Abstract: An apparatus and a method of diagnosing a current sensor of an eco-friendly vehicle is provided. A fault is detected in a current range between disconnection and short-circuit of a current sensor by monitoring whether a load using a high voltage in the eco-friendly vehicle is operated to detect a fault of the current sensor sensing an output current of a high voltage battery. The apparatus includes the current sensor configured to sense an output current of a high voltage battery and a load monitor that monitors whether a load in the eco-friendly vehicle is operated. A controller then detects an abnormality in the current sensor when the current sensor senses a current exceeding a first threshold value and the load is not operated.

Abstract: A system for charging a vehicle battery includes a relay configured to establish/interrupt electrical connection between the vehicle battery and a vehicle system supplied with power from the vehicle battery, and a controller. The controller is configured to monitor a voltage of the battery, control the relay to interrupt the electrical connection when a voltage of the battery is less than or equal to a first predetermined reference value, and control the relay to establish the electrical connection when a predetermined condition is satisfied while the relay is electrically disconnected. The controller controls the relay to be electrically connected to charge the battery through an external power source while the electrical connection is interrupted, and then control a connection state of the relay based on the voltage of the battery, a voltage and current of the relay at a side of the vehicle system, and whether a vehicle is started.
