Abstract

The invention discloses a method and a device for detecting available energy of an electrical vehicle and a battery of the electrical vehicle. The method for detecting the available energy of the battery of the electrical vehicle comprises the steps as follows: an available energy model of a complete vehicle battery system is obtained, wherein the available energy model is stored in the complete vehicle battery system in advance and is used for calculating the available energy of the complete vehicle battery system of the electrical vehicle; input of the available energy model is an influencing parameter of the battery energy; and output of the available energy model is the available energy of the battery of the electrical vehicle; the influencing parameter of the battery energy in the complete vehicle battery system is detected; and the available energy of the complete vehicle battery system of the electrical vehicle is calculated according to the detected influencing parameter and the available energy model. Through the method and the device, the accuracy of calculating the available energy of the battery of the electrical vehicle is improved.

Description

Technical field [0001] The present invention relates to the field of electric vehicles, in particular to a method and device for detecting available energy of an electric vehicle and its battery. Background technique [0002] The number of automobiles in the world has risen sharply, resulting in increasing demand for energy and increasing environmental pollution. In this context, electric vehicles have developed rapidly. Batteries are the power source of electric vehicles and the core components of electric vehicles. Accurate estimation of the battery's state of charge can not only improve the user experience of customers but also contribute to the safe operation of electric vehicles, which is very important for the development of electric vehicles. [0003] The current research on the battery state is mainly focused on the state of charge, and there is less on the nuclear energy state of the battery. Batteries are the power source for electric vehicles to perform external work, ...
