Controllers and ebrakes that would do progressive regen

[elt93]

Hi,
I am currently using the cut-off ebrakes from em3ev on an infineon 12fet and MXUS 3000 ebike. Are there any ebrakes/controllers on the market that would allow for progressive regen. The more you press the brakes the more regen you obtain?
Thank you for your help!

I'm not aware of anything like this on the market. People have retrofitted hall sensors (variable, not on-off, like in cutoff levers) and magnets to their levers, so you could try that if you're looking for a project. I just use a separate thumb throttle for braking.

From the research Ive done on the Adapto controllers (Max-E) they do provide progressive, programable regen.

There is the Kelly that has this option on regen braking but I know that you should first activate the brake cutoff and then it will be possible to activate a some kind of throttle that will module the amount of brakes.
Anybody can confirm this as im not so sure and anyone knows how adapto makes this modulation on regen?

Oh, sorry, I answered the "ebrake" part of your question, but not the "controller" part. In addition to the Adaptto and Kelly, the ASI controllers from Grin (PhaseRunner and BAC2000) will do this, as will Sabvoton and Mobipus. These are all pretty pricey compared to a 12-FET Infineon. I think less expensive options are available, but I don't know what they are specifically. If you'd be happy with fixed regen, I think that's becoming fairly common among mid-priced controllers.

You can also build a Lebowski controller (no kits or complete units are available that I know of, but various PCBs for the brain/power boards are, if you look up threads with Lebowski in the title).

As for levers that have an analog output rather than just switching, I'd personally setup an analog sensor on my existing good-quality regular brake handles, or on the brake arms or cables.

Or with some controllers that do analog braking, the throttle can control braking force after you've engaged a regular ebrake switch).
