Global Certification Speed
Our Kunshan testing laboratory conducts rigorous pre-compliance evaluations matching TÜV Rheinland, SGS, and UL benchmarks. Standard units undergo comprehensive testing for dielectric breakdown, temperature rise under sustained load, EMC emission, and salt spray corrosion before third-party sign-off.
Industrial Manufacturing Infrastructure at Scale
Public charging networks require mission-critical durability. Our manufacturing operations in Kunshan, adjacent to Shanghai, are architected to deliver reliability in diverse operating conditions. Field-deployed EV chargers must withstand environmental stress, from sub-zero conditions in Nordic winters to extreme ambient humidity and heat in Southeast Asia and the Middle East.
Our ODM development methodology emphasizes thermal management. By deploying CFD-modeled internal airflow chambers, independent cooling ducts for high-frequency resonant LLC converters, and IP55/IP65 ingress sealing, our systems avoid thermal derating even at ambient temperatures reaching 50°C. Galvanic isolation, comprehensive over/under-voltage mitigation, surge arresters, and leakage sensors ensure long operational lifecycles.

800V/1000V SiC Topologies
The industry shift toward 800V vehicle architectures requires wide-output chargers (150V–1000V DC). Utilizing Silicon Carbide (SiC) MOSFETs reduces switching losses, boosts module efficiency to 97%, and lowers cooling overhead.
Dynamic Matrix Power Routing
Split-type architectures dynamically allocate power in 20kW or 30kW increments across dispensing satellite guns. Power transfers seamlessly between vehicles without interrupting live charging sessions.
BESS Integrated Microgrids
Sites with constrained grid capacity leverage 100kWh–200kWh Lithium Iron Phosphate (LFP) energy storage units. These buffer power demand, reduce peak utility tariffs, and allow DC ultra-fast charging on 50kW grid drops.
ISO 15118 & Plug and Charge
Modern public installations require friction-free authorization. Native support for ISO 15118-2/20 enables encrypted automated handshakes, automated billing, and bidirectional vehicle-to-grid (V2G) power balancing.

Quality Assurance Protocols for Utility-Scale Procurement
Purchasing teams must mitigate field failure risks and long repair cycles. Our factory follows an IATF 16949-derived quality workflow across five manufacturing stages:
1. Component Validation: Critical active components—including microcontrollers, contactors, metering shunts, and power modules—are sourced from traceable suppliers. High-voltage DC contactors are tested to withstand 100,000+ electrical switching operations under load.
2. In-Line SMT Optical Inspection: Control and communication boards undergo automated Automated Optical Inspection (AOI) to eliminate solder bridging, component misalignment, and flux contamination.
3. High-Voltage Hipot Isolation Screening: Assembled units undergo dielectric withstand testing at 2,500V AC for 60 seconds to confirm complete galvanic isolation between primary power buses, chassis grounds, and sensitive secondary logic rails.
4. Full-Power Thermal Burn-In: Every finished charger is connected to an automated load bank and run at continuous rated power for 4 to 8 hours. Calibrated FLIR thermal sensors monitor busbar joints and module terminals to prevent field hot-spots.
Frequently Answered Technical Questions
Key technical insights addressing interoperability, field maintenance, grid limits, and operational certification.
Our units utilize a high-speed matrix relay or solid-state switching system managed by our internal MCU. When a single vehicle is connected, all internal power modules combine to deliver maximum power (e.g., 180kW). When a second vehicle connects, the controller reallocates modules based on vehicle BMS requests without terminating the active session.
The calculated MTBF of our integrated DC fast chargers exceeds 100,000 operational hours. Sub-assemblies use modular Field Replaceable Units (FRU). If a 30kW module flags an anomaly via OCPP diagnostics, the remaining modules continue operating while a replacement module is hot-swapped within minutes.
Yes. Our enclosures carry IP54 to IP55 ratings (with IP65 sealed electronic compartments). We use specialized internal PTC heating strips for cold climates to prevent condensation and keep electronics within operating limits down to -30°C. For hot regions, variable-speed EC fans and high-volume cooling prevent thermal derating up to 50°C.
The system combines a local high-density LFP battery pack with our DC fast charger. The battery charges continuously from modest grid feeds (e.g., 30kW to 50kW) or rooftop solar during low-demand periods. When an EV connects, both the grid feed and battery discharge together, delivering up to 160kW–200kW rapid charging without tripping local grid breakers.
We supply complete documentation dossiers for municipal and enterprise tenders, including CE Declaration of Conformity (LVD, EMC, RED), UL 2202 test certificates, CB test reports, ISO 9001/14001 factory audits, functional safety evaluations, and mechanical drawings.
Our firmware team runs ongoing interoperability validation against major international passenger and commercial EVs (Tesla, Volkswagen ID, Hyundai E-GMP, BYD, NIO, Geely, Volvo). We log PLC/CAN communication traces to ensure strict timing compliance with DIN 70121, ISO 15118, and SAE J1772 handshakes.
