With the rapid development of communication, energy resources, power supply system, and electronic computer big data center, the use of batteries, which are the key components of DC regulated power supply, has also increased rapidly. Let's take a look at the measurement of battery internal resistance testers. What are the methods?

1. Verification discharge method (on time verification discharge experiment)

The verification discharge method is a complete deep discharge. It has the advantages of accurate, safe and reliable capacity detection. Therefore, it is still a relatively safe and reliable way to test the battery characteristics in the world. The verification discharge method is the capacity experiment of full discharge, which is to test the battery capacity. In a more direct and safe and reliable way, the discharge meter confirms the capacity and condition of the battery very accurately.

2. Conductance or internal resistance measurement method (generally used for daily maintenance)

Portable battery internal resistance tester, the key at this stage is the daily maintenance of equipment. The smaller the battery capacity, the larger the battery resistance, and the smaller the conductance value. The conductance or internal resistance method can accurately detect completely invalid batteries. According to many experimental analysis and analysis results, it is confirmed that when the capacity of the battery is only reduced to 50%, the internal resistance or conductance will change to a certain extent, and after it is reduced to 40%, there will be a significant change. It is the internal resistance value, which can confirm the characteristics of the battery at a certain level. The use of the conductance or internal resistance method to detect the internal resistance or conductance of the battery is a valuable reference concept for judging the quality of the battery. The detection work is very simple, but because the internal resistance and capacity are linear systems, the detection results cannot effectively reflect the real physical condition of the battery.

The above is an introduction to the operation method of the battery internal resistance tester, I hope it can help you.
