Hopefully it comes with an OBD socket you can connect to as with all other cars.

That should provide basic diagnostics/stats. No need for "apps".

It's actually not required for EVs - Tesla has started to drop it from recent models. I bet these guys would omit it as well to save money.

Or use it because using an existing standard makes everything that needs to interface with it cheaper/easier.
