Abstract

A method and system for providing electric vehicle drive range optimization. Various vehicle data is collected from various sources and analyzed to derive vehicle parameters related to estimating a driving range of an electric vehicle, such as battery state of charge, an energy consumption rate, an efficiency factor, historical driving patterns, climate control usage, auxiliary accessory usage, etc. The vehicle parameters are analyzed to determine a vehicle driving state adjustment that changes a vehicle parameter that causes the estimated driving range to increase. Some example vehicle drive state adjustments may correspond to adjusting vehicle speed, adjusting a throttle map, reducing the auxiliary electrical load, and/or other adjustments to lower the energy consumption rate and/or increase one or more efficiency factors to extend the estimated driving range. The vehicle driving state adjustment may be implemented automatically or manually based on a determined implementation method.
