Though most drivers agree that they should pay something to charge their EVs at private business locations, according to the Christian Science Monitor, many charging stations are currently charging $2 per hour, which users see as an unfair rate. Most mass-market plug-in electric vehicles use about 3.3 kw per hour - which costs an average of about 50 cents per hour. Newer models can charge even more efficiently.
Most states do not allow individual vendors to set usage rates on their own (they are set by state-regulated utilities). But California has passed a law allowing owners of charging stations to decide how they want to charge: per hour or per kilowatt-hour; other states are expected to follow suit.
Two executives at Coulomb Technologies, who are responsible for the installation of the ChargePoint network of charging stations, have argued that EV owners should use their market force and avoid using stations that charge more than $1 per hour unless absolutely necessary.
Many business may still keep their charging stations free, as an incentive for EV owners to frequent their businesses. Many government or office locations may also make public charging available as an incentive for EV adoption. But as an industry standard develops around a fair rate for EV charging, users have an important role to play in expressing what they consider to be a fair price.
Readers, what do you think would be a fair rate to pay to charge your electric vehicle?
