Porsche and Audi issued recalls for more than 130,000 battery-electric and plug-in hybrid vehicles to address two unrelated fire risks. The larger of the two campaigns is actually directed not at the cars themselves, but at the charging cables that were sold with them. This recall covers all vehicles sold with the company's 40-amp, 220/240V "industrial" charging cable designed to fit a NEMA 14-50 outlet. Parent company Volkswagen says Porsche and Audi were made aware of instances where the cable could overheat due to a poor-quality, outdated or defective home electrical setup, potentially leading to a house fire.
VW said the issue was discovered because over time, an overheating wall socket can damage the charging cable itself, leading to increased electrical resistance in the wiring. When those same charging cables are later used at public charging stations, the higher temperatures resulting from the increased resistance can trigger fault codes in the chargers, potentially leaving motorists stranded. The company said a similar fault at home without the redundancies of a public charging station could lead to equipment damage and even fire. Because the recalled units are merely charging cables and not hard-wired boxes, they have only basic safeguards against misuse. The recalled cables will be replaced by new units with more robust thermal overload protection.

The problem is there are no standards. Running 50 or 60 amps for hours will create heat. Your average 220 plug will melt.
This is completely retarded.

So it's not the cable, it's your home electric setup that causes the problem. Easy peasy - just re-wire your entire house before you bring home your EV and no worries.
The entire economy will benefit from this expansion, and let's hope that all of the illegals pouring across our southern border are skilled, trained electricians.

Current always heats conductors. I don't think many home owners have a clue what it takes to conduct 50 amps for an hour. Fuses and connectors cost in the thousands of dollars for long term reliability not to mention the labor to set it up.
Service to the average home will need to double for a big EV.
They wanted to be like Tesla and burn your house down
UL testing standards generally far exceed rated capacity and operating conditions. It said the faults were attributed to faulty home wiring. I wonder how much of that was DIY without inspection? I saw some moron on youTube suggesting a way to install a 220 outlet for charging by wiring across two 120 VAC branch circuits. (This will only work if the branches are antiphase.) It was apparent that this idiot had no idea what he was talking about, and reflected the worse of shade tree mechanics attitudes, and workmanship.
I posted a reply on youTube about my concerns, including the necessity of being antiphase, but more generally about the dangers of this kind of slipshod electrical work. He replied with what I took to be an ungracious “It works, doesn’t it?”
Until the house burns down.
LMAO
If these companies can’t avoid fire risk with 12 volt systems, I don’t want what they build for 240 volts.
LOL !
Another thing on video I posted about before: The cherry on the top of the cake was he was recommending this installation for people using Toyota 120 VAC chargers to supply the charger with 240 VAC through a NEMA 120 socket. Utter insanity. When he burns his house down, he’ll sue Toyota.
Lego is amazing!
Oversize electric golf cart fanbois hardest hit.
Maybe they will post a pic of their goofy looking hot wheels thing.
The issue is nobody at home has any appliance that can draw 50 or 60 amps for extended periods. There’s no historical data to draw from except in factories and shops. They are just guessing. The time is the root problem here.
Running for jours lets heat build up, melts components and resistance just goes up from there but the current still flows.
Those plugs and outlets are made for dryers and ranges. They both use lots of juice but not for long at a time. The constant draw needed to charge a giant battery will create a lot of heat over a couple of hours. Bogus setup.

Hunter’s Porsche just snorts right up.
