On January 17, the National Bureau of Statistics released data showing that China's production in December 2023 was 41,980 sets, a year-on-year increase of 3.4%; the annual production in 2023 was 429,534 sets, a year-on-year decrease of 2.2%. After six consecutive months of year-on-year decline in production, t

　　 As a simple data sending protocol, the UART data sending protocol is widely used in the data transmission of various current digital peripherals. However, current PCs have the problem of no UART interface or fewer interfaces. When a PC needs to be used to handle multiple digital devices simultaneously, UART expansi

In the Battery Warring States Period, Honeycomb Energy showed its sword, "Who will compete with the "King of Hybrids"? "Enter the narrow door, see the glimmer of light, and take the long road" is the strategy proposed by Honeycomb Energy at the first Battery Day in 2019. On December 12, Honeycomb Energy held its fou

In 2014, the domestic new energy vehicle market was bleak. Some car companies were at the bottom, struggling for a long time, and some even faced bankruptcy. Many car companies have a wavering attitude towards new energy vehicles. GAC has previously launched two extended-range models, which encountered problems such

PLC Counter Application Find the counter operation in the basic instructions and click Add Count. The Q point of the counter is the output point, and the output is when the number of times is reached; the R point is the reset point; PV is the set value (number of times); CV is the current value

Since the relevant theories of motor NVH problems are complex and involve multiple disciplines such as electromagnetics/structures/acoustics, it is a typical multi-physics field coupling problem, and its simulation analysis is somewhat difficult. Ansys software can now well implement motor NVH simulation calculation

Problems faced in the analysis of intended functional safety At present, the industry mainly conducts the intended functional safety design test work in accordance with the process guidance of the international standard ISO 21448 for safety of intended functionality (SOTIF). The main method given for its quanti

Recently, Apple obtained a new technology patent titled "Device, Method and Graphical User Interface for Synchronizing Two or More Screens", which allows users to synchronize their iPhone, iPad and Mac laptop screens with The vehicle and machine are synchronized. The acquisition of this patent will bring a new experie

In 2023, the new energy vehicle market is developing in full swing. As an important part of new energy vehicles, power batteries are also developing very rapidly at the technical level. As for which type of power battery can have the last laugh? It can only be said that times make heroes. There are things that should

Wound rotor motor is a type of asynchronous motor. Asynchronous motors are divided into wound rotor type and squirrel cage type according to the form of rotor winding. The working principle of wound rotor and squirrel cage motors is the same. The difference is that in the rotor of a squirrel cage mot

With the gradual improvement of automobile electrification and intelligence, the number of wiring harnesses is increasing. Although bus technology is widely used in modern automobiles, which further reduces the number of wires and connectors, streamlines the huge wiring harness system, and improves the lightweight l

On May 13, French media outlet Les Echos reported that solid-state battery manufacturer Huineng Technology plans to invest 5.2 billion euros (note: currently about 39.364 billion yuan) to build a new battery factory in Dunkirk, northern France. Huineng Technology signed a technical cooperation agreement with Merc

　　The functional principle of the digital megohmmeter is explained as follows: 　　Detailed description 　　1. Turn on the power switch of the megger, and the power indicator light on the switch should light up. 　　2. Start self-test, and operation prompts will appear on the LCD screen. 　　3. Press the voltage selection but

The concept of three-phase synchronous motor The three-phase synchronous motor is a type of AC rotating motor, named because its speed is always equal to the three-phase synchronous speed. The three-phase synchronous motor is mainly used as a generator, but can also be used as a motor and a phase regulator. In

There are two types of thyristors: one-way thyristors and two-way thyristors, both of which have three electrodes. One-way thyristor has cathode (K), anode (A), and control electrode (G). A two-way thyristor is equivalent to two single-phase thyristors connected in reverse parallel. That is, one of the unidirectional
