Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicles, and in particular to a wireless battery module detection system and method. Background Art

[0002] Battery electric vehicles (BEVs) are vehicles that use an onboard power source to propel their wheels, using an electric motor and complying with all road traffic and safety regulations. Their environmental impact is relatively low compared to traditional vehicles, and their prospects are widely optimistic. With the development of electric vehicles, the demand for testing battery modules used in electric vehicles is also increasing.

[0003] The traditional method for testing battery modules involves connecting them via wiring harnesses and connectors, which are then placed on conveyor belts for transport. However, this method can be prone to damage, potentially leading to safety issues. Therefore, wireless battery module testing is a future trend.

[0004] However, wireless battery module testing requires prior networking of the wireless battery module with a wireless communication box, a process that takes a long time. Traditionally, wireless battery modules are placed on assembly line conveying equipment and wait for networking and testing to be completed before they are moved on. This wastes a lot of time and makes wireless battery module testing inefficient.

[0005] Therefore, how to provide a wireless battery module detection system and method to improve the efficiency of wireless battery module detection has become an urgent problem to be solved. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a wireless battery module detection system and method to improve the efficiency of wireless battery module detection.

[0025] Furthermore, the wireless communication box further includes:

[0026] A second power supply module is connected to the 2.4G wireless module and the second SPI to isoSPI chip respectively.

[0027] In a second aspect, the present invention provides a wireless battery module detection method, comprising the following steps:

[0028] Step S10: The computer writes the MAC address of the wireless battery module into the wireless communication box via the isoSPI communication box;

[0029] Step S20: The wireless battery module is transported to the first workstation by the first assembly line conveying equipment, the wireless communication box is disconnected from the isoSPI communication box, and the wireless communication box is placed on the upper end of the wireless battery module;

[0030] Step S30: During the process of transporting the wireless battery module and the wireless communication box to the second workstation via the first assembly line conveying device, the wireless communication box completes networking with the wireless battery module based on the MAC address;

[0031] Step S40: At the second workstation, the wireless communication box is connected to the isoSPI communication box, and the computer sequentially detects the wireless battery module through the isoSPI communication box and the wireless communication box;

[0032] Step S50: disconnect the wireless communication box from the isoSPI communication box, and transfer the wireless communication box to the first station through the second assembly line conveying equipment for recycling.

[0033] Furthermore, in step S40, the computer sequentially detects the wireless battery module through the isoSPI communication box and the wireless communication box as follows:

[0034] The computer presets a voltage standard value, a temperature standard value, and an error range, and the computer sequentially obtains the actual voltage value and actual temperature value of the wireless battery module through the isoSPI communication box and the wireless communication box;

[0035] The computer determines whether the deviation between the voltage standard value and the actual voltage value is less than the error range, and if so, generates a voltage qualified test result; if not, generates a voltage unqualified test result;

[0036] The computer determines whether the deviation between the temperature standard value and the actual temperature value is less than the error range. If so, a test result indicating that the temperature is qualified is generated; if not, a test result indicating that the temperature is unqualified is generated.

[0037] The advantages of the present invention are:

[0038] By setting up a first assembly line conveying device and a second assembly line conveying device, when the wireless battery module is transferred to the first workstation through the first assembly line conveying device, the wireless communication box with the MAC address of the wireless battery module written therein is placed on the wireless battery module, and the wireless communication box is transferred to the second workstation along with the wireless battery module by the first assembly line conveying device.

After the detection is completed, the wireless communication box can be transferred back to the first workstation through the second assembly line conveying device for recycling, that is, a reasonable time allocation is made for networking and detection, thereby greatly improving the efficiency of wireless battery module detection.
