I've been at 5 bars almost the entire time I've had my Leaf. I've seen 6 bars after a QC, and sometimes in the afternoons on the drive home.
This morning it was 21 C in the garage, and I've seen 6 bars in the morning for the first time. Heat wave (near 90 F!) is going to last through today, might see this again tomorrow morning.
If 10C warmer for a day removes a day of life from the battery pack, then reducing the temperature in the garage by 5C in the summer is worth money, even in a cooler location. Consider the following:
Assume price of battery pack replacement = US$10,000
Assume life at current conditions = 8 years.
Assume summer is 4 months, and by putting a fan and or vents in the garage the average temperature of the garage in the summer is 5C lower.
Assume the car is in the garage 2/3 of the time.
Extra life would be life / fraction of time cooler /extra life fraction /time in garage = 0.67 years
Value of extra is roughly Price/life*extra life = $830.
This is a very rough calculation. YMMV SDD SRA.
