EV Engineering

By Osamah Ahmad, product marketing, C2000 real-time MCUs, and Kevin Stauder, system engineer, automotive systems, Texas Instruments After a decade of rapid growth, global hybrid electric vehicle (HEV) and electric vehicle (EV) market sales increased a record 43 percent in 2020 over 2019. This much-anticipated global HEV and EV market surge occurs because of region-led […]

Leland Teschler • Executive Editor lteschler@wtwhmedia.com On Twitter @ DW_LeeTeschler The latest figures from the National Fire Protection Association show that only about 20% of all vehicle fires arise from problems in the vehicle electrical system—most fires have something to do with the fuel system. Seeing as electric vehicles will do away with problematic petrol, […]

Lithium-ion battery (LIB) safety is a major concern for designers. LIBs are generally safe to use if they have been properly manufactured and are integrated correctly into systems. However, the use of sub-standard materials and the possibility of manufacturing or design defects can result in hazardous conditions. As a result, there are many global safety […]

The short answer is ‘no.’ We might be getting closer, but there’s still no guarantee that we’ll get there soon. Some automakers are looking at 2024 for the introduction of solid-state batteries in EVs, but others don’t see that happening until 2030. Expectations are high but unfulfilled. This FAQ reviews the anticipated benefits of solid-state…

Keeping EV batteries cooled is the most common thermal management concern. However, batteries used in cold climates often benefit from being heated when temperatures fall. When undergoing fast charging or extra fast charging (XFC) batteries may need additional levels of cooling. This FAQ first considers various active and passive cooling technologies for EV batteries. It…

A few best practices for handling transients and over-currents help make electronic drivetrains more reliable. James Colby • Littelfuse, Inc. Automotive market analysts predict that by 2025, high-end vehicles will contain more than $6,000 in electronic components. Most of these advanced electronics will be in the growing number of electric vehicles (EVs). To ensure robust, […]

Leland Teschler • Executive editor Officials estimate it will cost $50 billion to field the chargers needed for the expected number of electric vehicles on U.S. roads by 2030. But it’s possible that spending every penny of this amount won’t prevent the extinction of the cross-country road trip. Here’s the logic behind that statement: It’s […]

STMicroelectronics has revealed new battery-management technology that increases reliability, safety, driving range, and cost-effectiveness of electric vehicles (EVs). EVs are predicted to reach cost parity with conventional combustion-engine vehicles before the end of this decade and overtake in sales volume by 2038. ST, leveraging its technical capabilities to help carmakers achieve these goals, has announced an […]

Bel Power Solutions today announced the BCN25-700-8, a 25 kW onboard battery charger that converts 3-phase AC voltage to DC voltage. The enclosure is made of aluminum alloy and is liquid-cooled. Providing 25 kW of output power for a single unit, and up to 100 kW of output power for 4 units, the BCN25 has […]
