How to correctly know the lithium-ion battery overcharge? People often have a misunderstanding when charging: insist on full state is the best. When the battery is raised from 100% to 99%, obsessive disorder may make you duty, but I don't actually recommend you charge your mobile phone, especially after the phone is full of electricity. Lithium-ion batteries are not a lot of people who have a lot of ages, always tell you when you get the first mobile phone, new mobile phones must first complete all discharge, then charge 12 hours, then completely discharge, to repeat 3 times.

At the beginning, you must be old and old, but in fact, the smartphone that has already been used with lithium-ion batteries is no longer necessary to have such a labor maintenance process. NiMH batteries need to charge multiple times. This battery has a strong memory.

The process of charge and discharge is also to make the nickel-hydrogen battery to the maximum charging limit. But now the phone is used by lithium-ion batteries, there is no need to repeat such complex battery recall process. So will the lithium ion battery keep the maximum charge limit? The answer is definitely negative.

Although the lithium-ion battery is known for its use, it will lose the unpretable upper limit during repeated battery cycle charge, which is composed of one point. In addition to normal charging, overcharge is the first evil. How to understand how to overcharge excessive charge is actually very understanding, that is, the mobile phone is still charging to the mobile phone battery in a state full of battery, which time we call mobile phone over.

When the battery is full, continuous charging can cause the structural change of the negative electrode material, resulting in loss of component capacity. However, the separation of oxygen and electrolytes will cause severe chemical reactions, the worst result is explosion. They work very hard to prevent excessive charging, and now most mobile phones have IC protection.

The charger itself also monitors voltage and current. Drop-bearing charging is often used in mobile devices to protect batteries and users. When charging is charged with a USB interface, it is assumed that the line loss is not considered.

USB charging port will charge charging with the mobile phone and match the appropriate current to ensure that the phone does not lose most of the current due to the input high current. When the battery is low, if 10% is left. In addition to the mobile phone battery supplies, there is another way to rely on charging socket to prevent overcharge.

It is necessary to supply power to the outlet, prevent overcharge, to supply a stable voltage, the less voltage, the current will be affected. Especially when my country's night voltages are unstable, it is very important to ensure that the stability of the USB interface output voltage is very important. In general, the voltage of the USB charging port is 5V.

Some USB charging ports that can be intelligently allocate, when the mobile phone battery is close to full charge, slightly lower the voltage of the charging port, thereby reducing the input current, alleviating battery pressure. These methods have good suppression purposes on the overcharge of mobile phones, but the bottom is still because we did not unplug the power, let the phone continue to repeat the discharge and charging process, resulting in reduced capacity caps. Tough charge is not small things about the average life of mobile phone users.

It is really not a small thing. The battery life of the mobile phone directly affects the moment you use your mobile phone. It is assumed that the phone is arbitrarily charged, the trust is less than a year.

Be dead. If you can see that the current battery is a little swelling, it may be overchargeful. To be big, the charging is over or directly affects your safety, and the cottage battery can guarantee what will not put fireworks.

If you are going to prevent excessive charging, it seems to be controlled. .
