In this chapter the problem of structural reconfigurability analysis is introduced and applied on over-actuated electric vehicle. This task is performed through the use of the bond graph tool, which is an adequate tool for dynamic modeling of complex systems, and for fault detection adn isolation. The latter is performed by exploiting the structural and causal properties of the bond graph model to generate analytical redundancy relations in a systematic manner. Then, the actual system diagnosis information is exploited to study the different possibilities of system structural reconfigurability conditions. Finally, an algorithm is proposed, so that this study can be performed in a systematic way.
