Description (excerpt):

Failure to accept and process payment is a cause of public electric vehicle (EV) charging session failures. This document summarizes EV charging payment challenges and proposed solutions. Data are not available to rank the severity of payment issues; however, input from members of the National Charging Experience Consortium (ChargeX Consortium) suggests that payment issues present ongoing challenges. The input also indicates that credit card readers have been more prone to failure than other payment methods. The multiple EV charging payment options commonly provided for customers at public charging stations increase the complexity in solving the issue. This document considers the following forms of payment: credit card readers, radio frequency identification (RFID), near-field communication (NFC), apps, Plug & Charge, and phone call, text, or short message service (SMS).
