The lithium iron phosphate ion battery pack of new energy vehicles is usually two key indicators that have a cell composed of many cells: one is a battery capacity, and one is a bowl of capacity, one is a battery-loaded state (ie Commonly known as the remainder, hereinafter referred to as SOC) can be seen as a water in the bowl, for example, 50ml bowls of 25ml of water at this time, SOC at this time is 50%, and the lithium iron phosphate ion battery pack offline all electricity The capacity of the core is basically consistent, but all the cells in this state can be synchronized and released step adjustment clean, consistency, general storage or factory SOC remains around 10 ~ 20%. When the lithium phosphate ion battery is stored or factory, the SOC is about 10% to 20% but with the new year of use and the number of charging, the interior of the lithium iron phosphate ion battery is unfained to change the capacity of each cell or SOC. There is an uneven phenomenon, depending on the principle of the wooden bucket, a flat wooden barrel can be installed by the short board, the capacity of the lithium iron phosphate ion battery pack is also the same.
Tumbele short plate effects indicating that all cells are synchronous charge and discharge in the case of battery cell capacity or SOC, as long as there is a battery to fill or remove other cells, they can no longer continue to charge and discharge, because if it continues to charge and discharge The battery that caused a small capacity has an overproduction, which causes lithium ions in the core to change the internal structure of the cell to cause damage to the internal structure of the cell, and reduce the life of the lithium iron phosphate ion battery pack. When the dangerous event such as fire, the small capacity or SOC battery is equivalent to a short wooden board inside the lithium phosphate ion battery, which leads to a reduction in the total energy stored in the lithium phosphate ion battery pack, which is shortened. This is Wooden bucket principle inside the lithium iron phosphate ion battery pack.
What is the original cause of the lithium iron phosphate ion battery charging deadline (the capacity small electrical core is automatically protected) What is the original difference between the cell between the cell? As the saying goes, I want to treat the disease first. I don't have three differences. I have three kinds of considerations of the core: SOC is consistent, the capacity is inconsistent.
This state is the same as the margin of the bowl. It has a gap. It can only load 50ml water, but now only 40ml Otherwise, it will be leaking from the gap.
At this time, the first volume of capacity is the bottleneck of the entire lithium iron phosphate ion battery pack. Trying to the first figure, the first three-segment capacity of the front of charging is 50%, SOC is The current power is half the amount of electricity, so the lithium phosphate ion battery assembly pack satisfies a condition, capacity consistency, and different capacity cells cannot be mixed. The lithium phosphate ion battery SOC is consistent, but the capacity is inconsistent with the same amount of electricity, the battery cell is small, and the battery cell cannot be charged, because if it is sustained, the charging core will pass Charging long-term overtakes, even dangerous events such as battery.
The capacity is not a lithium iron battery, and when the battery is discharged, the battery cell is discharged, and the battery cells are small, and it is not possible to continuously discharge, which will be discharged for a long time. Putting to cause damage to the internal structure of the battery. .
