Abstract

The invention discloses a novel energy feedback testing and detection system of a quick charging pile of an electromobile. The system comprises an upper computer system, an alternating current distribution / variable frequency voltage regulator, a power analyzer, an energy power unit, a signal acquisition unit and a BMS (battery management system) simulator. The system is provided with the BMS simulator which can simulate real-time communication of a direct current charging pile in an automobile charging process and fault protection, so that the quality assurance of the direct current charging pile is improved; the system has an energy feedback function; a power module can return input direct-current energy to a power grid through a grid-connected inversion manner; the production cost is lowered; a higher quality detection platform is provided for a testing department; and the development of the electromobile and clean energy is promoted.

Description

Technical field [0001] The invention relates to a detection system, specifically a new energy feedback type electric vehicle fast charging pile testing and detection system. Background technique [0002] With the vigorous development of the new energy industry chain, the demand for fast charging piles for electric vehicles is increasing, and the testing requirements for charging piles have become more stringent. At present, the loads of the detection system of electric vehicle fast charging piles are all resistive loads. When performing factory inspection and aging test on the charging piles, the power consumption is large, the load is seriously heated, and it does not have the function of analog communication with the BMS. Based on the above problems, a new energy feedback type electric vehicle fast charging pile test and detection system is proposed. This detection system can simulate communication with the vehicle BMS, and has both power supply and load characteristics to...
