You have been quietly working on this for some time, excellent workAtkam wrote:Hi,
I not calculating internal resistance, and min max C before start a project but just setup a battery 96S22p and working fine.
(internal resistance is lower in main battery then additional battery - this is simplify a lot of think)

Great news and congratulations! I'm not in the EU but I am interested in the whole concept and will be following your progress in the future. Best of luck with the endeavor and business. My 2017 Leaf will fulfill my needs for as long as I can imagine but I'm an EE and looking at retirement in a few years so I will need some sort of projects to keep myself busy. Your work is encouraging, exciting and is one of the few parts of MNL that is most useful and interesting to me. Thanks!mux wrote:Alright, for the EU people who want an extender battery and don't mind giving up some trunk space, I've now just cleared all the major hurdles to commercialize my extender battery and offer something decently professional and not-immediately-explody. I'm gauging interest with preorders on this website:
If all goes well (and that is a big if, there is still lots to do) I'll be converting cars in Q4 2018. When all the kinks are worked out, I'll also try to sell the electronics, possibly the batteries (not quite sure yet) and have tutorials on how to mod your own car for non-EU people.
This is what really sucks, historically this practice was all but impossible and it kept used cars cheap with plentiful parts.EVDRIVER wrote: LEAFs also don't end up being scrapped they in many cases go to auction and are shipped in very large numbers to Russia, Ukraine, the EU, etc. The export numbers are incredibly high for used LEAFs, one single private party alone ships many thousands of cars yearly.
My understanding was that 18650 are rated for discharge at -25C.mux wrote: It really depends on where you draw the line. Want to keep the battery in tip-top shape? Blanket, PTC heater, pretty high temperatures. Want to just barely scrape by? Probably keep it insulated or in a garage at more than the rated minimum temperature (which is -25C in this case).
