11. An apparatus, comprising:
-
a plurality of battery modules serially intercoupled together, each module including a housing with an anode connector and a cathode connector, wherein an anode connector of a first module is coupled to a cathode connector of a second module, and wherein each said module includes a reference developed from a static measurement of a reference positional attribute of said plurality of modules wherein said reference positional attribute of each particular module identifies a particular location of said particular module in said serially intercoupled plurality of battery modules relative to other battery modules of said plurality of modules; a processing system, coupled to each said module, for determining a plurality of current positional attributes for said plurality of battery modules, one current positional attribute associated with each said module of said plurality of modules wherein said current positional attribute of each particular module identifies a particular location of said particular module in said serially intercoupled plurality of battery modules relative to other battery modules of said plurality of modules; a comparator, coupled to said processing system, for comparing a reference positional attribute for a particular reference associated with a particular one battery module to said current positional attribute of said particular one battery module; and a monitor, coupled to said comparator, for flagging said particular one battery module when a predetermined relationship exists between said reference positional attribute and said current positional attribute. - View Dependent Claims (12, 13, 14, 15)

16. A method, the method comprising the steps of:
-
(a) determining dynamically a plurality of current positional attributes across a plurality of serially intercoupled battery modules wherein said current positional attribute of a particular battery module identifies a particular location of said particular battery module in said serially intercoupled plurality of battery modules relative to other battery modules of said plurality of modules; and (b) comparing, for a particular one of modules, said current positional attribute with a predetermined reference developed from a dynamic determination of a reference positional attribute of said plurality of modules wherein said reference positional attribute of a particular battery module identifies a particular location of said particular battery module in said serially intercoupled plurality of battery modules relative to other battery modules of said plurality of modules; and (c) flagging said particular one battery module when a predetermined relationship exists between said reference positional attribute and said current positional attribute. - View Dependent Claims (17, 18, 19, 20)

21. A method, the method comprising the steps of:
-
(a) determining dynamically a plurality of current positional attributes across a plurality of serially intercoupled battery modules after installation into a vehicle wherein said current positional attribute of a particular battery module identifies a particular location of said particular battery module in said serially intercoupled plurality of battery modules in said vehicle relative to other battery modules of said plurality of modules; and (b) comparing, for a particular one of modules, said current positional attribute with a predetermined reference developed from a dynamic determination of a reference positional attribute of said plurality of modules wherein said reference positional attribute of a particular battery module identifies a particular location of said particular battery module in said serially intercoupled plurality of battery modules relative to other battery modules of said plurality of modules wherein said reference positional attribute was developed before said plurality of serially intercoupled battery modules were installed into said vehicle; and (c) flagging said particular one battery module when a predetermined relationship exists between said reference positional attribute and said current positional attribute.
