Thin battery pack architecture

A battery system comprising:

• a battery including:
• a first surface;
• a second surface opposite the first surface;
• a third surface extending between the first surface and the second surface and at least partially defining a thickness of the battery between the first surface and the second surface;
• a first terrace defined by the first surface and the third surface, wherein the first terrace is configured to provide access to a first electrode tab;
• and
• a second terrace defined by the first surface and the third surface, wherein the second terrace is configured to provide access to a second electrode tab;
• and
• a module seated on the first surface of the battery between the first terrace and the second terrace.

A battery system comprising:

• a battery including a base defining an internal volume configured to receive a battery cell and a lid coupled to the base, wherein:
• the lid includes a ledge extending past the base;
• the ledge includes:
• a first terrace extending from the ledge and at least partially defined by the base, wherein the first terrace is configured to provide access to a first electrode tab;
• and
• a second terrace extending from the ledge and at least partially defined by the base, wherein the second terrace is configured to provide access to
• a second electrode tab;
• and
• a module seated on the ledge between the first terrace and the second terrace.

A battery system comprising:

• a battery including a housing defining an internal volume configured to receive a battery cell and a ledge extending from the housing, wherein the ledge includes:
• a first terrace extending from the ledge and at least partially defined by the housing, wherein the first terrace is configured to provide access to a first electrode tab;
• and
• a second terrace extending from the ledge and at least partially defined by the housing, wherein the second terrace is configured to provide access to a second electrode tab;
• and
• a module seated on the ledge between the first terrace and the second terrace.
