Re: Is my battery dying ?

Dear DBMandrake, Thanks very much for your informtive replies and so honest comments, even I am sorry to note. I am sorry for your enforce and time spent. I am surprise to read the result of your swaping cells experience. On the other hand, surely you have accumulated a lot of knowledge that is a ve...

Re: Is my battery dying ?

Thank you very much JoeS for the cell numbering.
I think to swap my weak cells in spring-summer when the temp condition is more favorable and when the other 2 friends of mine will be available.

I will try to add photos following the procudurs in that link.


All the best you too!
Ciao

Re: Is my battery dying ?

Hello DBMandrake and hello to all others in this very interesting forum, My name is Sandro from Milan, Italy. Sorry for my poor English. I own a C zero and I have 2 friends with C zero too. My second hand C zero of 2011, has only around 24000 km, 14k of them driven by me since I bought it in Oct 201...

Re: I would like to set the charge current lower than 5A

Dear all, Thanks for your inputs. I have used a 220 / 110 trafo 1500VA rated and it works! Thanks very much. Supplying the EVSE at 110V the min current is around 3A on the primary side 220V that means some 700W. So I can start charging at 700W when I use 110V trafo tat is good for me as my PV instal...

Re: I would like to set the charge current lower than 5A

Thank you Don.
I will check with a trafo 230V / 110 V and let all of you know the results.

Re: I would like to set the charge current lower than 5A

It may not be possible to reduce the pulse width any further; it requires a 5% duty cycle for the EV-ECU/OBC to detect that an EVSE is connected and available. In another thread is a diagram: http://myimiev.com/forum/viewtopic.php?f=24&t=1497&start=110#p32608 I remeber I have seen the pulse...

Re: I would like to set the charge current lower than 5A

Maybe 230V to 110V transformer could help? Probably you are right. I will look for a scrap transformer with min 1kVA for some tests. Thanks for the tip! However I would like to see if changing the duty cyle signal of the EWSE PWM can force the OBD to charge with lower current. Maybe some of you in ...

Re: I would like to set the charge current lower than 5A

Hi there ! The charger will just not run at such low amps and it is very inefficient. There is a 600w overhead during charging, this is from running the electronics, voltage conversion, water cooling pump, monitoring and balancing inside the battery, etc. That means at 240v approx 2.5A is used by t...
