Description

Technical Field

[0001] This utility model relates to the field of electronic device battery maintenance technology, and in particular to a battery software upgrade device. Background Technology

[0002] With the widespread use of electronic devices, built-in batteries have become a core component of portable electronic products such as smartphones and tablets. These batteries are typically cube-shaped and contain a complex structure including battery cells, protection boards, battery management chips, and communication interfaces. To optimize battery performance, fix potential program defects, or expand functionality, battery manufacturers need to release corresponding firmware or software updates periodically. Currently, most smart batteries on the market are equipped with common communication interfaces such as I2C, providing a hardware foundation for software upgrades.

[0003] In the mobile phone repair industry, to ensure repair efficiency, repair shops typically need to keep a variety of commonly used battery models in stock. However, during storage, the software versions of these batteries may become outdated. Installing such batteries directly into user devices may result in suboptimal performance due to software incompatibility, or even compatibility issues, impacting user experience and potentially leading to further complaints.

[0004] Currently, the common practice for software upgrades on stock batteries involves repair personnel connecting the battery to a general-purpose computer (such as a personal computer or laptop) via a cable, then running a dedicated upgrade tool on the computer. The computer reads the upgrade file and writes the data to the battery. However, this general-purpose computer-based upgrade method has the following drawbacks: 1. Inflexible and inconvenient operation: The upgrade process relies on computer equipment, which restricts operation to a fixed workstation, making it difficult to move flexibly within the repair workshop or to work outside the workshop. Furthermore, the operation involves multiple steps, such as turning on the computer and launching the upgrade software, which is cumbersome and affects repair efficiency.

[0005] 2. High cost and significant resource consumption: The dedicated computer equipment for battery upgrades incurs a certain purchase cost and occupies workspace. During the upgrade process, the computer is unable to perform other tasks (such as information retrieval, parts ordering, work order processing, etc.), resulting in low resource utilization.

[0006] 3. Unintuitive human-computer interaction: Upgrade status information (such as progress, success / failure prompts) can only be displayed on the computer screen, and the information is easily obscured by other interfaces, making the prompts ineffective. Due to the lack of dedicated visual or audio-visual status indicators, maintenance personnel need to continuously monitor the screen, making it difficult to perform other maintenance tasks simultaneously.

[0007] 4. Insufficient specialization and integration: This solution essentially utilizes a general-purpose computer for data processing and is not specifically designed for battery upgrade scenarios. It lacks in areas such as secure storage of upgrade files, optimization of the upgrade process, and deep adaptation to battery communication protocols, resulting in a low overall level of integration and professionalism.

[0008] Therefore, how to provide a battery software upgrade device that improves the convenience, flexibility, and professionalism of battery software upgrades has become an urgent technical problem to be solved. Utility Model Content

[0019] The advantages of this utility model are: 1. By highly integrating the control module, storage module, power module, prompt module, and display module into a single portable device, the reliance on general-purpose computers is fundamentally eliminated, thereby significantly improving the convenience, flexibility, and professionalism of battery software upgrades. Its built-in power supply and storage module with embedded upgrade programs allow for "pick-up and use" operation anytime, anywhere, greatly simplifying the process and reducing costs. The dedicated programming interface JP1, communication module, prompt module, and display module constitute a deep optimization for battery upgrade scenarios. Hardware-level integration ensures operational reliability and intuitive interaction, achieving a fundamental leap from a general-purpose tool to a professional device.

[0020] 2. By integrating the control module, storage module, operation module, power module, prompt module, display module, and programming interface into one unit, a highly systematic battery software upgrade device is achieved. For example, the control module uses the microcontroller U1 as its core, along with an external resistor and capacitor network, to ensure the stability of signal processing. Furthermore, the clear pin connections between modules (such as the interconnection between the microcontroller U1 and the storage and operation modules) reduce external dependencies and wiring complexity. This integrated design not only reduces the device's size, making it easier to carry and deploy on-site, but also reduces the risk of misoperation through internal collaborative work, thus improving the reliability of the upgrade process.

[0021] 3. By equipping a display module (such as LCD1) and a prompt module (such as BUZ1 and LED1), real-time visual and auditory feedback is provided to the user. For example, the display module optimizes signal transmission through a resistor and capacitor network to ensure clear information display. The prompt module is directly driven by the microcontroller U1 and can issue prompts at key upgrade nodes (such as start, completion, or error). This design solves the problem of poor interactivity in traditional battery upgrade tools, making it easy for non-professionals to operate, reducing training costs and time, and reducing the upgrade error rate through intuitive feedback, thereby improving overall efficiency.

[0022] 4. The power module employs multiple protection circuits, including a charging management chip U3 and a linear regulator U4, combined with the battery BAT1, MOSFET, and dual-color LED2, to achieve wide voltage input and overcharge / over-discharge protection. Specifically, the linear regulator U4 provides clean power to the control module, while the charging management chip U3 optimizes battery life, ensuring continuous operation of the device during voltage fluctuations or power outages. This design avoids upgrade interruptions or data corruption due to power problems, enhancing the adaptability and durability of the device.

[0023] 5. Through the programming interface JP1 and optional communication modules (including the battery management unit and battery connection unit), the device is compatible with multiple communication protocols (such as through the Tyrp-C interface and the battery management chip U5). For example, the battery management unit supports data exchange with an external battery management system, while the battery connection unit uses a resistor network to achieve signal matching, ensuring compatibility with batteries from different brands. This flexibility allows the device to adapt to future battery technology iterations, supporting new protocols through software upgrades without hardware modifications, reducing long-term operating costs and expanding the scope of applications.

[0024] 6. A discrete modular structure is adopted (such as storage modules and control modules, which can be described and replaced independently). Each module is connected to the control module through a standard interface. For example, the storage module uses a dedicated chip U2 with a resistor-capacitor network, and the storage capacity can be upgraded separately without affecting the overall system. The switch and diode layout of the control module simplifies user input processing. This modularity not only simplifies the production and maintenance process and reduces life cycle costs, but also makes the device easy to customize (such as for optimization for specific battery types), enhancing market competitiveness.

[0025] 7. By integrating multiple protection components, such as MOSFETs, diodes, and battery management chips, into the power and communication modules, overcurrent, short circuits, or data conflicts can be prevented. For example, the battery management unit achieves soft start through transistors and inductors to avoid inrush current; the buzzer of the alert module can promptly alarm in case of abnormality. These features ensure the safety and data integrity of the battery software upgrade process and reduce the risk of equipment damage or personal injury.

[0026] 8. Through highly integrated modular design, control, storage, power supply, interaction, and communication functions are integrated in a coordinated manner, and a stable and reliable system is built with a microcontroller as the core. Its advantages lie in the improved maintainability and portability of the modular architecture, the robust power management scheme and multiple safety protection mechanisms to ensure the safety and continuity of upgrades under different operating conditions, the enhanced user interaction efficiency through intuitive display and prompt modules, and the compatibility with multiple battery protocols through flexible communication interfaces. Ultimately, a simple, adaptable, and easily expandable battery software upgrade solution is achieved, which significantly improves the reliability, safety, and overall performance of the upgrade process.

[0047] The power module supplies power to the entire device and consists of a charging management chip U3, a linear regulator U4, a battery BAT1, and peripheral circuitry. The charging management chip U3 manages the charging and discharging of battery BAT1, supporting wide voltage input and overcharge / over-discharge protection. The linear regulator U4 converts the battery voltage to a stable 3.3V or 5V, providing clean power to the control module and other components. During operation, when an external power source is connected, the charging management chip U3 charges the battery and indicates its status via a dual-color LED2.

[0058] Working principle of this utility model: Startup phase: The user starts the upgrade device by controlling the module buttons, the power module is activated, and the display module displays the standby interface.

[0059] Data reading: The control module loads the upgrade software from the storage module and performs verification.

[0060] Battery connection: The target battery is connected via the programming interface JP1 or the communication module.

[0061] Upgrade Programming: The control module writes the upgrade software into the battery, and provides real-time progress feedback through the prompt module (buzzer, LED) and display module.

[0063] In summary, the advantages of this utility model are as follows: 1. By highly integrating the control module, storage module, power module, prompt module, and display module into a single portable device, the reliance on general-purpose computers is fundamentally eliminated, thereby significantly improving the convenience, flexibility, and professionalism of battery software upgrades. Its built-in power supply and storage module with embedded upgrade programs allow for "pick-up and use" operation anytime, anywhere, greatly simplifying the process and reducing costs. The dedicated programming interface JP1, communication module, prompt module, and display module constitute a deep optimization for battery upgrade scenarios. Hardware-level integration ensures operational reliability and intuitive interaction, achieving a fundamental leap from a general-purpose tool to a professional device.

[0064] 2. By integrating the control module, storage module, operation module, power module, prompt module, display module, and programming interface into one unit, a highly systematic battery software upgrade device is achieved. For example, the control module uses the microcontroller U1 as its core, along with an external resistor and capacitor network, to ensure the stability of signal processing. Furthermore, the clear pin connections between modules (such as the interconnection between the microcontroller U1 and the storage and operation modules) reduce external dependencies and wiring complexity. This integrated design not only reduces the device's size, making it easier to carry and deploy on-site, but also reduces the risk of misoperation through internal collaborative work, thus improving the reliability of the upgrade process.

[0065] 3. By equipping a display module (such as LCD1) and a prompt module (such as BUZ1 and LED1), real-time visual and auditory feedback is provided to the user. For example, the display module optimizes signal transmission through a resistor and capacitor network to ensure clear information display. The prompt module is directly driven by the microcontroller U1 and can issue prompts at key upgrade nodes (such as start, completion, or error). This design solves the problem of poor interactivity in traditional battery upgrade tools, making it easy for non-professionals to operate, reducing training costs and time, and reducing the upgrade error rate through intuitive feedback, thereby improving overall efficiency.

[0066] 4. The power module employs multiple protection circuits, including a charging management chip U3 and a linear regulator U4, combined with the battery BAT1, MOSFET, and dual-color LED2, to achieve wide voltage input and overcharge / over-discharge protection. Specifically, the linear regulator U4 provides clean power to the control module, while the charging management chip U3 optimizes battery life, ensuring continuous operation of the device during voltage fluctuations or power outages. This design avoids upgrade interruptions or data corruption due to power problems, enhancing the adaptability and durability of the device.

[0067] 5. Through the programming interface JP1 and optional communication modules (including the battery management unit and battery connection unit), the device is compatible with multiple communication protocols (such as through the Tyrp-C interface and the battery management chip U5). For example, the battery management unit supports data exchange with an external battery management system, while the battery connection unit uses a resistor network to achieve signal matching, ensuring compatibility with batteries from different brands. This flexibility allows the device to adapt to future battery technology iterations, supporting new protocols through software upgrades without hardware modifications, reducing long-term operating costs and expanding the scope of applications.

[0068] 6. A discrete modular structure is adopted (such as storage modules and control modules, which can be described and replaced independently). Each module is connected to the control module through a standard interface. For example, the storage module uses a dedicated chip U2 with a resistor-capacitor network, and the storage capacity can be upgraded separately without affecting the overall system. The switch and diode layout of the control module simplifies user input processing. This modularity not only simplifies the production and maintenance process and reduces life cycle costs, but also makes the device easy to customize (such as for optimization for specific battery types), enhancing market competitiveness.

[0069] 7. By integrating multiple protection components, such as MOSFETs, diodes, and battery management chips, into the power and communication modules, overcurrent, short circuits, or data conflicts can be prevented. For example, the battery management unit achieves soft start through transistors and inductors to avoid inrush current; the buzzer of the alert module can promptly alarm in case of abnormality. These features ensure the safety and data integrity of the battery software upgrade process and reduce the risk of equipment damage or personal injury.

[0070] 8. Through highly integrated modular design, control, storage, power supply, interaction, and communication functions are integrated in a coordinated manner, and a stable and reliable system is built with a microcontroller as the core. Its advantages lie in the improved maintainability and portability of the modular architecture, the robust power management scheme and multiple safety protection mechanisms to ensure the safety and continuity of upgrades under different operating conditions, the enhanced user interaction efficiency through intuitive display and prompt modules, and the compatibility with multiple battery protocols through flexible communication interfaces. Ultimately, a simple, adaptable, and easily expandable battery software upgrade solution is achieved, which significantly improves the reliability, safety, and overall performance of the upgrade process.
