Abstract: A battery for marine applications includes multiple battery cells, a sense module, a communications module, a network interface, and a battery management system, all disposed within a watertight housing. The sense module includes circuitry for generating battery status information indicative of the status of the battery cells. The communications module receives the battery status information and transmits network communication data containing the battery status information. The network interface is configured to connect directly to a standard NMEA 2000 network connector and communicate the battery status information via the standard NMEA 2000 network connector to an NMEA 2000 network. The battery management system measures the voltage of each battery cell and determines a voltage difference between a lowest-voltage cell and a highest-voltage cell and balances the charging of the plurality of battery cells to maintain the voltage difference at less than a predetermined maximum value.

Abstract: A battery for marine applications. The battery includes a plurality of battery cells, wherein the battery cells are designed to accommodate draining charge down to zero volts. The battery includes a battery management system (BMS). The BMS comprises one or more connectors, wherein the connectors are normally-closed. The BMS resides within a housing of the battery between the battery cells and one of the battery terminals. The BMS measures the voltage of each battery cell and determines a voltage difference between a lowest-voltage cell and a highest-voltage cell. The BMS may also balance the charging and discharging of the battery cells to maintain the voltage difference within a predetermined maximum value. The battery also includes a sense module designed to detect voltage changes within the battery.

Abstract: A module for managing communication among instrumentation and control devices associated with a system, and a method for using the module, enable interconnection of various devices across multiple network buses, and filtering of messages travelling between devices on disparate buses. Buses may be established wirelessly in addition to via wired connections. Additional devices may connect to a pluggable terminal interface integrated with the module. The terminal interface may connect to a configurable variety of interconnecting circuits appropriate for various types of terminal devices. An associated user interface may enable a user to configure various parameters pertaining to connected devices, including alerts to be issued when certain parameters exceed thresholds, and actions to be taken upon issuance of such alerts.
