Abstract

The invention discloses a blade electric vehicle driving range estimation method and device based on average energy consumption modeling. After an electric vehicle is powered on, the current battery state is detected; the initial driving range of the electric vehicle capable of traveling is estimated according to the current battery state and rated average energy consumption; and the remaining driving range is estimated according to the air conditioner use state and the traveled driving range. Therefore, by the adoption of the method and device, the driving range can be increased, the use convenience of the electric vehicle is improved, and accurate vehicle information can be supplied to a driver.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method and device for estimating the mileage of pure electric vehicles based on average energy consumption modeling. Background technique [0002] With the increase in the number of traditional fuel vehicles, the environmental pollution caused by fuel vehicles and the problem of global fuel depletion are also becoming more and more serious. Due to the advantages of environmental protection and energy saving, electric vehicles have attracted more and more attention, but because of their limited driving range, they have been widely promoted. [0003] However, the current estimation method for the mileage of electric vehicles is very imperfect, and it is easy to cause inaccurate mileage due to calculation errors, so that accurate mileage information cannot be provided. Contents of the invention [0004] In view of this, the object of the present invention is to propos...
