Electric driving range calculator

摘要

A method of and device for determining driving range for a vehicle operating with a rechargeable energy storage supply. The method includes performing a calculation based on a limited number of input parameters, including a driving distance, average speed, location and time of day. Other determinations, such as the possibility of using a battery power-depleting climate control system, as well as battery capacity and climate data for various seasonal and location factors may also be used in the calculations.

主权项

1. A method for determining a driving range of an electric-powered vehicle, the method comprising:
receiving, via a user input, segment distance, average speed into a driving range calculator; receiving location and time of day from position indicating equipment; calculating a value of at least one of an energy required to travel based upon the segment distance and average speed, driving time required to go a specified portion of the segment distance and energy required to go the specified portion, wherein the energy required to go the specified portion corresponds to that energy used by a climate control system over the specified portion of the segment distance; retrieving climate data relating to each season for the location from stored data; calculating an amount of energy used by a climate control system over the segment distance using the time of day, location, and the climate data; determining whether the segment distance can be completed based on the calculated values and calculated energy used by the climate control system; and outputting the driving range in a sensory-compatible format.
