Why does the domestic Model 3 only show 380km when fully charged?

It is normal for the system to display 380km after the Model 3 is fully charged. This value is an estimate and does not strictly mean the Model 3 can only run 380km. The NEDC reference data provided for the domestic Model 3 is a range of 445km, which is calculated according to the international driving cycle method. Both values are for reference and do not represent the exact range of the vehicle. Below are the specific details of the vehicle parameters: 2022 Model 3 has a body size of 4694mm*1850mm*1443mm, a top speed of 225km/h, and accelerates from 0 to 100km/h in 6.1 seconds. It is equipped with a permanent magnet synchronous motor with a maximum power of 194kw and a maximum torque of 340mm. The battery type is lithium iron phosphate with an energy capacity of 60kwh, supporting fast charging in 1 hour and slow charging in 10 hours. The transmission is a single-speed fixed gear ratio. In daily life, the power consumption of the car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase power consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the accelerator before a red light, can increase power consumption. The car itself: Heavier cars consume more power because greater driving torque is required for their weight. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and power consumption. Natural wind: Driving against the wind or on windy days increases car resistance and power consumption. Low environmental temperature: In cold weather, the car's computer may control the generator to run at higher speeds to warm up the car, which also increases power consumption.
I've also encountered similar situations and noticed that the Model 3's range display is affected by daily driving habits. The system automatically adjusts the estimated mileage based on air conditioning usage frequency, instances of rapid acceleration, and the proportion of high-speed driving. If you usually drive aggressively or often use the AC, it will show you a more conservative number. I tried driving gently for two weeks, and the displayed range gradually increased from 380 to around 415. The battery management system is designed this way. It's recommended to occasionally perform a deep charge-discharge calibration, which means driving the battery down to below 10% and then charging it fully. This allows the system to re-estimate more accurately. Additionally, it's normal for the range to decrease in winter due to low temperatures, so there's no need to worry too much.
The Model 3 displaying 380 km when fully charged has little to do with battery degradation and is more related to software algorithms. The car has an intelligent energy consumption estimation feature that references your average energy consumption over the last 300 km. If you frequently accelerate hard, overtake at high speeds, or drive at the speed limit, the system will assume you will continue driving this way and provide a conservative estimate. For example, my friend's car, which often drives on highways, shows 30 km less range than mine. To improve this, you can switch to percentage display mode or reset the battery management system at a service center. Temperature also plays a significant role—battery performance is optimal above 25°C, and dropping to 380 km in winter is normal.
