Installing high-powered EV chargers everywhere doesn’t necessarily mean they’ll actually be used by drivers.

That’s what a new white paper from Kempower, a charging hardware and management software provider, found.

If charging networks want to make money and keep the lights on, they should focus on offering more choice, not more power, the paper said.

Megawatt charging is very cool, and a sub-10-minute top-up can add hundreds of miles of range to a compatible EV very quickly. But power isn't everything, according to a white paper published by Kempower, a Finnish company that builds EV chargers and provides charging management software to charging networks.

The paper, based on North American charging data extracted from the company’s ChargEye analytics platform, argues that operators will make more money if they focus on installing more plugs at their stations, even if these stalls offer less power than competing locations. The number of plugs at a site correlates strongly with utilization, Kempower says—more so than the total installed power.
