Electric load management center including gateway module and multiple load management modules for distributing power to multiple loads
First Claim
1. An electrical power distribution center comprising:
- a gateway module including logic to interface to a vehicle management computer (VMC) via a dual redundant standard data bus, wherein the gateway module comprises redundant microcontrollers operably connected to the VMC for selectively controlling supply of electrical power to a plurality of separate electrical loads;
two internal serial data buses, wherein the two internal serial data buses are of two different types and the redundant microcontrollers are each operably connected to the two internal serial data buses; and
a plurality of Load Management Modules (LMMs), each Load Management Module operably connected to the internal serial data buses for receiving control commands from the gateway module, wherein each Load Management Module comprises;
a local microcontroller;
a plurality of power switching devices; and
a plurality of switch controllers corresponding to the plurality of power switching devices for interfacing the power switching devices to the local microcontroller, wherein each of said switch controllers performs RMS value processing and I2t value calculation.

Abstract
An electrical distribution system is disclosed that includes a gateway module (100) including logic (112) to interface to a vehicle management computer (VMC) (50) via a dual redundant standard data bus (1). The gateway module (100) has redundant microcontrollers (114, 116) operably connected to the VMC (50) for selectively controlling supply of electrical power to a plurality of separate electrical loads (120). The electrical power distribution center also has two internal serial data buses (2,3) that are of two different types. The redundant microcontrollers (114, 116) are each connected to the two internal buses (2,3). A plurality of Load Management Modules (300) is provided. Each are connected to the internal serial data buses (2,3) for receiving control commands via the gateway module (110). Each Load Management Module (300) includes a local microcontroller (310); a plurality of power switching devices (320); and a plurality of application specific integrated circuits (330) corresponding to the plurality of power switching devices (320) for interfacing the power switching devices (320) to the local microcontroller (310).
