Abstract

A submersible power supply apparatus provides the ability to provide power for recharging batteries used to operate underwater vehicles, manned and unmanned. A battery charging station apparatus containing at least one modular reserve battery magazine with a plurality of compartments is provided. A plurality of reserve battery modules may be respectively provided in the plurality of compartments, each of the plurality of reserve battery modules being configured to provide power when a reserve battery provided therein is activated.

Claims

1. A submersible power supply apparatus comprising:

a reserve battery module;

a modular reserve battery magazine having a compartment that houses the reserve battery module; and

a reserve battery disposed in the reserve battery module, wherein

the reserve battery module is configured to provide power under the condition that the reserve battery provided therein is activated.

2. The submersible power supply apparatus according to claim 1, wherein the modular reserve battery magazine includes a plurality of compartments that house a plurality of reserve battery modules, and

a plurality of reserve batteries each disposed in a corresponding one of the plurality of reserve battery modules.

3. The submersible power supply apparatus according to claim 1, further comprising:

an electrically powered control system for controlling the power supply apparatus.

4. The submersible power supply apparatus according to claim 3, further comprising:

a communication unit that communicates when at least one reserve battery module of the plurality of reserve battery modules is activated.

5. The submersible power supply apparatus according to claim 4, wherein

the communication unit is configured to communicate with an external control unit to remotely control the electrically powered control system.

6. The submersible power supply apparatus according to claim 4, wherein

the communication unit is configured to communicate an electrical performance of an activated reserve battery module of the plurality of reserve battery modules.

7. The submersible power supply apparatus according to claim 4, wherein

the electrically powered control system activates a predetermined number of reserve battery modules depending on an amount of power required.

8. The submersible power supply apparatus according to claim 1, wherein the power supply apparatus is provided as part of a subsea system, wherein the subsea system includes at least one of manned vehicles, unmanned underwater vehicles, distributed energy storage, and point-of-load energy storage.
