Export projects should not assume GB/T vehicle compatibility outside China. |
| Japan | - CHAdeMO specifications for a large installed base of DC chargers
- JIS and local electrical safety requirements
- Vehicle and site communication requirements defined by the selected charging system
| CHAdeMO remains important for many public installations. The connector strategy should follow the local vehicle mix and procurement specification. | Approximately 25–90 kW is common for many existing and replacement sites; site-specific projects may use higher power. | Commercial sites may use three-phase AC service, while smaller sites can have different supply arrangements depending on the equipment and utility connection. | Seismic design review where applicable, weather protection, grounding, leakage protection, emergency stop, cable storage, snow or water management, site-access planning, and local utility approval. | A durable CHAdeMO-focused charger is suitable where the installed vehicle base requires it. For new projects, confirm whether a multi-standard solution is justified by local demand. |
| South Korea | - National electrical safety and charging-infrastructure requirements
- Vehicle communication requirements applicable to the selected charging system
- Local fire, construction, accessibility, and utility regulations
| CCS Combo 1 is widely used for public DC charging. Some legacy vehicles and sites may require additional connector support. | Approximately 50–180 kW for many public installations, with higher power available at selected highway sites. | Typically 380 V three-phase AC for commercial charging stations. | Electrical safety certification, grounding, insulation and leakage protection, surge protection, weather resistance, emergency isolation, fire-safety review, and sufficient parking-bay clearance. | A CCS1 charger with a high-efficiency power module and strong thermal management is a practical choice for public and fleet applications. |
| India | - National guidelines for electric-vehicle charging infrastructure
- IEC-aligned requirements adopted through Indian standards where applicable
- CCS2 is widely specified for public DC fast charging
- State electricity-board, fire, building, and metering requirements
| CCS Combo 2 for most new public DC fast-charging projects. Legacy low-power systems may use other national configurations. | Approximately 30–180 kW, depending on vehicle demand, highway usage, and available grid capacity. | Usually 415 V three-phase AC for commercial installations, subject to local distribution availability. | Heat and dust protection, ventilation, earthing, residual-current protection, surge protection, lightning protection where required, fire-safety equipment, remote monitoring, and reliable backup or power-quality planning. | A CCS2 charger rated around 60–120 kW is suitable for many urban and fleet sites. Higher power should be selected only after checking transformer capacity and operating temperature. |
| Australia and New Zealand | - IEC 61851 and IEC 62196 principles
- AS/NZS 3000 wiring rules and related electrical installation requirements
- Local rules for metering, accessibility, construction, and network connection
| CCS Combo 2 is the predominant public DC connector. CHAdeMO may be retained where legacy vehicle support is required. | Approximately 50–180 kW for common sites; 300 kW-class equipment may be used on selected highway corridors. | Commonly 400 V three-phase AC for commercial sites. | Compliance with wiring rules, switchboard capacity, earthing, residual-current protection, surge protection, UV and weather resistance, accessibility, cable protection, and local distribution-network approval. | A CCS2 charger with robust outdoor protection and flexible load management is generally the most future-ready option. Retain a second connector only when local demand supports it. |
| Middle East and Africa | - IEC 61851 and IEC 62196 are commonly referenced
- National electrical codes and utility connection rules vary significantly
- Project specifications may require additional civil-defense or fire-safety approvals
| CCS Combo 2 is common in many newer projects, while CCS Combo 1, CHAdeMO, or GB/T may be required for specific fleets. | Approximately 60–180 kW for public sites; higher power is possible where grid infrastructure and vehicle demand permit. | Often 400/415 V three-phase AC, but voltage, frequency, and service capacity must be verified for each country and site. | High-ambient-temperature derating, dust and sand protection, solar exposure management, air-conditioning or liquid cooling where necessary, surge and lightning protection, earthing, fire-safety clearance, and utility approval. | A CCS2 charger with wide operating-temperature capability, strong ingress protection, and active thermal management is a suitable default for many new projects. |
| Multi-Regional or Export Projects | - IEC 61851 and IEC 62196 provide a common international reference
- Connector and communication compliance must still be verified for each destination
- Local certification, metering, cybersecurity, and radio-communications rules may apply
| Use region-specific CCS2, CCS1, SAE J3400, GB/T, or CHAdeMO versions rather than relying on mechanical adapters as the primary solution. | 60–180 kW is a versatile international range; 240–350 kW should be reserved for sites with suitable vehicles and grid capacity. | A configurable 400–480 V three-phase input platform can simplify deployment, but the input voltage, frequency, protection, and certification must be adapted to each market. | Confirm local electrical code, grid interconnection, environmental rating, electromagnetic compatibility, payment and communications rules, civil works, accessibility, and spare-parts support before shipment. | The best global platform is a modular charger with replaceable power units, configurable output voltage, remote diagnostics, open network communication, regional connector options, and documented local certification. |
