Abstract
A battery pack includes a plurality of secondary batteries and a plurality of bus bars. The secondary batteries are connected to each other in series and in parallel. Each of the secondary batteries includes first and second electrode terminals. Each of the bus bars electrically connects one of the secondary batteries to a neighboring one of the secondary batteries. The bus bars include a first bus bar having a first sectional area and a second bus bar having a second sectional area different from the first sectional area.

A battery pack, comprising:
- a plurality of secondary batteries connected to each other in series and in parallel, each of the secondary batteries including a first electrode terminal and a second electrode terminal;
- and
- a plurality of bus bars, each of the bus bars electrically connecting one of the secondary batteries to a neighboring one of the secondary batteries, wherein the bus bars include a first bus bar having a first sectional area and a second bus bar having a second sectional area larger than the first sectional area,
- wherein:
- the secondary batteries are included in at least two parallel groups in which the secondary batteries are connected to each other in parallel,
- the at least two parallel groups are connected to each other in series,
- the first bus bar connects, in parallel, the secondary batteries to each other within each of the parallel groups, and
- the second bus bar electrically connects the at least two parallel groups to each other in series.

An apparatus, comprising:
- a first bus bar;
- and
- a second bus bar,
- wherein the first bus bar is electrically connected to an electrode terminal of a first battery and an electrode terminal of a second battery, and the second bus bar is electrically connected to the electrode terminal of the second battery and an electrode terminal of a third battery,
- wherein the first bus bar has a first section having a uniform first thickness overlapping an interface between the the first and second batteries such that the thickness of the first section at one side of the interface is the same as the thickness of the first section at the other side of the interface,
- wherein the second bus bar has a second section having a uniform second thickness overlapping an interface between the second and third batteries such that the thickness of the second section at one side of the interface is the same as the thickness of the second section at the other side of the interface, and
- wherein the second thickness is different from the first thickness.
