Abstract

The invention discloses an electric vehicle charging control method. The method comprises the steps of receiving charging control command information, and determining the charging mode and the charging current control mode according to the charging control command information; obtaining charging stop SOC according to the charging mode, and determining charging current according to the charging current control mode; conducting charging control on a power supply unit and a power battery of an electric vehicle according to the charging stop SOC and the charging current. By the adoption of the method, the service life of the power battery can be prolonged. The invention further discloses an electric vehicle charging control system.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a charging control method and a charging control system of an electric vehicle. Background technique [0002] In the field of new energy vehicles and electric energy storage equipment, the recyclable life of power batteries will vary greatly at different charging depths. For example, if the power battery is often charged and discharged in the way of shallow charge and shallow discharge during use, the life of the power battery will be significantly extended, and the life of the power battery will be reduced sharply if it is charged and discharged with full charge and deep discharge. Furthermore, during the use of electric vehicles, there will be demand for long-distance travel and short-distance travel. Under the demand for short-distance travel, the power battery should meet the conditions of shallow charging and shallow discharge to maximize battery life. There...
