A string to a task. Howto?

In my project to display the battery and range status of my EV (renault zoe) on a OLED SSD1306, I've run into a problem.

I used 2 dummy tasks for range and %battery, but I also want to display if my EV is "Charging" or "Not Charging". As this is a string instead of a number, I can't put that into a task. I guess i need to work with rules to get this done but I'm not sure where to start. Has anybody done this before?

What have I got so far?
