According to Green Car Reports, the charge-bot finds the car, plugs in to charge it and when it's done, it goes back to its default location to charge itself from the grid, solar panels or even energy storage systems.

The robot's two external screens can also show advertising, which the company can use for extra revenue.

EV Safe Charge plans to manufacture the Ziggy robots from 2023 and claims to have gotten interest from a few locations, including the Opera Plaza in San Francisco and the Holiday Inn Express in Redwood City, California.

The company aims to be the first that will launch a commercial version of the mobile charging robot, as other industry members tried different concepts in the past, such as Tesla, who experimented with a snake-like charger that could plug itself into EVs for charging, but the solution was not mobile.
