In the near term, quantum sensors are being developed that can more accurately measure electric vehicle (EV) battery capacity, assess battery safety, and reduce vehicle weight. In the longer term, quantum batteries have been proposed that could … [Read more...]

It’s no secret electric vehicles (EVs) are at a crossroads — while demand varies, the International Energy Agency (IEA) predicts 17 million EVs will be sold by the end of this year. That number translates to a more than 20% year-over-year increase … [Read more...]

Electric vehicles (EVs) have emerged as a promising solution to combat climate change and reduce the environmental impact of transportation. As the world increasingly recognizes the urgency of transitioning to cleaner energy sources, the rise of EVs … [Read more...]

Electric vehicles (EVs) commonly use mechanical contactors — high-voltage switches that control the flow of electricity — for charging. However, unlike most other vehicle and infrastructure parts, contactors have not advanced in efficiency. Most … [Read more...]

Today’s vehicles are loaded with electronics, sensors, control units, safety features, infotainment and advanced driver-assistance systems (ADAS), as well as dozens of small and big traction motors. Providing, managing, and delivering the required … [Read more...]

Global commercial EV sales are expected to roughly double this year over 2023, while passenger EV sales could increase by 21%. In the US, BloombergNEF anticipates that passenger EV sales could account for 13% of new-car purchases and reach just under … [Read more...]

Electric vehicles (EVs) have several components that deal exclusively with power management. The components include: A battery pack A battery management system (BMS) Power electronics Electric motors A regenerative braking system … [Read more...]

Electric vehicle (EV) smart energy management encompasses a broad ecosystem, optimizing charging, efficiency, and performance. This article reviews the ecosystem’s key segments, from electric chargers and power grids to primary EV systems such … [Read more...]

While most trade shows promise education and networking opportunities, Electrify Expo takes it a step further by combining fun, adventure, and hands-on experiences. North America’s largest electric vehicle (EV) festival kicked off in San Francisco on … [Read more...]

ISO 26262, titled "Road Vehicles — Functional Safety," is an international standard specifically designed to ensure the functional safety of electrical and electronic systems in road vehicles. The standards have a 12-part risk-based safety assessment … [Read more...]

Conveyors have been used since the start of automotive manufacturing in the early 20th century. Henry Ford leveraged them while standardizing the assembly line, and they’ve been a manufacturing mainstay ever since. Throughout the last 100-plus years, … [Read more...]

The gap between an electric vehicle's (EV) transmitter and receiver coils during wireless power transfer (WPT) affects six parameters: Coupling coefficient Mutual inductance Alignment sensitivity Magnetic field strength Resonant … [Read more...]

There are multiple challenges associated with vehicle-to-grid (V2G) systems. Of course, they must interface efficiently and safely between the vehicle and the grid without interfering with the grid’s operation. They’re also expected to meet multiple … [Read more...]

In late 2021, a vulnerability in an electric vehicle (EV) charging app revealed the full names, addresses, and charge histories of more than 140,000 UK users. Last year, Shell patched a weakness in one database that could have led to a similar fate, … [Read more...]

Compensation in wireless power transfer (WPT) refers to using additional circuit elements to counteract the reactive power in the charging system. Simple compensation topologies are S or P-type, while basic compensation topologies include SS, SP, PS, … [Read more...]

As transportation companies face increasing pressure to meet sustainability goals, transitioning from diesel and gas-powered fleets to electric vehicles (EVs) is becoming more critical. However, this shift presents significant financial challenges. … [Read more...]
