Abstract

A mains powered battery charger, for a mobile phone or any portable device, has a control circuit to control the power side of the circuit to switch it off when there is no load connected to it. The control circuit is activated again when a device is plugged into it. A capacitor uses stored energy to discharge into the device when it is connected, and a current measuring device senses the current flow and switches on the charger. The power used to switch the unit is from a built in rechargeable battery. In case of failure of the battery or capacitor, a manual backup pushbutton is supplied to close the contacts and activate the charger. The saving in power requirements countrywide could be as much as a 50 Mega watts of power equivalent to a small power station.

Description

Description of the Invention:
This invention is for an intelligent' Mobile phone or any disconnectable portable mains powered battery charger.
The unit will be constructed and will operate basically the same as a normal battery charger unit operates with the added facility of the Intelligent' feature.
The Intelligent' feature incorporates a simple electronic control circuit to control the power side of the charger and to switch this power connection off' when there is no load connected to it. The Load' refers to any portable battery powered device such as a mobile phone, ipod, or any other connectable device which requires to be charged from the mains supply.
The control circuit of the charger will be activated when a device is plugged into it, and will switch off when the device is disconnected from it.
How it will work:-The circuit will utilise a capacitor as stored energy which will discharge into the device when the device is connected to it, a simple current measuring device will sense this current flow and switch on the charger by switching the mains voltage to the main transformer on. The power required to switch the unit on will come from an in built re-chargeable lithium or alkaline battery (of non defined voltage) and will be kept fully charged whilst the charger is switched on, the capacitor will also be recharged once the charger powers up.
In the case of a total power failure from the capacitor and the lithium battery the unit will have a manual backup pushbutton, this will override the electrical circuit and manually close the main contacts, the unit will remain on once this action is carried out.
The charger will remain on and supply charge to the device, until the device is disconnected. On disconnection a sensor monitoring the current flow to the device
Description of the Invention: -cont' d
will sense the flow of current has ceased and will switch the main relay contacts off isolating it from the mains voltage.
The flow diagrams No I and 2 show the sequence of events from connection to disconnection and vice versa.
Iii Summary:-
The Intelligent' function will constantly monitor the power circuit output of the charger and sense the change in circuit current flow when the mobile phone or similar device is connected, this change in current will activatc an electronic relay on the primary side of the transformer thus beginning the charging of the unit plugged into it.
During charging, the charging cycle will be identical to a normal charger as this is not to be affected by this invention process.
On removal of the phone or device, again the sensing circuit will sense the change in the current flow to zero and will disconnect the mains power from the transformer.
The unit can then remain plugged into a power socket indefinitely with no power usage until a device is again plugged into it.

Claims (1)

  1. Claims of the Invention: The claim of the invention is to deal with the
    growing number of mobile phone chargers being plugged into the mains supply and not removed from the socket once the phone is fully charged.
    The design of this unit will allow the charger to be plugged into the mains supply constantly and without the need for removal once the unit being charged is disconnected from it.
    The power is effectively disconnected from the charger and thus has no standing load or standby transformer losses although only small in its own right, the accumulation of millions of these is having a devastating impact on the environment and the carbon emissions being produced just to power this standby load.
    The average mobile phone charger has a 6 millamp'standing load when there is no device connected to it Assuming there are 50% of the population who have a mobile phone, and 50% of those leave the charger plugged in constantly, this would equate to approx 17 million chargers on standby-load at any one time.
    17,000,000 x 6 milliamps = 102,000,000milli amps /1000 = I 02,000amps.
    Power (watts) = amps x volts 102,000 x 240v = 24,480,000 watts/1,000,000 = 24.5megga watts of power being wasted.
