    Abstract: An estimation device configured to estimate a charge rate of a battery includes a voltage sensor configured to detect a voltage of the battery, a temperature sensor configured to detect a temperature of the battery, and a processing circuit. The processing circuit is connected to the voltage sensor and the temperature sensor and is configured to execute, while a vehicle is parked, an estimation process of estimating the charge rate of the battery based on a detection voltage and a detection temperature. The detection voltage is detected by the voltage sensor. The detection temperature is detected by the temperature sensor.

    Abstract: A battery system includes a chargeable and dischargeable secondary battery and a controller that estimates the deterioration state or the charge state of the secondary battery. When estimating the deterioration state or the charge state, the controller uses an average ion concentration between a positive electrode and a negative electrode. The average ion concentration varies depending on an electric current flowing through the secondary battery. The average ion concentration between the electrodes can be calculated with a computing expression that includes a surface pressure of the secondary battery as a variable. The surface pressure of the secondary battery can be detected by a pressure sensor. The surface pressure of the secondary battery can also be estimated from an electric current flowing through the secondary battery.

    Abstract: A positive electrode active material includes: a rich phase; a poor phase; and a two-phase coexistence phase in which the rich phase and the poor phase coexist. A method of managing a battery includes, in a many particle model in which the positive electrode active material is represented by a plurality of particles each distinguished by a particle number indicating a reaction sequence of the positive electrode active material, assuming that the charge carriers are equal in content among one or more particles belonging to each of the rich phase, the poor phase, and the two-phase coexistence phase: calculating an overvoltage of each of the particles for each of the phases; calculating a reaction current density based on the overvoltage for each of the phases; and estimating an SOC of the storage battery based on the reaction current density in each of the phases.

    Abstract: A ramp-equipped vehicle includes a ramp that is provided so as to be deployable from a side portion of a vehicle body to the outside of the vehicle body, a controller that controls the operation of deploying the ramp, and a sensor that senses moving bodies present in a certain area that is away from a ramp deployment area. The controller detects the moving bodies approaching the ramp deployment area and determines the moving velocities of the moving bodies based on the results of sensing by the sensor. The controller stops the operation of deploying the ramp when, after the start of the operation of deploying the ramp, it detects the approaching moving body having a moving velocity higher than or equal to a predetermined reference velocity with which the approaching moving bodies may reach the ramp deployment area during the operation of deploying the ramp.

    Abstract: A system for determining fixation of a relay has an electricity storage device, an electrical apparatus, a relay, a first insulation resistor, a second insulation resistor, a detection circuit, and a controller. When the relay is controlled to OFF, the controller determines, based on the voltage value detected by the detection circuit (the detected voltage value), whether or not the relay is fixed. When the detected voltage value is a voltage value that is obtained by dividing the reference voltage value by a combined resistance value and the reference resistance value, the controller determines that the relay is fixed. When the detected voltage value is a voltage value that is obtained by dividing the reference voltage value by the first resistance value and the reference resistance value, the controller determines that the relay is not fixed.

    Abstract: In vehicle platooning, when road surface information is received from a preceding vehicle, an ECU determines whether a specific spot on a road included in the road surface information can be avoided. That is, the ECU determines whether avoidance control can be performed. When it is determined that the avoidance control can be performed, the ECU transmits the road surface information received from the preceding vehicle to a following vehicle, and performs the avoidance control to avoid the specific spot on the road. In contrast, when it is determined that the avoidance control cannot be performed, the ECU ends a process without performing the avoidance control.
