All home charging is essentially trickle charging for a lithium-ion EV battery. Unless you have your own Supercharger (fast DC charger). No one does. The article made it clear the problem happens at "up to" 7.5 kW of charge power. So that would be 240V @ 32 amps or the maximum amount Porsche's US market mobile connector can deliver.
This was a mind-blowing revelation that Alex Voigt has delivered today. Not because I want to rub Porsche's nose in it but because the charges against Porsche rise to the level of consumer fraud. They are *very* serious charges. I just hope Alex hasn't been set up by the German auto industry (who would probably love for him to go away) to take a fall. If the charges are false and the 'whistle-blower' managed to convince Alex he was a real source when he was in fact a plant by someone covertly hired by someone in VW Group, it could cause quite a lawsuit. But Alex seems confident the whistle-blower is real. I just hope he's right.
With that out of the way, assuming the source is genuine and also knows what he's talking about, the revelation is really damaging for Porsche and it helps highlight what it means for Tesla to have a lead in batteries. For years Tesla naysayers have said Tesla has no lead in batteries and they always based this on the fact that Tesla did not manufacture their own cells. But, of course, they manufactured their own battery packs for over a decade and, perhaps more importantly, the software that runs the battery management systems. Now, of course, they make some of their own cells as well and that activity is set to explode in volume shortly. But this story highlights what happens when an ICE maker decides they have expertise in battery management because, how hard can it be? Red wire goes to "positive" and black wire goes to "negative", right?
@avoigt , good job on the major story! I would be interested to hear what kind of fall-out follows.
