Developing the Isothermal Control Platform (ICP) as the Basis of New Proposed Standards for the Testing of Lithium Batteries for Use in Electric Vehicles.

“电池的特性对于锂电池化学的开发及其在日常设备中的安全有效实施至关重要。当考虑它们在电动汽车中的使用时，这一点特别重要，因为测试期间获得的数据的准确性会显著影响模块的设计，相关的热管理系统，并极大地影响性能。因此，理解特定的电池化学物质和构造是否能够以安全的方式提供足够的电力以在正常和极端使用条件下驱动车辆是至关重要的。防止电池过热的冷却系统的设计是每辆电动汽车的必要要求，并影响安全性，电池寿命，车辆范围和车辆性能。为了解决这些问题，在过去的八个月里，热危害技术（THT）和伦敦帝国理工学院（Imperial College（帝国）参与了等温控制平台（ICP）的开发，作为法拉第挑战赛资助的可行性研究的一部分。ICP是一个平台，通过添加或直接除去热量。每个单元根据其几何形状和特定组件被细分为区域矩阵，并且每个区域的温度都被独立控制。此外，通过使用预测内部温度的模型，可以非侵入性地将这些设备的内部温度控制在特定的深度或层。ICP使循环测试、压力测试等过程中获得的数据的准确性和质量得到改善，最终转化为电池性能、可靠性和安全性的显著提高。随着数据质量的提高，存在着为整个行业制定新标准的真实的潜力。因此，提出了一项工作计划，帝国团队专注于开发此类协议，并由来自克兰菲尔德的研究人员加入，他们将提高团队的能力，并为将这些测试建立为国际公认的标准提供额外的动力。在项目的研究阶段，THT将集中精力将这些规定的方法集成到ICP系统中，同时将平台从当前的原型配置转变为预商用系统。"

"The characterisation of batteries is critical in the development of lithium battery chemistries and in their safe and efficient implementation in every-day devices. This is of particular importance when considering their use within electric vehicles, where the accuracy of data obtained during tests can significantly influence the designs of modules, the associated thermal management systems and greatly affect performance. Consequently, it is fundamental to understanding whether or not particular battery chemistries and constructions are capable of providing enough power in a safe manner to drive a vehicle under both normal and extreme conditions of use. The design of a cooling system which prevents batteries from overheating is a necessary requirement in every electric vehicle and impacts on safety, battery longevity, vehicle range and vehicle performance. So, in essence it can make or break a particular electric vehicle design.To address these issues, during the past eight months Thermal Hazard Technology (THT) and Imperial College London (Imperial) have been involved in the development of the Isothermal Control Platform (ICP), as part of a Feasibility Study funded by the Faraday Challenge.The ICP is a platform which controls the temperature of a battery precisely by adding or removing heat directly. Each cell is subdivided into a matrix of zones based on its geometry and specific components, and the temperatures of each of these zones is controlled independently. Furthermore, by using a model for predicting internal temperatures it is possible to control the internal temperature of these to a specified depth or layer non-invasively.The programme is progressing well and is on track to deliver the expected prototype. The improvements in the accuracy and quality of data obtained during cycling tests, stress tests, etc. which the ICP makes possible, are ultimately translated into significant gains in battery performance, reliability and safety. With such enhancements in the quality of data available there exists a real potential for setting new standards across the whole industry.A programme of work is therefore proposed whereby the Imperial team focuses on developing such protocols, and are joined by researchers from Cranfield who will enhance the team's capabilities and give additional momentum to establishing these tests as internationally recognised standards. During the Research phase of the project, THT will concentrate on integrating these prescribed methods into the ICP system, whilst also taking the platform from its current prototype configuration to a pre-commercial system."
