While the solid-state battery industry is still engaged in a long technological marathon for the "ultimate solution" for electric vehicles , some companies have begun looking for mor...[Details]

Some time ago, I attended the 4th Energy Chemistry Forum of the Chinese Chemical Society and learned about high-energy-density and high-safety batteries. I would like to summarize and share this wi...[Details]

Electric motors and internal combustion engines of the same power have similar torque levels. High power requires high torque, and torque determines a vehicle's acceleration speed, commonly known a...[Details]

1 Introduction In the mid-1960s, American scientist Maas conducted extensive experimental research on the charging process of open-cell batteries and proposed an acceptable charging curve for ...[Details]

Based on the commutation technology, thyristor rectifiers are classified into two main types. Line-commutated and force-commutated inverters are commonly used, while other commutated inverters, nam...[Details]

My career has been closely tied to the semiconductor industry. From product management to content marketing, I've provided countless forecasts and predictions across a variety of roles. Whethe...[Details]

The difference between a series inverter and a parallel inverter is that they use different oscillation circuits. A series inverter connects L, R, and C in series, while a parallel inverter connect...[Details]

With the advancement of science and technology and the promotion of green, energy-saving, and circular development, the demand for precise control and accurate measurement is increasing. In the pow...[Details]

From time to time, I see some audiophiles spending a lot of money or a lot of time to DIY speakers, but the results are not what they want. Below I list some of the small experiences I summarized b...[Details]

Lithium-ion batteries are a key component of electric vehicles. Their high energy density enables them to store a large amount of energy in a relatively compact and lightweight package, which is cr...[Details]

As the power density of modern electronic systems continues to increase, effective thermal management has become critical to ensuring system performance, reliability, and longevity—especially in hi...[Details]

As the core of electric vehicles, batteries are concerned with vehicle use and maintenance. The operation of vehicles is guaranteed by the electricity generated by batteries. For batteries, battery...[Details]

Today, the voltage of electronic products continues to rise to 400V, 600V and even 1000V, so there are few electronic load models that can handle such high voltages. Many people consider connecting...[Details]

With rapid economic development, the types of pollution sources are increasing, especially in chemical and industrial zones and their surroundings. The patterns of pollution and the types of ecolog...[Details]

While aberration theory is a vast subject, a basic understanding of some fundamental concepts can make it easier to understand: spherical aberration, astigmatism, field curvature, and chromatic abe...[Details]
