Abstract
Abstract In an arctic military vehicle, one or more heating units is/are positioned against the outer surface of the battery to heat the battery electrolyte and thereby improve battery output capability during the critical engine start-up period. Each heating unit includes an internal self-contained heat source, thereby enabling the system to be used in wilderness areas remote from building energy sources. The invention is particularly applicable to arctic military vehicles that might be required to move through relatively uninhabited enemy areas where stationary energy sources might be unknown or non-existent.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
106 words
In an arctic vehicle equipped with battery ignition: the improvement comprising means for heating the vehicle battery to improve its electrical output energy capability preparatory to start-up of the vehicle, said heating means comprising at least one catalytic heater positionable in close adjacency to an outer side surface of the battery casing for directing heat energy through said casing into the battery electrolyte, an upright battery-reception box having sidewalls thereof spaced from the battery casing surfaces to form passages for heated gases flowing upwardly from the catalytic heater, and means forming gas escape openings therein tending to confine hot gases to the space surrounding the battery.
Claim 2
Dependent Claim
106 words

Claim 3
Dependent Claim
21 words
In the arctic vehicle of claim 1: the improvement further comprising a cover for the box, said cover overlying the battery.
Claim 4
Dependent Claim
38 words
In the arctic vehicle of claim 2: the further improvement wherein the catalytic heater is disposed within the box directly below the battery so that the heater generates heated gases in the space beneath the battery bottom wall.
Claim 5
Dependent Claim
54 words
In the arctic vehicle of claim 3: the further improvement wherein the box is provided with an access opening that accommodates placement of the heater in its operating position without removal of the battery from the box, whereby the heater can be taken out of the box when no longer needed for battery-heating purposes.
Claim 6
Dependent Claim
63 words
In the arctic vehicle of claim 4: the further improvement wherein the catalytic heater comprises a fuel container having a number of fuel escape ports in its upper wall, a fuel-adsorbent wick above each port, and a wire gauze flame holder surrounding each wick, each flame holder being formed of a metal that acts as a catalyst for flameless combustion of the fuel.
