Abstract:
1. An in-vehicle charge and discharge control apparatus in a vehicle having a battery to supply an electric power to an electronic apparatus in the vehicle, the battery accumulating an electric power which a motor in the vehicle generates by regeneration during deceleration of the vehicle, the in-vehicle charge and discharge control apparatus comprising: a battery temperature control device to execute a cooling control when a battery temperature is equal to or greater than a battery upper limit temperature, an estimate device to estimate a temperature increase of the battery in an estimate road range, which the vehicle is estimated to travel, based on an estimate of energy acquirable by regeneration in the estimate road range; a temperature designation device to designate as a special value of the battery upper limit temperature a temperature obtained by subtracting the temperature increase from a default value of the battery upper limit temperature; a road range designation device to designate a road range just prior to the estimate road range as a battery upper limit temperature reduction road range; and a change device to cause the battery temperature control device to execute a battery upper limit temperature changeover control that
