Method 1 to prevent accelerated aging of batteries: Do not use at high temperatures A lithium-ion battery with a 40% charge can be stored for ten years in the refrigerator, but a laptop that is plugged in and used continuously under this heating condition usually only lasts...

Recently, I saw an article about a netizen violently cracking the entire process of Tesla ModelS batteries. Today, I will explain it to everyone. First of all, let me tell you that Tesla batteries are not magical at all, because the batteries they use are actually well-known lithium-ion batter...

The spontaneous combustion caused by system short-circuit is related to the aging and lifespan of power lithium batteries. In order to isolate the battery pack from external rainwater, the airtightness of the power lithium battery assembly is usually high, and generally it must pass the IP67 s...

Regarding automobiles, the main cause of spontaneous combustion of power lithium batteries is thermal runaway, and the most common causes of thermal runaway include severe collisions, system short circuits, etc. First of all, let's talk about the first point, the combust...

matters needing attention In lithium-ion battery packs, there are differences between monomers. For example, the difference in capacity never disappears, but tends to worsen. Flowing the same current, relatively speaking, larger capacity tends to experience shallow charging...

As the name suggests, a battery pack is a combination of several batteries put together for power supply. The patchwork method includes the commonly heard series and parallel connections in circuit systems. Generally speaking, our lithium-ion battery packs are all parallel connected, and each...

Under the multi-level protection mechanism, even in the event of an abnormality in the power charger or laptop, the laptop battery can only transition to an automatic protection state. If the situation is not serious, it often works normally after re plugging and unplugging, without explosion....

In addition, the use of lithium manganese oxide material can significantly reduce costs. To improve the performance of existing safety control technologies, the first step is to improve the safety performance of lithium-ion battery cells, which is particularly important for...

Lithium ion batteries: In order to prevent over discharge or overcharging caused by improper use, a triple protection mechanism is installed inside a single lithium-ion battery. One is the use of switching elements. When the temperature inside the battery rises, its resistance increases accord...

In addition to the time-honored Tesla, Porsche and domestic hybrid models such as JAC, Zhongtai, Chang'an, and GAC have also joined the research and development force of 18650 batteries. Industry insiders say that in the future, more car models will fall in love with 18650 batteries, which...
