Novel self-regulating CHIP (Cooling and Heating Integrated Pipe) thermal management systems for EV batteries

“这是一个为期12个月的可行性项目，有3个合作伙伴，热跟踪有限公司（主要合作伙伴和中小企业），诺贝尔汽车零部件英国有限公司（一级供应商和一家大公司）和沃里克制造集团（RTO）我们的愿景是转移热跟踪的铝基聚合物智能自调节技术到电池热管理系统。自调节加热器不会烧坏，从而消除了热失控。关键目标是1）加热原型的开发2）冷却模块的结合3）组合加热/冷却模块的开发4）电气和流体连接器的开发5）热建模6）放大评估我们的方法有两个步骤。在步骤1中，我们用自调节聚合物加热器替换了最先进的EV电池加热器。我们估计，其好处包括更好的安全性，降低成本和减轻电池的重量。第二步是用CHIP（冷却和加热集成管）取代最先进的EV冷却模块。CHIP模块可以作为冷却模块或加热模块操作。我们已经估计了这些好处，并将其与8个法拉第目标进行了比较。我们的分析表明，CHIP技术将在8个法拉第靶中的7个中具有显著的优势，此外还将显着减轻EV电池的重量。创新功能包括：1）CHIP模块可以作为加热模块或冷却模块操作2）自调节聚合物将最大限度地减少表面温度的变化3）铝导体实现灵活的几何形状，因此，加热器可以定制成任何形状、任何电池类型或模块/组件配置。"

"This is a 12-month feasibility project with 3 partners, Heat Trace Ltd (Lead Partner and SME), Nobel Autoparts UK Ltd (Tier 1 supplier and a Large company) and Warwick Manufacturing Group (RTO)Our vision is the transfer Heat Trace's aluminium-based polymeric smart self-regulating technology into Battery Thermal Management systems. Self-regulating heaters cannot burn out which eliminates thermal runaways.The key objectives are the1) Development of heating prototypes2) Incorporation of cooling modules3) Development of a combined heating/cooling module4) Development of electrical and fluid connectors5) Thermal modelling6) Evaluation of scale upOur approach has 2 steps. In step 1 we replace a state-of-the art EV battery heater with a self-regulating polymer heater. We have estimated that the benefits include better safety, reduced costs and reduced weight of the battery.Step 2 is to replace the state-of-the-art EV cooling module with a CHIP (Cooling and Heating Integrated Pipe). A CHIP module can be either operated as a cooling module or a heating module. We have estimated the benefits and compared them to the 8 Faraday targets. Our analysis shows that the CHIP technology will have significant benefits in 7 of the 8 Faraday targets and in addition will show significant weight reduction of the EV battery.The innovate features include1) The CHIP module can be operated either as a heating module or a cooling module2) The self-regulating polymer will minimise variation of surface temperature3) The aluminium conductors enable flexible geometry, so heater can be customised to any shape, any cell type or module/pack configuration."
