SeaPower Pressure Tolerant Batteries

 

The pressure-tolerant battery blocks are characterized by a novel, deep-sea repeatedly tested design. The lithium-polymer cells are protected in durable silicone encapsulation flexible but stable under pressure from the harmful influences of the seawater. This encapsulation and the surrounding housing allow optimal cooling of the cells and protect from any mechanical influences. The battery blocks need thanks to the consistent pressure-tolerant designs no pressure chambers. This saves weight and cost.

Each battery block has its own Battery Management System (BMS), with which it is possible at any time to monitor the status of the battery and the individual cells.
The battery cells were connected in series, or in a modular series, to realize different capacity and voltage level.
