What you're referring to is "range anxiety," and it's a common concern among prospective EV buyers. Electric vehicles batteries last for a certain number of miles before needing to be recharged, but that number will depend on the model. In that way, it's not so different than the differing miles-per-gallon rating of gas-powered cars. And like gas mileage ratings, EV range has been increasing in recent years. The median range in 2020 was more than 250 miles, according to federal data. And while most of EV charging takes place at home, more public EV chargers are being built. That includes plans for the northeastern Minnesota region.
