Electric car
Abstract:
The invention relates to an electric car with (a) a first axle (12), (b) a second axle (14), (c) an electric motor (18) for driving at least one of the axles, which has an electric motor overall height (hM)t, and (d) a battery (22) for supplying the electric motor (18) with electrical energy, which has a battery overall height (hB), wherein (e) the electric motor overall height (hM) corresponds to the battery overall height (hB). According to the invention, (f) the electric motor (18) is composed of at least two electric motor modules (38.1, 38.2) and (g) the electric motor modules (38.1, 38.2) are arranged one behind the other in relation to a motor rotational axis (D18); (h) the electric motor modules (38.1, 38.2) have a common rotor shaft (4) or coupled rotor shafts (41); (i) the electric motor (18) and the battery are arranged at the same height; and (j) a battery mass centre of gravity (S22) of the battery lies in a central third (Q) between the axles (12, 14).
