Power
The motor power of a vehicle, in horsepower.
In general, the power of electric motors is indicated in watts. However, in electric transport, this designation is also often indicated. This is done for the convenience of comparison with internal combustion engines: for internal combustion engines, especially in vehicles, horsepower is traditionally used, and it is more convenient for some users to evaluate the power of motors by this designation. At the same time, if the need arises, some units are easily converted to others: 1 hp. ≈ 735 W.
For the power value in general, see the relevant paragraph below.
Power
The motor power of a vehicle, in kilowatts. In addition to them, horsepower is also used (for more details, see above).
Let us clarify that in this case, we are talking about
maximum power; the actual power can be adjusted while driving with the help of the accelerator. And in some models, it may even be possible to set a limit on the maximum power.
A more powerful motor allows you to carry more weight, reach higher speeds and/or have more torque. However, the energy consumption from the battery will also be high, and the battery life, with the same battery capacity, will be correspondingly less than when using a less powerful motor. Also note that in many countries, motor power is a criterion for classifying an electric vehicle as one or another variety. For example, according to this criterion, motorcycles and scooters can be formally separated, requiring different driving licences.
Battery capacity
The capacity of the battery installed in the vehicle, in ampere-hours.
Theoretically, the battery life of the vehicle directly depends on this parameter: a more capacious battery can supply the electric motor longer. However, the actual amount of stored energy depends not only on the capacity in amp-hours but also on the nominal voltage of the battery. A more correct unit in this sense is watt-hours, taking into account the difference in nominal voltages; see "Battery capacity" below for details on this designation. Additionally, the operating time on a charge will depend not only on the characteristics of the battery but also on the power consumption of the vehicle itself — and it is determined by the motor power and several other parameters.
