<p>The present invention relates to a method for diagnosing failure of an output impedance of a power supply apparatus for an eco-friendly vehicle, and relates to a method for diagnosing failure of an output impedance of a power supply apparatus for an eco-friendly vehicle, which is capable of preventing an auxiliary battery from being discharged, by performing an impedance failure diagnosis by estimating the output impedance of the power supply apparatus. That is, the present invention is to provide the method for diagnosing the failure of the output impedance of the power supply apparatus for the eco-friendly vehicle, which estimates an output impedance of a DC/DC converter, is capable of preventing an exchange error and the like of the auxiliary battery through impedance failure diagnosis logic to determine that an impedance has an error when an estimated impedance exceeds a standard value, and is capable of exact maintenance such as a change of a cable leading to an impedance increase, and the like.</p> |
