Here is an interesting insight to the 12V AGM battery. Vehicle is a 2013 Model S, 85kwh.
This is for sharing purposes only. I love my Tesla, it makes me smile every time I drive it. I have PW2, am inline for a solar roof and a Cyber truck.
The battery is brand new, Tesla Mobile Service was great. Afterward, I installed a cheap Bluetooth battery monitor which displays history on the phone.
(Auto Battery Monitor BM2) from amazon. Installing it is a small challenge with frunk disassembly and tight quarters at the battery.
This plot is over the past 15 days. You can see that the 12V battery discharged and recharged, 32 times in these 15 days. That is a bit more than twice a day. The car was driven and or charged where the lines are squiggly (I did not keep good records).
It is easy to see why the 12V battery is short lived with this many cycles per day.
Charge begins at 12.53V, ends at 13.79V and there are short spikes at the end of charge of about 15.3V.
I may put a trickle charger on the Model S to reduce the number of charge cycles. I do this on my ICE cars as they rarely get driven.
Just thought it was interesting enough to share...Enjoy...
