Document Type and Number:
Japanese Patent JP5502603
Kind Code:
B2
Abstract:
In an apparatus for heating a battery of a vehicle, having an electric rotating machine and buck-boost converter between the battery and rotating machine to step up/down voltage outputted from the battery to be supplied to the rotating machine and step up/down voltage generated by the rotating machine to be supplied to the battery, it is configured to have a first capacitor interposed between wires connecting the battery to the converter, a second capacitor interposed between wires connecting the converter to the rotating machine, and a heating controller to control operation of the converter to generate current similar to rectangular wave current and input/output the current between the battery and the second capacitor through the first capacitor so as to heat the battery. With this, it becomes possible to efficiently heat the battery so that the battery can output expected power, without adversely affecting the size of the apparatus.
