Application of Battery Test System in Automobile Battery Testing

With the popularization of automobiles, the safety of automobiles has become more and more important. The abnormality of a system or component in a car may lead to serious consequences. Therefore, it is very important to do a good job in automotive electronics testing. Today's introduction of a test program for automotive electronic batteries not only works in CC but also in a variety of other modes. It also satisfies arbitrary editing of waveforms based on test requirements.

Nowadays, more and more alternatives for fuel-engine vehicles are being implemented. The most practical and commercially viable model is hybrid vehicles. The battery it uses is tested in CC mode. For professional testing, a variety of discharge and charging modes are necessary.

1. Modular design, testing 200 batteries simultaneously

The Car Battery to be tested is changing. When this change occurs, the specifications of the test system must be adjusted accordingly. The IT9600 battery test system of ITECH adopts a modular design, which can easily expand the specifications of the test system, freely match the most suitable test system, and reduce waste. The indispensable test of battery capacity, discharge characteristics, cycle life and many other automotive batteries can be performed by the ITECH IT9600 Battery Test System. When faced with different tests, there is no need to select other test systems. Using this battery test system to complete the testing of a variety of automotive batteries provides great convenience while also greatly saving costs. And can use IT9600 battery test system to achieve simultaneous testing, real-time monitoring and recording of up to 200 batteries.

2. A variety of charge and discharge modes to meet the fuel cell test requirements

In order to meet the high-precision test requirements of the fuel cell, the minimum discharge voltage of the battery test system can be set lower than 0.1V, and can reach 240A discharge current at 1.2V, and the minimum resolution of the discharge current is 0.1mA, with an accuracy of 0.1%. High-precision discharge can be done. The battery test system can also automatically draw the curve of voltage, current, and other changes over time in the discharge process to facilitate analysis of data.

In addition, in order to make the testing of fuel cells more convenient and accurate, this IT9600 battery test system from ITECH also provides a variety of operating modes. Among them, the charging modes include constant current (CC), mixed constant current, and constant current. Voltage (CC+CV); Multiple discharge modes include constant current (CC), constant resistance (CR), and constant power (CP).

3. Battery test system setup

How can we build an IT9600 battery test system to complete the automotive battery test? It consists of a DC power supply, a DC electronic load, and an IT9300 test software (power supply, electronic load, and test software are all from ITECH Electronics Co., Ltd. ITECH). After the installation, the battery test system can be built. Communicate with computers to meet various testing needs.

4. Test automation

Take the test of a single battery as an example, it needs to be charged, shelved, discharged, discharged, and cycled several times. This is a long process. It is quite unrealistic if the whole process is monitored by engineers. of. ITECH's IT9600 battery test system allows unmanned monitoring and automation of battery testing. The following is the software monitoring interface of the system. The number of channels can be flexibly configured according to actual test requirements. Up to 200 batteries can be tested at the same time. The green channel is configured as follows:

to sum up

The automotive electronic battery test program is an application case from ITECH's DC power supply and DC electronic load with its designed test software in the automotive electronics industry. Not only that, but it is believed that the application of the battery test system is not limited to the testing of related products in the automotive electronics field, but it can also be extended to any similar battery test in other electronics industries to provide the most convenient for engineers. The most optimized battery test solution.
