日常英語 range anxiety 里程焦慮

Range anxiety is the fear that a vehicle has insufficient range to reach its destination and would thus strand 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 adoption 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 trademark the term.

“里程焦慮”是對于汽車?yán)m(xù)航不足以到達目的地、和因此導(dǎo)致的車內(nèi)乘客被滯留的擔(dān)憂。這個詞主要用在電動汽車領(lǐng)域，“里程焦慮”也被認為是純電動汽車被廣泛接受面臨的主要障礙之一。1997年9月1日，《圣地亞哥商業(yè)周刊》在報道美國通用汽車EV1電動車司機的焦慮時首次使用了“里程焦慮”這個詞。2010年7月6日，通用申請將這個詞注冊為商標(biāo)。
