PENGISI BATERAI HANDPHONE MEMANFAATKAN KERJA GENERATOR DI DALAM HAK SEPATU

MOBILE CHARGER WORK UTILIZING GENERATOR INSIDE THE RIGHT SHOE (2014 : xiv + 34 pages + Bibliography + Attachments) REZA FEBRIANSAH 0611 3032 0212 Departement of Electrical Engineering Study Program of Electronic Engineering State Polytechnic of Sriwijaya Mobile phone battery is secondary battery that having uncontinue characteristic so that it have to rechargeable with supply energy to the mobile phone battery or we known as recharge using electricity from PLN through a tool that called “adaptor” which voltage was adjusted with handphone type. But the electricity from PLN not always available, for example when floooding, when we are in the beach and in other emergencies. To solve it is charger designed using 12V generator. By turning the gears are connected to the generator shaft, magnets in generator would spin around the coil and generates a magnetic force lines changing. Those changing will causes electromotive force that will be rectified so that in can be used to charge the battery. There are 3 types of charging condition, first is 6V Lithium Ion recharge, 3,7V 1,5Ah mobile phone charging and recharge, and the last is mobile phone charging using Lithium Ion battery as a source. Currents generated by generator is 5V, so there is available recharge. When in recharge and charging conditions, the output is ±5V with capacity of current is 0,44 - 0,52 Ah, so it takes a long time to do the charging. The size of generator output voltage depends on the number of rounds, if there are so many rounds, generator output voltage will high and vice versa.
