Currently, invoices can only be downloaded individually in PDF format. If you want to retrieve all invoices for a specific year, you will need to download them individually, one by one.

To download invoices via the website:

1. Log in to your account on the Kia Charge Web Portal.
2. Go to the Invoices section in the top row of the page.
3. Use the date filter to select the desired year.
4. Download each invoice individually as a PDF.
