Truth!
Not sure how ICE vehicles with a higher output alternator handle this as they to could have the same potential......
Car manufactors never take out much higher A then the batteries can handle, using thinner cables from alternator in order to make the A low. You never se more then what the batteries can handle. In my case on my RV with 150A alternator, around 30A since I have two 100Ah lead acid start batteries. Infact, one of the things I am doing most on work, is to sell and install DCDC in order to juice up the RV batteribanks for custumers. And of course sell the LiFePO4 batteries. I have a 90A DCDC in my RV, feeding 600Ah LiFePO4.
I guess the Koreans(not sure if anyone other than Kia and Hyundai) could be onto something by dedicating a portion of the main Li traction battery to 12v and not having a separate 12v battery......in one way I'm not sure I'd like that as you can't really replace it but maybe it would never need replacing, well as long as the main traction battery stays good......not positive sharing of the main battery for 12v is still done but I now it has been done in the past.
This is interesting. I think they are into something good here.
Stanton said:So are you trying to say that (EV) owners should replace their 12v lead-acid batteries with 12v Lithium? I completely agree (see sig)! Most folks just don't want to spend the $$...but after almost 9 years I think I've "got my money back".BluetoothMonster said:Lead acid hates that when it comes so rapidly, violently and high numbers, lithium loves it.
I think you have been clever!
Nubo said:I think you are drawing erroneous conclusions based upon your tests with a Lithium battery.
And on the other 21 pages here there are not any errouneous conclusions? :roll:
All I can say is that this works now. Did not before. I would love if someone with the same year model could measure the A draw when charged like I have described.
Of course we need more input on this before its valid, but I find it very strange if the software for some reason suddenly should go into this behave, doing like it does now. We know for sure that Leaf have a 12V batterproblem now, very many of the earlier statements about this in the start is clearly wrong.
It seems for me that the voltage has been the big issue here in this discussion, and not A that blows internally this small lead acid batteries.
This thread need a new angle on things, and you are not coming with any useful information right now.
