Short answer: Paying for a charging session without a subscription or account, typically by scanning a QR code or tapping a bank card.
Explanation
Ad hoc charging lets you pay for a charging session on the spot without having an account with the charging network. You simply scan a QR code on the charger to open a payment page in your browser, or tap your bank card on the contactless reader. No app download, no registration, no monthly subscription.
This is especially useful when you encounter a charger from a network you do not have an account with. EU regulations are pushing for all new chargers to offer ad hoc payment with contactless bank cards, making it easier for drivers to charge anywhere without planning ahead.
The downside of ad hoc charging is price. Networks typically charge a premium for ad hoc sessions compared to their subscribed or registered users. You might pay 0.10-0.20 EUR more per kWh compared to the regular price. If you frequently use a specific network, creating an account will likely save money. But for occasional or emergency use, ad hoc access is valuable and reduces the frustration of needing yet another app.

Common confusion
Some drivers think ad hoc means free. It does not. Ad hoc simply means you pay without needing an account. You still pay for the energy, often at a higher rate than subscribers.
Example
Scanning a QR code on an Allego charger lets you charge immediately via a web payment page, typically at about 0.65 EUR/kWh compared to 0.49 EUR/kWh for registered users.
