EV Charger (type 2) with RESTful API and Wifi recommendations?
-
Hi there!
Time for me to invest in a EV Charger (type 2).
Of course I'd like it to have a RESTful API and Wifi. Even better if it could connect to my MQTT server as well. 22 kW would be fine.
I can't just install any "smart" charger that measures the used grid power because it can't determine the direction of the current. I export solar energy daytime which makes power flow outwards to the grid. I'd like to be able to set the max power depending on how much solar power I produce and how much I can import. If I can control when charging occurs I can also select the cheapest hours.
BTW, I prefer to buy my EV charger in Europe.
Cheers!

@รอเร-อ take a look at openevse https://shop.openenergymonitor.com/openevse-wifi-emoncms-ev-charging-station-diy-kit/
Just got one, delivered in a couple of days from UK - 'deluxe' version with ESP8266 is fully controllable via mqtt or built-in app. Assembly instructions aren't great. Our EV not arrived yet so I can't tell you if it works - I expect it will.

@รอเร-อ btw Normal single phase type 2 charging on an EV is 32a = 7 Kw. If your ev can charge at 22Kw, then it will need a 3 phase supply. OpenEVSE can do this but you will need to put a 3 phase contactor in it.

RThanks a lot. That seems to be exactly what I'm looking for. I didn't order the kit though. I ordered the EmonEVSE WiFi Connected EV Charging Station IEC 60947-5 (Type-2)
I'm very excited to get started. Ohh... I'll need an EV too... ha ha
