However, current monitoring and capacity verification management of battery packs often suffer from the following deficiencies:

[0003] The inherent on-site operation and maintenance model for batteries cannot meet the needs of professional development and improved system safety and reliability.

[0028] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1 The embodiment provides an online capacity verification and monitoring system for a battery pack at a power generation side boost station, including:

[0030] Data acquisition and transmission module: used to collect operating data through sensors installed on the battery pack;

[0031] The data acquisition and transmission module includes:

[0032] Single cell data collection unit: used to be installed on each battery in the battery pack to collect battery voltage, internal resistance and temperature data of positive / negative poles;

[0033] Convergence unit: used to collect the voltage, internal resistance and temperature data of each battery during operation collected by each single collection unit through RS485 line, and transmit the battery operation data to the remote monitoring center through wireless communication;

[0034] Remote monitoring module: remotely monitor the battery pack through the monitoring center, including viewing real-time operating data and remotely controlling charging and discharging;

[0035] Core capacity control module: performs online voltage boosting or inverter discharge on the battery pack through the core capacity device.

[0036] Specifically, the individual acquisition units in the data acquisition and transmission module accurately collect voltage, internal resistance, and temperature data for each battery cell, providing reliable data support for subsequent monitoring and management. The confluence unit aggregates data from each individual acquisition unit via an RS485 line, enabling centralized data management and transmission, improving data transmission efficiency and accuracy. The conversion unit converts analog signals into digital signals, enhancing data transmission stability and reliability while reducing data processing complexity.

[0037] Specifically, the remote monitoring module's monitoring center can view real-time battery pack operating data, including voltage, internal resistance, and temperature, providing comprehensive information support to management personnel. The capacity control module uses a capacity control device to perform online voltage boosting or inverting discharge on the battery pack, enabling charge and discharge testing of the battery pack, thereby achieving remote capacity control. The regulation unit uses an MCU microcontroller to precisely control and switch the operating status of each battery cell in the battery pack, improving system flexibility and controllability.

[0038] Specifically, the alarm notification module is timely. When a battery pack anomaly occurs, such as excessively high or low voltage or abnormal internal resistance, the module promptly detects and triggers the alarm mechanism. Remote communication, via GSM and other remote communication methods, sends alarm information to relevant personnel, ensuring they receive and address the anomaly in a timely manner, reducing losses caused by delays.

[0039] See Figure 2 , wherein the data acquisition and transmission module also includes:

[0040] Conversion unit: used to convert analog signals into digital signals through a converter, and transmit voltage, internal resistance, and temperature data through the wireless communication module.

[0041] Among them, the monomer collection unit includes:

[0042] Voltage acquisition subunit: used to connect to the battery through the voltage acquisition line;

[0043] Internal resistance acquisition subunit: used to connect to the battery through the internal resistance test line;

[0048] Among them, also include:

[0049] Alarm notification module: used to send and receive alarm information remotely via GSM.

[0050] Specifically, sensors collect key parameters such as battery pack voltage, internal resistance, and temperature in real time and transmit this data to a remote monitoring center via wireless communication. High-precision sensors and ADC circuits are used to convert analog signals into digital signals, which are then transmitted remotely via wireless communication modules such as Wi-Fi, Zigbee, or 4G / 5G. This ensures real-time and accurate data, providing a foundation for subsequent monitoring, control, and analysis.

[0051] Specifically, the remote monitoring module uses the monitoring center's software platform to remotely monitor and control the battery pack, including viewing real-time data and remotely controlling charging and discharging. Using an MCU as the control core, it receives commands from the remote monitoring center and remotely controls the battery pack through control circuits. This enables remote management and control of the battery pack, enabling online capacity verification, reducing the frequency and cost of on-site maintenance, and improving work efficiency.

[0052] Specifically, to expand applications, high-performance computing units such as DSP digital signal processors or FPGA field programmable gate arrays can be used in combination with algorithm libraries to achieve real-time analysis and processing of data.

[0053] Specifically, the alarm notification module automatically triggers an alarm when a battery pack anomaly or fault occurs, notifying relevant personnel via text message, email, or app push notification. Remote transmission and reception of alarm information is achieved using a GSM / GPRS module or IoT cloud platform. This ensures that operations and maintenance personnel are promptly informed of battery pack anomalies, enabling rapid response and resolution, minimizing the impact of faults on the power generation-side battery booster station.

[0054] This system provides a complete battery pack monitoring system, including data acquisition and transmission, remote monitoring and control, and alarm and notification capabilities. Sensors installed on the battery pack collect key data such as battery voltage, internal resistance, and temperature in real time and transmit it to a remote monitoring center via wireless communication. The remote monitoring center can view the battery pack's operating data in real time and remotely control charging and discharging, enabling comprehensive monitoring and management of the battery pack. This transforms the on-site operation and maintenance model for battery packs in power generation-side booster station scenarios, enabling online capacity verification, remote monitoring of the battery pack, and improved work efficiency.

[0055] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
