Industry High: Jianwang Technology's Energy Storage Products Successfully Pass Full-Scenario Thermal Runaway Extreme Tests

1. Extreme Performance: No Re-ignition within 24 Hours, Temperature Drops Rapidly within 2 Hours 

Performance of Jianwang Technology's Energy Storage System in Extreme Thermal Runaway Tests* 

To verify the safety boundaries and active defense capabilities of energy storage systems in extreme thermal runaway scenarios, Jianwang Technology, in collaboration with State Grid Zhejiang Integrated Energy Service Co., Ltd., recently completed a full-scenario thermal runaway limit test on its user-side energy storage system. The test was conducted under the most stringent preset conditions and successfully achieved zero spread of thermal runaway from a single cell, a rapid temperature drop to 96°C within 2 hours, and ensured no re-ignition or temperature rise during a 24-hour static period.

II. Technological Innovation: From Passive to Active, Safety Controlled in Advance 

This test aims to simulate the worst-case scenario where a single battery cell failure triggers a chain reaction of thermal runaway in the energy storage system, which is a core challenge to verify the ultimate safety capability of the system. The uniqueness of Jianwang Technology's test lies in that it not only focuses on the limit of passive protection but also emphasizes the verification of the effectiveness of its active safety defense system under extreme conditions. The test was conducted under military-grade standards, covering the entire safety chain from cell-level early warning to system-level fire suppression. 

During the testing process, by artificially triggering the thermal runaway of the target battery cell, the active safety closed-loop system of Jianwang Technology was comprehensively examined:

¡ Precise alarm at 68℃ (dual warnings from local and cloud)

¡ Response within 100ms (EMS executes safety strategy)

¡ Fire suppression activated at 93℃

¡ Temperature dropped to 96℃ within 2 hours

¡ No open flame throughout the process, and no temperature rise after 24 hours of static placement 

The results show that Jianwang Technology's active safety system can accurately identify, quickly intervene and effectively suppress the incipient stage of thermal runaway (at the single cell level), completely blocking the spread path of thermal runaway and controlling the risk within the smallest unit. 

III. Military-grade Quality: AI Intelligence, Multi-dimensional Protection 

Achieving the ultimate performance of "zero spread of single-cell failure" and "no re-ignition within 24 hours" lies in the "full-chain military-grade moat" safety system constructed by Jianwang Technology. This system integrates multiple active and passive protection technologies: 

Positive pressure oxygen deprivation technology (core passive fire protection): By maintaining a specific positive pressure environment inside the cabin, it continuously suppresses the concentration of flammable gases, keeping it stably below the explosion limit, fundamentally eliminating the possibility of deflagration. This technology is the key support for achieving a fire resistance integrity of over 3 hours for the cabin (far exceeding the national standard of 1 hour), building an unbreakable "safety fortress" for the system.

AI early warning algorithm (active perception): By integrating a high-density temperature sensor network (such as deployment at key points) with intelligent algorithms, it achieves millisecond-level precise identification of abnormal temperatures at the cell level, winning golden time for rapid response.

Millisecond-level coordinated control (active execution): The energy management system (EMS) and the fire protection system are deeply integrated, ensuring that warning signals can trigger precise fire suppression actions within <100ms, with a response speed hundreds of times faster than traditional minute-level solutions.

Composite fireproof materials and structural design (passive heat insulation and flame retardancy): High-performance fireproof and heat-insulating materials are applied in key areas, combined with optimized system structural design, effectively delaying heat transfer, providing a time window for active fire suppression, and preventing the spread of fire.

EMS active protection system continuously safeguards system safety: By continuously monitoring temperature, smoke, flammable gases, and electrical parameters, the system automatically identifies risks based on preset thresholds. Once a hazard is confirmed, it simultaneously executes three levels of protection - immediately cutting off the charging and discharging circuits to isolate the faulty unit, triggering the release of fire suppression media and the activation of smoke exhaust devices, and pushing alarm information to the operation and maintenance platform, forming an active safety loop from risk identification to physical suppression. 

IV. Industry New High: Extreme Data Strength, Performance Far Ahead of the Competition 

The key data generated from this extreme test has set a new benchmark for energy storage safety performance:

Test Dimension Industry Conventional Standard Jianwang Technology's Actual Test Result Leading Advantage

Fire Resistance Integrity ≥ 1 hour > 3 hours 3 times beyond the national standard

Thermal Runaway Response Time Minutes Milliseconds (< 100ms) Response speed increased by 600 times

Fire Suppression Cooling Efficiency 4 hours to 100℃ 2 hours to 96℃ Efficiency increased by 2 times +

Re-ignition Suppression Capacity Difficult to guarantee with traditional solutions No re-ignition within 24 hours Breaking the "re-ignition curse"

V. Revenue Assurance: Safety is Profit, Peace of Mind with Guarantee 

The security technology of Jianwang Technology has not only been verified through extreme tests but also has been put to the test in large-scale applications. In collaboration with State Grid Zhejiang Integrated Energy Service Co., Ltd., it has deployed nearly a thousand sets of energy storage equipment throughout Zhejiang Province, maintaining a record of "zero safety incidents" and "no non-compliance shutdowns" to date. Practical cases show that the energy storage system equipped with Jianwang Technology in a certain industrial park in Zhejiang has achieved 18 months of zero-fault operation, increasing annual revenue by 42% while significantly reducing insurance rates by 35%, strongly confirming that "safety is profit". 

Picture: Deployment of Jianwang Technology's Energy Storage System in Real Industrial and Commercial Scenarios* 

Safety is the lifeline of the energy storage industry. It cannot rely solely on passive defense; an "immune system" that proactively eliminates risks must be established. This full-scenario extreme test is an ultimate stress test of our "military-grade moat" safety concept and technical system. The results prove that even at the most extreme starting point of thermal runaway, our system can achieve precise identification, millisecond interruption, rapid cooling, and ensure no re-ignition, truly providing users with an "ultra-safe" energy storage solution. 

Jianwang Technology will continue to focus on the innovation and application of ultimate safety technologies for energy storage systems, promoting the industry's qualitative upgrade from "storing electricity" to "safely storing electricity", and safeguarding the energy transition with its core technologies.
