“BYD confirms new 1,000V ‘Super E-Platform’ capable of fast charging 400km in 5 minutes” (electrek):
Chinese auto conglomerate BYD has introduced a new 1,000-volt EV platform that can enable charging rates as fast (or perhaps faster) than a trip to the gas station. We’re talking five minutes. … offers 1,000V and charge rates up to 1,000 kW.
How can this be made safe? If everything is new and everything functions as designed, the car and the charger communicate before the cable is fully energized. A GFCI will trip if a portion of the 1000 amps starts leaking out to ground (via the human holding it?).
Let’s assume that there aren’t any mostly peaceful Massachusetts climate change warriors to vandalize the charging station:
Both car and charger still face the relentless enemies of time and corrosion. GFCI outlets in home situations are known to fail after 10-20 years. Consumers aren’t going to wear heavy rubber gloves the way that trained utility workers do. How long will it be before the foolproof failsafe systems fail either due to unforeseen foolishness or age/corrosion? That leaves the EV owner (wearing a MAGA hat since Democrat climate change alarmists have gone back to pavement-melting SUVs?) with his/her/zir/their hands on a failed cable carrying enough power to run 800 houses.
Maybe the argument is that people will be killed by these 1000V charging systems as they age and get maintained by the same Americans who can’t make public WiFi work, but it won’t be a higher number than are killed in freak gasoline fight accidents.
Loosely related… a carefully engineered high-voltage power system with full redundancy (CNN) …
Even more loosely related…
Here’s ChatGPT’s response to “Create an image of a nonbinary Tesla owner next to his/her/zir/their car” with the refinement prompt “The shirt should more clearly indicate that the person identifies as a member of the 2SLGBTQQIA+ community”:
Grok seems to think that “nonbinary” is the same as “nonwhite”:
I asked ChatGPT “Redo the above image to look like a hand-drawn pen and ink sketch.” For some reason, it made a lot of other changes as well, including mirroring the orientation.
I wonder if someone could get an A in an online art class via the use of ChatGPT (the failure to spell “2SLGBTQQIA+” could be considered artistic license).
Instead of “Redo the above image to look like a hand-drawn pen and ink sketch.” why can’t chatgpt just take a single word like “outline(“image.jpg”)” Either prompt is equally painful to look up.
How can this be made safe? We can put a warning label similar to California prop 65!
NJ says it is not safe for consumers to pump their own gas.
My City has installed four ChargePoint Level-II EV chargers (cost is $4400 before installation). They function very well, but the FL sun kills the user interface screen after two years.
Imagine the explosive potential of lithium exposed to water. Funny how we went from an automobile being started up by muscle power to a start up that requires tesla par trois and that’s considered progress. Used to be that you could buy a mare and she ran on hay and she was self-maintaining, self-fueling and could reproduce with a successful “stud-mount”. The blood could be carefully used to sustain the rider’s life without hurting the horse and the mongols conquered most of eurasia using them — including china.
@Mememe there are so many things wrong with your comment that I was going to reply but gave up. You deserve politicians like Mike Waltz and Pete Hegseth.
Let’s not forget about the manure that used to cover the streets in the “good old days.”

Phil, where is your entrepreneurial spirit? You should see these deep insights as opportunities!

I don’t remember people expressing concern when handling about 20 MW worth of diesel at petrol stations (30L/min at 39 MK/L). This is much safer than refuelling at a typical petrol station (which, by the way, can also be burned to the ground). Unlike with diesel or petrol, where a customer can actually spray the liquid all over, the electricity in EV charging stations is protected by multiple safety layers. First, you won’t get any near any live leads as the entire connections are protected by multiple layers of safety, insulation, and plastic. There are also several RCDs that will stop the flow in case of any Earth leakage or otherwise. Plus, the cables are much much thicker and insulated than they would need to be otherwise. An IEC 60309-4 is much lighter and thinner but can still handle 0.8 MW.
If you actually look at an EV fast charging connection, you’ll see many cables. There is a lot of negotiation between the car and the station before any DC current starts going. The car actually sets the charging power, controlled by temperature and battery capacity. In most cases, the peak value (here mentioned as 1 MW) is only achievable for a short period when the battery has a low charge. Most of the time, it charges at much lower power, especially as batteries near 80% charge.
