Abstract

Present embodiments include a series of lithium battery modules having a plurality of electrochemical cells having different electrical characteristics such as voltages and/or capacities. The battery modules are each constructed using components, architectures, production methods, among other things, in common with each other. The lithium ion battery modules may include a first battery module type having a first capacity and a first voltage, a second battery module type having a second capacity and a second voltage, and, in some embodiments, additional battery module types (e.g., a third battery module type having a third capacity and a third voltage) having different voltages and/or capacities. The lithium ion battery modules may all have the same footprint.

A method of manufacturing lithium ion battery modules, the method comprising:

providing a first battery module subassembly on a first manufacturing path, the first battery module subassembly including a first housing having a first dimension, a second dimension, and a third dimension;
providing a second battery module subassembly on a second manufacturing path different from the first manufacturing path, the second battery module subassembly including a second housing having the first dimension, the second dimension, and a fourth dimension different than the third dimension;
converging the first manufacturing path and the second manufacturing path to a battery cell positioning region that includes a common battery cell source;
at the battery cell positioning region,
placing a first plurality of battery cells from the common battery cell source in the first battery module subassembly, and
placing a second plurality of battery cells from the common battery cell source in the second battery module subassembly, wherein a number of the second plurality of battery cells is different from a number of the first plurality of battery cells;
diverging the first manufacturing path from the second manufacturing path after the battery cell positioning region;
at a first component integration region in the first manufacturing path, the first component integration region having a first component source, assembling a first component of the first component source with the first battery module subassembly;
at a second component integration region in the second manufacturing path, the second component integration region having a second component source different from the first component source, assembling a second component of the second component source with the second battery module subassembly;
and
concluding the first manufacturing path and the second manufacturing path to result in a first battery module and a second battery module.
