Claim:
A battery charger system for an injector system, said injector system having an idle mode of operation and a non-idle mode of operation, the battery charger system comprising: (a) a first power cord for conveying AC power from a source thereof; (b) an AC/DC converter for converting the AC power received from said first power cord to DC power; (c) a second power cord for conveying the DC power received from an output of said AC/DC converter; and (d) a battery pack including a battery and a charging module, said charging module for receiving the DC power from said AC/DC converter via said second power cord and for monitoring the operating mode of said injector system such that when said injector system is operating in (I) said idle mode, said charger module provides the DC power received from said AC/DC converter to said battery for the charging thereof and (II) said non-idle mode, said charger module prevents the DC power from said AC/DC converter from reaching said battery and thus enables said battery to provide DC power to said injector system.
