Low-cost automotive electronic battery testing solution

With the popularity of automobiles, the safety of automobiles has received more and more attention. The abnormality of a system or component in the car may lead to serious consequences. Therefore, it is particularly important to do a good job in testing automotive electronics. Today, an automotive electronic battery test solution introduced can not only work in CC and various other modes, but also meet the requirements of editing waveforms according to test requirements.
Application of battery test system in automotive battery testing

Nowadays, there are more and more solutions to replace fuel engine vehicles. The most practical and commercially operated mode is hybrid vehicles. The batteries used in it are mostly tested in CC mode. If professional testing is to be performed on them, a variety of discharge and charging modes are necessary.
1. Modular design, testing 200 groups of batteries at the same time

The automotive batteries to be tested are changing. When such changes occur, the specifications of the test system must be adjusted accordingly. The ITECH IT9600 battery test system adopts a modular design, which can easily expand the specifications of the test system, freely match the most suitable test system, and reduce waste. Various tests that are indispensable for automotive batteries, such as battery capacity charging characteristics, discharge characteristics, and cycle life, can all be completed by the ITECH IT9600 battery test system. When facing different tests, there is no need to choose other test systems. This battery test system can be used to complete the test of various automotive batteries. It provides great convenience and greatly saves costs. And the IT9600 battery test system can be used to achieve simultaneous testing, real-time monitoring and recording of up to 200 groups of batteries.

2. Multiple charging and discharging modes to meet the needs of fuel cell testing

In order to meet the high-precision test requirements of fuel cells, the minimum discharge voltage of the battery test system can be set to less than 0.1V, and the discharge current can reach 240A at 1.2V, and the minimum resolution of the discharge current is 0.1mA, with an accuracy of 0.1%, which can perform high-precision discharge. The battery test system can also automatically draw the curves of voltage, current, etc. changing with time during the discharge process, which is convenient for data analysis.
In addition, in order to make the test of fuel cells more convenient and accurate, the IT9600 battery test system of ITECH can also provide multiple working modes, including charging modes including constant current (CC), mixed constant current + constant voltage (CC+CV); multiple discharge modes including constant current (CC), constant resistance (CR) and constant power (CP).

3. Battery test system construction

How to build the IT9600 battery test system to complete the test of the car battery? It is built by a DC power supply, a DC electronic load and an IT9300 test software (the power supply, electronic load and test software are all from ITECH Electronics Co., Ltd.). After the completion of the construction, the battery test system can communicate with the computer to meet various test requirements.

4. Test automation

Taking the test of a single battery as an example, it generally needs to go through the process of charging, shelving, discharging, discharging stop, and cyclic charging and discharging for several times. This is a long process. It is quite unrealistic if the whole process is monitored by engineers. ITECH's IT9600 battery test system can achieve unmanned monitoring throughout the process and realize the automation of battery testing. The following is the software monitoring interface of the system. The number of channels can be flexibly configured according to the actual test requirements. Up to 200 batteries can be tested simultaneously. The green channels in the following interface have been configured:

In summary

, this automotive electronic battery test solution is an application case of the DC power supply and DC electronic load from ITECH Electronics Co., Ltd. (ITECH) with its designed test software in the automotive electronics industry. Not only that, it is believed that the application of this battery test system is not limited to the testing of related products in the automotive electronics field, but can also be extended to any similar battery tests in other electronics industries, providing the most convenient and optimized battery test solutions for engineers.
