PCI DSS (Payment Card Industry Data Security Standard) is a global security standard that defines technical and operational requirements for organizations that store, process, or transmit payment card data. It is maintained by the PCI Security Standards Council (PCI SSC) and is designed to reduce the risk of cardholder data theft and payment fraud.
Why PCI DSS Matters in EV Charging
EV charging networks that accept card payments—via payment terminals, in-app payments, or hosted payment pages—often fall within PCI DSS scope. PCI DSS helps operators and vendors:
– Protect cardholder data and reduce breach risk
– Meet acquirer/bank and card scheme requirements for processing payments
– Improve trust and reliability for ad-hoc / pay-as-you-go charging
– Define responsibilities between the CPO, CPMS provider, and payment service providers
How PCI DSS Applies to Charging Infrastructure
PCI DSS scope depends on how payments are implemented:
– Integrated payment terminals (unattended) and their connectivity
– Payment gateway integration (authorization, capture, refunds)
– Backend systems that handle payment workflows, receipts, and transaction logs
– Any systems that could access card data, plus networks connected to them (the cardholder data environment, CDE)
PCI DSS Versions and Key Dates
PCI DSS v4.0.1 is a limited revision that clarifies v4.0 and does not change the deadline for “future-dated” requirements. Many new requirements became mandatory on 31 March 2025.
Typical Controls PCI DSS Requires
PCI DSS requirements are organized into broad control areas, such as:
– Strong access control (least privilege) and secure authentication
– Network security controls and secure configurations
– Vulnerability management and timely patching
– Logging, monitoring, and incident response processes
– Protecting stored data and encrypting transmissions (where applicable)
– Regular testing and security validation
Practical Ways EV Charging Operators Reduce PCI Scope
To reduce compliance burden, many EV charging operators:
– Use PCI-listed/validated payment terminals and certified payment providers
– Use tokenization so card data is not stored in the CPMS
– Redirect payments to hosted checkout pages managed by the payment provider
– Segment networks so the charger/CPMS environment is isolated from the CDE
