The invention includes a memory unit that stores electrical characteristics of a power receiving coil of an electric lawnmower and a power transfer coil of an external charger, wherein a battery side control circuit performs a test power transfer from a power transferring/receiving coil to the power receiving coil or the power transfer coil to obtain electrical characteristics of a power receiving side, compares the electrical characteristics to the electrical characteristics stored in the memory unit to determine whether the electrical characteristics are of a power transfer to the power receiving coil or of a power transfer to the power transfer coil, and performs control to switch to a power transfer mode with respect to the power receiving coil or to a power receiving mode with respect to the power transfer coil.
