, Description:Field of Invention:
The present embodiment relates to mobile phone devices and their accessories and more particularly to a protective case / back cover panel for mobile phone device with an in-built surge battery recharging system.

Background of Invention:

In recent years, the use of mobile phone devices such as smartphones, tablet computers, personal digital assistants and other such devices has increased considerably, owing to their capacity to handle multiple tasks such as emails, editing calendars, managing appointments and reminders, browsing internet, watching videos, films, listening music etc. However, the traditional lithium-ion batteries that are used to power such devices haven’t been able to keep up in terms of their capacity, which is directly proportional to their size, so that they may last a whole day. Usually, such devices, especially smartphones, do not last a one full day i.e. 24 hours on a fully charged battery of any capacity. The general capacity that is used in smartphones ranges from 2000 mAh to 4000 mAh, with some exceptions, which, owing to the multiple tasks they are put to, doesn’t power them for more than 6-7 hours. This forces users to carry the chargers of their devices; battery packs etc., and charge the batteries at various establishments such as coffee shops, railway stations and basically hurts their flexibility and mobility.

In order to provide the users with an option to charge on-the-go, while they indulge in their day-to-day work, several mobile phone protective cases / back cover panels with inbuilt battery have been now made available in the market place. They come with battery capacity almost similar as the mobile phone device that they are enclosing. However, here too, the user needs to charge the mobile phone case / back cover panel on daily basis in the given duration and task of the day, it is imperative that there is healthy battery backup available in the mobile phone case / back cover panel, when it is not powering the mobile phone device.

Accordingly, there remains a need for mobile phone device cases / back cover panels with in-built charging and powering capacity and also be able to rely on other sources of energy on-the-go.

Summary of Invention:

In an aspect, a case / back cover panel for protecting and charging portable electronic devices is provided. The case / back cover panel includes: a number of photovoltaic cells arranged on an external surface of the case / back cover panel; anda first induction coil arranged on an internal surface and connected to the plurality of photovoltaic cells. The case / back cover panel further includes: a first battery connected to the first induction coil; a second battery; a second induction coil arranged on the second battery, for the second battery to receive charge from the first battery.

A mobile application or program is used to activate the first induction coil to charge the first battery, in turn the second battery through the second induction coil. The portable electronic device is a smartphone, a mobile phone, a tablet PC, or a personal digital assistant.

As mentioned, there remains a need for mobile phone device cases / back cover panels with in-built charging and powering capacity and also be able to rely on other sources of energy on-the-go, the embodiment herein, accordingly,relates to a protective cover or case / back cover panel, for a mobile phone device, with a battery capable of charging by solar energy. In an embodiment, the mobile phone device includes a smartphone, a personal digital assistant, a tablet PC, and other such portable electronic devices. In an embodiment, the protective cover or case / back cover panel is made up of any material such as plastic, metal, fibres or other commercially and popularly available material for such purposes and encloses the mobile phone device or such portable electronic devices for protection.

Fig. 1 illustrates a perspective view of back of a case / back cover panel 100 for a mobile phone device, according to an embodiment herein. The case / back cover panel 100 includes a number of photovoltaic cells 102 on anexternal surface to capture solar energy from the environment and a first battery 104. In an embodiment, the external surface includes external sides and external back surface of the case / back cover panel 100. The photovoltaic cells 102 may be arranged in any fashion or manner. In an embodiment, the photovoltaic cells 102 are applied on the back of the case / back cover panel 100 as a number of parallel strips of photovoltaic cells 102 as shown in Figure 2. The first battery 104 is powered by the photovoltaic cells arranged on an external surface of the case / back cover panel 100. The interior surface of the case / back cover panel consists of a first induction coil 202 which transmits power from the first battery 104. The switching ON and OFF of the induction coil 202 is controlled through a mobile application. The internal surface is the internal back surface of the case / back cover.
