Range anxiety
Summary
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 is now primarily used in reference to the practical driving range of battery electric vehicles (BEVs), is 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.

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. , Estonia is 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 , and a higher density in urban areas. Estonia's land area and population density are likely factors that have made this viable.
