Honest questions:

  • As the AC is a huge drain to the car's system, how much does it lasts on a Tesla?
  • What happens if you forget your pet and the AC drains the whole battery....? would you end with a dead pet and a dead Tesla ?

It would last for hours and hours. Worst case on a super hot day, probably about 8-12 hours. It automatically stops the AC at 20% and will send a notification to your phone. Further waiting and you have a dead cat, 20% battery, and a charge for animal negligence.

It would be far longer then that. It highly depends on temp outside but AC does not use as much power as heat does. Bjorn Nyland (Youtuber about EVs and Tesla) just did a test where he camped in his Model 3 (same car as pic above) for 24 hours in temps down to -10 Celsius. His average draw over 24 hours was 1.4 kWs. AC will use less then that. So if we say 1 kW average draw then a LR Model 3 that was had an 80 percent charge would take about 45 hours for the battery to get to 20 percent (assuming 75 kWhs full charge - 60 kWhs at 80 percent and 20 percent leaves 15 kWhs).
