1. A device for managing batteries of a vehicle, the device comprising:
a plurality of temperature sensors mounted at different locations of the batteries; and
a controller configured to:
when a failure has occurred at a temperature sensor among the plurality of temperature sensors, estimate a temperature value at the failed temperature sensor based on data accumulated from operations of the batteries; and
control discharge of the batteries based on the estimated temperature value at the failed temperature sensor,
wherein the controller is configured to estimate the temperature value at the failed temperature sensor based on an average value of difference values between highest temperatures and lowest temperatures in respective periods of time.
