The Voltt: A Database of Battery Parameters for Virtual Modelling and Optimisation of Battery Cells to Accelerate R&D

随着汽车行业的快速电气化，全球原始设备制造商正在加快他们的计划和努力，以开发新的电池技术。各国政府的目标是最早在2030年禁止销售新的内燃机，需要提高电池性能和寿命以加快这一过渡。由于依赖物理测试和原型制作，电池开发昂贵、耗时和碳密集型。对高质量数据、昂贵设备和专业知识的要求，对该行业的新进入者构成了巨大的障碍。电池选择、系统设计和老化测试等活动需要数月甚至数年的时间来建立良好的接地和对有问题的电池的理解。可以使用建模和虚拟迭代来加速这种电池的开发。然而，尽管目前的电池软件平台提供了建模解决方案，但它们没有提供对电池潜在物理属性的洞察。这种洞察力，加上高精度的测试，是将尖端电池和下一代电池的新创新推向市场所必需的。关于：Energy已经将Faraday Institution研究项目中开发的研究商业化，这些研究项目旨在表征电池的电、电化学和热性能。该项目将与伦敦帝国理工学院合作开发先进的电池老化测试程序和型号，旨在降低到货商用车队的总拥有成本。集中化的定制测试方法减少了阻碍模型采用的障碍。“The Voltt”是为了加快电池开发，同时基于能量、功率和寿命进行设计优化而发明的。Voltt将提供可在现有建模软件中使用的特定电池数据集和模型的访问权限，从而简化从设计阶段到寿命结束的电池性能增强过程。

Alongside the rapid electrification of the automotive industry, global OEMs are accelerating their plans and efforts to develop new battery technologies. Governments aim to ban the sale of new internal combustion engines as soon as 2030, battery performance and lifetime need to be improved to accelerate this transition. Battery development is expensive, time-consuming and carbon-intensive due to the reliance on physical testing and prototyping. The requirements for high-quality data, expensive equipment and expertise pose a significant barrier for new entrants into the industry. Activities such as cell selection, system design and ageing tests require many months or even years to build a good grounding and understanding of the batteries in question. Modelling and virtual iteration can be used to speed up this battery development. However, while current battery software platforms offer modelling solutions, they do not provide insight on the underlying physical properties of batteries. This insight, together with high-precision testing is needed to bring new innovations to market for state-of-the-art and next-generation batteries. About:Energy has commercialized research developed within Faraday Institution research projects to characterise the electrical, electrochemical and thermal properties of a battery. This project will develop advanced battery ageing testing procedures and models with Imperial College London, aiming to reduce the total cost of ownership of Arrival’s commercial vehicle fleet. Centralising bespoke testing methods reduces the barriers that hinder the adoption of models. “The Voltt” is being created to speed-up battery development, while enabling design optimisation based on energy, power, and lifetime. The Voltt will offer access to specific battery datasets and models that can be used in existing modelling software, streamlining the enhancement of battery performance from the design stages to end-of-life.
