Disclosed herein are a contactless power transmitting system having an overheat protection function, which protects a battery cell module from damage due to overheating while the battery cell module is being charged, and a method thereof. In the contactless power transmitting system, a contactless power transmitting apparatus transmits a first power to a contactless power receiving apparatus through a power transmitting coil to charge the battery cell module with the first power, and transmits a second power, of lower wattage than the first power, to the contactless power receiving apparatus through the power transmitting coil to charge the battery cell module with the second power if an overheat alarm signal is received from the contactless power receiving apparatus, thereby making it possible to fully charge the battery cell module while preventing overheating of the battery cell module.
