Description

Technical Field

[0001] This invention relates to the field of power supply technology for mobile electronic devices, specifically to a mobile device powered by dual batteries independently and its power supply control method, applicable to all portable battery-powered electronic terminal devices. Background Technology

[0002] Currently, various mobile electronic devices (such as smartphones, tablets, laptops, smart wearables, handheld terminals, drones, etc.) all use a single-battery power supply mode, which has many unavoidable technical drawbacks: Firstly, once the battery is depleted, the device is forcibly shut down, core data is not saved in time and is easily lost, and basic functions such as emergency communication and positioning are completely interrupted, posing a great safety hazard. Secondly, a sudden battery failure or power outage during equipment operation can directly cause the entire machine to crash, posing a high risk of hardware and data damage. Third, the single-cell charge and discharge cycles are concentrated, the battery ages quickly, and it cannot achieve zoned power supply and redundancy protection; Fourthly, and most importantly, is the pain point most relevant to daily use: users only need basic functions such as calls, text messages, QR code scanning, payments, and access control, but they cannot use these functions when their phones suddenly lose power, causing great inconvenience to their lives, travel, and work. This is a common problem encountered by all mobile phone users.

[0003] Existing dual-battery solutions are mostly homogeneous redundancy, simply expanding capacity or parallel backup, without achieving truly independent power supply and functional division of labor. They cannot achieve zero-power standby for the main battery and ultra-low power long-term battery life for the secondary battery, nor can they achieve mass production without changing the mold, resulting in insufficient practicality and feasibility. Summary of the Invention I. Purpose of the Invention

[0004] This invention aims to overcome the shortcomings of existing single-battery and traditional dual-battery power supply schemes, and provides a dual-battery independent power supply mobile device and method based on heterogeneous redundancy, which realizes functions such as zero power consumption standby of the main battery, ultra-long offline standby of the secondary battery, and one-way protective power replenishment when the battery is low. It can be mass-produced without changing the existing equipment mold. II. Technical Solution 1. Product Solution

[0005] A mobile device powered by two independent batteries includes a main body, a main battery (11), a secondary battery (12), a power supply control module, and a partial screen lighting module (17). The main battery and the auxiliary battery are directly electrically connected without parallel or series connection, forming a heterogeneous redundant independent power supply structure. The main and auxiliary batteries can adopt an integrated structure or a separate independent structure: - Integrated structure: A physical isolation layer (22) is set in the same battery compartment to separate the main battery area (21) and the auxiliary battery area (23). - Separate structure: The main battery cell (31) and the auxiliary battery cell (32) are independent cells, distributed and installed independently, and can be disassembled and charged separately; The power supply control module integrates a status monitoring unit, a power supply switching unit, a data protection unit, and an anti-burn-in control unit to realize power supply mode switching and data protection. The display area of ​​the partial screen lighting module (17) accounts for less than 50% of the total screen. It has timed micro-movement anti-burn-in and anti-peeping functions and is used to light up the partial display area in the emergency power supply state of the auxiliary battery. 2. Methodology and Scheme

[0006] A dual-battery independent power supply control method includes the following steps: (1) Real-time monitoring of main battery status and equipment usage status; (2) Manually or automatically trigger entry into the secondary battery standby / emergency mode; (3) Cut off the main battery power supply to achieve zero power consumption standby of the main battery; (4) The auxiliary battery is independently powered and only runs offline lightweight firmware. It does not connect to the Internet and only drives basic functions such as communication, NFC, QR code scanning, payment, and access control. (5) Light up less than 50% of the screen and periodically move it slightly to prevent screen burn-in; (6) Maintain basic functions and achieve ultra-long offline standby time; (7) When the main battery is completely depleted, only 1% of its capacity is replenished. After replenishment, the main battery must not be discharged. (8) When the recovery conditions are met, the main battery power supply is switched back smoothly without data loss. Beneficial effects

[0007] Compared with the prior art, the present invention has the following advantages: 1. Heterogeneous redundant power supply improves equipment reliability: The main and auxiliary batteries are powered independently and do not interfere with each other, which solves the problem that a single battery failure will directly cause the whole machine to crash. At the same time, it avoids the structural defects of traditional homogeneous redundancy schemes and achieves true independent power supply redundancy protection.

[0008] 2. Ultra-low power standby, significantly improving emergency battery life: The main battery can achieve zero power consumption standby, and the secondary battery can support ultra-long offline standby. Even if the main battery is completely depleted, it can still maintain basic communication and payment functions, solving the core pain points of users' daily use.

[0009] 3. Low-power protective charging, balancing safety and practicality: When the main battery is depleted, only a small amount of power is added, which avoids damage from deep discharge of the main battery and prevents abnormal discharge of the main battery after charging from affecting emergency power supply, thus balancing battery life and emergency use scenarios.

[0010] 4. Partial screen illumination balances battery life and user experience: By illuminating only part of the screen and running lightweight firmware, the power consumption of the secondary battery is significantly reduced, while the privacy screen and screen burn-in prevention functions are retained, improving the user experience in emergency mode.

[0011] 5. High adaptability and low mass production cost: The solution does not require modification of existing equipment molds and can be directly adapted to various mobile devices such as mobile phones, tablets, smartwatches, law enforcement recorders, and drones. It has low mass production difficulty and high promotion potential. Attached Figure Description

[0013] Example 1: Integrated Dual Battery (Mobile Phone) Combination Figure 1 , Figure 2 , Figure 4 In this embodiment, a smartphone adopts an integrated dual-battery structure. The main battery area (21) and the secondary battery area (23) are separated by a physical isolation layer (22) within the same battery compartment. The main battery (11) and the secondary battery (12) are completely independent.

[0014] Under normal conditions, it is powered by the main battery, which meets the requirements for full functionality.

[0015] When the main battery is low, malfunctioning, or powered off, or when the user manually or the device automatically enters standby mode, the power supply switching module (13) immediately cuts off the main battery circuit, and the main battery consumes 0 power.

[0016] When the secondary battery (12) is activated, it does not run the main system, but only drives the partial screen lighting module (17) to light up <50% of the screen. The screen is periodically shifted to prevent burn-in, and offline QR code (42) and emergency prompts (43) are displayed. At the same time, it maintains call, SMS, NFC, payment and access control functions and can standby for about 15 days.

[0017] Only when the main battery is completely depleted should 1% of the charge be applied; after applying the charge, discharging is prohibited.

[0018] This embodiment requires no modification to the original mobile phone mold and can be directly mass-produced.

[0019] Example 2: Detachable Dual Battery (Tablet / Wearable / Industrial Device) Combination Figure 1 , Figure 3 , Figure 4 In this embodiment, a separate dual battery is used, with the main battery cell (31) and the auxiliary battery cell (32) installed independently and can be disassembled and charged separately.

[0020] The power supply logic, emergency mode, zero-power standby, ultra-long standby, partial screen, anti-burn-in, 1% power replenishment, data protection, and mass production without mold modification are all completely consistent with Example 1.

[0021] The secondary battery can achieve an ultra-long offline standby time based on the device's power consumption and usage scenario, meeting the basic functional requirements in emergency situations.

[0022] It is suitable for a wide range of devices, including tablets, smartwatches, law enforcement recorders, drones, POS machines, and industrial handheld terminals.
