Hi friend
I did simple bms (lead acid battery)
Problem that the charge level not showing nothing
Any suggestions what I did wrong
Thanks

Hi friend, i need help a little bit, Twizy driving fine but my charger sometimes randomly shutdown ... solution is to just unplug and plug again, but this force to babysit your car, is there any possible solution via code ? Someting like loop to start charging again if SOC below value ? Im not scripter or coder sadly.
SimpleBMS.zip

Hi all im im new in this and I have some questions about twizy battery first in /if I take a battery from other twizy will work? Second is were I find the code? Becouse I buy all the staff to build my self one Thanks you all sorry for my bad English

Hi, my twizy is stuck charging at max 5A, tried a lot off settings and a lot of BMS (Blazej BMS, KlausBMS, SimpleBMS). Unfortunely im still not so advanced in coding on Arduino, but i changed setChargeCurrent() value to 10 A min in code to make sure but no success. Charging percentage are not updated, i need to switch off->on. Any sugestions ?

Hello!
Thanks to your code we got super far with our twizy! most fault codes are gone, but some annoying ones stick.

The first one is like the title: Start signal Fault P0412.
Along that code we also got: Power supply relay Fault P0218. We got a relay connected to the Sevcon relay wires on the plug coming from the Twizy.
The red STOP light is on and and the battery logo with ! on it, no ERROR though.

For now we are just connecting the bare minimum to test if it still works but to no success yet.
I was wondering if you might know a fox for this issue?

Hope to hear from you soon!
Greetings Kenneth

Hi a little question is possible that the chargers won't work on difrent twizys ?I mean if I take a new charger will work on my twizy? Because I u buy a new one and it doesn't work

Source: https://github.com/dexterbg/Twizy-Virtual-BMS/blob/master/extras/SEVCON-Configuration.md

I tried doing this via Ovms, no success still cutsoff after 39 V

Patient:
Twizy, 2012 ,custom 8.7 kwh battery,

What i tried already:
Setting Twizy same as for applying tuning (no switching to GO)
In shell:

1. enable
2. xrt cfg pre
3. xrt cfg write 2c02 01 592
4. xrt cfg write 2c02 02 560
5. says --> OK, value edited is same as we set
6. xrt cfg op
7. But still cutsoff, with STOP light and SEVCON low voltage error

Tried also standalone
xrt cfg write 2c02 01 592
xrt cfg write 2c02 02 560
but no clue how to get this to work

Blazej has reworked a handfull Twizys using the VirtualBMS and has found an issue: the current VirtualBMS implementation does only work with chargers up to generation 5 (charger label: "Ind …"). Generation 8 and newer do not work, generations 6 & 7 have not yet been tested.

The effect is the charger being stuck in the first protocol init step (F0-A2 in 597h) for both driving and charging. We've found no differences yet on the CAN side. We also tried some variations on the 3MW timing, but without success.

Please reply if you can share some insight or information on this problem or can help solving this issue.

Hi, i found a problem with new charger lnd14? 2018 year, problem with "enterstate Init" and "enterstate off" in old charger you see on frame id423[0] and see does first bit changing 03h to 00h but new charger all time send a 03h so after switching twizy off bms still think that twizy still turned on because state in debug - "driving"

After using Twizy for 1.5 year and doing 19 500 km, i did improved Arduino project still based on SimpleBMS, with very precise voltage meter (0.03 voltage accuracy), because used way is way to unprecise to use (0.3-1v accuracy) based on voltage delivered to Arduino and temperature. I expanded project with multiple security option like 3 temperature sensors, various temperature alerts and limitations, with use of ads1115 to have precise voltage based on project: https://www.youtube.com/watch?v=10QtHh6UNBs, merged toggeder. I want send you soon my project to use :)

I want to ask you, did its possible to control range showed in Twizy by battery ?! If yes tell me how pls :D
