Abstract

Although electric vehicles have been extensively promoted by governments around the world, their development is seriously hampered by the shortage of charging stations in remote areas. Once the electric vehicle is lacking electricity in the midway, the owners can only choose to wait for rescue. For this purpose, this study proposes an energy mutual aid control strategy for an electric vehicle to ensure the rapid power mutual supply of the vehicle owner. First, aiming at the low short circuit ratio (SCR) of the source subsystem in the electric vehicle and the low voltage as well as large current demand of the mutual aid device, the equivalent six-channel interleaved floating dual boost converter and its state-space function are constructed. Further, for the limitation of low frequency/sub-synchronous oscillation caused through constant power supply of the absorbed energy electric vehicle and weak source of the supplied energy vehicle, a disturbance observer based sliding mode control algorithm is proposed using equivalent state-space function to provide DC power with constant voltage/power by the standard. Furthermore, the proportional-resonant controller is proposed to solve the current sharing problem among six parallel channels, which reduces the heat loss and improves the service life of the device. Finally, simulation and experimental results illustrate the high performance of the proposed stabilization control algorithm.
