Resumen
The general objective of this research is to determine the energy efficiency and select the appropriate battery bank for a competitive solar prototype to reach a journey of 2500 km, in which two different sized battery packs are used, the first with lithium polymer modules and the second with Iron-Phosphate lithium modules. Firstly, it is important to verify its availability in the market according to costs, characteristics, features and limitations. In the framework of this study, it has been conducted several types of methodology, including the deductive method, which is necessary since the study of the different battery modules by the solar competency regulations is required and allowed; The comparative method is used since analysis will be performed to compare benefits and losses of each battery pack; It is also necessary to use the experimental method since with it will be possible to determine which are the adequate components for the implementation and tests carried out on each one of the banks and by using the analytical method it was determined the controller requirements and the Power unit. Therefore, Battery banks should provide nominal voltage values of 60 V and operating current rating up to 20 Amp. Once the amount of each of the necessary modules was selected, it was determined that the battery set with LIPO modules must use a voltage regulator to provide a voltage of 60 V and a current of 10.6 Amp which delivers an energy efficiency of 1.5 km in a controlled circuit. The second battery bank uses Lithium Iron-Phosphate cells and a voltage reducing regulator to deliver a voltage of 60 V and a current of 20 Amp to the module, which delivers an energy efficiency of 47.84 km on the same circuit, The LIPO battery bank can be used but for its better energy efficiency it is recommended to use the Lithium Iron Phosphate battery bank.
