Several major fast food and convenience store chains have recently announced a big push into electric vehicle (EV) charging, a trend that could accelerate efforts to expand the country's embryonic charging infrastructure.

Why it matters: Automakers are finally getting serious about electrification — yet many would-be EV buyers want more assurance they'll be able to find chargers when they need them. Project Ev Charger

Driving the news: Convenience store chain 7-Eleven recently launched its own EV fast-charging network, called 7Charge.

Catch up quick: Fast food giant Subway last month announced long-term plans to build car-charging "oases" replete with green spaces, playgrounds and more. (Electrify America, one of the foremost charging-specific companies, has similar ambitions.)

The intrigue: In a press release, 7-Eleven touted its potential to address the charging gap.

Be smart: Stores that install EV chargers will likely make a decent buck on charging fees, just like gas stations take a cut when you fill up your tank.

Yes, but: Franchise chains have only so much control over what individual owners choose to do, potentially limiting their ability to become major players in EV charging overnight.

Level 3 Ev Charger The bottom line: As the Biden administration pours billions into incentives for expanding the charging infrastructure, your favorite fast food chains are looking to take a big gulp of that cash spigot.
