The Public Service Commission of Maryland convened its fourth Electric Vehicle Supply Equipment Work Group meeting on September 22, 2024, to discuss critical issues surrounding electric vehicle (EV) charging infrastructure and payment methods. The meeting focused on regulatory standards for charging fees and the implementation of payment systems for EV chargers.

A significant topic of discussion was the proper method of sale for electricity used at EV chargers. Participants emphasized that charging should be based on kilowatt-hour usage, which is the recognized standard in Maryland. Additional fees, such as transaction fees or charges for occupying a parking space after charging, can be applied as long as they are clearly communicated to consumers.

The group also explored the challenges associated with payment systems for different types of chargers. While DC fast chargers typically accept credit cards, Level 2 chargers face hurdles due to the high cost of credit card readers relative to their overall expense. This could potentially limit the deployment of these chargers across the state. Members suggested a cautious approach to implementing regulations requiring credit card readers, especially given emerging technologies that may allow vehicles to authenticate payments directly.

Further discussions highlighted the need to differentiate between publicly accessible chargers and those intended for fleet or multifamily use. The group considered the implications of retroactively applying new payment standards to existing chargers, suggesting that future installations should prioritize compatibility with multiple payment methods, including credit cards and toll-free numbers.

Overall, the meeting underscored the importance of establishing clear guidelines for EV charging fees and payment systems to enhance accessibility and consumer confidence in Maryland's growing EV infrastructure. The work group plans to continue refining these recommendations as the industry evolves.
