<p><P>PROBLEM TO BE SOLVED: To provide a controller of an electric vehicle, which is capable of exchanging an auxiliary battery with the other vehicle during traveling when power of the auxiliary battery is lowered. <P>SOLUTION: The controller of the electric vehicle includes: a main battery which supplies power to a motor; the detachable auxiliary battery; a boosting and step-down transformer which steps down the power supplied from a driving system circuit to supply the same to the auxiliary battery and boosts the power supplied from the auxiliary battery to supply the same to the driving system circuit; a battery control part which monitors the remaining capacity of the main battery and auxiliary battery and controls their charge and discharge, respectively; and a communication device capable of communication with an integration center. The battery control part switches, based on a user's instruction, a target value of the remaining capacity of the auxiliary battery between a first value and a second value which is larger than the first value and includes a battery memory part which memorizes a state of the auxiliary battery. The communication device transmits information on the auxiliary battery to the integration center when the remaining capacity of the auxiliary battery, which is memorized in the battery memory part, is equal to or more than the second value. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
