Optimization of Electric Cars with Solar Cells and Life-PO4 Batteries

Abstract

At this time the Makassar Aviation Polytechnic still lacks equipment in energy conversion subjects where one of them is a solar cell-based electric vehicle, this solar cell-based electric vehicle is urgently needed to support learning activities, In this study we made a solar cell-based electric car where this equipment can be used to support energy conversion courses, where in making this equipment the authors need equipment such as electric motors, controllers, solar cell batteries, battery management systems, solar charge controllers, Optimization of electric cars with solar cells is done by converting sunlight captured by the solar cell modules into electrical energy which is then channeled to the charge controller. The voltage on the charge controller is set at 56v 58v which is then forwarded to the battery management system. In this phase the electric current will flow to each battery cell so that the conditions between the battery cells are balanced. the research that has been done has resulted in the conversion of solar energy into electrical energy and the conversion of electrical energy into motion energy. After the manufacturing process is complete, we carry out a testing process where we use the electric car until the car cannot move anymore. The first is the solar cell testing process itself, where the testing process is carried out without a load and with a load and the results show that there is no significant difference to the input voltage or voltage. comes out to the load because the voltage has been regulated by the solar charge controller, and the second is testing the electric car, the first is the position of the solar cell is closed and the second the position of the solar cell is opened, after the experiment is done, the results are obtained which is compared with the time the solar cell is opened with the time the solar cell is open closed there is an efficiency of 13% from the beginning.
