Due to the growing need to have the largest number of energy-consuming elements integrated into vehicles (Compressor, fan, Starter, Heating, Fuel Pumps, Energy Export, Cooling Liquid Pumps, Power Steering, ABS Brakes, Windshield Cleaners, C4I Systems, Sensors, Vehicle Lights, etc.), the energy consumption and electric power needs of vehicles are growing. The technological trend for the increase of the available electrical energy, involves the incorporation of heavy batteries, which supply high voltage in continuous, using conventional converters. In this context, during the period 2015-2017 SAPA operations with the help of research agents CEIT-IK4, TECNALIA and University of Oviedo (and with the great support of the RETOS COLABORACIÓN 2015 program) has developed a high power electric power generation system, capable of converting the vehicle into a large generator group, capable of exporting energy in high and low voltage, of high power, eliminating the problems of logistics of generator sets to remote sites and that simultaneously, can be used as a complement to the propulsion system, in this case, as a starter engine. Although this development of power generation is already integrable in the GMP of a heavy weight off road vehicle, current market requirements lead to the essential reduction of weights, space and cost of power generation systems. Within this framework, SAPA proposes the present project with the main objective of developing a compact energy generation system embarked on a very high power density vehicle, adapted to the requirements of the applications and the market. In order to carry out this development SAPA will cooperate with entities expert in different subjects and with great interest in being present in the vanguard of electrification solutions for traction vehicles: LANCOR 2000: Expert company in the development of electric machines CEIT IK4: Research agent expert in electric machines R&D TENALIA: Expert research agent in DC/DC converters R&D The main development lines of the project will be as follows: O New high speed compact electric machine and its water-glycol and oil cooling system or New compact AC/DC alternator that is integrable with electric machine or New very high frequency compact DC/DC converter from commercial DC transformers. or Sequential integration of the new electric machine (two types of cooling: water-glycol and oil) with compact AC/DC and very high frequency DC/DC that would eventually be integrated into the new compact power generation system. The target market for the development of the compact high-density power generation platform is the ground military vehicles market. Sapa as a transmission developer and Moto Propulsors Groups for ground vehicles will incorporate this power generation system into future ground vehicle development programs.
