Problems solved by technology

[0002] In the existing storage battery grouping method, the battery cells are combined in series to boost the voltage. Due to the current production technology and process limitations of the battery, it is common that the technical indicators of the battery cells are not consistent. Therefore, After being connected in series, the single batteries interact with each other during the charging and discharging process, causing the working life of the battery pack to be much shorter than that of the single batteries; A balancing and measurement and control branch is connected in parallel to the two poles of the battery. Under the monitoring and control of the microprocessor and the measurement and control branch, the external characteristics of the single batteries in the series tend to be consistent, thereby improving the life of the series battery pack; Yes: The effective working range of the equalization and measurement and control branch is limited and the circuit is complex, and the life and index changes of the single battery will still affect the life of the entire series battery pack

Description

technical field [0001] The invention relates to a group working method of single accumulators and an independently working battery pack, belonging to the technical field of accumulators. Background technique [0002] In the existing storage battery grouping method, the battery cells are combined in series to boost the voltage. Due to the current production technology and process limitations of the battery, it is common that the technical indicators of the battery cells are not consistent. Therefore, After being connected in series, the single batteries interact with each other during the charging and discharging process, causing the working life of the battery pack to be much shorter than that of the single batteries; A balancing and measurement and control branch is connected in parallel to the two poles of the battery. Under the monitoring and control of the microprocessor and the measurement and control branch, the external characteristics of the single batteries in the s...
