IAV’s new modular drive unit, presented at the recent Vienna Motor Symposium, combines an 80 kW (50 kW continuous) motor with a transmission, and can support electrification solutions in vehicle classes A to D. Many of today’s electric drives use a transmission with a fixed gear ratio. This has the advantage of simplicity, but is… Read more »

Optiphase and Opal-RT collaborate on real-time simulation for 5-phase EV motors
Optiphase Drive Systems and OPAL-RT, a specialist in simulation and hardware-in-the-loop testing, have formed a strategic alliance to offer real-time simulation capabilities for vehicle designers that integrate Optiphase’s 5-phase electric motor and drive system. Optiphase says it developed its 5-phase electric power and control technologies to overcome the limitations and workarounds inherent to 3-phase systems…. Read more »
Siemens Foundation announces $30-million program to develop EV charging workforce
The US-based nonprofit Siemens Foundation has announced EVeryone Charging Forward, a $30-million, 10-year program designed to develop an inclusive workforce for the EV charging sector, which has seen rising demand for skilled workers across the industry. According to a Princeton University study, between 777,000 and 5.1 million energy-related jobs could be created in the United… Read more »
The redesigned federal EV tax credit and other EV-related measures
Unpacking the Inflation Reduction Act The recent passage of the Inflation Reduction Act—a sweeping package of tax, health care and climate measures—was like the happy ending to one of those heartwarming “Save Christmas” stories. We may never know what Machiavellian machinations persuaded Senator Manchin to release Santa Claus, but the merry old elf is coming… Read more »
Toshiba’s new high-voltage automotive photorelay detects relay sticking and ground faults
Toshiba Electronic Devices & Storage has launched a new photorelay that’s designed for high-voltage automotive batteries, battery voltage monitoring, and the detection of mechanical relay sticking and ground faults. The new TLX9160T is an AEC-Q101-qualified photorelay that’s composed of a SO16L-T package, and features high-voltage MOSFETs and an avalanche current rating of 0.6 mA in IAV…. Read more »
Freudenberg’s new quick-release valves for EV batteries
Freudenberg Sealing Technologies has introduced a new generation of DIAvent valves, which allow reaction gases to escape from damaged lithium-ion batteries. The valves also maintain the continuous pressure compensation required for normal battery operation. If a battery gets damaged, liquid electrolytes can escape into the battery housing as hot gases. These must then be released… Read more »
New heating concept increases EV range and enhances passenger comfort
Heating an EV passenger compartment requires additional energy, which sometimes reduces the vehicle’s range. Engineering specialist IAV teamed up with Louisenthal, a manufacturer of banknote substrates, security papers and security foils, to develop an energy-efficient heating concept that requires considerably less energy while increasing comfort for drivers and passengers. At the heart of the heating… Read more »
California makes VW funds available for zero-emission freight and marine projects
The California Air Resources Board has announced that the first installment of $35 million in VW Environmental Mitigation Trust funding for Zero-Emission Freight and Marine Projects throughout California is now available via a competitive solicitation. A second solicitation offering an additional $35 million is expected to be released in mid-2022. Eligible projects: Scrap and replace… Read more »
The battery that breathes—Freudenberg’s pressure compensation system
EV batteries require pressure compensation both under normal operation and during emergency ventilation. Freudenberg Sealing Technologies’ DIAvent component combines these two functions into a single design, which will be used in the ABT e-Caddy and ABT e-Transporter, two Volkswagen vans that are popular in Europe and Mexico. To reduce battery weight and size, ABT uses… Read more »
Daimler and thysenkrupp partner to develop bipolar batteries
Under a project sponsored by the German Ministry for Economic Affairs and Energy, Daimler and the Fraunhofer Institute, together with German conglomerate thyssenkrupp and engineering firm IAV, are co-developing the design and production of bipolar batteries. Bipolar batteries are still in the laboratory stage and have not moved past pilot scale. The project, named EMBATT-goes-FAB,… Read more »
