The embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments and it is to be understood that the logical, mechanical and other changes may be made without departing from the scope of the embodiments. The following detailed description is therefore not to be taken in a limiting sense.

[00034] FIG. 1 illustrates a block diagram of architecture of the intelligent charger, according to one embodiment herein. With respect to FIG. 1, the charging adapter 100 comprises comprising an adapter circuit 102, a slot to connect a secondary power source 103 and a means (not shown) for cooling the adapter circuit and the secondary power source. The adapter circuit 102 comprises a voltage translator 104 and a current converter 105. The voltage translator 104 shifts a voltage level received from a main power supply 101. The current converter 105 works in conjunction with the voltage translator 104 to convert and Alternating Current to a Direct Current. The secondary power source is connected to the adapter circuit through the slot 103. The secondary power source is charged simultaneously with a load battery or a handheld device battery. The secondary power source acts as a primary power source in absence of a main power supply 101.

[00035] FIG. 2 illustrates a block diagram of an alternate architecture of the intelligent charger, according to one embodiment herein. With respect to FIG. 2, the intelligent battery charger comprises an adapter circuit 202. The adapter circuit 202 converts a fluctuating 220V alternating current from the main power supply 201 to a 12V Direct Current used to charge a load or a mobile battery 206. The adapter circuit 202 is further connected to the supplementary power supply unit 204 through a diode 203. The supplementary power supply unit 204 comprises a processor 208, a secondary power source 207, a charger display 211, a Global Subscriber Module (GSM) 209 and a GSM activation switch 210. The secondary power source 207 is connected to the main power supply 201 in parallel with adapter circuit 202. The secondary power source 207 acts as main power source in the absence of the main power supply unit 201. In this case both the adapter circuit 202 and the mobile 206 battery act as a load. To avoid a power flow towards the adapter circuit 202, the diode 203 is placed in the path that prevents a reverse current flow in absence of the main power supply 201.

[00036] The processor 208 is a specifically a 8-pin microprocessor. The secondary power source 207 is connected to the Vcc pins of the processor 208. The GSM activation switch 210 forms a unidirectional switch that connects/disconnects the GSM unit 209 with the processor 208. The GSM unit 209 is connected bi-directionally to an input pin and an output pin of the processor 208. The display unit 211 is connected to an output pin of the processor 208. The load device 206 is connected to an output pin and an input pin the processor 208 through a bi-directional bus 205. The bi-directional bus 205 is a Universal Serial Bus.

[00037] FIG. 2 A illustrates a front view of the intelligent charger, according to one embodiment herein. With respect to FIG. 2A, the display unit 211 shows a current time, a current date, a battery level of the mobile battery when it is connected for charging, a battery level of the secondary power source and a green or red light corresponding to on and off status of the GSM switch 210. The display unit 211 changes its colour on detecting a geo- location of a stolen mobile. [00038] FIG. 2B illustrates a side view of the intelligent charger, according to one embodiment herein. With respect to FIG. 2B, the side view comprises the GSM switch 210 and a 3 power pins 301.

[00039] According to an embodiment herein, the secondary power source acts as a load when connected to the main power and charges simultaneously with the mobile battery. The secondary power source acts as a source and charges the mobile battery till booth the battery level becomes equal. For e.g. after removing the main power supply the battery level of the secondary power source and the mobile battery is 100% and after a period of time the mobile battery is down to 53%. Then, a user directly plugs the charger to the mobile and the mobile battery will start charging through the secondary because secondary power source is at high potential. When the mobile battery level and secondary power source level reaches at same value i.e. 76.5%. The charger continuously shows an increasing of the mobile battery's level and decreasing of the secondary power source's level over the display.

[00040] According to an exemplary embodiment, the user creates a profile and registers an FMEI number of the mobile phone and a UIN of the battery in the profile and saves the information. The GSM module has functionality of sending and receiving information only to and from the mobile number with correlated IMEI number. As soon as, a mobile is lost the user activates the GSM module of the charger by pushing the GSM switch from "OFF" to "ON" position. As the GSM module is activated it initiates a ping to the server as well as the mobile phone. The GSM module continuously pings the mobile phone at every interval of 60 seconds. As soon as, the mobile phone is plugged to a charger with a charger with unrelated UIN or without an UIN, it receives a ping from the correlated battery charger. In return, the GSM reply with an acknowledgement and this process continues till the server tracks a geo-location of the mobile phone. The tracked geo-location is sent to the battery charger and the charger shows the notification of the found mobile through a faint red display. The user extracts the geo-location by logging to the server and reading a recent notification.

[00041] The smart charger in the present invention provides a mobile charging during travel or a place with unavailability of the main power supply. The smart charger also displays a plurality of useful information over its display unit. The smart charger also provides an anti-theft feature against the mobile phone theft.
