Performance & Features

Lifespan Extension Strategy

The immersion environment provides a more ideal storage and operation condition for battery cells. It effectively inhibits adverse chemical reactions inside the battery, slows down the aging process, and significantly extends the overall service life of the battery.

Convenient Maintenance Design

Through an ingenious structural layout, only the battery cell portion is immersed in the insulating coolant, while other key components are placed externally. This greatly simplifies maintenance work, solves the problem of high maintenance difficulty in existing immersion-type battery packs, and paves the way for the widespread application of this technology in large-scale energy storage power stations.

Excellent Safety

By immersing battery cells in a special insulating coolant, contact between cells experiencing thermal runaway and oxygen is effectively isolated. At the same time, the temperature of flammable gases is reduced. Rigorous testing has verified that this method can completely eliminate the safety hazards of fire and explosion.

Efficient & Flexible

The innovative flow channel design works in synergy with the immersion coolant to achieve all-round (6-sided) simultaneous heat dissipation for battery cells. Compared with the single bottom-side heat dissipation of the second-generation baseplate liquid cooling, this solution significantly improves heat dissipation efficiency. Additionally, the temperature distribution across the battery cells is more uniform, with the temperature difference of the entire cell cluster controlled within 1.5°C, which is far lower than the 3°C+ level of the second-generation technology.

Optimizing the Short-Board Effect

Leveraging the excellent heat dissipation capability of immersion technology and combined with our company's patented manual balancing technology, this solution effectively enhances the consistency among battery cells, delays the occurrence of the short-board effect, and ensures the maximum capacity utilization of the system during long-term operation.

Economic Efficiency

Relying on an advanced system integration strategy, this technology has achieved the commercial implementation of immersion-type energy storage technology with a relatively low cost threshold. Compared with the second-generation system, although there is a slight increase in cost, the performance improvement it brings far exceeds the investment, demonstrating extremely high economic value.
