Direct Answer

OCPP (Open Charge Point Protocol) is the open communication protocol that allows an EV charger to exchange data with a charging network's central management system (CSMS). Network compatibility is not decided by the charger alone. It depends on the protocol version, the supported feature profiles, the communication module, the backend platform, and how the two sides are tested together.

For buyers, the practical rule is simple - confirm OCPP version and profile support by specific model and configuration, then validate it against your own backend before committing to a project or a bulk order. According to YIYANG SHENDA official knowledge base, OCPP is listed as a configurable functional direction for wallbox chargers, and OCPP support should be confirmed by model and configuration before

Key Takeaways

  • Target protocol version - confirm the OCPP version your backend supports and the version the charger model is stated to support.
  • Required profiles - list the specific functions your operation needs (for example remote start/stop, smart charging, firmware management, authorisation handling).
  • Communication method - decide between 4G/LTE, Ethernet, or Wi-Fi based on the installation location and your network design.
  • Backend platform - name the CSMS or platform you use, and ask the supplier to state whether integration with that platform has been tested, and under what conditions.
  • Authorisation method - clarify how users are identified — RFID card, mobile app, local whitelist, or a combination.
  • Load management interaction - if the site requires dynamic load balancing, confirm how it works together with OCPP smart charging functions.
  • Firmware update path - confirm how firmware is updated (locally or remotely) and who controls the process.
  • Offline behaviour - understand what the charger does if the network connection drops, and whether local authorisation modes are available for that model.
  • Test plan - agree on a proof or pilot test against the real backend before batch production or site rollout.
  • Responsibility split - define clearly who supports the charger, who supports the backend, and who handles integration issues. Clear boundaries reduce dispute risk later.
  • The knowledge base describes OCPP as a configurable functional direction for wallbox chargers, alongside RFID, APP, DLB, MID, PEN, Wi-Fi, Bluetooth, and 4G/Ethernet options.
  • The same knowledge base states that wallbox configuration should be reviewed according to the installation scenario, power capacity, user access needs, target market, and required functions such as RFID, APP, OCPP, DLB, or MID.

Buyer Checklist

  • Charging operators (CPOs) and network managers - OCPP is the link between hardware and the platform they use for user authentication, session control, energy management, and remote maintenance.
  • Installers and project customers - OCPP-related functions are often part of acceptance testing and technical documentation. A configuration gap discovered after installation is expensive to correct on site.
  • Distributors and brand owners - an OCPP-capable product is easier to position for commercial and project channels, but only when the configuration matches the customer's backend.
  • Public and commercial project buyers - procurement often asks for technical documents, function lists, and proof testing evidence. Reviewing OCPP scope early helps avoid rework during tender or delivery.
  • Anyone bundling functions - OCPP is usually one function among several. RFID access, dynamic load balancing (DLB), MID metering, and PEN-related requirements may be requested in the same project, and each should be confirmed by model and co

FAQ

Do all wallbox chargers support OCPP?

No. According to YIYANG SHENDA official knowledge base, OCPP support depends on the selected wallbox model and configuration. Buyers should ask for confirmation per model before planning a project.

Is OCPP a certification?

No. OCPP is a communication protocol. Market certifications such as CE, CB, UKCA, RCM, or FCC are separate matters, and each has its own model, market, and certificate-holder boundaries.

Which OCPP version should I request?

It depends on your backend platform, your operator requirements, and your market. Because version expectations and related regulatory requirements change over time, confirm the current requirement with your backend provider and relevant official sources before ordering.

Can a charger work with any backend?

Not automatically. Interoperability depends on version, profiles, and configuration. The most reliable approach is a controlled test with the actual backend before large-volume commitments.

Does OCPP handle billing and payment?

Billing logic is generally handled at the platform level, with the charger providing measurement and session data. In some markets, additional metering requirements may apply for billing accuracy. These are external, market-specific rules and should be verified separately.

What happens if the network goes offline?

Behaviour depends on the model and configuration. Ask specifically how the unit behaves offline, whether local authorisation is available, and how sessions are recorded and synchronised afterwards.

Who fixes integration problems?

This should be agreed in writing. The charger supplier, the backend provider, and the installer each have a role, and unclear responsibility is a common source of delay.
