In a series-operated battery pack, a plurality of batteries (104, 108, 54) are usually connected in series, and the voltage and the internal resistance of the battery during operation need to be measured periodically according to the requirements of regulations, and the battery needs to be measured once per hour in a check discharge test. Typically, the measurement work requires 2 people to perform work, i.e., one person to measure and one person to record, using a multimeter or internal resistance tester. The average measurement of the voltage of a group of storage batteries (104) takes about 25 minutes, the measurement of the internal resistance takes 35 minutes, and repeated measurement operation seriously wastes the cost of manpower resources. The storage battery online measurement is used as the only method for replacing repeated measurement at present, and because of long-time operation, the device cannot verify the accuracy, so that the measurement error is gradually larger, the storage battery online measurement cannot be used as a measurement basis, and finally, a universal meter or a handheld internal resistance tester is needed to be used for measurement.

When the space is narrow or the position is higher, the operation of holding the test meter pen by both hands is very inconvenient, the measurement instrument is easy to drop or the test meter pen is easy to pull and damage in the measuring or moving process, and the operation process is inconvenient; 2. measurement efficiency is low, and an average measurement of the voltage of a group of storage batteries (104) takes about 25 minutes, and an internal resistance measurement takes 35 minutes. In the checkup discharge, calculated as measured voltage 1 time for 25 minutes, the entire discharge test requires 10 measurements, and then a total of 250 minutes is required. That is to say, the whole discharge test has 4.3 hours to constantly measure the voltage of the storage battery, and the operation is highly repeated, so that the working efficiency is low; 3. the measurement record is not scientific, the measurement work needs to be operated by 2 people by using a universal meter or an internal resistance tester, namely one person measures one person record, and the measurement record is paper, so that the analysis and the storage of the measurement data are inconvenient, the current large data informatization development requirement and direction are not met, and the measurement record is not scientific.
