Pure electric vehicle energy consumption monitoring optimization method and system

Abstract

The invention relates to a pure electric vehicle energy consumption monitoring optimization method, which comprises the steps of setting a target place where a vehicle needs to arrive, and starting tocollect vehicle operation information after the vehicle is started; determining an actual road condition from the target location to the location of the current vehicle, and simulating the actual road condition information; when the driving cycle number i is larger than or equal to 1, starting energy consumption evaluation; calculating and obtaining real-time energy consumption efficiency in thecurrent energy consumption evaluation period, and displaying the real-time energy consumption efficiency Ei and the energy consumption rate Ei-1 in the (i-1) th energy consumption evaluation period ona vehicle-mounted instrument; giving an optimization suggestion of the driving behavior; and through comparing the residual electric quantity of the battery with the residual demand electric quantity, giving a prompt of whether the driver can normally arrive at the target place. The invention further discloses a pure electric vehicle energy consumption monitoring and optimizing system. The current energy consumption condition can be accurately provided for the driver, suggestions can also be provided for the driving behavior of the driver, and energy conservation and consumption reduction ofthe whole vehicle are achieved.

Description

Technical field [0001] The invention relates to the technical field of electric vehicle monitoring and energy saving optimization, in particular to a pure electric vehicle energy consumption monitoring optimization method and system. Background technique [0002] With the gradual aggravation of the energy crisis and environmental pollution, electric vehicles, as a strategic industry, have attracted more and more attention for their use of clean energy. The economy of electric vehicles has always been the focus. Due to the bottleneck of the core battery technology and the complexity of the actual road conditions, the driver cannot have a good grasp of the real-time consumption of battery energy, so there is a general "continued" during driving. Driving mileage anxiety". [0003] In addition to complex actual road conditions, the driver’s own driving behavior will also increase energy consumption. For example, undesirable driving behaviors such as continuously high vehicle speeds an...

AI Technical Summary

Problems solved by technology

At present, most of the methods and systems for energy consumption monitoring and optimization of electric vehicles collect vehicle operation information for a period of time to evaluate energy consumption. This method cannot perform dynamic analysis based on the driver’s real-time driving habits, and the accuracy of monitoring and evaluation results is low. Low
