Abstract
A system for diagnosing a battery connection status includes: a DC-DC converter that converts and outputs a level of an input voltage; a battery connected to an output terminal of the DC-DC converter; and a controller that generates a control value for compensating for an error between a voltage command or a current command of the battery and a detection voltage or a detection current of the battery, controls the output of the DC-DC converter by applying the control value, and diagnoses a connection status between the DC-DC converter and the battery based on a change in error between the detection voltage or the detection current of the battery and the voltage command or the current command of the battery.
