Parts, Mods And Hacks / Re: PP and CP control on a type 2 charger cable
« on: February 23, 2022, 02:29:30 PM »
Hi David,

We experienced the same issue on the day we read your post, having modified a granny charger!  Up to now, we have built a very small relay into the charging handle.  The relay is connected to the 12Vdc adapter and the normally open contacts connect the resistor between PP and PE.  So, when you unplug the charging handle, you disconnect the resistor.  If you use a manual switch for PP to PE resistor, unplug the handle first.  That way, you won't trip the RCD/GFI.

Have a look at our previous posts for the circuit.

Cheers

Gary

Hi Auriga,

Thanks for the information.  I definitely cannot get to the cell voltages from the current menu.  I guess there are undisclosed commands that would access this information, perhaps known only to the 'authorised' dealers.  It has always annoyed me that the automotive, etc, industries keep useful information from their customers.

Regards

Gary

Hi Hans,

I can't remember the exact post :(

It referred to BMS #0 and Bank Voltages #1 to #28 and listed individual voltages like 4147mV.  Should you take some readings with the key off and some with the key on?

Cheers

Hi All,

After experimenting with Serial Port Comms packages, Linux and Windows, I have found that the easiest software package to use is CoolTerm running on a Windows 7 to 10 laptop.  The return key does what is required and the results are correctly formatted.  The results remain on screen after disconnecting the serial cable.

I have been looking at the BMS data by going through the help list of commands.  One thing I can't find is the list of bank voltages that Hans displayed in a previous post.  How do I get to this menu choice?

Does anyone know how to get to any other menus below the top level ones listed in 'help'?

Cheers

Gary

Hi Hans and Auriga,

The last time I tried to download logs to the app, it took 40 minutes!  It is a pity other apps are not available.  Out of interest, how long do you expect a battery balance operation to take?

Cheers

Hi All,

Last week, I charged the bike to 100% and she went into cell balancing mode.  Unfortunately, it took over 40 minutes to do this so I checked the data from the bms.  I have listed the results below, but two values are particularly concerning.  They are:

. - pack_capacity_ah 76
. - lowest_cell_voltage_mv 1977

Does this look like I have a dead cell?

Cheers

Gary

Hi All,

Results of access tests via a Linux laptop

==================================

LINUX MINT 19.3 (TRICIA)
 
PUTTY - Set up the configuration as follows:

Category: Terminal
- tick 'implicit CR in every LF'
- tick 'implicit LF in every CR'

NOTE:  This ensures that the returned text is correctly formatted.

Category: Connection/Serial
- Serial Line to connect to: /dev/ttyUSB0
- Speed: 115200
- Data: 8
- Stop: 1
- Parity: None
- Flow Control: None
 
Click on 'Category: Session'
Click on 'Serial', a radio button
In 'Saved Sessions' click on 'Default Settings'.
Click on 'Save'

 PUTTY METHOD#1
Open:  a Terminal window
Type:  'sudo chmod -R 777 /dev/ttyUSB0'
Enter: [password]
Type:  'sudo putty'
Select 'Open'
Enter: 'CTRL + m' then 'CTRL + j' to wake up the Zero MBB and display the '>'.
After each entry, ie, 'help', finish with 'CTRL + m' then 'CTRL + j' to make the MBB respond.

 PUTTY METHOD#2 - I forgot to try this one!
By default, PuTTY sends the Telnet New Line code when you press Return, instead of sending Control-M as it does in most other protocols. 
PuTTY emulates xterm which emulates vt100. To have putty send CR/LF when pressing enter, type ESC[20h in putty after connecting to the serial device. This sets VT100 LNM true.
 
 PUTTY METHOD#3
Sending CR+LF is possible in modified PuTTY. Source code is available at https://github.com/gniemirowski/putty-crlf and Windows binary at https://www.grzegorz.net/pliki/putty-crlf.zip When you run this version just go to Terminal -> Keyboard and select "CR LF" for "The Enter key" option.
 
===========================================
'CTRL + m'   CR  13 or 0D
'CTRL + j'  LF  10 or 0A
===========================================
COOLTERM

http://freeware.the-meiers.org/CoolTermLinux32Bit.zip

Open:  a Terminal window
Type:  'sudo chmod -R 777 /dev/ttyUSB0'
Enter: [password]
Run CoolTerm
- Speed: 115200
- Data: 8
- Stop: 1
- Parity: None
- Flow Control: None
Select Connect

===========================================
INSTALL PUTTY CR-LF

1.  Delete all the putty files from any previous install attempts on the laptop, if exist.
2.  sudo apt-get install build-essential libgtk-3-dev
3.  git clone https://github.com/gniemirowski/putty-crlf
cd putty-crlf
./mkauto.sh
./configure --disable-git-commit
make
4.  Run new putty-crlf:
cd putty-crlf
./putty

===========================================
CREATE BASH SCRIPT - serial.sh

path to serial.sh: /home/username/

touch /path/to/serial.sh
chmod a+x /path/to/script.sh
'mcedit /path/to/script.sh' and paste this code:

#!/bin/sh
echo logan | sudo -S chmod -R 777 /dev/ttyUSB0
/path/to/putty-crlf/putty

==========================================
TERMINAL
/home/username/serial.sh

LAUNCHER
/home/username/serial.sh
==========================================

I hope the above is of use to you.  Whatever method I use, I always have to enter ctrl+m and ctrl+j after each command to get the MBB to respond.  I don't know why.  I maybe a Linux thing.  I'm going to try the above using a windows 10 laptop.  I'll let you know how I get on.  Thanks to all of you for your help on this forum.

Cheers

Gary

Hi Ninja62,

The penny has just dropped.  I only selected 'Implicit LF in every CF'.  I forgot the 'Implicit CR in every LF'.  OK, back out to the bike now.

Hi All,

Using PuTTY and Mttty I can connect to the SR/F (at last!).  Herewith the process and the results I achieved:

1.  DO NOT key on the bike
2.  Plugin the USB connector into the laptop
3.  Plugin the OBDII connector into the SR/F
4.  Run up PuTTY
5.  Set 115200,8,n,1,N and hit connect

The cursor will just sit at the left hand edge of the PuTTY window
6.  Now enter Ctrl + m
7.  Now enter Ctrl + j

The SR/F will wake up and reply:
ZERO MBB>

8.  Type in 'help' (without the ' symbols)
9.  Now enter Ctrl + m
10. Now enter Ctrl + j

The SR/F will reply:
ZERO MBB> help

=====================================================================

As you can see, the information is there, it is just difficult to read.  The SR/F does not appear to send CR/LF's

Cleaning up the poor formatting give this:
