Abstract

Electrification of drivetrain systems is now seen as a major opportunity by the transportation industry across the globe to reduce the greenhouse gas emissions and revolutionize the travel patterns of millions of people. The cumulative number of plug-in hybrid and battery electric vehicles (EVs) sold in the United States has now surpassed 2 million in 2021, according to the International Energy Agency. The introduction of EVs in different classes of passenger vehicles and the continued drop in prices spurred by government incentives have attracted the attention of consumers despite certain barriers, such as higher initial cost and range anxiety. In the United States, the EV market share is now growing at an exponential pace, with the domestic automakers allocating a lion’s share of new and future car sales to EVs. Additionally, different market studies project decreasing cost and rising sales of medium- and heavy-duty electric trucks. Although electrification initiatives are strongly pursued in the on-road passenger vehicle market, off-highway sectors, such as construction, mining, and agriculture, are also gradually implementing electric drivetrain technologies in their machineries. As EVs grow in popularity on a global scale, innovative drivetrain technologies must meet the increasing energy demand by significantly increasing system efficiency.

用于非公路重载应用的碳化硅逆变器:电力电子封装中热学和热机械设计的重要性
动力传动系统的电气化现在被全球交通运输业视为减少温室气体排放和彻底改变数百万人出行模式的重大机遇。根据国际能源署的数据,到2021年,在美国销售的插电式混合动力汽车和纯电动汽车(ev)的累计数量已超过200万辆。尽管存在一些障碍,如初始成本较高和里程焦虑,但电动汽车在不同级别乘用车中的引入以及政府激励措施推动的价格持续下降,吸引了消费者的注意。在美国,电动汽车的市场份额正以指数级的速度增长,国内汽车制造商将新车和未来汽车销售的大部分份额分配给了电动汽车。此外,不同的市场研究预测中、重型电动卡车的成本下降和销量上升。尽管在公路乘用车市场大力推行电气化举措,但非公路部门,如建筑、采矿和农业,也在逐步在其机械中实施电动传动系统技术。随着电动汽车在全球范围内的普及,创新的动力传动系统技术必须通过大幅提高系统效率来满足日益增长的能源需求。

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.
