E-Moss is testing an electric bus that was equipped with a wireless charger, It is usually electric cars that are equipped with these, but buses could also benefit too.
The type of charger the bus is equipped with is an induction charger. Induction chargers operate by using inductors to generate an electromagnetic field which another receptive inductor in the bus uses to generate electricity.
This bus is can be charged by plugging in overnight or via wireless charging.
These chargers are not the long-range type (such as microwave power transmitters) which transmit power without wires to devices hundreds of feet away, but it is a convenient short-range type that is set up in the bus lane so that the bus automatically starts charging as soon as it drives over it at a stop.
In other words, they partially charge whenever they stop to pick up and drop off people. Of course, buses make many stops and all that charging adds up.
Buses Can Benefit More from Wireless Induction Chargers than Cars
Electric cars, unlike buses, don’t tend to have completely predictable, fixed schedules. So it’s not surprising that on-road wireless charging for buses is popping up first, but roads may soon be equipped with induction chargers that could charge cars at stoplights, as well.

Former Tesla Battery Expert Leading Lyten Into New Lithium-Sulfur Battery Era — Podcast:
I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
