[0046] The following provides numerous different embodiments or examples for implementing various features of the provided invention. The embodiments of components and configurations described below are merely examples and are not intended to be limiting. Furthermore, for simplicity and clarity, reference numerals and / or designations are repeated in the examples, but this does not in itself limit the relationship between the various embodiments and / or components discussed.

[0047] The terms "first," "second," etc., used in this article do not specifically refer to order or sequence; they are merely used to distinguish elements or operations described using the same technical terms.

[0048] Please refer to Figure 1 , Figure 2 As shown, Figure 1 It illustrates a functional block diagram of a portable diagnostic platform 100 according to an embodiment of the present invention. Figure 2 A schematic diagram of the daisy-chain data logger 110 is shown. The portable diagnostic platform 100 includes a daisy-chain data logger 110, which comprises a microcontroller main chip 1101 and a multi-channel daisy-chain bridging chip 1102 electrically connected to the microcontroller main chip 1101. The daisy-chain data logger 110 is electrically connected to the slave control unit 1202 of an external battery module 1201 via the multi-channel daisy-chain bridging chip 1102, and is used to read one or more of the cell voltage, current, and temperature signals from one or more battery modules, perform analysis and processing, and identify abnormal data, etc. In one embodiment, the multi-channel daisy-chain bridging chip 1102 is configured as a dual-channel daisy chain, allowing communication with the slave control unit via the dual-channel daisy-chain.

[0049] In this embodiment, the daisy-chain data logger is an important component of the battery management system (BMS). During the testing of the energy storage fixture, the daisy-chain data logger connects to the slave control unit and the fixture to achieve some of the functions of the master controller. The daisy-chain data logger has reliable data communication capabilities, enabling communication with the slave control unit of the battery management system or other necessary devices during system operation. In this embodiment, the daisy-chain data logger 110 serves as the core component of the portable diagnostic platform, with a highly sophisticated and powerful internal structure. The data logger is centered around a microcontroller chip 1101, which acts as the "brain" of the entire data logger, responsible for processing, controlling, and coordinating various functions. The microcontroller chip 1101, with its powerful computing capabilities and rich peripheral interfaces, can efficiently manage the various tasks of the data logger. Closely connected to the microcontroller chip 1101 is a multi-channel daisy-chain bridge chip 1102, which acts as a bridge between the data logger and the external battery module slave control unit 120, enabling electrical connection and smooth data transmission. The multi-channel daisy-chain bridging chip 1102 not only supports parallel communication across multiple channels but also allows for flexible configuration of the number of channels to meet the monitoring needs of battery modules of different sizes. Through this ingenious design, the daisy-chain data acquisition unit 110 can easily establish a connection with the slave control unit 1202 of the external battery module 1201. Once connected, the data acquisition unit can quickly read and analyze the cell voltage, current, and temperature signals of single or multiple battery modules, identifying abnormal data. This crucial data is essential for assessing the operating status of the battery module, predicting potential faults, and optimizing battery management strategies.

[0050] It's worth noting that this daisy-chain data collector design also grants it high scalability and flexibility. Whether dealing with small battery modules or large battery packs, different monitoring needs can be easily adapted simply by increasing or decreasing the number of daisy-chain bridging chips. This modular and scalable design not only reduces system complexity and cost but also significantly improves system reliability and maintainability.

[0051] Further reference Figure 2 As shown, in one embodiment, the daisy-chain data collector 110 is further provided with a USB interface 1103, through which it communicates with the host computer 130 or provides external low-voltage power, such as 5V. In one embodiment, the daisy-chain data collector is further provided with a DC24V interface for providing external 24V power.

[0052] Further reference Figure 2 As shown, the daisy-chain data collector 110 also has a reserved CAN communication interface 1104, which enables intranet CAN bus communication, achieving efficient data transmission and sharing. For example, the daisy-chain data collector 110 can also communicate with the slave control unit 1202 via the CAN communication interface 1104, which undoubtedly enhances the flexibility and reliability of the entire diagnostic system.

[0053] Further reference Figure 2 As shown, the daisy-chain data acquisition unit 110 is also equipped with a two-channel optocoupler input interface 1105 and a two-channel optocoupler output interface 1106. The design of these optocoupler interfaces enables the daisy-chain data acquisition unit to transmit signals more flexibly and reliably with other devices, effectively isolating electrical interference between different devices and improving the stability of the entire system. In addition, the daisy-chain data acquisition unit 110 is also equipped with a two-channel RS485 interface 1107. RS485, as a commonly used serial communication interface, has advantages such as long transmission distance and strong anti-interference capability. This allows the daisy-chain data acquisition unit to connect with devices that support RS485 communication, further expanding the application scenarios and compatibility of the entire diagnostic system.

[0054] Further reference Figure 1In one embodiment, the portable diagnostic platform 110 also integrates a main power supply 140 and a backup power supply 150. The main power supply 140 and backup power supply 150 are electrically connected to the daisy-chain collector 110 via a power conversion board 160 to provide power. In one embodiment, both the main power supply and backup power supply can be portable power sources, such as power banks. By integrating the main power supply 140, backup power supply 150, and power conversion board 160, the portable diagnostic platform 110 constructs a stable and reliable power supply system. This system not only ensures the continuous operation of the platform under various working conditions but also enhances its practicality and flexibility through its portable design. Through the power conversion board 160, these two power supplies can be efficiently electrically connected to the daisy-chain collector 110, ensuring that the platform receives a stable and reliable power supply in various working environments. The main power supply 140, as the primary energy source, bears the heavy responsibility of providing the portable diagnostic platform with the daily power required. In certain special circumstances, such as when the main power supply runs out or becomes unavailable, the backup power supply 150 can immediately take over, ensuring the platform's continuous operation and preventing diagnostic interruptions or data loss due to power outages. It's worth noting that both the main and backup power supplies are designed to be portable, meaning they are not only easy to carry but also can be flexibly switched and used in different working scenarios. This design greatly enhances the portability and adaptability of the portable diagnostic platform, enabling it to perform optimally in various complex environments.

[0055] In one embodiment, further reference is made to Figure 3 As shown, Figure 3 A schematic diagram of the overall structure of the portable diagnostic platform 100 is shown. The portable diagnostic platform 100 is integrated as a box-type diagnostic instrument; the outer casing of the box is not shown in the diagram for ease of observation of the internal structure. The portable diagnostic platform 100 includes a platform body 170, with a platform support 1701 mounted on the bottom of the platform body 170. The daisy-chain collector 110 and the power conversion board 160 are mounted on the platform support 1701. Furthermore, an opening 1702 is provided on the platform body 170, within which the main power supply 140 and the backup power supply 150 are placed, with the bottom ends of the main power supply 140 and the backup power supply 150 resting on the platform support 1701.

[0056] Furthermore, in one embodiment, further reference is made to Figure 3As shown, the platform body 170 is equipped with a display screen 1703. Users can easily view real-time data of the battery module, understanding its health status, remaining charge, and whether maintenance or replacement is needed. During diagnostics, the display screen also provides detailed error information, fault codes, and suggested solutions to help users quickly locate problems and take appropriate measures. Furthermore, the display screen 1703 supports touch or button operation, allowing users to switch display interfaces, adjust parameter settings, or execute diagnostic commands through simple touch or button presses.

[0057] Furthermore, in one embodiment, further reference is made to Figure 3 As shown, the platform body 170 is equipped with a power indicator light 1704, an alarm indicator light 1705, an external power interface 1706, a USB interface 1707, etc. The external power interface 1706 provides a connection channel for the platform to an external power source. Through this interface, users can connect the platform to a power adapter or power bank to ensure a stable power supply during extended use. This design makes the platform more portable and practical, easily usable in both indoor and outdoor environments. The USB interface 1707 further expands the platform's connectivity and application scenarios. Users can connect the platform to a host computer, barcode scanner, or other external devices via the USB interface to perform data transfer and other operations. This design not only facilitates data processing and management for users but also improves the platform's compatibility and scalability.

[0058] Furthermore, in one embodiment, reference Figure 1 As shown, the portable diagnostic platform 110 also integrates a barcode scanner 180, which is electrically connected to the platform body 170. In one embodiment, the barcode scanner 180 is equipped with a USB interface, a wireless communication interface, etc., and the portable diagnostic platform 110 may further integrate a wireless communication module. The barcode scanner is used to scan the QR code information of the battery module. The integration of the barcode scanner will enable the portable diagnostic platform 110 to obtain information about the battery module more conveniently. By scanning the QR code on the battery module, the platform can automatically obtain key information such as the module's model, specifications, and production date, without requiring manual input or searching by the user. This not only improves the efficiency and accuracy of diagnosis but also reduces the possibility of human error.

[0059] In summary, the portable diagnostic platform provided by this invention integrates the power supply, daisy-chain data logger, and barcode scanner into a unified platform with a box-like structure, making it easy to carry. During testing, the portable diagnostic platform is electrically connected to the slave control unit of the battery management system, enabling efficient reading and measurement of module voltage, current, temperature, and other signals. The multi-channel daisy-chain bridging chip of the daisy-chain data logger acts as a bridge between the data logger and the external battery module slave control unit, achieving electrical connection and smooth data transmission. The multi-channel daisy-chain bridging chip not only supports parallel communication of multiple channels but also allows for flexible configuration of the number of channels according to actual needs, thereby meeting the monitoring requirements of battery modules of different sizes.
