Designers of power conversion systems in EVs strive for maximum power density. Component packaging and cooling mechanisms become increasingly important in achieving this goal. Infineon and Silicon Austria Labs (SAL) collaborate to push the boundaries by going beyond current design requirements. Together, they develop new cooling concepts that can improve power density, simplify manufacturing, and… Read more »

DOE allocates $50 million to help automotive suppliers adapt factories for the EV supply chain
The DOE’s Office of Manufacturing and Energy Supply Chains (MESC) has announced $50 million in grants for six states with significant automotive workforces to help small- and medium-sized suppliers adapt their manufacturing facilities to serve the EV supply chain. The announcement on state allocations follows an April 2024 Request for Information, seeking input on state/federal… Read more »
New technology platform pinpoints EV battery hotspots
Sponsored by Littelfuse. New technology platform enhances the performance and lifespan of EV batteries. Lithium batteries offer the highest power density compared with other battery chemistries. Lithium batteries can store more energy in a smaller, lightweight package than any other type of battery. As a result, Lithium-based batteries are the battery type of choice for… Read more »
Paired Power: For EV charging at remote sites, a microgrid may be better than an off-grid solution
Off-grid charging solutions are a hot topic, and they’re not just for remote sites that have no grid access. Some customers choose an off-grid solution that incorporates solar power and energy storage in order to avoid the long lead times that are often required to get a new utility interconnection, and/or to offer a backup… Read more »
Reliability, uptime and the next generation of EV chargers
Sponsored by Power Innovations International. As EVs continue increasing from a very small portion of the vehicles sold annually to a more mainstream presence on roads around the world, consumers and manufacturers are grappling with plenty of important questions. One set of these questions centers around a general “feeling” – that is, “How much does… Read more »
Volvo, ZF, Cummins win $441 million in DOE funding to accelerate heavy-duty electric truck production
The US DOE has awarded nearly half a billion bucks to three companies under the Domestic Manufacturing Conversion grant program to help accelerate the production of heavy-duty electric trucks and related powertrain components. Volvo Technology of America will receive $208 to upgrade facilities at the Volvo Group’s Lehigh Valley Operations truck assembly site in Macungie,… Read more »
DOE announces $1.7 billion in grants to convert facilities for EV production and support US auto workers
Some folks fear that the transition to EVs will lead to major job losses in the auto industry—and not without reason, as EVs require different (and fewer) components than legacy ICE vehicles. Auto plants around the country are in danger of downsizing or shutting down altogether, and helping these facilities to retool for EV production… Read more »
Microchip offers new on-board charger package of automotive-qualified devices
Microchip Technology is offering an on-board charger (OBC) package designed to help developers speed their time to market by using key technologies from one supplier, including the control, gate drive and power stage. The package uses a selection of Microchip’s automotive-qualified digital, analog, connectivity and power devices, including the dsPIC33C Digital Signal Controller (DSC), the… Read more »
Transphorm releases reference design for bidirectional GaN power supply for EV chargers
US-based GaN semiconductor producer Transphorm has released a new 300 W DC-to-DC GaN reference design for two- and three-wheeled EV battery chargers. The TDDCDC-TPH-IN-BI-LLC-300W-RD design uses TP65H150G4PS 150 mOhm SuperGaN field-effect transistors (FETs) in a TO-220 package to power a high-performance, high-efficiency energy harvesting and distribution battery charging system, according to the company. The TDDCDC-TPH-IN-BI-LLC-300W-RD… Read more »
