Range anxiety is the fear of driving an electric car and running out of power without being able to find a charging point on time to replenish the battery. Thus you fear being left stranded. You worry about where you can charge on long trips, how long charging takes, whether the charger will be available when you get there, whether the charger is working, whether it is producing enough kilowatts, and how much will it slow you down on these cross-country trips. Indeed, range anxiety is considered to be one of the major psychological barriers to large-scale public adoption of electric cars.
