The next nifty EV feature: perpendicular steering
Add another item to the list of neat tricks that cars will soon be learning: the ability to maneuver sideways in order to slip into tight parking spaces. The OmniSteer project, funded by Germany’s Ministry of Education and Research, aims to develop a vehicle with “a lateral and transverse guidance system capable of performing orthogonal,… Read more »
Assisted steering system uses individual wheel motors for more efficiency and better range
Modern automobiles are complex beasts, with numerous subsidiary systems that consume energy. In an EV, more energy consumption means reduced range, so it can be well worthwhile to study more efficient ways to power the various accessories. One of these accessory systems is assisted steering, which reduces the physical effort required for the driver to… Read more »
Scientists increase manufacturing speed of electrode foils by 3x, promising lower costs
Researchers around the world are working on improving various aspects of battery performance – capacity, charging speed, usable life. Scientists at the Karlsruhe Institute of Technology (KIT) are focusing on the speed with which they can be manufactured, which has a direct effect on costs. The researchers have increased the manufacturing speed of electrode foils… Read more »
New modular battery concept to be demonstrated at Frankfurt show
The Karlsruhe Institute of Technology (KIT) will present a unique modular battery concept for electric buses at the upcoming International Motor Show in Frankfurt. The battery system consists of flat modules that can be stacked to reach the dimensions and electric characteristics desired. The idea is that, because the size and shape of the battery… Read more »
Bosch and partners research powerline communications for battery management
German researchers have launched a new project to improve battery performance in hybrid and electric vehicles through smarter battery management. The focus of the project is on using the power lines in a battery pack to transmit the data that allows individual battery cells to be monitored and controlled, eliminating the need for separate data-transmission… Read more »
German researchers seek to demonstrate that EVs are cheaper than ICEs
Do the lower operating costs of EVs justify their higher purchase prices compared to legacy gas-burning vehicles? That question may have no definitive yes-or-no answer (it depends on an individual’s driving habits), but more data is always welcome. The Karlsruhe Institute of Technology (KIT) and the Fraunhofer Institute for Systems and Innovation Research, in cooperation… Read more »
New HIU lithium-metal battery boasts 560 Wh/kg specific energy
Researchers at the Karlsruhe Technology Institute and the Helmholtz Institute Ulm (HIU) have developed a new lithium-metal battery that offers a specific energy of 560 Wh/kg with good stability. The researchers used a low-cobalt, nickel-rich layered cathode (NCM88), which offers high energy density. With the commonly used organic electrolyte LP30, however, the stability is unacceptable….
