looks like there is a capacitor inside the curtis. The day after i drive in the car and voltage back to normal, so alll works fine now

Hi, i desided to but the fix from You. My arduino fix Works fine, but after a charge to 75% i needed the car for a shirt trip, and now the curtis voltage show 8-10 volt more than the voltage on the batteries. So now at 93 volt on batteries, curtis meter show something like 80%. Is there some way to ...

oki, you might be right ;) I made a schematic and beta print arduino shield layout today http://techmind.dk/citroen-c1-evie-elbil/modifikationer/zivan-ng3-citroen-c1-bms-hack/ for the hack, and will make a pcb next week. But, i think i should buy the zivzn reprogram kit from you. What is the multitu...

Hey, great ;) Yesterday i made an experiment, i simply removed the connector from BMS to zivan at 93volt, the connector is nammed 'zivan on/off'. If the BMS still runs, then i seems very easy to let a arduino sense charge voltage and disable 'zivan on/off. Is there any problems in this hack? The bdi...

Grumpy-b : i am interestet in the zivan conversion You wrote about, including guide and parts needed, michael

If the zivan charger is changed to stand alone, a buzzer could be connected to the cutoff pin from the BMS, or af flashing led.

Would be great to remove the 25 % Low speed function, ør change it to 10 % if possible?

Hi sounds like a posible fix ;) also i trust the zivan charger algoritme more than the BMS. So as i understand This the zivan stop at 93 volt and bms continue to balance cell after this? Do You have any idee about how many miles this lower charge will affect the max distance for the car? After this ...

Hi, As i know the battery charge end state is to high, and might be the reason why cells die because tundersky changed spec for the TS-LFP160AHA lifepo4 cells: http://translate.google.com/translate?sl=da&tl=en&js=n&prev=_t&hl=da&ie=UTF-8&u=http%3A%2F%2Ftechmind.dk%2Fcitroen-c...

Kettner is closed and also the Company they made the c1 evie fore: chooseev.dk, clever.dk has tanken over some of the people involved in c1 evie

Hi, looks great do You have a website With some info about the data format from the bms serial adaptor? I would line to make something like You have , i planned to use arduino to proces data, what kind of controller are You using ?
