What Is OCPP EV Charging?
Short answer
OCPP, or Open Charge Point Protocol, is a communication protocol that lets an EV charger exchange data with a backend management platform. In practical charging projects, OCPP can support remote monitoring, user authorization, RFID access, charging-session records, fault reporting, firmware support, and smart charging workflows.
Why OCPP matters for EV charging projects
A simple private charger may only need safe power delivery. A managed charging site usually needs more: driver access control, energy records, remote diagnosis, charging history, payment or reimbursement data, and operator visibility. OCPP helps connect charger hardware with the software platform that handles those tasks.
For distributors and project buyers, OCPP should not be treated as a generic label. The charger, backend, SIM or network connection, firmware version, RFID workflow, time zone, meter data, and acceptance test process all need to match the project.
OCPP project checklist
| Decision area | What to confirm |
|---|---|
| Protocol | Confirm OCPP version, backend platform, charger model, and compatibility test process. |
| Network | Choose Ethernet, WiFi, 4G, or LAN based on site environment and signal stability. |
| User access | Decide whether RFID, app, QR code, private user accounts, or operator approval is needed. |
| Data | Confirm meter values, charging records, fault logs, time zone, and export requirements. |
| Support | Clarify who handles backend setup, SIM cards, firmware, remote diagnosis, and after-sales operation. |
Which chargers can use OCPP?
OCPP can be relevant for AC wallbox chargers, commercial AC chargers, DC fast chargers, and smart portable EV chargers. The need is strongest when the buyer operates multiple chargers, manages users, tracks energy use, or needs remote maintenance.
For Amprisen projects, OCPP is most relevant to MONTA/OCPP AC charger series, commercial AC charging, fleet charging, and OCPP portable EV charger applications.
How buyers should evaluate OCPP readiness
When a supplier says a charger is OCPP-ready, buyers should ask for the exact charger model, firmware status, tested backend, supported network method, commissioning workflow, and acceptance criteria. A single successful connection test is not the same as a complete commercial deployment. Operators should also confirm what happens when the charger loses network connection, how charging records are stored, and how support teams diagnose faults after installation.
For fleet and commercial charging, the most important question is not whether OCPP exists, but which business process it supports. Examples include employee reimbursement, tenant charging, RFID user access, public payment records, remote fault handling, charger grouping, tariff control, and maintenance reporting. These requirements should be written before hardware selection.
Common buyer questions
Is OCPP necessary for home charging?
Not always. A private home charger may only need safe charging and simple app control. OCPP becomes more valuable when charging needs backend operation, reimbursement records, RFID users, fleet management, or remote support.
Does OCPP require 4G?
No. OCPP can work through Ethernet, WiFi, 4G, or another stable network connection. 4G is useful where wired network access is unavailable or where portable chargers need mobile connectivity.
What should buyers send before asking for an OCPP charger quotation?
Share the target country, charger type, power level, connector standard, backend platform, network method, RFID or app requirements, expected quantity, and whether the project needs billing, reimbursement, or operator management.
