Engineered for extreme reliability, rapid scalability, and seamless integration into Seattle's maritime, transit, and enterprise campus networks.
As the Pacific Northwest transitions rapidly toward zero-emission transportation frameworks mandated by Washington State's Clean Energy Transformation Act (CETA), municipal fleet managers, logistics operators, and commercial real estate developers face a structural paradigm shift. Traditional low-voltage (300V–400V) charging systems are increasingly constrained by thermal limits, excessive current draw, resistive copper losses, and massive cable weight. To meet the demanding operational throughput of Seattle's industrial corridors along Interstate 5 (I-5), the Port of Seattle, and high-density tech hubs in South Lake Union, high-voltage (800V–1000V) direct-current (DC) fast-charging architecture has become an absolute necessity.
Our OEM high-voltage charging solutions utilize advanced Silicon Carbide (SiC) power conversion modules, shifting the fundamental thermal management curve. By doubling the operational voltage, current flow for equivalent power output is reduced by 50%. According to Joule's First Law ($P_{loss} = I^2 R$), cut-in-half electrical current yields a 75% reduction in thermal dissipation losses within system interconnects, transformers, and liquid-cooled charging cables. This engineering breakthrough guarantees sustained, unthrottled peak power delivery even during Seattle's damp, low-temperature winter mornings and extended heavy-duty commercial operations.
Third-generation wide-bandgap SiC power modules deliver up to 96.8% efficiency, dramatically reducing operational electricity expenses and dynamic thermal load under continuous 240kW–480kW charging demands.
Seamless hardware-level switching between SAE J1772/CCS1, SAE J3400 (NACS), and ISO 15118 (Plug & Charge), facilitating smooth transitions for legacy and next-gen electric fleets across Washington state.
Native embedded 4G/5G telematics modules communicate via OCPP 1.6J/2.0.1 directly with Seattle City Light (SCL) and Puget Sound Energy (PSE) demand-response APIs for dynamic load management.
Custom OEM charging hardware cannot rely on a one-size-fits-all manufacturing model. The specific topography, maritime climate, grid load profiles, and aggressive decarbonization timelines of King County and the Puget Sound region demand specialized, heavy-duty engineering customization.
Scenario: Heavy-duty drayage trucks, yard tractors, and electric tugboat shore-power systems operating along Harbor Island and Terminal 5 require sustained multi-megawatt energy throughput.
OEM Solution: High-voltage dual-gun liquid-cooled DC fast chargers (up to 480kW per terminal) built with IP67 marine-grade stainless steel enclosures (316L). Features multi-stage conformal anti-corrosion coating to withstand saline fog, ambient moisture, and continuous heavy machinery vibration.
Scenario: Multi-story parking structures in South Lake Union, Bellevue, and Redmond demand dense employee charger deployments without triggering severe utility peak-demand surcharges.
OEM Solution: Compact floor-standing and wall-mounted smart DC units paired with integrated Dynamic Load Balancing (DLB). System algorithmically throttles power across 20+ output guns, matching real-time transformer headroom supplied by Seattle City Light.

OEM Solution: Ultra-fast 800V pantograph and floor-mount CCS1/NACS chargers equipped with automated isolation resistance testing ($R_{iso} > 50 M\Omega$), guaranteeing zero ground-fault trips despite soaked ground cables and rain-drenched connectors.
Scenario: Automated Guided Vehicles (AGVs), e-cargo bikes, and micro-mobility fleets operating in Kent Valley industrial parks require continuous 24/7 battery swapping and rapid top-ups.
OEM Solution: Modular 60V/72V LiFePO4 swappable battery cabinets integrated with high-efficiency industrial chargers, enabling 15-minute battery swaps for automated robotics and light commercial delivery vehicles.
