Problems solved by technology

[0003] At present, most of the charging pile testing technologies in the market have testing equipment that uses resistive loads or batteries as charging piles. This technology cannot grasp the dynamic voltage and current test characteristics, and cannot constantly monitor parameters and other performance. This is very important for the functional experiment of charging piles. and batch detection efficiency is extremely inconvenient

Embodiment Construction

[0012] Below in conjunction with the drawings and specific embodiments, the present invention will be described in detail. Before describing the technical solutions of the various embodiments of the present invention in detail, the terms and terms involved will be explained. In this specification, the same name or the same number Components represent similar or identical structures and are for illustrative purposes only.

[0013] Such as figure 1 As shown, the charging pile test system includes an AC analog grid power supply 1, a charging pile 2, a BMS simulator 3, and a battery simulator 4 that are sequentially connected by signals. The platform 5 is connected to the DSP sampling control module 6, and the DC output in the charging pile test is fed back to the DC bus inside the AC analog grid power supply through the battery simulator, so as to achieve the purpose of energy internal circulation, and at the same time save the battery simulator. DC-AC architecture.

Abstract

The invention provides a charging pile test system. The system comprises an AC simulating grid power supply, a charging pile, a BMS simulator and a battery simulator in signal connection in order; theAC simulating grid power supply and the battery simulator are connected with a centralized control platform and a DSP sampling control module through CAN communication; the DC output in the chargingpile test is fed back to the AC simulating grid power supply through the battery simulator. The platform full-automatic detection can be realized, verification assessment test is implemented for the electric performance, the interface compatibility and security of the non-vehicle-mounted charger, and the efficiency for research and development functionality test or batch production detection of the pile enterprise is improved.

Description

technical field [0001] The invention relates to the technical field of circuit testing systems, in particular to a testing system for charging piles. Background technique [0002] In recent years, with the increase in the output of charging piles, how to quickly realize the certification and factory testing of charging piles has become one of the key technical issues considered by charging pile enterprises. [0003] Most of the charging pile testing technologies in the market currently use resistive loads or batteries as charging pile testing equipment. This technology cannot grasp the dynamic voltage and current test characteristics, and cannot constantly monitor parameters and other performance. This is very important for the functional experiment of charging piles. It is extremely inconvenient in terms of efficiency and batch detection. Contents of the invention [0004] In order to solve the problem of ex-factory performance testing of electric vehicle charging piles ...
