Assuming it’s a CCS connector, the charger is always compatible just like the gas pump. The problem seems to be all the unique payment and authorization networks.
I’ve seen more and more gas stations in recent years offering their own apps for payment instead of just the card readers. Usually with some perk, but also they’ll want to debit a bank account instead of charge a card. I haven’t used them for that reason, so I don’t know if they have similar reliability issues seen with charger companies.
The card readers at pumps/chargers seems to be one of the weakest parts and prone to breaking. A big advantage gas stations have is multiple pumps and staff. If a reader breaks, someone knows immediately and they get it fixed quickly. The charger networks seem to suffer from an operations problem where there’s no staff and the companies don’t expect to ever need anyone to check on them.
I still don’t understand why most gas stations aren’t installing a couple of DCFC stations (at least ones with a convenience store). The stations are already in places people go. They have staff, operations, and the convenience store makes more money. They already have power at the site too. They would be in a much better operations scenario to support them, as an incremental “pump” instead of an entire new site. Set them up to encourage 30 minute or less charging.
