Advanced Battery Thermal Management Systems (BTMS) for Electric Vehicles (EVs)
In the dynamic landscape of electric mobility, the performance and safety of Electric Vehicles (EVs) are intrinsically linked to the efficiency of their Battery Thermal Management Systems (BTMS). At NEWBASE, we are dedicated to providing cutting-edge BTMS solutions that ensure optimal battery performance, longevity, and safety. Our systems are designed to meet the diverse needs of the automotive industry, offering a range of active and passive cooling technologies to maintain battery temperatures within the ideal operational range.
Parallel Air Cooling BTMS
Our parallel air cooling BTMS is designed to address the complex thermal challenges of battery packs. Through extensive research and numerical simulations using Computational Fluid Dynamics (CFD), we have developed nine distinct types of parallel air cooling systems, each optimized for specific applications and conditions. For instance, BTMS IX has demonstrated superior performance, reducing the maximum temperature and temperature difference by 4.3°C and 6.0°C, respectively, compared to the Z-type BTMS (BTMS I).
U-Type Air Cooling BTMS
Our U-type air cooling BTMS is engineered to enhance heat dissipation through optimized airflow. By fine-tuning the intake and exhaust angles, as well as the gaps between cells, we achieve optimal cooling efficiency. Under conditions of a 2.5° intake angle, 2.5° exhaust angle, and equal channel gaps, our BTMS delivers the best cooling performance, ensuring uniform temperature distribution across the battery pack.
Axial Air Forced Convection
In some applications, we enhance the thermal performance of our air cooling systems by incorporating heat sinks. While this adds approximately 39% to the weight of the battery, it significantly improves heat dissipation. For applications where weight is a critical factor, our direct and indirect liquid cooling solutions offer a more balanced approach, adding only 2.95% and 7.16% to the battery weight, respectively.
Liquid Cooling BTMS
For high-performance applications, our liquid cooling BTMS provides superior thermal management. With higher thermal conductivity and heat capacity compared to air, liquid cooling ensures a more uniform temperature distribution within the battery module, meeting the cooling demands of high-rate discharge and charging. Our liquid cooling strategies include both direct and indirect cooling methods.
Direct Liquid Cooling
Our direct liquid cooling, also known as liquid immersion cooling, is ideal for applications requiring high thermal efficiency and uniform temperature distribution. By immersing the battery module in a cooling medium, we directly absorb the heat generated by the battery, simplifying system design and reducing complexity. Our cooling media are selected for their excellent chemical and physical properties, ensuring electrical insulation, non-toxicity, and environmental safety.
Hybrid Cooling Solutions
For the most demanding applications, our hybrid BTMS combines the best of both active and passive cooling technologies. By integrating phase change materials (PCMs) with forced air or liquid cooling, we achieve a balance between efficiency and cost-effectiveness. This approach not only enhances performance but also adapts to a wide range of operational environments, ensuring optimal thermal conditions regardless of external conditions.
Safety and Environmental Standards
Safety is paramount in BTMS design. Our systems are designed to prevent thermal runaway and ensure the safe operation of high-capacity lithium-ion batteries. We adhere to stringent safety and environmental standards, using highly efficient electric compressors and environmentally friendly refrigerants. Our BTMS is also designed to be compatible with various vehicle designs, minimizing packaging constraints and ensuring design flexibility.
