Lithium Ion Batteries
Rechargeable, Pressure Tolerant

Phoenix International Holdings, Inc (Phoenix) has developed the next generation underwater battery.  Proven on multiple ROV excursions into RMS TITANIC (>12,000 fsw), these rechargeable batteries are high energy, pressure tolerant, fault tolerant and designed for S9310 requirements.  Phoenix Cells include a proprietary, networked Battery Management System (BMS) providing charge and discharge protection and more.  The Modules, of 8, 12, or 13 cells in series, have a BMS header board and can be connected in series and parallel to meet the system’s voltage, load, and energy needs.

Battery Features

Pressure Tolerant - Designed to operate at ambient pressure or 1 atmosphere.  All components tested to 10,000 psi in production.  Proven in over 1000 hours under pressure.

Battery Management System (BMS) – Three-tier design: Cell, Module, Battery.  Electronics embedded in each Phoenix Cell protect the cell during charge, discharge and handling.  The networked modules and cells provide complete, real time reporting and control of the battery and each cell. 

High Energy - State of the art chemistry is packaged to maximize energy density with high efficiency BMS.

Easy Operation - BMS isolates cells for storage/shipping.  Modules stack to supply up to 275 VDC (higher voltage in development).  Charge with any DC supply at nominal 48VDC or 300VDC, no equalization is required.  Plug and Play cell and module replacement.

Robust – Modules can be stacked in parallel and series.  BMS resets after faults.  BMS recovers remainder of a voltage stack’s energy after a single cell failure.

Safety Approval – Navy S9310 safety review approved a system with Phoenix batteries for submarine T&E. Transportation testing is planned. 

Standard Modules

Phoenix produces a range of modules for assembly in series and parallel to make batteries of any voltage, power, or energy.  Upon request, module configurations can be optimized for specific requirements.  A high energy, large 12 cell module has been developed for 21 inch and larger diameter UUVs.
