SeaPower Pressure Tolerant Batteries

 

The pressure-tolerant battery is characterized by a novel design, which was repeatedly tested in deep-sea surroundings. The electronics are protected from the harmful influence of seawater in a durable silicone encapsulation. Which is flexible but stable under pressure at the same time. This encapsulation and the rugged housing allows optimal cooling of the cells and additional protection from any mechanical influence. Thanks to the consistent pressure-tolerant design, the Battery needs no pressure chamber at all. 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.
