> **Description:** Learn how to implement seamless payment solutions for EV charging stations using Vipps MobilePay, making charging easy and convenient for your customers.

# Electric vehicle charging

Customer scans a QR code at the charging station, approves payment in the Vipps MobilePay app, charges their vehicle, and pays only for the actual amount used.

Flow diagram: 6-step EV charging process. (1) Plug cable to turned-off car. (2) Scan QR code. (3) Reserve amount to start charging. (4) Stop charging on phone. (5) Unplug cable from car. (6) Receive receipt for charging in app.

1. **Customer scans QR code** - Customer scans the QR code to access the payment page on their phone.
1. **Initiate payment request** - Reserve an amount (e.g., 350-500 NOK) to cover the charging session.
1. **Customer approves payment** - Customer authorizes the reserved amount in their app.
1. **Start charging** - Charging begins once payment is approved.
1. **Capture payment** - Capture the actual amount used after charging completes.
1. **Cancel remaining amount** - Release the unused reserved amount.
1. **Add order details** - Send order details with the final amount paid.

Here is an example flow:
