The low voltage power architecture used in EV traction inverters drives control electronics and provides gate driver power for the main traction IGBTs/MOSFETs. It must also provide redundancy to meet ASIL requirements. This requirement represents a special challenge as it means the Emergency Power Supply (EPS) must operate from low voltage and high voltage sources… Read more »

Simplified power analysis on multiple electric motor powertrains
Sponsored by CSM High-performance electric vehicles run with two, three or even more electric motors in the powertrain. Tuning the motor control is complex and requires precise performance analysis in order to test the desired driving characteristics. Early in the development process, the interaction of the individual inverters and electric motors is analyzed on powertrain… Read more »
A closer look at why heat pumps are dominating EV HVAC systems
Heating or cooling the interior cabin of an EV substantially affects the vehicle’s on-road efficiency, and the HVAC system often gets the proverbial “rented mule” treatment. In an ICE vehicle—particularly an underpowered one—there is a visceral reminder that running the AC, at least, costs something, since there is a palpable hit to acceleration whenever the… Read more »
Breakthrough technologies in capacitor solutions for power electronics in EVs
Power capacitor technologies affect every vehicle and charger in the electromobility industry. Join this session at the Charged Virtual Conference on EV Engineering, presented by TDK Electronics, where we will discuss the latest breakthrough technologies in film, aluminum and ceramic capacitors solutions and show real-world case studies for power capacitor use in on- and off-board… Read more »
ABB charges into the future with Formula E
The global electric racing championship Formula E has been a huge success by any measure. Automakers like Mercedes-Benz, Porsche, Nissan, and Jaguar have embraced the series, which is surely the world’s most prominent showcase for electric vehicle performance. Charged attended the New York City E-Prix in July, and spoke with several execs from EV infrastructure… Read more »
HEVO to commercialize ORNL’s dynamic wireless charging technology
The DOE’s Oak Ridge National Laboratory has licensed its wireless charging technology to Brooklyn-based HEVO. The system is designed to provide high power levels in a small package, and also supports dynamic charging, which could one day allow EVs to be charged while in motion. HEVO will work with ORNL to further develop the technology… Read more »
How Formula E helps ABB develop new e-mobility products
Global electronics giant ABB is involved in many aspects of the electromobility industry, from charging infrastructure to batteries to utility integration to robotics. It’s quite fitting that ABB is the lead corporate sponsor of Formula E, the all-electric racing series that’s now in its seventh season. Charged met with several ABB executives at the recent… Read more »
New 3-phase High-Voltage Breakout Module for electrical power analysis of vehicle powertrains
Sponsored by CSM CSM Gmbh, the industry leader of innovative measurement and data technology for 38 years, announces the newest product to its suite of measurement modules for the development of electric vehicles. This new HV Breakout-Module has been specifically designed to meet the international safety standards required for the use of equipment in high-voltage… Read more »
Canada to end new gas and diesel vehicle sales in 2035
The dominoes are falling. Several regions of the world, including the UK, California and Massachusetts, have announced proposals to phase out ICE vehicle sales by 2035, and now Canada has followed suit, bringing its previous goal of 100 percent EV sales by 2040 forward by 5 years. (The provinces of British Columbia and Quebec have… Read more »
Power Integrations new automotive-qualified silicon diodes for high-switching-speed designs
Power Integrations, a maker of high-voltage integrated circuits for energy-efficient power conversion, has announced its 600 V, 12 A Qspeed diode, the AEC-Q101-qualified QH12TZ600Q. The company says the device’s Qrr of 14 nC at 25° C improves the efficiency of an onboard charger’s PFC stage and reduces the thermals of the PFC MOSFETs. Senior Product… Read more »
