Sponsored by Heraeus Major trends in electronic applications involve operation temperatures above 150 °C, increased power density and longer lifetime. This requires a high melting temperature and fatigue resistance, improved thermal conductivity and reduced electrical resistivity of the connecting material. Silver-based sintering technology is suited for high operation temperatures due to its pure Ag die… Read more »

Colorado adopts California zero-emissions vehicle mandate
Colorado’s Air Quality Control Commission (AQCC) voted 8-1 to approve the state’s adoption of the zero-emissions vehicle mandate. Colorado became the 10th state to join California’s ZEV program. According to the state’s Air Pollution Control Division (yes, this is a separate agency from the AQCC), automakers will be required to make ZEVs 4.9% of the… Read more »
A closer look at current sensors in EVs
Pretty much every electronic circuit that handles significant power utilizes some means of measuring current, whether to simply protect against overload or because it is a basic functional requirement. In this article we’ll cover some of the more common devices and circuit techniques for measuring current in the major subsystems of an EV, including when… Read more »
Bosch developing cloud-based service to help prolong battery life
In an attempt to prolong EV battery life, Bosch is developing new cloud services that supplement individual vehicles’ battery-management systems. The company calls the new service Battery in the Cloud. Its first customer is DiDi, a gargantuan Chinese mobility provider, which is equipping a pilot vehicle fleet with Bosch battery services in the city of… Read more »
The development of EV battery testing
Sponsored by AVL High voltage batteries, a key component of electrified powertrains, play a critical role in future mobility concepts. Coupled with one or more electric drives, the integrated propulsion system determines driveability, package flexibility, and other brand-defining DNA. Similarly, the costs and robustness of a battery also contribute to the success of e-mobility. To… Read more »
Letter from Amsterdam: EVs of all shapes and sizes
The streets of Amsterdam are a chaotic carnival of transportation options: the famous flotilla of bicycles (which have dedicated lanes on all major streets) shares the cobblestones with skateboards, scooters (gas, electric and pedal), Segways, buses (diesel and electric) and street trams. There are also canal boats, an underground Metro system, and of course automobiles… Read more »
Learn how light-curable materials can improve EV system performance
Sponsored by Dymax The current movement toward vehicle electrification and the desire to put self-driving cars on the road is fueling an automotive revolution. Manufacturers are searching for assembly solutions that increase productivity and throughput, decrease rework and costs, and boost the bottom line. Concurrently, design engineers are striving to create better performing, more reliable… Read more »
SiC vs GaN semiconductors for EV power converters: Tech Opinion
Just as engineers are starting to get used to the advantages (and quirks) of silicon carbide (SiC ) devices, another semiconductor material joins the fray: gallium nitride, or GaN. Though there are some superficial similarities between these two materials, and even some overlap in their areas of best use, it is my opinion that only… Read more »
Kraft Heinz adopts electric terminal trucks at Ohio distribution center
Food company Kraft Heinz has replaced five diesel terminal trucks with EVs at its distribution centre in Groveport, Ohio. The Orange EV T-Series electric terminal trucks will be operated by Firefly Transportation Services. “This decision by Kraft Heinz demonstrates thoughtful mitigation of the extremely high operational, economic, and environmental costs of using diesel trucks,” said… Read more »
Battery bonding: Ultrasonic wire bonding vs laser welded bonding
Ultrasonic wire bonding vs laser welded bonding Li-ion cells come in many different shapes and size. There’s also a large variety of options to choose from when designing the connections between each cell and a vehicle’s electronics. In automotive applications, it’s critical to design reliable connections that are cost-effective and suited to high-volume manufacturing. F&K… Read more »
