Abstract

The invention discloses a DC charging pile field tester. A charging gun comprises a charging gun input interface and a charging gun output interface, the charging gun input interface is connected with the output interface of a charging pile to be tested, the charging gun output interface is externally connected with the input interface of the charging pile to be tested through a programmable load box. An ARM main control module is provided with a BMS simulation unit, and the BMS simulation unit is electrically connected to a battery simulator for generating and outputting a BMS simulation parameter signal. The battery simulator acquires the BMS simulation parameter signal and generates and outputs a simulation test power pulse based on the BMS simulation parameter signal. The DC charging pile field tester can simulate a full-process charging process such as BSM protocol and internal resistance change of an electric vehicle, monitor the charging status and calculate the power output, so as to realize the measurement and verification of the DC charging pile.

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...
