Tesla updated its online design study for the Model S and Model X, showing precisely that newly ordered cars can be overloaded up to 250 kW.
The previous maximum value for the “Raven” version was 200 kW, and more recently 225 kW, while the Model 3 / Model Y was able to obtain up to 250 kW. S / X flagships now match the youngest duo.
Elon Musk confirmed the news and explained that increasing the maximum output power to 250 kW required thicker cables:
“We had to increase some wire thickness in S / X to reduce the resistive heating. Technically, it won’t be a 1000 mph load, since X is especially much larger than 3.”
However, we do not know if the change in wire thickness is the only change applied to reach 250 kW.
It’s also unclear, as exactly when the new S / X got the new hardware upgrade to load at 250 kW. There may already be Tesla S / X users who can charge up to 250 kW.
Finally, even though the maximum charge power increases to 250 kW, we don’t know how much the effective boost rate can improve. It may be noticeable with a low state of charge, but without testing, we can’t say whether drivers will be able to get back on the road in a few minutes faster or not.
