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

How can domestic private enterprises break through the technical barriers of lithium-ion battery materials? With the development of the global new energy vehicle industry is in accordance with the direction of power lithium-ion battery development, because it has a large energy density, small size, light weight, etc., and the industry is most concerned about the industry, but for some domestic companies lithium The development of ion batteries, the technical barriers for lithium-ion battery materials, and the full-

1. What is a lithium-ion battery Lithium-ion batteries are the batteries we use in mobile phones or electric vehicles. A more professional explanation is a rechargeable battery that uses metal lithium or lithium alloy as the positive electrode material and uses a non-hydrolyzed solution. Lithium-ion batteries can be roughly divided into two categories: lithium-ion batteries and lithium-metal batteries. We use a lot of lithium-ion batteries, and then we start to see that lithium-metal batteries are safer, m

Lithium battery explosion-proof circuit and explosion-proof cell technology Lithium-ion batteries have become the batteries of choice for portable electronic devices. Batteries, with their high capacity density and competitive prices, are expected to remain the mainstream of the market in the next few years. But lithium-ion batteries are always in danger of exploding. As applications rose, so did the explosion. In fact, with proper battery system design and battery level determination, Li-ion batteries are very

Due to the characteristics of the lithium-ion battery itself, it must be equipped with a protection board (PCM) or a battery management system (BMS) before it can be used. Lithium-ion batteries without protective plates or without a battery management system are strictly prohibited. Without a protective shield or battery management system, lithium-ion batteries can be a safety hazard and can even cause a fire or explosion. Safety always comes first when it comes to batteries and battery management systems.(Lithium

Design of lithium-ion battery switching power management system Lithium-ion battery is an emerging industry in the 21st century, and it has rapidly developed into a trend in recent years. Lithium-ion batteries have great advantages in the battery industry and are nationally recognized green energy. It is not only applicable to the consumer electronics market, but also to the field of new energy vehicles. Lithium-ion batteries are portable. For consumers, they want to get high-capacity power while reducing the we

Passive equalization and active equalization of lithium battery protection board Hefei lithium-ion battery protection panel commonly used equalizing charging technologies include constant shunt resistance equalizing charging, switch parallel resistance equalizing charging, average battery voltage equalizing charging, switched capacitor equalizing charging, buck converter equalizing charging, inductor equalizing charging, etc. When lithium-ion batteries are charged in series, each battery should be charged evenly
