Claim Text:
1. An inside ventilation method of a vehicle, comprising: receiving, by a control unit, an operating signal from a smart key; sensing, by one or more temperature sensor, an inside temperature of the vehicle once the operating signal is transmitted to the control unit determining, by the control unit, whether the inside temperature deviates from a required temperature range; comparing, by the control unit, the inside temperature and a battery temperature when the inside temperature deviates from the required temperature range; controlling, by the control unit, a heating, ventilation, and air conditioning system (HVAC) and operation of a battery operated fan based upon the comparison of the inside temperature and the battery temperature; determining, by the control unit, whether the inside temperature of the vehicle is less than 20° C. when the inside temperature deviates from the required temperature; wherein when the control unit determines that the inside temperature is less than 20° C., the heater of the HVAC and the battery operated fan are controlled based on the comparison of the inside temperature and the battery temperature; and determining, by the control unit, whether the battery temperature is less than 0° C. when the inside temperature is less than the battery temperature, wherein when the control unit determines that the battery temperature is less than 0° C., the heater of the HVAC is turned on and the battery operated fan is turned off.
