Furthermore, this significantly occupies the interior space of new energy vehicles. In the foreseeable future, the number of sensors will increase dramatically as the number of batteries increases, and the equipment used to transmit these various sensor data will occupy an increasingly larger area.

[0016] Figure 1 The figure is a schematic structural diagram of a battery detection device for new energy vehicles according to an embodiment of the present utility model.

[0017] Reference Figure 1 According to an embodiment of the present invention, a battery testing device for a new energy vehicle comprises: multiple acquisition boards 1, multiple sets of monitoring components 2, a mainboard 3, and a server 4. Each acquisition board 1 is connected to multiple sets of monitoring components 2, and each set of monitoring components 2 is fixed to the surface of a battery pack 5 within the new energy vehicle, thereby collecting operating data from each battery pack 5 within the new energy vehicle. One side of the mainboard 3 is electrically connected to a structure formed by cascading multiple acquisition boards 1, and the other side of the mainboard 3 is electrically connected to the server 4. The mainboard 3 receives data transmitted by each acquisition board 1 and uploads it to the server 4.

[0018] Figure 2 The figure is a schematic structural diagram of a collection board according to an embodiment of the present utility model.

[0019] Reference Figure 2 , wherein each acquisition board 1 includes two data transmission interfaces 11, at least one data receiving port 12, a first power module 13, a first communication module 14 and a first single-chip microcomputer 15. Each data transmission interface 11 is arranged relatively to each other and is located on the end surface of the dielectric substrate of the acquisition board 1 on the opposite side. Among them, each data transmission interface 11 is connected through the first communication module 14, and the adjacent acquisition boards 1 are connected to the corresponding data transmission interfaces 12 through a shielded cable, thereby being cascaded into one. The first power module 13 is connected to the first single-chip microcomputer 15 and each data transmission interface 11 to maintain the stable operation of the first single-chip microcomputer 15 and each data transmission interface 11. The first single-chip microcomputer 15 is connected to each data receiving port 12 respectively to collect and store the operating data information of the corresponding battery pack 5.

[0020] Specifically, each monitoring assembly 2 includes multiple temperature and humidity sensors 21, multiple pressure sensors 22, and multiple gas sensors 23. Each data receiving port 12 is connected to one of the temperature and humidity sensors 21, pressure sensors 22, and gas sensors 23. The number of each sensor is set according to the monitoring requirements of the battery pack 5.

[0021] Furthermore, in order to optimize the wiring layout on the surface of the acquisition board 1 and further reduce the volume of the entire acquisition board 1, in this embodiment, each acquisition board 1 also includes a data transfer interface 16. One end of the data transfer interface 16 is connected to each data receiving port 12, and the other end of the data transfer interface 16 is connected to the first single-chip microcomputer 15. During the data acquisition process for each battery pack 5, each data receiving port 12 transmits corresponding data information to the first single-chip microcomputer 15 at intervals. The data transfer interface 16 compiles each set of data and stores it in the first single-chip microcomputer 15. Upon receiving the upload command issued by the mainboard 3, the first single-chip microcomputer 15 in each acquisition board 1 calls the internally stored operating data information of the battery pack 5 and transmits the data to the next acquisition board 1 closer to the mainboard 3 through the data transmission interface 11 until the mainboard 3 inputs the data into the mainboard 3. Each acquisition board 1 transmits data streams through its own data transmission interface 11, and in order to further save the volume of each acquisition board 1, each acquisition board 1 only transmits data sent from the adjacent acquisition board 1 and does not store the data, thereby saving data storage space of each acquisition board 1.

[0022] Figure 3 The figure is a structural diagram of a mainboard according to an embodiment of the present utility model.

[0023] Reference Figure 3 Specifically, the mainboard 3 includes a second single-chip microcomputer 31, a wireless module 32, a second power module 33, a second communication module 34, and a data acquisition port 35. The output of the second single-chip microcomputer 31 uploads the operating data of each battery pack 5 to the server 4 via the wireless module 32. The input of the second single-chip microcomputer 31 is connected to the data acquisition port 35 via the second communication module 34. The second power module 33 is connected to the power supply of the second single-chip microcomputer 31 to drive its operation. The data acquisition port 35 is connected to one of the data transmission interfaces 11 on the acquisition board 1 via a shielded cable.

[0024] The first power module 13 and the second power module 33 each include corresponding power supply circuits compatible with the operation of each microcontroller, as well as protection circuits for stabilizing the output voltage or current. The wireless module integrates commonly used wireless communication modules, such as WiFi (wireless network), Zigbee (a low-speed, short-range wireless network protocol), LoRa (long-range radio) mok, 2G-5G communication modules, and Bluetooth. Preferably, to facilitate adjustment of the data upload frequency of each acquisition board 1, each acquisition board 1 is provided with an external debugging interface 6 connected to the first microcontroller 15, and the mainboard 3 is provided with a debugging interface 36 connected to the second microcontroller 33.

[0025] When the number of battery packs 5 in the new energy vehicle increases, the acquisition boards 1 are cascaded to quickly match the monitoring solution for the previously deployed battery packs 5, thereby completing the construction of the monitoring system for the new battery pack 5 deployment solution.

[0026] In summary, the utility model collects the operating data of each battery pack in a new energy vehicle through a structure formed by cascading multiple acquisition boards. It has high scalability and space compression efficiency. When the number of deployed battery packs increases, it only needs to increase the number of cascaded acquisition boards to complete the corresponding deployment.
