Fill her up is what you used to say to have your car tank topped with gasoline and it conveyed the idea of something that was done in the time you went to the kiosk to get some candy. This does not fit with the recharge of an electrical vehicle …

We are surely moving towards electric vehicle. In the next decade we will see EV taking the upper hand in terms of circulating vehicles volume. From that point on we will see a steady decrease of ICE -internal combustion engines- and the parallel decrease of gasoline use. That will have …

The quest for better batteries, meaning higher energy density and faster charging, is relentless. These two aspects are important, and leading research in this field, but there are also other factors that are considered, like weight, use of easily  available materials, longer operational life, easier production (and cheaper cost). There …

I stumbled on a recent article on the MIT Technology Review discussing the (expected) evolution of batteries for electric vehicles -EV. It makes for a nice reading also because it looks at the broad scenario of what it takes to shift from the 60+ million ICE -Internal Combustion Engine- vehicles …

  An electric vehicle is a truck transporting batteries. A Tesla 3 model weights 1800kg, its batteries 480kg, over one fourth of its total weight. Adding more mileage means adding more batteries but that increases the overall weight and could require bigger brakes and in turns bigger wheels all requiring …

McKinsey has published recently a most interesting report looking at the 2021-2050 period on the expected evolution of road transportation. It addresses several aspects that over the next 3 decades will change the whole road transportation landscape. The shift towards electrical vehicles will take up steam and already now it …

A new wind is blowing in most parts of the world, raising awareness on the environment and pushing towards greener forms of energy. In turns this pushes towards a wiser use of energy. Sometimes we miss the point that on the one hand we need to reduce the CO2 because …

The Wright’s Law, also known as “Experience Curve” states that each percentage increase in cumulative production (production volume) results in a fixed percentage of production efficiency increase. Studies carried out at the MIT have found that Wright’s Law is a little bit more accurate than the Moore’s Law (doubling of …

Electrical land vehicles are are reality and will become more and more common by the end of this decade. What about airplanes? Drones are flying objects that are battery powered, so why not aircraft? In this area we have seen significant progress leading to incredible result.  In 2018 an Airbus …

A crucial component in electric vehicles -EV- and most likely the most important one is the battery. Actually, it is not “a battery”, rather a battery stack. A Tesla Model 3 uses batteries that are 21 mm wide and 70 tall (not surprisingly they are called 2170 type). These batteries …
