With its excellent performance, lithium-ion batteries have become an ideal power source for a new generation of electric bicycles. It is best to charge the lithium battery of an electric bicycle according to the specification, or to calculate the capacity of the lithium battery and the current of the charger. What are the specific precautions for charging an electric bicycle with a lithium battery? 1. Lithium batteries of electric bicycles are generally charged, preferably according to the specification. If not, it depends on the capacity of the lithium battery and the current of the charger. For example, a 48V/20A lithium battery, a charger If it is a 5A charger, it will take a little more than 4 hours to charge it. If it is a 10A charger, it will take a little more than two hours. If it is a 20A charger, it will take an hour to charge it. 2. Generally, the newly purchased electric bicycle lithium battery is new and has a large capacity. The charging time will be long...

Last year, Xiaomi announced 200W power fast charging technology, and it only takes 8 minutes to fully charge a 4000mAh battery. The fact is that not only in the field of mobile phones, but also in the field of power batteries , fast charging is also one of the important directions of market attention. Generally speaking, most electric vehicles use ordinary charging technology. This ordinary charging method takes 8-10 hours to charge the electric car, while fast charging is fast charging. It only takes 1 hour to fully charge the battery. . To simplify the concept, in fact, fast charging uses high-current and high-power direct current to charge the battery. The real principle is that in the fast charging state, the lithium ions in the lithium battery move at high speed and are instantly embedded in the two poles of the battery. The method of realization is, first, use a wide charging pulse to charge the battery to increase the terminal voltage of the lithium battery . When the...

LCO batteries are a branch of lithium-ion batteries. In addition, there are lithium manganese oxide batteries, ternary lithium batteries , and lithium iron phosphate batteries. Compared with other types of lithium-ion batteries, LCO batteries are the most capable of charging Battery. LCO batteries have a stable structure, high specific capacity, and outstanding comprehensive performance, but their safety is poor and their cost is very high. The said voltage is 3.7V. First, Characteristics of LCO battery 1. Excellent electrochemical performance 2. Excellent processing performance 3. The tap density is high, which helps to increase the volume specific capacity of the battery 4. Stable product performance and good consistency Second, the parameters of LCO battery Standard discharge continuous current: 0.2C Maximum continuous discharge current: 0.5C Working temperature: Charging: 0~45℃ Discharge: -20~60℃ Product size: MAX 15*29*51mm Finished internal resistance: ≤180mΩ Lead type: na...

Compared with traditional mobile phones, smart phones are updated faster, with more and more functions such as high-definition large screens, high-pixel cameras, face recognition, etc., and the promotion and application of 4G, coupled with the improvement of people's disposable income, the shipment of smart phones continues to grow. According to statistics from Statista, global smartphone shipments increased from 305 million units in 2010 to 1.473 billion units in 2016. With the continuous increase in the penetration rate of smartphones, the significant improvement in the overall performance of smartphones has made the replacement cycle continue to extend. After 2017, the global smartphone has entered a stage of steady development. In the future, the development of technologies such as 5G will accelerate the replacement speed of smartphone products and enhance the replacement demand of downstream consumer terminals. At the 2019 Mobile World Congress, domestic mobile...

The tab is a raw material for lithium-ion polymer battery products. For example, mobile phone batteries, Bluetooth batteries, laptop batteries, etc. used in our lives all need to use tabs. The battery is divided into positive and negative poles, and the pole ear is the metal conductor that leads the positive and negative poles from the battery core. In layman's terms, the ears of the positive and negative poles of the battery are the contact points during charging and discharging. This contact point is not the copper sheet we see on the outside of the battery, but a connection inside the battery. The battery tabs are divided into three materials. The positive electrode of the battery is made of aluminum (Al) material, the negative electrode is made of nickel (Ni) material, and the negative electrode is also made of nickel-plated copper (Ni—Cu) material. They are all composited by film and metal tape. made. The film is the insulating part on the tab. Its function is...
