Credit card readers at EV charging stations typically fail due to a few key issues:
- Connectivity Problems: Since most EV charging networks rely on cellular connections for payment authentication, issues with network connectivity can lead to payment failures. This is common when a station cannot connect to its network, often due to cellular service limitations.
- Hardware and Technical Issues: Physical damage or failure of the reader itself can also cause problems. This could include malfunctioning hardware or software issues within the charging station, which can freeze or prevent the reader from functioning properly.
- Payment Method Issues: Sometimes, issues arise from invalid or expired credit or debit cards stored in customer accounts. Additionally, problems with public key infrastructure security certificates can contribute to failed authorizations.
- Insufficient Maintenance: Deferred maintenance on charging stations, including their payment systems, can lead to increased failure rates over time.
Despite these issues, credit card reader problems account for a relatively small percentage of overall charging station failures, often cited as around 1%.
