[0019] The present application will now be described in conjunction with a preferred embodiment. Figure 1 is a schematic diagram of a cell data processing device provided according to an embodiment of the present application. As shown in Figure 1, the cell data processing device includes a battery module 10, a data acquisition module 20, a data receiving module 30, and a battery management module 40.

[0020] Battery module 10 includes multiple battery cells 100;

[0021] The data acquisition module 20 is deployed on multiple battery cells 100 and is used to transmit the parameter data of each battery cell 100 to the data receiving module 30 wirelessly.

[0022] The data receiving module 30 is wirelessly connected to the data acquisition module 20 and is used to transmit the parameter data transmitted by the data acquisition module 20 to the battery management module 40.

[0024] In some embodiments, as shown in FIG1, the battery cell data processing device provided in this application embodiment includes at least: a battery module 10, a data acquisition module 20, a data receiving module 30, and a battery management module 40. The aforementioned battery module 10 may include multiple battery cells 100. The aforementioned data acquisition module 20 can be used to collect parameter data of each battery cell 100. The parameter data of the battery cell 100 may include key parameters related to the safe operation of the battery, such as the cell pack temperature, battery module temperature, voltage, and internal air pressure of each battery cell 100. The aforementioned data acquisition module 20 may be composed of sensors capable of collecting parameter data of the battery cells 100.

[0025] The aforementioned data acquisition module 20 and data receiving module 30 are wirelessly connected. The data acquisition module 20 and data receiving module 30 can transmit the parameter data of the battery cell 100 wirelessly, avoiding the high maintenance cost of deploying multiple wire harnesses for wired data transmission in related technologies.

The battery module 10, data acquisition module 20, and data receiver 30 can be deployed inside the battery pack to realize wireless transmission of parameter data within the battery pack and improve battery safety.

[0029] In some embodiments, the cell data processing device provided in this application includes a wireless transmission method including Bluetooth communication. The data transmitter 202 is also used to convert parameter data into Bluetooth signals and transmit the Bluetooth signals to the data receiver 30 using Bluetooth communication.

[0030] In an optional embodiment, the data transmitter 202 can convert the parameter data collected by the sensor 201 from analog signals into digital signals, and then into Bluetooth signals that conform to the Bluetooth communication protocol. The Bluetooth signals are then wirelessly transmitted to the data receiver 30 via Bluetooth communication, thereby achieving the purpose of wirelessly transmitting the parameter data of the battery cell 100.

[0031] For example, the data transmitter 202 converts the collected parameter data into multiple response signals, such as multiple temperature and voltage acquisition signals. Data transmission via Bluetooth technology enables real-time data acquisition, improving data acquisition efficiency by 30% and significantly reducing data processing latency and error rates.

For example, it can analyze whether the parameter is greater than a preset threshold, thereby achieving the technical effect of monitoring the operating status of the battery cell 100.

[0037] For example, the battery management module can analyze, process, and store the collected parameter data to monitor the battery status in real time and ensure that the battery operates within a safe range.

The cloud platform 50 can communicate with the battery management module 40 via Ethernet to receive parameter data and analysis results generated by the battery management module 40, so as to achieve centralized management and analysis of the parameter data of the battery cell 100.

[0042] For example, the cloud platform 50 can communicate with the battery management module 40 via Ethernet to obtain parameter data for all battery cells. Based on this, the cloud platform 50 can centrally manage and analyze the parameter data. When the parameter data of a battery cell 100 is detected to be below the consistency threshold, the cloud platform can issue an alarm in a timely manner, effectively ensuring battery safety. The introduction of the cloud platform effectively alleviates the insufficient computing power of the BMS module, significantly improving the timeliness of individual cell health status analysis. Furthermore, this solution employs a dual system of cloud platform and local storage (battery management module 40) to ensure data security and stability, facilitating efficient data analysis.
