Electric scooter

Two-wheel vehicles have always been a practical transportation solution for individuals in urban agglomerations, where the average speed of travel for a vehicle with 4 wheels often fall under the walking speed due to the number of cars and transport infrastructure. When this mobility is combined with a special propulsion system the result is a clean vehicle that contribute substantially to solving two of the most distressing problems of the inhabitants of cities and local government: transportation and environmental protection.

Motorcycles and electric scooters enjoy growing popularity, due mainly to continued growth in oil prices. Battery technology made significant progress, making this mode of transport ever more interesting for potential users.

  • The energy cost per km is about 25% of the gasoline equivalent
  • Much less noise pollution
  • No noxious emissions
  • Recharge possibility of the batteries wherever public network power supply is available (even at home)
  • Reduced maintenance costs - for labor and consumables (eg. does not require oil changes, various filters, etc.)

  • Purchase price higher than the equivalent models equipped with internal combustion engine
  • Reduced autonomy , but sufficient for commuting within the city / town
  • Relatively high recharge time (of the order of hours)

Characteristics of main parts which equips the electric scooter.

Batteries are located in the space under the scooter saddle and are covered by the shroud; special support and attached elements permit easy removal and replacement.

The batteries have the following characteristics:

  • Type of batteries: VRLA lead-acid batteries or, depending on price, Ni-MH or Li-Ion batteries
  • Total voltage: 48 V d.c.
  • Capacity: 24 Ah
  • maximum continuous operation current 50 A
  • Sealed, maintenance-free batteries can operate in any position

The brushless DC permanent magnet electric motor was chosen because of its superior characteristics vs. brushed DC motors regarding reliability, gauges, thermal characteristics. The engine has a rated power of 1.3 kW at a speed of 5000 rpm.

The electronic drive system that controls the motor has the following main features:

  • Control circuit type: PWM, analog, controlled by resistive position transducer
  • Power circuit type: switching, 3 phase, equipped with V-MOS power transistors
  • Automatically limiting the load current
  • Load short-circuit protection
  • Overheat protection of power transistors

The electronic battery charger ensure full and proper recharging of the batteries in a reasonable amount of time (typically 10h).

  • Supply voltage: 220 V AC single phase 50Hz
  • Thyristor type rectifier circuit with load current measurement and control
  • Maximum current: 3 A c.c.
  • Automatic limitation of the maximum load voltage
