Charging stations play catch-up with automakers' electric ambitions

More electric vehicles are expected to be sold in the United States over the next few years, but the infrastructure to charge those cars is just starting to take shape.

Most major automakers are betting big on electrification, with some promising to do away with internal combustion engines altogether. The push to electrify is driven largely by stricter emissions regulations in the U.S., Europe and China as they address pollution and climate change.
