ULVAC Inc recently announced that it has created and launched a very innovative battery-charging system for power-assisted bicycles by putting together a solar generator, a small wind power generator and a battery charger.
Called "Hybrid Cycle Pit," the power-assisted bicycle charging station will be installed beside the baseball field in Chigasaki City Park, Japan. It will be into operation starting July 10, 2011.
The charging mechanism of the Hybrid Cycle Pit is composed of a small 1.0 kW wind power generator (upwind, horizontal axis, propeller type), a 1.6KW solar power generator and a battery pack. The last one contains a discharging and charging control system, a lithium-ion back-up battery and a battery charger.
Ertical axis wind turbine
Lowest cut-in wind speed
1 m/s for power production
No noise, no vibrations (sound level
< 25 dB at 7 m/s from 10 m distance)
Adaptable for hybrid solutions
With solar and other sources of energy
Permanent power supply from wind/solar
And continuous battery charging
Technically advanced Maglev generator
No mechanical friction
Best price-performance ratio All weather resistant
(rain, ice, heat, salt, sand)
Independent of wind direction
Suitable for roof fixation
Maintenance-free
Safety for people and nature
