First Claim
1. A modular energy storage network system for an aircraft having a plurality of one of subsystems and functions, the system comprising:
- a plurality of distributed modular battery networks, each modular battery network being at a location distinct from other battery networks, each modular battery network including at least one self-contained energy storage device, each modular battery network being fully independent from each of the plurality of one of subsystems and functions;
a power distribution module coupled to each of the plurality of distributed modular battery networks, the power distribution module being configured to;
determine a total available capacity for each modular battery network by adding an available capacity for each battery in a respective modular battery network;
determine a power priority for each of the plurality of one of subsystems and functions; and
selectively distribute power from the plurality of distributed modular battery networks to at least one of the plurality of one of subsystems and functions based on the power priority for each of the plurality of one of subsystems and functions and the total available capacity for each modular battery network.

Abstract
A system and methods for life optimal power management of a distributed or centralized battery network system for use in aircraft functions and subsystems are disclosed. The method determines power priority of the subsystems, and selectively distributes power from the battery network system to the subsystems based on the power priority. Concurrently with distributing power, the method manages the energy in the battery network system. To determine whether the battery power is sufficient for aircraft functions, the method also computes and indicates the actual available energy left in the battery network systems. With this approach, the system and methods can provide a persistent power supply in the event an unexpected battery failure occurs, thereby enabling the aircraft to safely maintain flight operability despite a battery failure.
