That's because it has a larger battery and thus can charge quicker. On top of that while you may have all 12 bars that doesn't mean your HX value hasn't dropped from 100% so you are trying to compare a car with a higher HX value and a bigger battery to support your claim that the charging profile has changed which is clearly absurd.

Generally accurate.

I am 72 days experience on a 2011 replacement with the new 'lizard' chemistry battery.

Still at 100% SOH.

But Hx finally dropped slightly below 100% yesterday.


I've seen Hx on my new battery vary quite a bit both above and below 100%.

The correlating factor seems to be battery temperature. Logically one would expect a colder battery to have higher resistance. That seems to be true enough judging by the recent temperature swings and by the Hx value.

All of this to say that you may see Hx go up again, maybe back to 100% or more in the spring once battery temps revive. Of course once we go through a the 2017 summer we can expect to kiss 100% Hx goodbye forever :-(


not true... in theory. Li has a sweet spot for temperature just like we do. IOW; there is too hot and there is too cold. You can maintain high Hx with battery temperature management. now how to do this is the real question. If faced with fun Sun parking in the front row or back row parking with shade? well, that is up to you...

That might be a reasonable approach in the PNW, in Tennessee 99 in the shade is 99 in the shade.

At least I can keep the car garaged most of the time now my employer has moved us into a new building. I park in the basement at work now :-)

that does not change the fact that 99 in the shade is 120 on the asphalt
