Battery pack including measuring and indicating
First Claim
1. A battery pack comprising:
- a casing adapted to be detachably attached to a battery-powered apparatus;
a rechargeable secondary battery housed within the casing and having positive and negative terminals;
only one pair of power electrodes connected respectively to the positive and negative terminals of the secondary battery and positioned on an outer surface of the casing so as to be electrically connected to the battery-powered apparatus, said electrodes being used both as recharge electrodes and discharge electrodes;
a measuring means provided within the casing for measuring the remaining amount of electric power of the secondary battery and generating at least one information signal related to the remaining amount of the electric power which has been measured;
at least one signal electrode provided on the outer surface of the casing and adapted to transfer the information signal generated from the measuring means to an apparatus to be connected to the battery pack; and
an indicating means provided on the outer surface of the casing for indicating information related to the remaining amount of the electric power of the secondary battery in accordance with the information signal generated from the measuring means.

Abstract
A battery pack including a casing adapted to be detachably attached to a battery-powered apparatus. A rechargeable secondary battery is housed within the casing and includes positive and negative terminals. At least a pair of power electrodes are connected to the positive and negative terminals of the secondary battery and positioned on an outer surface of the casing so as to be electrically connected to the battery-powered apparatus. A measuring circuit is provided within the casing for measuring the remaining amount of electric power in the secondary battery and generating one or more information signals related to the remaining amount of the electric power which has been measured. One or more signal electrodes are provided on the outer surface of the casing and adapted to transfer the information generated from the measuring circuit to an apparatus to be connected to the battery pack. In addition to or instead of the signal electrodes, an indicating unit may be provided for indicating information related to the remaining amount of the electric power of the secondary battery at the outer surface of the casing in accordance with the information signals generated from the measuring circuit.
