Impossible to tell. Drain the battery to turtle, then charge to 100% and measure energy from the wall. 24 kWh+ and you have a good battery.Boomer23 said:So do I have a crap battery pack, or what is the opinion of the brain trust?
For the pack to reach the overnight low, it would require active cooling or the car to spend a lot of time at the low temperature. There's just too much mass and insulation in the battery pack.KJD said:This was down from low 80's last night before parking the car, but not as low as I had hoped for. It seems that the low overnight temps do cool the pack some, but I have never seen pack temp as low as overnight low temp here.
As ed mentions, keeping the car in the coolest location possible will result in the lowest pack temperatures. If you can get your pack down to mid-upper 60s at the start of every day which keeps the pack in the 80s by the end of the day, you're not doing too bad.
Right now I'm now starting the day in the mid-upper 70s and finishing the day in the upper 70s. Previous summers put me in constant 6-bar temps so I imagine that meant upper 70s to 80s.
