Battery assembly with temperature control mechanism
First Claim
1. A battery assembly comprising:
- a stacked array of closely spaced unit batteries having first side walls disposed in mutually facing relation and second side walls facing outwardly of said battery assembly;
a plurality of heat-transfer plates each composed of a first heat-exchange planar member sandwiched between, and held against, first side walls of an adjacent pair of the unit batteries, and a second heat-exchange planar member integrally joined to said first heat-exchange planar member and projecting outwardly from the second side wall of at least one of the adjacent pair of the unit batteries;
holding means for holding said array of closely positioned unit batteries and said heat-transfer plates together; and
a temperature control mechanism for controlling a temperature of the unit batteries through a heat exchange carried out by said first heat-exchange planar members and said second heat-exchange planar members.

Abstract
A battery assembly has a temperature control mechanism for effecting cooling or heating unit batteries for operation in a desired temperature range. First heat-exchange planar members of respective heat-transfer plates are sandwiched between the unit batteries that are arranged in an array, and second heat-exchange planar members thereof are held against transverse narrow side walls of the unit batteries. The unit batteries and the heat-transfer plates are securely fastened together by holder plates. Heat produced when the unit batteries are in operation is transferred through the first and second heat-exchange planar members of the heat-transfer plates and dissipated into an appropriate cooling medium, such as atmospheric air or another cooling fluid, through a heat-exchange.
