What Is OCPP and Why Does It Matter for EV Chargers?

OCPP (Open Charge Point Protocol) serves as the global standard communication protocol between an EV charging station and a central back-office management system.

The main benefit of OCPP lies in hardware and software interoperability. Without OCPP, a buyer must use the proprietary software from the hardware manufacturer. If the software provider closes or increases prices, the operator has to replace the physical chargers. With OCPP compliance, operators can change network management software providers at any time and keep the physical charging stations unchanged.

lOCPP 1.6J: The current industry standard. OCPP 1.6J supports smart charging features, load balancing, and JSON-based communication over WebSockets.

lOCPP 2.0.1: The upgraded standard. OCPP 2.0.1 adds enhanced cybersecurity measures, better device management, and native support for ISO 15118 that enables Plug & Charge capabilities.

Which Certifications Should EV Chargers Have?

Deployment of uncertified chargers creates serious fire risks, cancels property insurance, and often removes projects from government rebates. Buyers must confirm the following global safety and performance standards.

lSafety Certifications (UL/ETL/NRTL, CE, TUV): In North America, UL certification confirms that the hardware has passed strict thermal and electrical failure testing. In Europe, CE marking stands as a mandatory requirement. TUV delivers thorough third-party safety validation that gains wide global recognition.

lISO 15118: This standard governs the communication between the EV and the charger. The standard turns mandatory for Plug & Charge. The standard enables the charger to recognize the vehicle in an automatic way. Session authorization comes next. Billing starts without any RFID card or mobile app.

lPerformance & Metrology (ENERGY STAR, CTEP, MID): ENERGY STAR confirms low standby power consumption. CTEP (California Type Evaluation Program) and MID (Measuring Instruments Directive in Europe) verify the precision of the energy meter in the charger. Law requires such approvals when station operators charge customers according to kilowatt-hour usage.
