[0083] Embodiment 2

[0084] Battery sensors are commonly used in the automotive industry to collect data from batteries that realize the power supply function in the battery. In the field of testing battery sensors for automobiles, real vehicles are often used for calibration and testing. The above-mentioned real vehicle testing method requires frequent power outages to ensure the safety of the test. Due to its working characteristics, the battery sensor uses a real-time integration algorithm for data feedback. Once the initialization data is lost due to an unexpected power outage, the learning time will take several hours to complete after the power is turned on again. As a result, the real vehicle testing method causes the battery sensor to need to be constantly relearned during the test, which not only has low test efficiency, but also affects the data collection accuracy. When it is necessary to verify the function of the sensor to collect specific battery capacity and temperature, the test using a real vehicle is inefficient and cannot be carried out efficiently.

[0085] In order to solve the above technical problems, a functional logic test device for a battery sensor is provided in this embodiment. The functional logic test device performs testing by directly connecting to a test battery sensor, thereby avoiding technical problems caused by real vehicle testing.

[0086] In certain implementations of this embodiment, the functional logic test device includes a DC regulated power supply, a power-consuming load, a battery, a vehicle controller, and a test host computer. The DC regulated power supply and the power-consuming load are respectively connected to the battery to adjust the state of charge of the battery to a preset state of charge; further, the DC regulated power supply and the power-consuming load are respectively connected to the test host computer signal to receive the charge adjustment command sent by the test host computer to obtain the preset state of charge from the charge adjustment command. The output end of the battery is connected to the input end of the test battery sensor so that the test battery sensor can collect data.

[0087] Furthermore, the vehicle-mounted controller is signal-connected to the test host computer to obtain the test signal sent by the test host computer according to the test content and the detection data sent by the test battery sensor, and processes the detection data according to the test signal to generate a processing result, and sends the processing result to the test host computer; wherein the output end of the test battery sensor is connected to the input end of the vehicle-mounted controller.

[0088] Furthermore, the test host computer is connected to the test battery sensor signal to control the test battery sensor to collect data from the battery, and obtain the detection data and the processing results sent by the test battery sensor to generate the test results of the test battery sensor based on the detection data and the processing results.

[0089] In some implementations of this embodiment, taking a vehicle-mounted battery sensor as an example, the functional logic test device provided in this embodiment is used to test the battery sensor. The connection circuit diagram between the functional logic test device and the battery sensor is as follows: Figure 3 shown.

[0090] Specifically, refer to Figure 3 The functional logic test device includes a DC regulated power supply 301, a power consumption load 302, a battery 303, a vehicle controller 304 and a test host computer 305. The output end of the battery 303 is connected to the input end of the battery sensor 306, and the output end of the battery sensor 306 is connected to the input end of the vehicle controller 304 and the input end of the test host computer 305 respectively.

[0091] Further, refer to Figure 3 In order to ensure that the battery sensor 306 does not lose the module initialization setting due to an accidental power outage when the battery 303 operates at a normal voltage, in this embodiment, the B+, i.e., the power line, of the battery sensor 306 is fixed to the positive pole of the battery 303.

[0092] Furthermore, if Figure 3 As shown, the power-consuming load 302 and the DC regulated power supply 301 are connected in series to the circuit of the battery 303. In the specific test content, in order to simulate different charge states corresponding to the battery, the power-consuming load 302 and the DC regulated power supply 301 receive commands sent by the test host computer 305 to determine whether the battery 302 needs to consume power or increase power.

[0093] Specifically, when the power of the storage battery 303 needs to be consumed, the DC regulated power supply 301 does not work, and the storage battery 303 is controlled to discharge by adjusting the power consumption load 302; on the contrary, when the storage battery 303 needs to be charged, the DC regulated power supply 301 provides a stable voltage output, and the charging current can also be adjusted by the power consumption load 302. Preferably, the power consumption load 302 can adopt an adjustable electronic load device to realize the adjustment of the charging current or the power consumption of the storage battery 303.

[0094] Reference Figure 3 After adjusting the power status of the battery 303, in actual application, the data collected by the battery sensor 306 will be sent to its superior part, namely the vehicle controller 304. In order to verify whether the functional logic of the battery sensor 306 meets the design requirements, it is necessary to monitor the data generated by the vehicle controller 304 after receiving the detection data sent by the battery sensor 306.

[0095] Specifically, in some implementations of this embodiment, in order to enable the test host computer 305 to receive the detection data sent by the battery sensor 306 and the processing result sent by the vehicle controller 304, so as to generate a test result including whether the battery sensor 306 functions normally or abnormally. Preferably, a CAN and LIN acquisition control tool can be installed in the test host computer 305 to collect data through the CAN and LIN acquisition control tool.

[0096] Furthermore, after the CAN and LIN acquisition control tools are set, in order to realize the two-way information interaction between the test host computer 305 and the battery sensor 306 and the two-way information interaction between the test host computer 305 and the vehicle controller 304. In some implementations of this embodiment, the LIN line of the test host computer 305 is partially connected to the LIN line of the battery sensor 306, and the CAN line of the test host computer 305 is partially connected to the CAN line of the vehicle controller 304.

[0097] According to the LIN line part, the test host computer 305 not only receives the detection data sent by the battery sensor 306, but also sends or modifies specific analog signals to the battery sensor 306, thereby changing the test parameters to make the test coverage more comprehensive. Simultaneously, according to the CAN line part, the test host computer 305 not only receives the processing results sent by the vehicle controller 304, but also sends or modifies specific analog signals to the vehicle controller 304, thereby changing the test parameters to make the test coverage more comprehensive.

[0098] In using Figure 3 When the functional logic test device shown in the figure performs a functional logic test on a test battery sensor, in order to improve the universal applicability of the functional logic test device to the test environment, the following Figure 3 The functional logic test device shown is arranged on a movable trolley made of aluminum profile, so that the functional logic test device can be easily moved to any test environment through the trolley, such as being moved as a whole to a high and low temperature environment chamber for real temperature testing.

[0099] The functional logic test device provided in this embodiment greatly simplifies the test process by replacing the actual vehicle test method with a bench, and can significantly improve the test and problem-solving efficiency during the parts development and verification stage. Furthermore, the platform of the test device can be compatible with different battery sizes, and different battery models and battery sensors can be replaced for testing, which not only simplifies the test method of the battery sensor, but also improves the test efficiency.
