Plug owners

A private charger normally has one owner who holds the whole charger. A charger with two plugs can instead be set up with an owner per plug: plug 1 belongs to one resident, plug 2 to another. Each owner sees only their own plug in the app, charges only on it, and is billed only for it. This is what makes a two plug charger a practical fit for a condominium, where the cost of one box is shared between two parking bays.

Setting a charger up with owners per plug

1. Go to Charge Points → Private chargers and either click Add new private charger or open an existing one for editing.
2. Fill in the charger details, including the location, the brand and the charger model. The model is what tells Spark how many plugs the charger has, so the next step stays locked until you have picked one.
3. Under Owner settings, switch from Charger owner to Plug owner.
4. A section appears for each plug, headed Plug 1, Plug 2 and so on. Fill in each one.
5. Save.

Assigning an owner to a plug

Each plug section offers the same two invitation methods as a normal charger owner:

• Add owner via email: enter the resident's email address. They receive an invitation email with a redemption code when you save, and they redeem it in the EOSVOLT app exactly as any other charger owner does.
• Add owner offline: leave the plug unassigned for now. You can come back and add an owner later, or generate a code for offline distribution from the charger's settings.

A plug can be left without an owner indefinitely. An unassigned plug is simply nobody's: it does not appear in anyone's app and nobody is billed for it.

If the module is enabled you will also see a Subscription block inside each plug section, for charging a fixed monthly fee per plug. That is covered in Monthly billing for plug owners.

Who can charge on which plug

Access follows the plug, and Spark enforces it at the charger:

• A plug owner can charge on their own plug. Attempting to start on their neighbour's plug is refused.
• A shared user added to a plug can charge on that plug only. They inherit their plug from whoever invited them, so a plug owner sharing from the app automatically shares only their own plug.
• Someone who was shared onto the charger before it moved to owners per plug keeps access to every plug. They appear in a Users (all plugs) section, where you can revoke them but not add more. See Sharing a charger.

Each plug owner can share their own plug with up to five people, so a two plug charger supports two owners plus ten shared users.

What the charger list shows

On the Private chargers tab, the Owner column shows one line per plug, each tagged with its plug number, so you can see at a glance which bays are taken and which are still free. A plug carrying a monthly subscription fee is marked with a subscription icon on its line.

The list is deliberately compact on this tab: the charger's alias sits inside the charge box ID cell and the separate user ID column is folded into Owner, because that column now has to say something different for every plug.

Changing a plug's owner

Replacing the email address on a plug hands that plug to someone else. The existing invitation is cancelled, a fresh code is issued, and the new person is invited when you save. Saving a plug you did not change never re-sends its invitation, so you can edit one plug without disturbing the other.

Unlike replacing the owner of a whole charger, replacing a plug owner does not create a replacement charger record. The plugs share one physical box, so the box cannot be swapped out for one resident's sake.

Going back to a single owner

Switching a charger from Plug owner back to Charger owner collapses the plugs into one owner again, and drops the per plug subscription fees with them, since a fee belongs to a plug. Do this only when the sharing arrangement has genuinely ended, and tell the residents first: their app access and their billing both change.

Changing the operator, the charger model or the charger type also returns the charger to a single owner.

Common questions

Why can I not switch to Plug owner?
Either the charger is not a Private charger, or you have not selected a charger model yet, or the module is not enabled for your operator. The tab stays unavailable until a model is chosen because the model defines the plugs.

Can I use owners per plug on a home or hybrid charger?
No, private chargers only.

What happens if I only fill in one plug?
Nothing breaks. The other plug stays unassigned, invisible in the app and unbilled, until you come back and assign it.

Can one person own both plugs?
Yes. Enter the same email address on both. They will receive an invitation per plug.

Can a plug owner charge on the other plug in an emergency?
No. The charger refuses it. The other owner can share their plug with them if they want to allow it.

Does the second owner see the first owner's sessions or costs?
No. Each owner sees only their own plug, its schedules, its sessions and its bill.

Do plug owners still get scheduled charging?
Yes. Schedules are per owner, so both residents can set their own without affecting each other.
