“…Recently, the lithium-breed batteries gradually replace other types of batteries due to their advantages of higher voltage level, long service life, nontoxic and no pollution, and are widespread exist in a variety of hand-held electronics [1][2][3][4][5]. As discussed in [3,[6][7][8][9][10][11][12][13][14][15], lithium batteries can be damaged by many conditions, such as excessively high or low voltages, and in some cases the results can be catastrophic. For example, if their voltages become too high, they will ignite, which equates to an over-charged condition.…”

In order to cut the costs and overcome the leakage current of batteries caused in traditional method, this study introduces an improved voltage transfer method for lithium battery string management chip. This proposed circuit based on the improved voltage transfer method is fabricated in 180-nm Bipolar-CMOS-DMOS is correct technology, and has been successfully applied to a three lithium batteries string management chip. These measurements indicate that this circuit transfers each cell's voltage reliably and adopt protection against abnormal conditions. Furthermore, analysis of 50 samples shows that the improved method can greatly eliminate the battery leakage. The circuit reduces the leakage current to nanoampere scale and is integrated into the lithium battery string management chip, which is helpful for battery voltage balance and low cost.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
