Polymer lithium battery charging method is introduced

Source: 2020 - 03 - 25 11:50 hits: lithium polymer battery charging method at present, lithium rechargeable mainly adopts pressure limiting current limit in two ways. In the initial stages of constant current charging, accept the highest capacity of the battery. As the process continues, the polarization enhancement, temperature, voltage rise. At constant pressure stage, that is, trickle charging, to 10% of the battery need about 30% of the time. The current strength is reduced, temperature no longer increases. The process is to consider the total voltage of the battery pack or average voltage control. In fact, there is always a battery has high voltage, relative to other cells in the battery, it has entered the stage of charging. Similarly, in the process of discharge, discharge existed in the group of battery, overcharge over discharge of battery is fatal injury. Difference overcharge produces a large amount of gas, easy spontaneous combustion, explosion and appearance. Interpretation of the phenomenon change slightly, but fault extremely fast, in normal use should be strictly avoided. , there is a known as parallel control, balance management new methods of lithium ion battery, can charge and discharge of each energy saving core separate management, balance control, dynamic balance concentration balance discharge and charge balance the advantages of two kinds of balance, although the work is there a difference between monomer battery initial capacity, voltage, resistance, in the work can ensure the consistency of the charge and discharge intensity and the consistency of the relative depth gradually reached the end of life together. This method is especially suitable for large current discharge. Lithium-ion batteries, therefore, be sure to use dedicated li-ion battery charger, especially pay attention to the engineering facilities, and the parameters of the battery use should agree, the combination of lithium battery, battery protection board, must add the PCB can avoid battery specific package, discharge, fire, explosion, or even extend battery life as much as possible, but charge discharge, increase the battery recycling.
