Abstract: When an ECU determines that a gas concentration within a battery pack is increasing, the ECU performs processing including: obtaining positional information; obtaining an amount of insolation; and performing gas exhaust processing when the ECU determines that a vehicle is traveling, determines that the position of the vehicle is a position where there is no cover above the vehicle, and determines that the position of the vehicle is a position where exhaust has no influence.

Abstract: A battery system includes a control device. The control device is configured to perform a first control and a second control. The first control includes placing an all-solid-state battery in an over-discharge state. The second control includes pressurizing the all-solid-state battery in the over-discharge state. The all-solid-state battery includes an anode layer, a solid electrolyte layer, and a cathode layer, in this order. The cathode layer includes silicon grains. The silicon grains include a clathrate II crystalline phase.

Abstract: The electrified vehicle includes an all-solid-state battery in which a positive electrode layer, a solid electrolyte layer, and a negative electrode layer are stacked in the front-rear direction (predetermined direction) of the electrified vehicle. The electrified vehicle also includes an acceleration sensor that detects a first acceleration in a direction perpendicular to the longitudinal direction and a second acceleration in the longitudinal direction. In an electrified vehicle, charging and discharging of the all-solid-state battery is prohibited when the first acceleration exceeds the first reference value, and the all-solid-state battery is prohibited until the second acceleration exceeds a second reference value that is larger than the first reference value, charging/discharging is allowed.

Abstract: A monitoring device for a battery that supplies electric power to a traction motor of a vehicle includes a sensor that detects a voltage of a battery cell of the battery, and a processing circuit that executes abnormality detection processing for detecting an abnormality in the battery, based on a detected voltage value that is detected by the sensor. The processing circuit executes processing for identifying a first elapsed time from a main switch of the vehicle being turned off until charging or discharging is started between the battery and predetermined on-board equipment, processing for identifying a second elapsed time from starting of the charging or discharging between the battery and the on-board equipment to a current point in time, and the abnormality detection processing when a total time of the first elapsed time and the second elapsed time reaches a predetermined threshold value.

Abstract: When an output of a braking force to a driving shaft is needed, and a needed braking force can be output by regenerative drive of the second motor, the engine self-sustainably operates, the regenerative drive of the second motor is performed to cause the second motor to output the needed braking force to the driving shaft. When the needed braking force cannot be output by the regenerative drive of the second motor, the needed braking force is output to the driving shaft by the regenerative drive of the second motor and motoring of the engine that performs fuel cut using the first motor. When a filter regeneration condition is established, an allowable input electric power is set to be lower than that of when the filter regeneration condition is not established.
