Your Car.
Your Data?
The EU Data Act says yes.
But APIs are still missing!
Smart charging at home depends on vehicle data.
Your manufacturer has it.
You should have access, too - without third-party cloud services or subscriptions.

🚗💾 Your Car, Your Data?

The EU Data Act is in effect – but most manufacturers don't give you access to your own vehicle data!

For smart charging, we need real-time APIs. Not email requests and ZIP downloads.

Good question. I assume lower upfront costs and lots of available roof-space. But I'll ask Markus, when we meet again.
