How to correctly use and maintenance of mobile phone lithium battery?

Source: 2020 - 04 - 15 18:48 hits: once the correct use of cell phone lithium batteries today, in our daily life indispensable phones are almost all lithium-ion batteries, but not everyone knows how to correctly use and maintenance of lithium batteries, so how to correctly use and maintenance? Used in lithium batteries is one of the biggest myths to activate cells, and a lot of people still stay for 12 hours a day, the activation cell repeatedly charge three times of ancient myths is the cause of people's knowledge is still not fully buffer from a nickel battery times, this approach in nickel battery now is still a lot of people, or even a part of the business hall or in the mobile phone industry, are not really understand, at the time of customers to buy mobile phones will also gave them the wrong filling electricity again and again. Lithium battery and nickel batteries on the charging characteristics have very big distinction, if the form of nickel battery charging and discharging, great damage will inevitably brings to the lithium battery, especially liquid lithium battery, its damage is more serious. In rechargeable lithium batteries, therefore, must be in strict accordance with the manufacturer's instructions, professional operation of qualified operation, avoid damage to the battery quality and reduce the storage capacity of the battery, affect the use of mobile phones. In addition, don't need rechargeable battery lithium batteries has been staring at the full, when, after the expiration of the lithium battery will automatically stop charging, and there will be no nickel battery in ten hours non-stop charging, that is to say, no matter how long the battery charger when the battery is full of, charging Bai Zhuang after how long. Rapid detection of lithium battery self-discharge is still a problem with the intensification of global energy shortage, emerging in the new energy industry, has a good prospect of secondary battery technology has attracted much attention. Lithium-ion batteries, no pollution, high specific energy, long cycle life and other characteristics, widely used in various kinds of instruments and the electric car energy systems. And the presence of lithium battery self-discharge phenomenon not only causes the battery itself, the loss of energy, also causes the contradiction between the lithium battery self-discharge battery life decreases, rapid capacity attenuation, lead to the battery management system ( BMS) Prediction ( SOC) Battery charging a greater error, electrical fault, the control strategy of the electric car battery discharge system. However, there is no fast measuring technology of battery self-discharge. The battery self-discharge is refers to the battery in the condition of open circuit voltage drop, of reduced capacity, is one of the main parameters of battery performance. Self-discharge rate was 20% ~ 25% a month of nimh batteries, lithium ion battery self-discharge rate was 2% ~ 5% a month. Theoretically, the self-discharge of the battery can be zero, but in the practical application of the battery, because of the production process, self-discharge are impossible to erase. A large number of individual cell self-discharge often leads to its voltage drops rapidly, leading to the power battery charging capacity is weak. Therefore, detecting the self-discharge of the battery is particularly important. And process the self-discharge of the battery and battery materials and processes, along with the environmental temperature, battery life and charging status. But the existing measuring methods cannot be directly into the battery internal measurement, this brought difficulty to self-discharge detection. According to industry standards development method of long open shelf is to put the battery in high temperature or room temperature for 7 days or 28 days, through the battery discharge to cut-off voltage measurement to determine the discharge performance. This method need a month of shelves on the battery test, cycle is long, influence factors, precision co. , LTD. , take up a lot of equipment and site a long time, poor safety test, is a huge waste of manpower and financial resources. Because inside the battery self-discharge phenomenon, the existing measuring methods cannot be directly detected, which makes the self-discharge of the battery detection more difficult. According to the definition of self-discharge, can be done by long time use of open circuit detection of self-discharge.
