Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] method embodiment

[0028] The invention is mainly aimed at the charging management part of pure electric vehicles. According to the needs of customers in different time periods, the battery management system can intelligently identify the charging mode currently required by the electric vehicle according to the external characteristic parameters of the battery, the charging interval of the electric vehicle, and the ambient temperature. intelligent control. The external characteristic parameters of the battery mainly include the initial temperature and process temperature rise of the battery. In the electric vehicle charging control method provided by the present invention, first, the time t2 when the electric vehicle needs to be charged is recorded; then, the electric vehicle is charged in the fast charging mode or the slow charging mode, and the con...

Abstract

The invention relates to an electric automobile charging control method and device. Firstly, the moment t2 when an electric automobile needs to be charged is recorded; then, the electric automobile is charged in a quick charging mode or a slow charging mode, wherein the quick charging selection condition includes that the electric automobile is in an operation period, and the slow charging selection condition includes that the electric automobile is in a non-operation period; whether the electric automobile is in the operation period or not is judged according to the moment t2; and the charging current in the quick charging mode is larger than that in the slow charging mode. The quick charging mode is started so that power can be supplemented to the automobile within a short time, the automobile operation requirement and the actual requirement are met, energy and charging time are saved to the maximum extent, the long-time operation is guaranteed, and benefits are maximized; and the slow charging mode is adopted at night when the electric automobile does not work, and due to the fact that the electric charge at night is low, the charging cost can be effectively reduced through the slow charging mode. Therefore, the charging requirement of the electric automobile in different time periods can be met through the intelligent charging modes.

Description

technical field [0001] The invention relates to an electric vehicle charging control method and an electric vehicle charging control device, belonging to the field of electric vehicle charging management. Background technique [0002] Automobile is an important means of transportation in modern society, and it is also an important pillar industry of the national economy. With the continuous and rapid development of my country's economy and the acceleration of urbanization, the demand for automobiles will continue to grow for a long period of time in the future. In the process of industrialization and development in various countries in the world, the fossil energy on the earth is continuously decreasing, greenhouse gases are increasing, and the living environment of human beings is also deteriorating. As a result, governments of various countries have introduced stimulus policies to encourage the development of energy-saving and emission-reducing products. Although traditi...
