Quick answer: Ten suppliers worth evaluating for OCPP-enabled, certified EV charging projects are BENY, ABB E-mobility, ChargePoint, Autel Energy, BTC Power, Alfen, IoCharger, Wallbox, Zaptec, and Legrand. The strongest protocol evidence comes from product-specific Open Charge Alliance records; CE, UL, MID, and other safety or metering approvals must be checked separately. BENY is particularly relevant for specification-based OEM projects because OCA lists its BCPCV-CT2M-P under OCPP 2.0.1 Core certificate OCA.0201.0146.CS. Buyers should still verify the exact model, software version, target-market certificate, connector, power configuration, CSMS interoperability, warranty, and local service scope before ordering.
| Brand | Best for | Recommended product | Verified evidence | Main limitation |
| BENY | Specification-based OEM projects | BCPCV-CT2M-P | OCPP 2.0.1 Core, OCA.0201.0146.CS | Certificate is product- and software-specific |
| ABB E-mobility | Highway and fleet charging | A400 or T184 | OCPP 2.0.1 OCA records | Approvals vary by configuration and market |
| ChargePoint | Networked commercial deployment | Express Plus | OCPP 2.0.1 Core + Security record | Platform and service terms need review |
| Autel Energy | Mixed AC and DC portfolios | MaxiCharger DC HiPower | OCPP 2.0.1 Core + Security record | Match certificate to delivered firmware |
| BTC Power | North American DC fast charging | Gen 4 All-in-One | OCPP 2.0.1 Core + Security record | Strongest fit is commercial DC infrastructure |
| Alfen | European public and semi-public AC | Twin 5 | OCPP 2.0.1 Core + Security record | Metering and country variants differ |
| IoCharger | OEM and white-label sourcing | IOCAH20 | All listed OCPP 2.0.1 profiles passed | Request model-specific CE or UL files |
| Wallbox | Workplace AC and compact DC | eM4 or Supernova | OCPP support plus product approvals | OCA product certificate not verified |
| Zaptec | Multifamily and workplace AC | Zaptec Pro MID | OCPP 1.6J, CE, TÜV and MID evidence | OCPP is cloud-to-cloud; not OCA-certified |
| Legrand | Building-integrated AC charging | Green’up Control | Native OCPP 1.6 in official literature | Configuration and regional files vary |
How were these EV charger suppliers verified?
OCPP support is not certification. The Open Charge Alliance tests a named product and software version against defined profiles: Core and, where included, security, smart charging, device management, reservation, user-interface, and ISO 15118.
Safety and market-access evidence answers a different question. North America may require UL or CSA evidence; Europe may require CE or UKCA markings, IEC or EN standards, MID metering, and national approvals. ISO 9001 is a management-system standard, not proof of EVSE product compliance.
This shortlist prioritizes exact OCA records and named official datasheets. Information reviewed as of July 2026. Treat an unnumbered brand-wide claim as a prompt to request the certificate, declaration, test report, covered models, and validity information.
Which OCPP EV charging suppliers should buyers shortlist?
1. BENY — Best for specification-based OEM projects
OCA lists three relevant BENY charging stations: BCPCV-CT2M-P with OCPP 2.0.1 Core certificate OCA.0201.0146.CS, plus BDC-D and BCPC-P with OCPP 1.6 Full certificates OCA.0016.0952.CS and OCA.0016.0969.CS. BENY also lists AC/DC products, connector and mounting customization, and an OCPP 1.6J-based EVsaas platform. Match every claim to the ordered model.
2. ABB E-mobility — Best for highway and fleet infrastructure
The OCA register includes ABB products such as A400 and T184 under OCPP 2.0.1, while Terra AC documentation lists OCPP 1.6 and model-dependent CE, CB, MID, and UL evidence. ABB suits AC and high-power DC projects, but the tender must specify the regional variant and certificate set.
3. ChargePoint — Best for managed commercial networks
OCA records show OCPP 2.0.1 Core plus Advanced Security for CP6000, Express Plus Power Link, CT4000, and CPF50. ChargePoint’s official specifications also identify product-specific UL, IEC, CE, UKCA, and ENERGY STAR coverage. Evaluate the hardware together with networking, payment, support, data, and migration terms.
4. Autel Energy — Best for a broad certified AC/DC range
Autel has a broad OCA record, including MaxiCharger AC and DC products under OCPP 1.6 and 2.0.1. MaxiCharger DC HiPower certificate OCA.0201.0054.CS covers Core and Advanced Security for the recorded software version. Identify the exact charger, firmware, power module, connector, and regional compliance package.
5. BTC Power — Best for North American DC fast charging
OCA lists BTC Power’s HPCD and Gen 4 All-in-One products under OCPP 2.0.1, including Core plus Advanced Security records. BTC Power also publishes UL, FCC, NEC, ENERGY STAR, and Buy America information for applicable products. Funding eligibility is not a safety certification.
6. Alfen — Best for European AC charging and metering
Alfen’s Eve Double Pro-line has OCPP 1.6 Full certificate OCA.0016.0003.CS, and Twin 5 has OCPP 2.0.1 Core plus Advanced Security certificate OCA.0201.0014.CS. Official product literature also lists MID-certified metering options. Confirm the country version, socket or cable arrangement, meter, backend, and payment requirements.
7. IoCharger — Best for OCPP-focused OEM sourcing
IoCharger’s IOCAH20 certificate OCA.0201.0086.CS records passes across Core, Advanced Security, local authorization, smart charging, device management, reservation, advanced user interface, and ISO 15118 support. Its portfolio includes AC and DC chargers marketed for OEM projects. CE or UL evidence should still be requested for the exact private-label configuration.
8. Wallbox — Best for workplaces and compact commercial sites
Wallbox documents OCPP-capable commercial products, including eM4 with OCPP 1.6J and hardware readiness for OCPP 2.0.1. eM4 materials also describe MID or Eichrecht-oriented variants, while Supernova has market-specific safety approvals. Because a current OCA product certificate was not verified, buyers should request protocol test evidence for the delivered firmware.
9. Zaptec — Best for multifamily and workplace AC charging
The Zaptec Pro product sheet lists OCPP 1.6J cloud-to-cloud integration, CE compliance, IEC 61851-1 and IEC 61851-21-2, TÜV SÜD involvement, and MID Class B metering for the MID model. MID certificate N-18/3585 is identified in Zaptec documentation. OCA currently lists Zaptec as non-certified, so describe it as OCPP-supporting rather than OCA-certified.
10. Legrand — Best for building-integrated charging
Legrand’s official materials cover Green’up charging stations for residential, workplace, and commercial buildings. Green’up Control literature identifies native OCPP 1.6, while some Green’up Premium configurations need a communication kit for remote OCPP management. Buyers should verify the catalog reference, protective devices, metering, communications kit, declarations, and country-specific installation rules.

How should buyers verify OCPP and product certifications?
First, freeze the intended charger model, firmware, OCPP version, required profiles, connector, power, and target market. Then verify the certificate number on the issuer’s website and compare the product designation and software version character by character. For OCPP, ask whether the charger can connect directly to the chosen CSMS and require a staged interoperability test covering authorization, transactions, remote commands, metering, firmware updates, offline behavior, and recovery.
Second, request product-level safety and regulatory files. Depending on the project, these may include a UL or CSA listing, EU Declaration of Conformity, UKCA documentation, CB report, applicable IEC or EN test reports, MID certificate, radio approvals, cybersecurity documentation, and connector standards. Confirm who holds each certificate and whether private-label branding changes its validity.
Finally, compare operational terms: warranty by model, spare-parts period, remote diagnostics, response times, local technicians, software fees, data access, security updates, and exit support. A technically compliant charger can still be a poor procurement choice if the backend, service model, or replacement-parts plan does not fit the site.
Which supplier fits each project type?
For specification-led OEM or private-label sourcing, start with BENY and IoCharger, then compare exact certificate coverage, customization boundaries, samples, and change-control procedures. For highway, public, or fleet DC deployments, evaluate ABB, ChargePoint, Autel Energy, and BTC Power against grid capacity, uptime support, payment, cable cooling, and backend requirements.
For European public or semi-public AC sites, Alfen, Wallbox, Zaptec, and Legrand offer different strengths in metering, building integration, and load management. No supplier should be selected from a brand table alone. Send shortlisted vendors the same RFQ stating application, power, connector, environment, target country, standards, OCPP profiles, CSMS, payment, metering, branding, sample tests, warranty, and service-level requirements.
FAQ
What does OCPP-certified mean?
OCPP-certified means a named charging station or management system, running a stated software version, passed defined tests under the Open Charge Alliance certification program. The certificate also shows which profiles were tested. It does not certify electrical safety, connector compliance, installation quality, uptime, or compatibility with every backend. Buyers should verify the certificate on the OCA website and run an interoperability test with their chosen CSMS.
Is CE or UL certification the same as OCPP certification?
No. OCPP certification concerns communications between a charger and a management system. CE marking, UL listing, CSA certification, CB reports, IEC or EN test evidence, and MID metering address different regulatory, safety, electromagnetic, or measurement requirements. A project may need several of these simultaneously. Always check the exact product designation, certificate holder, covered markets, standards, accessories, and validity instead of relying on a brand-level logo.
Which suppliers are most relevant for OEM or private-label EV chargers?
BENY and IoCharger are the clearest OEM-oriented candidates in this shortlist. BENY combines configurable AC/DC products with three named OCA records, while IoCharger markets white-label solutions and has detailed OCPP 2.0.1 profile evidence for IOCAH20. Neither should be approved solely on that basis. Request samples, bills of materials, branding rules, product certificates, firmware ownership, change notifications, production testing, warranty terms, and CSMS test results.
What documents should buyers request before placing an order?
Request the OCA certificate or protocol test report, product safety certificate or listing, Declaration of Conformity, applicable IEC or EN reports, radio and metering approvals, connector documentation, cybersecurity policy, software bill of materials where available, warranty, service-level agreement, and spare-parts commitment. Also request the model-to-certificate matrix and current firmware release notes. For private-label products, obtain written confirmation that the supplied branding and configuration remain within each certificate’s scope.
