Interesting, I didn't know the charging cable was the limiting factor. Wouldn't the battery itself have any adverse effects, overheat etc?
TBH, it kind of freaks me out to handle even just the 50 kW cables.
From the article:
"Ultimately, charge times will be dependent on the power output ratings of the power supply and charging cable, and the power input rating of the EV’s battery. To obtain a sub-five minute charge, all three components will need to be rated to 2,500 amperes."
I wonder if anyone has been killed yet by a malfunctioning charging cable.
you don't need to start out full blast with electric cables. ramp up over a minute if necessary. we are also well versed in circuit breakers, and digital safety checks.
oh the cable isn't correctly connected? no power.
In this case, the "power strip" is passing 50kw and needs active cooling.
50kw would take 2 hours on a 100kwh pack so it would only be 0.5C. To do it in 5 minutes would require 1.2 megawatts of charge rate.
