The kilowatt (kW) is a unit for measuring active electrical power, which is the amount of energy actually used or produced by an electrical device at a given moment.
One kilowatt equals 1,000 watts. In the context of electric mobility, power in kW is often used to indicate a charging point’s charging rate. For example, a 22 kW charging point can deliver up to 22 kilowatts of power to an Electric Vehicle, which directly influences the time needed to recharge its battery.
Note: kilowatt (kW) measures instantaneous power, while kilowatt-hour (kWh) reflects a quantity of energy. This distinction is essential to understand charging speed (in kW) versus battery storage capacity (in kWh).
