A vehicle battery charger for providing a charging current to a rechargeable vehicle battery which stores electric traction power includes a relay for interrupting the charging current, and fault diagnosing means for switching an operating condition of the relay to thereby diagnose a fault in the relay. At a time of starting and/or stopping a supply of the charging current, if a given condition is satisfied, the fault diagnosing means executes a diagnosis of the fault, or if the given condition is not satisfied, the fault diagnosing means does not execute a diagnosis of the fault.
