Abstract
A distributed battery control network (14) for a battery string (12) has a plurality of sensing modules (SM) each associated with one of the batteries in the battery string (12). Each of the sensing modules has a respective sequencing input (SI) and a sequencing output (50). Said plurality modules have a sequencing input with a predetermined signature type, storing said address in a particular one of said plurality modules with said sequencing input equal to said signature type, and generating an identifying signature at an output of said particular one of plurality modules with said sequencing input equal to said signature type. A network (22) is coupled to each of the sending modules. A controller (24) is coupled to the bus and communicates with each of the sensing modules. The controller (24) loads each of the sensing modules with an address and a signature type.
