Dynamics on the passport and in practice - why they do not match

Both parameters have the right to life. But, unfortunately, the units indicated by you are often used for other purposes.

If we are talking about the power of an electric motor, then it is indicated in kilowatts (kW) - as for ordinary cars.

And when they want to evaluate the capabilities of the battery, which are directly related to the mileage of an electric vehicle on a single charge, they indicate its energy supply (energy intensity) - it is usually measured in kilowatt hours (kWh). In the old manner, this value is sometimes called the battery capacity, but this is not entirely correct.
