  • Patent number: 10408689
    Abstract: An apparatus and method are provided for controlling a high voltage battery within vehicle. The apparatus monitors states of a first temperature sensor and a second temperature sensor mounted within a battery pack and calculates a replacement temperature that corresponds to the faulty temperature sensor using a temperature deviation within the battery pack for each ambient temperature of the battery when a faulty temperature sensor of the first temperature sensor and the second temperature sensor is detected. The replacement temperature is then used to operate the battery, and thus the stability of the battery control is improved even though the temperature sensor of the battery fails.
