摘要:
A vehicle includes a power storage device, an air blower, and a control device. The air blower sucks air in the vehicle interior of the vehicle and blows cooling air to the power storage device. The control device controls the air blower such that the air volume to the power storage device is suppressed more when at least one of doors is open than when all of the doors of the vehicle are closed.

An electronic apparatus (a portable terminal apparatus 2) having a displaying function in a housing unit thereof that can be opened/closed or is rotatable, including a displaying unit 18 that displays a vertically oriented screen or a horizontally oriented screen 176, and a controlling unit (a CPU 90) that, when text information or information including a text is displayed in the displaying unit, sets a displaying column (a text displaying column 178) in the full lateral width that the horizontally oriented screen has and can be displayed, in the horizontally oriented screen 176 set on the displaying unit, and causes the information to be displayed in the displaying column.
摘要:
A fan motor is controlled via a switching circuit from the moment when a cooling fan control routine is started until the moment when the rotational speed of the fan motor reaches a control-switching speed so that the higher the detected auxiliary battery voltage is when the cooling fan control is started, the lower the command duty ratio that is set. Accordingly, it is possible to activate the fan motor more reliably and to avoid generating excessive operating noise by the cooling fan when the fan motor is activated.

A battery characteristic detecting method according to the invention includes a first step in which constant current discharge from a battery is performed at a predetermined current value, and a voltage during constant current discharge is measured; a second step in which overpotential for mass transfer control in the battery or resistance for the mass transfer control in the battery is calculated based on the voltage measured in the first step; and a third step in which a determination that a characteristic change has occurred in the battery is made, when the overpotential for the mass transfer control in the battery or the resistance for the mass transfer control in the battery calculated in the second step is larger than a predetermined threshold value.

A maximum dischargeable current Idmax obtained when electric power output from a battery is increased from a battery current Ib and a battery voltage Vb at present under internal resistance R at present (an operating point 510) until the battery voltage reaches a lower limit voltage Ve (an operating point 520), is shown as follows: Idmax=Ib+(Vb−Ve)/R. Therefore, in accordance with multiplication of the lower limit voltage Ve and the maximum dischargeable current Idmax, it is possible to predict maximum dischargeable electric power at which the battery voltage does not become lower than the lower limit voltage even if discharge limitation is temporarily relaxed, as a relative value with respect to the battery voltage and the battery current at present. When the discharge electric power limitation for the battery (the power storage device) is temporarily relaxed in accordance with a discharge request made by a load, a discharge electric power permissible value is set to correspond to the maximum dischargeable electric power, such that the output voltage of the power storage device does not fall outside a controlled voltage range from the lower limit voltage to an upper limit voltage.

摘要:
When a drive power demand Pv* is greater than 0, the control procedure of the invention sets the greater between an engine speed demand Nereq and a lower engine speed limit Nemin to a target rotation speed Ne* of an engine (step S160). The engine speed demand Nereq represents a rotation speed of the engine at a specific drive point that ensures efficient output of an engine power demand Pe*. The lower engine speed limit Nemin represents a rotation speed of the engine at another specific drive point for a constant-speed drive of a hybrid vehicle at a current vehicle speed V. When the drive power demand Pv* is equal to 0, the control procedure of the invention cuts fuel supply to the engine and sets the lower engine speed limit Nemin to the target rotation speed Ne* of the engine (step S190). The engine is accordingly driven at the rotation speed of not lower than the lower engine speed limit Nemin and has a quick response to a demand for output power increase from the engine. This arrangement desirably reduces the loading of a battery and prevents premature deterioration of the battery.
摘要:
For the measurement of the voltage of each block which constitutes a battery pack with different timings, a voltage (V) and current (I) every block the current of which is measured at the same timing as the voltage is measured are read (S100-S108) and an inner resistance (R) is derived from the temperature (T) of the assembled battery (S110, S112). A value of the difference (IN−IN+1) of two currents corresponding to two voltages of respective blocks of a plurality of battery blocks multiplied by the inner resistance (R) of the battery pack is added to the difference (VN−VN+1) of two voltages to calculate the voltage difference ΔV (S116). When the maximum value ΔVmax of the calculated voltage difference ΔV exceeds the threshold value Vref, the state is judged to be an overdischarge (S122, S124, S128).
