Synopsys, Inc. announced the expansion of its Virtualizer™ Development Kit (VDK) portfolio for Renesas’ RH850 MCU with the new RH850/E1x series reference virtual prototype, which targets powertrain electronic control units (ECUs).
The Synopsys VDK is a software development kit integrating Renesas’ RH850 MCU virtual prototypes with software debug and analysis tools to enable automotive engineers designing RH850/E1x-based ECUs to start software development and integration and test months before hardware is available, resulting in higher product quality and reduced development cost.
The AT549RBT cored-spring inductor from Coilcraft CPS (Critical Products & Services) features a temperature rating of -55°C to +300°C, making it suitable for extreme-temperature applications such as on-engine automotive.
The AT549RBT has an inductance value of 1.0 µH, a maximum current rating of 1.0 Amps and DC resistance of 15.0 mOhms. It can withstand a 40 second reflow at 350°C. It features nickel-clad copper terminations as standard, with other terminations available upon request.

The AS5162, paired with a simple two-pole magnet, accurately detects angular displacements as fine as 0.09° over a full revolution. Its non-contacting semiconductor technology is immune to stray magnetic fields and, unlike optical or contacting position sensors, it is unaffected by contaminants such as oil, grease or dirt.

AeroVironment, Inc. introduced TurboCord™, a compact, UL-listed, dual mode 240-volt/16-amperage and 120-volt portable charging cordset (MSRP $649) for EV charging. TurboCord is also available in a 240-volt only version (MSRP $599).
Wahid Nawabi, senior vice president and general manager of AeroVironment’s Efficient Energy Systems business segment, said TurboCord simplifies the charging process and can reduce costs significantly. It requires no charger installation, and includes safety features such as waterproofing for indoor and outdoor charging, all-environment operation and built-in thermal sensors for protection against faulty wiring or inadequate power.

A new Bosch start-stop system stops the engine when the vehicle is traveling at speed, helping to reduce fuel consumption by 10 percent.
Tests carried out by Bosch have shown that combustion engines runs needlessly about 30 percent of the time, meaning that the vehicle could simply coast for about a third of every journey.
Although these phases are not taken into account in the New European Driving Cycle (NEDC), under real traffic conditions the function will give drivers a roughly 10 percent fuel saving.

ON Semiconductor introduced two new AEC-Qualified ICs which, thanks to their wide input voltage range and extensive operational temperature range, are highly optimized for automotive powertrain and in-cabin deployment.
Running off a 2 volt (V) to 44 V input voltage, the NCV8876 non-synchronous boost controller with automatic wake up and shutdown functions is designed to supply a minimum output voltage during start-stop conditions in order to counteract any sag in the vehicle’s battery voltage.

The ASM Pneumatics model library, which will become part of the dSPACE Automotive Simulation Models (ASM) product family, enables realistic brake simulation for commercial vehicles, and comfort functions for passenger vehicles.
ASM Pneumatics is ideal for developing and testing electronic brake systems (EBS), air suspension electronic control units (ECUs), level control ECUs, etc. ASM Pneumatics adds a complete realistic pneumatics system to the models for passenger vehicles (ASM Vehicle Dynamics), trucks (ASM Truck) and trailers (ASM Trailer).
HELLA has signed a product evaluation contract with Nickel-Zinc (NiZn) battery developer PowerGenix and will conduct real-world vehicle tests to evaluate the ability of NiZN batteries to meet the high-power requirements of 48-volt mild hybrid systems, while also reducing overall system complexity and cost.
“Nickel-Zinc could offer some unique benefits in 48-volt systems,” said Dr. Marc Nalbach of HELLA. “It’s inherently very safe and also promises to provide equivalent emissions reductions, but at a lower cost. We believe our evaluation will open up a lower cost product to our OEM customers interested in reaching the fuel economy gains offered by 48-volt mild hybrid systems.”
The company said that functional enhancements to BOBCAT 2 were designed to make the system more powerful and flexible, offering many features found in higher-cost test solutions.
Functional enhancements include the ability to generate a report template within BOBCAT 2 that eliminates the need to export testing data. The user can instantly access the test data necessary to optimize the engine.

The firm described the AS8506 as “a vastly simplified and more robust method” of implementing cell monitoring and balancing in lithium battery systems.
The AS8506 performs distributed cell monitoring and balancing operations for stacked cell modules, including Safe Operating Area (SOA) checks and passive or active cell balancing.
