Combined charging system for electric vehicle and control method of combined charging system for electric vehicle

Abstract

The invention discloses a combined charging system for an electric vehicle. The combined charging system comprises a battery management system a high-voltage distribution cabinet, a DC/DC converter, a power battery, a national standard charging socket, an European standard charging circuit and a lead acid battery power source formed by connecting two 12 V storage batteries in series. The battery management system is provided with a running wakeup terminal and a charging wakeup terminal. The national standard charging socket is provided with a wakeup line and a national standard connecting signal line. The wakeup line is electrically connected with the charging wakeup terminal. The national standard connecting signal line is connected with the battery management system. The European standard charging circuit comprises a stroke switch, a low-pressure replay, a PLC communication module and a European standard charging socket. The battery management system is electrically connected with the DC/DC converter, the PLC communication module and the national standard charging socket through a CAN bus. The combined charging system for the electric vehicle is convenient to use and good in charging effect.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an electric vehicle combined charging system and a control method thereof. Background technique [0002] At present, electric vehicles are becoming more and more popular, and electric vehicles have become a common means of transportation on the road. Because of their energy, environmental protection, low cost of use, and convenient and free driving, they are deeply favored by ordinary people. Conventional electric vehicles have to be charged after traveling a certain distance, otherwise they cannot continue to be used. Existing charging standards include Chinese standards and European standards, while electric vehicles in traditional technology usually only support one charging standard, which makes the use of electric vehicles regional and limited in scope. Contents of the invention [0003] In view of the technical problems in the background technology, the purpose of the p...
