20090248204 | Cooling system and control method of cooling system - The position of a damper is changed over to switch over the cooling mode between an inside air intake mode and an A/C intake mode. In the inside air intake mode, the air inside a passenger compartment of a motor vehicle is taken in and directly blown to a battery by the operation of a battery blower fan. In the A/C intake mode, the air cooled down by an air conditioner (evaporator) is taken in and blown to the battery by the operation of the battery blower fan. When the detected vehicle speed V is not lower than a preset reference speed Vref, the position of the damper is immediately changed over (steps S | 10-01-2009 |
20090266631 | Charge/Discharge Control Device and Charge/Discharge Control Method for Power Storage Device, and Electric-Powered Vehicle - 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 | 10-29-2009 |
20100155162 | COOLING SYSTEM, VEHICLE EQUIPPED WITH THE COOLING SYSTEM, AND METHOD FOR CONTROLLING THE COOLING SYSTEM - 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. | 06-24-2010 |
20100241308 | COOLING SYSTEM, MOTOR VEHICLE EQUIPPED WITH COOLING SYSTEM, AND CONTROL METHOD OF COOLING SYSTEM - A cooling system of the invention mounted on a motor vehicle has a damper configured to switch over an air blow mode between an inside air intake mode of taking in the air from a passenger compartment of the motor vehicle via operation of a battery blower fan and directly blowing the intake air to a battery and an A/C intake mode of taking in the air cooled down by an air conditioner (evaporator) via operation of the battery blower fan and blowing the cooled intake air to the battery. In response to a switchover demand of the air blow mode, when a vehicle speed is not lower than a preset reference speed, a switchover of the damper is immediately performed to switch over the air blow mode. When the vehicle speed is lower than the preset reference speed, the switchover of the damper is prohibited to keep the air blow mode unchanged. At the higher vehicle speed, the drive-related noise (background noise) sufficiently masks the wind noise occurring in the course of the switchover of the damper. The damper is thus switched over only at the vehicle speed of not lower than the preset reference speed. This arrangement effectively prevents the driver and the other passengers from feeling odd and uncomfortable. | 09-23-2010 |
20100241376 | CONTROL APPARATUS AND CONTROL METHOD FOR SECONDARY BATTERY - 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). | 09-23-2010 |

20120299537 | CHARGING CONTROL METHOD FOR SECONDARY BATTERY AND CONTROL DEVICE - The disclosed device for controlling charging of a secondary battery includes a step for calculating an amount of heat generated by a secondary battery on the basis of an inter-electrode-plate voltage, internal resistance, a current value, and charging efficiency; a step for calculating an amount of allowable generated heat of the secondary battery on the basis of a temperature of the secondary battery and the cooling ability of a cooling means that cools the secondary battery; and a step for limiting the charging power of the secondary battery when the aforementioned amount of heat generated is greater than the aforementioned amount of allowable heat generation. | 11-29-2012 |
20140028032 | HYBRID VEHICLE AND OUTPUT CONTROL METHOD OF VEHICLE-MOUNTED POWER STORAGE DEVICE - When electric power exceeding output allowable power at an engine startup time is output from a power storage device, deviated from a predetermined period of time during which the output allowable power of the power storage device is switched, an ECU suppresses increase of the output allowable power for the next startup time of the engine. Specifically, the ECU modifies the output allowable power for the next startup time of the engine from a first value to a second value lower than the first value, based on a period of time before deviation is eliminated. | 01-30-2014 |

20140335771 | COOLING DEVICE FOR POWER STORAGE DEVICE AND COOLING CONTROL METHOD FOR POWER STORAGE DEVICE - 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. | 11-13-2014 |
