Device and method for intelligently forecasting continuous mileage of electric vehicle

Abstract

The invention provides a method for intelligently forecasting the continuous mileage of an electric vehicle. The method comprises the following steps: acquiring voltage signals, current signals and temperature signals respectively; detecting the residual electricity quantity according to an open-circuit voltage method and an ampere hour method; acquiring speed signals, and obtaining new riding kilometers per ampere hour in a manner of weighted calculation; and obtaining the specific value between the difference value of the residual electricity quantity of the electric vehicle and the consumed electricity quantity during the riding of the electric vehicle, and the new riding kilometers per ampere hour, obtained in the last step. According to the method disclosed by the invention, modeling analysis is performed by utilizing the combination of a fuzzy control theory as well as a microelectronic technique with voltage signals, current signals, battery capacity, temperature signals, speed signals, impedance loss signals, large-current compensation signals and the compensation for dad riding habits; the laws of mathematic and relevant engineering experiences are summarized, and a model algorithm in process acquisition is analyzed, so that a result is obtained. Through the adoption of the method, a complete innovative intelligent self-taught forecasting system of residual riding mileage for electric motors, electric motorcycles and the like is created.

Description

technical field [0001] The invention relates to the field of traffic devices powered by electric energy, in particular to a device and method for intelligently predicting the continuable mileage of an electric vehicle. Background technique [0002] Electric vehicles that are completely powered by batteries in our daily life, especially electric vehicles used by individuals for transportation, such as electric scooters for the elderly and disabled, electric wheelchairs, electric tourist vehicles, and suitable for enterprises The electric mopeds, bicycles, and motorcycles of employees of public institutions, civil servants, and urban residents do not have indicator devices for continuation mileage. Experience estimates that due to inaccurate estimates, it may happen that the energy of the battery has been exhausted before arriving at the scheduled location. If the parking place cannot be charged, the car can only stop, which brings trouble and helplessness to the cyclist, espe...
