System and method of performing a range estimation for hybrid and electric vehicles

A system for performing an automated range estimation process for an electric vehicle using a processor, comprising:

• a range estimator configured to:
• retrieve an initial value of an energy required to travel a unit distance for the electric vehicle that is either provided by a manufacturer of the electric vehicle;
• generate a first estimation model based on a correlation between a maximum all-electric-range and the energy required to travel a unit distance for the electric vehicle, the maximum all-electric-range defined as a maximum driving range based on the initial value of the energy required to travel a unit distance for the electric vehicle when an energy supply of the electric vehicle is at 100% state of charge as initially determined, and the energy required to travel a unit distance being calibratable based on a a maximum rechargeable capacity of the energy supply;
• adjust the first estimation model based on one or more predetermined driving conditions:
• update the maximum all-electric-range of the electric vehicle based on the adjusted first estimation model;
• calculate an estimated range of the electric vehicle based on the updated maximum all-electric-range of the electric vehicle and a fraction of total energy capability remaining in the energy supply of the electric vehicle;
• output the estimated range of the electric vehicle;
• and control the electric vehicle using the outputted estimated range.

One or more non-transitory computer-readable media having computer-executable instructions embodied thereon, the computer-executable instructions configured to cause at least one processor, upon being executed by the at least one processor, to perform a method of performing an automated range estimation process for an electric vehicle, the method comprising:

• retrieving, using the at least one processor, an initial value of an energy required to travel a unit distance for the electric vehicle that is either provided by a manufacturer of the electric vehicle;
• generating, using the at least one processor, a first estimation model based on a correlation between a maximum all-electric-range and the energy required to travel a unit distance for the electric vehicle, the maximum all-electric-range defined as a maximum driving range based on the initial value of the energy required to travel a unit distance for the electric vehicle when an energy supply of the electric vehicle is at 100% state of charge as initially determined, and the energy required to travel a unit distance being calibratable based on a a maximum rechargeable capacity of the energy supply;
• adjusting, using the at least one processor, the first estimation model based on one or more predetermined driving conditions;
• updating, using the at least one processor, the maximum all-electric-range of the electric vehicle based on the adjusted first estimation model;
• calculating, using the at least one processor, an estimated range of the electric vehicle based on the updated maximum all-electric-range of the electric vehicle and a fraction of total energy capability remaining in the energy supply of the electric vehicle;
• and outputting, using the at least one processor, the estimated range of the electric vehicle;
• and controlling, using the at least one processor, the electric vehicle using the outputted estimated range.
