Portable battery recharge station for secondary batteries
A system and method for recharging secondary batteries. One embodiment of the present invention comprises a supervisory circuit, a voltage converter, a portable power source, and one or more of a holder and a socket. The holder is adapted to receive a specific type of secondary battery of a portable device. The socket is adapted to mate with a plug of a device-specific charging cord connected to the portable device. Each of the holder and the plug can be associated with a programming resistor that provides a voltage requirement of the secondary battery. When the secondary battery is either placed in the holder or is connected to the socket, the supervisory circuit communicates with the voltage converter to supply the appropriate voltage required to recharge the secondary battery. The voltage converter receives power from the portable power source. The voltage converter can convert the voltage of the portable power source up (i.e., increasing the voltage) or down (i.e., decreasing the voltage) as appropriate to recharge the secondary battery as instructed by the supervisory circuit. The portable power source of the portable battery recharge station can be one of several types of power sources. For example, the portable power source can be replaceable, rechargeable, or renewable.
1. A portable battery recharge station comprising:
a socket;
a connector having a first end configured to mate with a device having a secondary battery and a second end configured to mate with the socket;
a supervisory circuit that determines a voltage requirement of the secondary battery based on an attribute of the connector when the connector is connected to the socket; and
a voltage converter in communication with the supervisory circuit and connected to the socket, wherein the supervisory circuit instructs the voltage converter to supply a voltage to the socket in accordance with the voltage requirement;
and wherein the voltage converter receives power from a power source.
2. The station of claim 1 wherein the attribute of the connector is a resistance.
3. the station of claim 1 , wherein the power source is an alternating current power source.
4. The station of claim 1 , wherein the power source is a direct current power source.
5. The station of claim 1 , wherein the power source is one of a replaceable battery, a rechargeable battery, a renewable battery, and a renewable fuel cell.
6. The station of claim 5 further comprising a reservoir adapted to contain fuel of the renewable battery and a gauge adapted to measure a level of the fuel.
7. A battery charging system comprising:
a charging connector having a first end that is configured to mate with a device having a secondary battery and having a second end;
a portable battery recharge station having a voltage converter and a supervisory circuit, the portable battery recharge station being configured to receive the second end of the charging connector, wherein when the charging connector is connected to the device and the portable battery recharge station, the supervisory circuit determines a voltage requirement of the secondary battery based on a resistance of the charging connector, and the supervisory circuit then instructs the voltage converter to supply a voltage to the secondary battery in accordance with the voltage requirement;
and wherein the voltage converter receives power from a power source.
8. The system of claim 7 , wherein the power source is an alternating current power source.
9. The system of claim 7 wherein the power source is a direct current power source.
10. The system of claim 7 wherein the power source is one of a replaceable battery, a rechargeable battery, a renewable battery, and a renewable fuel cell.
11. The system of claim 10 , wherein the replaceable battery is one of an alkaline battery, a lithium battery and a zinc-air battery.
12. The system of claim 10 , wherein the rechargeable battery is one of a NiCd battery, a NiH 2 battery, a NiMH battery, a Li-ion battery, a Li-polymer battery, a zinc-air battery, and a lead acid battery.
13. The system of claim 12 , further comprising a recharger connected to the portable power source, wherein the recharger is adapted to receive power from an external power source.
14. The system of claim 12 , wherein the renewable battery is one of a methanol fuel cell and a renewable electrolyte type cell.
