The mobile power source is mainly composed of a battery core and a protection circuit board including various intelligent control chips. The cell of the mobile power source is mainly a high-capacity polymer lithium ion battery or a liquid lithium ion battery. The lithium ion battery has high voltage, high energy density, relatively light weight and mature production process. But because of the high energy density, it is very important to use it correctly, otherwise there may be some danger. Therefore, the batteries produced by regular manufacturers have perfect protection schemes, and have strict control on the charging and discharging circuits of the batteries. The protection circuit is designed for rechargeable batteries such as lithium-ion and lithium-ion polymers. It mainly provides over-charging, over-discharging and over-current protection. In addition, some circuits provide protection from the protection state, and some also Provides the function of charging 0V battery, which depends on the design capability and technical strength of the manufacturer. The protection IC in the protection circuit integrates a high-precision voltage detection circuit and a delay circuit, which can accurately collect the subtle changes of the loop voltage and control the on-off according to the length of the delay, thereby protecting the battery and the charged device. effect.
In theory, mobile power is relatively mature, and products of different brands are only slightly inconsistent in details. But this is only for regular manufacturers of battery products. It is necessary to fully apply and embody the technical maturity into the product, that is, the production of high-quality products depends on many factors such as technicians, manufacturing equipment, production process, process control, product testing system, etc., from raw materials to finished products. The completion of the products one by one, the more attention is paid to the products produced by the regular manufacturers of each production detail, the more the product can be added to the safety and reliability of the products. Relatively speaking, those manufacturers who are not formal or have low production capacity usually use the media or packaging to render mature technology or unique technology in the market. This is just a piece of paper, and it is completely irresponsible to customers and consumers. The key to the security of mobile power usage is how to choose a trusted product in the market before purchasing.
How to prevent mobile power explosion
1 Avoid placing the mobile power source in a place with high ambient temperature, such as summer exposure and closed compartments, near high heat sources such as ovens;
2 In daily use, avoid lithium. The positive and negative electrodes of the lithium battery should be in contact with metal. If it needs to be stored separately, use a battery case that is safe and reliable and has excellent insulation.
3 Lithium battery mobile power needs to be used frequently to achieve the best life. When it needs to be placed for a long time, it should be charged to the specified power and stored in the corresponding temperature environment (you can search for it yourself).
4 If the charging treasure has been shown as fully charged, the power should be unplugged.
5 When the mobile power lithium battery is damaged or the power is obviously reduced, it should be sent to the designated recycling station for recycling, and it should not be discarded at will. In fact, the maintenance of mobile power is very easy, you just need to remember that mobile power is afraid of heat, fear of impact, fear of water, to avoid all these situations appear OK.
Mobile power inferior battery safety hazard
Mobile power, mobile power, mobile phone, friends who are concerned about news, or you may encounter an event of explosion of mobile power. This has brought a lot of negative image to the mobile power industry market. The reason why mobile power will explode is because some cottage mobile power manufacturers use inferior batteries, and it is more likely to use recycled second-hand batteries.
Emerging mobile power explosive products
The reason why mobile power is so hot, the first is because it is in the development stage, in line with user needs, so there is a market. Second, the gross margin of mobile power that turned out to be close to 50%, so it will cause today's seemingly hot scene. This has also stimulated the army of the cottage, and in the short period of time there have been a large number of products of varying quality. It is precisely because of the opacity of the mobile power market, coupled with the extremely low cost of the cottage, so that they have the explosive mobile power products.
Security mobile power supply
The cottage brand is limited by its own strength and research and development costs. The mobile power source it produces uses low-cost, low-quality batteries, and the workmanship is poor and hidden. These inferior mobile power sources, hope that parasitic in the current hot mobile power environment, to seize the market at low prices to seek profit. If these inferior mobile power flows to the market and flow to the consumer group, then the smart phones and electronic products, and even personal safety issues will not be guaranteed.
What kind of batteries are easy to make mobile power "grenade"?
Turning on the previous battery explosion news, you will find that the quality of the battery is often the most direct cause of the event. So what kind of batteries are easy to make mobile power "grenade". Although the structure of the mobile power supply is simple, the conditions for the actual manufacturing are very high. Without professional factories and professional technologies, the standard requirements are not met. If there is no rigorous production process, there is no board and shell material that meets the requirements, and even the core of the mobile power source is also a "cottage". Such mobile power security risks are extremely terrifying, and it is very easy to become a stealth grenade.
Most of the cottage mobile power supplies are second-hand used, refurbished batteries or tractor batteries. These batteries have one characteristic, that is, the safety hazard is extremely great.
Summary: The circuit protection board of these inferior batteries is also unqualified, which not only has a short service life, but also seriously threatens the equipment and personal safety. Therefore, friends who go to the mall to buy mobile power mobile phones must polish your eyes.
