EV charging standards and protocols define how electric vehicles, chargers, and backend systems interact across the charging ecosystem. EV charging standards set technical and regulatory rules for hardware, safety, and energy use. EV charging protocols define digital communication between chargers, vehicles, operators, and service platforms. EV charging standards group into hardware and connector standards, electrical and safety standards, and smart charging and energy standards. EV charging standards vary by region due to grid design, regulation, and vehicle markets across Europe, North America, and Asia-North Pacific.
EV charging protocols structure how charging networks operate at scale. EV charging protocol categories include charger management and control, roaming and interoperability, and vehicle-to-charger communication. EV charging protocols in common use include OCPP for charger control, OCPI for roaming and data exchange, ISO 15118 for vehicle-to-charger communication and Plug and Charge, OCHP for clearing house-based roaming, and eMIP for interoperability between mobility providers and operators. EV charging protocol adoption differs by region, with Europe relying heavily on open roaming interfaces, North America focusing on network control and bilateral integrations, and Asia-North Pacific combining regional standards with global protocols.
EV charging standards and protocols serve different roles but function together within a single charging workflow. EV charging standards define physical, electrical, and safety requirements, while EV charging protocols handle data exchange, authorization, pricing, and control. EV charging interoperability depends on alignment between these layers across regions and stakeholders. EV charging software platforms such as Monta support this alignment through compatibility with widely adopted standards and protocols, enabling compliant hardware operation, protocol-based charger management, and scalable roaming integrations across markets.

What protocols are used for EV charging?
The protocols used for EV charging are communication rules that enable data exchange between the electric vehicle, charging station, backend systems, and the power grid during a charging session. EV charging protocols govern signaling, control, authorization, and data flow rather than physical power transfer. EV charging protocols complement hardware and electrical standards by coordinating how systems interact before, during, and after energy delivery.
EV charging protocols operate across layered roles within the charging ecosystem. EV charging protocols at the vehicle layer manage identification, security, and charging parameters between the car and the charger. EV charging protocols at the network layer manage monitoring, control, pricing, and session data between chargers and backend platforms. EV charging protocols support authentication, billing, diagnostics, and smart charging through structured message exchange.
EV charging sessions rely on multiple protocols working in sequence. EV charging protocols handle vehicle-to-charger communication separately from charger-to-backend communication.

eMIP sees most use in European interoperability frameworks. eMIP adoption reflects environments that rely on formal roaming agreements and structured clearing relationships between multiple market participants.
How do EV charging protocols differ by region?
EV charging protocols differ by region due to variations in protocol adoption, regulatory alignment, and market practices that influence how charging communication, roaming, and management are implemented across regions. EV charging protocol usage reflects regional policy choices, grid regulation, and historical infrastructure development rather than physical charging hardware.
EV charging regions adopt different protocol mixes because market structure shapes priorities across management, roaming, and vehicle communication layers. EV charging protocol categories vary by region, with some markets emphasizing open roaming interfaces and others prioritizing network control or bilateral integrations.
