Addressing MLCC performance issues in high-voltage EV applications

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 »

Road test indicates existing electric trucks could replace millions of diesels on short-haul routes

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 »

Lyten introduces lithium-sulfur battery platform

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 »

Madrid transit agency orders 30 more electric buses from Irizar e-mobility

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 »

GM and Wolfspeed partner to develop silicon carbide power devices

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 »

Pre-Switch expands into new facility with 200 kW dynamometer and 250 kW DC power supply

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 »

Volkswagen’s ID.4 electric crossover has it all—practical and fun

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 »

Lower real EV inverter cost without compromising safety, quality, or test coverage

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….
