1. A serial connection apparatus comprising:
a connector group including first to mth connector modules (m is a natural number of 2 or more) provided on a one-to-one basis to first to mth cell slots provided in a cell holder, wherein each of the first to mth connector modules includes a first connector and a second connector; and
a wire bundle electrically connected to the first to mth connector modules,
wherein the first connector of the first connector module is configured to be electrically connected to a first power terminal of a charge/discharge unit,
wherein the second connector of the mth connector module is configured to be electrically connected to a second power terminal of the charge/discharge unit,
wherein the second connector of a jth connector module (j is a natural number less than m) is configured to be electrically connected to the first connector of a (j+1)th connector module via the wire bundle,
wherein, when an ith cell slot (i is a natural number of m or less) is in an empty state without a battery cell disposed therein, the first connector of an ith connector module is configured to be electrically connected to the second connector of the ith connector module via the wire bundle, and
wherein, when the ith cell slot is in an occupied state with a battery cell disposed therein, the first connector of the ith connector module is configured to be electrically connected to the first electrode terminal of the battery cell disposed in the ith cell slot, and the second connector of the ith connector module is configured to be electrically connected to the second electrode terminal of the battery cell disposed in the ith cell slot.
