Electric cars run on battery, and these powered-cells have a specific life. Once the battery is low on power, the car owner would take the vehicle to recharge the battery at one of the electric car stations near him. Unlike gas stations, you will not find an electric station at every nook-and-corner. The reason is that although people are moving towards electric vehicles, still the percentage of people using the electric car are less. Since there are fewer electric vehicles on the roads, there are fewer electric stations to charge your vehicle.
You will have to find out about these stations, especially if you are traveling long-distance. Otherwise, you may risk getting stuck with low-power in your car and no charging station near sight. You can search for these car charging stations when you travel beforehand, so you know exactly where to take your vehicle for a recharge.
