A vehicle includes: a battery that is chargeable with electric power supplied from a charger provided outside the vehicle; and an air-conditioning and cooling system that cools the battery. An ECU controls a charging operation for the battery such that the battery is charged under a charging condition of a constant current which is constant over a charging period from start of charging to satisfaction of a completion condition. The ECU sets the charging condition such that a battery temperature when the completion condition is satisfied becomes an upper limit temperature, based on an amount of heat generation in the battery caused by charging and an amount of cooling of the battery by the air-conditioning and cooling system.

Vehicle and method for controlling vehicle

An exhaust gas control apparatus for an internal combustion engine includes a NOstorage reduction catalyst, a selective catalytic reduction catalyst, and an electronic control unit configured to shift an operation state of the engine from a rich operation state to a lean operation state, in a case where an acquired temperature of the NOstorage reduction catalyst is higher than a storage limit temperature, and an acquired NHadsorption amount is equal to or larger than a lower limit adsorption amount when a lean operation restart request is made, and not to shift the operation state from the rich operation state to the lean operation state in a case where the acquired temperature of the NOstorage reduction catalyst is higher than the storage limit temperature and the acquired NHadsorption amount is smaller than the lower limit adsorption amount when the lean operation restart request is made.

Exhaust gas control apparatus for internal combustion engine

An exhaust purification system of an internal combustion engine includes a catalyst arranged in an exhaust passage of the internal combustion engine, a fuel supply device supplying fuel to the catalyst through the exhaust passage, and a control device configured to control the supply of fuel by the fuel supply device. The control device is configured to calculate a concentration in exhaust gas of fuel supplied to the exhaust passage by the fuel supply device and a saturation vapor pressure concentration of the fuel and supply fuel from the fuel supply device to the catalyst only when the concentration in the exhaust gas is higher than the saturation vapor pressure concentration.

Exhaust purification system of internal combustion engine

In order to supply a reducing agent to an NOx catalyst in an appropriate manner when the temperature of the NOx catalyst is high, in cases where the temperature of the NOx catalyst is equal to or higher than a predetermined temperature at which ammonia is oxidized, and in cases where an NOx reduction rate in the NOx catalyst is smaller than a predetermined lower limit reduction rate, when the addition of the additive agent is carried out at least twice by changing an equivalent ratio with respect to an amount of NOx flowing into the NOx catalyst, the equivalent ratio in equivalent ratio control is made larger in the case where an amount of change of an amount of reduction of NOx accompanying a change of the equivalent ratio is larger than an amount of change of an amount of oxidation of ammonia accompanying the change of the equivalent ratio, than in the case where it is smaller than that.
