The invention provides an apparatus and a method for diagnosing battery replacement for vehicles which may accurately diagnose whether a battery has been replaced using an internal resistance of the battery. The apparatus includes a measurer for measuring the internal resistance of the battery, a storage for storing the measured internal resistance, and a controller for diagnosing whether the battery has been replaced based on the internal resistance. The controller, when vehicle power is reset, controls the measurer to measure a first or second internal resistance after starting a vehicle, updates and stores the measured first or second internal resistance in the storage, compares a current first internal resistance value with a former first internal resistance value or a current second internal resistance value with a former second internal resistance value, and diagnoses that the battery has been replaced when the corresponding values differ from each other.

    本公开提供一种车辆电池更换诊断装置和方法,可以利用电池的内部电阻准确地诊断电池是否已经被更换。该装置包括:测量器,用于测量电池的内部电阻;存储器,用于存储所测量的内部电阻;以及控制器,用于基于内部电阻诊断电池是否已经被更换。当车辆电源被重置时,控制器控制测量器以在车辆启动之后测量第一内部电阻或第二内部电阻,更新并在存储器中存储所测量的第一内部电阻或第二内部电阻,将当前的第一内部电阻值与先前的第一内部电阻值进行比较或者将当前的第二内部电阻值与先前的第二内部电阻值进行比较,并且当对应的内部电阻值彼此不同时,诊断出电池已经被更换。
