Some say that electric vehicles are the transportation of the future, so it stands to reason that their charging networks wouldn't rely on yesterday's business models. And it also makes sense that in the industry's early days, there's more than one charging business model trying to gain a foothold.
Elon Musk's Tesla Motors has its approach, combining a long-distance corridor EV charging network with home stations for its own car models. But there's another model that started with the around-the-town charging concept that's now reached 28,000 locations, more than doubling its range in the past two years.
ChargePoint, which describes itself as the world's "largest and most open" electric vehicle charging network, now has more than 28,000 total charging spots, and its CEO, Pasquale Romano, likens his company's approach not to Tesla but to another disruptive company: Airbnb.
"Airbnb is the largest hotel chain in the world, and they don't own a hotel. We're the largest electric vehicle charging network in the world, and we don't own a charging station," he told CNBC's "Squawk Alley" on Monday.
