Abstract: A hybrid car includes an engine, a first motor, a first driving shaft connected to a first drive wheel, a planetary gear, a second motor, a battery, and an electronic control unit. The electronic control unit is configured to control the first motor and the second motor such that the hybrid car travels within a range of allowable input and output electric power of the battery. The electronic control unit is configured to set an upper limit driving force based on a balancing driving force commensurate with a dynamic frictional force between the first drive wheel and a road surface and control the engine, the first motor, and the second motor when an idling-slip of the drive wheel occurs such that a driving force equal to or less than the upper limit driving force is output to the first drive wheel.

Abstract: An ECU executes a process including: acquiring a result of detection; determining whether a vehicle is being stopped; determining, when the vehicle is being stopped, whether an output value of a hydrogen sulfide sensor is a first threshold value or more; turning on a warning light when the output value is the first threshold value or more; determining, when the vehicle is not being stopped, whether the output value of the hydrogen sulfide sensor is a second threshold value or more; and turning on a warning light when the output value is the second threshold value or more.

Abstract: In a laminated all-solid-state battery, a negative electrode terminal and a positive electrode terminal around which a resin sheet is wound are sandwiched between exterior members (laminate films), and the exterior members are joined by heat welding. The laminated all-solid-state battery is in contact with the heat exchanger via a heat conductive sheet. When the terminal temperature detected by the temperature sensor provided at the negative electrode terminal and the positive electrode terminal is equal to or higher than a predetermined value, the flow rate control valve is fully closed and the flow rate control valve is fully opened. The cooling amount of the joint portion in which the negative electrode terminal and the positive electrode terminal extend increases, the temperature of the joint portion decreases, the deformation of the resin sheet is suppressed, and the unsealing of the seal is suppressed.

Abstract: A regeneration method of an all-solid-state battery includes a step of preparing an all-solid-state battery having a cathode that does not contain copper, and a step of executing overdischarge control of the all-solid-state battery. The overdischarge control is control of mitigating reaction variance that is variance in electrode reaction due to charging and discharging of the all-solid-state battery, by discharging the all-solid-state battery until a potential of the cathode becomes lower than an elution potential of copper.

Abstract: A vehicle includes a battery including an all-solid-state battery configured to be externally chargeable with electric power supplied from outside of the vehicle, a heater configured to heat the battery, and a control device configured to control the heater. The control device controls the heater such that when a predetermined condition related to the external charging is satisfied, the temperature of the battery during execution of the external charging is higher than when the predetermined condition is not satisfied. The predetermined condition includes a condition that an elevation of the vehicle during the execution of the external charging is higher than a predetermined height.

Abstract: There is provided a power supply system that is mounted on a vehicle and that comprises an accumulator connected with a power line via a system main relay including a precharge circuit; a smoothing capacitor mounted to the power line; and a power converter configured to use a DC power from the power line and supply an AC power to an electric load. When a precharge control that uses the precharge circuit to pre-charge the capacitor at a system start time fails in pre-charging the capacitor, the power supply system diagnoses a place of a failure, based on a change in common voltage of the accumulator during the precharge control.

Abstract: Vehicles include a main battery, an auxiliary battery, charging relays, a DC/DC converter, and an ECU. The charging relay is used to perform external charging for charging the main battery by the power equipment. The DC/DC converter is configured to step down the discharging power of the main battery and to provide the stepped-down power to the auxiliary battery. ECU controls the DC/DC converter. ECU lowers the charging state of the auxiliary battery from the first state to the second state by the end of the external charging, and drives the DC/DC converter after the end of the external charging.

Abstract: A battery system includes a battery unit, a heater unit, and a sensor unit. The battery unit is accommodated in a battery case and includes sulfide-based all-solid-state batteries. The heater unit is configured to heat the battery unit. The sensor unit is configured to measure a hydrogen sulfide gas concentration inside the battery case. The heater unit is started to be driven when a measured value of the sensor unit becomes greater than the first threshold value. After starting the driving of the heater unit, when the measured value becomes greater than the second threshold value that is higher than the first threshold value, a responsive control is executed to deal with generation of the hydrogen sulfide gas from the sulfide-based all-solid-state batteries.
