The embodiment of the invention provides a battery type identifying method and device and a power system, and relates to the technical field of batteries. By means of the battery type identifying method and device and the power system, by receiving an attribute parameter signal sent by a rechargeable device, and then demodulating the attribute parameter signal to obtain a type identifying signal,the center frequency of the type identifying signal is obtained, when the difference value of the center frequency and the preset frequency is smaller than or equal to a preset threshold value, a mismatching signal is generated to remind that a charger of a user is not matched with the rechargeable device, the occurrence of a short circuit and the like is avoided, and the safety coefficient of thepower system is increased; meanwhile, since the attribute parameter signal is a photoelectric signal, an electric quantity signal or the type identifying signal or the like can be transmitted, the type identification of the rechargeable device is achieved without addition of a data transmission terminal to the rechargeable device, and thus the size of the rechargeable device can be easily reduced; meanwhile, the cost for manufacturing the rechargeable device is saved.
