In Europe, energy storage has evolved from an optional ancillary device into a core productive asset that underpins grid stability, ensures energy autonomy, and generates sustained revenue. Faced with high energy costs, complex grid requirements, and stringent sustainability goals, investors are shifting focus from upfront cost to full lifecycle performance: Can it maximize output within limited space? Can it remain healthy despite frequent and intensive use? Can it operate reliably across diverse and demanding environments? The Dunext liquid-cooled PowerHill (233kWh) energy storage system answers these questions with precision thermal management and the DuLink cloud platform, directly addressing Europe's needs for high-intensity cycling, high power density, and high environmental adaptability to deliver superior asset value.

Three Pillars of Asset Performance

The European market demands precision thermal management that goes beyond basic cooling, defined by three critical performance pillars:

• Longevity Under Intensive Cycling: Volatile energy prices require that systems must endure multiple deep charge-discharge cycles daily. This mandates exceptionally slow and predictable cell degradation; any abnormal capacity fade directly erodes financial returns.
• Value in Constrained Space: In Europe, where space is a scarce asset, high power density is essential to maximize both energy capacity and output per square meter, directly boosting return on spatial investment. The key to achieving this lies in thermal management: compact cell integration concentrates heat, and only efficient, uniform cooling can maintain the system’s full performance without compromise.
• Reliability in All Climates: From Nordic winters to Southern European summers, storage systems must operate stably across all climates and respond rapidly to grid ancillary service demands. Precise thermal control is the foundation of this all-climate reliability and revenue potential.

The PowerHill Solution: Hardware and Software Synergy for Precision Temperature Control

The Dunext liquid-cooled PowerHill integrates precision hardware with intelligent software into a unified thermal management system:

• Hardware Uniformity Control Safeguards Extended Durability: Utilizing a multi-channel flow path design and U-shaped loop, it enhances impinging jet heat transfer within cold plates, significantly optimizing cooling efficiency and ensuring a temperature differential between cells of ≤2.5°C. This extreme uniformity fundamentally eliminates the "bucket effect" within battery packs, allowing all cells to operate synergistically within the optimal temperature window, providing the core physical safeguard for ultra-long cycle life.
• All-Climate Active Adaptation Unleashes Maximum Asset Potential: Integrated high-power independent chillers actively and precisely maintain battery temperature within the 25-35°C optimal operating range. Regardless of external environmental fluctuations, the system guarantees constant-power charging and discharging across a 0-100% State of Charge (SOC) range, ensuring asset output capability and dispatch reliability while maximizing revenue potential in both energy and ancillary service markets.
• DuLink Intelligent Enablement Facilitates Proactive Thermal Optimization: The DuLink cloud platform, leveraging cell-level real-time monitoring and data analytics, upgrades thermal management from "passive response" to "active prediction + dynamic optimization." By tracking the temperature performance of each cell in real time, algorithmic models preemptively predict thermal trends and dynamically adjust cooling strategies, intervening before potential thermal risks materialize. This not only enhances system operational reliability but also, through refined temperature control, optimizes system efficiency and energy consumption while preserving lifespan, maximizing asset operational value.
• Built-in Safety Protects Long-Term Asset Value: The combination of extreme temperature uniformity and intelligent monitoring significantly reduces the risks of localized overheating and thermal runaway. Precision thermal management also lays the groundwork for active safety strategies like pack-level targeted fire suppression. Coupled with a long-life design featuring coolant that requires no replacement for 10 years, it comprehensively safeguards asset security while reducing long-term operational costs, thereby enhancing the asset's overall net value.

Securing Your Energy Asset’s Future

In the European market, choosing energy storage is a long-term asset investment. The Dunext liquid-cooled PowerHill transforms precision thermal management into clear asset advantages through its dual core technological pillars of "precision hardware control + intelligent software enablement": ensuring longevity, unlocking spatial value, and guaranteeing all-climate reliability. Looking forward, Dunext is committed to collaborating with European businesses to build a high-reliability and high-yield benchmark for energy storage assets that make the energy transition more secure and profitable.
