Online prediction method and device for remaining mileage of electric automobile

Abstract

The invention relates to an online prediction method and device for the remaining mileage of an electric automobile. The online prediction method comprises the steps of obtaining in-transit data and traveling environment data of the travelling electric automobile, calculating the unit mileage electricity consumption of the electric automobile under the current situation by means of the in-transit data, the travelling environment data and an electricity consumption speed data model, and predicting the remaining travelling mileage of the electric automobile according to the unit mileage electricity consumption. The online prediction device for the remaining mileage of the electric automobile is achieved based on the online prediction method. By adoption of the online prediction method and device for the remaining mileage of the electric automobile, a prediction result is more accurate, the problem that electricity is exhausted when the travelling mileage exceeds a travelling mileage expected by a user, and an automobile cannot continue to travel is avoided, and the user driving experience is improved.

Description

technical field [0001] The invention relates to the technical field of energy management, in particular to an online prediction method and device for the remaining mileage of an electric vehicle. Background technique [0002] Since the driving force of electric vehicles is supplied by batteries, their cruising range is limited, and it is very easy to break down due to power depletion. For this purpose, the electric vehicle's battery power and range need to be evaluated. When evaluating the cruising range of electric vehicles in the current technology, the SOC (state of charge evaluation) of the on-board battery is usually estimated first, and then the storage power of the vehicle is obtained, and then the remaining mileage is roughly estimated according to the average energy consumption level of the vehicle . This method is not accurate enough to calculate the power consumption of accessories, and can only estimate the current remaining mileage. Due to the fast consumptio...
