[0085] Figure 3 A flowchart of a method for intelligent power distribution testing of a controller provided in an embodiment of the present disclosure.

[0086] like Figure 3 As shown, the method comprises the following steps:

[0087] Step 201, loading the test case corresponding to the intelligent power distribution channel in the controller.

[0088] Smart power distribution is the intelligent distribution of load power according to load requirements or power status. It can also realize data monitoring and diagnosis of load power distribution. It is usually implemented by electronic fuse (Efuse) chip or discrete sampling circuit + field effect transistor (MOSFET).

[0089] In the embodiments of the present disclosure, the intelligent power distribution channel is a circuit in the controller that implements intelligent power distribution, for example, it can be a combination of a discrete sampling circuit and a MOSFET; the present disclosure is not limited to this. Different test cases are generated according to the differences in the intelligent power distribution channels in different controllers.

[0090] Step 202: Setting the operating voltage of the controller based on the voltage mode in the test case.

[0091] In the embodiments of the present disclosure, if the power supply is unstable, the controller cannot operate at the rated voltage. Therefore, by testing the operating conditions of the controller under different voltage modes, the operating data of the controller under extreme working conditions can be obtained. The controller can be optimized and designed based on the data obtained from the test. After loading the test case, the operating voltage of the controller needs to be set first to measure the measurement data of the controller under different voltage modes.

[0092] Step 203 , testing the intelligent power distribution channel based on the test sub-cases in the test case under different voltage modes of the controller, respectively, where different test sub-cases correspond to different working conditions of the intelligent power distribution channel.

[0093] In the embodiments of the present disclosure, after setting the working voltage according to the voltage mode, the test of the intelligent power distribution channel under different working conditions is implemented according to the test sub-cases in the test case; the test under different working conditions can be a simulation test under normal working conditions of the load of the intelligent power distribution channel, such as: a test under rated current; or a fault simulation test of the intelligent power distribution channel, such as: a short circuit to ground test, etc. It should be noted that the present disclosure does not limit the test sub-cases.

[0094] The present disclosure provides a method for testing the intelligent power distribution of a controller, which includes loading a test case corresponding to an intelligent power distribution channel in the controller; setting the operating voltage of the controller based on the voltage mode in the test case; and testing the intelligent power distribution channel based on the test sub-cases in the test case under different voltage modes of the controller, wherein different test sub-cases correspond to different working conditions under the intelligent power distribution channel. Compared with the related art, the embodiment of the present disclosure realizes automatic testing of the intelligent power distribution channel under different working conditions by configuring the test configurations of the intelligent power distribution channel under different working conditions as test cases. It is possible to achieve the unification of test standards, thereby improving the accuracy of the test.

[0095] In order to clearly illustrate the embodiments of the present disclosure, the embodiments of the present disclosure provide a flowchart of another method for testing intelligent power distribution of a controller.

[0096] like Figure 4 As shown, the method comprises the following steps:

[0097] Step 301: Generate the test case based on the load characteristics in the intelligent power distribution channel.

[0098] Specifically, in the embodiments of the present disclosure, the load characteristics are characteristics of some circuits of the load corresponding to the intelligent distribution channel, such as volt-ampere characteristics, changes in current in the circuit, etc. Different intelligent distribution channels can be composed of different circuits or devices; for example, it can be an electronic fuse (Efuse) chip, or it can be a discrete sampling circuit + field effect transistor (MOSFET). There will also be differences in the loads corresponding to different intelligent distribution channels. Therefore, it is necessary to generate test cases for different intelligent distribution channels based on the load characteristics.

[0099] Step 302: Load the test case corresponding to the intelligent power distribution channel in the controller.

[0100] Step 303: Based on the voltage mode in the test case, respectively set the operating voltage of the controller corresponding to the voltage mode, wherein the voltage mode includes at least one of a rated voltage mode, an overvoltage mode and an undervoltage mode.

[0101] Specifically in the embodiments of the present disclosure, please refer to Figure 5 , load the test case through the test host, and set the operating voltage of the controller according to the voltage mode set in the test case. When generating test cases, you can select the voltage mode to be tested from the rated voltage mode, overvoltage mode and undervoltage mode according to different test purposes, and generate corresponding test cases. The above three voltage modes cover the full operating voltage range of the controller, and can realize the full voltage range test of the controller's intelligent power distribution channel. Provide test data support for optimizing the design of the controller.

[0102] Step 304: Control the controller to operate.

[0103] Step 305, testing the intelligent power distribution channel based on the test sub-cases in the test case, wherein the test sub-cases include at least one of a rated current test, a peak current test, a short-time thermal shock test, an overcurrent protection test, a short-circuit protection test, and a fault diagnosis test.

[0104] For details in the disclosed embodiments, please continue to refer to Figure 5When the controller is working, the rated current test, peak current test, short-time thermal shock test, overcurrent protection test, short-circuit protection test and fault diagnosis test of the controller's intelligent power distribution channel are implemented. Rated current test, test whether the current recovery accuracy meets the requirements. Peak current test, test whether the current acquisition accuracy and peak current duration meet the requirements. Short-time thermal shock test (I2t protection test), test whether the I2t protection curve meets the requirements. Overcurrent protection test, test whether the overcurrent protection function meets the requirements. Short-circuit protection test, test whether the short-circuit protection function meets the design requirements. Fault diagnosis test, simulate load open circuit, short circuit to ground, short circuit to power supply in turn, test whether the diagnostic function meets the design requirements.

[0105] Step 306: Control the controller to sleep.

[0106] Step 307: Test the intelligent power distribution channel based on the test sub-case in the test case, wherein the test sub-case also includes at least one of a bypass function test and a reverse wake-up test.

[0107] For details in the disclosed embodiments, please continue to refer to Figure 5 , by enabling the controller to enter the sleep state, complete the bypass function test and reverse wake-up test of the controller. Bypass function test (Bypass current test), test whether the bypass current meets the requirements. Reverse wake-up function test, test whether the reverse wake-up function of the intelligent power distribution meets the requirements.

[0108] It should be noted that the embodiment of the present disclosure does not limit the controller to be tested in sleep state first or tested in sleep state later. Therefore, there is no necessary sequence between steps 304-305 and steps 306-307.

[0109] Step 308, determining whether the controller is tested in the current voltage mode.

[0110] Step 309 : When the controller completes the test in the current voltage mode, switch to a different voltage mode and set the corresponding operating voltage.

[0111] Step 310: Based on the reset working voltage, the intelligent power distribution channel is tested according to the test sub-cases in the test case until the test is completed in all voltage modes.

[0112] For details in the disclosed embodiments, please continue to refer to Figure 5After the test is completed in the current voltage mode of the controller, a different voltage mode is switched for testing. Exemplarily, after the controller completes all the tests of steps 304 to 307 in the rated voltage mode, it switches to the overvoltage mode and sets the corresponding working voltage; continues to perform all the tests of steps 304 to 307; until all the tests of steps 304 to 307 are completed in all voltage modes. After all the tests are completed, a test report is generated.

[0113] It should be noted that the embodiments of the present disclosure may include multiple steps. For the convenience of description, these steps are numbered, but these numbers do not limit the execution time slots or execution order between the steps; these steps can be implemented in any order, and the embodiments of the present disclosure do not limit this.
