Zero Motorcycles Forum | 2013+ / Re: 2013 ZERO FX Modular Battery Pack Exploded

Any idea how to get a Modular Battery Pack out of the frame once the battery pack has seared off the screws due to rapid expansion?

Opened a file with https://www.cpsc.gov, they want to come out and take a look at it.

Are you safe and un injured?

Zero Motorcycles Forum | 2013+ / Re: Fast charging options for the GEN2 platform in 2024?
« on: June 20, 2024, 12:03:22 AM »
I used 3 elcon chargers, and the onboard charger; which gave me about 10kW.
It worked fine at the charging stations in the Netherlands.
Did use all the three phases on the charging station. And added another charge connector on the bike which connected to the Battery via the SEVCON + and - terminals.

Ah Yes,

Im quite sure it is the tip over sensor. I was facing the error, with a little bit of panick since I took my bike apart. but then I remembered the tipp over sensor.
Therefor I found a way to stop the error from occuring  :)

Zero Motorcycles Forum | 2013+ / Re: Spare Belt?
« on: June 01, 2024, 10:14:56 PM »
I bought a spare belt, and luckaly I did; cuz my belt broke at 16000km  :(
But with the bike at home it was doable to change it myself; even on a gen2 bike

Zero Motorcycles Forum | 2013+ / Gen2 Error code 23
« on: June 01, 2024, 09:52:36 PM »
So I found a possible definition for Error code 23.
I wanted to submit it to: https://zeromanual.com/wiki/Gen2/Error_Codes#23 but I am not sure how.

I found out that if your MBB is not in its normal position; when the bike is turned on; it will give an error 23; see the picture  :)
You will still be able to drive the bike; but you will see the error 23 and dash error blinking.
This is propably not the only way to get a error 23.

Zero Motorcycles Forum | 2013+ / How old is your zero?
« on: May 26, 2024, 06:31:45 PM »
Also because I am wondering how reliable a Zero is. But also because forums usually discuss problems. I thought this could add a positive note.


So the question. How long have you used your bike?

Bonus.
  • version:
  • bike production year:
  • years you have used it:
  • km you have put on it?

Sadly the time stamp does indeed line up with the time i lost power.
Now it also happens when i just turn on the bike without driving  :'(

I havent noticed the Bmvolts and Cmvolts yet till you mentioned it just now! I will look into that a bit more,

Zero Motorcycles Forum | 2013+ / Zero S 2019 - Sevcon CAN Link Down
« on: May 16, 2024, 09:13:05 PM »
Any one encounterd Sevcon CAN Link Down before?

The first time it happend; the bike was charging overnight; So i did not notice it.
Than it happend when I was driving. I suddenly lost power.

Because the Logs showed the SEVCON CAN link was lost; my first tought was that it could be a broken wire.
I checked the wiring; and I could not find any damage. I also tried to see if the CAN Link would go down; if I was fumbling with the CAN wirering. Sadly this is also not the case...

I'm a bit afraid that my SEVCON is dying.... Did anyone have a SEVCON dying in 5 years or after 21.000 km?







the first time it happend to my bike was apperently when it was charging. But only now I am noticing it when i'm driving.
It seems like

« on: May 06, 2023, 01:04:44 PM »
Dear Domingo,

could you send me the 2 files with bin extension?
Than I could try to run them through my python / excel file.

Are you able to make the one-way commute of 45 miles? (up and down, do you drive up a mountain?)
How much SOC does your dash show when you do the 45 miles commute?


It is not really possible to determine range expectations from the logs; This since the log does not show how the driver is accelerating and if it is raining.
It could only give you a broad estimate.



Battery health
I check the battery health by charging the bike till 100%, than driving it till it won’t turn on anymore. (make sure the battery is empty around your house since you will be pushing it home).
Then I look at the "Discharge level xxx AH". If you have a Nominal battery capacity of 12.6kWh the maximum "Discharge level" should reach about  126 Ah = 12600Wh / ~100V (theoretically)

Last week I drove till 0% SOC on the dash, 5% SOC in the logs (the SOC on the dash is not the same as the SOC of your BMS), and I had a discharge level of about 111 Ah.

 04899     09/16/2022 01:54:42   Discharge cutback          79%




Range estimate
If you really want to have an range estimation…. Which will only give you a broad general indication…
you have to drive the rest of the SOC under the same circumstances etc.

You can use the starting SOC% and ending SOC% of a ride, together with the starting ODO km with ending ODO km.
Your expected range = (ending ODO km - starting ODO km) / (starting SOC% - ending SOC%) * 100
Your expected range = (7207- 7153) / (72 - 34) * 100
Your expected range = 54 / 38 * 100
Your expected range = 142 km

142 km = 88.2 mile

Bike use
Having calculated all this; from your logs; and looking at my own experience with my Zero S 2019.
Here in the Netherlands I would not worry about a 45 mile commute driving 70 mph in all weather conditions.
Do have to charge each 45 mile commute tho.

« on: May 04, 2023, 01:59:30 PM »
Dear Stivikivi,

I would not really trust anything the app says except the current voltage.
When charging at a charging point I also noticed that my bike keeps drawing about 1 KW/h even when the battery is fully charged, not sure why. but it does mean that I’m unable to use a public charger to determine the amount of power that went in the battery if I don’t check when the bike reaches 100%

To check if my battery is still okey I usually check the Discharge level of the logs. There is a "AH" counter. When charging the bike and driving it to 0% on the dash (this gives about 5% SOC), the AH counter should be about 111 AH? (110 x 100V = 11 100 KWh)

The biggest Take away is probably the same as Aaron mentioned. SOC and Range indication aren't an exact science; simply because you cannot predict the future.

For me the bike is quite reliable. When I drive a specific route the SOC usage is usually about the same (a deviation of 5% of SOC on the dash). This holds unless there are strong winds or temperature differences.

So when you know your daily route, and you still have 15% left. You can be quite sure to usually make it. (Disclamer, this is my experiance tho)
