As electric vehicles hit the road around the country, hundreds of thousands of Americans are beginning to learn the ins and outs of car charging: how to install home chargers, where to find public charging stations, and how to avoid the dreaded “range anxiety.”
But as EV owners plug in their cars, there is a looming problem: pressures on the electricity grid if most drivers continue to charge their electric cars at night.
According to a new study from researchers at Stanford University, if EV sales grow rapidly over the next decade — and most drivers continue to charge their electric cars at home — vehicle charging could strain the electricity grid in the Western United States, increasing net demand at peak times by 25 percent. That could be a problem as the West struggles to keep the lights on amid heat waves and rising electricity demand.
