Famous foreign blogger Bjørn Nyland shared a comparison of energy consumption between a heat pump air conditioner and PTC heating Model 3 in a 3-degree Celsius environment on YouTube.
The car model that uses a heat pump air conditioner consumed 0.735 kWh of electricity in one hour; the model that uses PTC heating consumed 2.17 kWh of electricity in one hour.
In mid-October, Tesla released an updated version of the Model 3. For detailed configuration changes of the new model, please refer to here.
One of the more significant changes is that the Model 3 is now equipped with a heat pump air conditioner. Therefore, the winter range of Model 3 should theoretically be significantly improved.
Bjørn Nyland conducted a comparison test in a 3-degree Celsius environment with the air conditioning of both cars set to camping mode (i.e., always on), with the heating at 21 degrees Celsius for three hours.
After three hours of using the heat pump air conditioner, the power dropped from 62% to 59%, equivalent to a 1% power loss per hour.
After three hours of using PTC heating, the power dropped from 56% to 46%, equivalent to a 3% power loss per hour.
According to Bjørn Nyland’s calculations based on backend data, the car model that uses a heat pump air conditioner consumes 0.735 kWh of electricity in one hour, while the model that uses PTC heating consumes 2.17 kWh of electricity in one hour.
If calculated based on a power consumption of 13 kWh per 100 km (the regular level for Model 3), the car model that uses a heat pump air conditioner can travel an extra 50 km more than the model that uses PTC heating after driving for five hours.
At an average speed of 20 km/h for five hours, the heat pump air conditioner can run 50% further than the model that uses PTC heating. The effect is still very significant.
