초록 ▼

A device for testing a battery, particularly a small, portable battery, comprising a flexible, transparent substrate on which is deposited a narrow band of a black light absorbing material. A conductive material, which may taper outwardly in opposite directions from a central point to a pair of outer terminals, is then deposited atop the substrate on the same side of the substrate as the absorber layer or on the opposite side of the substrate as the absorber layer. A layer of a cholesteric liquid crystal material is then deposited on the substrate on the opposite side from the black absorber layer or over the absorber layer. The conductive material is an epoxy cement-based conductor, preferably silver, printed or painted directly on to the substrate. An indicator scale is located along sections of the conductive material. To test a dry cell battery, the terminal ends of the conductive material are placed in contact with the battery terminals, causing a current to flow which heats the conductive material, the heat generated being the most intense at the central point and radiating outwardly. The heat is transferred through the thin substrate to the liquid crystal layer which results in a color change in the liquid crystal. The traverse of the color change along the length of the indicator scale, outwardly from the center point, is proportional to the current or voltage output or the condition of the battery to be tested and can be read on the indicator scale which is calibrated accordingly. The tester also includes means for determining the amp-hours or life of a battery.

대표청구항 ▼

A battery tester which utilizes liquid crystal material that changes color proportional to the current produced by a battery being tested, said tester comprising: a substrate constructed of flexible material; at least one pattern of electrically conductive material having terminal end sections located on said substrate; and at least one layer of a cholesteric liquid crystal material located on said substrate and in alignment with and extending along a portion of said conductive material pattern; said substrate being constructed of material of sufficient flexibility to enable said terminal end sections of said electrically conductive material to be placed in contact with the terminals of an associated battery; scale means having calibration markings thereon for indicating the strength of an associated battery; and whereby contact of said terminal end sections with terminals of an associated battery to be tested causes a current to flow through said condutive material which causes portions of said conductive material to heat, the heat being transferred to said liquid crystal material causing said liquid crystal material to change color proportional to the current flowing through said conductive material.
