Unlike chargers, users are able to add new battery devices using Energy Platform. A new battery can be added as follows:
Head to Battery Storage
Click Add new battery
Fill in the required information
Name: Choose a name
Battery type: Select from the dropdown menu
Serial number: Can be found from the label on the side of the battery
Click Save once you are ready.
Your battery will appear in the table displaying all your battery devices. The devices are by default organized in alphabetical order. If you have a lot of devices, try using the search field in order to verify your device was properly added.
