Hello all,

I’ve seen several posts on people getting battery replacements. Here is a rundown of what I have been experiencing. My dealer is 350 miles away so before going I thought I’d poll this audience.

2020 SR/F, demo
Updated all firmware
Bike lunges due to regen dis activation at 98-100% charge
Bike says it will fully charge in 3 hours at 1.3, but then sits at “100%” or whatever I set it at for several hours after and is obviously still charging

Most concerning, if I am at 40% or below and get on the highway going over 60, SOC drops like a rock. Once it puts me at the limiter and I pull over, it magic charges upwards of 25% over the next hour.

Zero asked for my logs but is essentially saying take it to the dealer. I want to wait until at least winter (warrantee good until 10/24).

Any feedback or experience would be very useful.

You'd have to talk to them to get a real answer if you qualify BUT....

since you notified them of a problem, if you wait too long ie months to take it in, they could possibly say, well you didn't bring it in when the problem was small... not it's cascaded due to your negligence, so we are no longer covering it....so be careful about waiting too long.

Answer: I hope so, or else they solve what the issue is, but you kinda have to take it in.

I think that regen deactivation toggling is normal when the bike is fully charged. It happens on mine for a block or two when I first set out, on the rare occasions I need to charge it fully. Its not pleasant but I think that's what they all do. Might have been better to have the display set a banner that says "Regen Disabled over 97% SOC " or some such, then just have it off until the battery drops. The surging scared the sht out of me the first time it happened.

I think that regen deactivation toggling is normal when the bike is fully charged.

No regen when the battery is full or close to full happens to all EVs.   Happens in my Chevy Bolt.  Happens on both of my Zeros.   There just isn't anywhere for the regen power to go so it doesn't create any.

No regen (or sudden regen cutoff) at high SoC is normal. The battery touches the upper voltage limit.

Taking a long time at 100% could be fine, that depends on what the bike is doing. Did you check wether it's actually still charging? (what is the charge power or current at that point?). What is the cell imbalance on your bike typically?

if you are getting a large cell imbalance on your bike that is taking a long time to correct, over and over,  that tells me that something is not right there.  You got a weak  cell or something is taking them down and that's going to be an issue to contend with not too long down the road.  or am I way off base on that thinking??
