What's the cost to charge an electric car at a public station, and why
Every so often an electric car owner discovers a public charging station costing $3 per hour to charge their car. Their reaction isn't always positive because of the fee paid per mile of range received by charging.
The public charging stations fall into three groups. The first group is the stations in one of the two electric car charge station networks in the U.S., the Blink Network run by ECOTality, and the ChargePoint network run by Coulomb Technologies. The second group are the other public charging stations that aren't in one of those networks. The last group are the stations, in California and elsewhere, left over from 10 or so years ago when electric cars were last manufactured by the automakers.
