Dongguan Caiku Electronic Technology Co. Ltd. is a premier high-tech enterprise specialized in producing world-class power adapters, high-voltage car chargers, electric vehicle (EV) charging stations, and high-frequency semiconductor components. Since our establishment in 2011, we have executed two comprehensive strategic and manufacturing upgrades. Today, Caiku operates as a large-scale integrated technology enterprise combining proprietary semiconductor innovation with precision automotive electronics manufacturing.
Caiku promises uncompromised quality control, strict zero-defect manufacturing protocols, and responsive B2B service for global automotive suppliers and importers.
Backed by over 20 structural and electrical patents across Europe, North America, and China, leading the frontier of high-frequency power switching.
Successfully commercialized across more than 100 countries and regions worldwide, delivering operational longevity under diverse grid standards and extreme climates.
Our dedicated engineering team releases 3 to 10 new high-efficiency power products monthly, reducing time-to-market for custom client configurations.
Analyzing Next-Generation Power Architectures: GaN, Super Si MOSFETs, Liquid-Cooled OBC Modules, and Mega-Watt Ultra Fast Charging Infrastructure.
As the automotive sector transitions from traditional 12V auxiliary power systems toward high-voltage 400V/800V EV architectures, car charger engineering demands extreme power density, ultra-high switching frequencies, and zero-compromise thermal protection. Dongguan Caiku Electronic Technology Co. Ltd. sits at the intersection of chip-level component innovation and automotive system integration.
| Architecture & Topology | Primary Component / IC | Efficiency Rating | Thermal Dissipation Strategy | Target Application Segment |
|---|---|---|---|---|
| Super Si (Super Silicon) DC-DC | Oss65r340df / Oss65r340FF MOSFET | 94.5% - 96.0% | High Thermal Conductivity Epoxy & Aluminum Heatsinks | In-Car Fast Power Delivery (PD 65W-100W), Compact Adapters |
| Gallium Nitride (GaN Fast Charge) | GaN Fast Switching Power IC | 96.5% - 98.2% | 3D Copper PCB Stacking & Graphene Thermal Pads | Multi-Port High-Wattage In-Vehicle Power Stations, Laptop Chargers |
| Liquid-Cooled On-Board Charger (OBC) | 6.6kW Dual-Directional OBC Module | 95.8% Peak | Active Liquid Cooling Circuit (Ethylene Glycol Loop) | Passenger EVs, Plug-in Hybrids (PHEV), Commercial E-Buses |
| Ultra-Fast DC Charging Station | 30kW - 600kW Split Modular Power Cabinets | 97.0%+ System Level | Forced Air Channeling & Liquid Cooled Cable Guns | Highway Supercharging Hubs, Commercial Logistics Fleets |
Our proprietary Super Si MOSFETs (such as the Oss65r340df TO252 and Oss65r340FF TO220F series) deliver up to 1/3 the cost of conventional GaN devices while maintaining exceptional high-frequency operation. This provides B2B clients an unbeatable cost-to-performance ratio for 65W-100W PD car chargers without sacrificing thermal efficiency.
Automotive-grade 6.6kW On-Board Chargers require extreme ruggedness against moisture, vibration, and heat. Caiku’s liquid-cooled OBC modules feature IP67 sealing, high-efficiency PFC loops, and fully isolated CAN-bus communication for seamless vehicle ECU coordination.
For high-capacity EV charging stations reaching up to 600kW, Caiku utilizes dynamic matrix power routing. This software-driven power allocation routes power modules dynamically based on real-time Battery Management System (BMS) requests, minimizing energy degradation and maximizing throughput.
