The experts at Mentor Graphics walk us through the simulation and analysis of a battery pack cooling system. In the business of battery pack design, one of the main considerations is cooling. The pack must have a uniform and stable temperature for the batteries to perform adequately during worst-case conditions. Even within a single cell,… Read more »

2014 Mercedes-Benz B-Class Electric Drive
After a gradual build-up, Daimler’s automotive brands are now showing their stuff in the EV arenas of three continents. Stateside, the spotlight lands on the new, competitively priced Mercedes-Benz B-Class Electric Drive. Daimler AG, the parent company of Mercedes-Benz USA (MBUSA), hasn’t been the most visible mover or shaker in electric mobility up to this… Read more »
Freudenberg Group’s new line of Li-ion battery separators
The separator is a critical component of a battery. It provides a barrier between the anode and the cathode while enabling the exchange of ionic charge carriers from one side to the other. For over 40 years, the Freudenberg Group has been producing separators for nickel-based batteries, such as the nickel-metal hydride (NiMH) cells widely… Read more »
ORNL team demonstrates high-voltage solid-state battery with impressive cycle life
Researchers at the Oak Ridge National Laboratory have demonstrated a solid-state high-voltage (5 V) lithium battery with an extremely long cycle life (10,000 cycles) and high Coulombic efficiency (99.98%). The solid electrolyte enables the use of high-voltage cathodes and lithium anodes with minimal side reactions. The energy stored in a battery of a given size… Read more »
Daimler sells stake in Tesla for $780 million in cash
Daimler has reorganized its financial relationship with Tesla, selling its 4% stake in the California carmaker. The cooperation between the partners on the Mercedes-Benz B-Class Electric Drive is unaffected. “We are extremely satisfied with the development of our investment in Tesla, but it is not necessary for our partnership and cooperation,” said Daimler Board Member… Read more »
Elon Musk: Tesla and Toyota may form a new partnership in a couple of years
Tesla and Toyota might just patch up their differences and form a new partnership some day, Elon Musk told reporters at an event for the start of deliveries in Japan (with a cool backdrop of three Model S in a showroom high above Tokyo). “If you look out maybe two or three years from now,… Read more »
Chinese and US policymakers cooperate to spur EV adoption
The University of California, Davis, and the China Automotive Technology and Research Center (CATARC) have agreed to work together to establish the China-US ZEV Policy Lab, a research institution for US and Chinese ZEV/new energy vehicle policies. The California Air Resources Board (ARB) and China’s National Development and Reform Commission (NDRC) will co-chair the new… Read more »
Are auto dealers the EV’s worst enemy?
It’s safe to say that car dealers aren’t a particularly beloved bunch. Shopping for a car may not be as bad as going to the dentist, but for many people, it’s right up there. Technically-minded buyers find it frustrating to try to glean some factual information from the typical rambling sales pitch, while more gentle… Read more »
Membrane technology and the importance of venting EV electronics
Protecting a car’s sensitive electronics throughout its lifetime is a must, whether it’s a conventional ICE vehicle or an EV. However, the larger electronics in plug-in vehicles have more power, more heat and higher pressure differentials that present new technological challenges to OEMs and suppliers. Any power semiconductor inevitably generates heat while conducting current, due… Read more »
Harley-Davidson’s Chief Engineer on the development of Project LiveWire
As Harley-Davidson tours America testing the waters for its prototype electric motorcycle, LiveWire, early riders like what they see and hear. For decades, few names have been as synonymous with traversing the American landscape as Harley-Davidson. After 111 years, Milwaukee, Wisconsin’s Harley-Davidson Motor Company has survived many ups and downs, including outlasting the Great Depression,… Read more »
