Modular electrical power distribution system with module detection systems and methods

A method of detecting one or more characteristics of a modular electrical power distribution system comprising a plurality of controllers in communication with one another via a shared serial communication bus and a module detection signal line, the method comprising:

• sending, via the module detection signal line, a first module detection signal to a first load controller of the plurality of controllers;
• receiving, via the shared serial communication bus, a first module identification signal from the first load controller;
• receiving, via the shared serial communication bus, a second module identification signal from a second load controller of the plurality of controllers;
• and
• receiving, via the shared serial communication bus, a third module identification signal from a power input controller of the plurality of controllers.

A method of detecting one or more modules of a modular electrical power distribution system comprising a plurality of controllers in communication with one another via a shared serial communication bus and a module detection signal line, the method comprising:

• receiving, by a controller of the plurality of controllers and via the module detection signal line, an input detection signal from a preceding controller of the plurality of controllers along the shared serial communication bus;
• sending, by the controller via the shared serial communication bus, a module identification signal to a master controller;
• and
• sending, by the controller over the module detection signal line, an output detection signal to a succeeding controller of the plurality of controllers along the shared serial communication bus.
