Polymer Lithium Ion Battery Charge Method At present, lithium charging is important to limit the limiting limit. In the initial stage of constant current charging, the battery's acceptance capacity is the largest. As the charging process continues, the polarization is enhanced, the temperature is increased, the voltage increase.

In the constant pressure stage, it is the fine flow charging, and 10% of the battery charges about 30%. The intensity of current is reduced, and the temperature rise is no longer added. This process considers the total voltage or average voltage control of the battery pack.

In fact, there is always a battery with a higher voltage, and other batteries in battery packs have entered the charging phase. Similarly, during the discharge process, there is an over-discharge battery, and the damage to the battery is fatal. Difference is just a large amount of gas, it is easy to use, and the appearance is violent.

The translibration changes are mild, but the fault is very fast, and should strictly prevent in normal use. There is a combination of parallel control, balance management new lithium-ion battery charging method, can carry out two balance of each energy-saving core of charging and discharging, balance control, dynamic balance concentration balance discharge and charge balance, although The work between the monomer batteries has differential initial capacity, voltage, resistance, can guarantee the consistency of charge and discharge strength and relatively deep consistency, gradually reaching the life of the common endpoint. This method is especially suitable for large current discharge.

Lithium-ion battery, therefore, it is necessary to use a dedicated lithium-ion battery charger, especially paying attention to the engineering supporting of the battery parameters, which should agree, when combined with the lithium-ion battery, must add a PCB battery protection board to prevent Battery-specific packages, discharge, fire, explosion, even extend the life of the battery, but charge discharge, new battery recycling. .
