Abnormality detecting device of battery raising circuit

摘要

Problem to be solved: to provide an abnormality detecting apparatus of a battery warming circuit capable of reducing the time required for abnormality detection of the battery temperature raising circuit.In the abnormality detecting apparatus of the battery temperature raising circuit 40, the battery ECU 18 determines whether or not the heater voltage V1 acquired by the voltage acquisition part 19 is included in the voltage range between the heater which can be obtained at the normal temperature of the battery temperature raising circuit If the obtained voltage V1 between the heater is not included in the voltage range between the heater, it is determined that the battery temperature raising circuit 40 is abnormal.The voltage range between the heater is variably set in accordance with the power supply voltage V3 obtained by the voltage acquisition section 19.Diagram
