Abstract: Battery modules with anti-arcing, hot swapping, and/or self-disabling features are provided, as are systems and methods related thereto. For example, an electrical power system configured to provide backup electrical power to a load may include a battery rack having a bus configured to provide power. The system may include a battery module configured to couple with the bus and receive power therefrom, the battery module may include battery cells coupled to a pre-charge electrical path and a main electrical path, and a module controller configured to: detect that the battery module has been inserted into the battery rack, and pre-charge the battery cells of the battery module via the pre-charge electrical path until a voltage level of the battery cells may be synchronized with a voltage level of the bus.

Abstract: An electronic system includes a master module having a first control unit having one or more first serial interfaces and being programmed to output a first data signal and a first clock signal through the one or more first serial interfaces, and a slave module having a second control unit, the second control unit having a second serial interface. The slave module receives the first clock signal through the second serial interface, and the second control unit is programmed to monitor the slave module for a fault condition and output a second clock signal through the second serial interface which is (i) the same as the first clock signal if a fault condition on the slave module is not detected, and (ii) a modified clock signal having a predetermined format through the second serial interface if a fault condition on the slave module is detected.
