E-cigarette and re-charging pack
First Claim
1. A rechargeable e-cigarette comprising:
- a battery;
a connector which is electrically connectable to an external battery pack; and
a recharging mechanism for re-charging the battery using the external battery pack when the connector is electrically connected to the external battery pack, the recharging mechanism comprising;
a charge controller for controlling electrical power flow from the external battery pack to the battery,a temperature sensor which is responsive to the temperature of the battery, anda timer;
wherein;
the charge controller is configured to prevent electrical power flow from the external battery pack to the battery when the temperature of the battery is determined to lie outside a range defined between a lower temperature threshold and an upper temperature threshold; and
the timer is configured to start timing when electrical power starts flowing from the external battery pack to the battery and to prevent electrical power flow from the external battery pack to the battery after a predetermined time period has elapsed.

Abstract
A pack for containing and recharging an e-cigarette includes: a re-chargeable 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 second connector which is electrically connectable to an e-cigarette contained within the pack; and a second recharging mechanism for re-charging the e-cigarette when the e-cigarette is electrically connected to the second connector. The first recharging mechanism includes a first protection circuit module and the second re-charging mechanism includes a second protection circuit module, wherein the protection modules protect the pack and e-cigarette against excessive voltage or current during re-charging.

6. A pack for containing and recharging an e-cigarette, the pack comprising:
-
a re-chargeable 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 second connector which is electrically connectable to an e-cigarette contained within the pack; and a second recharging mechanism for re-charging the e-cigarette when the e-cigarette is electrically connected to the second connector; wherein; the first recharging mechanism comprises; a first protection circuit module for preventing electrical power flow from the external power source to the pack battery when the current supplied to the pack battery exceeds a first predetermined current threshold or the voltage supplied to the pack battery exceeds a first predetermined voltage threshold; and the second re-charging mechanism comprises; a second protection circuit module, which sits between the first protection circuit module and the pack battery, for preventing electrical power flow from the pack battery to the e-cigarette when the current supplied by the packbattery exceeds a second predetermined current threshold or the voltage supplied by the pack battery exceeds a second predetermined voltage threshold. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)
