How does the mobile phone charger wholesale factory improve production efficiency?

July 2, 2019 by keikeilaiy  

Speaking of mobile phone chargers, I believe that everyone will not be unfamiliar. The mobile phones we use every day need to be charged. Since we need to charge, we need our chargers. Many of the devices now require chargers, not just Mobile phones, such as computers and so on. Therefore, if the charger is used, it is mainly to see which aspect of the mobile phone charger wholesale factory is made. For the charger of the mobile phone, its internal electronic components use a lot of patches, and can also be used for automatic soldering, and Inspection and repair.

However, if it is a charger such as an electric car, there are many common internal components, and there are many large components inside. We can use machine plug-ins and manual installation. Because of the different battery products, it requires different methods to continue charging, so you must remember to charge according to the product instructions. The initial nickel-metal hydride battery was similar to activation. Because the battery will generate memory, if it is charged under the condition of not completely discharging, it is easy to make the battery excessively full, so that after a long time, the user will feel that the power of the mobile phone is quickly used. It’s over. However, most of the batteries used in current notebook computers, mobile phones, etc. are lithium-ion batteries. So its initialization is done at the time of manufacture. The advantage is that you don't need to activate it when you start using it.

1, good safety performance

The polymer lithium battery is made of aluminum plastic flexible packaging, which is different from the metal outer casing of the liquid battery. Once the safety hazard occurs, the liquid battery is easy to explode, and the polymer battery core can only be air drum.

2, light weight

The weight of the polymer battery is 40% lighter than the steel shell lithium battery of the same capacity specification, which is 20% lighter than the aluminum shell battery.

3, the thickness is small, can be made thinner

Ordinary liquid lithium battery adopts the method of customizing the outer casing first, and then plugging the positive and negative materials. The thickness is 3.6mm or less, there is a technical bottleneck. The polymer battery core does not have this problem, and the thickness can be less than 1mm, which meets the needs of current mobile phones. direction.

4, the shape can be customized

Polymer batteries can increase or decrease the thickness of batteries according to customers' needs. Develop new battery models, which are cheap, open cycle is short, and some can even be customized according to the shape of mobile phones to make full use of battery casing space and upgrade batteries. capacity.

5, large capacity

The polymer battery has a capacity of 10-15% higher than that of the same size steel shell battery, which is 5-10% higher than that of the aluminum shell battery. It is the first choice for color screen mobile phones and MMS mobile phones. Nowadays, the new color screen and MMS mobile phones on the market are mostly used. Polymer batteries.

6, the protection board is simple in design

Due to the use of polymer materials, the battery core does not ignite or explode, and the battery core itself has sufficient safety. Therefore, the protective circuit design of the polymer battery can be omitted by omitting the PTC and the fuse, thereby saving battery cost.

7, good discharge characteristics

The polymer battery uses a colloidal electrolyte, which has a smooth discharge characteristic and a higher discharge platform than a liquid electrolyte.

8, small internal resistance

The internal resistance of the polymer battery core is smaller than that of the general liquid battery. At present, the internal resistance of the domestic polymer battery core can even be less than 35mΩ, which greatly reduces the self-consumption of the battery and prolongs the standby time of the mobile phone. The level of integration with the international. This polymer lithium battery that supports large discharge currents is an ideal choice for remote control models and is the most promising alternative to nickel-metal hydride batteries.

How to solve the problem that the mobile phone charger can not be charged

May 24, 2019 by keikeilaiy  

No matter how advanced technology is, how to change smartphones, at least on the smartphones currently in use, the use of mobile phones is inseparable from "electricity." Even if it is a folding mobile phone that will be on sale, it still needs to be charged before it can be used normally. Therefore, for mobile phones, "having electricity" is crucial. However, the "electricity" has also caused a lot of troubles for many mobile phone users, especially the mobile phone charger can not charge for this point, many users have said that "the same disease." After all, the charger of the mobile phone suddenly fails to charge, is it for what reason? How should we deal with it? Mobile phone charger wholesale factory tells you how to solve the problem that the mobile phone charger can not charge


The first reason: there is a problem with the charging interface of the body

Although many mobile phone manufacturers now launch smart phones with no-hole design, they have not yet "occupied" the user market. Therefore, for the smartphones that are now commonly used, most mobile phones support wired charging technology, which further demonstrates the importance of the "charging interface". Such a charging port is often one of the designs that are easily damaged. For example, it is accumulated and blocked by tiny debris such as dust from the outside, and therefore, it is easy to affect the user's wired charging. If your phone doesn't charge, you can check if there is any obstruction in your charging port. If it is, it is recommended to use a fine tool that is not sharp, non-humid, or high temperature to clean it, but in case of accident, take it to a professional repair shop for repair.

The second reason: there is a problem with the charging cable

When the mobile phone can't normally use the normal charging work, if the environmental conditions permit, you can ask the people around you to borrow a charging cable that can also charge your mobile phone, and then try to finish the charging work. If you can, then there is a problem with your data cable and you need to replace the new data cable. The following is how to choose the charging cable. In the market, the data lines are often of high quality. Firstly, the external workmanship is more meticulous, and the edges of the plug are free of burrs and resistance. Dirty data lines; then from the inside to examine - select those data lines with good plug-and-play experience, strong current transfer capability and short charging time.

Reason 3: There is a problem with the charger

How can I check if the problem is caused by the charger failure? The charger can be separated from the data line, and then the mobile phone can be charged through the data line by other means. If the mobile phone can perform the charging work normally, the charger often has a problem. To do this, the user needs to replace the charging head. The following is a suggestion on how to buy a good quality charging head. Experts believe that for electronic technology products, the choice of replacement items is always original, so the charging head is no exception. . However, if you are interested in choosing a non-original charging head, then experts recommend that you choose a product that is produced by a regular, qualified manufacturer, and that you choose a product that is of good quality and relatively well-known. At the same time, it is necessary to pay attention to whether the current of the selected charging head is similar to the current of the original charging head. In order to provide better safety protection for the mobile phone, it is necessary to select plugs with the same or similar current.

The fourth reason: the phone system settings are faulty

If the above reasons are all ruled out, it is very likely that the settings of the mobile phone system have failed. If this is the reason, it is recommended to contact the mobile phone manufacturer for post-sale maintenance, and then take the regular mobile phone repair shop for maintenance. Of course, in addition to the above suggestions, according to industry insiders, there is a self-operating method, but if your mobile phone wants to continue to use, regardless of the new machine, or can not take risks, do not take the following actions -

Mainly for user phone settings for Android:

First make sure that the phone has backed up all the data, and then confirm that the phone has obtained the "ROOT" permission - enter the Android phone into "Recovery" mode → "Wipe" → "wipe battery status"; after completing the above steps, restart the phone (ie reboot) it will be fine.
