摘要:
A battery system includes an electricity storage device (70) including a plurality of battery units (BU). The electronic control device (100) is configured to be capable of switching a travel mode of the vehicle between a CD mode and a CS mode. The electronic control device (100) is configured to calculate a vehicle state of charge at a higher value (SOC (A)) than an average state of charge (Smid) when the average state of charge (Smid) is higher than a threshold value (D), and calculate the vehicle state of charge at a lower value (SOC (B)) than the average state of charge (Smid) when the average state of charge (Smid) is equal to or lower than the threshold value (D). The threshold value (D) is set at a lower value than a center value (C) between an upper limit value (A) and a lower limit value (B) of the vehicle state of charge.

When an abnormality except for a temperature abnormality of a travel-purpose battery 220 is detected (YES in S1100), a battery ECU 260 of the present invention renders a system main relay 640 OFF to make a change to a battery-less travel mode while using a battery cooling fan 220D to cool the travel-purpose battery 220 (S1200-S 1400). When a temperature abnormality of the travel-purpose battery 220 is still detected (YES in S1600), a system-off command signal is output (S 1700) to cause the hybrid vehicle to become unable to travel. In this way, limp home mode and system shutoff of the hybrid vehicle can be surely implemented even in the case where an abnormality occurs to the travel-purpose battery 220.

A hybrid ECU executes a program including the steps of: setting a fan driving level F for a cooling fan, as based on a high voltage battery's temperature TB, SOC and input and output currents, and a vehicular cabin's internal temperature and background noise (S100); detecting from a signal transmitted from a voltage sensor the voltage of an auxiliary battery serving as a power supply for the cooling fan (S102); and setting a duty command value for the cooling fan from fan driving level F and the auxiliary battery's voltage so that the duty command value is smaller as a voltage of the auxiliary battery is higher (S 104).

An electrical storage, system mounted on a vehicle includes: an electrical storage device that is charged or discharged; and a controller that calculates an SOC on the basis of a correspondence relationship between a voltage of the electrical storage device and an SOC of the electrical storage device and that calculates a full charge capacity of the electrical storage device on the basis of an SOC difference between before and after charging and an accumulated charging current value during charging.

摘要:
In a traveling mode for controlling traveling of a hybrid vehicle to maintain a charge amount (SOC) of a power storage device of the hybrid vehicle to fall within a predetermined control range, when a malfunction associated with the power storage device 10 takes place, a control center value SOCr# defining the control range is set higher than a control center value SOCr employed in a normal state and set at a value near a management lower limit value of the SOC. Then, it is permitted to charge/discharge the power storage device. In this way, upon occurrence of a malfunction of a level that does not require immediate interruption of the charging/discharging of the power storage device, a vehicle operation can be continued using the power storage device while protecting the power storage device.
