🎶🎸 'I want to ride my bicylcle' ist nicht nur eine Strophe aus einem bekannten Queen Song, sondern auch in 🇩🇪 Programm. 🚴 #SchonGewusst: Bei uns gibt es mehr Fahrräder als Einwohnerinnen & Einwohner!
Eine Studie des Zweirad-Industrie Verbands (ZIV) zeigt, dass der #Fahrrad- bzw. E-Bike-Bestand im vergangenen Jahr auf 84 Millionen angestiegen ist. 🥳
Darunter sind 11 Millionen #EBikes, welche auch im Rahmen des steuerbegünstigten Dienstfahrrads gefördert werden.
The UPP battery I got for the tandem #BikeFriday project has been okay, afaict (or might be part of the hangup that happens in regen braking), but I hate that it has this XLR plug with that fiddly sliding plastic cover, also seems to lack a fuse, unlike the previous generation of generic downtube pack (dolphin) that had a barrel connector charge port. I can see the argument against the barrel connector, but why have a 3-pin port and not include a thermistor? #eBikes
in any case, I'm thinking of a generic charge controller to cut off at a given voltage or temperature, and maybe report the charge level over http / ethernet, if anyone has hardware+software suggestions. I think there's a teensy in a box here somewhere, maybe lacking an ethernet module or something, or do we just do a raspberry pi with a whole linux stack and plug in 3-5 somethings on USB for the voltage sensing and relay thingy? (not all e-bikes are in the same spot but maybe 15ft of usb...)
