E-cigarette and re-charging pack
First Claim
1. A rechargeable e-cigarette comprising:
- a battery which provides a voltage output that has a maximum level when the battery is fully charged;
a connector located on an exterior of the e-cigarette to allow the e-cigarette to be electrically connected to an external power supply for re-charging without disassembly of the e-cigarette; and
a recharging mechanism for re-charging the battery using power from the external power supply when the connector is electrically connected to the external power supply;
wherein the re-charging mechanism is configured to determine the voltage output of the battery, and to prevent re-charging of the battery if the voltage output of the battery is above a first predefined threshold level, wherein the first predefined threshold level is below the maximum level of the voltage output of the battery, wherein the first predefined threshold level (P) represents an offset (O) relative to the maximum voltage output level (M) of the battery, and wherein O=M−
P, and O is in a range of 0.075V to 0.3V.

Abstract
A rechargeable pack is provided for containing and recharging an e-cigarette. The pack includes a pack battery; a first connector which is electrically connectable to an external power source; a first recharging mechanism for re-charging the pack battery using the external power source when the first connector is electrically connected to the external power source; a tube for receiving an e-cigarette such that the e-cigarette can be contained within the recharging pack; a second connector which is electrically connectable to the e-cigarette when the e-cigarette is received within the tube; and a second recharging mechanism for re-charging the e-cigarette using the pack battery when the e-cigarette is electrically connected to the second connector. The second recharging mechanism is configured to provide protection against the pack battery providing excessive current through the second connector.
