I will continue to charge my battery to 100% as it is likely that the battery pack will outlast me and I am sure that it will certainly last well beyond the time that my Zero gets replaced with a new model. 

Same.  But I do ride it a little most days.

After reading the SR/F owner's manual, I'm thinking about setting a maximum SOC of 95% when charging at work on a level 2 charger since they say the last 5% is what takes 30 minutes no matter what. When I get home in the evenings and plug it into 110v I'll change the maximum SOC to 100% to start the next day with.

At least that's my game plan until I read or experience otherwise.

I think the SRF will have much more control over charging similar if not quite as much as the Teslas.  So for that model any recommendations they have can easily be used.

The older models have at least one problem. They arc when you unplug them while still charging.
When I got my 17MY bike I saw it showed the SOC on the dash while charging which is a great feature.  I started following the "best practices" and was unplugging at 80%.  I always unplug and plug into the wall not the bike but that arcing will cause damage at some point.

I think "if" there is a way to set the app to talk to the BMS and shut down charging from the bike unit itself that should be a high priority.
It may help extend the life of the Calex chargers as well.

The BMS already does this for you behind the scenes. No need to try to go to silly means to preserve a battery that will already last 5+ years in most cases.

What happens if you turn on bike while charging?

[Jarrett]

On my 2019 FX, nothing.  It just goes through the normal sequence, but still shows the charging light.

What happens if you turn on bike while charging?

Motor will not run while charging.  It is not possible to ride  away while there is charging voltage on any electric motorcycle (AFAIK).

Tesla takes this a steep further. It cannot be driven when the charge door is open.

I think my SR would still spark with the bike turned on.

If that's the case something is wrong. Try it.

My experience has been that I have never experienced arcing on my 2012 S, my 2014 S, nor on my 2018 S.  I usually plug in and disconnect the the charger power cord at the frame and have done so a number of times while the bike has been charging.

If you let it charge to completion or near competition wont see much arcing, and if you charge at North American household voltages, less arcing than hot-unplugging at 240v.

[Moto7575]

This is very complicated, for unclear benefits. Why don't they implement a "eco charge" button that stops charging at 85, and that you can switch off when you have a longer ride to do ? Also, this information without any idea of what you risk if you dont do it is really useless. Plus you can't advertise a long battery life and "zero hassle" bike, then explain in the manual that you need to wakeup in the middle of the night to unplug you bike !

[NEW2elec]

That's the point.  You can't sub 100% charge without arcing, which goes against the "best practice" of 80% SOC.

I think they saw this as an issue and that's why you can set to whatever you want on the new SRF.

But also remember this is "best practice" just like the change your oil every 3000 miles in a gas car, if you go a little longer the car won't die but it's nice to give it new oil before it thickens up.

The big take away for me is don't fully charge on a very hot day with the bike in the sun as the extra heat "could" cause the liquid electrolyte to expand to a point it could rupture the pouch.

[DonTom]

That's the point.  You can't sub 100% charge without arcing, which goes against the "best practice" of 80% SOC.

Just do not unplug at the bike until the power is off elsewhere  down the line. IOW, let it arc, but not at the bike.

I was replying to Richard's observation that he'd never seen it arc. Should have quoted that.

Charging to 80% isn't usually my goal. I want about 95%, so my regen works from the start, and I'm going to ride it right away.
