Abstract: An air conditioning system that can operate an air conditioner of an electric vehicle without interfering with the charging process, which utilizes a secondary battery. When operation of the vehicle is terminated and the control system determines that a frosting judgment decision is positive, the control system judges whether the charging current has dropped to a specified level or less. As soon as the charging current has dropped to or below the specified level, the excess charging current may be used for a defrosting operation. When the operation of the vehicle is stopped and the control system determines that a frosting judgment decision is negative, the control system judges whether a preliminary air conditioning switch is on. If the preliminary air conditioning switch is on, it is judged whether charging of the secondary battery is in progress. If charging is progressing, the control system determines whether the charging current has dropped to or below a specified level.

Abstract: The invention prevents the temperature of supplied air from being decreased by a defrosting operation when a vehicle is in operation. During the heating operation, it is judged whether the vehicle is in operation. When the vehicle is in operation, it is judged whether an external heat exchanger is frosted or not relying upon the external air temperature, temperature of the external heat exchanger (coolant) and the time of heating operation. When it is judged that frost is formed, the rotational speed of the compressor is increased to increase the ability to supplying the coolant, to maintain heating ability and to prevent the drop of temperature of the supplied air. When the frost is formed after the operation of the vehicle has been finished, it is judged whether the secondary batteries are being charged or not, i.e., whether the charging circuit of the secondary batteries is connected to the external power source for charging or not.
