The principle of fuel power lithium battery is an electrochemical device that is the same as that of general batteries. Its single battery is composed of two positive and negative electrodes (negative poles, fuel electrodes and positive electrodes, oxidant electrodes) and electrolytes. The difference is that the active substances of general batteries are inside the battery, so the battery capacity is limited. The positive and negative electrodes of fuel power lithium batteries do not contain active substances, but

1. Lithium ion battery cannot be charged The electric vehicle lithium -ion battery does not enter the electricity. There are several reasons: the charger is connected to the back or the charger fails; the protective board protector does not restore or the protective board failure; Find the above problems in order: whether the charger is connected, whether the battery pack charging the positive and negative electrode plug is connected; the re -use electrical appliances to relieve the protective board protectio

Introduction to the technology of lithium -ion battery pack PACK automation production equipment. As we all know, from the entire process from the lithium -ion battery single battery cell to the automation module to the PACK production line, the degree of automation of the assembly line is an important factor that determines the quality and production efficiency of the product. Lithium -ion battery manufacturing equipment is generally three types: front -end equipment, middle -end equipment, and back -end equipment

Comparison of the performance of lithium -ion batteries and batteries Temperature tolerance: The working temperature of the common lithium-ion battery is -20-60 degrees Celsius, but generally the performance of lithium-ion battery after 0 ℃ will decrease, and the discharge capacity will be reduced accordingly. , Commonly 0 ~ 40 ° C. The temperature of the lithium -ion battery with special environment requirements is different, and some can even run normally in the environment of hundreds of degrees Celsius.(

What is the lithium ion battery pulse charging? What does pulse charging affect lithium ion batteries? The charging time and life of lithium -ion batteries have always been the bottleneck of electric vehicle applications. Traditional fast charging technology may shorten the cycle life of lithium -ion batteries. The polarization voltage is the external manifestation of the charging current in the electrochemical reaction effect of the battery. During the charging process, the polarization voltage will shorten the li

Detailed explanation of the characteristics of mobile assembly portable lithium -ion battery UPS power supply system. With the increasing degree of dependence on various electronic equipment, the computer rooms in many important places must supply temporary UPS power supply to ensure power supply. The UPS power supply system of mobile assembly lithium -ion battery The load capacity and maximum load power can be expanded arbitrarily. Detailed explanation of the characteristics of mobile assembly portable lithium

Uninterrupted power manufacturers tell you the difference between UPS power bids and long machines. UPS uninterrupted power supply is generally divided into long machines and bid machines. Long machines must be external battery packs (with a battery cabinet), and the standard machine must have a battery inside the machine. From practical and battery life, of course, long aircraft are better. Here, the uninterrupted power supply UPS manufacturer will tell you the difference between the long machine and the benchmark

What are the disadvantages of dual -machine redundant improvement of the reliability of the UPS power system? Dual -machine redundant means backup. One machine has problems, and the top of the other machine is to improve the reliability of the UPS power system. Usually two or more stand -alone single machines are used to form a dual or multi -machine UPS system, which improves the reliability of power supply power, so that the UPS interrupt power supply will not occur while the single UPS fails. What are the dis

Lithium -ion battery production process, lithium -ion battery PACK production line. Objectively speaking, the production process of lithium -ion battery production process is divided into three major sections, one is polar production, the other is the production of batteries, and the third is battery assembly. The production process of lithium -ion batteries is not consistent with each manufacturer. Each link in the lithium -ion battery production line must be strictly managed and carefully managed, so as to improv
