As for autonomous - well, maybe in urban areas. The tech bros who design these “social innovation developments” tend to lack diverse voices in the boardroom and are rather mono cultural in views. Just as a world designed by men for men is undesirable, so is a world designed by and for the tech bros! |

Have to agree with you on that TMW. Nailed it. |

Sounds potentially interesting, but beware of hype (note that journalists these days, in general, do not understand science or numbers). I can't read the whole article (paywall), but: "the first five-minute batteries will be made available for testing this year" says to me that this isn't yet a working commercial model. Beware the R&D valley of death. |

(note supercapacitors have been talked about as an alternative to batteries for a while - no one's yet come up with a working prototype).

The company involved seems to be StoreDot, here's their technology page for those that can understand these things store-dot.com FRom another article today that's not behind a paywall renewableenergymagazine.com "StoreDot’s XFC FlashBattery technology enables charging of EV batteries in minutes, rather than hours, achieved primarily by replacing graphite in the cell’s anode with metalloid nano-particles, such as silicon, to overcome major issues in safety, cycle life and cell swelling during the charging process." |

That's a pretty high power delivery required; some massive copper cables required to push (say) 20kWh in 5 minutes.

(^) Good point. Yes, by domestic standards. You're in the region of 30mm diameter.

The current rapid charge cables are weighty enough for the 150kw chargers etc. Nonetheless, I can see super rapid charging definitely being something which current ICE drivers feel is needed to push them over the edge to EVs. I've noticed so many more recently; perhaps it's the green flash on the number plates, or that I'm just on the lookout. Last Friday when I was picking up son #4 from scouts I was in a group of 4 cars, 3 of which were EVs of different flavours. |

Perhaps my quick calcs went wrong somewhere - but your #14377 example is a 240kW charger. So 1000A (or 600A on 3-phase). That's some decent cable. What is used in the 150kW capacity ones you see? I think you see them because you're looking (and know what to look for). I hardly see any - but I assume I'm wrong and I don't notice(*) (*) obvious exception for Teslas, and Nissan Leafs which just look ridiculous. |
