Thermally managed battery enclosure for electric and hybrid electric vehicles
First Claim
1. A thermally managed battery enclosure in a powered vehicle comprising:
- a) at least one cradle of thermally conductive material 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;
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, said passageway containing a pipe for flowing heating or cooling fluid therethrough;
d) said passageway trough being filled with a thermally conductive fill surrounding said pipe; and
,e) means for controlling the temperature of said fluid to maintain said battery in accordance with temperature requirements of said battery comprising at least one heat exchanger for obtaining heating or cooling fluid from heating and cooling systems, respectively, in said vehicle.

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
