The secret to extending the life of lithium-ion batteries is gone in a hurry Recently, Fujitsu Electric Vehicles and bik, a well-known domestic battery brand, held a conference on lithium-ion battery electric vehicle technology exchanges. Why are lithium-ion batteries better than lead-acid batteries? How to prolong the service life of lithium-ion batteries? Dr. Mao Huanyu, general manager of bik batteries, explained the working principle and usage skills of lithium-ion batteries on the spot, and answered ques

1. It is necessary to take a balanced situation: in the case of battery production, the completion of the storage time is longer, because of the different various static power protection boards and various battery self-discharge rates, the formation of the entire bundle, the battery voltage, has a significant voltage difference , but the same guarantee ability, the function of balancing the voltage of the battery pack under the condition of balance, can realize the effect of fully charged and fully discharged batte

Analysis of single lithium-ion battery technology The basic design of the lithium-ion battery remains the same as in Sony's 1989 patent application. The single unit shapes are cylindrical, square metal casing (aluminum/steel) and square soft case. The square battery has a large capacity and is generally composed of windings, z-shaped laminations, windings + laminations, positive cladding, laminations + laminations. Lithium Ion Battery Cylindrical battery technology is the most mature, and the manufactu

Important technical requirements for lithium iron phosphate batteries (1) Operating temperature range The battery is used at the following ambient temperatures: Charging environment temperature: 10℃~55℃; Discharge ambient temperature: 20℃~60℃. (2) Electrical properties The performance of the cells within the battery module is consistent. All batteries in a battery module are products of the same manufacturer, have the same structure and chemical composition, and should meet the following requir

General process of lithium-ion battery manufacturing The basic principle of lithium battery is redox reaction. The chemical properties of lithium metal are very active, which makes the processing, storage, use, and manufacturing process of lithium metal quite strict and complicated.(Lithium - Ion Battery Equipment) 1. Pulping: Mix positive and negative active substances with special solvent and rubber powder, stir evenly at high speed, and make pulp into positive and negative substances; 2. Coating: The sl

With the two-year fire of lithium-ion batteries and new energy vehicles, and the recent small disaster in the stock market, the lithium-ion battery sector has gradually climbed out of the quagmire and has attracted the attention of the market. As new energy vehicles are relatively complex, there are many standards, and prices are classified and compared in detail, the author, as a former electronics and electrical professional technician, makes our knowledge simple and effective in terms of lithium-ion batteries, w

Lithium-ion battery BMS has discharge overcurrent and short circuit protection functions, with an overcurrent current of 3A and a delay of 0.2s. 1. Determine overcurrent and discharge conditions When the smart battery is in the state of charge and discharge, the detected current exceeds 3A, and it is still greater than 3A after 0.2s delay, then it is judged as overcurrent. At this time, the protection executive circuit cuts off the discharge protection switch. To remove the protection condition is to connect

1. The working principle of lithium-ion battery As we all know, lithium-ion batteries use lithium cobalt oxide as the anode and carbon as the cathode. Lithium-ion batteries work by charging and discharging. When the battery is charged, lithium ions are formed at the positive electrode of the battery, and the lithium ions pass through the electrolyte to the negative electrode. Negative carbon has a layered structure with many micropores. Lithium ions reaching the negative electrode are embedded in the micropores

Electric bicycle lithium-ion battery charge balance function Lithium-ion batteries for electric bicycles have the function of charge balance, mainly because lithium-ion batteries have the advantages of small size, high energy density, no memory effect, long cycle life, and low self-discharge rate.(Lithium - Ion Battery Equipment) 1. The battery matching or the influence of the external environment causes the battery voltage of each battery to be different. 2. When the battery voltage difference between the
