Maserati’s first fully-electric car powered by three Marelli 800 V motors
Italian automotive supplier Marelli developed and manufactured the three e-motors used in the new Maserati GranTurismo Folgore, and also provided its proprietary Adaptive Driving Beam Matrix LED headlamps and Telematic Control Unit connectivity system. The 800 V motors, which were developed over a two-year span and produced at Marelli’s Modugno plant in Bari, Italy, supply… Read more »
Volvo Trucks delivers heavy-duty electric concrete mixer truck to CEMEX
The iconic cement mixer truck, which fascinated so many of us in our childhood, is considered one of the most challenging vehicle classes to electrify, due to heavy loads and the need for continuous mixing of the concrete. However, Volvo Trucks and global construction materials company CEMEX have been working together since 2021 to make… Read more »
Marelli to supply BMS to a major EV-maker
Marelli will supply its Battery Management System (BMS) to an unnamed “major global carmaker” for its future EVs. Marelli will provide both BMS hardware and software for segment A, B, and C fully electric vehicles. The start of production is planned for 2026. The BMS will be based on a distributed architecture, which allows the… Read more »
A multi-physics approach to battery thermal management and runaway analysis (Webinar)
Thermal issues associated with the battery might affect its safety, reliability, lifetime, and performance. What if you can ensure the battery operates in safe temperature ranges while maximizing its performance, minimizing its degradation and avoiding hazardous conditions? Siemens offers an integrated battery design and thermal management workflow with multi-level modelling and multi-physics simulations. In this… Read more »
This provision of the IRA could deliver much bigger results than the EV tax credits
The so-called Inflation Reduction Act includes a long list of measures intended to promote e-mobility and renewable energy. The one that’s gotten the most press is the revamped system of tax credits for EV purchases—and naturally so, because that’s the measure that most drivers can see benefitting them directly. However, as John Voelcker writes in… Read more »
A closer look at graphite—its forms, functions and future in EV batteries
Q&A with Graphex CEO John DeMaio Reading the EV press, you might assume that lithium, cobalt and nickel are the stars of the battery show—they get a lot of coverage, as pundits debate the relative merits of NMC and LFP cathode chemistries and agonize over looming shortages. Meanwhile, over in the anode, there’s an unsung… Read more »
Renesas introduces second-generation gate driver integrated circuit for EV inverters
Semiconductor supplier Renesas Electronics has announced a new gate driver integrated circuit (IC) designed to drive high-voltage power devices, such as insulated gate bipolar transistors (IGBTs) and silicon carbide (SiC) metal-oxide-semiconductor field-effect transistors (MOSFETs) for EV inverters. Gate driver ICs are designed to provide an interface between the inverter control microcontroller unit (MCU) and the… Read more »
J.D. Power sets out to quantify progress towards EV adoption
If you can’t measure it, you can’t manage it, as the saying goes. The degree of progress towards full adoption of EVs seems like something that wouldn’t be easy to measure, but if anyone can do it, it’s probably data analytics powerhouse J.D. Power. The J.D. Power EV Index is a new analytics tool designed… Read more »
Kia EVs to use onsemi’s silicon carbide power module for traction inverters
onsemi has announced that its EliteSiC family of silicon carbide power modules has been selected for Kia’s EV6 GT model. onsemi says its power module enables high-efficiency power conversion from the DC 800 V of the battery to the AC drive for the rear axle. It also delivers package technology to minimize parasitics and thermal… Read more »
