Riding your e-bike way out beyond the grid doesn’t necessarily have to mean you’re going to end up having to pedal it without electric assist all the way home if you don’t want to. Some crafty e-bikers have been experimenting over the years with ways to charge their batteries while on the go with solar power, but as far as I know, it’s only very recently that a few e-bike brands are addressing the solar charging angle themselves .
That’s not to say it’s going to be simple, though, as almost every brand of e-bike seems to have their own style of charging connector, and the different e-bike models will have varying battery voltage and capacity, plus each model’s motor and controller will differ in how much power the levels of pedal assist use, as well as the power output for when in throttle-only mode.
The charging system includes a single 100W solar panel on the top of a bike trailer he pulls, plus a 200W solar panel that is stowed in the trailer until needed, plus a charge controller, which then feeds the battery. According to the video, with both the solar panels in use the battery management system limits the input to 160W.
