Expansion Box Supporting Two Different Types of Charges

      This article describes an Expansion Box of a Portable Personal
Computer which has two different charges.  One is a function of
charging a rechargable battery pack set to the system unit of the
Portable Personal Computer.  The other is a function of charging
another rechargeable battery pack set to the expansion box.

      The Figures depict a expansion box to implement the above
functions.  Fig. 1 shows a front view of this expansion box.  The
system unit, to which a rechargeable battery pack is attached, is
embedded in the expansion box.  The battery pack can be charged by a
charge control logic in the system unit using a DC power source from
the expansion Box.  Fig. 2 shows a rear side of this expansion box.
Another rechargeable battery pack is directly embedded in the
expansion box.  The battery pack can be charged by a charge control
logic in the expansion box using another DC power source in the
expansion box.  The expansion box makes it possible to charge two
battery packs at the same time.

      The numbers of the system units and the battery packs which the
expansion box can accommodate are not limited.
