Abstract

An Electric Road System (ERS)—comprising a network of overhead cables to charge Heavy Goods Vehicles (HGVs) via a pantograph pick-up—is a cost-competitive solution to rapidly decarbonise the UK road freight sector. A major benefit over conventional battery electric HGVs is the reduction in battery capacities needed to fulfil logistics needs. In this study, we develop a detailed vehicle simulation model and use it to calculate the battery capacity requirements of real UK logistics journeys against a range of ERS network sizes and on-route static charging options. The results show that, averaged over all static charging scenarios, ERS reduces battery sizes by 41 %, 62 %, and 75 % for the ‘Light’ (2,750 km), ‘Medium’ (5,500 km) and ‘Heavy’ (8,500 km) ERS scenarios. Of the static charging scenarios, drop-off charging is shown to be more effective than rest stop charging at reducing battery sizes.

电动道路系统或大电池:对英国公路货运的影响

电动道路系统(ERS)——由架空电缆网络组成，通过受电弓拾取器为重型货物车辆(hgv)充电——是一种具有成本竞争力的解决方案，可以迅速使英国公路货运部门脱碳。与传统电池电动hgv相比，一个主要优点是减少了满足物流需求所需的电池容量。在这项研究中，我们开发了一个详细的车辆模拟模型，并使用它来计算真实的英国物流旅程的电池容量需求，针对一系列ERS网络规模和路线上的静态充电选项。结果表明，在所有静态充电场景中，平均而言，在“轻型”(2750公里)、“中型”(5500公里)和“重型”(8500公里)的ERS场景中，ERS将电池尺寸减少了41%、62%和75%。在静态充电场景中，在减小电池尺寸方面，下降充电比静止充电更有效。
