Hi
I park my beautiful Model S outside each day when I go to work in Austin. These days at 5:30 or 6PM the phone app often reports an internal temperature greater than 110 degrees F. I have seen 126 degrees F. I found the scary clip below on a site called "Battery University". It relates to lithium ion batteries. I wonder if it s really true that the hot Texas summer is damaging my battery and reducing its life by 50%???? Do I need to leave my Model S in an air conditioned garage and ride a bike to work?? That would surely damage me! Are there any electrochemists or battery buffs out there who can assuage my fears??
All batteries achieve optimum service life if used at 20°C (68°F) or slightly below. If, for example, a battery operates at 30°C (86°F) instead of a more moderate room temperature, the cycle life is reduced by 20 percent. At 40°C (104°F), the loss jumps to a whopping 40 percent, and if charged and discharged at 45°C (113°F), the cycle life is only half of what can be expected if used at 20°C (68°F).
