| Maximum DC Charging Power | 250 kW continuous rated output | Suitable for highway and fleet applications requiring high charging throughput. A 250 kW rating is a product capability, not a standalone international charging standard. | Published data sheet, rated-output test report, and operating-temperature performance data. | Essential |
| DC Output Voltage Range | 200–1,000 V DC | Broad voltage coverage supports passenger EVs, commercial vehicles, and both lower-voltage and 800 V vehicle platforms. | Electrical specification showing minimum and maximum regulated output voltage. | Essential |
| DC Output Current | At least 312.5 A at 800 V | 250 kW ÷ 800 V = 312.5 A. At 500 V, approximately 500 A is required to deliver the same power, subject to connector and thermal limits. | Current-versus-voltage power curve and connector thermal derating chart. | Essential |
| Dynamic Power Sharing | Yes, cabinet-level or site-level allocation | Power should be allocated dynamically among multiple charging dispensers while respecting the site import limit and each vehicle’s charging request. | Demonstration test showing load balancing, power ramping, and recovery after a session ends. | High |
| Peak Efficiency | At least 95% at high-load operation | Higher conversion efficiency reduces energy losses, operating cost, and thermal stress. The exact result depends on input voltage, load, temperature, and power factor. | Efficiency curve measured at multiple load points, including approximately 50%, 75%, and 100% load. | High |
| Input Power Quality | Three-phase AC input with power factor near unity | High-power DC chargers generally use three-phase AC supply. High power factor and controlled harmonics help reduce grid impact. | Power-factor and total-harmonic-distortion measurements under representative operating loads. | High |
| Charging Interface Coverage | Regional connector compliance | Common interfaces include CCS Type 1, CCS Type 2, SAE J3400, and GB/T DC, depending on market and vehicle fleet. Connector selection must match local regulations and vehicle compatibility. | Applicable regional certification, connector specification, and vehicle interoperability test results. | Essential |
| OCPP Version | OCPP 2.0.1 support | OCPP 2.0.1 provides expanded device management, transaction handling, smart charging, security features, monitoring, and improved extensibility compared with earlier versions. | OCPP 2.0.1 conformance evidence, supported profile list, and successful central-system interoperability test. | Essential |
| OCPP Security | Encrypted communication and certificate-based security | Secure Transport Layer communication, controlled credential management, signed firmware, and role-based access reduce cyber-security risks. | Security profile documentation, certificate lifecycle procedure, penetration-test summary, and firmware-signing process. | Essential |
| ISO 15118 Communication | ISO 15118-2 readiness; ISO 15118-20 roadmap or support | ISO 15118 enables advanced vehicle-to-charger communication, including automated identification, charging parameter negotiation, and Plug & Charge use cases where supported by the vehicle, contract, backend, and certificates. | ISO 15118 interoperability test, supported use-case list, certificate-chain documentation, and vehicle compatibility matrix. | Essential |
| Plug & Charge | Production-ready implementation, not only a software option | Plug & Charge requires coordinated support from the vehicle, charging station, backend system, contract certificate, and certificate provisioning service. | End-to-end session test covering certificate installation, authorization, charging, billing, and certificate revocation. | High |
| Interoperability Testing | Multi-vendor backend and vehicle validation | Protocol compliance alone does not guarantee stable operation with every vehicle or charging-management platform. | Documented test matrix covering multiple vehicles, backend platforms, interrupted sessions, offline operation, and firmware updates. | Essential |
| Operating Temperature | Approximately −30°C to +50°C design range | Actual rated power may be reduced at extreme temperatures. Thermal management and derating behavior are important for outdoor and high-throughput sites. | Environmental test report and power-derating curve across the declared temperature range. | High |
| Ingress and Impact Protection | Outdoor enclosure protection appropriate to site conditions | Outdoor equipment commonly requires protection against dust, water, condensation, and mechanical impact. The correct rating depends on cabinet location and local code. | Independent enclosure test report, installation manual, and evidence of compliance with applicable regional requirements. | High |
| Reliability and Availability | Target availability of at least 98% | Availability should be calculated transparently and should distinguish charger faults, communications failures, grid outages, planned maintenance, and vehicle-side issues. | Service-level methodology, historical operational data, fault logs, and maintenance response-time commitments. | Essential |
| Remote Diagnostics and Updates | Secure remote monitoring and controlled firmware updates | Remote diagnostics reduce service visits and support lifecycle management. Updates should preserve configuration, maintain rollback capability, and be authenticated. | Operations-platform demonstration, update policy, rollback procedure, audit logs, and cybersecurity documentation. | High |
| Metrology and Billing Data | Traceable energy measurement suitable for local regulation | Energy measurement, timestamps, transaction records, and tariff data must support accurate billing and regulatory reporting. | Meter accuracy documentation, calibration records, transaction-data format, and local legal-metrology approval where required. | Essential |
| Sustainability and Serviceability | Modular power electronics and replaceable wear components | Modular architecture can reduce repair time and extend service life. Cable, connector, cooling, surge-protection, and power modules should be serviceable. | Spare-parts list, mean-time-to-repair target, maintenance manual, warranty terms, and end-of-life recycling policy. | Medium |
