[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0050] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0051] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0052] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0053] As described in the background technology, since the battery is always charged during the generator test, the battery can be quickly fully charged. At this time, the battery needs to be discharged or replaced with other batteries before the next generator test can be carried out, which affects the test efficiency and is not conducive to the assembly line test of the generator.

[0054] In view of this, the present application provides a generator performance testing device, which improves the efficiency of the generator performance test by setting up at least two energy storage modules, and a main control module controls the energy storage modules to store electricity in turn, and controls the energy storage modules that have not stored electricity to discharge.

[0055] The following is an exemplary description of the generator performance testing device provided in this application:

[0056] As an alternative implementation, see Figure 1 The generator performance testing device 100 includes a main control module 110, a discharge module 120, a data acquisition module 130 and at least two energy storage modules 140. The main control module 110 is electrically connected to the discharge module 120, the data acquisition module 130 and at least two energy storage modules 140 respectively. Each energy storage module 140 is electrically connected to the discharge module 120. The energy storage module 140 and the data acquisition module 130 are also used to connect to a generator to be tested, so as to test the performance of the generator to be tested.

[0057] When the performance test is performed on the generator to be tested, the main control module 110 first controls at least two energy storage modules 140 to store electricity in turn, and controls the energy storage module 140 that is not in the storage state to discharge through the discharge module 120. At the same time, the data acquisition module 130 can collect the current and / or voltage of the generator to be tested in the test state, and transmit the current and / or voltage to the main control module 110, and then determine whether the generator to be tested is qualified through the main control module 110.

[0058] Through the above implementation, when one of the energy storage modules 140 is storing electricity, the remaining energy storage modules 140 can all be discharged. When the energy storage module 140 is fully charged, the remaining energy storage modules 140 can also be discharged, so that the generator performance can be continuously tested, thereby improving the test efficiency.

[0059] It can be understood that the data acquisition module 130 is mainly used to collect and sense the data of the generator to be tested during operation. It can collect data through sensors. For example, the data acquisition module 130 may include a voltmeter and an ammeter, which are both electrically connected to the generator to be tested, so as to collect the voltage value and current value of the generator to be tested during operation and upload them. After receiving the data uploaded by the data acquisition module 130, the main control module 110 can compare the data with the corresponding preset value to determine whether the generator is qualified.

[0060] In an optional implementation, when the voltage of the generator under test is greater than the preset voltage value during the test, or the voltage is greater than the preset voltage value, the main control module 110 will determine that the generator under test is unqualified. For example, the preset voltage value is 15V, and the preset current value is 2A. If the voltage and current values ​​of the generator under test are detected to be 16V / 1.5A, 14V / 2.3A, and 16V / 2.3A respectively, the main control module 110 can determine that the generator under test is unqualified.

[0061] It should be noted that the present application does not limit the parameters for determining whether the generator to be tested is qualified. For example, in one implementation, only the current is used to determine whether the generator to be tested is qualified; in another implementation, only the voltage is used to determine whether the generator to be tested is qualified. Of course, in order to more accurately determine whether the generator to be tested is qualified, the data acquisition module 130 can also collect the speed and temperature of the generator to be tested during the test. On this basis, the data acquisition module 130 also includes a Hall sensor and a temperature sensor. The Hall sensor and the temperature sensor are both electrically connected to the main control module 110, and the Hall sensor is used to collect the speed of the generator to be tested when it is working, and the temperature sensor is used to collect the temperature of the generator to be tested when it is working. When determining whether the generator to be tested is qualified, the main control module 110 can make a determination based on all the above parameters. In other words, when any one of the current, voltage, speed and temperature of the generator to be tested collected during operation is greater than the corresponding preset value, the central control module can determine that the generator to be tested is qualified.

[0062] And, optionally, see Figure 2, the main control module 110 includes a main control chip 111 and a host computer 112, and the main control chip 111 is electrically connected to the host computer 112, the discharge module 120, the data acquisition module 130 and at least two energy storage modules 140. The main control module 110 is used to send data such as current, voltage, speed and temperature to the host computer 112, and the host computer 112 is used to determine whether the generator to be tested is qualified based on the acquired data and the corresponding preset value. That is, the main control chip 111 provided in this application is mainly used to upload relevant data information to the host computer 112, and at the same time send test instructions and other data to the generator to be tested, etc. The host computer 112 is mainly used to compare the acquired data with the preset value to determine whether the generator to be tested is qualified.

[0063] At the same time, in order to realize the storage and archiving of test data, the generator performance testing device can optionally also include a server 150, which is communicatively connected to the host computer 112. The host computer 112 can send the acquired relevant data to the server 150 for storage. For example, data information such as current, voltage, speed and temperature can be sent to the server 150 for storage.

[0064] In one possible implementation, the server 150 may also store information such as the serial number of the generator to be tested, so as to facilitate subsequent file retrieval.

[0065] Through the above implementation, the performance of the generator to be tested can be tested. In order to improve the test efficiency and implement assembly line testing, it is necessary to ensure that the remaining energy storage modules 140 are discharged as soon as possible when any energy storage module 140 is storing electricity.

[0066] On this basis, optionally, the discharge module 120 includes multiple discharge branches, and each energy storage module 140 is electrically connected to at least two discharge branches; when the energy storage module 140 is not in a charging state, the main control module 110 is also used to obtain the charge state of the energy storage module 140, and control the conduction number of the discharge branches according to the charge state.

[0067] Among them, the present application does not impose any limitation on the number of energy storage modules 140 and discharge branches. For example, the number of energy storage modules 140 can be 3, each energy storage module 140 is connected to 2 discharge branches, or the number of energy storage modules 140 can be 2, each energy storage module 140 is connected to 3 discharge branches.

[0068] In an optional implementation, each energy storage module 140 is electrically connected to the first discharge branch and the second discharge branch. When the state of charge of the energy storage module 140 is greater than the first threshold, the main control module 110 can control the first discharge branch and the second discharge branch to be turned on at the same time to quickly discharge the energy storage module 140; when the state of charge of the energy storage module 140 is greater than the second threshold and less than the first threshold, the main control module 110 can also control the first discharge branch or the second discharge branch to be turned on.

[0069] Generally, the energy storage module 140 can be an energy storage battery, and the energy storage battery can be continuously charged and discharged when the generator to be tested is tested. In order to improve the service life of the energy storage module 140, when the energy storage module 140 is discharged, the remaining power is generally maintained within a certain range. If the power stored in the energy storage module 140 is large, it needs to be discharged quickly to ensure that the power generated by the generator to be tested can be stored in turn.

[0070] Therefore, when discharging the energy storage module 140, it is necessary to determine the state of charge of the energy storage module 140. The state of charge refers to the SOC of the energy storage module 140, which is the ratio of the remaining capacity to the capacity of its fully charged state, and its value range is 0 to 1. When SOC=0, it means that the battery is fully discharged, and when SOC=1, it means that the battery is fully charged.

[0071] There are two ways to determine the state of charge of the energy storage module 140:

[0072] The first method is to use the sensor provided by the energy storage module 140 to detect its charge state, and the second method is to use a voltage sensor to collect the voltage of the energy storage module 140. When the main control module 110 receives the voltage of the energy storage module 140, it uses a preset voltage-charge state curve to determine the current charge state of the energy storage module 140.

[0073] After determining the state of charge of the energy storage module 140, when the state of charge value of the main control module 110 is large, it is necessary to discharge at a faster speed, and when the state of charge value is small, the discharge rate can be appropriately reduced. As an implementation method, the first threshold value can be 50%, and the second threshold value can be 40%. When the state of charge of the energy storage module 140 is greater than 50%, the main control module 110 can simultaneously control the first discharge branch and the second discharge branch to be turned on, and use the first discharge branch and the second discharge branch to discharge at the same time; when the state of charge of the energy storage module 140 drops below 50% and greater than 40%, the main control module 110 can control the first discharge branch or the second discharge branch to be turned on, and use the first discharge branch or the second discharge branch to discharge.

[0074] In addition, the main control module 110 can obtain the current voltage of the energy storage module 140, and determine the discharge time of the energy storage module 140, and then discharge the energy storage module 140 according to the discharge time, wherein the discharge time satisfies the formula:

[0075] Discharge duration = (100-SOC)*capacity of energy storage module 140 / (current voltage of energy storage module 140 / resistance of discharge branch) 2 ), where SOC represents the state of charge.

[0076] It should be noted that when the first discharge branch and the second discharge branch are used to discharge simultaneously, the resistance of the discharge branch is equal to the total resistance of the first discharge branch and the second discharge branch.

[0077] That is, the working principle of the generator performance testing device provided in this application is:

[0078] When a generator to be tested needs to be tested, the main control module 110 controls one of the energy storage modules 140 to store electricity, and at the same time, obtains the charge state of other energy storage modules 140 at this time, and controls the number of conductive branches according to the charge state at this time, and determines the required discharge time, so that the charge state of the energy storage module 140 after discharge is maintained within a certain range, for example, the charge state of the energy storage module 140 is maintained at about 50%, so as to facilitate the use of the energy storage module 140 to discharge the next generator to be tested.

[0079] It should be noted that the present application does not limit the time for the energy storage modules 140 to store electricity in turn. For example, when there are three energy storage modules 140, namely A, B and C, when the performance test of generator a is performed, energy storage module A is used to store electricity. After the performance test of generator a is completed, if it is necessary to continue the performance test of generator b, energy storage module B is used to store electricity, and the power of energy storage module A is discharged at the same time.

[0080] Alternatively, when the electric energy stored in energy storage module A reaches a threshold, the next energy storage module B will be replaced to store electricity. For example, the threshold is 80%. When the performance test of generator a is performed, energy storage module A is used to store electricity. After the performance test of generator a is completed, it is necessary to continue to perform performance test on generator b. At this time, if the charge state of energy storage module A has not reached 80%, for example, when the charge state of energy storage module A is 60%, energy storage module A will continue to be used to store electricity until the charge state of energy storage module A reaches 80%. Only then will it be replaced to use energy storage module B to store electricity.

[0081] Alternatively, only when the charging time of the energy storage module A reaches a preset time, another energy storage module B will be replaced for power storage.

[0082] It should also be noted that when the state of charge of the energy storage module 140 is reduced to a critical point, the main control module 110 can also recalculate the discharge time. For example, when the state of charge of the energy storage module 140 is 60%, the main control module 110 will control the two discharge branches to be turned on at the same time, and the calculated discharge time is 20 minutes. After 10 minutes, the state of charge of the energy storage module 140 is reduced to 50%. At this time, the main control module 110 will control one of the discharge branches to be turned on and recalculate the discharge time. For example, the discharge time is 15 minutes.

[0083] Based on the above implementation, the present application also provides an electrical connection diagram of a generator performance test device, such as Figure 3 As shown, the generator performance test device also includes an emergency stop switch and an adapter. The emergency stop switch is electrically connected to the generator to be tested. When the emergency stop switch is in a closed state, the generator to be tested stops working to exit the test state. At the same time, BAT1 and BAT2 respectively represent two energy storage modules 140. Each branch includes a relay and a cement resistor. Of course, in order to increase the flexibility of the discharge branch, the cement resistor can also be replaced by an adjustable electronic load.

[0084] When testing is required, the generator to be tested is connected to the adapter, the emergency stop switch is released, and one of the energy storage modules is controlled, for example, BAT1 is controlled to store electricity. At the same time, the relevant parameters of another energy storage module BAT2 are obtained, and the branch is turned on by controlling the relay in the discharge branch of BAT2, thereby achieving discharge.

[0085] In addition, as an implementation method, the generator performance testing device also includes an ambient temperature control module 160, which is electrically connected to the main control module 110; wherein the ambient temperature control module 160 can obtain the ambient temperature of the generator to be tested; the main control module 110 can also control the ambient temperature of the generator to be tested according to a preset temperature.

[0086] That is, the ambient temperature control module 160 may include an ambient temperature sensor and an ambient temperature regulator, such as an ambient temperature regulator such as air cooling or water cooling. On the one hand, by setting the ambient temperature control module 160, the ambient temperature of the generator to be tested can be adjusted, so that the generator to be tested can operate more efficiently. On the other hand, the ambient temperature control module 160 can also be used to simulate special environments. For example, when the generator is used in a relatively cold area, in order to simulate its actual application scenario, the ambient temperature during the test process can be lowered.

[0087] Based on the above implementation method, an embodiment of the present application provides a generator performance testing system, which includes a generator to be tested and the above-mentioned generator performance testing device, the generator performance testing device is connected to the generator to be tested, and the generator performance testing device can be used to test whether the generator is qualified.

[0088] See also Figure 4 The embodiment of the present application further provides a generator performance test method, which is applied to the main control module of the above-mentioned generator performance test device, and the method comprises:

[0095] When the state of charge of the energy storage module is greater than a first threshold, the first discharge branch and the second discharge branch are controlled to be turned on simultaneously to quickly discharge the energy storage module.

[0096] When the state of charge of the energy storage module is greater than the second threshold and less than the first threshold, the first discharge branch or the second discharge branch is controlled to be turned on.

[0097] In addition, the steps of S1042 also include:

[0098] When the energy storage module is not in a power storage state, the current voltage of the energy storage module is obtained, and the discharge time of the energy storage module is determined, so as to discharge the energy storage module according to the discharge time, wherein the discharge time satisfies the formula:

[0099] Discharge time = (100-SOC)*capacity of energy storage module / (current voltage of energy storage module / resistance of discharge branch) 2 ), where SOC represents the state of charge.

[0100] The data acquisition module is also used to collect the speed and temperature of the generator under test in the test state, and transmit the speed and temperature to the main control module; wherein the step of determining whether the generator under test is qualified includes:

[0101] When any one of the current, voltage, rotation speed and temperature is greater than the corresponding preset value, it is determined that the generator to be tested is qualified.
