Agreed, but if nothing else, they could trickle charge that battery when they car is off whenever the voltage drops below a limit likely in the 12 - 12.5VDC range. If it reads above that limit but drops below it when someone puts a load on it by say unlocking the car (meaning there's a likelihood of a bad cell or other battery failure) then, the inverter kicks on and supplies the required voltage.techno-ag said:Or they could, you know, have physically linked door handles instead of electric ones.aggieforester05 said:Using a transformer or inverter that is already pulling from a massive 300-400 volt battery that gives them near endless 12 VDC on tap without the need for a separate battery. Seems like poor engineering to me. If it's a power consumption issue caused by the inverter, it seems like they could easily engineer around that. The fact that the car bricks when that little 12 VDC battery dies is insane and a huge safety issue as evidenced by this article. Even if there is a work around, it is clearly known by few people.Kansas Kid said:aggieforester05 said:
So they have a 12 volt battery to power the electronics like an ICE car in a car sitting on a gigantic battery pack? LOL...Somebody should tell Tesla engineers about transformers and inverters. Seriously WTF?
How do you think they charge the 12 volt???? Remember there is no alternator in the car. You get one guess.
I say the same about the idiotic 10 minute idle limit on my Silverado. It will turn off while idling in the summer heat. If someone were to leave their child or animal inside (rightly or wrongly, not here to debate that) they could bake to death over some idiotic emissions control limitation.
I'm really surprised this is an issue on a Tesla and makes me wonder if there isn't some other system failure besides the bad battery.
