Advancing Electric Vehicle Battery Characterization By Integrating Drive Cycle On Cooling Impacts


Battery powered electric vehicles (EVs) and hybrid electric vehicles (HEVs) have been gaining market share as the public’s environmental concerns drive the demand for better fuel efficiency. Apart from the need to improve the mileage one can drive before recharging, battery reliability is another major concern. Effective cooling in intense charge/discharge conditions is crucial to minimizi... » read more

Silicon-based Power Semis Face Challenges


Suppliers of power semiconductors continue to develop and ship devices based on traditional silicon technology, but silicon is nearing its limits and faces increased competition from technologies like GaN and SiC. In response, the industry is finding ways to extend traditional silicon-based power devices. Chipmakers are eking out more performance and prolonging the technology, at least in th... » read more

New Ways To Improve Batteries


Researchers around the world are racing to develop more efficient, denser, and safer battery technology, and they are reaching far beyond where research has gone before. Much of this is being driven by concern over exhaust from internal combustion engines, which are responsible for a significant portion of global CO2 emissions. Nearly all carmakers today have announced plans to develop batte... » read more

Safe And Reliable MOSFET Operation In Bidirectional Power Switch (BDPS) Applications


The global market for battery-powered applications is rapidly growing, including power tools, service robots, light electric vehicles, and many others. The evolution of switched-mode power supply (SMPS) topologies enables designers to ensure safe charging and discharging of the equipment’s battery using bidirectional converters through the same terminal. However, to meet the safety requiremen... » read more

Making Batteries Denser And Safer


Battery technology is improving swiftly, driven by the rapidly rising demand for electric vehicles and the vast body of knowledge developed by the semiconductor industry. The market for electric vehicles (EVs) is on a fast upward trajectory, with global sales predicted to grow more than 12 times to more than 31 million vehicles. In fact, EVs will account for almost a third of new vehicle sal... » read more

The Silicon Carbide Race Begins


The growing adoption of silicon carbide (SiC) for a variety of automotive chips has reached the tipping point where most chipmakers now consider it a relatively safe bet, setting off a scramble to stake a claim and push this wide-bandgap technology into the mainstream. SiC holds great promise for a number of automotive applications, particularly for battery electric vehicles. It can extend d... » read more

Auto Outlook: Down But Not Out


For years, automotive has been an engine of growth in the semiconductor industry, although the market is expected to decline in 2020. Several types of chips are used in automobiles, such as analog, memory, microcontrollers, processors and RF. But the automotive IC business still represents a small percentage of the overall semiconductor market. It pales in comparison to the smartphone chip m... » read more

Week In Review: IoT, Automotive & Security


Internet of Things Qorvo, the company whose products sent pictures back from Pluto and Arrokoth (formerly Ultima Thule) on New Horizons, is showing off a couple smart home, IoT products at CES 2020 in Las Vegas next week. The company says its new transceiver chip QPG7015M will simplify gateway IoT design because the chip can simultaneously handle all open, smart home protocols, including ZigBe... » read more

Replenishing The Grid With A SiC-Based Bi-Directional On-Board Charger


Range anxiety and charger availability have long been the main hurdles to the adoption of electric vehicles. But even as car makers have demonstrated their batteries can go longer distances and charging stations have proliferated, challenges with EV charging remain as well as opportunities to load balance power grids. The migration to electric vehicles also means looking at how they can bett... » read more

Betting On Hydrogen-Powered Cars


The automotive industry is taking another look at hydrogen fuel cells, but how they ultimately fare depends on a combination of consumer demand, automaker investment and infrastructure build-out. Hydrogen fuel cell technology has been steadily advancing over the past six decades since the first practical fuel cell system was demonstrated by Cambridge engineering professor Francis Bacon. The ... » read more
