Detailed Embodiments

[0018] The features and exemplary embodiments of various aspects of the present utility model will be described in detail below. In order to make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present utility model can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present utility model by showing examples of the present utility model.

[0019] As Figure 1 , Figure 2 and Figure 3 shown, the present utility model provides a technical solution for an unattended battery charging and discharging device: It includes a charging and discharging machine body 1. A charging and discharging cabinet door 11 is provided on the front of the upper part of the charging and discharging machine body 1. The charging and discharging cabinet door 11 is movably connected to the charging and discharging machine body 1 through a hinge, and a pull handle 12 is installed on the charging and discharging cabinet door 11. A maintenance door 13 is provided at the lower part of the charging and discharging machine body 1. A plurality of rollers 14 are provided at the bottom corners of the charging and discharging machine body 1. Lifting lugs 15 are provided at the top corners of the charging and discharging machine body 1. A patrol inspection and safety component is provided inside the charging and discharging machine body 1;

[0020] The patrol inspection and safety component includes a host computer 2. A host computer control panel 21 is connected to the host computer 2. The host computer control panel 21 is installed on the charging and discharging machine body 1. The host computer 2 is sequentially connected to a DC voltage sensor 22, a DC current sensor 23, a 10-channel fully isolated battery patrol inspection instrument 24, a 5-channel temperature patrol inspection instrument 25, a temperature sensor 26, and a smoke sensor 27. The DC voltage sensor 22 is used to collect the charging and discharging voltage of the battery. The DC current sensor 23 is used to collect the charging and discharging current of the battery. The 10-channel fully isolated battery patrol inspection instrument 24 is used to collect the voltages of 10 groups of single batteries. The 5-channel temperature patrol inspection instrument 25 is equipped with a surface-mounted temperature probe and monitors the internal temperature of the battery pack. The temperature sensor 26 is used to collect the ambient temperature. The smoke sensor 27 is used to collect smoke information.

[0021] When in use, the user first sets the required charging and discharging parameters through the host computer control panel 21, such as the target voltage, current limit, and charging and discharging time, etc. Once the parameters are set, the entire charging and discharging process will be automatically started without manual intervention.

[0022] During the charging and discharging process, the DC voltage sensor 22 and the DC current sensor 23 continuously monitor the voltage and current changes of the battery pack to ensure that they are kept within a safe and efficient range. If any abnormal fluctuations are detected, such as overcharging, over-discharging, or excessive current, the system will immediately activate the protection mechanism, automatically adjust the charging and discharging strategy or abort the operation to prevent damage to the battery pack.

[0023] Meanwhile, the 10-channel fully isolated battery inspection instrument 24 works in parallel, precisely monitoring the voltage of each group of single cells. This high-precision monitoring helps to promptly detect and address the imbalance issues among single cells, improving the overall performance and lifespan of the battery pack. The 5-channel temperature inspection instrument 25, through its equipped patch temperature probes, penetrates deep into the battery pack to continuously monitor and record temperature changes, ensuring that the charging and discharging processes occur within an appropriate temperature range and avoiding potential safety hazards caused by excessive or insufficient temperature.

[0024] In addition, the temperature sensor 26 and the smoke sensor 27 are respectively responsible for monitoring the ambient temperature and smoke conditions around the device. Once the ambient temperature exceeds the normal range or a smoke signal is detected, the system will immediately issue an alarm and may trigger corresponding emergency measures, such as automatically cutting off the power supply or starting the exhaust system, to ensure the safety of the equipment and personnel.

[0025] During the entire charging and discharging process, the upper computer 2 serves as the control center, continuously collecting and analyzing data from various sensors, and real-time displaying the charging and discharging status, parameter changes, and any abnormal information. Users can remotely access the upper computer interface to view the charging and discharging progress, historical records, and alarm information at any time, realizing remote monitoring and management.

[0026] After the charging and discharging task is completed, the user can perform a shutdown operation through the control panel 21 of the upper computer, and the system will automatically save the charging and discharging data and turn off all devices. At this time, the user can perform subsequent processing or maintenance on the battery pack as needed.

[0027] The unattended battery charging and discharging device provided by the present utility model, with its intelligent inspection and safety components, remote control and monitoring functions, as well as high scalability and flexibility, not only significantly improves the efficiency and safety of battery charging and discharging, but also greatly reduces the labor cost and maintenance difficulty, providing a reliable solution for large-scale application scenarios in the civilian field.
