DESIGN AND DEVELOPMENT of a MOBILE POWER CHARGING STATION via SOLAR and THERMOELECTRIC HARVESTING

The mobile power station design accommodates outlets with different voltages-220 volts AC, 12 volts DC, and 5 volts DC, suitable for both indoor and outdoor environments as an alternative source of power.The components used by the researcher to construct the Mobile Charging Station include a 100W Solar Panel and thermoelectric harvesting system.The solar charge controller has a Rated voltage of 12V.The Sealed Lead Acid Battery is specified at 12V 100AH, while the DC Watt-meter covers a range of 0-60V for voltage and 0-100A for current.The results indicate that the fully charged battery, without the solar panel but with some connected load, lasts for 10 hours.However, with increased load, the duration decreases, lasting for 8 hours and 6 hours respectively when the battery is at 100% state of charge without the solar panel.The researchers concluded that higher load conditions result in increased energy consumption from the battery.
