The Wallbox Smart Meter (Dynamic Power Meter) helps to distribute the input power so that the electric car is not charged beyond its instantaneous power consumption.
The Wallbox Smart Meter is an external power meter that communicates with the charging station to dynamically manage its power.  Example: The power input of a house is 14 kW.
Charging of the electric car starts at the maximum power of the station (e.g. 11 kW), while at the same time the washing machine, kettle, air conditioner are switched on, with an instantaneous power demand exceeding 3 kW.
If the power of the house’s inlet is exceeded, the inlet machine switches off and the house loses power.   To avoid power cuts when charging an electric car, a dynamic power controller is recommended to automatically reduce the power to the station if other electrical appliances are in use at the time.
