20130162027 | CHARGE CONTROL APPARATUS FOR VEHICLE - When completion of timer charge before elapse of a designated time is designated by a timer charge reservation means for allowing a user to designate a predetermined charge time zone and a target amount of electric power to be charged to the battery, a timer charge start time is determined. Upon carrying out the timer charge, when it is predicted that the timer charge and battery heating are simultaneously carried out, a required amount of extension of a charge time period is determined so as to complete charge of the battery by the designated time, and starts charge of the battery at a time advanced relative to the timer charge start time by the required amount of extension of a charge time period. With this control, charge of the battery can be completed at a predetermined time without unnecessary enhancement in a required capacity of a battery heater. | 06-27-2013 |

20130288089 | BATTERY TEMPERATURE CONTROL DEVICE - Provided is a battery temperature control device configured to automatically heat a battery with a battery-driven heater so that the battery does not freeze at a minimum electric power consumption when the battery is out of use. The battery temperature control device predicts, based on a combination of a battery temperature and an outside air temperature, a predictive time that the battery temperature is likely to be less than a first set temperature, while the battery temperature is higher than or equal to the first set temperature at which there is no risk of freezing, and sets the predictive time as the next controller startup time, and determines whether or not the battery temperature has fallen to below the first set temperature with a control program wakeup when the predictive time has expired, and battery-drives the heater when the battery temperature fall has occurred, to heat the battery. | 10-31-2013 |

20150054449 | CHARGING DEVICE FOR STORAGE BATTERY, AND CHARGING METHOD FOR STORAGE BATTERY - A charging device for a storage battery includes: a charging power source for supplying electric power to a storage battery; a charging electric power detecting device adapted to detect electric power charged to the storage battery; a full charge determining device adapted to make a full charge determination based on a detected value of the charging electric power detecting device; and a charging controlling device adapted to conduct charging control by charging the storage battery until the full charge determination is made, stopping charging when the full charge determination is made, restarting charging after a prescribed time period elapses from the stop of charging, and continuing charging until the full charge determination is made again. The charging device further includes a temperature detecting device adapted to detect a temperature of the storage battery; and a stop time setting device adapted to set a stop time based on at least the temperature of the storage battery at the full charge determination. The stop time setting device sets the stop time to be longer as the detected temperature of the temperature detecting device becomes lower. | 02-26-2015 |
20150134282 | BATTERY RESIDUAL CAPACITANCE CALCULATION DEVICE AND BATTERY RESIDUAL CAPACITANCE CALCULATION METHOD - A residual capacity calculation apparatus for a battery includes: a current detection device to detect a charge/discharge current of the battery; a voltage detection device to detect a terminal voltage of the battery; a first residual capacity calculation unit to calculate a first residual capacity based on an integrated value of the charge/discharge current of the battery; a second residual capacity calculation unit to calculate a second residual capacity based on an open circuit voltage of the battery; a blend rate setting unit to determine a blend rate of the second residual capacity based on a deviation between the first residual capacity and the second residual capacity; and a third residual capacity calculation unit to calculate a post-combination residual capacity by subjecting the first residual capacity and the second residual capacity to weighted combination with use of the blend rate, in which the blend rate setting unit is configured to increase the blend rate as the deviation between the first residual capacity and the second residual capacity increases. | 05-14-2015 |
