Method and apparatus for monitoring the state of the battery of a hybrid electric vehicle

摘要

A system (40) for an automotive vehicle has a temperature sensor (90) generating a temperature signal indicative of the temperature outside the vehicle and a battery. A battery controller (54) is coupled to the temperature sensor (90) and the battery (64). The controller monitors a state of charge of the battery (64), monitors a temperature outside of the vehicle and compares the state of charge to a predetermined state of charge. The predetermined state of charge is a function of the temperature. The controller (54) generates an indicator when the state of charge reaches the predetermined state of charge.
