SHENZHEN, China, 6 de marzo de 2025 /PRNewswire/ -- El sistema de almacenamiento de energía (ESS) Smart String & Grid Forming de Huawei Digital Power ha superado con éxito la prueba de ignición extrema, presenciada por clientes y DNV, una organización independiente reconocida mundialmente en aseguramiento y gestión de riesgos. Esta innovadora prueba, llevada a cabo bajo escenarios reales y metodologías innovadoras, valida las capacidades del ESS en condiciones extremas, marcando un hito significativo en el avance de las normas de seguridad para la industria de almacenamiento de energía.

Verificación en condiciones extremas: Ensayo de ignición en todos los escenarios

En línea con el método de prueba estándar internacional UL 9540A, Huawei Digital Power elevó el rigor de la prueba aumentando significativamente el número de células sometidas a fuga térmica. Este enfoque verificó exhaustivamente las capacidades de protección de seguridad del Smart String & Grid Forming ESS en escenarios de ignición extremos, estableciendo un nuevo punto de referencia para las pruebas de seguridad.

Destacado 1: Verificación en el mundo real con productos 100% fabricados en serie

La prueba se realizó en condiciones que reflejaban estrictamente las aplicaciones del mundo real. Cuatro Smart String & Grid Forming ESS (contenedores A, B, C y D) eran productos reales fabricados en serie. Cargados al 100% de su estado de carga (SOC), se desplegaron de acuerdo con las autorizaciones mínimas de mantenimiento y seguridad requeridas para una planta. Todo el proceso de prueba fue espontáneo, sin intervención manual, lo que garantizó un entorno de verificación extrema realista y completo a nivel de sistema.

Destacado 2: El disparo de 12 células en la pista térmica no provoca incendios ni explosiones tras múltiples intentos de ignición

En los ESS convencionales, la fuga térmica en una sola célula suele provocar la liberación de gases combustibles en el contenedor, lo que da lugar a incendios o explosiones. Sin embargo, en el Smart String & Grid Forming ESS de Huawei (contenedor A), el escape térmico se produjo en 12 celdas sin incidentes. El innovador mecanismo de defensa combinado del sistema (barrera de oxígeno de presión positiva y conducto de escape de humo direccional) ventiló eficazmente los gases combustibles. La ignición manual no desencadenó incendios ni explosiones, y el problema de seguridad se resolvió automáticamente. Esto demuestra la capacidad del ESS para prevenir incendios y la propagación de fallos en el nivel de la batería.

Destacado 3: La capacidad de resistencia al fuego de última generación evita la propagación en un escenario de combustión con suministro máximo de oxígeno

Para simular situaciones de combustión a gran escala, la prueba aumentó progresivamente el número de celdas con fuga térmica hasta que todo el paquete de baterías se vio afectado, al tiempo que se proporcionaba el máximo suministro de oxígeno para crear condiciones de combustión más estrictas. A pesar de estas dificultades, la temperatura máxima de las celdas en los contenedores adyacentes B, C y D alcanzó sólo 47 °C, muy por debajo del umbral de fuga térmica. El desmontaje posterior a la prueba confirmó la integridad del cuerpo del ESS, la capa ignífuga y los paquetes de baterías internos, lo que demuestra la resistencia del sistema en situaciones extremas.

Destacado 4: La lenta progresión de la avería proporciona un tiempo crítico para intervenir a tiempo y evitar accidentes graves

Un ESS convencional corre el riesgo de incendiarse o explotar inmediatamente si se produce una fuga térmica en una sola célula, lo que a menudo provoca accidentes graves. Por el contrario, el ESS de Huawei (contenedor A) retrasó el inicio del incendio durante 7 horas en situaciones extremas, incluso a medida que aumentaba el número de celdas con fuga térmica. Esta lenta progresión del fallo permite al personal de emergencia disponer de tiempo suficiente para una intervención temprana, mitigando los riesgos y garantizando la seguridad del personal y de los bienes.

Avance técnico: Redefinición de la lógica de seguridad de ESS

La seguridad de los ESS es fundamental para el desarrollo sostenible y de alta calidad de la industria de las energías renovables. El éxito de esta prueba subraya el importante avance de Huawei Digital Power en la seguridad del sistema, ofreciendo una protección integral desde el nivel de la célula de la batería hasta todo el sistema. A través de la innovación arquitectónica, la compañía ha mejorado el mecanismo de protección de seguridad del ESS desde el nivel de contenedor (estándar de la industria) hasta el nivel de paquete, evitando eficazmente la propagación de la fuga térmica.
