"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."

“电池的特性对于锂电池化学物质的发展以及在日常设备中安全有效地应用至关重要。考虑到它们在电动汽车中的使用，这一点尤为重要，因为在电动汽车中，测试期间获得的数据的准确性会显著影响模块和相关热管理系统的设计，并极大地影响性能。因此，了解特定的电池化学成分和结构是否能够在正常和极端使用条件下以安全的方式提供足够的电力是至关重要的。防止电池过热的冷却系统设计是每一辆电动汽车的必要要求，它对安全性、电池寿命、车辆续航里程和车辆性能都有影响。因此，从本质上讲，它可以成就或破坏一个特定的电动汽车设计。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 London）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是一种通过直接增加或减少热量来精确控制电池温度的平台。每个单元根据其几何形状和特定成分细分为区域矩阵，每个区域的温度都是独立控制的。此外，通过使用预测内部温度的模型，可以无创地将这些内部温度控制到指定的深度或层。该项目进展顺利，正按计划交付预期的原型机。ICP使循环测试、压力测试等期间获得的数据的准确性和质量得以提高，最终转化为电池性能、可靠性和安全性的显著提高。随着可用数据质量的提高，在整个行业中建立新标准的潜力确实存在。因此，提出了一项工作计划，帝国团队将重点放在制定此类协议上，克兰菲尔德大学的研究人员将加入该计划，他们将增强团队的能力，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将专注于将这些规定的方法集成到ICP系统中，同时也将平台从目前的原型配置转变为预商用系统。”
