High-Power Starting Solutions
Unstoppable Power: Instant Ignition in Any Condition
Overview
When it comes to starting heavy-duty engines, backup generators, or massive industrial machinery, "failure to start" is not an option. Traditional lead-acid batteries are prone to sudden death, high self-discharge, and performance loss in cold weather. STC’s Supercapacitor Starting Systems provide the massive, millisecond-level current required to overcome mechanical inertia instantly. Designed to outlast the equipment they serve, our systems offer a "fit-and-forget" solution that ensures your high-power assets are always ready for action.
Core Applications
Marine & Harbor Crane Machinery
Ideal for large ship engines and port cranes. Our systems are unaffected by salt spray and humidity, providing reliable starting power for heavy maritime engines while reducing the weight and footprint compared to massive battery banks.
Emergency Generator Sets
Data centers, hospitals, and critical infrastructure rely on diesel generators. STC supercapacitors ensure a 100% successful start rate even after months of standing idle, providing the critical peak current that aging batteries often fail to deliver.
Heavy Duty & Mining Equipment
From massive excavators to haul trucks, starting these giants in remote areas requires massive power. Our supercapacitors are vibration-resistant and maintenance-free, perfect for the punishing environments of mining and construction.
Cold Weather Engine Start
Lead-acid batteries can lose up to 50% of their power in freezing temperatures. STC supercapacitors maintain full discharge capability at -40°C, making them the primary choice for industrial operations in arctic or high-altitude conditions.
The STC AHSC Technical Edge
Features
High Power & High Energy
High C-Rate Discharge
Millisecond Response
100,000+ Cycle Life
Benefit for Smart Grids
Provides instantaneous Cold Cranking Amps (CCA) that are 2-3 times higher than lead-acid batteries of the same size.
Delivers massive energy bursts without internal heating or chemical degradation, ensuring consistent power for the most demanding engines.
Maintains charge for extremely long periods; unlike batteries, they won't go "flat" after months of storage, ensuring standby readiness.
Eliminate the 2-year replacement cycle of lead-acid batteries. STC systems are built to last 20+ years with zero maintenance.

Typical Project Scenario
STC Supercapacitors Achieve 100% Start Success in High-Salinity & Arctic Conditions
Project Overview: The Failure of Traditional Power in Harsh Maritime Climates
At the CNOOC (China National Offshore Oil Corporation) operational zone in Tianjin Port, the reliability of emergency power is non-negotiable. The marine diesel generators (Main Power: 1200kW / Standby: 1320kW) are responsible for critical oil and gas loading tasks.
However, the port’s high salt spray, extreme humidity, and winter temperatures below -10°C proved fatal for traditional lead-acid batteries. Battery electrode corrosion and electrolyte degradation led to a startup success rate of less than 80%. With a mandatory replacement cycle of just 6 months and annual maintenance costs exceeding $4,500 per unit, the operational continuity was under constant threat.
The STC Solution: The 28V/12857F High-Power Starting Module
STC deployed a custom-engineered 28V/12857F Supercapacitor Starting Module designed specifically for heavy-duty marine engines (Runheng RH1650IX).
Built to withstand the toughest offshore environments, the STC module features:
Anti-Corrosion Architecture: A fully sealed structure using advanced corrosion-resistant materials, proven by 720 hours of rigorous salt spray testing (reducing corrosion rates by 90%).
Thermal & Electrical Stability: Low internal resistance design ensures massive instantaneous current. During 8 consecutive critical starts, the total voltage drop was a mere 1V, with a temperature rise of ≤6°C, eliminating any risk of overheating.
Smart Monitoring: Integrated RS485/CAN communication with Modbus RTU support allows for remote monitoring of voltage and temperature, seamlessly connecting to the port's central control system.
Proven Results: From 80% to 100% Success
Following a 6-month rigorous trial during peak winter, the performance data confirmed a total transformation of the power system:
Start Success Rate: Increased from 80% to a perfect 100%.
Equipment Availability: Boosted from 95% to 99.9%.
Economic Impact: Annual maintenance costs were slashed by 70%.
Service Life: The system offers a cycle life of over 50,000 starts—25 times longer than the lead-acid batteries it replaced.
Client Testimonial
"The weather resistance and maintenance-free nature of the STC module are outstanding. It has successfully withstood multiple cold waves and the corrosive marine air without a single hitch," said the Head of Operations at CNOOC Tianjin.
Conclusion: Setting the Standard for Offshore Engineering
The success at Tianjin Port provides a reliable technical blueprint for high-power emergency starts in port and offshore engineering. STC’s supercapacitor technology is driving a shift toward high-reliability, intelligent, and zero-maintenance equipment upgrades in the most challenging environments on Earth.
