Automatic detection system for electrical parameters of secondary battery pack

Abstract

The invention relates to an automatic detection system for electrical parameters of a secondary battery pack, and are mainly applied to production and processing of different types of secondary battery packs. According to a common parallel and then serial connection mode of the battery pack, the system can set different detection parameters and procedures for different types of batteries, the system can detect, record and store electrical parameters of the whole battery pack as well as single battery units, and accurate data is provided for special production schemes in the finished battery pack production process. Electrical cores detected by the system need not to be completely consistent in electrical capacities as internal resistance and capacity, instead, the electrical parameters ofthe same type and model of electrical cores only need to be within the allowed range; the technical problems that there are too many procedures, matching is inconsistent, and the electrical parametersof different units in the battery pack are deviated in the long-time using process in the background art are solved; and the system is especially suitable for production and processing of lithium batteries and other novel secondary battery packs.

Problems solved by technology

[0002] With the development of science and technology, secondary battery packs are used more and more widely as DC power supplies. Currently, the production of battery packs is generally recognized by using various equipment and instruments to measure, calculate, and sort the parameters of each single cell. A variety of processes are labor-intensive and time-consuming, and the electrical parameters of each sub-unit of the finished battery pack will deviate during normal use, especially for lithium batteries due to their own particularity, the charging valve of the battery cell during charging and discharging. The value and the discharge threshold are protected by the circuit, and each sub-unit in the battery pack cannot be close to being fully charged and discharged at the same time, so that the power of the battery pack cannot be fully utilized.
