Abstract

The invention discloses a field tester for a DC charging pile. The charging gun includes a charging gun input interface and a charging gun output interface, the charging gun input interface is externally connected to the output interface of the charging pile to be verified, and the charging gun output interface is externally connected to the input interface of the charging pile to be verified through a program-controlled load box . The ARM main control module is provided with a BMS simulation unit, the BMS simulation unit is electrically connected to a battery simulator, and the BMS simulation unit is used to generate and output a BMS simulation parameter signal, and the battery simulator obtains the above-mentioned BMS simulation parameter signal and Generate and output simulated test electric energy pulses according to the above BMS simulated parameter signals. The field tester for DC charging piles of the present invention can simulate the whole process of charging such as the BSM protocol and internal resistance changes of electric vehicles, monitor the charging state and calculate the output of electric energy, and realize the measurement and verification of the DC charging piles.

Description

[0001] technical field [0002] The invention belongs to the technical field of DC charging piles, and in particular relates to a field tester for DC charging piles. Background technique [0003] As an important part of the national new energy strategy, electric vehicles are popularized very rapidly. The AC and DC charging piles supporting electric vehicles are being popularized simultaneously. According to survey statistics, there are few calibration devices for DC charging piles. Most of the existing DC charging pile calibration devices use the DC energy meter as a technical solution, but do not directly connect the calibration device as a simulation device to the charging circuit of the electric vehicle, and then convert the output of the detected target from the DC energy meter It is the energy output of the charging pile itself. [0004] For this reason, it is necessary to propose a new type of DC charging pile test equipment, which is convenient for transportat...
