On June 13, 2024, Lishen released the new generation 20ft 5MWh liquid-cooled container and low-voltage residential energy storage product LS-C15K-W.
5MWh AC and DC integrated energy storage system
This new system integrated proprietary 314Ah cells and standardized 2P52S battery modules, along with a string PCS that manages each cluster for enhanced safety, integration, modular design, and long cycle life.
Five-layer safety protection: Lishen emphasizes safety with a multi-faceted approach, covering cell technology, electrical safety, thermal management, fire protection, and system-level security.
Highly integrated design: The 20ft container, leveraging Lishen's 314Ah cells, features a compact design that increases energy density by 17%. It combines a multi-liquid parallel flow path design with an integrated liquid-cooling solution, ensuring a temperature difference within the cycle of less than 3°C. The system design incorporates a highly integrated concept that accounts for thermal management, BMS control, safety protection, and other functions.
AC and DC integrated innovation: The system moves beyond traditional setups by implementing a "one cluster, one inverter" approach, the discharge capacity throughout the system's entire lifecycle can be increased by about 8%.
Long cycle life: The system's temperature control ensures a long cycle life by maintaining container temperature differences at less than 3°C, cluster-level differences under 2.5°C, and module cell differences under 2°C.
New generation of wall-mounted residential energy storage product
Intelligent design: LS-C15K-W features an intelligent, integrated design, enabling remote monitoring and customizable operation modes via a mobile app and ensures high safety and longevity with a plug-and-play setup.
Thin and lightweight design: LS-C15K-W embodies Lishen's commitment to efficiency and minimalism, equipped with 280Ah high-performance cells and a sleek profile at only 94mm thick, and the wall-mount design conserves space.
Safety design: LS-C15K-W incorporates forced air cooling to maintain an internal temperature difference of 2.5°C or less, along with an aerosol-based automatic fire-suppression system to mitigate fire risks and enhance home safety.
