Power Network News Because the lithium ion battery itself is very active, it does not have a memory effect, can be charged at any time, if it is not performed, it is charged and discharged, it will not stop itself, it will cause a charge and release without a little electricity , Will affect the life of life, all the protection circuits are not equipped with usual use. Of course, this circuit is very simple, it is necessary to control it, the highest charging voltage is controlled at 4.2V --- 4.
4V, the discharge voltage is controlled at 2.5V --- 3.0V, which we are often referred to as "lithium ion battery Protection board".
The quality of this protective board is critical, otherwise it will cause a battery explosion. After all, it is not necessary to have a strict detection to complete, which is a "lithium easy-to-power battery protective plate detector" to detect. Some difficulties in lithium-ion batteries and protective plates, it is desirable because the lithium ion battery housing is metal (steel shell and aluminum shell), the polymer lithium ion battery has only two positive and negative ears, straight electric soldering iron The temperature increases, the battery explosion is damaged, and it is also very boring to tin, so this approach is not allowed in formal use.
The normal procedure is to be welded to the top as a pure nickel plate or a nickel plated steel sheet as an intermediate mean, which recommends a WHT-328 metal spot welder. He is a pulse discharge, the time is very short, the temperature is very low, Welding does not affect battery life and performance, especially suitable for lithium-ion battery welding. However, the polymer lithium-ion battery has a very ears of aluminum, and normal welding is soldered with a CJH-1600 ultrasonic metal welding machine, which can be connected together with aluminum and nickel welding, simple method also use WHT-728 High frequency welding machine can be welded.
The lithium-ion battery itself is good or bad. The range can be, generally the internal resistance of the lithium ion battery is less than 60 luxury, the voltage is between 3.7-4.
0V. The capacity is of course, the higher the better, but the mobile phone battery on the market is virtual standard, but only the battery equipped with the imported machine will not be virtual standard, of course, many buy is not original. Usually standby time is at least 5 days, so that there is not much 3 days to call.
The battery connection process also pays attention to the static electricity. This is easy to burn the protection IC. After making a battery finished product with a protective plate, it can be applied to each electronic product, but it is usually necessary to detect, and the charging discharge and protection function are not normal.
For example, HT-301 is very applicable. Here is a slight expression for lithium ion batteries. (Power network original reprint, please indicate the source) Group: Homemade brand-name waste nickel-hydrogen battery repair process NiMH battery will have an increase in problems, and it can be said that it can be said when it is increased to some extent.
Only radio can be used! The increase in the increase in the internal resistance of the nickel-hydrogen battery is at the end of each charge, the chemical reaction of the electrolyte water in the internal joint causes the internal pressure, although most of the gas can resemble the synthetic water, but in the case of high pressure, there will be Part of gas overflows through safety valve. Over time, it is seriously short of water in the inside! Specifically, no god played a battery data recorder, I wanted to make a multi-channel voltage data recorder for a multi-channel, used to detect the parameters of the circuit board, and the upper machine software changed to change the battery data recorder. The interface has recorded only the voltage data from the original, turned into a variety of real-time parameters (including temperature, current, capacity, electricity, etc.
). The interface is as follows. Specific Laboratory Cheats: How to extend the battery life A friend of the net, due to improper charging, causing battery life to shortened, and I published I have designed and used normal charger circuits many years ago.
Can make genuine batteries once a day, charging once, can use more than half a year or more. Two models, today announced a one, the top friends have more, and another one of the automatic repairs. Data is absolutely true.
