Customer Rewards Charging
I believe that EV charging will be free, fast and ubiquitous. Here's how.
Shopping mall charging plus 200+ range vehicles can solve the problem of getting a charge. Three things are needed: parking space, charging equipment, and power. The crucial question is who pays for what. With the typical Supercharger set up Tesla bears the greatest financial responsibility. They pay the full cost of equipment and power, even if they are leasing space at below market prices. They are able to get favorable leasing terms bcause they parking lot owner believes that increased foot traffic and visability will enhance sales at nearby stores and restaurants. With destination charging, Tesla pays for the equipment and the land owner provides space, installation and power. Again the land owner is willing to do this because they believe it is in their economic interest to attract patrons. In many cases, the relative slowness of a HPWC compared to a SC works to the advantage of the participating land owner. They desire the patron to remain for a long charge, several hours, and do not want to pay for too much power. In all these situations there is a combination of marketing benefit and cost controls. Businesses will participate when they perceive that there are adequate controls are in place to assure that marketing cost/benefit tradeoff is favorable.
Consider that my local supermarket, Kroger, has a customer loyalty program called KrogerPlus. When my family shops at Kroger, we earn reward points that are redeemable as discounts on gasoline. Depending on how much we shop week can get a discount from $0.05 to $0.70 per gallon. So for a week's worth of shopping I might typically get a reward of $0.20/gallon on 15 gallons, a benefit of about $3 for say $200 worth of grocery sales. This is about a 1.5% reward which is substanial for a low margin business like groceries. Kroger is willing to subsize my weekly gas bill because they believe it motivaes sales and loyalty and because they've got tight controls in place, the KrogerPlus card, to assure that the reward and sales are linked and in balance. Suppose for sake of arguement Kroger thought they could achieve the same marketing outcomes without the overhead of the KrogerPlus card. That is, suppose they just gave everyone a low price on gas under the hopes that customers would stick around and buy their groceries from Kroger. It that situation, Kroger is potentially subsizing lots of gas for customers who never buy anything else from the supermarket. Without direct linkage they simply cannot afford to offer much of a fuel subsidy. Maybe they could offer fuel at cost, but not much lower. So it is that customer reward programs provide the direct linkage and program controls that assure a business will get a favorable return on their marketing dollar.
The logical next step in the evolution of charging infrastructure is to support customer reward programs with all the controls that marketers require. Tesla or a third party could operate a custmer rewards program that businesses as different as supermarket and credit card issuer could participate in. Imagine as a consumer, you have an app on your phone or car that links up with all your customer rewards programs that participate in the charging rewards program. So you've got some reward points from your grocery market, pharmacy, online retailer, credit card, hotel chain, etc. You pull up to a RewardsCharger at a convenient location. The app allows you to access the charger for free. You redeem reward charge points for each kWh or minute of charge. While you charge, the app tells you which loyalty program is providing you with power, how much. The program is also able to reinforce their marketing return by sending you messages, video and audio while you charge. Yes, there is even an opportunity to pay for your free charge by simply being exposed ads. So while I am redeeming my KrogerPlus point, Kroger gets to tell me about wonderful things they have in store for me or they could simply thank me for being a valued KrogerPlus customer and wish me a nice day. Most consumers don't really like being bombarded with advertising media, but it pays the bills. This is what makes TV, radio, and many online services free to access. Loyalty programs are more compelling than simply selling ad space because there is much stronger customer engagement. The reward charging program would harness marketing dollars from a wide slectrum of businesses to provide free, fast charging everywhere. It basically answers the question of who pays and assures marketing controls such that participants can get a positive marketing ROI while subsidizing charging for everyone, everywhere.
Relative to gasoline, I think that electricity is cheap enough that customer loyalty programs should suffice to cover the full cost. This is important to consider in light of recent downturn in gas prices. One thing that's always better than cheap gas is free, fast charging.
My belief is that this sort of rewards charging program is inevitable. A company like Google could make it happen in a heartbeat once they perceive the opportunity. And such a program would definitely accelerate the transition to sustainable transport regardless how cheap gas might become. So it remains to be seen if Tesla will want to lead in this direction or wait for Google or someone else to beat them to it and define the parameters of the program.
