> Many of those who think their cars won’t charge are new to EVs and don’t know how to “precondition” their batteries, said Westlake, who has two Teslas.

I am a bit confused what’s that supposed to mean, because there is nothing a driver can do to “precondition” the battery manually. When you select a charging station on the navigation system, the car automatically displays a “preconditioning the battery for charging” notification once you start your route and starts preheating, and that’s it. I honestly cannot think of a way to make it more intuitive and uninvolved on the driver’s end.

And if you attempt to charge it without preconditioning (which would happen if you drove to the charging station without using the navigation system), the car would display a large warning once you start charging, saying something like “hey, next time navigate to the charging station using the nav system, so that the battery is warmed up and preconditioned”.

Outside of edge cases (like super cold temps that are outside of what almost anyone in the US will ever experience), preconditioning isn’t really necessary, it is just for faster and more efficient charging.
