No pictures, ’cause I had to head to work quickly…
Step two of the Range Test Days and Tesla Roadster pack rebalancing that I was doing was to get to my first daily “standard” charge to see if it made a difference.
Following Michael Thwaite’s suggestion to maintain the charge (and not drain too low) we plugged in the Roadster on Saturday night with about 102 Ideal Miles on Storage mode.
On Sunday, drove the car out for some further errands, etc. and ended up home with 21% SOC/37 Ideal Miles/34 Rated Miles left (thanks to OVMS again).
This time, I plugged it in and performed a STANDARD charge starting at midnight… (a few hours earlier than I normally set the car to charge. To maximize the amount of 40A/240V charging that I will do at super-off-peak EV rates.
When I rolled out at 9am, the car had 174 Ideal Miles on it and the CAC values were at 145.44. It was a slight improvement to the 171 Ideal Miles that I observed last week, but definitely nothing to write home about.
I guess we’ll have to see if we can change my better half’s behavior and see if she can plug it in every other day so that we can drain the battery down 120 miles in two days of driving vs. the 60 miles a day that she normally charges under to see if that will do something to improve the CAC values and ideal miles after a full charge.
I cross posted questions on these tests to teslamotors.com, so wanted to put the CAC values here –
Values from October 2013, when I first started to use OVMS.
Standard – Charging Done SOC: 96% Ideal Range: 183 mi Est. Range: 173 mi ODO: 3,578.8 mi CAC: 154.38
Values from today overnight charged in Standard mode and 174 miles (the CAC value is the same from the evening before it started to charge.) (unfortunately after my wife drove about 30 miles)
Not charging SOC: 82% Ideal Range: 147 mi Est. Range: 144 mi ODO: 10,901.2 mi CAC: 145.44.
One thought on “First Daily “Standard” charge after the weekend’s Range charge test”
