My understanding is that it does not charge all the way. There are some advantages in having a s/w locked down battery rather than a physically limited battery. Since the battery charges slower when it is above 80% capacity, you can recharge to "100%" much faster with a software limited battery. Similarly, charging to 100% is supposed to cause more battery wear, so in a real 75 you don't want to do that very often. But in a 60, its no problem, since 100% is really 80% of the physical capacity.

My understanding is that it does not charge all the way. So doesnt that make this update a little late and kind of useless? The evacuation order was days ago. People have already left their homes--where they would have charged their cars. They already made it to where they were going on the 60kw charge they had or they didn't. The hurricane has already reached FL. http://media.miamiherald.com/static/testdir/weather/storm-radar-11-lg.gif http://media.miamiherald.com/static/testdir/weather/storm-ra...

  hah just replied with exactly the same thing. I'd say it was a PR move, but advertising that they lock down features doesn't strike me as wise.. but then again, I'm not an ad man.

    Good on Tesla for doing what's good for these specific customers than worry about their corporate image. If they continue to act on the users' behalf these events which may tarnish other companies will have no negative impact.

  The evacuation orders were only for low level areas. Half of the state is pretty much out of harms way and could make a run for it at this point, if they choose.

interesting. In that case, I wonder how useful this update is, since it would presumably just allow the consumers to charge their cars for a longer period of time, but they should probably be getting the hell out of the storm path instead.

I wonder if you could get around it with a relay and some resistors to trick the system into thinking the charge is lower than it actually is

  That's a good way to get a lithium fire. Lithium batteries need careful monitoring to charge correctly. To give you an idea, 4.2V is 80% charged for a chemistry I worked with. 100% is 4.23V, so you don't have much margin for error.

  You can get around it by placing your car in trip mode- which allows for a higher charging capacity
