Como calcular o Poder de carregamento
(Single Phase or Three Phase)
To calculate the charging power, you will need the number of phases, voltage, and amperage supplied to the charging station.
In a three-phase installation the manner in which the charging station is connected to the network is also important.
It will depend on whether the voltage is 230 V or 400 V, arranged in a star or delta connection.
If you have this information handy, you can easily calculate the values using the following formula:
Charging power (3.7 kW) = Phases (1) x Voltage (230 V) x Amperage (16 A)
Load power (single-phase alternating current):
Charging power (22 kW) = Phases (3) x Voltage (230 V) x Amperage (32 A)
Load power (triple phase alternating current), star connection:
Load Power (22 kW) = Root (3) x Voltage (400 V) x Amperage (32 A)
Load power (triple-phase alternating current), delta connection.
If you want to achieve a load power of 22 kW, your electrical installation should be three-phase with a 32A amperage.
