Battery housing systems

A battery module comprising:

• a housing having a length, a width, and a height, with the length being longer than the width and the height;
• the housing further including four sidewalls, a first open end, and a second open end opposite the first open end, the four sidewalls extending the length of the housing and forming a seamless closed channel member,
• the four sidewalls include a first sidewall and a second sidewall opposite one another and each including a plurality of protrusions, with all of the protrusions being offset between the first sidewall and the second sidewall, and
• the four sidewalls further include a third sidewall and a fourth sidewall opposite one another and each including an approximately flat outer surface;
• a plurality of battery cells stacked lengthwise within the housing;
• a first endplate coupled to the first open end of the housing;
• and
• a second endplate coupled to the second open end of the housing.

A battery pack comprising,

• a pack, having a front side and a back side, and a plurality of support members configured to receive a plurality of battery modules, wherein the battery modules include;
• a housing having a length, a width, and a height,
• the housing further including four sidewalls, a first open end, and a second open end opposite the first open end, the four sidewalls extending the length of the housing and forming a single, continuous, seamless member,
• a plurality of battery cells stacked lengthwise within the housing,
• a first endplate coupled to the first open end of the housing, and
• a second endplate coupled to the second open end of the housing;
• and
• cooling conduits located between the battery modules and structurally separate from the battery modules.
