"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."

“这是一个为期 12 个月的可行性项目，共有 3 个合作伙伴：Heat Trace Ltd（主要合作伙伴和中小企业）、Nobel Autoparts UK Ltd（一级供应商和一家大型公司）和 Warwick Manufacturing Group (RTO)。我们的愿景是将 Heat Trace 的铝基聚合物智能自调节技术融入电池热管理系统，自调节加热器不会烧坏，从而消除了热失控。主要目标是 1) 开发加热原型 2) 纳入冷却模块 3) 开发组合加热/冷却模块 4) 开发电气和流体连接器 5) 热建模 6) 放大评估 我们的方法有 2 个步骤 在步骤 1 中，我们用自热式电动汽车电池加热器取代了最先进的电动汽车电池加热器。我们估计其好处包括更好的安全性、降低成本和减轻电池重量。第二步是用 CHIP（冷却和加热集成管道）取代最先进的 EV 冷却模块。芯片模块可以作为冷却模块或加热模块运行。我们估算了收益并将其与 8 个法拉第目标进行了比较。我们的分析表明，CHIP 技术将对 8 个法拉第目标中的 7 个具有显着优势，此外还将显着减轻电动汽车电池的重量。创新功能包括 1) CHIP 模块可以作为加热模块或冷却模块运行模块2) 自调节聚合物将最大限度地减少表面温度的变化3) 铝导体可实现灵活的几何形状，因此加热器可以定制为任何形状、任何电池类型或模块/电池组配置。”
