Battery module for vehicle energy-storage systems

A battery comprising a plurality of battery modules fluidically coupled in series along a linear liquid coolant flow path, each battery module of the plurality of battery modules fluidically coupled in series comprising:

• an enclosure having a base, the base having a plurality of first holes disposed therein, the base configured to support a plurality of cylindrical cells at a first end of each cell, the cylindrical cells having cylinder axes parallel to the linear liquid coolant flow path, the enclosure including a coolant input port and a coolant output port;
• the enclosure having a coolant sub-system for circulating coolant being directed into the enclosure through the coolant input port and the plurality of first holes and out of the enclosure through the coolant output port, wherein the enclosure further includes a channel connected to a channel of an adjacent one of the plurality of battery modules to define a contiguous linear portion of the linear liquid coolant flow path parallel to the cylinder axes of the cylindrical cells;
• a center divider affixed to the enclosure;
• a module cover coupled to the enclosure at an opposite end of the module from the center divider;
• a retainer coupled to the enclosure at a location within the enclosure and spaced from the base to define a coolant flow area, the retainer comprising a retainer plate having a plurality of circular retainer holes extending therethrough, the circular retainer holes configured to support the plurality of cells at a second end of each cell opposite the first end;
• a current carrier disposed between the module cover and the retainer;
• and
• the plurality of cells disposed between the current carrier and the center divider, the cells being coupled to and supported by the retainer.
