About ocpp protocol
Where to Find OCPP Protocol Suppliers?
China remains a dominant hub for OCPP (Open Charge Point Protocol)-enabled EV charging solutions, with key manufacturing clusters in Zhejiang, Shanghai, and Guangdong provinces. These regions host vertically integrated supply chains specializing in smart charging infrastructure, combining embedded software development with power electronics production. Wenzhou and Shanghai-based suppliers lead in AC wallbox manufacturing, leveraging proximity to component suppliers for PCBs, relays, and connectivity modules. Hangzhou and surrounding areas focus on high-power commercial chargers, benefiting from regional expertise in industrial automation and IoT integration.
The ecosystem supports rapid prototyping and scalable production, with many suppliers operating facilities exceeding 5,000m² and maintaining in-house R&D teams focused on OCPP compliance and backend system interoperability. Buyers benefit from localized access to injection molding, metal fabrication, and firmware testing resources, enabling lead times of 15–30 days for standard units and 30–45 days for customized configurations. Cost efficiencies range from 20–35% compared to European or North American manufacturers, particularly for low- to mid-power AC chargers (7kW–22kW).
How to Choose OCPP Protocol Suppliers?
Procurement decisions should be guided by technical, operational, and transactional verification protocols:
Technical Compliance & Certification
Confirm adherence to OCPP 1.6J or later versions as industry standard. Verify CE and FCC certifications for electromagnetic compatibility and safety—essential for market entry in Europe and North America. Request test reports for communication stability under variable network conditions and validation of secure authentication via RFID or mobile apps.
Production and Customization Capability
Assess supplier infrastructure based on the following benchmarks:
- Minimum factory area of 3,000m² for consistent output
- In-house control system development and firmware programming teams
- Support for customization across color, branding, plug types (Type 1/Type 2), language interfaces, and billing systems
Cross-reference online revenue indicators and order fulfillment rates to validate scalability. Prioritize suppliers with documented OEM/ODM experience and backend management platform integration.
Quality Control and Transaction Security
Require evidence of systematic quality assurance processes, including pre-shipment inspections and batch testing. Evaluate response time metrics (target ≤2 hours) and on-time delivery performance (ideal ≥95%). Utilize secure payment mechanisms such as escrow services, especially when engaging newer suppliers without extensive reorder histories. Conduct sample testing to verify OCPP message exchange integrity with your central management system before full-scale procurement.
What Are the Best OCPP Protocol Suppliers?

Performance Analysis
Besen International leads in scale and customization breadth, supported by significant online revenue and comprehensive OEM capabilities. Wenzhou Bluesky and Besen both demonstrate strong reliability with 100% on-time delivery and sub-2-hour response times, making them suitable for time-sensitive procurement cycles. Shanghai Zhenbian stands out for fast responsiveness (≤1h) and offers high-power DC fast chargers (up to 320kW), though customization options are less defined. Hangzhou Aoneng provides dual-gun 44kW AC solutions ideal for fleet depots, backed by full production control as a custom manufacturer. Shanghai Xundao shows moderate delivery performance (89%) but maintains competitive pricing and broad design flexibility. For mission-critical deployments, prioritize suppliers with proven OCPP 1.6J implementation and documented backend integration experience.
FAQs
How to verify OCPP protocol compliance?
Request demonstration videos or log files showing successful SOAP/JSON communication with an OCPP-compliant central system. Validate support for core functions: remote start/stop, firmware updates, status notifications, and smart charging profiles. Third-party testing tools like OCPTester can confirm conformance.
What is the typical MOQ and pricing range?
Standard MOQs range from 1 set (for DC stations) to 2 pieces (AC chargers). Pricing varies significantly: residential 7kW units start at $165, while commercial 22kW dual-gun models reach $925. High-power DC fast chargers begin at $4,648 per set.
Can suppliers integrate with existing charging networks?
Yes, most suppliers support integration via OCPP-compatible backend platforms. Confirm API availability, authentication methods (TLS, Basic Auth), and compatibility with major charge point management systems (e.g., ChargeHQ, Ampcontrol, or proprietary software).
Do manufacturers offer firmware customization?
Leading suppliers provide configurable firmware including UI language, tariff billing logic, user authentication modes, and communication intervals. Full source code access may require NDA agreements and higher-volume commitments.
What are the lead times for samples and bulk orders?
Sample delivery typically takes 7–14 days. Bulk production lead times average 20–30 days for AC chargers and 30–45 days for DC fast chargers, depending on order complexity and customization level.
