A charging station requires electricity based on the power (kW) of the charging station. In general, the higher the power of the charging station, the more power it requires. A typical charging station in Belgium can range from 3.6 kW to 22 kW or even more. For example:
A 3.6 kW charging station requires approximately 16 amps of current under full load.
A 22 kW charging station requires approximately 32 amps of current under full load.
So, the power consumption of a charging station depends on its power, with higher powers requiring more power.
