Obsidian Deep-Burial Energy Storage System (Star Obsidian Series)

Core Advantages of Obsidian Deep-Burial Energy Storage System (Star Obsidian Series)

Based on its technical features and industry breakthroughs, the advantages of this system are mainly reflected in the following dimensions:

🔒 Intrinsic Safety: Eliminating Fire and Explosion Risks at the Source

Oxygen-Isolated Explosion-Proof Design: Adopting an underground burial architecture combined with vacuum armored cabins, it completely cuts off oxygen supply, achieving “absolute zero fire and explosion”. Even if thermal runaway of the battery cell occurs, it will not spread to the surface.

Superior Explosion-Resistant Structure: The honeycomb explosion-proof cabin raises the thermal runaway temperature threshold to over 1800℃, far exceeding industry standards, effectively suppressing battery cell explosions and secondary deflagrations.

Extreme Environmental Protection: The multi-layer pressure-resistant structure can withstand magnitude 8 earthquakes and 200-meter deep water immersion. The enclosed underground environment shields the system from external fire sources and extreme weather conditions.

📏 Spatial Revolution: 100% Release of Ground Resources

Underground Deployment Mode: Energy storage modules are deeply buried underground, allowing the ground to be fully restored for planting, hardening, or other purposes. It solves the pain points of traditional energy storage systems, such as large land occupation and low land utilization efficiency, making it particularly suitable for land-scarce scenarios like urban areas and industrial parks.

Modular Integration: The three-level integrated architecture of “cell-module-cabin” enables flexible installation and rapid capacity expansion according to demand.

⚡ Efficiency Upgrade: Lower Losses, Higher Returns

No Additional Heat Dissipation Energy Consumption: The constant-temperature underground environment eliminates the need for heat dissipation equipment such as air conditioners and fans. The system conversion efficiency is over 10% higher than that of traditional energy storage systems, reaching up to 99%.

Extended Service Life via Small Temperature Difference: The stable underground temperature minimizes the temperature difference of battery cells, reduces cycle loss, and significantly prolongs battery service life.

🌍 Eco-Friendly: Low-Carbon Adaptation Throughout the Life Cycle

Zero Pollution Leakage: The outer shell adopts a double-layer aluminum oxide + PE anti-seepage layer with a permeability rate lower than 1×10⁻¹² cm/s, completely preventing electrolyte from contaminating soil and groundwater.

Low Noise and No Visual Interference: Underground deployment drastically reduces equipment noise, and there is no visual obstruction from surface equipment, making it suitable for ecologically sensitive areas and residential areas.

🧠 Intelligent Operation and Maintenance: Full-Process Controllability and Early Warning

AI Real-Time Monitoring: Equipped with an intelligent management system, it monitors key parameters such as voltage and temperature in real time, enabling early fault diagnosis and precise location, and improving the efficiency of operation and maintenance response.

Three-Level Protection Mechanism: Three-level overcurrent protection at the pack level, cluster level, and PCS level, with graded and precise shutdown, ensuring that faulty branches do not affect the stable operation of other units.
