Most cost questions come down to three rules: prices are entered in cents, they apply to future sessions only, and the smart-charging price limit is not the same field as the site price.
Entering the energy price
The site energy price field is in cents per kWh. To charge 0.16 €/kWh, enter 16. Entering 0.16 sets the price to 0.0016 €/kWh, which is why sessions can come back costing a fraction of a cent. The same applies to transmission cost and other fees: 5 cents/kWh is entered as 5, not 0.05.
Users with the Member role cannot edit prices. If the price fields are not editable, ask for your role on that site to be raised (see: VOOL user roles and permissions).
Changing a price does not re-rate past sessions
Editing a tariff applies from that moment onward. Completed sessions and existing reports do not change, so that historical invoicing stays stable.
If sessions were recorded under a wrong price — or show a cost of 0 — VOOL can recalculate the affected sessions on request. Contact support with the site name and the date range, and tell us whether the site pricing was changed recently.
What the report columns mean
Energy cost — energy at the site's configured energy price.
Transmission cost — the transmission component you configured.
Other fees and taxes — taxes are calculated from the country you have configured, plus any additional fees set for your area or country. It is a locale-driven catch-all rather than a fixed list.
Total cost — the sum of the above.
The smart-charging price limit is a different setting
The maximum price used by price-limited and cheapest-hours charging is compared against the price the system has for your site. If you set the limit to the bare Nord Pool spot price while your delivered cost also includes transmission and taxes, few or no hours will qualify and charging will appear not to start. Set the limit against what a kWh actually costs you.
Market-based modes only become available once the site's pricing type is set to Market in the site detail view.
Metered energy will not match your utility bill exactly
VOOL counts charging sessions. Your energy provider's meter also includes the charger's standby consumption, so a small difference is expected. A large gap is worth investigating — send us hourly data from your provider and we will reconcile it.
Public-charging invoices
To get your name or company on the invoice, log in at charge.vool.com before you start charging. Sessions paid by card without logging in are anonymous.
Support can retrieve a receipt for a card-paid session — we need the date, approximate time and charger location.
An invoice that has already been issued and paid cannot be amended.
