Charging Quality of 100 Amper-hours Battery Using a Silicon Photovoltaic at Different Altitude in Semarang Region

Currently automotive battery technology evolve rapidly. The reasons stated are environmentally friendly because they do not produce carbon dioxide such as ICE. One form of battery power supply is from a solar power source. This paper discusses the charging of batteries with a capacity of 100 AH which are sourced by solar cell power (PV). The type of solar cell uses a 100-watt solar cell type silicon mounted on a portable basis and parallel connected. The position of solar cells are installed in three different areas in different around Semarang city. The altitude of each region is 0 -7.5 m, 350 - 450 m and 600 - 800 m above sea level. Battery charging duration of three altitudes has different time range. These condition are caused by the quality of light intensity that reaches the solar cell. At higher altitude has a relatively fast charging rate compared to lower positions due to a higher intensity. This information is used to determine the required solar cell panels on the vehicle to charge the vehicle battery and battery charging time.
