摘要： A system and a method for correcting a current value of a shunt resistor, which calculate a change amount of a resistance value by using a variable temperature value of a shunt resistor and calculate a real-time current value flowing in the corresponding shunt resistor based on the calculated change amount of the resistance value and voltage values of both terminals of the shunt resistor, so that even though the temperature value of the shunt resistor is continuously changed, an accurate current value may be obtained by reflecting all the changes.

摘要： A system and a method in which a contactor coil control unit, which applies an operation signal to a contactor coil (relay coil) that opens or connects contact points of a contactor (Relay), during a travelling of a vehicle applies an abnormal signal to the contactor coil by an external reason or a failure, the abnormal signal is detected in real time, so that it is possible to prevent the contact point of the contactor from being unintentionally opened by the abnormal signal, and it is possible to prevent an operating vehicle from being suddenly stopped by determining whether the vehicle actually travels based on a maintenance time of the abnormal signal and whether the abnormal signal is applied due to an actual failure of the contactor coil control unit.
