Are we really ready for the electric vehicle revolution? A new study says no. Researchers say that charging EVs at night could cause major stress to power grids.
If EV drivers charge their cars overnight when they are not using them, it will increase peak electricity demand by up to 25 percent. They say that power grids are not currently capable of handling that. They single out California, which imports a lot of its power from other states.
Instead, they say, drivers should charge their cars during the day either at work or at public charging stations. But electricity rates are typically cheaper at night so how will states convince drivers to do this? That’s the rub. The researchers say that states need to rethink electricity pricing.
