    Hi All.

    I was wondering how the Teslas' battery charge holds up in hot weather. In Sacramento, it can get to tripple digits in the summer and even when it gets to the high 90s, my hybrid battery looses its charge when I park in the sun. I often have to wait until the car regenerates the battery when that happens, in order for me to get the acceleration boost from the hybrid battery.

    Does the Tesla have any problems battery charge in hot weather?

    I assume your hybrid's battery is not cooled, or if air-cooled then only with ambient air. The liquid cooling in the Tesla makes all the difference, and this should not happen, except that the cooling system does take a little energy out of the battery pack while sitting in the hot weather.
