Filling your car with gas is easy. You pull up to a pump, put the nozzle in the hole, and hit the button for the cheapest swill your car will accept. A few minutes later, it clicks, and you’re done. Charging electric devices is even simpler — we’ve all plugged in a phone, put a toothbrush on a stand, or popped a battery into a wall charger. So ?

It seems there are a few reasons: with finicky connections to the cars they’re serving, the struggles of — even EV owners who take up fast-charging spots with their slow-charging cars. The EV charging experience is bad, and it’s making electric car ownership (or the appeal of it) difficult.

A investigated what makes EV charging so frustrating. The first major hitch they found was the physical state of the chargers: , glitching, or . The report also mentioned slow, unreliable communications between chargers and cars — something I’ve even experienced in my own EV adventures. It can take repeated attempts, unplugging and plugging-in the car, until the two start to play nice.

That is, of course, assuming the two will ever talk. With myriad EVs coming from all manner of companies, Automotive News found that it was difficult to develop charger software that worked with every car. The article stated this as — when one brand builds the cars and the chargers, coding them to cooperate is trivial.

Owner education, too, was cited as a concern. Gas-powered cars parking in EV charging spots is widely regarded as a dick move, but a subtler issue comes when owners of slower-charging EVs take up fast-charging spots. A may not be able to handle the high charging speeds of a , but the Bolt owner may not know — and may default to the charger with the biggest number on it.

that these issues, plus even more relating to fees and payment processing, are hindering EV adoption. Range anxiety is one thing — many people can be convinced that they do not, in fact, drive six hundred miles on their average commute. But horror stories of charging issues still turn prospective buyers off from going electric, and are yet another factor holding up the full-scale EV transition.
