range anxiety 里程焦虑

Range anxiety is the fear that a vehicle has insufficient¹ range to reach its destination and would thus strand² the vehicle's occupants. The term, which is primarily used in reference to battery electric vehicles (BEVs), is considered to be one of the major barriers to large scale adoption³ of all-electric cars. The term range anxiety was first reported in the press on September 1, 1997 in the San Diego Business Journal by Richard Acello referring to worries of GM EV1 electric car drivers. On July 6, 2010, General Motors filed to trademark⁴ the term.

“里程焦虑”是对于汽车续航不足以到达目的地、和因此导致的车内乘客被滞留的担忧。这个词主要用在电动汽车领域，“里程焦虑”也被认为是纯电动汽车被广泛接受面临的主要障碍之一。1997年9月1日，《圣地亚哥商业周刊》在报道美国通用汽车EV1电动车司机的焦虑时首次使用了“里程焦虑”这个词。2010年7月6日，通用申请将这个词注册为商标。

 

The main strategies to alleviate⁵ range anxiety among electric car drivers are the deployment⁶ of extensive charging infrastructure⁷, the development of higher battery capacity at a cost-effective price, battery swapping⁸ technology, use of range extenders, accurate navigation and range prediction for long trips.
