PURPOSE:To stably feed electricity to a control means and the like even if voltage fluctuates violently by constituting the power supply device to be com bined with a main power supply feeding high drive voltage to the driving device, the lighting means of a motor driven scooter, which is actuated by low voltage, and with an auxiliary power supply which stably feeds low voltage to the con trol means and the like. CONSTITUTION:A main power supply 1 is directly connected to a driving device 2, and the driving device 2 employs a motor specified by nominal voltage of 48V. The large driving force of the motor therefore allows a motor driven scooter to exhibit excellent power characteristics almost identical to those of an internal combustion engine. A DC stabilized power supply 5 as an auxiliary power supply inputs nominal voltage of 48V from the main supply 1, and stably drops it down to 12V nominally so as to be supplied to accessories such as a control means 4, a lighting means 3 and the like. By this constitution, nominal voltage of 12V is stably supplied from the DC stabilized power supply 5 even if the voltage of the main power supply 1 fluctuates violently due to traveling, sufficient luminous energy is kept on by the lighting means 3, and the control means 4 operates stably. |
