@crispius@mstdn.fname.ca The regen works very well and is very strong, though I have yet to see just how much regen it takes to get X amount of charge back, etc. I will have to do some hilly riding to get a better impression of it.
It can be controlled in a variety of ways - there's digital brake levers that just have an on/off point to both cut off the motor if it's pushing and to begin regen at a programmed level. There's analog brake levers, which I have installed as my L brake lever (on the trike both brakes are on the front, so we always or are supposed to always use both brakes at the same time) - this lever increases the regen the harder I brake with it (as well as cutting off any motor assist at it's beginning point as well).
I also have a bidirectional throttle as part of my right grip, which I swing downward for forward throttle or swing upward to engage regen in a reverse-throttle manner.
Most of the braking can be done just with regen, providing the battery (or batteries) aren't 100% full.
On the car front, I have a plugin hybrid EV and generally it gets charged at home. The problem with doing so when living in Aberdeen is that generally all trips start by going down hill, so unless I could catch unplugging the car at the right time, the batteries were usually too full to allow any useful amount of regen. But yes, when you can use them, it's awesome to be able to extend the range (or in my vehicle's case, keep the charger off longer).
I bought a fairly advanced e-bike charger, programmable, and I think I'll be doing an 80 or 85% charge as the norm to keep the # of charge cycles down, allow for regen room, etc.
