[0019] Lightweight battery boxes are often used in various types of bicycles to provide range extension and riding assistance. Lightweight battery boxes are often mounted on the bicycle's diagonal bars or seat posts. In order to reduce weight, they often do not have a thick protective fixing structure. Therefore, lightweight battery boxes have different testing requirements compared to conventional marked battery boxes. How to conduct efficient and comprehensive testing of lightweight battery boxes is a problem to be solved.

[0020] The present application embodiment discloses a lightweight battery box testing method. Figure 1 , a lightweight battery box testing method, comprising the following steps: S1. Generate test requirement instructions: Obtain the battery box test requirements to generate test requirement instructions, wherein the test requirement instructions include one or more of appearance dimension detection requirements, conventional function test requirements, special function test requirements, air tightness test requirements, mechanical safety test requirements, and electrical safety test requirements; S2. Generate a target test plan: obtain the equipment information of the enterprise test equipment group, and generate a target test plan based on the test requirement information and the equipment information by matching a preset test plan model, wherein the target test plan includes at least one test device, at least one test process information, and equipment parameter information; wherein the test plan model is a machine learning model obtained by iterative training of historical data, and the specific training steps of the machine learning model are prior art and will not be described in detail here; S3. Parameter setting: Generate a scheduling instruction according to the target test plan, transport the battery box to be tested to the designated test equipment, and send equipment parameter information to the test equipment for parameter setting; S4. Test the battery box: Generate control instructions based on the target test plan according to the test process information, and control the test equipment to test the battery box according to the test process. Through the above steps, a test plan model is established. According to the actual test requirements of the lightweight battery box to be tested, combined with the actual situation of the company's test equipment group, a customized target test plan is generated, and the test equipment group is controlled to perform efficient and comprehensive testing of the lightweight battery box according to the user's test requirements, so as to effectively improve the test accuracy and test efficiency of the lightweight battery box.

The battery box of a traditional electric vehicle is often inserted into the body of an electric bicycle, and is fixed and limited by the body armor. The application scenarios are mostly urban roads. Lightweight battery boxes are often used in various types of pedal bicycles, among which mountain bikes account for the highest proportion. Their driving scenarios are also mostly outdoor roads. During the riding process, it is inevitable that there will be splashing of ground gravel. The lightweight battery box does not have thick armor due to its lightweight requirements. Therefore, compared with the traditional battery box test equipment, the test equipment group of this application is also aimed at setting up splash test equipment to simulate the outdoor gravel splashing scenario, which can more comprehensively and efficiently detect the lightweight battery box.

The two sets of linear guides 13 are fixedly arranged on the inner wall of the test chamber 11 in the vertical direction, and are arranged opposite to each other. Multi-axis pan-tilt platforms 14 are installed on the sliders of the two sets of linear guides 13. The two pneumatic steel ball launchers 15 are respectively fixedly arranged at the output ends of the two multi-axis pan-tilt platforms 14. Through the setting of the splash test equipment 1, when conducting a splash test, the two sets of linear guides 13 and the multi-axis gimbal 14 can be controlled to cooperate with each other according to the control instructions of the target test plan, and beads of various specifications can be launched from various angles at specified different initial velocities, and splashed on the battery box 3 to be tested, thereby simulating the scenario of the lightweight battery box 3 encountering splashing of road gravel in the wild, and more comprehensively testing the safety performance of the battery box 3, thereby effectively improving the test accuracy and test efficiency of the lightweight battery box 3.

Two adjacent columns 171 are commonly connected to the fixed energy-absorbing net 173, and two adjacent lifting columns 172 are commonly connected to the lifting energy-absorbing net 174. Both ends of the lifting energy absorption net 174 in the width direction are provided with multiple lifting slip rings 176, and multiple lifting slip rings 176 are sleeved on the lifting column 172. The four lifting columns 172 are all equipped with electric pulley groups 177 for driving the lifting energy absorption net 174 to lift and lower. Through the setting of the energy absorption component 17, after any pneumatic steel ball launcher 15 is driven to the specified position and adjusted in place by the linear guide 13 and the multi-axis pan-tilt head 14, the electric pulley group 177 on the opposite side is controlled to drive the lifting energy absorption net 174 to rise, and ensure that the lifting energy absorption net 174 in its direction is lowered, and then the pneumatic steel ball launcher 15 is controlled to launch the beads to hit the battery box 3 to perform a splash test. And through the setting of the energy absorption elastic pad 16 and the new energy component, the beads that rebound after hitting the battery box 3 during the splash test can be energy-limited to avoid cyclic splashing and affecting the test accuracy. At the same time, the opposite pneumatic steel ball launcher 15 can be protected to improve the service life of the equipment.

[0024] Reference Figure 5 The method of generating control instructions based on the target test scheme according to the test process information and controlling the splash test device 1 to test the battery box 3 specifically includes the following steps: A1. Installing the battery box 3: Select the connector 121 corresponding to the battery box 3 to be tested, and install the battery box 3 on the test base 12; A2. Launch adjustment: Generate control instructions based on the target test plan and test process information, control the linear guide 13 and the multi-axis pan / tilt 14 to drive the specified pneumatic steel ball launcher 15 to move to the specified position according to the test process and adjust the launch angle of the pneumatic steel ball launcher 15; A3.

Through the above steps, according to the control instructions of the target test scheme, the two sets of linear guides 13 and the multi-axis gimbal 14 can be controlled to cooperate with each other, and various specifications of beads can be launched from various angles at specified different initial velocities to splash on the battery box 3 to be tested, thereby simulating the lightweight battery box 3 encountering the road gravel splashing in the wild, and more comprehensively testing the safety performance of the battery box 3, so as to effectively improve the test accuracy and test efficiency of the lightweight battery box 3.

[0025] Reference Figure 6 The thermal simulation test equipment 2 includes a sealed chamber 21, a thermal simulation verification component 22, an environmental adjustment component 23, a plurality of shell temperature sensor contacts 24 for collecting battery box shell temperature information, a plurality of battery temperature sensor contacts 25 for inserting into the battery box 3 to collect battery temperature information, and a plurality of box body temperature sensor contacts 26 for inserting into the battery box 3 to collect box body internal environmental temperature information. The sealed chamber 21 is hinged with a heat preservation chamber cover 211, and the thermal simulation verification component 22 is installed in the sealed chamber 21 to verify the thermal simulation results. The specific structure is the prior art and will not be repeated here. The environmental adjustment component 23 is installed in the sealed chamber 21 to adjust the environmental temperature and humidity in the sealed chamber 21. The specific structure is the prior art and will not be repeated here. Compared with conventional battery boxes, the lightweight battery box 3 is easily accessible to riders due to its installation position and lacks external heat insulation. Therefore, when conducting thermal simulation tests, it is necessary not only to conduct verification experiments based on the thermal simulation data generated by the previous simulation program, but also to collect the temperature performance of the battery box 3 shell when the battery is in high-intensity use and when the battery temperature is highest, so as to ensure the user's riding experience and riding safety.

[0026] In addition, the sealed chamber 21 is connected with an air supply pipe 212 and an air outlet pipe 213 which are arranged opposite to each other, and are used to deliver a unidirectional airflow of a specified temperature into the sealed chamber 21. By setting the air supply pipe 212 and the air outlet pipe 213, the wind conditions of the bicycle at different speeds can be simulated during the thermal simulation verification, and the heat dissipation performance of the battery box 3 with the circulating air duct heat dissipation mechanism can be more fully utilized, which helps to improve the accuracy of the test data.

[0027] Reference Figure 7 The above-mentioned control instructions are generated according to the test process information based on the target test scheme, and the thermal simulation test equipment is controlled to test the battery box, which specifically includes the following steps: B1. Determine the test points of the shell: Model the battery box 3 to generate a battery box model, and use a preset riding analysis model to analyze the high-frequency contact area between the user and the battery box 3 to be tested to determine the test points.

Collect the battery temperature information and battery box shell temperature information during the normal test, extract the battery box shell temperature when the battery temperature is at the highest value, and determine whether it exceeds the preset contact safety threshold; it should be noted that the ambient temperature range of the normal test is preset by the management personnel; B5. Generate experience risk warning: If exceeded, generate experience risk warning and add it to the test report and send it to the management staff. Through the above steps, during the thermal simulation verification process, by collecting the battery temperature and shell temperature under normal temperature environment during the test, the heat dissipation and heat insulation performance of the battery box can be judged, and the temperature performance of the battery box shell under the highest battery temperature can be determined to ensure the user's riding experience and riding safety.

[0028] The above-mentioned acquisition of the battery temperature information and the battery box 3 shell temperature information during the test under the normal test also includes: extracting the maximum value of the battery box shell temperature, verifying whether the corresponding battery temperature at this time is the maximum value of the battery temperature, and if not, generating an aging risk prompt to be added to the test report and sent to the management personnel, so as to further ensure that the battery box 3 can bring a good user experience to the user during the user's use.

[0029] Reference Figure 8 , obtain the equipment information of the enterprise test equipment group, and generate the target test plan based on the test requirement information and equipment information through the preset test plan model matching, which specifically includes the following steps: C1. Obtaining device information: Obtaining device information of each test device in the enterprise's test device group, the device information includes device identification information, device performance parameter information, device usage information and device floppy drive information; C2. Generate test sub-schemes: Generate test sub-schemes corresponding to each requirement in the test requirement information through matching of a preset test scheme model based on the test requirement information and the equipment information. The test sub-schemes include at least one test equipment, test sub-process information, and equipment parameter information; C3. Scheme classification: Classify the test sub-schemes of each requirement to generate non-destructive test sets and destructive test sets; C4. Integrate and generate target test plans: Sort the time consumption of each test sub-plan in the non-destructive test set and the destructive test set from short to long based on the test sub-process information, and sort and integrate each test sub-plan in the non-destructive test set and each test sub-plan in the destructive test set according to the sorting results to generate the target test plan. By classifying and sorting the test sub-plans for each test requirement, the use of test consumables can be reduced and the test cost can be saved. At the same time, when there are many test items, the test sub-plans that consume time are given priority, which can more efficiently screen out unqualified battery boxes and save test resources.
