The length of battery life depends on two reasons. The first is that there are quality problems in itself, resulting in reduced performance and short usage; the second is that car owners usually do not know how to take care of the battery and wear out the battery. How should batteries be used to maximize their use and extend their lifespan? Kuai Kian Momentum has compiled 12 relevant experiences: 1. Resolutely do not use inferior chargers, and resolutely do not use chargers with mismatched models. The charger te

The so-called battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary. It uses a lead-based grid filled with sponge lead (also called a grid) as the negative electrode, a lead-based grid filled with lead dioxide as the positive electrode, and dilute sulfuric acid with a density of 1.26--1.33g/mlg/ml as the electrolyte. When the battery is discharging, metallic lead is the negative electrode and undergoes an oxidation reaction to produce lead sulfate; lead dioxi

In the field of lithium-ion batteries, due to the uncertainty of the impact of various parameters on battery performance, experimental design has a certain degree of blindness. The traditional exhaustive method to determine parameters has the disadvantages of heavy tasks, low efficiency, and is difficult to solve theoretical problems. With the development of simulation technology, simulation technology has been applied to the research and development of more and more scientific research fields. As a complementar

Battery balancing technology can improve the service life of the battery pack and extend the use time of the battery pack. It is suitable for large-capacity nickel metal hydride, 2V lead-acid batteries, lithium-ion batteries, 6V lead-acid, 12V lead-acid and other battery packs, as well as supercapacitor packs. Ladder batteries and selection Ladder batteries refer to batteries that have been used and have reached their original design life, and their capacity has been fully or partially restored through other

The quality indicators for evaluating switching power supplies should be based on safety and reliability as the first principles. Under the premise that the electrical technical indicators meet the requirements for normal use, in order to make the power supply operate safely and reliably in harsh environments and sudden failures, it is necessary to design a variety of protection circuits, such as soft start to prevent surges, prevent overvoltage, and undervoltage. voltage, overheating, overcurrent, short circuit, a

According to incomplete statistics from reporters, a total of 13 listed companies have invested a total of 43.5 billion in power batteries. Among them, BYD's 15 billion yuan investment in lithium battery expansion projects and the development of pure electric special vehicles is the largest, followed by Wulong Electric Vehicles' 9.3 billion investment in power battery projects. Jian Liang, an analyst at CCID Consulting's Automotive Industry Research Center, said in an interview with reporters that si

The improvement of energy density and lightweight of lithium batteries are the keys to future demand expansion. Especially in recent years, the market for "gadgets" for ordinary consumers that can perform multitasking has expanded, which has increased the demand for lithium batteries with high energy density and small weight. Industry analysts point out that in addition to traditional main applications such as laptops and mobile phones, new applications such as electric hardware tools, other consumer e

The Power Lithium Battery Engineering Laboratory of Ningbo Institute of Materials has carried out research on aluminum-ion batteries using graphene as electrodes. The recent research work was published online in "Advanced Energy Materials" under the title Large-sized few-layer graphene enable sa ultrafast and long-life aluminum-ion battery. Electrochemical energy storage technology is the key to solving the problem of integrating electric vehicles and renewable energy into the grid for power generation

The development of the new energy vehicle industry will bring positive impetus to the power battery market. Power batteries are still an emerging industry, and the high cost of battery systems is the main reason for the high price of electric vehicles. In hybrid vehicles, pure electric vehicles, and plug-in hybrid vehicles, the electric drive system is the main part of the value of new energy vehicles, and its value is more than half of the total vehicle cost; while the cost of the power battery in the electric dri
