  • Patent number: 10505238
    Abstract: A cooling system includes a cooling fan that blows cooled air to a main battery and a temperature sensor. When the temperature of the main battery is equal to or higher than a first predetermined temperature after start up of an electric drive vehicle, the cooling fan is driven with a constant command value for a predetermined time period and detection process of abnormal condition is performed for detecting presence or absence of abnormal condition of the cooling fan based on an actual rotation speed of the cooling fan. When the start up of the electric drive vehicle is based on an external charging operation of the secondary battery, driving of the cooling fan with the constant command value is inhibited. This structure ensures sufficient opportunities for detecting presence or absence of abnormal condition of the cooling fan.
