Reasons for failure of battery internal resistance tester or battery state tester
Batteries are already common in our lives, and the application range of batteries for home appliances and automobiles is very wide. The battery is the core component of the car’s electrical system. If the engine is the heart of the car, then the battery is the key to activating the heart. Not only that, the battery will continue to power many electrical appliances and safety and comfort systems during driving, so the battery is in our Plays a very important role in life.
What is the reason for the failure of the battery resistance tester or battery condition tester? ? How much do you know about this problem? ? Today, the editor of Zhengzhou Kanglida Electronic Power Supply Co., Ltd. will give you some information on this issue. I hope it will be helpful to you. In the future, you can avoid detours when using and purchasing.
1. Use an internal resistance meter instead of a discharge meter to judge the retained capacity, and it turns out that the results are very different. Earlier, the retained capacity I mentioned is not equal to the state of charge, and the retained capacity is equal to the product of the state of charge and the rate of change of internal resistance. The capacity value given by the internal resistance tester is the inherent capacity, and the discharge meter checks the retained capacity, so there will be discrepancies. If it is assumed that the battery is in a 100% charged state, the inherent capacity is equal to the retained capacity. Because of the space, I I can’t expand on this issue. Our smart battery condition tester has the function of calculating the retained capacity. We have verified the reliability of the test at Wanli Battery Factory. But not all internal resistance meters have this function. Please ask clearly when choosing .

2. The method used is wrong. When judging, use the standard value recommended by the instrument manufacturer to judge a good battery as a bad battery, and a bad battery as a good battery. The battery actually has no sense of standard internal resistance, and the same capacity The internal resistance value of the same type of battery is different. Many domestic experts have spent a lot of time to prove this conclusion. Our internal resistance meter does not rely on standard values to judge the health of the battery, IEEE1188-2005 standard The above also refers to the initial value of the internal resistance of the battery. What needs to be corrected here is that the internal resistance value we said is actually just a judgment equivalent.
3. The instrument itself is not easy to use. The test consistency of the purchased equipment is not good, and the temperature drift is too large. For some internal resistance meters, for the same battery, the test contact points are different, and the measured internal resistance value can be more than doubled. The difference between the first test value and the tenth test value may be doubled. Such an instrument cannot be used to judge the health of the battery.
