A vehicle includes at least one processor, at least one memory, and a storage. The processor functions as a current-value acquirer that acquires a current value of a battery mounted on the vehicle, a current-value frequency distribution deriver that increments an acquisition count for one of classes, to which the current value belongs, and derives a current-value frequency distribution representing acquisition counts for the respective classes, and a current-value rate distribution deriver that transforms the acquisition counts to acquisition rates each indicating a rate of the each of the acquisition counts to a total of the acquisition counts and derives a current-value rate distribution representing the acquisition rates. The processor further functions as a traveling pattern rate deriver that derives on the basis of an actual current-value rate distribution and predetermined current-value rate distributions stored in the storage, traveling pattern rates indicating rates of the respective predetermined current-value rate distributions.

Vehicle

A vehicle includes a traveling motor, a traveling battery that drives at least one wheel, a low-voltage electric component, at least one processor, and a storage medium. The traveling battery includes battery modules each including battery cells and supplies electric power to the traveling motor. The low-voltage electric component operates at a voltage lower than an output voltage of the traveling battery. The storage medium stores a program to be executed by the processor. The program includes at least one command that causes the processor to perform a state-of-health (SOH) calculation process of calculating the SOH of the battery modules, and a selection process of selecting a low-voltage power feeder module from the battery modules based on the SOH calculated in the SOH calculation process. The low-voltage power feeder module corresponds to one of the battery modules to be used to supply electric power to the low-voltage electric component.

Vehicle system for battery module allocation

A vehicle control apparatus includes a control system. The control system includes a processor and a memory that are communicably coupled to each other, and executes a polarization eliminating mode in which polarization is eliminated by controlling an energization state of an electric power storage device while a vehicle is traveling. The control system sets a first necessary time to eliminate the polarization based on a polarization state of the electric power storage device, acquires a second necessary time to an arrival of the vehicle at a destination, permits the polarization eliminating mode to be executed while the vehicle is traveling in a case where the first necessary time is shorter than or equal to the second necessary time, and refrains from permitting the polarization eliminating mode to be executed while the vehicle is traveling in a case where the first necessary time is longer than the second necessary time.

Vehicle control apparatus

A charging control apparatus includes a battery, an electric charge mover, and a processor. The battery includes multiple cells. The electric charge mover is configured to move electric charge between the multiple cells. The processor is configured to, upon charging the battery, cause the electric charge mover to move the electric charge of one or more cells serving as a part of the multiple cells to another one or more cells of the multiple cells, and perform a partial charging that charges the one or more cells serving as the part of the multiple cells after causing the electric charge mover to move the electric charge.
