DESAIN SEPEDA STATIS SEBAGAI PEMANEN ENERGI UNTUK PENGISIAN BATERAI

In this advanced era, the use of electronics is growing rapidly and to activate these electronics requires a power supply. The largest source of electrical energy supply uses mineral resources, namely coal. The effect of this steam power plant has many environmental effects. And the source of the electric generation of steam power will one day be exhausted because it is taking the earth's resources and can't be renewed. To reduce the use of steam power plants, renewable energy is needed. This renewable energy is in the form of utilizing kinetic energy at the spin of a static wheel paired with a DC generator so that it can produce electrical energy. The voltage generated by the generator is lowered first with a buck converter to allow the voltage to charge the battery. From the tests conducted, the average power generated during the 15 minutes pedaling the bike to charge the battery is 5.67 W with the average rotation of the generator of 865.58 rpm. From the calculations, it would take time to charge a battery of 2.5 Ah with an average current of 1.13 A, so the charging time from an empty battery to a full state takes 2.21 hours.
