OCPP 2.0.1 DC Checklist
For operator projects, backend testing is a procurement step, not an afterthought after shipment.
Project configuration
Treat backend acceptance as part of charger procurement
An OCPP EV charger supplier should confirm the protocol version by exact charger model and firmware, then test the target CSMS connection before a batch order. The RFQ should define backend URL, charger identity, security profile, network method, authorization, meter values, remote commands, alarms, firmware actions, payment flow and reporting; support is confirmed per model/project.
Protocol scope
Confirm OCPP 1.6J, OCPP 2.0.1 or both for the exact charger and firmware.
CSMS acceptance
Provide backend URL or test account, charger identity rules, security profile and acceptance-test list.
Operating functions
Define authorization, start and stop, meter values, alarms, reset, firmware actions, reports and user roles.
Payment and ownership
Clarify RFID, app, QR or POS flow and whether the CSMS, gateway, operator or charger owns each responsibility.
Continue project planning
OCPP Charger Integration
Confirm OCPP 1.6J or 2.0.1 requirements, charger model scope, backend URL setup and connection testing before batch supply.
CSMS Operation Scope
Manage chargers, sites, users, tariffs, alerts, sessions and reporting through an operator-ready charging management workflow.
Payment & Access
Review RFID, app, QR, POS, user account, fleet card and paid public charging requirements before confirming the software scope.

Use this checklist before asking an OCPP software supplier or EV charger manufacturer for a quotation.
| Topic | What to Confirm | Why It Matters |
|---|---|---|
| OCPP version | OCPP 1.6J, OCPP 2.0.1 or both; confirm version by exact charger model and firmware. | Commercial networks need stable backend communication, not only a protocol label. |
| CSMS connection | Backend URL, charger identity, security profile, certificates, test account and acceptance test plan. | Reduces integration risk before importers or CPOs commit to a batch order. |
| Operation workflow | Remote start/stop, authorization, meter values, alarms, remote reset, firmware actions and reporting. | These functions decide whether the charger can be operated after installation. |
| Payment and users | RFID, app account, QR code, POS, fleet card, tariff plan, receipts and transaction export. | Payment and access rules differ for fleet, parking, mall and public charging sites. |
| Data and API | Site hierarchy, user roles, energy reports, session exports, API needs and white-label dashboard scope. | Important for distributors, OEM brands and multi-site charging operators. |
OCPP hardware, CSMS and operating-function acceptance matrix
Record the exact charger model, firmware, protocol version, target CSMS and test date. A protocol label alone does not confirm that the required operating workflow has passed end-to-end testing.
| Acceptance area | Charger or firmware scope | CSMS or third-party scope | Evidence before batch approval |
|---|---|---|---|
| Connection and identity | Endpoint settings, charger identity, firmware and reconnect behavior. | Device registration, endpoint access and identity rules. | Dated connection log for the quoted charger and target CSMS. |
| Authorization and sessions | Connector status, authorization handling, transaction start/stop and meter values. | User or RFID records, tariff logic, session records and operator controls. | Agreed test cases with results for required transaction flows. |
| Remote operation | Remote commands, reset behavior, charging profiles and fault reporting supported by the selected firmware. | Command interface, permissions, alerts and audit trail. | Command and alarm records showing expected and failed-case behavior. |
| Payment and access | Charger-side reader, display, QR or terminal interface where included. | Payment gateway, app, tariff, receipt, settlement and account responsibilities. | Documented payment path and responsible system for each step. |
| Load management | Charger response to power limits and safe behavior after communication loss. | Site limit, allocation rules, meter or CT input and priority logic. | Load-allocation test using the planned controller or CSMS. |
| Acceptance closeout | Final model, firmware, configuration export and shipment setting. | Production environment, user roles, reporting and support handover. | Signed acceptance record plus retained logs and configuration versions. |
For fleet depots
Prioritize charger uptime, schedule windows, load management, driver authorization and energy reports.
For public charging
Prioritize payment, tariff rules, availability display, fault alerts and transaction records.
For distributors
Prioritize tested charger models, repeatable firmware settings, white-label scope and support handover.

FAQ
OCPP EV Charger and CSMS FAQ
Short answers for buyers comparing OCPP-ready AC/DC chargers, CSMS integration, payment workflow and operator testing.
What is OCPP in EV charging?
OCPP is the communication protocol between EV chargers and a charging management platform. It supports remote monitoring, authorization, billing, fault reporting, firmware actions and charging-session data.
What is a CSMS platform for EV charging?
A CSMS is a charging station management system used by operators to manage chargers, users, tariffs, payments, sessions, alarms, firmware and reporting across one or many charging sites.
Should buyers choose OCPP 1.6J or OCPP 2.0.1?
OCPP 1.6J is widely used and practical for many commercial networks. OCPP 2.0.1 is better for newer projects that need stronger device management, security and future-ready smart charging functions.
What should buyers test before importing OCPP EV chargers?
Test charger connection, authorization, start/stop transaction, meter values, fault alarms, remote reset, firmware actions, payment flow and reporting with the target CSMS before batch orders.
What information should an OCPP charger RFQ include?
Send charger type, power rating, connector standard, target OCPP version, CSMS provider, backend URL or test account, security profile, network method, payment workflow, quantity, market and certification needs.
Can the target CSMS be reviewed before shipment?
Provide the target CSMS, available test access, charger identity rules and acceptance criteria. Feasibility, supported checks and responsibilities are confirmed for the selected charger model and project before any test commitment.
Should payment functions be handled by the charger or by the CSMS?
Payment scope depends on the project. Some sites use RFID or app authorization through the CSMS; public charging sites may also need QR, POS, tariff rules, receipts and settlement reports.
Does the supplier provide a CSMS, or integrate chargers with the buyer's CSMS?
This must be defined in the RFQ. A project may use the buyer's existing CSMS, a third-party platform or a separately agreed platform scope. Confirm platform ownership, charger and firmware compatibility, test access, required functions, data ownership and ongoing support before placing a batch order.

EV Charging Station Management Software Must Match the Operator Workflow
EV charging station management software should be evaluated against actual user authorization, tariffs, payments, charger groups, alarms, firmware, reporting and support ownership. A protocol label alone does not prove that the required end-to-end workflow has been tested.
EV charging load management acceptance
An EV charging load management test should show how power is allocated when vehicles connect, disconnect, reach a target or become unavailable, including what the operator can see in the platform.
EV charger load management system boundary
Define whether the EV charger load management system logic sits in a local controller, the charger network, the CSMS or a combination, and assign ownership for configuration and fault diagnosis.
