Yes, as usual, the language is convoluted but the patent application suggests that Shimano is at least considering bringing a non-contact charging system to the cycling world. “The rechargeable power source of the bicycle component can be conveniently charged without using an electrical cable.” As you use each component its power will be depleted, of course, so sensors will ensure it is automatically recharged from the charging device.
Nah. It’s just new fishing gear.
