Here are some common payment methods for charging at a public charging station:

1. Charging Card: The most common way to pay is with a charging card. A charging card is a special card provided by a charging station provider or a mobility provider. You can use the charging card to access the charging station and start charging. The costs for charging are then billed via your charging card. You usually receive a monthly invoice with an overview of the charging costs. There are various charging station providers and mobility providers that offer charging cards, so you can choose a charging card that best suits your needs and location.
   
   

2. Mobile Apps: Some charging station providers also offer mobile apps that allow you to start and pay for charging. Through the app, you can select the desired charging station, start charging, and view the costs. You can often pay via a linked payment method, such as a credit card or PayPal. These mobile apps often offer additional features, such as finding available charging stations and receiving charging status notifications.
   
   

3. SMS: At some public charging stations, you can also pay by sending an SMS message to a specified number. In the SMS message, you provide the charging station ID and the duration of charging. The costs are then billed via your phone bill or a linked payment method.

It is important to check which payment methods are available at the specific public charging station you want to use. Instructions on how to pay are often found on the charging station itself or on the charging station provider’s website. Additionally, there may also be specific apps or platforms you can use to access multiple charging station providers with a single account or payment method.
