HYBRID VEHICLE AND METHOD FOR CONTROLLING THE SAME

摘要

A power supply system includes a main electric storage device (BA) and a plurality of sub electric storage devices (BB1, BB2). A converter (12B) is connected to selected one of the sub electric storage devices (BB1, BB2) and performs a bidirectional voltage conversion between the selected sub electric storage device and a power line (PL2). In response to decrease of the SOC of the selected sub electric storage device in use, a switch request for switching between the sub electric storage devices is generated and the process of switching relays (SR1, SR1G, SR2, SR2G) is executed. In this case, during execution of the starting process or the stopping process of an engine (4), the generation of the switch request is suspended even if the decrease of the SOC is detected. Similarly, during the process of switching between the sub electric storage devices, the starting process or the stopping process is suspended even if a starting request or a stopping request for the engine (4) is generated.
