Rivian Automotive Inc. said it will now sell its electric delivery van designed for Amazon.com Inc. to other customers, a move to boost revenue from fleet operators as consumer demand for battery-powered cars slows.

If it gains traction, the commercial van could become a bigger source of revenue amid a broader slowdown in consumer EV uptake.

Rivian is opening up sales of its delivery vans to fleets of all sizes in the United States, the electric vehicle maker said on Monday, more than a year after ending its exclusive deal with shareholder Amazon.
