EMC for EVs: Understanding electromagnetic compatibility

Engineers who design power electronics supplied by the mains have had to contend with meeting various electrical noise and safety standards for decades now, but their counterparts in the automotive industry were mostly free to do as they pleased. This was mainly because 12 V isn’t considered a shock hazard and cars are effectively rolling… Read more »

Q&A with Rivian’s VP of Propulsion (Full Interview)

The electromobility revolution is gathering speed, but the world’s EV-makers have fallen behind popular tastes in terms of the form factors auto buyers want, and this has emerged as a roadblock to mass adoption. Buyers love SUVs and pickups, and automakers love the high profit margins associated with these models. Electric SUVs are starting to… Read more »

Rivian’s VP of Propulsion: Thermal issues are the dominant limiting factor for maximizing EV performance

Charged recently chatted with Rivian’s VP of Propulsion Richard Farquhar to learn more about the design and development of the company’s unique electric platform (read the whole story in our upcoming issue). Farquhar spent 15 years as Powertrain Director at McLaren Automotive, designing and developing some of the highest-performance propulsion systems in the world for… Read more »

Pierburg creates modular AC compressor for EVs with integrated motor and electronics

Pierburg, a subsidiary of German parts maker Rheinmetall Automotive, has developed an AC compressor for EVs that integrates the compressor, electric motor and power electronics into one modular, compact unit. In ICE vehicles, the AC compressor is typically driven by a pulley and V-belt. EVs lack this mechanism, so the AC compressor is driven by… Read more »

Hitachi starts mass production of 800-volt EV inverter

Hitachi Automotive Systems is starting mass production of its 800-volt, high-output EV inverter. The company says that, thanks to its strong cooling performance, the new inverter delivers twice the voltage and 2.7 times the power density of previous generations. Most EVs are based on a 400-volt system, so in order to increase driving range, additional… Read more »

Seven new EVs to be launched in Indian market in 2020

Most of the EV headlines tend to focus on California, China and Europe, but the electromobility revolution is quietly gathering momentum in India, a potentially enormous market where the government has proposed substantial EV incentives. At the 2020 Auto Expo, which is to be held in February in Greater Noida, no less than seven new… Read more »

Cree to supply SiC semiconductors to ZF for electric drives

Cree, a US maker of silicon carbide (SiC) semiconductors, has partnered with German parts supplier ZF Friedrichshafen to supply SiC semiconductors for electric drives. ZF will initially use Cree’s technology to fulfill pre-existing orders from several auto manufacturers for silicon carbide-based electric drives, but ZF hopes to make silicon carbide electric drivelines available to the… Read more »

Why did Porsche go to the trouble of designing an 800 V Taycan EV?

How higher-voltage battery packs enable faster charging ecosystems Porsche took on a considerable engineering challenge when it decided to design an 800 V EV system for the Taycan, because nearly every other hybrid and EV in the world operates at 400 V or less. There simply was not a wide range of high-voltage off-the-shelf parts… Read more »
