| dc.description.abstract | A Smart Laptop Charging Station Using Hybrid Solar Power Generation has been successfully designed. The purpose of designing this tool is to design a smart laptop charging station that is used to assist laptop users in charging their laptop with energy that is more environmentally friendly, as well as comparing the charging time for a laptop charging station with a manufacturer's charger. The working principle of this tool, the PZEM-004T sensor detects the current and voltage from the inverter, the battery supplies current to the regulator as a voltage adjustment to suit the needs of the microcontroller. After the sensor detects an object, the sensor sends a signal to the microcontroller to be converted into data, then the data is sent to the LCD as output to display the data. The average values of voltage, current and power used in laptop charging stations with micro cable ports are 210.25 V, 0.17 A, 42.29 W, type c cable ports are 221.41 respectively V, 0.246 A, 58.45 W, the blue pin cable port respectively is 232.58 V, 0.176 A and 41.70 W. The results of the comparison of the length of charging time between the micro cable port of the Laptop Charging Station and the manufacturer's charger have a time difference 2 minutes 3 seconds of charging time, while the comparison of charging time between the type c cable port of the laptop charging station and the manufacturer's charger has a difference of 56 seconds, and the comparison of the charging time between the blue pin cable port of the laptop charging station and the manufacturer's charger has a difference of 2 minutes 40 second. | en_US |
