Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.
Example 1
The application provides an embodiment I of an aging test device for a vehicle-mounted charger and a power converter, as shown in fig. 1, fig. 1 is a schematic structural diagram of the aging test device for the vehicle-mounted charger and the power converter according to the embodiment I of the application, and the aging test device 10 includes: the system comprises an industrial personal computer 101, a high-voltage bidirectional direct current power supply 102, a low-voltage bidirectional direct current power supply 103 and a low-voltage power supply 104; wherein the industrial personal computer 101 is provided with a communication module 1011, and the communication module 1011 is provided with a plurality of communication interfaces.
The industrial personal computer 101 is in communication connection with the sample machine 20 to be tested through a communication interface on the communication module 1011. In the embodiment of the present application, the number of the communication interfaces on the communication module 1011 is 4, and 3 communication interfaces are respectively connected with 1 machine 20 to be tested, and 1 communication interface can be connected with 1 machine 20 to be tested, or can be connected with another aging test device. In practical applications, the communication module 1011 may be connected to the communication interface of the test sample machine 20 and another burn-in apparatus based on CANPD (Controller Area Network Flexible Data-Rate, controller area network protocol).
Based on the communication module 1011, a plurality of communication interfaces are provided, so that the connection between the two burn-in test devices 10, i.e. the test of the batch test prototypes 20 can be realized. Because in practical application, the aging test in the product design verification stage usually needs to run synchronously with external equipment such as an incubator water bath, the power-on and power-off control requirements of the product in the process of the cyclic test are also different, and how to ensure that the batch sample machine can strictly take pictures at the same time is a key factor, the communication module 1011 is provided with a plurality of communication interfaces to realize interconnection between two aging test equipment 10, and test parameters such as the incubator water bath data are transmitted from one aging test equipment 10 to the other aging test equipment 10.
In actual operation, the industrial personal computer 101 is connected with a three-way socket, and CAN communication between the industrial personal computer 101 and the to-be-tested sample machine 20, the high-voltage bidirectional direct current power supply 102 and the low-voltage bidirectional direct current power supply 103 is realized through the three-way socket.
The power on and power off of the plurality of prototypes to be tested 20 connected by the two interconnected burn-in devices 10 can be controlled by the industrial personal computer 101. In practical applications, the cycle test of the burn-in test can be designed into different test stages and tested in the test stages, so that the test stages of the burn-in test of the batch of test sample machines 20 are consistent with the power on and power off of the test sample machines 20.
The prototype to be tested 20 includes: an on-board charger to be tested and a power converter to be tested. In the first embodiment of the application, the vehicle-mounted charger to be tested is an OBC to be tested, and the power converter to be tested is a DC/DC converter to be tested. It should be noted that, the burn-in test apparatus 10 according to the embodiment of the present application may test the vehicle-mounted charger to be tested and the power converter to be tested in the prototype to be tested 20 at the same time, or may test the vehicle-mounted charger to be tested and the power converter to be tested separately, and may be specifically determined according to actual test requirements, and the present application is not limited specifically.
As shown in fig. 1, the high-voltage bidirectional DC power supply 102 is respectively connected to the OBCs to be tested in the multiple prototypes to be tested 20, and the high-voltage bidirectional DC power supply 102 and the low-voltage bidirectional DC power supply 103 are respectively connected to the DC/DC converters to be tested in the multiple prototypes to be tested 20.
In the aging test process of the to-be-tested OBC in the to-be-tested testing machine 20, the high-voltage bidirectional direct-current power supply 102 serves as a high-voltage output connection device of the to-be-tested OBC, and plays a role of a battery simulator, namely a high-voltage direct-current power supply and a high-voltage direct-current load, and serves as the high-voltage direct-current power supply to provide high voltage for a battery at the moment of starting, and serves as the high-voltage direct-current load to play an energy consumption role in the product operation process. The OBC to be tested is connected with the HVAC alternating current mains supply, and the HVAC input of the OBC to be tested directly takes power from the power grid, so that the OBC to be tested meets the domestic actual application scene. In actual operation, in order to meet the operation of the three test sample machines 20, the model of the high-voltage bidirectional dc power supply 102 may be customized and determined according to the actual product specification and the aging test requirements.
As shown in fig. 2, fig. 2 is a schematic diagram illustrating connection between a high-voltage bidirectional DC power supply and a low-voltage bidirectional DC power supply and a sample machine to be tested, in which, in the aging test process of a DC/DC converter to be tested in the sample machine to be tested 20, the low-voltage bidirectional DC power supply 103 is used as a low-voltage output connection device of the DC/DC converter to be tested, and plays a role in vehicle-mounted low-voltage electrical appliance, namely, a low-voltage DC load, and in the product operation process, the low-voltage bidirectional DC power supply is used as a low-voltage DC load to consume energy; the role that the high voltage bi-directional DC power supply 102 plays during operation of the DC/DC converter to be tested is that of battery pack high voltage input, i.e. high voltage DC power supply.
In practical applications, the high-voltage bi-directional DC power supply 102 is compatible with the high-voltage output of the OBC to be tested and the high-voltage input of the DC/DC converter to be tested, and the sample machine 20 to be tested can realize the bi-directional output of the current, so that the OBC to be tested and the DC/DC converter to be tested can operate simultaneously or independently. In addition, due to the power taking design of the commercial power loop, the operation of the OBC to be tested can be met, and the use of high-voltage alternating current source equipment can be reduced.
In practical application, in the running process of the to-be-tested OBC, due to the application of the high-voltage bidirectional direct current power supply 102 and the low-voltage bidirectional direct current power supply 103, the consumption of the output load of the to-be-tested OBC can be directly fed back to the power grid through the high-voltage bidirectional power supply 102; in the operation of the DC/DC converter to be tested, the consumption of the output "load" of the OBC to be tested is fed back directly to the grid via the low voltage bi-directional power supply 103. It can be seen that the main power consumption of the burn-in test apparatus 10 only includes the heat loss of the fixture line and the product connection harness, the heat loss of the apparatus of the high-voltage bidirectional dc power supply 102 and the low-voltage bidirectional dc power supply 103, the heat loss of the apparatus itself during the product operation, and the power loss required for maintaining the operation of the burn-in test fixture.
The low-voltage power supply 104 is used for supplying power to the equipment requiring low voltage in the test sample machine 20 to be tested during the starting and running process of the aging test equipment 10, and has the communication control functions of current limiting/waking and the like. The low voltage power supply 104 is typically 12V. In practical applications, the number of communication interfaces provided in the number of communication modules 1011 of the low-voltage power supply 104 for the test sample machine 20 is generally the same as the number of communication interfaces provided in the number of communication modules 1011 of the low-voltage power supply 104 for the test sample machine 20, and in the embodiment of the present application, the number of communication interfaces provided in the number of communication modules 1011 of the low-voltage power supply 104 for the test sample machine 20 is all 3.
The low-voltage power supply 104, a CC (Charge Protector, a charging protector) and a CP (Charge Controller, a charging controller) form a low-voltage module, the low-voltage modules are connected with a relay control board through a first tooling opposite plug panel, and a low-voltage control switch and the like are arranged on the relay control board. The relay control board is connected with the industrial personal computer 101 through a serial port communication protocol and is used for controlling the power on and power off of each low-voltage module.
Three live wires of the relay control board are respectively connected with an alternating current AC opposite plug of the opposite plug panel through a low-voltage control switch and a second tooling opposite plug, and three rows of plugs are respectively arranged for being connected with three sample machines 20 to be tested. The high-voltage positive and negative terminals of the high-voltage bidirectional direct current power supply 102 are respectively connected with the HVDC opposite plug of the opposite plug panel of the second tool; the low-voltage positive and negative terminals of the low-voltage bidirectional direct current power supply 103 are respectively connected with the LVDC opposite plug of the opposite plug panel of the second tool. It should be noted that the first tooling opposite-inserting panel and the second tooling opposite-inserting panel are mutually different and named and are not limiting on the functions.
In summary, the embodiment of the application provides the testing equipment for the vehicle-mounted charger and the power converter, which is used for meeting the integrated testing requirements of batch vehicle-mounted chargers and power converters.
