    摘要： A tractor includes: a work machine connected to a vehicle body; an elevator mechanism configured to move the work machine up and down; an electric motor; a battery; an electric leakage detection circuit configured to detect electric leakage in the battery; and a control device. The control device controls the elevator mechanism either in a lowered state or a raised state, the lowered state being a state where the work machine is placed at a position making contact with a ground, the raised state being a state where the work machine is placed at a position distanced from the ground. In a case where the electric leakage detection circuit detects electric leakage in the battery at the time when the elevator mechanism is in the lowered state, the control device performs a state change process of bringing the elevator mechanism into the raised state.

    摘要： An ECU performs processing including obtaining a full charge capacity when a cooling apparatus remains stopped, showing textual information that inquires about whether or not cooling can be carried out when a battery temperature is equal to or lower than a threshold value TB(1), when the full charge capacity is equal to or lower than a threshold value C(1), and when the battery temperature is equal to or higher than a threshold value TB(2), carrying out battery cooling control when a request for carrying out cooling has been issued, and maintaining a standstill state of the cooling apparatus when no request for carrying out cooling has been issued.

    摘要： 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 and a vehicle speed V exceeds a vehicle speed limit Vsh, the ECU implements a vehicle speed limitation. 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.

    摘要： An ECU sets a SOC estimated from an OCV at the time of activating a system of a vehicle as an initial SOC value in the case where the SOC during a stop of the system is higher than a first SOC, which represents the SOC estimated from the OCV at the time of activating the system by using a discharging curve line, or the SOC during the stop of the system is lower than a second SOC, which represents the SOC estimated from the OCV at the time of activating the system by using a charging curve line. The ECU sets the SOC during the stop of the system as the initial SOC value in the case where the SOC during the stop of the system is equal to or lower than the first SOC and is equal to or higher than the second SOC.
