Advanced Water-Cooling Units for Next-Generation Battery Thermal Management Systems

In the rapidly evolving landscape of new energy vehicles (NEVs) and energy storage, maintaining optimal battery temperature is paramount for safety, performance, and longevity. NEWBASE, at the forefront of thermal management innovation, is proud to introduce its comprehensive series of intelligent water-cooling units, engineered to be the reliable core of your Battery Thermal Management System (BTMS).

A battery's efficiency, charging speed, and cycle life are intrinsically linked to its operating temperature. Industry consensus, supported by research from sources like the Society of Automotive Engineers (SAE), indicates that the ideal window for most lithium-ion batteries is between 15°C and 35°C. Operating outside this range can lead to reduced capacity, accelerated degradation, or in extreme cases, thermal runaway. NEWBASE's BTMS water-cooling units are precisely designed to maintain this critical temperature window, ensuring batteries operate at their peak potential in any condition.

At the core of our BTMS lies the high-efficiency liquid-cooling plate. NEWBASE utilizes premium materials to maximize performance. We employ specialized aluminum alloys, such as the 3003+4045 brazing composite plate. This combination leverages the excellent formability and corrosion resistance of 3003 aluminum-manganese alloy with the superior thermal conductivity of 4045 aluminum-silicon alloy. With a thermal conductivity (150-250 W/m·K) vastly superior to alternatives like stainless steel (~15 W/m·K), our design ensures rapid heat transfer from battery cells to the coolant, enabling faster and more uniform temperature regulation. Furthermore, the lightweight nature of aluminum (density ~2.7 g/cm³) contributes to overall vehicle weight reduction, directly enhancing the energy density and range of the electric system.

Understanding that one size does not fit all, NEWBASE offers a scalable range of water-cooling units from 5KW to 16KW cooling capacity. This allows for precise matching to system requirements, whether for:

• New Energy Commercial Vehicles:​ Buses, trucks, heavy-duty electric trucks, and construction machinery.

• Energy Storage Power Stations (ESS):​ Ensuring stability and longevity for large-scale battery storage systems.

Our units are configurable for complex thermal management scenarios, including combined battery and cabin cooling, integration with motor cooling circuits, and systems with heat recovery functionality. Standard intelligent features across the series include:

• Integrated PTC Liquid Heaters​ (Optional): For efficient battery heating in low-temperature environments.

• CAN 2.0 Communication:​ Seamless integration with vehicle or system BMS.

• Fault Self-Diagnosis & Real-time Data Upload:​ Enables predictive maintenance and remote monitoring.

• Multiple Operating Modes:​ Standby, cooling, heating, and self-circulation.

• Compliance with Class III EMC Requirements:​ Ensuring reliable operation in electrically noisy environments.

The journey from simple radiators to today's intelligent thermal management systems reflects decades of innovation. NEWBASE's water-cooling units embody this progress. By integrating advanced components like compressors, evaporators, condensers, and plate heat exchangers, our systems intelligently regulate coolant temperature and flow. This evolution is driven by the dual engines of technological advancement and stringent global energy-saving and environmental protection standards.

NEWBASE's water-cooling units represent more than just a component; they are a commitment to the safety, efficiency, and durability of your new energy applications. By ensuring that batteries, motors, and electronic controls operate within their optimal thermal range, we help our clients deliver products with greater range, longer lifespan, and ultimate reliability.
