An exhaust gas energy recovery System has been presented with the purpose of converting the recovered energy into electrical energy to be used to complement or replace the conventional 12 V alternator in order to cope with increasing electrical load demands. Based on an estimate of the available exhaust gas energy a battery sizing study has shown that a capacity of 131 Ah or greater is required to remove the conventional 12 V alternator. The System control will focus on minimising EBP while maintaining a given average load demand. The switched reluctance technology has been chosen for the electrical generator based on the high speed, high temperature operating requirements, while the mechanical design has addressed challenges in thermal management, package space, bearing design, etc. and has resulted in a 12 V water-cooled System with the potential of generating up to 6 kW mechanical power at 80 k rpm. The next steps for the project are to build a small number of 'proof of concept' prototype units which will be tested on an engine to validate the predicted results.
