The main function of the battery management system (BMS) is to monitor cell voltage, battery pack voltage and battery pack current. In addition, given the high voltage design of the BMS, it is necessary to measure the insulation resistance between the high and low voltage domains to catch defects in the cell structure and prevent dangerous conditions from occurring.
BLDC motor is a rotary motor consisting of a three-phase armature winding on the stator and a permanent magnet on the rotor. The mechanical structure of the BLDC motor is opposite to that of the traditional permanent magnet brushed DC motor. The rotor is equipped with a permanent magnet and the stator is equipped with a motor winding. However, as the name suggests, BLDC motors have no brushes and require no regular maintenance or replacement, making them less susceptible to wear and tear
The power grid is designed to run on alternating current for a number of reasons, but almost every device needs direct current to operate. As a result, AC-DC power supplies are almost everywhere, and with increased environmental awareness and rising energy prices, the efficiency of such power supplies is essential to reduce operating costs and rational use of energy.
Traction inverters are the main component that consumes battery power in electric vehicles (EVs), with power levels up to 150kW or higher. The efficiency and performance of traction inverters directly affect the driving range of electric vehicles after a single charge. Therefore, in order to build the next generation of traction inverter systems, silicon carbide (SiC) field-effect transistors (FETs) are widely used in the industry to achieve higher reliability, efficiency and power density.
The artificial intelligence (AI) revolution has arrived. With the public release of applications such as ChatGPT, people are able to experience firsthand the power and potential of deep neural networks and machine learning (ML). ChatGPT is a language model that has been trained using massive amounts of text data from the Internet and books to generate text that resembles that written by real people.
With the growth of electric vehicles, the demand for small, precise position sensors in automotive applications will grow to $1.6 billion by 2026, tracking the position of rotors in motors responsible for traction machinery, power steering and Windows, and ensuring control and safety coverage.
