A study on component swapping modularity for battery module control system of a plug-in HEV based on feedback control

To enhance the interchangeability and compatibility of battery module control system in hybrid electric vehicles, the battery module of a plug-in hybrid electric bus is taken as research object to configure the poles of its closed-loop control system by using feedback control, which can effectively ensure system stability and response quality. Under the constraint condition of meeting the designed performance of control system, an optimization on the controller parameters of 4 battery modules with different capacities is conducted with BUSRTE driving cycle. The results indicate that the control systems of all four battery modules offer good fuel economy, charge sustainability and the interchangeability and compatibility of the control system, thus meeting the requirements of component swapping modularity.
