Renesas 8in1 PoC E-Axle
Renesas Electronics, in partnership with Nidec Corporation, has introduced the world’s first “8-in-1” proof of concept (PoC) E-Axle system for electric vehicles, integrating eight key functions within a single microcontroller (MCU). This innovative E-Axle solution combines components like a motor, gear, inverter, DC/DC converter, and onboard battery charger, all controlled by a single MCU, reducing size, cost, and complexity.
Featuring a 99% efficient inverter and high-performance components, the system lowers overall weight and component needs. Renesas aims to support EV developers by providing comprehensive solutions and software, which can accelerate the development of EV systems. This breakthrough was showcased at electronica 2024 in Munich.
Mistubishi to Ship SiC MOSFET Inverters
Mitsubishi electronics reported that it will begin shipping samples of a silicon carbide (SiC) metal-oxide-semiconductor field-effect transistor (MOSFET) bare die for use in drive-motor inverters of electric vehicles (EVs), plug-in hybrid vehicles (PHEVs) and other electric vehicles (xEVs) on November 14. Mitsubishi Electric’s first standard-specification SiC-MOSFET power semiconductor chip will enable the company to respond to the diversification of inverters for xEVs and contribute to the growing popularity of these vehicles. The new SiC-MOSFET bare die for xEVs combines a proprietary chip structure and manufacturing technologies to contribute to decarbonization by enhancing inverter performance, extending driving range and improving energy efficiency in xEVs.
Mitsubishi Electric’s new power semiconductor chip is a proprietary trench SiC-MOSFET that reduces power loss by about 50% compared to conventional planar SiC-MOSFETs. Thanks to proprietary manufacturing technologies, such as a gate oxide film process that suppresses fluctuations in power loss and on-resistance, the new chip achieves long-term stability to contribute to inverter durability and xEV performance.
Product Features
1) Proprietary trench SiC-MOSFET extends driving range and lowers power costs for xEVs
– Advanced miniaturization technology, cultivated in Mitsubishi Electric’s manufacture of Si power semiconductor chips, helps reduce on-resistance compared to conventional planar SiC-MOSFETs.
– Oblique ion implantation instead of conventional vertical ion implantation reduces switching loss.
– Power loss is reduced by about 50% compared to conventional planar SiC-MOSFETs, resulting in improved inverter performance, extended driving range and reduced power costs for xEVs.
EV Chargers for Multi-Famly Properties
Parks Associates’ white paper, Preparing for EV Adoption in Multifamily: The Coming Wave, reports that 32% of multifamily property owners and operators plan to install, upgrade, or replace EV charging stations within the next year. This increase aligns with anticipated growth in EV adoption among residents. In partnership with Cox Communities, the study highlights new trends in EV adoption and explores decision-makers’ plans for charger installations and retrofits.
According to Kristen Hanich, Director of Research at Parks Associates, rising EV adoption and expanding grants and tax credits are boosting EV charger deployment in multifamily properties. High demand for EVs in markets like California, where EVs made up 25% of new car purchases in 2023, further underscores this trend.
Currently, owners and operators are focusing on adding EV chargers to Class A and Class B properties, where EV ownership is highest. However, challenges like poor connectivity and availability hinder a smooth charging experience. As EV adoption grows, multifamily properties will need to improve both charger access and reliability to remain competitive.
Reliant Free Charge Nights for Chevy EVs in TX
Reliant and GM Energy have introduced the Reliant Free Charge Nights plan, offering Chevrolet EV owners in Texas free nighttime charging between 11 p.m. and 6 a.m. This new electricity plan is part of a collaboration aimed at accelerating EV adoption and supporting a sustainable energy future. Available at over 150 Chevrolet dealerships in Texas, the plan allows new EV buyers to start saving on charging costs immediately. Additionally, the plan is powered by 100% renewable energy through renewable energy certificates (RECs). Both new and existing Reliant customers with Chevrolet EVs can enroll by designating their vehicle in the GM Energy Smart Charging Portal.
8 EV Stars for Washington Uni.
GreenPower Motor Company Inc., a manufacturer of all-electric, zero-emission vehicles, has shipped eight EV Star Passenger Vans to Washington University in St. Louis for campus transportation, with two more scheduled for delivery later this quarter. These vans feature ADA-compliant lifts, wheelchair securements, versatile seating, dual charging capabilities, and optional bike racks, offering sustainable and accessible mobility. This shipment builds on the University’s existing fleet of five EV Star Passenger Vans, enhancing eco-friendly transportation options for students, faculty, and visitors.
Since October 1, GreenPower has delivered various electric vehicles, including school buses and additional EV Star models, nearly surpassing the previous quarter’s total deliveries. The company aims to sustain this momentum and end 2024 on a strong note.
