Range anxiety
Range anxiety is the driver's fear that a vehicle has insufficient energy storage (fuel and/or battery capacity) to cover the road distance needed to reach its intended destination, and would thus strand the vehicle's occupants mid-way. The term, which as of 2010[update] was used primarily in reference to the practical driving range of battery electric vehicles (BEVs), was considered to be one of the major psychological barriers to large-scale public adoption of 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, stating it was for the purpose of "promoting public awareness of electric vehicle capabilities". The Norwegian equivalent rekkeviddeangst was assigned second place in a list of Norwegian "words of the year" for 2013 by the Norwegian Language Council.
The main strategies to alleviate range anxiety among electric car drivers are the deployment of extensive charging infrastructure, the development of higher battery capacity at a cost-effective price, battery swapping technology, use of range extenders, accurate navigation and range prediction and availability of free loan vehicles for long trips.
According to a study by the American Automobile Association, the cure to range anxiety is owning an electric vehicle.
The range anxiety will limit the ability of the all electric car to be used in certain specific applications, even if the battery costs come down. - Bill Reinert, National manager of advanced technology at Toyota’s U.S. arm, 2010
Range anxiety may be exaggerated, as recent studies have concluded that most daily trips can be accomplished within the range of an inexpensive electric vehicle.
The concern that users of all-electric vehicles may become stranded has led to public calls for extensive public charging networks. As of December 2013[update], Estonia was the only country that had deployed an EV charging network with nationwide coverage, with fast chargers available along highways at a maximum distance of between 40 and 60 km (25 and 37 mi), and a higher density in urban areas. Estonia's land area and population density are likely factors that have made this viable. Care should be taken in comparing with other countries, since it is smaller than many first level subnational divisions, it is half the size of West Bengal and three counties in the USA have a larger land area.
Electric vehicle manufacturers have sought to quell range anxiety concerns through increased battery capacities to extend the vehicle's range. REVA has a proprietary technology called "Revive", which is a battery reserve that can be released by electric vehicle users by texting or calling an operations center. Using a range extender solution, as implemented in the Chevrolet Volt or the BMW i3, the internal combustion engine switches on to recharge the battery before it is empty. Another method is the proposed Ridek modular vehicle approach whereby a vehicle's chassis could be exchanged for one containing a larger-capacity battery at a network of chassis-exchange stations before embarking on a long journey.
