Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A vehicle comprising: a power storage device that is chargeable with electric power supplied from an external power supply provided outside the vehicle; a cooling device that cools the power storage device; and a controller that controls a charging operation for the power storage device such that the power storage device is charged under a charging condition of a constant current or a constant power over a charging period from start of charging to satisfaction of a completion condition, wherein the controller sets the charging condition such that a temperature of the power storage device when the completion condition is satisfied becomes an upper limit temperature, based on an amount of heat generation in the power storage device caused by charging and an amount of cooling of the power storage device by the cooling device, the vehicle has a plurality of charging modes selectable by a user of the vehicle, the plurality of charging modes including a first mode and a second mode, and when the first mode is selected by the user, the controller sets the constant current or the constant power and the upper limit temperature to be lower compared to when the second mode is selected by the user, wherein the cooling device performs an air-conditioning operation for a vehicle cabin of the vehicle, in addition to cooling of the power storage device, and the controller calculates the amount of cooling of the power storage device to be larger, thereby setting the constant current or the constant power to be larger, when the air-conditioning operation by the cooling device is not performed than when the air-conditioning operation by the cooling device is performed.
