Abstract

A battery type identification system for determining the type of a selected battery and its operational status as a function of type. A battery has spaced bands of selected conductivity to define an identification code used to identify the battery. An appliance using batteries (e.g., a consumer product) includes an array of conductivity detectors spaced to engage corresponding battery identification bands. The battery types identification system determines battery kinds of predetermined type and then determines the voltage of the battery to assess its operability status.

Claims

1. An elongated battery having first and second electrically conductive (EC) ends of opposite electric polarity, said EC ends defining a longitudinal axis, and having a non-conductive outer surface region (NOSR) between said first and second EC ends, further including at least a single region (ASR) of electrically conductive material (ECM) secured externally to said NOSR and identifying the elongated battery as a particular kind of battery.

2. The elongated battery according to claim 1 wherein said ASR extends substantially longitudinally around said elongated battery.

3. The elongated battery according to claim 1 wherein each of said ASRs extend substantially around said NOSR.

4. The elongated battery according to claim 1 wherein said ASR includes at least first and second longitudinally separated bands for coded battery typing.

5. A non-rechargeable battery (NB) having first and second conductive ends (CEs) of opposite polarity and an outer surface (OS) between said first and second CEs, said outer surface (OS) defining at least a single non-conductive band having an edge extending around at least one of said first and second conductive ends, and said OS defining a plurality of battery type identification zones (BT IZs) extending longitudinally between said first and second CEs.

6. The NB according to claim 5 wherein each of said BTIZs define a substantially circumferential band around said outer surface.

7. The NB according to claim 6 wherein selected ones of said substantially circumferential bands are conductive.

8. The NB according to claim 6 wherein said BTIZs define at least a single binary identification code used for battery typing.

9. An appliance to be powered by at least a single internally mounted battery, each battery of said at least a single having spaced identification zones having individual selected electrical conductivity states, and first and second electrically opposite poles, said appliance comprising a containment structure (CS) defining mounting surface (IRS) for securing said at least a single battery, said CS defining an array of type detection elements spaced to permit electrical communication with corresponding ones of said spaced identification zones.

10. The appliance according to claim 9 further including a power detection element correctable to a selected one of said at least a single internally mounted battery.

11. The appliance according to claim 9 wherein said at least a single battery is secured to said appliance.
