On October 7, Samsung's upcoming Galaxy S25 series is expected to be the company's first phone to use a 3nm chip. Earlier rumors said that Samsung will use the 3nm Exynos 2500 in the Galaxy S25 and Galaxy S25 +, and the 3nm Snapdragon 8 Elite in the Galaxy S25 Ultra. However, the latest report said that this plan ma
Now the U.S. House of Representatives Energy and Commerce Committee has passed the AM Radio for Every Vehicle Act of 2024, which requires automakers to retain AM (amplitude modulation radio) functions in vehicles manufactured and sold in the United States. Under the new bill, the National Highway Traffic
The adaptive pulse code modulation method changes the digital quantity according to the conversion rate of the voice analog signal, that is, in the pulse code modulation method, the quantization amplitude is changed accordingly. Generally speaking, the sound quality of the synthesized voice by the adaptive pulse cod
The basic control of the motor has three locks, namely self-locking, interlocking and interlocking. These three locks play a vital role in the entire process of motor control. It is necessary to understand their logical relationship in circuit control and the difference between the two. 1. Self-locking

The battery management system is a core component of electric vehicles, mainly realizing three core functions: prediction and calculation of battery charge and discharge status (i.e. SOC), balanced management of single cells, and battery health status logging and diagnosis. The functional block diagram is as follows
Recently, Huawei's new model Mate60 Pro has set off a sensation in the mobile phone circle. This flagship smartphone, which integrates multiple innovative technologies, once again proves the strength of Huawei's technology. When such powerful technical strength is integrated with smart electric vehicles, what kind o
Design requirements that a perfect PLC program must meet A complete PLC program is not as simple as just making the system run. It also requires complete annotations, sophisticated architecture, good scalability, a complete alarm protection system, and a pre-operation simulation system. Simplicity
Electric vehicles are a promising global strategy for achieving zero-emission transport. Tighter emissions standards and improvements in batteries (lower cost and longer range) are helping their growth. The three electrics are key components of the electric vehicle power system. Based on the concept of su
introduction: 汽车行业在“新四化”目标的牵引下快速发展，汽车电动化与智能化取得了显著的成果。汽车智能化的发展对汽车底盘提出了新的需求，传统汽车底盘在响应速度、执行精度、安全性等方面不再能满足智能汽车的要求，汽车底盘由传统底盘向线控底盘过渡。其中，线控转向（Steering-by-Wire，SBW）是线控底盘中控制横向运动的核心部件，是实现高阶自动驾驶的重要执行机构。国务院印发的《新能源汽车产业发展规划(2021-2035)》中将纯电动汽车底盘一体化、线控执行系统等列为重点技术攻关工程。国标《GB17675-2021 汽车转向系基本要求》中删除了不得装用全动力转向机构的要求(1999年的3.3)，法规层面
Why does the motor use a rectifier bridge? The main purpose of using a rectifier bridge in a motor is to convert AC power into DC power so that it can drive the motor efficiently. Here are a few reasons why motors use bridge rectifiers: 1. Motor type: Some types of motors, such as DC motors or
