Sharing a charger

A home charger can be shared with other people so they can charge on it from their own app accounts. That used to be something only the owner could arrange, from their phone. Operators can now do it too, from the Manage shared users window in Spark, which is the same list the owner sees in the app: an invitation you send appears in their app, and a person the owner added appears in your window.

This works on Home, Private and Hybrid chargers.

Opening the window

1. Go to Charge Points and open the Home chargers, Private chargers or Hybrid chargers tab.
2. Find the charger and open the action menu at the end of its row.
3. Choose Manage shared users.

Changes take effect the moment you make them. There is no Save button and nothing to submit: Close simply closes the window.

What the window shows

Each section is one access group with its own owner, its own list of shared users and its own limit of five.

• On most chargers there is a single section, Users, covering the whole charger.
• On a private charger with an owner per plug there is one section per plug, headed Plug 1, Plug 2 and so on. See Plug owners.
• A charger that was shared before it moved to per plug ownership also shows a Users (all plugs) section. Those people can charge on any plug. You can revoke them, but new people are always added to a specific plug.

Every section names its owner at the top for context, with an access chip reading Verified, No owner yet or Code expired. The owner is shown read only here. Owners are changed in the charger's own settings, not in this window.

Under the owner, each shared user's row shows their email (or Offline invitation when they were given a printed code), their user ID or invitation code, who added them, and the date. Owner in that line means the owner invited them from the app; anything else is the name of the admin who invited them from Spark.

The count in the corner of each section, for example 2 of 5, is that group's usage against the limit.

Inviting someone by email

1. In the right section, select Invite by email.
2. Type the person's email address.
3. Click Send invitation.

They receive an email with a six digit code. They open the EOSVOLT app, add a charger, and enter the code to link it to their account. Until they do, their row shows as pending.

You can invite people before the charger's owner has redeemed their own code. Invited users can charge as soon as they redeem theirs, whether or not the owner ever got round to it.

Adding someone offline

Select Add user offline and click Create code. A six digit code is generated for you to print or hand over, valid for 30 days. Use this when the person has no email address on file, or when an installer needs to leave something physical behind on site.

Use Download code on any pending row to get that person's code as a printable sheet.

Resending and refreshing codes

Pending rows carry a Resend action that sends the invitation email again. Once an invitation has passed its 30 day life the action becomes New code, which issues a fresh code and emails that instead. A code that has already been redeemed cannot be reused, so a person who lost access needs a new invitation rather than a resend.

Revoking access

Click Revoke on a person's row. Their access ends immediately: the charger disappears from their app and they can no longer start a session on it.

Two things are deliberately blocked:

• You cannot revoke someone who is charging right now. The Revoke action is disabled and the window explains that their access cannot be removed until the session ends. Wait for it to finish, or stop the session from the Sessions page first.
• You cannot revoke the owner here. Removing or replacing an owner is done in the charger's settings, because it has consequences this window does not cover.

The five person limit

Each access group holds at most five shared users, and pending invitations occupy a slot. On a charger with one owner that is five people in total. On a private charger with an owner per plug it is five per plug, so a two plug charger can carry ten shared users between its two owners.

When a group is full the window says so instead of offering a dead input. Revoke someone to free a slot.

Common questions

Where is Manage shared users?
In the action menu at the end of the charger's row, on the Home chargers, Private chargers and Hybrid chargers tabs.

Can I add a shared user to a charger nobody has claimed yet?
Yes. The owner's invitation and the shared users' invitations are independent, so an installer can hand out access on the day of installation.

Why can I not revoke this person?
They have a session in progress on that charger. The action unlocks when the session ends.

Someone I did not invite is in the list. Where did they come from?
The owner invited them from the app. Their row shows Owner where an admin's name would otherwise be.

Does the owner see what I do here?
Yes, it is one shared list. People you invite appear in the owner's app, and the owner keeps the right to revoke them.

Why does this charger have a Users (all plugs) section?
It was shared with those people before it moved to an owner per plug, so their access still covers the whole charger. Revoke them if you want everything scoped per plug.

What is the difference between the shared user limit and the owner?
The owner holds the charger and its settings. Shared users can charge and set their own charging schedules, nothing more. See the driver side in Charger sharing
