Ricardo develops new model-based EV battery control technology; evaluating new cell chemistries

Green Car Congress

One of the most significant impediments to an increased market share for plug-in vehicles is the high cost of rechargeable energy storage. This can represent a very significant cost element of a typical battery electric vehicle (BEV); manufacturers need to strike a balance between product affordability and available range between recharges.

DOE HPC4Mfg program funds 13 projects to advance US manufacturing; welding, Li-S batteries among projects

Green Car Congress

Efforts to commercialize light-weight, energy-dense lithium-sulfur secondary batteries (2510 Wh kg –1 ) have been stalled by ongoing problems with the battery’s membrane, which limits cycle-life. Sepion’s polymer membrane technology provides a counterpoint, yielding long-lasting lithium-sulfur cells.

EV Everywhere Blueprint outlines DOE technical and development goals for EVs for 2022

Green Car Congress

Reducing the cost of electric drive systems from $30/kW to $8/kW. When these goals are met, the levelized cost of an all-electric vehicle with a 280-mile range will be comparable to that of an ICE vehicle of similar size. That would take a 55 kW system cost of $1,650 down to $440 and increase power density from 1.1 kW/kg to 1.4
