Controlling two cars

[mvso]

Is your feature request related to a problem? Please describe.
I have two cars and one home charger. Each night I typically plug in the one with the lowest charge. I want to be able to use the features of this integration on both cars

Describe the solution you'd like
I want to have the app control multiple cars using the same charger (one at a time)

Describe alternatives you've considered
An automation sensing the charging status from each of the cars (and possibly the charger), triggering an update of the value of two helpers, SOC and SOC target based on values from the car connected

Additional context

shouldn't it be possible to add the integration twice and set it up for each car?

I have the same issue. A workaround is to have the integration setup with home assistant helpers for the soc and charge speed and have a separate automation to update the helpers based on which car is plugged in. This is determined by location of the car and whether it is plugged in the charger. This does rely on the integration of the car, but for Audi this works fine. In the past I've used Tronity, which was also working.

I have had success with the following:
I made a couple of hjelpers that the integration is linked to:

Furthermore, I have an automation updating the helper values every 10 minutes:
