ELECTRICALLY DRIVEN VEHICLE AND ELECTRICALLY DRIVEN VEHICLE CONTROL METHOD

摘要

An electric power source system includes a main electric storage device (BA) and a plurality of sub-electric storage devices (BB1, BB2). A converter (12B) is connected with a selected one of the sub-electric storage devices (BB1, BB2) and carries out a bidirectional voltage conversion between the selected sub-electric storage device and an electric power supply line (PL2). A control device (30) carries out electric charge control for the input control of electric power from a load device (MG2, 22) to the main electric storage device (BA) and the selected sub-electric storage device in accordance with a braking request of an electrically driven vehicle and also carries out switch control to switch electric connections between the plurality of sub-electric storage devices (BB1, BB2) and the power supply line (PL2). Until either one of the electric charge control and the switch control is completed, the control device (30) prohibits or limits the other.
