Connectivity issues significantly impair EV charging station reliability by disrupting critical functions like authentication and payment processing. Over half (55%) of charging failures arise from stations losing cellular connectivity, which most networks rely on to validate users and process transactions. This can leave drivers unable to initiate sessions even when hardware is functional.
Key impacts include:
- Authentication failures: Stations cannot verify user accounts or payment methods without a cellular connection.
- Payment system disruption: Network loss prevents transactions, though some networks like Electrify America default to free charging during outages.
- Session initiation errors: Drivers may encounter frozen screens or error messages even if the charger itself isn’t broken.
While Tesla Superchargers (4% problem rate) and Rivian’s network (5%) demonstrate better reliability, providers like Shell Recharge (48% failure rate) and EVgo (43%) struggle with these connectivity dependencies. Hardwired internet connections could reduce failures but are cost-prohibitive for widespread adoption.
