    Abstract: A vehicle includes a controller. When a brake operation amount has increased, the controller calculates an estimated input value at the time when a main battery is charged in response to an increase in the brake operation amount, on the basis of a current speed and an amount of increase in brake operation amount. The controller discharges the main battery for charging an auxiliary battery at a current value that is calculated on the basis of the estimated input value by controlling an operation of a DC-DC converter before charging the main battery in response to an increase in the brake operation amount. Thus, it is possible to cancel a bias of salt concentration that is developed during charging by a bias of salt concentration that is developed during discharging, so, after the main battery has been charged, it is possible to suppress development of a bias of the salt concentration and suppress an increase in the internal resistance value of the main battery.

    Abstract: In a method for charging a battery, the battery is a lithium ion battery including a graphite-containing negative electrode. A stage structure of the graphite is classified into a stage 1 to a stage 4 . The battery includes: an SOC region where the stage 4 and the stage 3 coexist; an SOC region where the stage 3 and the stage 2 coexist; and an SOC region where the stage 2 and the stage 1 coexist. The method includes first and second steps. The first step is estimating an SOC of the battery based on at least one of a voltage and a current of the battery. The second step is determining a charging current to the battery in accordance with the SOC of the battery such that the charging current in the SOC region is larger than the charging current in the SOC regions.

    Abstract: The present disclosure relates to an electric storage system including an electric storage device and an electronic control unit, and to a detection method of looseness in a fastening part thereof. The electronic control unit is configured to detect electric resistance between a first terminal and a second terminal that are present in a current path of the electric storage device. The electronic control unit is also configured to detect looseness of fastening in a fastening part that is present between the first terminal and the second terminal in the current path, when a periodic variation degree of the electric resistance (for example, the number of times that a variation amount of the electric resistance that is periodically acquired exceeds a threshold) is large.

    Abstract: A vehicle includes a generator, an engine, a main battery, an auxiliary battery, and a controller. The engine is configured to perform a load operation and a self-supported operation. The controller is configured to control charging and discharging of the auxiliary battery. When an upper limit of an allowable charging power of the main battery decreased and a command power is in a state in which the load operation and the self-supported operation are alternately switched, the controller is configured to operate a continuous charging. The continuous charging is to charge the auxiliary battery continuously for a predetermined time with a charging power. The charging power is a power which increases the command power to be equal to or larger than the threshold.
