Four indicator lights are embedded in the top of one side of the testing body. A mounting sleeve is connected to one side of the top of the testing body. An audible and visual alarm is installed inside the mounting sleeve, with its top extending to the top of the mounting sleeve.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Please see Figures 1-3 A portable rapid testing system for string sodium-ion battery packs includes a testing body 1. A touch control panel 2 is embedded in the center of one side of the testing body 1. Four indicator lights 3 are embedded in the top of one side of the testing body 1. A mounting sleeve 5 is connected to one side of the top of the testing body 1. An audible and visual alarm 4 is installed inside the mounting sleeve 5. The top of the audible and visual alarm 4 extends through to the top of the mounting sleeve 5. The input terminals of the indicator lights 3 and the audible and visual alarm 4 are electrically connected to a control component 9. The output terminal of the control component 9 is electrically connected to the input terminal of the touch control panel 2. The output terminal of the control component 9 is electrically connected to an output bus 10. The output terminal of the output bus 10 is electrically connected to a server 11. The input terminal of the control component 9 is electrically connected to an external protection circuit board 8. The input terminals of the external protection circuit board 8 are electrically connected to a voltage acquisition sensor 6 and a temperature acquisition sensor 7, respectively. The control component 9 includes an isolation transformer 91, a converter 92, and a microcontroller 93. The wiring terminals of the voltage acquisition sensor 6 are connected to the positive and negative terminals of the sodium-ion battery pack through two wires.

[0022] As a technical optimization of the present invention, the four indicator lights 3 are evenly distributed from left to right, and the colors of the four indicator lights 3 are green, yellow, blue and red respectively.

[0023] As a technical optimization of the present invention, the isolation transformer 91, the converter 92 and the microcontroller 93 are all installed inside the detection body 1. The output terminal of the isolation transformer 91 is electrically connected to the input terminal of the converter 92, and the output terminal of the converter 92 is electrically connected to the input terminal of the microcontroller 93.

[0024] As a technical optimization of the present invention, the output terminal of the external protection circuit board 8 is electrically connected to the input terminal of the isolation transformer 91.

[0025] As a technical optimization of the present invention, the output terminal of the microcontroller 93 is electrically connected to the indicator light 3, the audible and visual alarm 4, the touch control panel 2, and the input terminal of the output bus 10, respectively.

[0026] Please see Figures 4-6 When the voltage sensor 6 and temperature sensor 7 detect a fault in a battery group (abnormal voltage or abnormal temperature), the device can display the serial number of the problematic battery group. The corresponding serial number of the battery group will flash continuously until the battery group fault is resolved. The changes in the collected voltage and temperature data can also be displayed through curves. The curves can be used to predict the trend of changes in the battery group earlier, ensuring the safe and stable operation of the battery.

[0027] This application employs a portable, small-scale housing structure, facilitating the inspection of both mobile and stationary sodium battery packs. Voltage sensors 6 collect the voltage of each battery string in real time, while temperature sensors 7 collect ambient temperature and humidity information. Battery pack data acquisition utilizes optocoupler isolation, ensuring noise-free, pollution-free, interference-resistant, and highly reliable operation. Battery inputs are protected by circuitry to prevent reverse connection damage. The system uses a serial port or Ethernet communication interface with protective isolation for input and output data. Furthermore, this application can simultaneously collect voltage (up to 32 channels), temperature (up to 16 channels), and ambient temperature and humidity information from multiple battery packs. The voltage measurement range is 0-12V, supporting up to 20 series-connected battery packs, and enabling network inspection of up to 64 battery packs.

[0028] In use, the output cables of the voltage acquisition sensor 6 and temperature acquisition sensor 7 are connected to quick connectors, which are then plugged into the external protection circuit board 8. Simultaneously, the input cable of the isolation transformer 91 is also connected to a quick connector, which is also plugged into the external protection circuit board 8, ensuring the accuracy of data acquisition and preventing damage to electronic components. Upon power-up, the device immediately acquires the voltage and temperature data of each branch of the sodium battery pack. The acquired data is automatically analyzed and calculated, allowing users to easily view the voltage and temperature of each battery group. All data types are displayed on the touch control panel 2, providing a clear overview of both summary and detailed data. If any data exceeds limits (including undervoltage, low voltage, high voltage, overvoltage, low temperature, and overtemperature), the device will automatically alarm, the corresponding indicator light 3 will illuminate, and the audible and visual alarm 4 will also provide warnings and reminders, ensuring the safety and stability of the power supply.

[0029] Voltage data (1-32 channels) and temperature data (1-16 channels) of each battery group are collected in real time using voltage sensor 6 and temperature sensor 7. The device operates in an environment with a temperature range of -10℃ to +40℃, measuring battery group voltage within a range of 0-12V. It supports 1-20 battery groups connected in series. Multiple battery groups / clusters can be monitored via Ethernet TCP / IP or serial port (485), supporting up to 64 battery groups for inspection and network-based cluster data acquisition. The data refresh rate is 1 second.

[0030] The number of battery strings can be arbitrarily set from 1 to 24, supporting rapid detection of up to 100 battery strings. The battery voltage measurement range is 0-12V, and the network detection cycle is less than or equal to 1 second. The data retention time is freely configurable, ranging from 1 second to more than 1 second. Stored data can be freely exported to an Excel spreadsheet for editing.

[0031] When multiple battery packs are networked, switches and routers can be flexibly configured according to the number of battery packs (1-100), and their respective IP addresses can be configured. The system connects to the network segment via Ethernet cable or fiber optic cable, and can collect and display all data within one second. The host computer manages the devices of different types of customers, categorizing each cluster and corresponding group. This allows for convenient querying, printing, and analysis of massive amounts of data.

[0032] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
