Some time ago I started noticing that my Plus doesn't always slow down when I let go of the throttle. It seems odd that it sometimes does, and sometimes doesn't work but I'm beginning so suspect that it has to do with the temperature of the batteries.
The Plus doesn't warn about regen being off (contrary to what I saw in Gavin's post
on his Empulse) but that post got me thinking.
Lately I've driven a lot with the dashboard set to "detail view" (don't know what it's officially called - you can get it by pressing the start button for 10 seconds or so, when the bike's live). It looks like this:
It seems that if Tmin
is below 10C, regen doesn't work, but above 10C it does work. (That's 50F for those on the other side of the Atlantic).
When the regen is working, besides feeling the bike slowing down a lot more, also the number at I:
goes positive, indicating current flowing into the batteries instead of the other way. In the picture, even while the bike's standing still, I
is negative, perhaps because of the battery heaters being on?
Also, I found that speeding in cold weather, quickly cools the batteries. It may need something to cover the bike's air intake, like in the old days on a CitroŽn 2CV:
