Penn State team investigates battery requirements for eVTOL applications vs EVs

Green Car Congress

The unique operating profiles and requirements of electric vertical takeoff and landing (eVTOL) aircraft—also known as flying cars—present formidable challenges to batteries. Further, eVTOL batteries should continue functioning even after a safety incident occurs until a safe landing. —Yang et al. Yang et al. Yang et al.

Study Finds Strong Synergy Between Spark Ignition Engine Downsizing and Low-to-Moderate Alcohol Blend Fuels

Green Car Congress

A study by engineers from Mahle Powertrain Ltd and BP found strong synergy between spark ignition (SI) engine downsizing and fuel containing low-to-moderate amounts of alcohol, including ethanol and butanol. The team presented a paper on their work at the recent SAE 2009 World Congress in Detroit. Cairns et al. SAE 2009-01-0138).

BorgWarner suggests Valve-Event Modulated Boost system can offer 6-17% fuel economy benefit over already downsized and turbocharged engines

Green Car Congress

Christopher Thomas, BorgWarner VP, Advanced Engineering, Engine Group and VP, Advanced Engineering, Drivetrain Group presented the basic concepts of VEMB and current BorgWarner test results at the recent SAE 2012 High Efficiency IC Engine Symposium. Total cost of implementation is much less than $10/1%, he said. and Sisson, J. and Becker, M.,

Penn State team develops thermally modulated LFP battery; fast-charging, inexpensive, long-life for mass-market EVs

Green Car Congress

Furthermore, they found that the limited working time at the high temperature presents an opportunity to use graphite of low surface areas, thereby prospectively prolonging the EV lifespan to greater than two million miles. The very fast charge allows us to downsize the battery without incurring range anxiety. —Professor Wang.

The unit can be applied to naturally-aspirated or forced induction engines—though most likely will be applied to downsized turbocharged engines as an additional unit to the existing turbocharger. The electrical machine design and control system for this application is particularly challenging for a number of reasons, the authors note.
