Zero Motorcycles Forum | 2013+ / Re: Charging Problem with my SRS
« on: February 14, 2023, 04:09:20 PM »
when you charge at home with 220v you use only one phase and one charger, with 3 phase charge station you use 2 phases and 2 x 3kw chargers.
now to understand where is the problem ... is not easy, maybe the charge station have problems on the second phase and charger disconnect until voltage is stable.. but if you find the same problem on all charge stations i think the problem is on the bike. 
my suggestion is to remove cables from second chargers, check connectors humidity and apply dielectric sillicon grease if is required... maybe is only oxidation problem.

I agree with Zelidar,
i drive with all sliders to max to have a good regen (and save some brake pads).
the reason why you can't have more regen is because rear brake light do not turn on automatically...

for Specter,
torque limiters are hard-coded in the MBB, acutally i have

Point rpm     forward scale              regen scale
             (ppm/pctX10)               (ppm/pctX10)
 0    -1000       0                      0
 1        0    1000                      0
 2      500    1000                     25
 3     1000    1000                    250
 4     6500    1000                    250
 5     7500    1000                      0
 6     8500    1000                      0

so regen is disabled after 7500 rpm and limited to 25% instead of 100%
forward torque have no limitations.

After the previous posts i made some tests to verify max speed, since is the easiest parameter to verify without a dynometer..
i lifted rear wheel and adjusted riding modes, in this way wind and road do not affect results, and i made a video to see rpm and max speed on dash

results:
TWlua2lvbmUAALx46AOo/eD8AQCCHAUUUAAAAAAA - custom mode 124mph (speed limiter slider at max)
rpm limiter set to 7298
max rpm on dash 7794
max speed on dash 198 km/h

TWlua2lvbmUAALx46AOo/eD8AQBIHAUUUAAAAAAA - custom mode 123mph
set rpm 7240 
measured rpm 7730
max speed 196 km/h

TWlua2lvbmUAALx46AOo/eD8AQAMHAUUUAAAAAAA - custom mode 122mph
set rpm 7180
measured rpm 7681
max speed 195 km/h

U1BPUlQAAAAAAAHI6APo/uj+AQBMHQMBMgAAAAAA - sport mode
set rpm 7500
measured rpm 8034 
max speed 207km/h

so, bike add +500 to the rpm limiter set in driving modes and that's it... sport mode definitively have higher rpm.

about max power...
no idea about 200 vs 120 values.. and no idea if MBB reduce power or not..
for this test a dynometer is required.

I made some reverse engineering about driving modes on my SR/F 2020 premium MBB firmware v27
you can set values from application and this is ok, but results...

attached snippet of current driving modes dumped from MBB firmware
my TEST preset sliders are all at 100%, application write 100% to the MBB (i made canbus trace to confirm), and MBB convert it to:

Mode  Name      Fwd   Fwd   Cst   Brk   TCS   ABS   Max   Color Zero  Zero 
                 Pwr   Trq   Rgn   Rgn   mode  mode  RPM         ppm/  pt   
                             Trq   Trq                           rpm   %x10 
  0    RAIN      50    550   -250  -250  2     0     5888  2     20    80   
  1    ECO       30    625   -600  -800  0     0     4416  1     20    80   
  2    STANDARD  50    875   -260  -400  0     0     6475  4     20    80   
  3    SPORT     200   1000  -280  -280  1     0     7500  3     1     50   
  4    TEST      120   1000  -600  -800  1     0     7298  5     20    80   



max rpm is limited for sure in the custom preset,so max speed can be archieved only in SPORT mode
max torque is set to 1000 properly
power... 200 vs 120.. lower power at high rpm?
ppm/rpm and pt%x10, something related how power and torque are applied, no way to change them from app.

as result you must drive this bike in SPORT mode to have the correct power and max speed, but in this way you cannot have high regen torque.


to build this table you can convert mime encoded debug messages from diagnostic port (when you modify a preset in the app)
DEBUG:   01/01/1970 00:05:14.654  ../src/Application/zero_mbb_ridemode.c          : line   336 - Encoded to RUNPAAAAAAAAAAAecQKo/eD8AABAEQEUUAAAAAAA

in a readable form using a small app i made.

what do you think? what preset do you use normally?

yes, zero console is not standard,
you can use this small program i made to interface it
https://drive.google.com/file/d/1xFppbBsfCtPkoJzsk0wwxbPf_gVOVHPW/view?usp=sharing

 "open" the FTDI com port connected to the bike and type the comand or select the tab with pre-coded commands to show data.

while waiting to receive the ttl cable for the ccm diag
a person from the French forum shared a link for me to connect the ccm.
here is my data
What do you think ???
<data>
<item>

<software_version>200416</software_version>

</data>

i see you are on the same fw 2020.4.16 as i am, and my ccm is not working too, maybe this EU  firmware is bad and who have it... you know..

I have the same problem, SR/F MY2020 MBB27 MBS21 latest android app, but i think it's not relevant since you can check online data with zengo apps or browser

disconnect 12v battery, my ccm will work until you ride the bike, than it will die until the next 12v power disconnection.
there is a service recall
https://dot.report/bulletins/10216888
but dealer report is only for usa bikes....
anyway my ccm  is fw_ver,  2020.4.16, you can read with diagnostic serial cable.

Model Year 2022 Zero SR/F/S CCM Firmware Update
Service Campaign

https://dot.report/bulletins/10216888

this is the real explanation, i hope this will fix CCM :o

I just spent several months getting a new CCM fitted (under warranty).  It had to be coded to the bike which unfortunately the first that Zero sent out was not.  But after successful replacement it updates the Cloud status fine, but after the bike is keyed off for a couple of hours (next CCM update basically) then the SOC goes to 0%.  Key the bike on and leave for an update to occur and it is correct again.
It feels as though this is an issue with the new CCM sending back the wrong status when the bike is off.  But the dealer is stating this is a known issue with the App (Zero NextGen app that is). 
Anyone else with any further info on this issue?  I can't help but feel it's a simple config problem.   :o

my ccm is faulty from the beginning ( february ) and i have open a ticket to my dealer, and i call it every week for status... but at today nothing.
my current ccm have 2 problems, it never report soc % and charge status to the server,
but the worst problem is that after a server position update ( with bike in motion) it hang, simply ccm go to low power mode and never wakeup, to fix this you need to disconnect 12v battery.
if bike is stationary it update server position without issues every time you turn on key.

running a canbus trace on the communication lines, the bike send soc % and fw ver to the ccm every sec, and ccm send back the info you see in the diagnostic.
as soon it hang it disconnect from bus and all the data transmitted from mbb is not captured.

i have also found canbus messages (id253) with soc 0% sent to the ccm  at key on, this is likely the cause of the bad soc% reported to the server (if ccm update the server with this value)...and i think it will be addressed by a new MBB firmware soon or later... (i'm running MBB v24)

p.s you can check the real data sent from ccm to the server with the following info https://www.electricmotorcycleforum.com/boards/index.php?topic=9520.0
cause app can be bugged too :'(

Zero Motorcycles Forum | 2013+ / Re: Zero Next Gen App v2.2.6

Hello!
i own a sr/f 2020 premium,
application update on android worked ok but app crashed, so i had to delete the app and reinstall it from playstore because of cache bugs.
firmware update to MBB v24 and BMS v20 worked properly, only takes a lot of time at 100% waiting the complete message...don't panic!
i didn't test yet the max speed problem on riding modes, but i noticed a strong reduction of regenerative brake,
my custom mode have regen at 100% and usually i don't need to use brakes... after the update i have to brake... any one noticed the same?

Nope! I dont see a difference with regen, except that i felt that the throttle based regen is a bit more smoother than before.

Thank you for the feedback,
another thing i found is that on main application page you see always "current riding mode:rain" but dash shows the correct mode, you can activate different modes from app, and dash will set properly, but also in eco mode where regen sliders are at 100% the regen force is ..let's say half than before.
