It's what YOU are discussing, but not what was initially raised (using a turbine to recapture energy generated from a moving bike powered by a traction motor or pedal power). Apologies if I've misunderstood.

It doesn't have to. It just defines the MAXIMUM charge rate of the charging point. The reduction in charging current that you describe is a natural consequence of the CC-CV (constant current, constant voltage) charge profile used when charging lithium based battery chemistries.

Okay, but that's not what's being discussed here, is it?

Don't forget, the charge rate is practically limited by the current limit of your own ebike charger. AFAIU, the value of the resistor dictates the agreed maximum charge rate of the type 2 charging point, but I'm not 100% about this. Anyone else have any input?

Oh Christ! I can't tell who's being serious and who's not now. My fault for getting sucked into such ridiculous conversations....

It's not free power! The energy to power the generator has to come from somewhere. Rather than dealing with all the efficiency losses created through energy capture and conversion, why not just use the input energy to power the bicycle directly?

If you scroll down to the feedback on the product listing, you can see a number of individuals using it to successfully charge their ebikes. I think the 'handshake' you mention is just a constant voltage present on the 'CP' pin, dictated by a specific value resistor contained within the adapter...

I just found this adapter on Aliexpress: https://www.aliexpress.com/item/1005006861987045.html AFAICT, it should let you power any device with a UK plug (BS1363) using a public Type 2 EV charger. See 2nd product variation for UK compatible plug. So, who's going to be the first to try it out?....

No harm done. You just discharged the controller's input capacitor when you bridged the battery connector with your screwdriver. A flash and a crack is perfectly normal in this circumstance.

This is Unit Pack Power's new store.... Possibly a rebranding exercise following their recent unwanted press attention.

Do you have a link to the specific Amazon product detail page?

Total utter nonsense based on nothing more than fantasy!

Absolutely pathetic! All that fuss for 1.5mph over the maximum allowed speed limit variance. No wonder respect for the police is at an all-time low.

Yeah, I miss him! I seem to remember that he was widely disliked on Pedelecs, but brightened up this forum with his unique brand of humour.

It contains two hall sensors. All the rotational logic is handled internally and the signal is output through a single wire.

I can confirm that the KT-D12L is a dual-hall PAS sensor. I would usually set C1 to '5' when using one.

I used to have a Honda S2000 for fun, but eventually realised my e-bikes gave me more smiles per mile. Ended up getting rid of it and bought a Volvo V70 instead.

KT controllers are definitely the best of all the 'budget' options available, but there's certainly room for improvement. The PID control required for torque throttle control is more complex than that needed for discreet fixed torque PAS levels. I've never tried the open source KT firmware, but...

I've always been puzzled about the throttle implementation when it comes to KT controllers. If the throttle also operated as a current (torque) throttle, it would give a huge boost in usability and also make them more marketable too.

"Wet winter roads, leaves, manhole covers, and off road, gravel" So a bit of everything really?
