1. Background Analysis
Automotive electronics is a general term for vehicle body and vehicle-mounted automotive electronic control devices, including engine control system, chassis control system and body electronic control system. As a transportation tool for people to travel everyday, the most important role of automotive electronics is to improve the safety, comfort, economy and entertainment of cars. Of course, the most important one is safety. Once one of the systems or components in the car works abnormally, the vehicle cannot start at all, seriously threatening life safety. Therefore, whether it is a car or a car parts manufacturer, each part will be strictly and thoroughly tested before leaving the factory, such as sensor test, engine test, battery test, fuse test, etc.
2. How to choose DC electronic load for automotive electronics test
In the testing of related products in the automotive electronics field, many electronic loads of different specifications need to be used, and even the related software can be used to quickly and easily complete the test and obtain accurate test data. At the same time, if the electronic load used can have a communication function and an open communication protocol, and it is convenient for remote control and can be redeveloped, it will undoubtedly be an excellent choice.
ITECH Electronics Co., Ltd. (ITECH) has developed the IT8800 electronic load series that can cover diverse applications. This electronic load series combines the testing needs of various products in the automotive electronics field. The power range is from 150W-50KW, the voltage range can be up to 1000V, and the current range can be up to 3000A. It is an electronic load with flexible application and strong functionality. Can meet the various needs of the above automotive electronics testing, and has an ultra-high cost performance. The following are specific examples of the perfect application of this series of DC electronic loads in generator testing in the automotive electronics industry.
3. Application cases of DC electronic load in generator test
During the generator test, the electronic load needs to be divided into four different items from the idle speed to the full speed of the generator to simulate the power generation performance of the generator under various conditions when the vehicle is running. In this entire process, real-time observation of voltage and current data is required. The traditional load box cannot meet this requirement at all, and the test data is inaccurate. Therefore, professional electronic loads must be used for testing. So, why should I choose this electronic load series of ITECH to test the car generator? The reason is that it not only fully meets the testing needs, but also has a significant advantage.
1. Functional Overview
Any test of electronic products will have requirements for test accuracy and processing speed. In the testing of automobile generators, since the start of the generator is a short period of time, and within this short period of time, large changes will occur within the generator. Under such circumstances, engineers will of course pay attention to the sampling and recording data rate of the test instrument. This series of electronic loads use the latest CPU control technology, the internal sampling rate of the instrument is relatively high, the data update rate is also fast, the voltage / current measurement rate can be as high as 50KHZ, and its resolution can be as high as 0.1mV / 0.01 mA, so in the test of the generator, it can completely ensure the accuracy of the test. At the same time, the data in the test process, such as voltage, current, power, etc., will be displayed on the instrument panel in real time, which is convenient for real-time observation and recording, and anomalies are found in time. Digital operation interface is also convenient for setting test data.
The following figure is one of the models of ITECH IT8800 DC electronic load series (power 300W):
2. Power optional
When testing automotive generators, different tests will have different power requirements. If each test of different power uses different series of products, the differences in function and operation will cause the engineers who conduct experiments to be quite equivalent. inconvenient. Don't look at this electronic load is very small, it is only one model in the same series, there are many other models to choose from. ITECH IT8800 electronic load series, single power from 150W to 50KW, the maximum power can reach 300KW. So it can fully cover a wide range of power, meet a variety of tests, so that no matter what type of equipment It is also an experimental operation, which brings great convenience.
