Abstract

A battery charger obtains parameter values derived from communication from a battery pack being charged. The battery pack has at least one rechargeable cell, a semiconductor device that stores the charging parameters for the rechargeable cell and communication bus configured to communicate with a battery charger device. The battery pack may have an identification number. A lack of communication between the battery pack and a charger may invoke a default charging program or denial of access to the charger.

Claims

1. A rechargeable battery pack comprising:

at least on rechargeable batter cell;

at least one sensor selected from the group consisting of a temperature sensor, a current sensor and a voltage sensor, or combination thereof, capable of generating dynamic data concerning said rechargeable battery pack;

a semiconductor memory affixed to said rechargeable battery pack capable of storing a plurality of data bits indicative of at least one charging parameter of said rechargeable battery pack and a digital representation of said generated dynamic data concerning said rechargeable battery pack;

a communication bus configured to transmit at least some of the data bits concerning said rechargeable battery pack that are stored within the semiconductor memory.

2. The rechargeable battery pack of claim 1, wherein said semiconductor memory comprises at least on location holding a presorted serial number.

3. A rechargeable battery device comprising:

at least one rechargeable battery cell;

sensor means configured to monitor a physical attribute of said at least one rechargeable battery cell;

a digital memory comprising a battery pack ID, and charging parameter values; and

connections for said at least one rechargeable battery cell, said sensor means, and said digital memory to connect to another device.

4. The rechargeable battery device of claim 3, wherein said digital memory is part of a module.

5. The rechargeable battery device of claim 3, wherein said sensor means comprises a volt sensor.

6. A rechargeable battery pack, comprising:

a rechargeable battery cell;

a memory device configured to store charging parameters for said rechargeable battery cell;

connections for said rechargeable battery cell and said memory device to connect to another device.

7. The rechargeable battery pack of claim 6, wherein said another device is a battery charger device.
