Paul Scherrer Institute and Toyota RD team finds tiny memory effect in Li-ion batteries; implications for vehicle battery management systems

Green Car Congress

The memory effect of the battery is written in a cycle with partial charging (here, 50% of the battery’s storage capacity) followed by complete discharge. In the subsequent cycle, the memory effect is evident through an overvoltage (small “bump”) at precisely the same point at which the partial charging cycle terminates.

Mazdas new SKYACTIV gasoline and diesel engines are steps on the road to its Ideal Engine; focus on compression ratio

Green Car Congress

From a powertrain frame of reference, Mazda is planning a building block strategy—i.e., reducing displacement to improve fuel economy and offsetting the resulting loss of power and torque via charging—is an effective approach to reducing fuel consumption, Mazda has chosen a different route. Although downsizing—i.e.,

Inventing Postscript, the Tech That Took the Pain out of Printing

Cars That Think

Laser printer A device that, like a xerographic copier, draws an image on a drum, but with a laser beam instead of lenses; applies toner to the charged image area; and transfers the toner to a sheet of paper, melting it into the paper to set the image. A “Jam” session PARC was then using a programming language called Mesa. Then Canon Inc.,

note the potential of each technology and explain what advances must occur with each if they’re ultimately to be deployed. The percentages are higher in Europe and Japan, at 10% and 15%, respectively, largely because of favorable economics and government policies.) In their study, Yang et al. Credit: ACS, Yang et al.
