidity, and outstanding environmental adaptability. The specialized alloy material features excellent heat transfer efficiency, stable mechanical properties, and remarkable anti-corrosion capability, perfectly adapting to long-term uninterrupted operation in complex and harsh outdoor and containerized ESS environments. Adopting precision integral stamping and high-vacuum brazing integrated manufacturing technology, the product eliminates internal structural gaps, achieves seamless overall connection, and delivers exceptional structural integrity and zero-leakage performance. It can withstand long-term hydraulic impact and temperature cycling changes, avoiding liquid leakage, structural deformation or performance attenuation during high-load system operation, ensuring long-term stable and reliable operation.
We have structurally optimized the internal coolant flow channel through iterative fluid simulation and experimental verification, forming a scientific and efficient heat exchange architecture. This customized flow channel design enables full-coverage and uniform coolant circulation across the entire contact surface of 587Ah cells, realizing synchronous and efficient heat transfer with no thermal dead zones. Meanwhile, the low flow resistance structural design effectively reduces hydraulic loss and pump power consumption, improving the overall energy efficiency of the liquid cooling system and helping ESS achieve lower operational energy consumption and higher net power output.
