Hello,

I used the HTTP URL Thing to link in my Bender CC613 charge controller of my wallbox. Is there a possibility to contribute this to OpenHAB?

The configuration of thing is as follows:

Currently I’m only reading the status. But in the future, I’ll extend it to load my vehicle dependent on photovoltaic power available.

In the meantime I also wrote a thing and an item configuration for the Modbus TCP access to the Bender CC613 controller. The CC613 provides register “#1000 Hems Current Limit (A)” that allows to set the maximum current the vehicle should load with. I wrote a rule to continuously set this register based on photovoltaic energy production and the building’s excessive energy available. This increases the own generated energy usage from photovoltaic system (“Eigenverbrauch” in German) by only consuming energy, when it’s available excessive (“PV-Überschussladen” in German).

I uploaded all reference configurations to GitHub here: GitHub - tobylorenz/openhab-config: OpenHAB reference configuration (things, transformations, items, rules)

Hi,
I also would like to get a Bender CC613 based wallbox.
Are you able to read the SOC (State of Charge) of your car over the PLC Communication of the Bender?

Is this available over Modbus Register?

This would be the main advantage over all other Wallboxes out there.

Thanks a lot in advance for your reply!

Hi,

at least the wallbox supports the protocol (ISO 15118) to the vehicle. So I’m confident that the SOC can be read.

However my vehicle doesn’t support it, so I’m not able to confirm it.

Bye
Tobias

Unfortunately ISO 15118 does not transmit the SoC in this scenario: ISO 15118 transmits the SoC only in DC-charging mode (i.e. with “Fast chargers”; Home wallboxes always use AC, otherwise they would cost a lot more)
The Porsche Taycan with the Porsche Mobile Charger Connect is the only combination of vehicle and charging equipment I know of that can show the SoC using the ISO15118 connection (without need for a separate LTE connection to the car or manufacturer web page)

A “standard” ISO15118 wallbox may support this in the future with a newer revision of the ISO15118 standard (released earlier this year, ISO15118-20, “dash-twenty”), but don’t expect this in 2022 or even (early) 2023.
As a side note: EVCC uses the car’s LTE connection to the car manufacturer’s backend to retrieve the SoC from the backend. It does not get this information from the Wallbox.

Thank you both for your reply!

Sad to hear, that there seems to be only one car/wallbox combination in the year 2022 which exchange the SOC directly.

I hope that many cars will adopt the new ISO15118-20 but I guess only cars coming to market 2023 or later will get this feature
