GBatteries says its AI-powered protocol can charge an EV in 5 minutes
GBatteries has launched an AI-powered charging protocol designed to charge conventional Li-ion batteries as quickly as a car can be filled with gasoline. The company says its system can charge a 60 kWh EV pack to 119 miles of range in 5 minutes. Operating at the intersection of artificial intelligence, electrochemistry, signal processing, and high-power… Read more »
SiC vs GaN semiconductors for EV power converters: Tech Opinion
Just as engineers are starting to get used to the advantages (and quirks) of silicon carbide (SiC ) devices, another semiconductor material joins the fray: gallium nitride, or GaN. Though there are some superficial similarities between these two materials, and even some overlap in their areas of best use, it is my opinion that only… Read more »
Lightning Systems introduces new Ford Transit powertrain with 20% more range than predecessor
Lightning Systems, a Colorado-based developer of electric drivetrains for commercial fleets, has introduced a Generation 2 model of its Lightning Electric system for the Ford Transit with 20% greater range and a higher top speed. The Lightning Electric Ford Transit is a battery-electric drivetrain for the Ford Transit 350HD. Thanks to new thermally-managed lithium nickel… Read more »
Fraunhofer develops GaN power ICs with integrated sensors
Researchers from the Fraunhofer Institute have integrated current and temperature sensors, 600 V-class power transistors, freewheeling diodes, and gate drivers onto a gallium nitride (GaN)-based semiconductor chip. The new circuit measures 4 x 3 mm and enables high switching frequencies and a high power density, while providing fast and accurate condition monitoring, according to the… Read more »
A closer look at the losses in power semiconductors
A previous article examined loss mechanisms in traction motors, which tend to be the single biggest source of losses in a modern EV drivetrain. This time, the focus is on the various power semiconductors, as they are the next biggest source of losses. Also covered in brief are ways to mitigate these losses and design… Read more »

SST Vacuum Reflow Systems, a subsidiary of photonics and microelectronic company Palomar Technologies, has launched the SST 8300 Series Automated Vacuum Pressure Soldering System for IGBT power modules in high-reliability automotive and commercial applications. Offered in either single- or triple-chamber systems, the series enables above average void rates, heating up to 500° C, and fast… Read more »
Power Sonic introduces line of Bluetooth-enabled lithium batteries
US battery manufacturer Power Sonic has introduced a new series that adds Bluetooth connectivity to its LiFePO4 batteries. With the free app, users can monitor the state of charge, voltage, temperature, capacity, and overall health of any Power Sonic Bluetooth battery within 10 meters. The app also records any conditions detrimental to the health of… Read more »
Fraunhofer and Hitachi Metals create on-board charger with 3.8 kW/l power density
The Fraunhofer Institute and Hitachi Metals say they’ve produced an on-board charger (OBC) prototype that delivers both high power output and compactness by using soft magnetic materials developed by Hitachi. Hitachi says the technology enables the OBC prototype to generate a power density of 3.8 kW/l. Hitachi explains that there is typically a trade-off between… Read more »
Solid Power receives investment from Ford, says it’s ready for production in Q2 2019
Solid Power, a spin-out company of the University of Colorado, has partnered with Ford to continue development of its all-solid-state batteries (ASSBs) for EVs. The partnership will focus on further developing ASSBs towards automotive requirements. The partners will use Solid Power’s fully automated, roll-to-roll production facility, which the company says will be fully operational in… Read more »
