JDEnergy eBlock-100C Passes UL 9540A Test, Forging a Strong Safety Barrier for Energy Storage

2025-12-30
Recently, in the globally recognized and highly challenging UL 9540A test, Singularity Energy’s eBlock‑100C delivered an impressive performance: it successfully contained thermal runaway within a single unit, with no propagation to adjacent cabinets.This means the product has passed the UL 9540A test and obtained a “safety passport” for entering the global market, laying a solid foundation for the global expansion of its energy storage business.

48 Hours of Rigorous Testing:

Building a Strong Safety Barrier for Energy Storage Systems

 
 
The test was conducted in strict accordance with the UL 9540A standard, focusing on the module and unit levels to highly simulate extreme scenarios of thermal runaway in energy storage systems.After 48 hours of severe testing, the eBlock‑100C achieved outstanding core data, fully exceeding international safety standards:
 
  • Test cabinet: When a single PACK was triggered into thermal runaway, the peak temperature of the out-of-control cell exceeded 800°C.Nevertheless, the cabinet remained stable — no fire, no explosion, no disintegration; the main internal structure stayed intact, with no obvious damage to the exterior.
 
  • Adjacent cabinets: The maximum temperature near the cell position was only 31°C, far below the international standard threshold of 179°C.
 
Witnessed throughout by the international authoritative certification body CSA Group, the eBlock‑100C successfully passed the UL 9540A test.It strictly confined thermal runaway to a single cabinet, effectively blocking its spread to adjacent units, and established a strong safety defense line from unit to system level.

PV‑Storage Integration, Safety as the Foundation

UL Certification Boosts Global Expansion

 
With PV‑storage integration as its core advantage, the eBlock‑100C integrates photovoltaic MPPT, battery DCDC, and bidirectional DC/AC conversion.It supports grid‑tied and off‑grid operation, as well as various EMS modes including self‑consumption, economic mode, and backup power mode.
 
 
Thanks to its diversified modes, flexible deployment and easy installation, the eBlock‑100C can adapt to a wide range of application scenarios, such as shopping malls, office buildings, hotels, commercial complexes, factories, distributed PV, distribution station energy storage, zero‑carbon parks, microgrids, heat pumps and diesel generators.It precisely matches the strong overseas market demand for integrated PV‑storage solutions.
 
Meanwhile, the eBlock‑100C features a robust safety system based on three levels of active protection: cell level, PACK level and cabinet level.Passing the UL 9540A test not only reaffirms its system‑level safety capability under extreme working conditions but also further enhances its competitiveness in overseas markets.
 
With the accelerated advancement of its globalization strategy, Singularity Energy’s certification system is becoming increasingly complete.At present, the company’s products have successfully obtained multiple domestic and international authoritative certifications, including IEC61000, IEC62477, IEC62619, VDE4110, IEC60730 and GB/T 34120, providing solid support for the smooth delivery of global projects.
 
The UL 9540A test is a “touchstone” for evaluating the safety of energy storage systems and a “catalyst” for promoting industrial safety upgrades.In the future, Singularity Energy will always adhere to customer value orientation, continuously deepen product safety design, safeguard the stable operation of energy storage projects, and contribute wisdom and strength to the sustainable development of the global energy storage industry.
