AlfenCharger 4.42

A Python library for controlling Alfen EV chargers

Alfen Charge station Reader And Controller

A charge station reader and controller for Alfen NG9xx chargers

This code was used in a home built Home Energy Management System (HEMS), to include an Alfen NG9xx charge station into a smart home. You can read more about it in my blog post: How I built a HEMS with solar, a battery and a charge station (in Python)

How to use the code

Import the class and connect to an Alfen Chargestation

from alfenChargestation import alfenCharger
chargestation = alfenCharger('ICU-00001', '192.168.1.X', 0, 20)

Show a single value

chargestation.readMeasurements()
print(chargestation.voltage_l1n)

Control the charge station (single)

# Sets the current to 10 amps
chargestation.changeCurrent(10)

Control a set of chargers in a Smart Charging Network (SCN)

# Set the current of the entire charging plaza to 42 amps
chargestation.changeCurrentSCN(42,42,42)

Change charge using 1 or 3 phases

# Set the number of phases to charge on
# !! Please verify that your car is capable of phase switching during charging !!
changeChargeNumberOfPhases(3)
