How Well Do You Know Tesla's Camping Mode? Discover the Inner Workings!
The algorithm for Tesla's camping mode primarily aims to reduce energy consumption. Even with automatic external circulation, the amount of fresh air entering is still insufficient. In the end, one person in camping mode will approach 1200PPM, and two people will approach 2200PPM. Below 1000 PPM is the ideal value, and you must manually turn on the external circulation to achieve it.
Here’s our experimental process: two people, windows closed, activated camping mode, initial CO2 levels is between 800-1000 PPM. We conducted three experiments lasting one, two, and three hours respectively.
During the experiments, we found that Tesla has a circulation algorithm that continuously switches between internal and external circulation, ultimately stabilizing in external circulation mode without further switching, leading to CO2 levels stabilizing at 2200 PPM.
At this point, manually turning on external circulation causes CO2 levels to drop below 1000 PPM within 10-20 minutes, eventually stabilizing slightly above the external CO2 concentration.
drop under 900ppm, 5.56pm
Conclusion:
- We found that the automatic external circulation in Tesla's camping mode is like having a slightly open window in a bedroom; it saves energy but fails to effectively exchange indoor and outdoor air, resulting in higher CO2 levels. When manual external circulation is activated, it’s like opening the door for ventilation, bringing CO2 levels close to that outside.
- Even if you are alone in the car, the carbon dioxide concentration will stabilize at around 1200PPM, and you should maintain manual external circulation most of the time.
This is the experiment I promised you, it took us two weeks to figure out, hope it helps you.
