■ Global Procurement Demand & Logic

The global demand for AC/DC charging components is shifting from "commodity hardware" to "integrated systems." International buyers from North America and Europe are prioritizing Total Cost of Ownership (TCO), which includes not just the unit price, but the integration compatibility, thermal efficiency, and long-term reliability of power electronics.

Shenzhen DCI Autos Co., Ltd., established in 2014, addresses these demands by providing end-to-end solutions. Located in the heart of Shenzhen's innovation hub, we leverage a supply chain that responds 3x faster than traditional Western alternatives.

■ Compliance & Localization Support

Navigating global grid codes requires more than just a standard product. Our engineering team provides localized support for:

CE/TUV/UL Certification: Ensuring all AC/DC modules meet strict safety standards for specific regions.
Grid Harmonization: Compliance with IEEE 1547 and local utility requirements for harmonic distortion and power factor.
Cybersecurity: Implementing OCPP 2.0.1 for secure cloud-to-charger communication.

■ Technical Roadmap 2025-2030

Our R&D direction focuses on three pillars of Information Gain for our clients:

Modular Power Units: Swapable power modules (15kW to 40kW) that allow for easy maintenance and future capacity upgrades.
Liquid-Cooled Terminals: Achieving 600A+ charging current without cable overheating, essential for heavy-duty commercial EVs.
Solid-State Compatibility: Developing BMS and charging protocols ready for the next generation of solid-state battery chemistries.
