Executive Brief
Refined Motor Company (RMC) is a Hong Kong-based pioneer specializing in the conversion of classic and contemporary internal combustion vehicles to electric power. Their core innovation is a Modular Universal Electric Powertrain System, designed for high-density integration into diverse vehicle architectures. Their primary engineering challenge lies in maximizing power density and thermal efficiency within the constrained, non-optimized spatial envelopes of vintage engine bays.
Strategic Fit & Lead Score
Lead Score: 72 (Adjacent Tech - High Power Electronics & Thermal Management)
Why this Score? RMC’s "Modular Universal" approach requires extremely compact power electronics (Inverters/Converters) to fit into various car frames. As they scale to "mass conversion," thermal throttling of SiC (Silicon Carbide) or GaN (Gallium Nitride) power modules becomes the primary bottleneck. 6C’s PCD heat spreaders and SCD substrates provide the ultimate thermal solution to increase power density while reducing the physical footprint of their powertrain.
6C Solutions Proposal
| Application Area | 6C Solution | Technical Value Prop |
|---|---|---|
| Power Electronics | PCD (Polycrystalline) Heat Spreaders | Thermal conductivity > 1800 W/mK (5x better than Copper). Allows RMC to shrink inverter size by 30-50% for tight classic car engine bays. |
| Battery Safety | BDD (Boron Doped Diamond) Sensors | Electrochemical stability for real-time monitoring of coolant degradation or early-stage "gas-out" detection in modular battery packs. |
| Fast Charging | SCD (Single Crystal) Dielectrics | Ultra-high breakdown voltage and high mobility for next-gen 800V+ conversion kits, reducing switching losses and heat generation. |
| Custom Components | Direct Diamond Coating | Wear-resistant, low-friction diamond coatings for modular gearbox components to increase drivetrain longevity without adding weight. |
| R&D Autonomy | MPCVD System Build | Enables RMC to develop proprietary diamond-on-SiC power modules in-house, securing a competitive moat in the EV conversion market. |
Engagement Hooks
- Technical Question: "As you scale your Modular Universal Powertrain, how are you addressing the thermal density limits of your SiC inverters when retrofitting into air-cooled or compact engine bays with limited airflow?"
- Value Statement: "6C can help Refined Motor Co. achieve industry-leading power-to-weight ratios by replacing standard ceramic heat sinks with CVD diamond, effectively doubling your power throughput without increasing the system footprint."
Material Specification for RMC Engineering
- PCD Wafers: Up to 5" diameter for high-volume laser-cutting into power module submounts.
- Surface Finish: Ra < 1nm (SCD) to ensure perfect thermal contact with power dies.
- Purity: 9N Hydrogen generated on-site via 6C systems to ensure zero contamination in diamond growth, maximizing thermal performance.
