    Abstract: A secondary battery system includes an assembled battery that includes a plurality of blocks that are connected in series to one another. Each of the plurality of the blocks includes same number of cells that are connected in parallel to one another. A control device is configured to calculate an internal resistance ratio and a protection current. The internal resistance ratio is a value obtained by dividing the higher one of internal resistances by the lower one of the internal resistances of two of the plurality of the blocks. The protection current is a value obtained by multiplying the internal resistance ratio by a current value of the assembled battery detected by a current sensor. The control device is configured to perform the charge-discharge control based on the protection current.

    Abstract: In a vehicle that includes an engine, a motor, a generator, a battery electrically connected to the motor and the generator, and a transmission provided between the motor and an output shaft coupled to a drive wheel, an ECU executes "battery-less travel control" in which, at the time of a failure of the battery, the battery is isolated from the motor and the generator, the generator is caused to generate electric power by generating a torque, corresponding to an accelerator pedal operation amount (A), from the generator, and the vehicle is caused to travel by driving the motor using the electric power generated by the generator. The ECU suppresses losing a balance of input and output electric powers between the generator and the motor by filtering the accelerator pedal operation amount (A) (S25) when a vehicle speed (V) exceeds a limit vehicle speed (Vsh) (YES in S24) during the battery-less travel control (YES in S20).

    Abstract: In a hybrid vehicle including an engine, a motor, a generator, and a battery that is electrically connected to the motor and the generator, an ECU performs "battery-less travel control" enabling the vehicle to travel when a fault occurs in the battery by disconnecting the battery from an electrical system including the motor and the generator and driving the motor using power that is generated by the generator using the power of the engine. When the battery-less travel control is underway (YES in S20) and a vehicle speed V exceeds a vehicle speed limit Vsh (YES in S21), the ECU implements a vehicle speed limitation (S22). As a result, a control mode of the motor is less likely to shift to a rectangular control mode during the battery-less travel control.

    Abstract: In a hybrid vehicle of the invention, when a voltage level E of a low-voltage battery exceeds a preset alert reference value Eth1 (step S115), fueling control activates a negative pressure pump with a preset amount of power consumption for standard fuel vapor treatment (step S125). When the voltage level E of the low-voltage battery exceeds a low charge reference value Elow but is not higher than the preset alert reference value Eth1 (steps S115 and S120), the fueling control activates the negative pressure pump with a smaller amount of power consumption (step S130). When the voltage level E of the low-voltage battery is not higher than the low charge reference value Elow (step S120), the fueling control inactivates the negative pressure pump (step S135). Such control enables at least a voltage of the low charge reference value Elow to be reserved in the low-voltage battery even after regulation of internal pressure of a fuel tank.

    Abstract: A device and method for determining whether a malfunction is present in a drive circuit, which drives an electric device that generates counter-electromotive force, when all gates in the switching elements of the drive circuit are blocked. After the gates are blocked, the temperature of the switching elements is monitored and the presence of a malfunction is determined based on the detected temperature of the switching elements. A malfunction is determined to be present when the detected temperature equals or exceeds a predetermined temperature; the change in the detected temperature equals or exceeds a predetermined value; or the rate of change in the detected temperature equals or exceeds than a predetermined rate. Thus, it can be appropriately determined whether the gates in the drive circuit are appropriately blocked and minimize the influence of any malfunctions on other elements outside of the drive circuit.
