Correct lithium-ion battery charging Measures 1. High-voltage charging: This charging method does not have a special control circuit. The battery with the protector is charged directly from the 5V power supply, depending on the high pressure limit of the protector.

Features is that the start current is very large, then gradually decrease, there is a floating charge at any time; most of which can be blown up, often used in low grade plug-in card MP3, etc., high-end tolerance, do not know, I don't dare to say so expensive The term should be charged such that there are many words like this. It should be done but not doing.

2, constant pressure charging: This method is similar, constant pressure is actually the limit, set a relatively accurate maximum voltage, then Lying onto the charge, less than 4.2V vow, the rivers and lakes are called stupid, such a charger, if it is a very accurate cut-off voltage, low security, if it is high or depends on the protector, as for the bare battery. Common mobile phone universal charging and flashlight charging, this charger cost is less than $ 1, all by the inferior part of the building, Taobao retail price from 2.

00 to 15.00, how long it can be said; 3, constant current charging, this The way is still from a circuit. For the maximum charging current limit, the constant current constant pressure limit flow limits is a stupid son, a fool, such as Digititan, and Xin Wei's flow, full of flow.

After the incomplete period, with the floating flow of the trickle, it is one of the reasons why the long-term current charging is 18650 lithium-ion batteries. 4. Intelligent charging: It is currently considered an ideal charging management method.

It follows the charging algorithm described in this section, integrated in a small patch IC, the peripheral circuit is simple, stable, reliable, such as TP4054 / 4055/4056/4057, TP4002 / 5000, MAX1879, etc. The important feature of this chip is that the voltage and current can be simultaneously monitored when it is judged. 4.

2V stop charging, or the charging current is less than 0.01c (usually at about 50 mA). Stop completely after charging, do not drop the charge, monitor the voltage at any time.

If the voltage of the 18650 lithium ion battery drops to a certain value, it will start charging. The activation of lithium-ion batteries is not special, and the lithium ion battery will naturally activate during normal use. If you insist on using popular three-three-hour 12-hour charging activation, it is actually inaction.

In the case of a good protection and control circuit quality, the protection of the 18650 lithium ion battery is guaranteed. Charge according to standard time and program, even three times. 18650 Lithium Ion Battery Maintenance Measures ● Suitable temperature, prevent cold and cold.

It is best to use the ambient temperature of about 25, because the ambient temperature is too high, causing the battery to be charged with a gas, and the ambient temperature will cause the battery to overcharge. Low correct measures use 18650 lithium-ion batteries, lithium-ion battery charging methods is the most important one, because incorrect charging solutions will lead to security issues, discharge and daily maintenance impact only of the lithium-ion battery life, lithium ion battery itself Also a material, no matter what, we can prevent the loss, ultimately, we use the right way to postpone aging. ● In order to play the greatest efficiency of the lithium-ion battery, we should often use it, so that the electrons in the lithium ion battery are always in a flow state.

If you don't often use a lithium-ion battery, remember to complete the charging cycle of a lithium-ion battery monthly, make a battery calibration, that is, depth charging. ● Pay attention to the charging voltage. If the charging voltage is too high, the battery will be overcharged; otherwise, the battery will be contracted, which is harmful, pay attention to the 18650 lithium ion battery.
