Abstract

In a drive system including a battery, a power generation device (PGD) including a generator mounted to an engine shaft, and a drive device (DD) including a motor for driving a driven component, a drive controller performs a drive control for PGD and DD and a switching control for a switching device. During a parallel connection, respective high-voltage side terminals (HVTs) of PGD and the battery are connected to a HVT of DD, and respective low-voltage side terminals (LVTs) of PGD and the battery are connected to LVT of DD. During a series connection, HVT of any one of PGD and the battery is connected to HVT of DD, and LVT of another one of PGD and the battery is connected to LVT of DD, and terminals of PGD and the battery, which are not connected to DD, are connected to each other.
