Abstract
A battery temperature rise causing system has a converting unit for converting voltage of electric power held in one of a rechargeable battery and an accumulator and applies the converted voltage to the other one, and a control unit controlling the converting unit to alternately perform first transfer of electric power from the battery to the accumulator and second transfer of electric power from the accumulator to the battery while changing the first transfer for the second transfer each time the battery voltage reaches a lower limit and changing the second transfer for the first transfer each time the battery voltage reaches an upper limit, and to increase temperature of the battery due to heat generated by electric current flowing through the battery during the electric power transfer.
