Zero Motorcycles Forum | 2013+ / Re: 2023 Zero DSR/X not charging

You can download the log fiels with the app.
They are binary and you can analyze them with https://ernstgl.github.io/ZeroGen3LogParser
You can see the voltages of highest and lowest cells.

The ocv is some estimate for the voltage when the current was zero. While charging the cell voltage is higher because of the internal resistance.
There are no labels for columns because the meaning depends on the type of the entry. There is an explanation on the website of the decoder which has to be unveiled by clicking.

Zero Motorcycles Forum | 2013+ / Re: Log files for SR/S and SR/F wanted
« on: March 19, 2026, 04:37:34 PM »
Have a look at https://ernstgl.github.io/ZeroGen3LogParser/
You can download it and look at the javascript inside - it has comments.
Maybe you find a better solution.
The logfiles of all FST platform bikes (SR/S, SR/F DSR/X and newer S, SR, DSR) should be of the same  format.

That is awesome, thanks!

What should we check to know the battery status?
I guess it's cell balance in the BMS log. Look for types 75 to 77. There are values around 4000. That's cell voltages: min, open circuit and max.
The difference between max and min is the cell balance. Mine is around 2 mV (4111 - 4109) after a full charge.

I have written a Gen 3 log file parser if anyone is interested:

Would be interesting to see results of someone with battery problems.

Zero Homepage (Technical Specifications/DRIVETRAIN) says all rear sprocket have 90 teeth.
Motor sprocket for SR/F and SR/S has 20 teeth.

Shouldn't charging stop when you turn the motorcycle on?

Remember that you may need a dealer to install this.

The BCB will charge from 0 to 95% in 1.15 hours in an ideal temp range.
How is 95% charge possible in 1.15 hours (at 6kW)?
6kW for 1:15 hours gives 7.5kWh.
That would mean 100% corresponds to just under 8kWh - for a nominal 14.4kWh Battery?

On my 2023 SR/F when charging at 6.6kW it takes around 1:20 minutes for 1% of charge.
So I would guess 2 hours for charging from 0 to 95%.
For the 14.4 kWh Battery and 6kW charging I would expect similar times.

Here (https://zeromotorcycles.com/owner-resources) you can find a service manual for the 2023 Model DSR/X (and others). That migth help.
