1. A charging control apparatus comprising:
a proximity detection port to which a proximity signal is input from a connector of a charging cable;
a first proximity detection interface configured to generate a first proximity detection signal based on the proximity signal;
a relay disposed between the proximity detection port and the first proximity detection interface; and
a controller configured to:
determine the charging cable is connected to the connector of the proximity detection port and start a charging operation when the first proximity detection signal is greater than or equal to a predetermined voltage level, and
determine the charging cable is not connected to the connector of the proximity detection port when the first proximity detection signal is less than the predetermined voltage level,
wherein when the controller determines the charging cable is not connected, the controller is further configured to:
control the relay to directly relay the proximity signal to the controller,
determine a battery is short-circuited when the relayed proximity signal is greater than or equal to the predetermined voltage level, and
determine the charging cable is not connected to the connector of the proximity detection portion when the relayed proximity signal is less than the predetermined voltage level.
