Heated/cooled battery
First Claim
1. In a multicell, electric storage battery comprising a monobloc container having bottom, end and side walls defining a plurality of cell compartments, a cover for said container, a plurality of galvanic cell elements each housed in a separate cell compartment within said container, and an electrically nonconductive intercell partition engaging said side and bottom walls for separating one said cell compartment from the next, the improvement wherein said partition comprises first and second external faces on opposite sides thereof each of said faces confronting a one of said elements in an adjacent cell compartment, at least one liquid flow passage formed in said partition interjacent said faces, inlet means at one end of said passage for supplying liquid to said passage, outlet means at the other end of said passage for exhausting said liquid from said passage, and conduit means connected to said inlet and said outlet means for respectfully supplying and removing said liquid from said passage, whereby liquids can be circulated through said passages to add heat to or extract heat from within the innards of said battery directly through said faces.

Abstract
A temperature controllable electric storage battery having monobloc construction and including thin, planar, heat exchangers placed throughout the battery between the electrode plates thereof. Preferably, the heat exchangers will comprise the intercell partitions of the battery container and the liquid passages therein will have an elongated cross section in a direction transverse the passage so as to provide a wide passage having the majority of the surface defining the passage lying in planes substantially parallel to the external face of the heat exchangers.

In a multicell, electric storage battery comprising a monobloc container having bottom, end and side walls defining a plurality of cell compartments, a cover for said container, a plurality of galvanic cell elements each housed in a separate cell compartment within said container, and an electrically nonconductive intercell partition engaging said side and bottom walls for separating one said cell compartment from the next, the improvement wherein said partition comprises first and second external faces on opposite sides thereof each of said faces confronting a one of said elements in an adjacent cell compartment, at least one liquid flow passage formed in said partition interjacent said faces, inlet means at one end of said passage for supplying liquid to said passage, outlet means at the other end of said passage for exhausting said liquid from said passage, and conduit means connected to said inlet and said outlet means for respectfully supplying and removing said liquid from said passage, whereby liquids can be circulated through said passages to add heat to or extract heat from within the innards of said battery directly through said faces.
- 11. In a multicell, gas-recombinant, electric storage battery comprising a container, a plurality of galvanic cell elements each housed in a separate cell compartment of said container and comprising a plurality of opposite polarity plates alternately interspersed one with the other and spaced one from the other by an electrolyte-immobilizing mat, and an electrically nonconductive intercell partition separating one said cell compartment from the next, the improvement comprising a thin, substantially planar, liquid-cooled, heat exchanger disposed within each said cell compartment and lying in a plane substantially parallel to said partition, said heat exchanger having at least one external face confronting at least one said plate in said element in said compartment, at least one coolant flow passage disposed within said heat exchanger subjacent said face, inlet means at one end of said passage for supplying coolant to said passage, outlet means at the other end of said passage for exhausting said coolant from said passage, and conduit means connected to said inlet and said outlet means for supplying coolant to and removing coolant from said passages.
