Accelev v2 Control program
Just recently completed the control program for the Accelev v2 2 phase EV charger.
The charger can transform 400V 2 phase down to 250V 1 phase which comes handy for cars that are equiped with only 1 phase on-board charger.
The technique utilized are an IoT platform running on a raspberry pi 4, running ubuntu 20.04 LTS.
Influxdb v2 as database, recording everything passing the mqtt broker on localhost.
Grafana for graphs.
Node-RED for flow control (this is currently where the program is running).
And as you can see in the image below, the current in main central i pretty close to the fuse limit throughout the charging time.
The three graphs in the top represents the current in the main central.
The three graphs in the bottom represents the current in the garage (where the charger is located).
The charger does not yet allow to communicate directly with the control program, it requiers connection with the server over internet and therefore won't work without internet connection.
From what I've heard, the vendor are working on implmentation of the apis directly in the local charger.
