This was mentioned at WWDC for iOS 14. This is currently not supported (10/02/2020) by BMW. Although I suspect BMW will be building support for this in the future. This could be awesome for i3 owners with CarPlay.
The premise from my conversation with Apple Support is this "EV Routing" feature will allow you to connect your BMW i3 to Apple Maps. Certain critical elements are shared. Such as desired route, charge status, updated ETA. I'm thinking BMW would need to develop around Apple's EV Routing API.

Follow the steps in the sub-sections included right ahead to learn how to set up, configure and use the handy Apple Maps electric vehicle routing feature on your iOS device.
1. Open the App Store app on your iOS device.
2. In the App Store, search for the manufacturer of your electric vehicle such as “Tesla.”
3. Download your vehicle’s app (be sure it supports electric vehicle routing) to your iOS device.
4. Open the app you just downloaded, then follow its setup instructions.
5. Now launch the Maps app on your iOS device.
6. Tap “i” in the Maps interface.
7. Choose the option “My Vehicles.”
8. Tap “Connect Your Electric Vehicles.”
9. Select your electric vehicle, then follow the onscreen instructions
The key missing element today is making sure your vehicle app support EV Routing.
What also is interesting from the WWDC photo, it appears BMW (and Ford) are launch partners for this new EV Routing feature. If properly implemented by BMW this could bring our BMW's closer to par with Tesla's superior automatic mapping/charging functions.
