Application principle of Battery Equalizer with smart battery app voltage display

(Summary description)One of the most important "treatment processes" is "battery equalization" or called battery equalization repair. The main equipment is Battery Equalizer with smart battery app voltage display.

Information

The attenuation of the battery is generally divided into two categories. One is the irreversible attenuation caused by the loss of chemical substances inside the battery, which is also called battery aging. When the climate temperature changes or the battery cells are inconsistent, the battery performance and cruising range will decrease. It is called reversible attenuation. Since the attenuation is "reversible", there are ways to delay or recover. The climate temperature change can be solved by constant temperature control. At this time, the situation of "battery inconsistency" requires BMS Device to rejuvenate the battery cells. ". One of the most important "treatment processes" is "battery equalization" or called battery equalization repair. The main equipment is Battery Equalizer with smart battery app voltage display.

New energy (wind energy, solar energy) battery packs usually consist of many batteries and a Battery Equalizer with smart battery app voltage display. There are two key indicators for investigating batteries: one is the capacity of the battery, which can be regarded as the capacity of a bowl, and the other is the state of charge of the battery (commonly known as the remaining power, hereinafter referred to as SOC), which can be regarded as the content of water in the bowl. For example, when a 50mL bowl contains 25mL of water, the SOC at this time is 50%. When the battery pack is offline, the capacity of all cells is basically the same as the SOC. Only in this state can all cells be fully charged and emptied simultaneously. The steps are adjusted and the consistency is good. Generally, the SOC stored or shipped from the factory is maintained at about 10-20%.

However, as the service life and the number of recharges increase, the internal changes in the battery will inevitably occur. The capacity or SOC of each battery cell will produce unevenness. According to the principle of wooden barrels, a flat wooden barrel can hold the amount of water. The shortest board determines the capacity of the battery pack as well.

All cells are charged and discharged synchronously. In the case of inconsistent cell capacity or SOC, as long as one cell is fully charged or emptied, other cells cannot continue to be charged and discharged, because if you continue to charge and discharge, it will result in a battery with a small capacity. The phenomenon of overcharge and overdischarge of the core may cause the lithium ions inside the battery cell to become lithium elemental precipitation, which causes the internal structure of the battery cell to be destroyed and reduce the life of the battery pack. In the worst case, it may cause dangerous events such as battery fire. Or SOC cells are equivalent to the "shortest wood board" inside the battery, which reduces the total energy stored in the battery pack and shortens the available cruising range. This is the "barrel principle" inside the battery pack. You can view the display on the Battery Equalizer with smart battery app voltage display device

Batteries, Battery Equalizer with smart battery app voltage display There are three external variables that can be measured in real time, voltage, current and temperature. The variable information is introduced into the algorithm to get the SOC value of each battery cell and the available capacity of the battery at this time, and Based on this comprehensive judgment of the inconsistency between the cells to determine whether the battery pack needs to enter the equilibrium state, the battery balancing technology is mainly divided into two types of passive balancing and active balancing. Regardless of whether it is active or passive equilibrium, how to make each bowl fill as much water as possible, and at the same time, it is the ultimate goal of Battery Equalizer's strategic design to empty the bowl of water as much as possible.
