Marine Charge Distribution Circuit for Isolated Battery Priority

The patent divides the power storage system into multiple isolated banks (primary and secondary) with separate charging paths from the alternator. Each bank is equipped with its own control circuitry and isolation mechanisms, allowing independent charge management. This segmentation prevents current from flowing between banks and eliminates abrupt load fluctuations on the engine by providing controlled, staged charging.

The patent introduces isolators as intermediary components between the alternator and power storage banks, and between the banks themselves. These isolators act as controlled gates that permit or block current flow based on system conditions. The charge sensor and control circuitry serve as intermediaries that monitor bank states and manage charging sequences, providing sophisticated control without requiring direct complex interconnections between all components.

The patent implements a prioritized charging sequence where the primary power storage bank is charged first to ensure adequate charge availability for essential propulsion functions. Only after the primary bank reaches a sufficient charge level does the system begin charging secondary banks. This preliminary action guarantees that the primary bank maintains the charge necessary for starting the engine and operating critical systems, while still enabling efficient charging of the overall system.
