<P>PROBLEM TO BE SOLVED: To suppress application of voltage that exceeds an element breakdown voltage, even when the breakdown voltage of an element is deteriorated because an inverter is in a state of low temperature. <P>SOLUTION: When a battery temperature Tb is less than a threshold value T1 and/or an inverter coolant temperature Tinv is less than a threshold value T2 (S110, S120), a first temporary base value Wbtmp1 is set on the basis of the battery temperature Tb (S160) and also a second temporary base value Wbtmp2 is set on the basis of the inverter coolant temperature Tinv (S170). An output limitation Wout of a battery 50 is set on the basis of the smaller temporary base value between the two temporary base values Wbtmp1, Wbtmp2 (S180, S140, S150). Thus, even when the inverter coolant temperature Tinv is less than the threshold value T2, application of voltage exceeding an element breakdown voltage to a high-voltage system power line, which occurs due to a serge voltage, can be suppressed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
