ELECTRIC BATTERIES

A transmission line 16 operative as an antenna for use with a plurality of electric battery cell modules. Each electric battery cell module comprises at least one electric battery cell 12 and a module antenna 14. The transmission line 16 comprises an elongate shape and is configured to provide near field radio wave coupling of data with each of the plurality of electric battery cell modules spaced apart along its length, wherein the near field radio wave coupling is provided by the transmission line 16 with the module antenna 14 of each one of the plurality of electric battery cell modules.
