Abstract: A battery management system is described that includes a controller configured to control electrical charging and discharging of a plurality of blocks of a battery. The battery management system also includes an inter-block communication network including a master node and a plurality of slave nodes arranged in a ring-type daisy-chain configuration with the master node. The master node is coupled to the controller and configured to initiate all command messages sent through the inter-block communication network and terminate all reply messages sent through the inter-block communication network. The plurality of slave nodes is bounded by an initial node coupled to the master node and a last node coupled to the master node.

Abstract: In accordance with an embodiment, a method for operating a signal converter includes converting an analog input signal to a digital output signal, comprising by comparing the analog input signal to an analog comparison signal, and detecting whether the analog input signal exceeds a predetermined maximum or minimum threshold by comparing the analog input signal to an analog threshold signal. The analog comparison signal and the analog threshold signal are generated by a same digital-to-analog converter.
