To display your charging stations on Google Maps, you need to add them as a missing place on Google.
Step 1: Search for address
Type the address of your charging station into the search field.
Click on the option to "Add a missing place."
Step 2: Create location
Choose 'Electric vehicle charging station' as the category and enter a name for your charging station.
Step 3 (optional): add additional details
Provide any additional information about the charging station, such as contact details, operating hours, or other relevant data.
After adding the charging station, Google will review the information, and once verified, it will be displayed on Google Maps.
