Title: Zero S 2014 ZF11.4 - Sudden shutdown
Post by: Psycopyro on September 08, 2017, 11:31:24 PM

I traded my XJ6 to a Zero S ZF11.4 one month ago.

On the way to go to work my Zero suddently stopped. I didn’t know that the flashing sequence may give an indication on problem, didn’t write down...
My batt was around 30% at that time, power limited despite a full power custom mode, heated grip on, no high temperature light, gentle ride.

I have travelled 1000km so behaviour of power management is not complety clear for me.
Typical travell is : 30km back home ~70%, 30km to work ~40% charging to 100%.

I have noticed the following, don’t know if normal :
Full power from 100% to ~40%
Under ~40% power is limited, top speed seems limited by available power.
Another thing that might be interested to report, I stopped (once) charging around 92%, 2 hours after, battery was 100%.

Note : no power tank, no quick charger, oxford heated grip installed.

Thanks in advance

Bad to hear  :(

Normally the battery (if it is the root cause) has 5 years warranty.

Regarding the charging to 92% which changes to 100%, this is "normal" messy display, don't worry.

Try to find the error code sequence, try to download the log (with the Zero App), then we may come closer to the cause.

Has your zero been soaked by heavy rain (not necessarily Harvey or Irma...)?

Powerful utility!

Errors codes that have been logged: 0x45C5 (High capacitor), 0x46C3 (??), 0x54C1 (DSP Overvoltage), 0x45C8 (Vcap above rated max), 0x4981(Throttle Fault) and finally 0x5101 (Line Contactor o/c).

I have a
"Low Chassis Isolation" on cell 3-4-5-6
and
"Batt Dischg Cur Limited" with the highest value of report at 69% SoC, which seems to me not normal operation...

Temperatures are around 20°C and weather is light rain.

Not an optimistic log...

Did you try pressing in both the reset buttons in at the same time? The ones under the rubber plug behind the front wheel.  That's all it took to solve my problem where the bike would not charge or run.

You can read about these reset buttons  in the Unofficial Service Manual.

Log sent to Zero, BMS resetted. Ride and See.

BMS diodes sequences is not reported in the manual, 2sec off 50ms (i guess) on.

Thanks guys for your help.

We should document BMS blink codes as we learn them here:
