The number of EV charging stations across America is increasing, thus paving the way for wider adoption of electric vehicles. But a lot of the infrastructure surrounding charging has remained complicated and time-consuming. Charging points typically require downloading an individual app -- or in some cases, making a phone call to a customer rep -- before you can start juicing up. It's a faff. Now, though, Electrify America is working on a program that will let you pay for electric vehicle charging simply by plugging in your vehicle.
