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. Since lack of information can be a contributing factor, a good navigation system with knowledge of the battery capacity and remaining distance can minimize the fear. There is also the possibility to minimize the fear before buying a vehicle. The American Automobile Association (AAA) has started a road-recharge pilot program in six cities: Knoxville, Los Angeles, Portland, San Francisco, Seattle and Tampa. EV-driving AAA members can use the truck's level 3 charging capacity to recharge a Nissan Leaf to 80% capacity in 30 minutes. Battery swapping Battery swapping is a strategy to avoid range anxiety that allows electric cars to extend their range through a battery switch station. At the station, the depleted battery is swapped for fully charged battery in about the same time that it takes to fill up a car with gasoline. Battery swapping is common in warehouses using electric forklift trucks. As the electric car emerged as the main competing technology in the late 1890s until the 1920s, the concept of exchangeable battery service was first proposed as early as 1896 in order to overcome the limited operating range of electric cars and trucks. The concept was first put into practice by Hartford Electric Light Company through the GeVeCo battery service and initially available for electric trucks. The vehicle owner purchased the vehicle from General Vehicle Company (GVC, a subsidiary of the General Electric Company) without a battery and the electricity was purchased from Hartford Electric through an exchangeable battery. The owner paid a variable per-mile charge and a monthly service fee to cover maintenance and storage of the truck. Both vehicles and batteries were modified to facilitate a fast battery exchange. The service was provided between 1910 and 1924 and during that period covered more than 6 million miles. Beginning in 1917 a similar successful service was operated in Chicago for owners of Milburn Light Electric cars who also could buy the vehicle without the batteries. Better Place The Better Place network was the first modern commercial deployment of the battery switching model.
