There are several ways to do this:

1. Home charging: If you have installed a charging station or charging cable at home, you can easily charge your electric car without a charging card. You simply connect your car to the charging station or cable, and charging starts. The costs for home charging are usually settled through your own electricity bill.
   
   

2. Public charging points with payment options: Some public charging points accept payments via various methods, such as credit cards, mobile apps, or contactless payments. At these charging points, you don't need to use a charging card and can pay directly to charge your car.
   
   

3. Roaming services: There are roaming services available that give you access to different charging networks without needing multiple charging cards. These services allow you to pay and charge at different points via a single registration or mobile app.

While a charging card can be convenient for easy access and integrated payments at different charging points, it's not always necessary to have one. As long as you have access to a home charging station or public charging points with alternative payment options, you can charge your electric car without using a charging card.
