Pics and Vids / Re: How to Adjust Your Zero's Belt
« on: June 09, 2023, 10:45:02 AM »
Has anyone ever aligned the bell on the front pulley?
As I see you need to adjust the motor by 4 screws on the right and left side. Right?

I did it.
0% Heavy cell balance
Now I will measure how much goes into the battery and hopefully better Balance after that. Lowest cell was at 3218..

Hey Guys,
I tested furthermore now but still haven't reached 0% yet. But soon.
What I noticed is
From 100% - 30%
110-115kmh on Dash 1% per 1.3-1.5km. Would do 130-150km
75-85kmh on Dash 1.7-1.9km. Would do 170-190km
But!
From 30% on I lost 1% per 0.3-0.9km. And since then it's not really the point if I ride 80kmh or 110kmh.
Second how exactly are the measurements in the app?
I drove 95km total have 49% left and the app says 4.63kwh used. Would be 190km total with 0% left and 9.26kwh used. But my battery should have 12.6kwh.
So does the app lie? Soon I can tell how much the Wattmeter says when I charge from 0-100%

Zero Motorcycles Forum | 2013+ / Re: Strange SoC behaviour 2017 DS
« on: April 30, 2023, 02:53:04 AM »at first also I thought that it was strange behavior..
it's just normal on such models (i have 2021 S which is basically same bike) and it's called "magic battery".
it was slightly improved on latest updates but it still happens.
in my case it happens when i start a ride in warm condition then ends in much colder environment. SoC drops hard.
Then when I get home and attach to outlet, SoC instantly raises by about 10% in 10 minutes which is no sense (i have no charge tank).
this let me think that battery returns to "normal" temperature then display actual SoC.
from a engineer point of view I suppose that this is due to temperature which lowers voltage to cells. Even if BMS is aware of battery temp, engine temp and electronics temp, continue calculating SoC based on Voltage only and not considering temperature drifting so from their point of view available capacity is much lower than before.
This also explains why you still see a good consumption (50 Wh/km): you're consuming same but your battery instantly got smaller.
The magic battery is a failure from Cypher III.
My 2021 S had it once and other problems with range. I guess there is a problem due to my BMS. I have also opened a topic for my problem too.

« on: April 29, 2023, 05:32:29 PM »Buy a meter that will measure the total energy consumption such as this:
https://54energy.net/products/digital-wattmeter-220v-110v-ac-power-meter-electricy-consumption-energy-meter-eu-plug-power-kilowatt-wattage-electricity-meter
Run the battery down to 0%. Charge to 100%. Find out how many kWh were input into the battery. If it is close to the nominal battery rating, then your battery and BMS is probably fine and the lack of range is related to another issue. If the reading it way lower than the nominal rating, then you have an issue with your battery.
Alright I'll report.
Real usable capacity should be 12.6kwh right? So the Wattmeter should measure around 12.6kwh +-20%.
I think zero guarantee at least 80% capacity in the first 5 years. So 12.6kwh -20% should be at least 10.08kwh.

App shows 3.14kwh per 65km.
Battery capacity should be 12.6kwh. If we continue with the app I should reach 260km.
In real I needed 34% for 65km. Would be only around 195km maximum range.

Hey Guys
Yes it's a 14.4kwh battery.
Here a Screenshot from zero spy. I think AH has to be more. Like 126ah instead of 124ah.
I will build a cable to read out BMS directly too.
I have compared with other Zero S Riders in Germany they all got at least 180km range. I end up with 130km. My FXE 22 which I own before reaches 110km same drive habits. Which lead me to the point that the S with double battery capacity should reach 220km.
Onboard Charger isn't Really charging with 1300/1400w too.

Could it be that Zero 2018 above have many problems with die Battery or BMS itself?
I own a Zero S from 2021 and I've got problems with the range.
Zero says 113kmh would last for 143km.
I have tested it and I only got 100km. With city 130 maximum.
I think that's not okay. What I noticed too at about 30% I lose 1% each 400-800 meters.
Above 30% I lose 1% each 1km - 1.5km.
Once I had a very strange moment. Drove 5km and paused for 3 minutes. Keyd the bike off. 33% was left. Keyd on 18%. Range left decreased as well. I came home with 0% and 3km range left. Not funny isn't it?
I already tried bms reset. Left button works. Right button nothing. Already tried to drive to 0% and charge to 100% 3-4 times. Nothing changed. Some say cell balancing can take up to 24 hours??
I could provide BMS and MBB logs if needed.
As far as I know the 2021 bikes had many problems with faulty bms. Just see FXE Models for example.
