I decided to try to set my Roadster so that it starts charging late at night rather than as soon as I get home, with the thought that that way it won't be sitting around at a full standard-mode charge all night. The idea wasn't to try to get it to a partial charge, just to have it start later.
I've never used timed charging mode before, so maybe I did something wrong. I got home, parked the car and set it to start charging at 4AM. I plugged it in and it started charging immediately. I got back into the car and again set it to charge at 4AM. It stopped charging and put up a note saying "scheduled charging at 4AM" or something like that.
This morning, I got to the car and it hadn't charged. It had a screen that said "plug in cable" or something, even though it was plugged in. I switched it to "charge on plug-in" and it started charging, but it only added 2 ideal miles in the time it took me to take the garbage to the curb.
Luckily, I have enough charge to get me through the day, so it's no big deal. Still, it's annoying.
Has anyone else had problems like this? Any suggestions?
This is a bug in the firmware. If the car is already plugged in when you are messing with that timing setting, it doesn't always notice that you have set it to start charging at a certain time.
Opening the charging port door (and plugging in) after this has been set seems to be the key to the car noticing your settings.
I was in a showroom last week and the current ESTIMATE for a battery replacement is somewhere between $30,000-$40,000. Is this correct? Also, if the battery is reduced in capacity by 60-65%, at least it is still functioning which is not what I was led to believe is the case after 100,000 miles.I sent some questions to Tesla Motors asking about strategies for extending the life of my battery pack. I was looking for more tips beyond just plugging in and recharging to standard mode each day.
I received a very detailed response from Dan Myggen and he gave me permission to post it here.

If I understood the battery warranty correctly, it does not guaranty a replacement, only a warranty against being defective from year three on to 100,000 miles or 7 years. And I was mistaken in that the battery life is reduced to 60-65% not by as pointed out by tennis trs.You could lock your battery replacement cost at $12,000 by purchasing the option from Tesla. In reality, the cost will likely drop within 5 years and the real cost will be lower. Or the battery you get in 5 years may actually provide 400-500 miles of range. The technology and the pricing is improving every year.
Most people would be fine with 120 ideal miles of range in standard mode. I know that I am fine with that most days. Within 5 years we will have more recharging options out in the wild.

What locality requires this ? And how much is that additional expense going to run ?If applicable law requires Tesla to return a replaced battery to you, you agree to pay Tesla the additional cost of the replaced battery.
Interesting, I wonder if this was perhaps due to the high cost of cobalt. Be it as it may, I wanted to direct your attention to Tom Moloughney's blog. Tom is one of the MINI-E pioneers and he posted a very thoughtful comment on the plugincars.com article about battery care a fellow Leaf owner wrote couple of months ago.The LiCo cells that Tesla uses have the highest recycling value at this point of any of the Li chemistries.
Basically. The lithium isn't worth recovering at this point as far as I know, nor is the aluminum, which are sold as slag, but the copper and cobalt are. (To be clear the lithium and aluminum are not disposed of, they are just not extracted from the slag as distinct elements. The slag does have industrial uses.)Interesting, I wonder if this was perhaps due to the high cost of cobalt.
Agree. If you just follow the standard recommendations I think you'll do better than expected anyway in most cases.How is this relevant to this thread? If Tesla recommends to routinely charge the car in standard mode, they will base their battery life estimates on that. They will likely be conservative, which means that there is a good chance that we will see better results in the real-world. And if you treat the pack conservatively, you could improve upon that further. The question is then, do you really need to do that or would you be satisfied with the longevity you are getting by following the standard charging protocol.
