Abstract

A charging system (100) includes a charger unit (102) having a charge pocket (110) within which a plurality of replaceable pockets (104, 106, 108) can be inserted to charge various battery types and various battery configurations. The replaceable pockets (104, 106, 108) each contain a memory chip (112) for storing battery parameter information. The charger unit (102) charges the battery (302) based on the battery parameter information stored in the memory chip (112) of the replaceable pockets (104, 106, 108).

Claims

1. A battery charging system, comprising:

a charger unit; and

a replaceable pocket insertable into the charger unit, the replaceable pocket having a memory chip for storing battery parameter information, the charger unit charging a battery based on the battery parameter information stored in the memory chip of the replaceable pocket.

2. A battery charging system as described in claim 1, wherein the charging unit comprises a multi-unit charger.

3. A battery charging system as described in claim 1, wherein the charging unit comprises a single unit charger.

4. A battery charging system, comprising:

a charger unit having a charge pocket with interface contacts;

a replaceable pocket insertable into the charge pocket of the charger unit, the replaceable pocket comprising;

interface contacts corresponding with the interface contacts of the charger unit; and

a memory portion for storing predetermined battery parameter information, the memory portion downloading the predetermined battery parameter information to the charger unit when the replaceable pocket is inserted into the charge pocket of the charger.

5. A battery charging system as described in claim 4, wherein the charger is a multi-unit charger having a plurality of charge pockets for receiving a plurality of replaceable pockets.

6. A battery charger, comprising:

a charge pocket;

interface contacts within the charge pocket;

a replaceable pocket insertable into the charge pocket, the replaceable pocket for receiving a battery, the replaceable pocket including interface contacts for mating with the interface contacts of the charge pocket and also for mating with corresponding battery contacts of the battery, the replaceable pocket including a memory chip for storing battery parameter information, the battery parameter information being downloaded to the charger unit and the charger unit charging the battery based on the battery parameter information.
