The Colombian countryside is moving forward, among some obstacles is the little use of self-propelled assets in farm activities, the current ones, due to their technical characteristics, don't adapt to Colombian's geography, therefore, it's important to develop technologies that aim to eco-efficiency, taking advantage of Colombia's great biomass potential. In this way, it's proposed as an initial part of a macro-project that is developed by the Servicio Nacional de Aprendizaje (SENA) that seeks the incorporation of electric utility vehicles and their charging stations in the sowing and harvesting of cocoa. In this work, a physical-chemical characterization of two types of organic substrates (pigs and chickens manure) is done to obtain the methane energy potential for the design of an electrical station. As a relevant result, the sample obtained from the 1 to 3 proportion of pig manure highlight since it achieves a better production of methane in a retention time of approximately 30 days, achieving a daily load of the batteries in an estimated time of 6 hours, it contributes to the management of slow charge cycles according to its control algorithm and to a complete equalization of the 1.980 cells that make up the 6 modules of batteries.
