Sometimes, technology doesn’t fulfill its promise. But, other times, it isn’t the tech that let’s you down, it’s the people using it. So one electric vehicle charging company company is experimenting with cutting off people who linger, attempting to “fill ‘er up.

” Recently, I drove a new Chevrolet Blazer EV from New York City to Bristol, Pennsylvania. I figured the drive down to Bristol with my family would take about 90 minutes and, since I didn’t start with a full battery, the return trip would take 15 to 20 minutes more with a stop along the way to charge up the EV some. I was so very wrong.

It took us four hours to get home that night. We were sitting in line for electric vehicle chargers. Blame ill-mannered charger hogs who don’t respect EV etiquette.

It’s like waiting for your table in a restaurant while watching people casually chat over empty plates and half-empty wine glasses. What’s wrong? EV fast chargers – the big tall units that look like major appliances – aren’t generally designed to completely fill an EV’s batteries. They are designed to pour electricity into a battery quickly so drivers can make a short stop and get back on the road after, say, 20 minutes or so.

They’re different from the smaller and more common “slow” or “destination chargers,” in Tesla parlance, that are designed for drivers to park, plug in...

and leave for hours. Fast charging can be stressful for a car’s batteries, though. So, to protect batterie.
