Embodiment 1

[0093] Embodiment 1, a conductive charging test method for AC charging:

[0094] Wherein, the step S120 further includes:

[0095] Step S150, make the electric vehicle for testing sleep, and the AC charging interoperability control module controls the relay switches S1, S2, S3, S4, S5, S6, and S7 in the first relay switch device to be disconnected, so that the conduction charging test system L1 (AC Power supply), N (neutral line), PE (grounding line), CC (charging connection confirmation), CP (charging control confirmation) are disconnected; after inserting the slow charging gun of the test system, the control system controls the first control switch K1, the sixth Close the relay switch S6, adjust the resistance board value of the test system CC loop to the corresponding specified value and boundary value (meeting Table A.3 in GB / T 18287.1-2015), respectively simulate the full connection of cable capacity 10A, 16A, 32A and 63A state, if the charging message is sent normally, ...

Embodiment 2

[0101] Embodiment 2, the conductive charging test method for DC charging:

[0102] Wherein, the step S121 further includes:

[0103] Step S160, the electric vehicle for testing is in sleep mode, the relay switches S8, S9, S10, S11, S12, S13, S14, S15, and S16 are controlled to be disconnected, and the relay switches S11, S12 are controlled after the fast charging gun of the fast charging conduction test system is inserted. Closed to provide 12V and 24V auxiliary power respectively. If the charging message is sent, the electric vehicle will be awakened and continue to the next step; otherwise, it is an abnormal state, and go to step S13;

[0104] Step S161, prepare the electric vehicle for testing, control the relay switches S8, S9, S10, S12, S13, S14, S15, and S16 to close, control the eleventh relay switch S11 to open, and start the test after inserting the fast charging gun of the test system system, if the detected voltage between DC+ and DC-, the current of DC+ and DC- lo...

Abstract

The invention provides a conductive charging simulation test system for an electric vehicle. The system comprises a whole vehicle charging simulation system and an electric vehicle for measurement, and is characterized in that the whole vehicle charging simulation system comprises a controllable alternating-current power supply, an alternating-current charging interoperation control module, a controllable direct-current power supply, a direct-current charging interoperation control module and an upper computer. The invention further provides a corresponding method. By implementing the embodiment of the invention, the charging process of simulating different types of alternating-current and direct-current charging equipment and the electric vehicle can be tested, the charging compatibilityand stability of the electric vehicle are improved, and charging faults are reduced, so that the conduction charging interoperability test of the electric vehicle is realized.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to a conductive charging test system and method for electric vehicles, which are used to simulate different types of AC and DC charging equipment and the charging process of electric vehicles for control testing. Background technique [0002] In recent years, with the continuous development and popularization of new energy electric vehicles, the infrastructure of charging equipment has been continuously improved. In order to solve the compatibility problem between charging piles and electric vehicles, and to promote the matching adaptability of vehicles and piles, the National Standards Committee issued the Electric Vehicle Five national standards including charging interface and communication protocol. However, in the actual process, due to different interpretations of the national standard, electric vehicles and some charging equipment often have charging incompa...
