Estimation method for endurance mileage of electric vehicle

Abstract

The invention discloses an estimation method for endurance mileage of an electric vehicle, which comprises the following steps: 1, collecting battery electric quantity, consumed in the corresponding path, of the electric vehicle, and counting in advance to acquire data of the battery electric quantity averagely consumed by each path; 2, acquiring a running path from the current position to the destination position through a navigation system, and acquiring data of the battery electric quantity needing to be consumed according to the data of the battery electric quantity averagely consumed by each path; 3, comparing the data of the current battery electric quantity of the electric vehicle with the data of the battery electric quantity needing to be consumed; and 4, under the condition that the data of the current battery electric quantity of the electric vehicle is greater than the data of the battery electric quantity needing to be consumed, enabling the electric vehicle to prompt the data of the surplus electric quantity after arrival; under the condition that the data of the current battery electric quantity of the electric vehicle is less than the data of the battery electric quantity needing to be consumed, enabling the electric vehicle to prompt the position information that the electric vehicle can arrive in the running path; and under the condition that the data of the current battery electric quantity of the electric vehicle is equal to the data of the battery electric quantity needing to be consumed, enabling the electric vehicle to prompt that the surplus electric quantity is 0 after arrival. The estimation method overcomes the problem of very poor accuracy of an endurance mileage estimation result in the prior art and realizes accurate prediction of the endurance mileage.

Description

technical field [0001] The invention relates to the field of estimating the cruising range of an electric vehicle, in particular to a method for estimating the cruising range of an electric vehicle. Background technique [0002] With the development of the automobile industry, the development direction of intelligent and energy-saving automobiles is becoming more and more obvious. More and more people are buying electric vehicles. However, due to the limitations of current battery energy storage technology, the mileage of electric vehicles on the market is generally only about 100 to 200 kilometers per charge. In addition, public charging facilities are not perfect. Worried about whether there will be no electricity and whether there is a place to charge, which is the so-called "mileage anxiety" problem. The inaccurate estimation of battery life has greatly exacerbated this anxiety. [0003] At present, the estimation of cruising range on electric vehicles basically adopt...
