HSE (Hydro and Solar Energy) Hybrid Mobile Charging Station

Abstract

The number of smartphone users in the Philippines was estimated at 30.4 million in 2017 and was expected to rise by 40 percent in the year 2021, causing an increase in electricity consumption. This study aimed to create a charging station that could charge android mobile phones using water and solar energy as sources of electricity. Rivets, screws, and allen screws were used to connect each rectangular acrylic plastic sheet to the aluminium angle bars, forming a 240 cm x 60 cm rectangular body. Two tanks were placed on the upper and lower parts of the station. A pipe was placed to connect the upper tank and the crossflow turbine. Another pipe was placed between the crossflow turbine and vortex turbine. One light sensor was put at the top of the station while one ultrasonic sensor was placed on top of each tank for the detection of the buoyant device. Three LEGO Mindstorms NXT brains were used to collect data from the sensors and control the activities of LED bulbs, motor and buzzer. A water pump was installed to transfer water from lower to upper tank manually. The charging station showed 100% functionality in charging android mobile phones and charging batteries using water and solar energy. All the NXT brains were able to receive data from the sensors and were able to give instructions to actuators correctly with 100% accuracy. It was concluded that the HSEHybrid Mobile Charging Station could charge android mobile phones using water and solar energy.
