Electrification’s Charging Challenge

Public chargers were installed in high-profile areas like shopping centers, parking garages, and at the workplace. For the longest time, it wasn’t unusual to see these chargers go unused for long periods of time. Green Car Journal editors experienced this first-hand for many years during our daily travels with plug-in test cars.

Often enough, ours was the only electric vehicle plugged in at a bank of four chargers at a local commercial center in our city. It was the same story in the parking garage downtown. But that’s changed, signifying both the positives and the challenges of a plug-in vehicle market that’s gathering momentum, and numbers. These days those chargers are often occupied when we pull up. Like most places, there simply don’t seem to be enough chargers to go around.

Many have heard about incidents at Tesla Supercharger sites, places where you can top off 80 percent of your battery charge in 30 minutes and then be on your way. The problem is, not everyone plugs in and then moves on. Superchargers, and chargers in general, are often located in areas where businesses are nearby so the experience is convenient and there’s something to do while charging. Tesla, in fact, has hinted that it’s taking this further and exploring Supercharger sites with food and amenities for those charging up their cars.

To be sure, not everyone stops for a 30 minute cup of coffee while charging. Shopping experiences in nearby stores can take much longer than that, and if all chargers are being used with others waiting to top off before continuing their journey, long waits are a problem. At times that leaves EV drivers frustrated with those who leave their car plugged in long after their needed charge is complete. The result? An interesting phenomenon in recent years called ‘charge rage.’

charging-at-two-chargersThis isn’t unique to Superchargers or to public charging sites. Workplaces can have similar experiences as employees in increasing numbers step up to battery electric and plug-in hybrids. They’re encouraged to do so not only to drive ‘greener,’ but also to benefit from shorter commutes in states that allow solo EV drivers in high occupancy vehicle (carpool) lanes. That privilege alone has spurred many commuters to go electric. Time isn’t just money. It’s also…time. Spending a half-hour less each way during the daily commute is worth more than money in many respects. And once the commute is done, it’s time to charge.

Most companies offering chargers have limited numbers and often site these in favorable parking areas close to the workplace, further encouraging employees to go electric. It’s good for a company’s image and it’s the right thing to do. That said, expecting employees to free up a charger after a few hours and move their car farther out in an expansive parking lot is asking a lot, human nature being what it is.

Those who plug in while attending a conference of expo aren’t likely to return after an hour or two to unplug and move to another less convenient parking spot. With a limited number of charging spots available, other EV drivers counting on a range-extending charge aren’t likely to be pleased if all charging spots are taken.

Yes, there’s change afoot. Charging companies, automakers, utilities, and both state and local governments are striving to install an exponentially larger number of public chargers to alleviate the problem and keep pace with the growing number of plug-in vehicles on the road. But it hasn’t been fast enough…certainly not at a pace that’s keeping up with the larger number of electric vehicles on the road today.

Drivers have long been promised perks like free public charging, access to carpool lanes with a single occupant in an electric vehicle, and favorable parking with charging available, all to encourage them to go step up to a battery electric or plug-in hybrid vehicle. While not disappearing, these perks are getting harder to realize. And that’s not a good thing for the electric vehicles and the industry as a whole.
