Supercharging More Electric Cars Risks Crashing the Grid—Here’s What Might Help

Scott Moura is an assistant professor in civil and environmental engineering at UC Berkeley, and a proponent of “smart cities”: urban centers that coordinate among their infrastructures. Traditionally, Moura says, cities’ electric and transportation grids remain separate, but with the advent of electric vehicles, the networks are “colliding.” The collision couldn’t be clearer than Moura’s example of a supercharging Tesla coming online, which he says would “feel” to the grid as if 120 houses came online for only half an hour. “It’s like an entire neighborhood popping up in the middle of a city, and then disappearing,” he says.
