    摘要: A method for predicting the remaining travel distance of an electric vehicle. The method includes determining a useable battery energy value based on battery state-of-charge and battery capacity and a power value needed to heat or cool a vehicle cabin. The method determines an available battery energy value based on the useable battery energy value and an estimated energy value to provide the vehicle cabin heating or cooling, where the estimated energy value is determined using the power value. The method determines a recent energy used value based on an actual recent HVAC energy used value, a recent energy used value with no HVAC system loads and a recent energy used value with maximum HVAC system loads. The method determines a recent distance traveled value and determines the range by dividing the recent distance traveled value by the recent energy used value and multiplying by the available battery energy value.
