Description

CHARGING DEVICE FOR COMPUTING APPLIANCES

FIELD OF DISCLOSURE

[0001] The present disclosure relates to the field of electrical appliances, and particularly to chargers for electrical devices. More particularly, the present disclosure relates to a portable electrical device that can be used to charge power source of any other electrical /electronic device in general, and portable communication devices and/or mobile phones in particular,through mains or without being connected with mains power supply source.

BACKGROUND OF THE DISCLOSURE

[0002] The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

[0003] Development in electrical power systems has brought around portability in existing electrical/electronic devices, be it simple illuminating devices such as torches, audio systems such as Ipods, communication devices such as mobile phones, or computing devices such as laptops, tablet PCs, among others. Such devices typically rely on batteries for their electrical power, especially when they are not connected to or cannot be powered through mains supply. These batteries however can supply power for a limited period of time and either need to be replaced or recharged. Periodic recharging of batteries can be done through battery chargers. Earlier, when the mobile phones were simple and were used only for calls and for sending and receiving SMSs, periodicity of recharging of batteries once in 24 hours was sufficient to ensure all time availability of the system. However, with the development of mobile phones into smart phones and computing devices that can be used as cameras, music systems, devices for playing games, devices for streaming and watching videos and movies, devices for use as mobile banks, etc., charging of batteries once a day does not suffice. Furthermore, it may be possible to every time find a mains supply source to charge our portable electronic devices. [0004] Battery charger solved one major problem by creating an ability to periodically extend life of power source of such electrical/electronic devices. However, frequent charging of power supply sources of portable devices directly through mains can lead to damage to the battery or even to the electrical device because of possible faulty connections or short circuiting or over voltage or over current.

[0005] There is therefore required a system and device that can be safely used for simultaneous charging, through main power supply, of a power supply source/battery as well as portable electrical devices that are being charged by the power supply source/battery.

SUMMARY OF THE DISCLOSURE

[00015] The present disclosure mainly relates to the field of electrical appliances, and particularly relates to electrical appliances having chargeable batteries that can be charged by means of a charging device. Although the present disclosure explains the portable electrical/electronic devices/appliances as being mobile phones, one should appreciate that any applicable portable electrical device such as Laptop, PC, Tablet, Smart Devices, among any other battery/non-battery operable and configurable device is completely within the scope of the present disclosure.

[00016] Furthermore, for clarity, in an aspect of the present disclosure, electronic devices such as mobile phones, smart phones, laptops, tablet PCs, among others being charged by the proposed charging device can be simply referred to as "end user devices" hereinafter, and should be interpreted to include computing/non-computing portable/non-portable devices/appliances that can be operably coupled with the proposed charging device to be charged.

[00017] In an aspect, the present disclosure relates to a charging device having an integrated battery therewith for charging one or more end user devices such as mobile phones/smart devices,making the charging device being operable to provide power to the end user devices even when the main power supply does not work or is not available so that the proposed charging device with integrated battery can be used to power the end user devices.

[00018] According to one embodiment, charging device of the present disclosure can be a portable device that can be used for charging batteries of end user devices in general,and mobile phones in particular, through mains power supply. According to another embodiment, the charging device can be used for charging batteries of end user devices even when the mains power supply is not available through its own integrated battery, wherein the integrated battery is simultaneously charged along with the end user devices when the charging device is connected with the main power supply. In an exemplary implementation, power supply source (such as battery) of an end user device can be run/operated through the power supply source(such as battery) of the proposed charging device.

FIGs. 2A, 2B, and 2G showan aspect of the charging device 102 having a plurality of female ports 106 (such as 106-1 and 106-2) that are configured to accommodate corresponding male ports of the charging wire such as 104.

[00063] According to another embodiment, charging device 102 of the present disclosure can also be configured to have an integral memory that can store a defined amount/size(depending on the size of the integral memory) of desired data/information such as software applications, audio/video files, softwares, among other content, wherein such data/content can be made accessible to the user that charges his/her computing device through the charging device 102 of the present disclosure.

[00064] In an aspect, of the present disclosure, the proposed charging device 102 enables simultaneous charging, wherein main power supply can give power to the internal battery Bl of the device 102 as well as to the battery B2 of the end user device so that both the batteries get charged simultaneously. Therefore, we a user has 1 hour of charging time, the end user such as mobile phone gets charged for 1 hour as well as the battery Bl of the proposed charging device 102 gets charged for 1 hour (1 amp + 1 amp) simultaneously, which means that after 1 hour, when the user takesthe charger 102 away from the end user device, the user has two hours of collective charge between the end user device and the charger 102. In an aspect, for a 2amp charger, 2amps can be split to 1 for the battery Bl and 1 for the end user device that is connected to the charger 102. In case multiple end-user devices are connected to the device 102, the 1 amp can be further split between the devices, however this is only an exemplary implementation and any other configurational change can be implemented, all of which would be within the scope of the present disclosure.

[00065] In another embodiment, device 102 can be configured with a communication interface such as a Wi-Fi interface or any other wireless/wired interface that enables communication with one or more user devices or with a central device such as a server. In an aspect, using the communication interface, device 102 can be controlled and/or configured for its charging pattern, or even its internal software can be upgraded. Furthermore, a log of all the activities performed by the device 102 can be generated, performance of the device 102 can be monitored, date of first use and abuse can be monitored, serial number can be accessed, and any other data related to the device 102 can be retrieved/assessed/controlled/managed.

[00066] In another aspect, USB ports on the device 102 can enable attachment to other accessories, wherein for instance, a mouse can be connected to one USB port 106-1 and mobile phone can be connected to the other USB port 106-2 in a manner such that the mouse can be used to maneuver on the interface of the mobile phone.

[00067] FIGs. 3 A to 3H illustrateexemplary representations of a battery integrated charging devicel02 having a storage unit, a wireless communication unit, and a battery unit that is integrated within the device 102 in accordance with an embodiment of the present disclosure. In an aspect, charging device 102 can include a plurality of USB ports such as USB port 106-1 and USB port 106-2, a microSD card slot 302, and pins 202, a wireless interface, and a battery unit (not shown). In an aspect, USB port 106-1 and 106-2 can be used for any or both of data transfer and/or for charging end user devices attached to the device 102. In an exemplary implementation, charging device 102 can be configured to simultaneously charge battery Bl that is be integrated within the charging device 102, along with the battery B2 of the end user device. In an exemplary implementation, charging device 102 can be configured to sense if any electronic device, such as a mobile phone, laptop, PDA etcis connected with it or not. In another aspect, charging device 102 can simultaneously charge the batteriesBl and B2 of both the charging device 102 as well as of the end user device, if any end user device is attached with it.

[00068] As one will appreciate, simultaneous charging of both batteries Bl and B2has its inherent advantage, wherein, for instance, if a user has access to the main power supply for only a limited period of time, charging device 102 can enable the user to simultaneously charge the battery of charging device 102 as well as of the end user device, wherein battery Bl of the charging device 102 can then later be used for charging battery B2 of the end user device.

[00069] In an exemplary implementation, with a bit of modification in the circuitry, charging device 102 can further be configured to charge batteries Bl and B2 in preferential manner.
