Immersion-Cooled Containerized Energy Storage System

EFS 4.2 MWh DC battery container is a key platform for energy storage, designed to support reliable power storage and release. The energy storage system uses immersion liquid cooling as its core thermal management method,, providing higher heat dissipation efficiency and more precise temperature control than conventional air cooling.

During battery charging and discharging, the cooling medium quickly transfers heat away from the battery system, helping keep the battery pack within a suitable operating temperature range, from 30°C to 55°C. This helps reduce performance degradation caused by localized overheating, extends battery service life, and supports stable operation under high-rate charge and discharge conditions.

Modular Design for Transport and Deployment

The energy storage system adopts a modular standard container design and is built to fit 20-ft high-cube containers, supporting easier transport and overseas project deployment.

Cost-Efficient, Highly Integrated

The highly integrated1P104S large-pack design helps reduce cost by 5%, reduces integrated system circuits and piping by 40%, and lowers the failure rate by 3%. This improves manufacturing, installation, and maintenance efficiency while reducing lifecycle electricity costs.

Efficient Management

Rack-by-rack management helps address energy flow between racks. Cluster-level management improves system efficiency and energy efficiency while eliminating circulating current between clusters.

Immersion Safety Technology

The cells, modules, and PACK are fully immersed in the cooling medium. This design supports rapid cooling, gas isolation, and reignition suppression.

Extended Service Life

A multi-stage, variable-diameter balanced liquid cooling pipeline design keeps a stable temperature difference within 3°C, extending battery life by 20%.
