In recent years, multilayer ceramic capacitors (MLCCs) have emerged as an excellent capacitor option for the high-power electrical systems needed in electric vehicle (EVs) due to their small physical size, low inductance, and ability to operate at higher temperatures. However, engineers are facing two big challenges with MLCCs including DC bias that can cause capacitance loses of 80 to… Read more »
When it comes to long-haul trucking, battery-electric trucks face a number of challenges, including weight restrictions and the need for an ultra-high-power charging solution. However, despite what you may read in those “anything but EVs” articles, the jury’s still out on when, or whether, battery and charging specs will improve to meet these challenges, or… Read more »
Material supplier Lyten has introduced its new LytCell lithium-sulfur (Li-S) battery platform. The new platform was developed specifically for the EV market, and is designed to deliver three times the specific energy of lithium-ion batteries. Lyten has previously worked with the US government to test LytCell in defense-related applications, and is now ready to introduce… Read more »
Sponsored by BizLink There’s nothing like the excitement that comes with purchasing an electric vehicle for the first time. Of course, most attention is focused on the vehicle’s attractive features and performance, but equal consideration should also be given to how and where to charge the vehicle. Despite the growing number of public charging stations… Read more »
The Municipal Transport Company of Madrid (EMT Madrid) has ordered 30 electric buses from Spanish OEM Irizar e-mobility. This is the agency’s fourth order from Irizar, and will bring the number of zero-emission Irizar buses in its fleet to 85. The 12-meter Irizar ie electric bus has been running on Madrid’s roads since 2019. It’s… Read more »
General Motors and Wolfspeed (formerly Cree) have entered an agreement to develop and provide silicon carbide power devices for GM’s electric vehicle programs. The silicon carbide will be used in the integrated power electronics contained within GM’s Ultium Drive units. The silicon carbide power devices will be produced at Wolfspeed’s 200 mm-capable Mohawk Valley Fab… Read more »
Switching specialist Pre-Switch has expanded into a new San Jose, California facility. The new space is outfitted with a 200 kW dynamometer, a 250 kW DC power supply and test stations that have been custom-built to measure inverter efficiencies above 99%. Pre-Switch’s controller analyzes multiple inputs on a cycle-by-cycle basis, making adjustments in real time… Read more »
The Volkswagen ID.4, which went on sale in the US earlier this year, could turn out to be a very important vehicle for a couple of reasons. It’s the first of VW’s new-generation EVs to reach the US. That is, it’s the first to be built by the post-scandal, reformed and repentant VW, and the… Read more »
In the evolving world of eMobility one thing remains constant – the inverter is the heart and soul of electric vehicles. When it comes to testing inverters, the trend has been to pull tests further up the development cycle, using virtualization to simulate components at lower costs and test scenarios faster than in-vehicle field testing….

Johnson Matthey has entered into an agreement with OnTo Technology, a developer of battery recycling methods, to scale up OnTo’s process for the direct recycling of lithium-ion battery scrap. OnTo’s patented Cathode Healing process restores the coating material to use in new battery production, and avoids energy-intensive refining processes. Jane Toogood, Chief Executive of Johnson… Read more »
