I don't believe it's possible to claim them on PlayStation if they're for PC. It might be worth contacting EA Help for confirmation, though, as I'm worried I've gotten that wrong. I had a look at the Battlefield Store website too, but that doesn't seem to state if they work on all platforms or not (they seem to be for PC but I'm not 100%).
The "Contact Us" button at the bottom of this guide should let you get in touch with EA Help.
