PCI DSS compliance is meeting the requirements of the Payment Card Industry Data Security Standard (PCI DSS) for any organization that stores, processes, or transmits cardholder data (or that can impact the security of those environments). PCI DSS is maintained by the PCI Security Standards Council (PCI SSC).
Why PCI DSS Compliance Matters in EV Charging
In EV charging, PCI DSS compliance becomes relevant when a charging business enables card payments through payment terminals, payment gateway integration, or in-app card payments. Compliance helps reduce the risk of payment data breaches and supports the acquiring bank and card scheme requirements for operating ad hoc /pay-as-you-go charging.
What Is In Scope
PCI DSS scope is defined by the Cardholder Data Environment (CDE) and connected systems:
– The CDE includes people, processes, and technologies that store, process, or transmit cardholder data and/or sensitive authentication data
– Systems that do not handle card data but have unrestricted connectivity to CDE systems can also be in scope
– Supporting security systems (e.g., authentication, logging, monitoring) that secure in-scope systems may be included in scope
How PCI DSS Compliance Is Validated
Compliance is typically demonstrated through one of these approaches (depending on merchant/service-provider type and transaction volume):
– SAQ (Self-Assessment Questionnaire) plus an AOC (Attestation of Compliance) for eligible entities
– ROC (Report on Compliance) produced by a QSA (Qualified Security Assessor) for larger or higher-risk environments
PCI DSS v4.0.1 and Key Dates
PCI DSS v4.0.1 is a limited revision that clarifies v4.0 and does not change the effective date for the “future-dated” requirements; many of these requirements become mandatory on 31 March 2025.
Typical Control Areas Required by PCI DSS
PCI DSS requirements generally focus on:
– Secure configuration and network security controls (including segmentation)
– Protecting cardholder data and encrypting transmissions where applicable
– Strong access control and authentication
– Vulnerability management (including patching)
– Logging, monitoring, and incident response readiness
Practical Ways EV Charging Operators Reduce PCI Scope
Many EV charging setups aim to minimize the size of the CDE by design:
– Use certified payment providers and hosted payment flows so card data does not enter CPMS environments
– Use tokenization so the CPMS stores tokens, not card numbers
– Segment networks so chargers/CPMS systems are isolated from payment systems where possible
– Keep card acceptance in dedicated payment terminals and avoid storing card data on chargers
