I wonder what size battery for this Merc?

AncientMariner

From the June E&T magazine, A Mercedes-Benz EQXX prototype has been driven from Sindelfingen in Germany to Cassis on the French Riviera, a distance of more than 1,000 km, on a single charge.

Whilst certainly a good range, is it energy efficient considering the weight of the battery, which could have been reduced in return for a lesser range?

Whilst on the subject, does a fully charged battery weigh more (or even less) than a fully discharged battery?

    Hi,

    According to two physical theories of Einstein, mass and energy are just different manifestations of the same phenomenon, and therefore a battery contains energy in the form of its atomic mass and the electrical energy inherent in it. A battery when charged is more energetic or in other words 1 trillion times heavier and this shows an uncharged battery. The difference is so small that a standard scale will always show the same weight whether the battery is charged or not.
