New Energy Vehicle Ethernet Protection

With the rapid advancement of new energy vehicle technology, traditional industrial Ethernet technology is also being widely used in the automotive industry. Automotive Ethernet provides the automotive industry with topology flexibility, high bandwidth, and anti-interference communication, making it an inevitable trend for the development of intelligent connected vehicles. In 2016, the IEEE standardized the automotive Ethernet system 100BASE-T1 and 1000BASE-T1 developed by the Ethernet Alliance Committee to meet specific requirements of automotive applications, especially in terms of electromagnetic interference (EMI) and electromagnetic compatibility (EMC).

TOLL (Transistor Outline Leadless) packaged MOSFETs have been widely used in terminal applications such as electric bicycles, electric motorcycles, lithium battery protection, and communication power supplies due to their compact size, low package resistance, low parasitic inductance, and low thermal resistance characteristics. TOLL (Transistor Outline Leadless) package is an advanced power device packaging technology with multiple notable features and advantages. The following is a detailed analysis of the TOLL package: I. Basic Features

 1. Introduction






"Automotive-grade" refers to specification standards that meet the specific requirements of the automotive industry for electronic components. These standards ensure that automotive electronic control systems can operate stably and reliably in complex and variable operating environments. In the automotive industry, the importance of automotive-grade components is self-evident, as they are directly related to vehicle performance, safety, and passenger driving experience. Due to the complex and variable operating environments of automobiles, such as extreme conditions like high temperature, low temperature, high humidity, vibration, etc.,

Electric Vehicle Battery Management System
The Battery Management System (BMS) of electric vehicles is a key component used in electric vehicles to monitor and manage battery system performance. It helps balance battery charge, prevent overcharging and over-discharging, thereby ensuring the safe, reliable, and efficient operation of lithium-ion batteries, while optimizing the overall efficiency and lifespan of the battery.

Under the trend of automotive intelligence and electrification, the automotive-grade chip market shows huge growth potential. Currently, the entire automotive chip market has high requirements in safety, reliability, etc., but most chips in the automotive market are monopolized by foreign manufacturers. China is currently in a state of insufficient domestic substitution, low self-sufficiency rate, etc., urgently needing accelerated breakthroughs.
Chips can be divided into consumer chips, industrial chips, automotive chips, and military chips according to application scenarios.
Automotive chips, i.e., "automotive-grade chips", refer to integrated circuits that meet automotive quality management systems, reliability, and functional safety requirements. Automotive...

1. What is IGBT? IGBT stands for "Insulated Gate Bipolar Transistor". It is a composite device composed of MOSFET and bipolar transistors, combining the advantages of both types of power transistors. IGBTs come in two types: N-channel and P-channel, with N-channel being the mainstream product currently. The following Figure 1 shows an N-channel I

Electronic components in circuits mainly include diodes, transistors, thyristors, and field-effect transistors, among which diodes and transistors are the most commonly used. Correctly determining the quality of diodes and transistors is one of the basic skills electricians should master. 1. Measurement of Diodes 1. Usually, use the Rx100Ω range or Rx1kΩ range of a multimeter to measure diodes with lower withstand voltage and smaller current. 2. When measuring the forward and reverse resistance of a 2AP9 type diode with a multimeter's resistance range, the Rx100Ω range should be selected. If the forward resistance value of the diode is between tens to hundreds of ohms, and the reverse...

"Cloud computing" (cloud computing) is believed to be known to everyone. Simply put, it involves placing resources on a virtual network cloud, and users can access and use them via the internet.

So what is edge computing? How does it differ from cloud computing?
First, let's look at Forbes' predictions for "edge computing" trends in 2024:
