Visited on May 4 to see what the new charger was. At the time I had no idea that it was for trucks, though I did notice while there that someone had added a picture to the MOVE app. I could probably also have found some of the LinkedIn posts.
The new charger is indicated for bus and trucks per the signs on the floor. There are no official EV signage or any vertical signage at all. The branding on the charger says "eTruck" and 400kW. Based on all the stickers and marketing, it seems to be the actual first 400kW charger by SOCAR.
Nothing changed with the car chargers. It would be quite annoying if you have a car capable of charging at 200kW+ and have to stick to one of the car chargers, potentially even having to share power, while there's a 400kW charger at the same location that will probably sit unused a lot of the time.
The truck charger has a working contactless reader and it's the same price as for cars: 75ct/kWh. They didn't print the plug IDs on the charger, but they appear in the MOVE app and roaming, so there's probably nothing preventing other vehicles from charging there.
The picture of the charging graph is from one of the car chargers. I notice there's always a 20-30kW limit at first at SOCAR locations, and only after a minute does it unlock more power. I see the same behavior at all freeway SOCAR chargers.
I also noticed while reviewing my pictures that it seems like they have already planned for expansion with the parking spaces to the left of the car chargers. The ground was dug and the curb re-done. I need to take a closer look next time.
