Electric car recharging fee activism suggested by Coulomb CEO and CTO
How much should it cost to charge an electric car? In most cases public electric car charging stations are free to use, allowing electric car owners to drive for free. However the charging station network operators are beginning to impose fees of $3 per hour or more, which many say is too-high of a fee, begging the question of what's the appropriate fee for electric car charging. To complicate the issue, the cost of electricity for electric car charging is minimal, leaving electric car owners facing a large cost disparity to charge their car between home charging and public charging.
Last winter we wrote about how electric cars are cheaper to operate than gasoline cars, and more recently we noted a cost calculator published by Via Motors showing that commercial fleet owners can save a bunch of money through buying electric, or plug-in hybrid, trucks versus gasoline or diesel powered trucks. How? It's because electricity is a far cheaper fuel than either gasoline or diesel. How? It comes down to calculating the benefit (miles driven) per dollar spent on electricity or gasoline or diesel. This is an "operational cost" line of reasoning, and does not consider the full total cost of ownership. In the case of leasing a plug-in hybrid from a company like Via Motors, the lease cost does a nice job of capturing the cost of ownership and, depending on the usage level, the fuel cost savings can be significant enough to pay for the lease cost.
These savings depend on one thing: Being able to recharge the vehicle using electricity purchased via the price we typically pay the utility company. The national average for electricity is around $0.11 per kilowatt-hour, but varies from locale to locale depending on local utility rates.
When charging your electric vehicle in public the cost can be quite a bit higher than the cost of electricity. When browsing around the charging stations around the U.S., using the ChargePoint application, we see rates vary quite a bit with costs reaching as high as $3.50 per hour. The electric cars on the market either charge at a 3.3 kilowatt or 6.6 kilowatt rates, meaning at the national average for electricity a car charging at 6.6 kilowatts is consuming $0.73, per hour, or so worth of electricity. On the other hand, the car charging at a 3.3 kilowatt rate is consuming half that much electricity, or about $0.36 per hour. These are the electricity rates paid by retail consumers, a charging station business may be paying lower (or higher) electricity rates. In most states charging station owners are not allowed, by law, to charge per kilowatt hour for electricity because that is a right reserved solely to utility companies. Obviously there are costs on top of the electricity, such as leasing the spot for the charging station, as well as paying for the charging station, which must be rolled into the fee required to use the charging station.
In a recent interview with the Christian Science Monitor, Coulomb's CEO Pat Romano acknowledged the rates being charged by some members of the ChargePoint network are excessive. He said that $2 per hour is expensive, but that the pricing will "settle in" as the market matures, as electric car owners become better educated, and charging station owners learn more about the business.
The article goes on to say both Romano and Richard Lowenthal, Coulomb's Founder and CTO, are "advocates of per-kilowatt-hour pricing" for electric car charging stations, and that only 20% of ChargePoint stations are charging fees today. The article notes that in one scenario, a business hosting a charging station, makes economic sense right now because it encourages shoppers to spend more time in the store hosting the charging station. The more time a shopper spends in the store, the more they're likely to spend, especially if they're feeling some responsibility over consuming electricity at that store.
The two then suggest a bit of market activism by electric car owners, which may sound a little curious coming from the executives of the company which runs the ChargePoint network. They suggested that electric car owners should avoid charging stations that require a fee of more than $1 per hour. We, as consumers, have an ability to force market demand to lower the fees imposed by charging station owners. How? Simply by collaborating to eschew charging stations that charge a high fee.
But, you may wonder, are Romano and Lowenthal thinking by making this suggestion? They are the CEO and CTO of the company that runs the ChargePoint network, don't they control the prices to access charging stations? Nope. Coulomb's ChargePoint network is a payment settlement network, and Coulomb does not own the charging stations in the ChargePoint network. Instead the charging stations are purchased by businesses who join the ChargePoint network, and use it for collecting payments. Each charging station owner sets the fee structure as they wish for their charging stations.
