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?

    A smaller battery would be cheaper to buy, and less weight to carry around, thereby reducing energy used if other factors remain equal.

    It would in my view be worth producing two versions of most electric vehicles, one with say a 350 km range and one with a 1,000 km range, let the customer choose.

    I would expect the battery to weigh the same [within the limits of measurement] whether charged or discharged.
