Dimensionamiento de la fuente de alimentación de energía mediante el diseño de un banco de baterías para el prototipo de Buggy híbrido 4x4.

Abstract

The high voltage batteryis one of the most important elements in the 4x4 hibrid buggy prototipe . In this case , it is necessary to dimension an energy source using engineering methods to ensure the quality of the assembly to meet the operating parameters of the electric motor . The Niquel-Hydride-Metalic cells used in the most commercial hibrid vehicle in the Toyota Prius Ecuador have been selected . In which each cell has a nominal voltage of 7.2V and maximun voltage of 9V, the nominal operating voltage requiered for the operation of the electrc motor is 48V-96V specified by the manufacturer. For which it is necessary to connected 12 cells in series to form a block of batteries obtaining a voltage of 96V, placed 3 battery blocks connected in parallel to obtain a greater performance as regards autonomy. As any power supply requieres a charger that allows the face to be made jointly, for this a charging system was implemented which can be connected to the 100 outlet that contain the facilitiens, for this a KBPC 10 diode rectifier bridge was implemented that is in charge of rectifying the current it alternates to continuous connected to an electrolytic condenser and several electronic elements to realize a suitable load . For the test of functionality it proceeded to the load of power supply of energy during 130 minutes then it was made road tests inside a determined circuit, in which measurements of voltage and current consumption were obtained obtainig an autonomo 800 meters, the largest current consuption by the electric transmission was 90 Amps at the time of overcoming the residence to rolling
