Detailed Description
The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.
Example 1
Referring to fig. 1, the present embodiment provides a charging test method, which specifically includes the following steps:
and S100, the test system sends a test instruction to the charging product to be tested. Specifically, the upper computer in the test system may send the test instruction to the charging product to be tested, and when the upper computer does not exist in the test system, the test instruction may also be directly stored or cured in a certain component in the test system, and during the test, the test instruction is directly sent to the charging product to be tested.
And S200, the charging product to be tested runs the test instruction, and the test state of the charging product to be tested is set by running the test instruction. Specifically, the test state comprises a first test state and/or a second test state; the first test state is that the detection function of the type of the power supply equipment is closed; the second test state is the detection function of closing to ambient temperature, and through adjusting the test state to the first test state and/or the second test state, the influence of the charging product to be tested on the type of the power supply equipment, the ambient temperature and the like can be effectively prevented from causing inaccurate test.
S300, the charging product to be tested carries out charging test according to the test strategy in the test instruction; the test strategy comprises the following steps: and sequentially acquiring a plurality of signals for simulating the type of the charging equipment and/or sequentially acquiring a plurality of signals for simulating the ambient temperature, and respectively performing charging tests according to the signals for simulating the type of the charging equipment and/or the signals for simulating the ambient temperature, namely simulating the signals of the type of the charging equipment and/or the signals of the ambient temperature by using the signals in the test instruction. The test strategy comprises the following steps: the value of the power supply device type register and/or the ambient temperature register is modified in accordance with the signal for simulating the charging device type and/or the signal for simulating the ambient temperature. In detail, the test status is divided into the following five cases according to the different test contents:
in the first case, only the charging situations of different power supply device types are tested. Under the condition, the detection function of the charging product to be detected on the type of the power supply equipment is closed, and at the moment, the detection function on the environment temperature is opened; then obtaining a plurality of signals for simulating the type of the charging equipment from the test instruction, modifying the value of a power supply equipment type register according to the plurality of signals for simulating the type of the charging equipment, then respectively carrying out charging test, and recording test data of each test node; through the mode, the charging conditions of different power supply equipment types can be simulated, and the charging regulation capacity of the intelligent charging equipment can be intuitively reflected. Under the condition, the intelligent charging equipment is divided according to different power supply equipment types and comprises a plurality of charging states, each charging state corresponds to one power supply equipment type, and for the example of charging a computer USB port, a common charger and a quick charger aiming at the power supply type, each charging type corresponds to one charging state; the state of charge in this example can be divided into three gears, depending on the type of charge: for example, the value of the power supply device type register is set to a first value, such as 0, and at this time, corresponds to a first charging current gear, such as a 500mA charging gear; setting the value of the power supply equipment type register as a second numerical value, such as 1, at the moment, corresponding to a second charging current gear, such as a 2A charging gear; the value of the power supply device type register is set to a third value, such as 2, which corresponds to a third charging current step, such as a 3A charging step. Those skilled in the art can understand that the number of the charging states, the setting of the current magnitude, and the setting of the value of the charging current configuration register may be modified accordingly as needed, and the present application does not limit the present application. It should be noted that, the value of the power supply device type register and the corresponding charging gear are set values of the charging product to be tested, that is, in the actual normal charging process, the charging product automatically adjusts the actual charging current to the gear according to the charging gear. In the test, the value of the set power supply equipment type register is an analog value, for example, when the actual charging condition of the computer USB port needs to be detected, the value of the power supply equipment type register is modified to be 0, so that the capability of automatically adjusting the charging current of the charging product to be tested when the power supply equipment type is the computer USB port is tested. Then detecting the actual charging condition of the common charger, and modifying the value of the type register of the power supply equipment into 1; and detecting the actual charging condition of the quick charger, and modifying the value of the power supply equipment type register to be 2. The detection sequence of the computer USB port, the common charger and the quick charger can be set according to the requirement. It can be understood by those skilled in the art that the examples of 500mA, 1A, 2A are merely set charging target values, i.e., ideal charging currents at the time of actual charging. It is not always necessary whether the charging test current in the actual test is within an interval around the value and the value. It should be further noted that the types of power supply devices in the present application are not limited to USB ports of computers, general chargers, and fast chargers; in addition to this, various types of mobile power supplies and the like are also included.
In the second situation, only the charging situations with different environmental temperatures are tested, in this situation, the detection function of the charging product to be tested on the environmental temperatures is closed, and at the moment, the detection function of the charging product to be tested on the type of the power supply equipment is opened; and then acquiring a plurality of signals for simulating the ambient temperature from the test instruction, and modifying the value of the ambient temperature register according to the signals for simulating the ambient temperature. Then, respectively carrying out charging tests, and recording test data of each test node; through this kind of mode, can simulate the condition of charging to different ambient temperature, can directly test out intelligent charging equipment to the regulation ability that charges of different ambient temperature. In this case, the intelligent charging device includes a plurality of charging states for charging conditions of different environmental temperatures according to different temperature values, for example, a series of discrete temperature values (e.g., -5 ℃, 0 ℃, 25 ℃, 60 ℃), and sets a plurality of charging shifts according to different temperature values, and sets corresponding charging currents or maximum charging currents in different charging shifts. Under each charging gear, a corresponding value of the environment temperature register and different values of the environment temperature register are used as the basis for adjusting the actual charging current. During testing, the value of the corresponding environment temperature register is set according to a signal for simulating the environment temperature in the test instruction, and test data are acquired according to the value. Whether the acquired test data meets the requirements is used as a standard for testing whether the charging test for the ambient temperature is qualified. It should be noted that, depending on the environment temperature simulated by the test, there may be a plurality of test nodes in this case, or one test node in this case, but the number of test nodes is the same as the number of values of the corresponding environment temperature register, and after the test data of each charge node is read (native path:/sys/class/power _ supply/battery /) the test data is stored in one file. It will be understood by those skilled in the art that the value of each ambient temperature register may correspond to a range of ambient temperatures, e.g., when the value of the ambient temperature register is set to 0, the meaning indicated may be: the ambient temperature value is less than-5 ℃, so that the adjusting capacity of the charging product to be tested for charging according to the ambient temperature under each ambient temperature condition can be tested by sequentially changing the value of the ambient temperature register, wherein the adjusting capacity refers to the adjusting capacity for the charging current and/or the charging voltage.
In a third case, the power supply device type and the ambient temperature are simulated at the same time to test the charging condition, and in this case, the detection function for the power supply device type and the detection function for the ambient temperature are turned off. Then simultaneously acquiring a plurality of signals for simulating the type of the charging equipment and a plurality of signals for simulating the ambient temperature, and combining the plurality of signals for simulating the type of the charging equipment and the plurality of signals for simulating the ambient temperature, wherein each combination comprises one signal for simulating the type of the charging equipment and one signal for simulating the ambient temperature; for example, a series of discrete temperature values (e.g., -5 ℃, 0 ℃, 25 ℃, 60 ℃) are taken as examples for charging the power supply type of a computer USB port, a common charger, and a quick charger; (computer USB port, -5 ℃) can be used as a combination, and the meaning is as follows: the test conditions are that the type of the power supply equipment is a computer USB port, and the environmental temperature is-5 ℃. Of course, the combination can also be that the computer USB port is respectively combined with other environmental temperature values, and the common charger and the quick charger are respectively combined with each environmental temperature value, and the like. The skilled person will be able to select how and how many such combinations are required, as desired, and will not be exhaustive here. The value of the power supply device type register (corresponding to the power supply device type in the combination) and the value of the ambient temperature register (corresponding to the ambient temperature in the combination) are modified in sequence according to the respective combinations. Therefore, the charging product to be tested can be accurately tested under different temperature environments, and the charging conditions of different types of power supply equipment are realized. It should be noted that, for each combination, there is one corresponding test node, that is, a test result is obtained once.
In the fourth situation, the charging situations of different power supply equipment types are tested, and then the charging situations of different environmental temperatures are tested; that is, this is a combination of the first case and the second case, i.e., the test of the first case is performed first, and then the test of the second case is performed. It should be noted that, in order to further improve the test efficiency, the combined test process of the first case and the second case is merged into the same test instruction, that is, a plurality of signals for simulating the type of the charging device and a plurality of signals for simulating the ambient temperature are obtained at the same time, and only one test instruction needs to be obtained and run. In addition, in order to further improve the testing efficiency, the testing data corresponding to each testing node under the first condition can be stored and judged after the testing under the first condition is finished, and if the testing is unqualified, the testing is directly interrupted, and the testing corresponding to the second condition is not carried out any more; if the test is qualified, the test of the second case is continued. Of course, after the first case and the second case are both tested, the step S500 may be performed to determine whether the test result is appropriate. However, in the testing process, the adjustment of the testing state is the same as the first case and the second case, and is not described herein again.
In the fifth situation, the charging situations of different environmental temperatures are tested, and then the charging situations of different power supply equipment types are tested; this is similar to the fourth case, differing only in the order of testing. And will not be described in detail herein.
In the testing process, a corresponding charging environment does not need to be manufactured, the testing process does not need to be replaced, and a temperature environment does not need to be manufactured, so that the testing efficiency and the testing convenience are further improved, and the method is particularly suitable for the charging test of the charging products on a production line.
And S400, acquiring test data. The test data can be acquired by a main controller of the charging product to be tested or a charging test system, and the acquired test data comprises actual charging voltage and actual charging current. Specifically, the test data includes test data of each test node, i.e., may be performed in synchronization with step S300, or interleaved. Test data is acquired once each time a test node is executed.
Specifically, the present embodiment further includes the following steps:
s500, judging a test result according to the test data; specifically, each test data is respectively compared with a corresponding threshold range, and if each test data is in the corresponding threshold range, the test result is qualified; otherwise, the test fails. In specific implementation, the step can be executed by an upper computer in the test system, and can also be executed by a main control module of the charging product to be tested. In particular, each threshold range may be included in the test instruction, so as to facilitate modification according to different charging products to be tested during the detection process.

And S20, the charging product to be tested sets a test state according to the test instruction. Specifically, by running the test instruction, the charging product to be tested adjusts its own test state. Wherein the test state comprises a first test state and/or a second test state; the first test state is that the detection function of the type of the power supply equipment is closed; the second test state is to turn off the detection function for the ambient temperature. The setting of the test state depends on the content to be tested, for example, when the charging condition of the charging product to be tested for different types of power supply equipment needs to be tested, the test state is adjusted to a first test state, and when the charging condition of the charging product to be tested for different environmental temperatures needs to be tested, the test state is adjusted to a second test state.
