Abstract

Technology for the electrification of transport is currently undergoing rapid development that is necessary for reducing greenhouse gas (GHG) emissions. On a global level, the transport sector is responsible for around 12% of the world’s GHG emissions. While the introduction of battery-electric cars is leading the way in terms of commercial scale, developments are also progressing toward electrification of heavy-duty vehicles for road freight transport and coastal transport by battery-electric ships. The performance of modern Li-ion batteries is also enabling electrification of other types of machines and small vehicles that have traditionally been powered by internal combustion engines (ICEs). However, until recently, the developments toward electrification have been mainly directed toward applications with either a large market for series-produced vehicles, such as electric cars, or a high degree of individual engineering for each unit, such as battery-electric ships. Still, there are several application areas where other types of vehicles and machines contribute significantly to GHG emissions.

挖掘机电气化:电气配置，碳足迹和改造解决方案的成本评估

交通电气化技术目前正在快速发展，这是减少温室气体排放所必需的。在全球范围内，交通运输部门的温室气体排放量约占世界温室气体排放量的12%。虽然电池电动汽车的引入在商业规模上处于领先地位，但用于公路货运和沿海运输的重型车辆的电气化也在取得进展。现代锂离子电池的性能也使传统上由内燃机(ice)驱动的其他类型的机器和小型车辆实现了电气化。然而，直到最近，电气化的发展主要是针对大批量生产的汽车(如电动汽车)或每个单元的高度个性化工程(如电池电动船)的应用。尽管如此，在一些应用领域，其他类型的车辆和机器对温室气体排放的贡献很大。

期刊介绍： IEEE Electrification Magazine is dedicated to disseminating information on all matters related to microgrids onboard electric vehicles, ships, trains, planes, and off-grid applications. Microgrids refer to an electric network in a car, a ship, a plane or an electric train, which has a limited number of sources and multiple loads. Off-grid applications include small scale electricity supply in areas away from high voltage power networks. Feature articles focus on advanced concepts, technologies, and practices associated with all aspects of electrification in the transportation and off-grid sectors from a technical perspective in synergy with nontechnical areas such as business, environmental, and social concerns.
