Industrial grade lithium batteries reduce the operating costs of remote wireless sensors. Sol Jacobs, Tadiran Batteries At the heart of the IIoT are lithium battery-operated remote wireless devices that bring digital connectivity to emerging and evolving technologies such as SCADA, process control, industrial robotics, asset tracking, safety systems, environmental monitoring, M2M, AI, and wireless mesh […]
Gallery: Sights and sounds at the Battery Show North America 2022
Billed as the most comprehensive battery manufacturing event, the Battery Show combined with the Electric & Hybrid Vehicle Technology Expo in Novi, Mich., featured over 750 exhibitors and 150 conference presenters, with crowded aisles playing host to over 10,000 attendees. Here are a few of the sights that caught our eye while checking out the […]
Insights into a hidden flaw could unlock better batteries for EVs
A research team comprised of Princeton, Vanderbilt, and Argonne and Oak Ridge National Labs researchers claims to have uncovered a hidden flaw behind failures in solid-state batteries. In a solid-state battery, ions move through the battery within a solid material, in contrast to traditional lithium-ion batteries, in which ions move in a liquid. Solid-state cells…
Improved estimation of automotive radar signal strength
The signal strength of automotive radar can be estimated from the target radar cross section and distance. Greg Lee, Keysight Technologies Sir Robert Watson-Watt is generally credited as radar’s inventor, having developed the first practical system in 1935 and later applying radar to aircraft and weather. We’ve since used radar to monitor everything from ballistic […]
Evolving radar technology in ADAS
Lidar may become unnecessary for future autonomous vehicles thanks to advances in highly integrated RF chips. Prajakta Desai, Texas Instruments Over the years, the application of radar within the automotive industry has improved both safety and convenience. Radar can work in extreme environmental conditions such as rain, snow, dust and bright sunlight and also provide […]
Keeping autonomous vehicles on track
What autonomous vehicle developers need to know about inertial navigation systems. James Fennelly, Acienna inertial measurement systems The inertial navigation system (INS) is essential to autonomous vehicles. It provides timing information for sensor synchronization and rapid updates of velocity, position, and attitude needed for the ADAS (advanced driver assistance systems). It complements perception sensors for […]
Planning for vehicle dynamics with simulation
Vehicle dynamics play an important role in validating intelligent systems. Michael Peperhowe, dSpace gmbh Advanced driver assistance systems and autonomous driving (ADAS/AD) functions are designed to make everyone on the road more safe. Design engineers have long validated these functions by simulating them in test scenarios involving other vehicles, pedestrians, and obstacles. But it is […]
Design tips for high-voltage protection in EVs and hybrids
The primary goal of EV protective circuits: Keep vehicle occupants safe day-to-day and first-responders protected if the worst happens. Michael Zimmerman, Littelfuse, Inc. The 12-V automotive battery may become a relic of the past as electric vehicles (EV) and hybrid cars gain market share. EVs and hybrid vehicles use battery packs of at least 500-V […]
Hybrid sensors for connected vehicles
The dependence of smart vehicle features on sensing technology has manufacturers thinking about how to field devices that combine functions in economical ways. Estimates are that today’s vehicles can have between 60 and 100 sensors onboard. And over the next decade the number of sensors is expected to double. No wonder, then, there are efforts […]
The basics of dielectric resonator antennas
The mmWave equipment on connected vehicles may sport dielectric resonator antennas that look nothing like conventional antennas. Automotive designers have always put a premium on technologies that are light-weight and compact. The preference hasn’t changed for connected vehicles. As connected features increasingly rely on mmWave frequencies, designers investigate ways of shrinking the size of radio […]
