Abstract

A vending machine (10) for vending a rechargeable battery pack has a interface unit (12), new battery reservoir (14), battery dispensing unit (16), and a control unit (18). A customer interested in purchasing a new battery insets a payment in the money handling unit (30). A display (32) is provided and prompts the customer for a response. The customer responds by use of an entry pad (3), and the machine dispenses a new battery. Alternatively, if the customer is interested in exchanging a discharged battery for a fully charged one of similar condition, a battery pack received unit (20) is provided with a receiver port (42) for the customer to insert the spent battery. The spent battery is quickly analyzed by a battery test unit (22) and assigned a grade. If the spent battery is in usable condition, it is passed to a battery recharger, and the customer is prompted to choose between a new battery and one of similar grade to that deposited. If a new battery is selected, one is dispensed, as before. If a similar battery is requested, then one is located in the recharged battery reservoir (26), and dispensed. The price charged to the customer is proportional to the difference in grade between the battery deposited and the battery dispensed. If the battery is in an unusable condition, the customer may choose to have it returned, or may choose for the machine to retain the battery in an internal recycle bin so that the battery may be collected for recycling. Additionally, the machine may have a communications relay station mounted on it for short range wireless communications systems.

Claims

1. A vending machine for vending a rechargeable battery pack having a means for receiving a payment and generating payment information, a selection entry means for generating selection information, a battery pack storage space, and a means for dispensing said rechargeable battery pack, said vending machine comprising:

control unit having a memory, at least a portion of said memory containing instruction code;

battery pack receiver unit, responsive to said control unit, for accepting a received battery pack, said received battery pack having a voltage level;

test unit, responsive to said control unit, for testing said received battery pack and generating test information, said test information being signaled to said control unit;

recharging unit, responsive to said control unit, for recharging said received battery pack, thereby providing a recharged battery pack;

battery pack handling mechanism, responsive to said control unit, for moving said recharged battery pack to a location in said battery storage space; and

wherein said control unit controls the operation of said vending machine according to said instruction code.

2. A vending machine as recited in claim 1, wherein said battery pack receiver unit comprises a battery pack receiver unit port having a battery holder wherein said received battery pack may be inserted.

3. A vending machine as recited in claim 1, wherein said test unit comprises:

voltage measurement means for monitoring said voltage level of said received battery pack;

a load switchably applied to said received battery pack to produce a load response of said voltage level; and

wherein said test unit measures said load response of said voltage level to generate said test information.

4. A vending machine as recited in claim 1, wherein said test unit assigns a grade to said received battery pack based on said test information, said grade and said location in said battery storage space are recorded in said memory of said control unit.

5. A vending machine as recited in claim 1, wherein said recharging unit further comprises a discharge regulator whereby said received battery pack may be reconditioned.

6. A vending machine as recited in claim 1, wherein said vending machine is connected to at least one telephone line and further comprising a communications relay station connected to said at least one telephone line for allowing two way wireless communication.

7. A vending machine for vending a rechargeable battery pack, comprising:

control unit having a memory, at least a portion of said memory containing instruction code;

money handling unit, responsive to said control unit, for receiving a payment and generating payment information, said payment information being signaled to said control unit;

interface unit, responsive to said control unit, for displaying alternative operations said vending machine may perform and providing a selection entry means whereby a selection of one of said alternative operations may be entered, thereby generating selection information, said selection information being signaled to said control unit;

battery pack storage space for storing said rechargeable battery pack;

dispensing unit, responsive to said control unit, for moving said rechargeable battery pack from said battery pack storage space to a delivery bin;

battery pack receiver unit, responsive to said control unit, for accepting a received battery pack, said received battery pack having a voltage level;

test unit, responsive to said control unit, for testing said received battery pack and generating test information, said test information being signaled to said control unit;

recharging unit, responsive to said control unit, for recharging said received battery pack, thereby providing a recharged battery pack;

battery pack handling mechanism, responsive to said control unit, for moving said battery pack within said vending machine as directed by said control unit; and

wherein said control unit processes said payment, selection, and test information and controls the operation of said vending machine according to said instruction code.

8. A vending machine as recited in claim 7 further comprising a battery recycle bin for storing a received battery pack.

9. A vending machine as recited in claim 7 further comprising a discharge regulator responsive to said control unit and coupled with said recharging unit for discharging said received battery pack wherein said discharge regulator and said recharging unit function cooperatively to recondition said received battery pack.

10. A vending machine as recited in claim 7, wherein said money handling unit comprises a coin slot for receiving coins and a bill slot for receiving bills, wherein said money handling unit accumulates a count of said coins and said bills for generating said payment information.
