Device and method for optimizing cruising range of electric vehicles

Abstract

The invention discloses a device and method for optimizing the cruising range of an electric vehicle. The device includes a data acquisition system, a decision system and an expert system; the data acquisition system includes a mobile client, a vehicle communication system and a charging station communication module; the decision system includes a first wireless Communication module and decision-making module; the expert system includes a second wireless communication module, a database and a path planning module; the expert system retrieves the database after receiving the driving task attribute information, electric vehicle condition information, and charging pile working condition information, and returns a Group the existing planned route, otherwise it will be processed by the route planning module, in which the route planning module combines the constraints of electric vehicle conditions, charging pile conditions, traffic conditions, driving task attributes, etc. to establish an optimization problem model to solve the optimization problem , providing multiple battery-friendly routing schemes. The invention can effectively alleviate the problem of "mileage anxiety", greatly improve work efficiency, and has profound practical significance.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a device and method for optimizing the cruising range of an electric vehicle, in particular to a battery-friendly device and method for optimizing the cruising range of an electric vehicle. Background technique [0002] In recent years, with the depletion of fossil energy and serious environmental pollution, the research and development of new energy vehicles has become the only way to build a resource-saving and environment-friendly society. In this context, electric vehicles came into being. However, after years of development, electric vehicles have not yet entered thousands of households. This is because their inherent limitations have not been broken through: less energy storage, short mileage, slow charging, and need to use public charging devices for relay charging to ensure battery life. At present, researches on the optimization of the mileage of electric vehicles in ...
