An injector system comprising: (a) an injection control unit for use in injecting a medicinal substance into a patient; (b) a controller for controlling operation of said injector system inclusive of whether said injector system operates in an idle mode or a non-idle mode; and (c) a battery charger system for providing power to said injection control unit, said battery charger system comprising: (I) a power supply for converting AC power from a source thereof to DC power; (II) a battery pack including a battery; and (III) a charging module for monitoring the mode of operation of said injector system such that when said battery pack is: (A) disconnected from said injection control unit, said battery is capable of being charged by said power supply with the DC power received therefrom when said power supply is connected to said battery pack; and (B) connected to said injection control unit, (i) upon detecting said injector system in said idle mode, said charger module routes the DC power from said power supply to both said battery for the charging thereof and said injection control unit for operation thereof; and (ii) upon detecting said injector system in said non-idle mode, said charger module prevents said power supply from charging said battery and enables said battery to provide DC power to said injection control unit.
