Low Cost Flexible Battery Packs for Commercial Vehicles

为了实现英国2050年净零排放的目标，柴油卡车的销售将需要从2030年起逐步停止。因此，制造商和运营商正在开发电动和混合动力总成，最初是在现有的车辆架构上。然而，构建基于模块的电池组来适应现有的车辆结构空间效率低、重量大且成本高，这些限制阻碍了卡车和动力总成的发展。迄今为止的工作表明，圆柱形电池阵列(而不是更大的模块)显著提高了柴油车转换中可用空间的利用，优化了重量分配，降低了成本，并有可能使电池容量翻一番。因此，该项目的目标是评估新电池设计的可行性，使用圆柱形电池(而不是更大的模块)直接创建低成本的三维电池组，以最大化现有车辆外壳中的可用空间。为了测试这一概念的可行性，关键项目的输出将是一个原型三维电池组，代表可能用于货运车辆的典型250-450千瓦时电池组的一部分。

To meet the UK's 2050 net-zero emissions target, sales of diesel lorries will need to be phased out from 2030\. Manufacturers and operators are therefore developing electric and hybrid powertrains, initially on existing vehicle architectures. However, building a module-based battery pack to fit an existing vehicle structure is space-inefficient, heavy and expensive, and these limitations are holding back truck and powertrain development.Work to date has shown that arrays of cylindrical cells (rather than larger modules) significantly improves the use of available space in conversions of diesel vehicles, optimising weight distribution, reducing cost and potentially doubling the battery capacity.The objective of this project is therefore to assess the feasibility of a new battery design, using cylindrical cells (rather than larger modules) to directly create a low-cost 3-dimensional battery pack that maximises the available space in existing vehicle envelopes.To test the feasibility of the concept, the key project output will be a prototype 3-dimensional battery pack, representing a section of a typical 250-450kWh battery pack likely to be used in a freight vehicle.
