Does a kWh indicate consumption per hour?

The short answer to this is a definite no. Everyone encounters the kilowatt-hour (kWh) on their electricity bill, as it indicates the amount of energy consumed, which shows the utility cost for the given month. The unit of measurement shows how much energy the consumer used over a given period, but this does not equate to a per-hour breakdown. The term merely refers to the fact that if a 1000-watt device were to be operated for 1 hour, this is how much energy it would consume. 

For example, if someone uses a 50-watt bulb, it takes 20 hours to consume 1 kWh (which equals 1000 Wh).

What does kW stand for and how many watts is 1 kW?

kW is short for kilowatt, which signifies electrical power as a product of current and voltage (I*U). This unit indicates the power of charging devices in the world of electric cars. For instance, a Voltie  reduces charging time compared to traditional socket charging: it can charge the car at a maximum of 22kW (3x32A) AC fast charging.

One kW is equal to 1000 watts and corresponds to about 1.34 horsepower. Therefore, it is often said that a 50kW charger has the same strength as 50,000 watts, while a car with 110 kW of power is 147 horsepower.

If a 100kW charging power is stated on an electric charging device, it means that in 1 hour, the charger can deliver 100 kWh of energy to the electric car.

This is also important for calculating range

In summary of what has been discussed so far, the amount of energy is commonly measured in kWh, while in the electric vehicle circles, it refers to the maximum capacity of batteries, or the energy consumed projected over 100 kilometers (instead of the number of liters of fuel). The kW unit represents power in the case of electric vehicles.

Based on this, the average range of the electric vehicle can be easily calculated from the average consumption (kWh/100km) and the battery capacity (kWh). From this, one can also see how much it costs to cover different ranges with a given electric car.
