Zusammenfassung:An electric vehicle is described having a frame (1 ) configured with a cell module (1A), a front anti-crash module (1 B) and a rear module (1C), each having a reticular structure formed by high-strength steel arms, welded together and each having a hollow structure with a quadrangular cross-section. A front axle unit and a rear axle unit (4) each including an electric drive motor (M) are associated with the front frame module (1 B) and the rear frame module (1 C). The frame comprises a floor (F), which also acts as a container for the battery pack (BP) for the electrical power supply of the electric drive motors (M) of the vehicle. New configurations of vehicle components are described, in particular of the door frames (21), of the suspension arms (7,8), of the wheel supports (5) and of the anti-crash longitudinal members (2L), which give rise to a drastic simplification of the manufacturing operations and production equipment costs, while maintaining a high degree of strength and protection for the driver and passengers in the event of a crash. In one example, the vehicle has a pick-up or van configuration with an arrangement of photovoltaic cell panels that improves the functionality and convenience of use for the user. Preferred embodiments of the electric power supply circuit of the battery pack are illustrated, which make it possible to drastically simplify the components of the circuit, to increase the efficiency of the charging process and to dynamically manage the charging process in order to keep the charge states balanced of the different battery modules (B1, B2, B3, B4) making up the battery pack. A preferred embodiment example of the structure of the photovoltaic cell panels (PV) with which the vehicle is provided is also illustrated. La présente invention concerne un véhicule électrique ayant un cadre (1) pourvu d'un module de cellule (1A), d'un module anti-collision avant (1B) et d'un module arrière (1C), chacun ayant une structure réticulaire formée par des bras en acier à haute résistance, soudés ensemble et ayant chacun une structure creuse ayant une section transversale quadrangulaire. Une unité d'essieu avant et une unité d'essieu arrière (4) comprenant chacune un moteur d'entraînement électrique (M) sont associées au module de cadre avant (1B) et au module de cadre arrière (1C). Le cadre comprend un plancher (F) qui sert également de contenant pour le bloc-batterie (BP) pour l'alimentation électrique des moteurs d'entraînement électriqu
