Foreign agency EVSmartBlog recently decided to conduct a dangerous experiment to check whether the Tesla Model 3 can keep you warm for about two days (about 50 hours) in the weather surrounded by blizzards, and the passengers on the car will not be injured by frostbite or carbon monoxide poisoning.
It is reported that these testers selected three different Tesla Model 3s in the mountains of Japan for testing (overnight inside the vehicle), their air conditioners were adjusted to different settings, and they needed to pay attention to how long it took for the car's battery to drop from 80% to 10% when the outside temperature was -5°C. The test took place from January 27 to 29 at the parking lot of the Zao Astria Hotel in Yamagata Prefecture (north of Tokyo) and lasted 38 hours, which is located at an altitude of 940 m above sea level. The weather in the test days was cloudy, with occasional snowfall, with an average temperature of -5°C, and the area has accumulated a lot of snow due to the long period of snowfall in the area.
Car Settings:
"Comfort"; 2021 Model 3 long battery life (red). Air conditioning @ 20 °C, automatic air conditioning, air circulation in the car, seat heater has been turned off;
"Good"; 2019 Model 3 performance (blue). Air conditioning @ 18°C, automatic air conditioning, air recirculation in the car, seat heater off;
"Forgiving"; 2019 Model 3 long endurance (white). Air conditioning @ 16°C, automatic air conditioning, seat heaters turned on in all seats and equipped with electric blankets.
The final result indicates that the battery status (SoC) drops to 10% at 80% of the time: 33 hours for air conditioning at 20°C, 51 hours for air conditioning at 18°C, and 40 hours at 16°C (under heated seats and electric blankets).
This level of power consumption was also lower than they initially expected, and they eventually stopped experimenting when the car's remaining battery reached 10%.
Of course, most drivers if unfortunately trapped in the snow, can not simply ensure that their batteries must be used from 80%, so the test results also show that Tesla in only 40% of the battery can also operate in 20 ° C air conditioning for 14 hours, in 18 ° C air conditioning for 22 hours, in 16 ° C air conditioning for 20 hours (using heated seats and electric blankets), although the car must provide a safe environment for passengers for a long enough time, But in many countries, 14 hours is also usually enough for emergency services to respond to situations.
In addition, they compared and tested electric vehicles and conventional gasoline vehicles separately to see if there were some other results, and the final test results were also different, in a snow-covered fuel vehicle, carbon monoxide (CO) levels rose rapidly, which adversely affected the occupants of the car. A common problem for drivers trapped in gasoline cars is the level of carbon dioxide in the cabin, which can lead to higher levels of carbon dioxide in the vehicle if the exhaust part of the vehicle is blocked by snow. And this test was measured in a car covered with snow to the top of the wheel arch, the vehicle also turned on the air conditioning of the external air circulation, the carbon monoxide meter left on the dashboard showed as 322 PPM in 3 minutes, at this level, the average person will experience headaches and nausea within 2 hours, for a fair comparison, they did the same test on the model 3, which was also covered by snow, and found no significant increase in carbon dioxide content.
Summarizing this test, we found that whether the occupants are in an electric car or a gasoline car, being trapped in the snow is dangerous, if the snow continues to accumulate, the driver even needs to clean the snow around the vehicle frequently to avoid blocking the door, in addition to the carbon monoxide in the car may also lead to poisoning of the members of the car, so please the relevant drivers must contact the relevant emergency department even if they contact the relevant emergency department, and seek help from the professional department.
