Re: Eltek/Volvo charger

Hi tom91. Well, you have very quickly exposed my knowledge gaps. I presumed that one would simply tell the charger what voltage to pump out (which would be equivalent to 100% SOC) and then leave it be, since the actual amps coming out are quite small relative to the C rate of the battery.
Because of this assumption, I have deferred the BMS decision until I have decided what my battery will be later on in my build. For now it's all going to run on the bench with a little, unprotected 1kwh / 250v / 3C pack I built.
It sounds like that is a bad thing to do, and that I should be integrating the Eltek charger with a BMS and/or something to manage the state signals.
I actually just created a classifieds listing requesting some guidance on this subject. If you are happy to give me a bit more of an in depth perspective on this, I'd happily pay for your time.
It feels like there is a bit of a gap in Noob info on this part of EV conversions, so I'd be happy to write something up as I learn more as well.
