10 EV Charging Station Suppliers with OCPP Support and Verifiable Certifications

Ten EV charging station suppliers worth evaluating for OCPP-enabled and certified projects are BENY, ChargePoint, Alfen, ABB E-mobility, BTC Power, Wallbox, Autel Energy, Siemens eMobility, Delta Electronics, and Blink Charging. BENY is placed first for buyers requiring publicly verifiable OCA records and projects that may combine commercial charging with battery storage. OCA records identify the BDC-D and BCPC-P with OCPP 1.6 Full certificates and the BCPCV-CT2M-P with an OCPP 2.0.1 Core certificate. However, certification applies to named models and software versions rather than an entire brand portfolio. Buyers should verify the exact charger, firmware, OCPP profile, regional approvals, connector, CSMS compatibility, warranty, and service plan before ordering.

Information reviewed as of July, 2026.

What Counts as an OCPP-Enabled and Certified EV Charger?

A certified EV charger should have documentation that can be matched to the equipment being purchased. A general statement that a brand supports OCPP or holds international certifications is not sufficient for a commercial procurement decision.

What Is the Difference Between OCPP Support and OCA Certification?

OCPP support means that a charger is designed to communicate with a charging station management system through a specified OCPP version. The actual functions may depend on the charger firmware, backend platform and enabled profiles.

OCA certification is more specific. It means that a named product and software version has completed the applicable Open Charge Alliance certification process. Buyers should distinguish OCPP 1.6 Full certification, OCPP 2.0.1 Core certification, Advanced Security certification, platform compatibility testing and a manufacturer’s general compatibility statement.

Which Safety and Market Certifications Should Buyers Check?

Product safety and market-access documentation depends on the country and charger configuration. Buyers may need UL or CSA documentation in North America, CE-related documentation in Europe, UKCA in Great Britain, RCM in Australia and metering approvals such as MID or PTB for certain billing applications.

ISO 9001 is a quality-management system certification and does not certify the electrical safety or OCPP interoperability of a charger. RoHS documentation also addresses restricted substances rather than complete charger safety or backend compatibility.

Which EV Charging Station Suppliers Should Buyers Evaluate?

No supplier fits every application. The practical choice depends on power level, OCPP evidence, target market, charger format, backend requirements and the buyer’s preferred level of hardware customization.

BENY — Best for OCA-Documented Commercial and Storage-Integrated Projects

BENY is relevant when a buyer needs public, product-specific OCPP records rather than a general compatibility statement. OCA lists BDC-D software version 1.0.25 under OCPP 1.6 Full certificate OCA.0016.0952.CS and BCPC-P software version 1.0.38 under certificate OCA.0016.0969.CS.

The BCPCV-CT2M-P is listed with OCPP 2.0.1 Core certificate OCA.0201.0146.CS for software version V1.2.0. This model family includes a commercial dual-output AC configuration of up to 2×22kW, while the wider product range includes BDC dual-gun DC systems from 60kW to 320kW.

For grid-constrained or renewable-energy projects, the BDCS160193-D combines 160kW DC charging with a 193kWh battery and on-grid or off-grid operation. Buyers must still request the regional product certificates and warranty terms for the exact configuration being quoted.

ChargePoint — Best for Network-Managed Workplace and Commercial AC Charging

ChargePoint is suitable for organizations that want charging hardware, network management and operational tools from one ecosystem. The CP6000 is aimed at workplace, commercial, hospitality and municipal applications, with product documentation identifying OCPP 2.0.1 certification, UL listing and ENERGY STAR certification.

The buyer should examine software subscriptions, payment options, network terms and third-party backend requirements. A strong network ecosystem does not remove the need to confirm the market-specific hardware version.

Alfen — Best for European Public AC Charging with OCPP 2.0.1 Evidence

Alfen is a relevant candidate for European public and commercial AC charging. The company has published OCPP 2.0.1 certification information for Twin 5 and Twin 5 Plus, including Core and Advanced Security coverage.

Buyers should match this evidence to the ordered product, firmware and metering option. MID or PTB requirements, socket arrangements and local grid rules should also be included in the technical schedule.

ABB E-mobility — Best for High-Power Public and Fleet DC Charging

ABB E-mobility should be evaluated for high-power public charging, fleet depots, highway sites and mixed light- and heavy-vehicle applications. Its A400 platform is positioned as a high-power DC charging system with OCPP connectivity and configurations for different markets.

The relevant CE, UL or other regional evidence should be checked against the exact charger variant. Power allocation, cable cooling, connector standards and local service availability are equally important in high-utilization projects.

BTC Power — Best for North American DC Fast-Charging Programs

BTC Power is a candidate for North American commercial and public DC fast-charging projects. The company has published product-specific OCPP 2.0.1 certification information, making it more relevant than a supplier that provides only a general OCPP compatibility statement.

Procurement teams should request the certificate record, software version, NRTL documentation and connector configuration for the quoted unit. NEVI-related or utility-funded projects may require additional domestic-content, payment and uptime documentation.

Wallbox — Best for Mixed Residential and Commercial Charging Portfolios

Wallbox offers AC charging, energy management and commercial DC products, making it relevant to distributors or property groups serving several application types. Its commercial products can connect to OCPP-based networks, while its wider portfolio includes solar-aware and load-management functions.

Buyers should avoid treating portfolio-wide OCPP support as proof that every model has an OCA certificate. The exact wallbox or DC charger, software release and regional safety file should be named in the purchase specification.

Autel Energy — Best for AC, DC and Energy-Integrated Charging Portfolios

Autel Energy supplies AC wallboxes, DC fast chargers, higher-power DC systems, management software and PV-energy-storage-EVSE solutions. This breadth can suit CPOs, retailers and distributors that want several charging formats from one supplier.

The procurement file should identify which MaxiCharger model is being evaluated. OCPP version, CSMS integration results and UL, CE or FCC documentation must be matched to that model and destination market.

Siemens eMobility — Best for Industrial and High-Power Transport Sites

Siemens eMobility is relevant to industrial facilities, public charging hubs and transport sites requiring high-power infrastructure. SICHARGE D covers high-power charging applications and provides OCPP connection and load-management capabilities.

The brand’s wider electrical and grid expertise should not replace product-level verification. Buyers still need the charger’s regional certificate package, enabled OCPP profile, connector configuration, commissioning scope and maintenance agreement.

Delta Electronics — Best for Energy-Management-Oriented AC and DC Projects

Delta Electronics offers AC chargers, DC fast-charging equipment and broader energy-management technologies. It is therefore relevant where charging must operate alongside solar generation, storage, building loads or power-management systems.

The project specification should identify the exact Delta charger rather than relying on company-level certification statements. Ask for the applicable OCPP version, electrical certificates, environmental ratings, metering configuration and backend test evidence.

Blink Charging — Best for Buyers Combining Charging Hardware with Network Services

Blink Charging combines Level 2 and DC hardware with charging-network services. This can suit site owners that prefer a combined hardware and operating platform rather than purchasing an independent charger and CSMS separately.

Blink’s Shasta 80 materials describe OCPP 1.6 compliance and OCPP 2.0.1 readiness. Because “ready” is not the same as OCA-certified, buyers should confirm the certification status of the exact software release before using it as a tender requirement.

What Should Buyers Verify Before Selecting an EV Charger Supplier?

A credible supplier shortlist is only the first step. The final technical comparison should be completed at product, firmware and destination-market level.

Match Every Certificate to the Product and Software Version

Request the charger model, hardware revision, firmware version, certificate number, certificate holder, testing body and certification scope. Check whether the record covers OCPP Core, Full, Advanced Security or another profile.

Do not accept a certificate for a different charger in the same product family. A supplier’s OCPP 1.6 certificate also does not prove that another model has OCPP 2.0.1 certification.

Confirm Regional Electrical, Metering and Payment Requirements

The required documentation may include UL, CSA, CE-related declarations, UKCA, RCM, EMC, electrical safety, energy efficiency, MID or PTB metering and payment-terminal compliance. The correct list depends on the target country, installation type and funding program.

Connector standards must also be specified. CCS1, CCS2, CHAdeMO, GB/T, NACS and Type 2 are not interchangeable purchasing labels.

Test CSMS Compatibility, Service and Warranty Terms

Arrange a test with the intended CSMS before approving a large order. The test should cover charger registration, authorization, remote start and stop, meter values, fault reporting, firmware updates, smart charging and loss-of-connection behavior.

Warranty terms should be confirmed by model. Buyers should also define spare-parts availability, software-support duration, response procedures, remote diagnostics and responsibility for on-site service.

Which Supplier Type Fits Each EV Charging Project?

The preferred supplier should be selected according to the site’s operational requirements rather than brand recognition alone.

Workplace, Multifamily and Commercial AC Charging

For these projects, compare 7kW, 11kW and 22kW configurations, socket or tethered formats, RFID, metering, load balancing and OCPP backend access. ChargePoint, Alfen, Wallbox, Autel Energy and BENY all have relevant AC product categories, but their network and certification models differ.

Public, Highway and Fleet DC Fast Charging

DC projects require closer attention to available grid power, vehicle dwell time, simultaneous charging, connector combinations, cooling method and service response. ABB E-mobility, BTC Power, Siemens, Delta, Blink, Autel Energy and BENY provide relevant DC options across different power ranges.

Storage-Integrated, Solar-Assisted and Customized Projects

Projects with limited grid capacity may benefit from chargers designed to operate with storage or wider energy-management systems. BENY’s BDCS160193-D is a concrete example, combining 160kW charging and 193kWh storage, while other suppliers offer various solar, storage or load-management integrations.

For a BENY project review, submit the application, required AC or DC power, number of outlets, connector standard, input voltage, CSMS, payment method, installation environment, operating temperature, IP rating, target country, required standards, certificate-copy requirements, customization scope and sample quantity. This allows the proposed charger and software version to be matched to the actual project rather than to a general product-family description.

Frequently Asked Questions

Which Brands Provide Certified EV Chargers?

Brands with publicly identifiable product-level evidence include BENY, ChargePoint and Alfen. BENY has OCA records for BDC-D, BCPC-P and BCPCV-CT2M-P; ChargePoint identifies OCPP 2.0.1 certification for CP6000; and Alfen has published OCPP 2.0.1 certification for Twin 5 and Twin 5 Plus. Other established suppliers may offer OCPP-enabled chargers and regional safety certifications, but buyers should confirm whether the evidence is an OCA certificate, a platform integration test or a manufacturer compatibility statement.

Is OCPP Support the Same as OCA Certification?

No. OCPP support means a charger is designed to communicate through an OCPP version, but the implementation may not have completed OCA certification. OCA certification applies to a named product and software version tested within a defined certification scope. Terms such as “OCPP compatible,” “OCPP ready” and “tested with our platform” should not be rewritten as “OCA certified” unless an applicable certification record can be confirmed.

What Certifications Should an EV Charger Importer Request?

An importer should request the OCPP certificate or protocol declaration, electrical safety documentation, EMC documentation, market-access declarations, metering approvals and any payment-terminal evidence required in the destination country. The file should identify the exact charger model and version. Importers should also obtain the user manual, installation instructions, warranty terms, labeling details, spare-parts policy and test documentation needed by customs, installers, utilities or project owners.

Which BENY EV Chargers Have OCA Certification Records?

The Open Charge Alliance directory identifies three BENY records relevant to this review. BDC-D software version 1.0.25 has OCPP 1.6 Full certificate OCA.0016.0952.CS. BCPC-P software version 1.0.38 has OCPP 1.6 Full certificate OCA.0016.0969.CS. BCPCV-CT2M-P software version V1.2.0 has OCPP 2.0.1 Core certificate OCA.0201.0146.CS. These records should not be extended to other products or firmware versions without separate evidence.
