Why Battery Swapping May Finally Become a Part of EV Charging Infrastructure in the U.S.

Ample

San Francisco-based Ample has brought electric vehicle battery swapping to the U.S. The company was in stealth mode for seven years before launching recently with five swapping stations in the Bay Area. Uber drivers in the area are Ample's first customers.

The concept isn't new. A start-up called Better Place launched an EV and battery swapping company after it raised $850 million in venture funding, but it ultimately went bankrupt in 2013. Tesla also demoed battery swapping in 2013 but only opened one station for about a year. Elon Musk said Tesla owners were not interested in it.

Battery swapping is already common in China. Electric vehicle maker Nio, for example, plans to double its network of swapping stations to 500 this year and plans to open stations in Norway as part of its expansion into Europe.

Ample has a different approach, with modular batteries and a focus on fleets. CNBC got an inside look at its headquarters and battery factory in San Francisco to learn how the company plans to bring battery swapping into the mainstream.
