    摘要： An ECU calculates an evaluation value decrease amount D(−) in response to a reduction of unevenness of lithium ion concentration caused by diffusion of lithium ions resulting from a lapse of one cycle time ΔT, calculates an evaluation value increase amount D(+) in response to an increase of the unevenness of the lithium ion concentration caused by discharging during a lapse of one cycle time ΔT, and calculates a present value D(N) of a battery deterioration evaluation value D due to high-rate discharging, as a previous value D(N−1)−evaluation value decrease amount D(−)+evaluation value increase amount D(+). If battery deterioration evaluation value D exceeds a predetermined target value E, the ECU sets a discharging power limit value WOUT that is a limit value of electric power to be discharged from a battery, to a value lower than a maximum value W(MAX).

    摘要： A first monitor circuit 50 and a second monitor circuit 60 each having an identical configuration are provided in a voltage monitor. A threshold switching section 41 switches a threshold of each of switching units 51 and 61 provided in the respective monitor circuits 50 and 60 to a same value. Each of comparators 53 and 63 compares the threshold with a reference voltage to output a result of the comparison. A fault detecting section 42 compares the respective outputs from the comparators 53 and 63 with each other to detect a characteristic shift of the threshold of each of the monitor circuits 50 and 60.

    摘要： A vehicle which uses an internal combustion engine and a motor generator as drive sources is provided with a battery disposed under a seat and a fan for cooling the battery. Power is exchanged between the motor generator and battery via an inverter. An electronic control unit estimates the level of background noise which is noise other than the operating sound of the fan in the passenger compartment based on the vehicle speed and rotation speed, etc., of the internal combustion engine. Then, the electronic control unit calculates an operation command value for the fan based on the estimated background noise level and temperature level of the battery and controls the rotation speed of the fan through the operation command value. As a result, it is possible to effectively cool the battery while reducing sensible noise caused by the operating sound of the fan.

    摘要： Calculation of an offset value is permitted when a current value detected by an ammeter of a magnetic flux detection type is switched from a negative value to a positive value, or from a positive value to a negative value, and also a state where an absolute value of the current value is with in a predetermined range is continued for a predetermined time. When calculation of the offset value is permitted, the fact that an ignition switch is turned OFF is detected, and the current value detected by the ammeter is calculated as the offset value.
