lithium batteries / lithium polymer battery, charging balance planning,
circuit design The so-called charge balance plan, the basic concepts in the series when charging lithium batteries, because health and material characteristics of the battery is different, so it is necessary for charging the moment, be the immediate concern, So that every single cell will get individual attention, making fully charged battery, the battery voltage conditions can be quite full. Avoid the repeated charging, the battery because of individual differences, resulting in a gap, lengthen the time, String lithium battery charge and discharge string, face fall, causing shortened life expectancy. Single lithium battery, the battery specification 4.2V (Two strings) two lithium batteries, battery specifications 8.4V (Trebles) three lithium batteries, battery specifications 12.6V (Four strings) four lithium batteries, battery specifications 16.8V (E string) five lithium batteries, battery specifications 21V (Six strings) six lithium batteries, battery specifications 25.2V String string discharge the battery charge is very common, but if the whole system, not in the case of prior consideration, Will inevitably lead to the charging and discharging cycles of life, it is inevitable that, after all, the material properties of every single cell, it is difficult identical. Often appears the case: 1. The more stars rechargeable batteries in series, some full battery voltage is particularly high, some of the battery is very low. 2. Multi-cell battery discharge series, particularly when certain pieces of low battery discharge. 3. The more stars discharge batteries in series, when certain pieces of battery discharge is drained, <2V damage. Division I entrusted the design, according to customer demand, according to the charging time, the series, the design is not the same as the charging infrastructure to meet system requirements. High pressure and low flow, low pressure, high flow, power characteristics, all kinds of different needs, adjust structure and circuit design, complete end to see the needs to design and planning.
