<p>The high efficient energy saving electric vehicle comprises a set of rechargeable batteries (7) as its power source and several electrical driving motors (1, 2) having different power levels each other, and each motor (1 or 2) has its own electric circuit system and switchgear. When the vehicle begins to start or is driven on uphill road and thereby is subjected to a higher resistance, the motor (1) having higher power level with the motor (2) having lower power level are simultaneously operated to generate a resultant force. When the force of vehicle inertia is increased and the resistance is relatively decreased after starting, only the motor (2) having lower power level, which has the highest revolution acting on a driving axle being greater than that the motor (1) having higher power level has, is operated. In this manner, the energy consumption can be saved so as to prolong the driving distance and duration per one charging.</p> |
