Honda EV Electric Moped Prototype, 2004

With a length of 1,290 mm and weighing 44 kg, the Moped-EV is compact and light. Its nickel hydrogen battery, located inside an aluminum frame, is extremely light, dissipates heat efficiently, and, at 360 watt-hours, offers exceptionally long life. Powerful enough to climb a twelve-degree incline, the electric moped offers performance comparable to that of an internal combustion engine bike of the same class.
Unlike most other bikes, which employ a grip throttle, the Moped-EV features a two-stage lever throttle located beneath the right handlebar. Worked easily by the thumb, the lever throttle helps make riding easy even for less-experienced riders.

The Moped-EV features a unified module in the rear swing arm that integrates the motor with a controller, which regulates the driving functions and the discharge and recharging of electricity.

The Honda has long conducted research into the development of next-generation power sources that reduce noxious emissions and help slow global warming. In 1994, Honda developed the CUV ES, an electric scooter leased to government institutions. Following in the tracks of that revolutionary vehicle, the Moped-EV is designed to offer quiet, clean riding both for commuting and recreational use

Honda Numa Hybrid Scooter Prototype, 2004

The new prototype features an alternating current generator (ACG) with an idle stop function and the Honda PGM-FI electronic fuel injection system. In addition to an electronically controlled belt converter and a range of Honda environmental technologies, the new scooter features a dual series and parallel hybrid powertrain with a direct rear-wheel drive electric motor. Thanks to a compact power system and a rechargeable nickel hydrogen battery located under the front cowl, the hybrid scooter is about the same size as the Dio Z4, a standard-size 50cc scooter, and is only 10 kg heavier.

The hybrid scooter’s internal combustion engine and direct rear-wheel-drive electric motor function in two distinct modes. In series mode, when riding on flat ground and when high output is not required, the engine alone powers the electric motor. In parallel mode, used during acceleration and when high output is required, the electric motor assists the engine. In parallel mode, an electronically controlled belt converter automatically selects the optimum assist ratio.

The most efficient use of energy, the hybrid system charges the battery during deceleration and whenever possible and utilizes this power when higher output is required. In addition, the scooter enters idle stop mode, when the scooter is stopped, and whenever power is not needed, during deceleration. These advanced features allow the hybrid scooter to achieve 1.6 times the fuel economy of the Dio Z4 (when riding on flat ground at 30 km/h) and to produce 37% less carbon dioxide
