The patent application discusses a battery pack designed to power electronic devices efficiently and conveniently. With the proliferation of electronic devices such as smartphones, tablets, and laptops, there is a growing demand for portable power solutions. Traditional charging methods often involve cumbersome cables and bulky equipment, making them less practical for on-the-go use. The proposed battery pack addresses these issues by offering a compact design that is easy to attach and use with various electronic devices.
The battery pack includes a battery, control circuitry, and a coil for efficient power transfer. It can charge an electronic device until its battery is fully or partially charged, or simply provide enough power to keep the device operational. The control circuitry generates alternating currents in the coil, creating a magnetic field that induces currents in a corresponding coil within the device. This wireless charging capability enhances user convenience and eliminates the need for physical connectors.
A significant innovation is the use of magnets for attachment. The battery pack features magnets or magnet arrays that align with corresponding magnets in the device, ensuring secure attachment. To protect magnetically stored information such as credit cards, the magnetic field strength can be adjusted. This is achieved through an electromagnet or a moving magnet array that adjusts its position relative to the device's surface, enhancing magnetic attraction when needed.
The battery pack's design prioritizes ease of use and portability. It can be charged via wired or wireless methods, with LED indicators showing its charge status. The compact form factor ensures it does not obstruct device functionalities like cameras. Additionally, alignment features ensure proper orientation when attaching to devices. The design also incorporates elements to minimize interference with device operations, such as using specific colors or contours on the enclosure.
The battery pack supports advanced communication features through near-field communication (NFC) technology. Once attached, the electronic device can detect the battery pack using a magnetometer and initiate charging or other operations. NFC capabilities allow for two-way data communication between the battery pack and the device, enabling additional functionalities beyond mere charging. This integration of communication technology enhances the overall user experience by providing seamless interaction between devices.
