Abstract
A device and a method for managing batteries of a vehicle are disclosed. The device may include: batteries arranged in a vehicle, a plurality of temperature sensors mounted at different locations of the batteries, and a controller that, when a failure occurs at an arbitrary temperature sensor among the plurality of temperature sensors, estimates a temperature value at the failed temperature sensor using big data, and controls discharge of the batteries based on the estimated temperature value.
Claims18
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.
A method for managing batteries of a vehicle including a plurality of temperature sensors mounted at different locations of the batteries, the method comprising:
- determining, by a controller, whether a failure has occurred at a temperature sensor among the plurality of temperature sensors;
- estimating, by the controller, a 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;
- and
- managing, by the controller, discharge of the batteries based on the estimated temperature value.
