Thermally managed battery enclosure for electric and hybrid electric vehicles
First Claim
1. A thermally managed enclosure for at least one battery comprising:
- a) at least one cradle of thermally conductive material for containing at least one battery;
b) said at least one cradle having a bottom wall and side walls closely fitted to and in contact with said at least one battery, wherein said side walls comprise a first set of parallel side walls and a second set of parallel side walls, said second set of side walls being of greater length than that of the first set;
c) the bottom wall of said at least one cradle having a passageway trough formed below said bottom wall, said bottom wall forming a top wall of said passageway containing a pipe for flowing heating or cooling fluid;
d) said passageway trough being filled with a thermally conductive fill surrounding said pipe;
e) said passageway trough being parallel to said second set of side walls; and
wherein the sidewalls having one or more apertures configured to receive one or more fasteners for securing the at least one battery to said battery enclosure.

Abstract
A thermally managed enclosure for batteries in a motor vehicle or other machinery includes a cradle of thermally conductive material for containing a battery. The cradle having a bottom wall and side walls closely fitted to and in contact with the battery, to maintain the battery in a stable position. The bottom wall of the cradle has a passageway trough containing a tube for flowing heating or cooling fluid therethrough, to control the optimal operating temperature of the battery. The passageway trough is preferably filled with a thermally conductive fill surrounding said tube. When two or more batteries are required, an array of adjacent cradles are provided in a monocoque tray formed by bonding or welding the multiple cradles at their adjacent sides. These cradles are optionally connected by linearly extending rods in the cradles.
