What is the actual range of a car advertised with 400 km range?

[Leonardo]

For cars typically advertised with a 400 km range, the actual range is usually around 300 km. Here are some additional details: 1. Range reduction: Due to varying usage conditions, such as the temperature setting of the air conditioning or using the heater in winter, the range of an electric vehicle can decrease to varying degrees. Taking the heater as an example, in a fuel-powered car, the heater can directly utilize the residual heat from the engine without consuming much energy. 2. Factors like temperature and road conditions: In winter, when temperatures drop, the range of electric vehicles often decreases further. The lithium batteries installed in the vehicle, due to the low winter temperatures, experience reduced activity, leading to decreased discharge capacity. As a result, the range of the electric vehicle becomes shorter.
