E TANK Commercial Liquid-Cooled Energy Storage Integrated Solution

Breaking away from traditional bottom liquid cooling, the E TANK utilizes Gold's innovative Large Surface Side Liquid Cooling Technology:

• ► 70% Increased Coverage: Heat dissipation on both sides bonds the core heat source, drastically shortening the heat conduction path.
• ► <2.6°C Temperature Difference: Achieves a 50% temperature equalization improvement through a dual-side spiral cooling path and dynamic regulating flow.
• ► Expansion Constraint: Rigid constraint to cell expansion utilizing a large surface side plate dual plate clamping structure, which actively blocks the spread of heat.
•  

The E TANK introduces an industry-leading intelligent safety system combining physical isolation with active suppression:

• ► Cell Level: The G2.BMS detects abnormal cells; the ICM opens valves for point-to-point coolant spraying directly onto the affected cell.
• ► Pack Level: Photodetectors identify cell fires, prompting the ICM to release fire suppression chemicals specifically within the battery compartment.
• ► Cabinet Level: Equipped with a DN65 interface for manual hydrant operation and 110-degree atomizing spray heads providing water mist grade coverage.
• ► Class IP67 & Isolation: Independent subdivision of the battery compartment, dry gas inflation, and built-in desiccants prevent condensation.

Removing redundancy through a thin topology, Gold Electronic has integrated five distinct systems (BMS, EMS, PCS, TMS, FFS) into one powerful Integrated Control Module.

• ► Direct Execution: This innovative secondary architecture speeds up system response by 20% by optimizing communication and control links.
• ► Space Optimization: Combining the HVB, ICM, PCS, and AUX reduces the electrical cabin size by 50% or more, resulting in a 10% space utilization improvement and a 15% reduction in hardware costs.

Management is burden-free thanks to cutting-edge local and cloud interfaces:

• ► ESPID Visual Light Board: A screen-less translator providing blue/green/yellow/red status indicators and direct fault code displays.
• ► ICM Lightweight Diagnostic Model: Utilizes AI diagnosis, historical cases, and an expert library to provide root cause pinpointing.
• ► Comprehensive App: Easy operation, remote status checks (e.g., SOC, Energy efficiency), and push notifications for anomalies.
• ► Data Service Center: Supports virtual electricity market trades, asset appraisal, and AI energy forecast settlements.

Unlike traditional bottom liquid cooling, Gold's innovative technology utilizes a double side symmetrical layout with a spiral cooling path. This increases the coverage area by 70%, bonds the core heat source directly to shorten the heat conduction path, and improves temperature equalization by 50%.

The E TANK is designed for maximum space utilization. The overall cabinet size is just 980 * 1330 * 2251 mm. This means it requires a floor surface of less than 1.3m² and a space volume of less than 3m³, representing a 30% volume reduction compared to conventional designs.

The system operates on three tiers: 1) Cell Level: The G2.BMS locks abnormal cells and sprays coolant directly on them. 2) Pack Level: Photodetectors identify fire, triggering the release of fire suppression chemicals in the battery compartment. 3) Cabinet Level: Features a DN65 interface for manual hydrant operation and utilizes 110-degree atomizing spray heads for water mist grade coverage.

The ICM is a highly integrated architecture that combines 5 systems into one chip: BMS (Battery Management System), EMS (Energy Management System), PCS (Power Conversion System), TMS (Thermal Management System), and FFS (Fire Fighting System). This direct execution speeds up response by 20% and optimizes communication efficiency.
