As an aside, the guys who ran the test are pretty cool. I especially commend them for letting the owner know what they would be doing with her car.

Prediction: Battery is fine. Firmware update will fix (corner case?) issue where car won't charge.

As an aside, I suspect the issue of their only getting 66KWh usable is likely attributed in large part to other vehicle overhead. With a 32 hour stint, a draw of 250W works out to another 8kWh used...

So, the person writing the article is wrong. The OP should have stated that you have to follow some huge tweet storm to get the whole story. The article repeatedly states that they are the owners.

U mad bro?

Nope. The kWh consumed and the consumption rate (wh/mile) includes the energy to move the car and the auxiliary power like AC and heating.
Ah, you are right. Ignore me... I was thinking it of the overall vampire drain which can be in that ballpark, but that's while the car is not in drive.

Thanks for the correction.

Discharging an EV to 0% can be dangerous. And with not accepting a charge, I guess vampire drain will make it even worse right now.

Driving a rented EV to 0% is like filling a rented gas car with diesel, you just don't do it.
That's why Tesla maintains an "anti-bricking buffer" where the state of charge when the reported range is zero is still safe for the battery.

And on the model S, there's a second level of reducing power-consumption to avoid damaging a battery due to vampire drain, I assume the Model 3 would implement similar.

I’ll just leave this here for you.

Incidentally, hope you’re having a great day.

A much as I loved following this quest, the main stream media has now picked up on the unfortunate aftermath, and it is another bad news story for Tesla. Its a shame they couldn't have opened the SC right away to get this sorted and avoided the bad press.
