Device for testing charging pile performance

Abstract

The invention discloses a device for testing charging pile performance, comprising an analog circuit system, a feature parameter detection circuit, an industrial personal computer monitor system and a humiture control case. The analog circuit system comprises a simulation power supply and a load circuit; the simulation power supply is connected with an input end of the charging pile; the load circuit is connected with an output end of the charging pile; the feature parameter detection circuit detects the feature parameters of the charging pile during a discharge process and sends the feature parameters to the industrial personal computer monitor system; the humiture control case controls the humiture of the surrounding environment of the charging pile during the discharge process; the humiture control case comprises a case body, a humiture sensor, a heating device, a cooling device, a humidifying device and a dehumidifying device. By means of the device, the basic feature parameters of the charging pile during the discharge process are monitored, performance test of the charging pile before connecting the network is realized, and safety performance is guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of automobile charging equipment, and specifically relates to a charging pile performance testing device. Background technique [0002] In recent years, electric vehicles have developed rapidly. The construction of electric vehicle charging facilities, as the foundation and guarantee for the development of the electric vehicle industry, has also developed rapidly. As the core equipment of electric vehicle charging facilities, the performance of the charger is related to the safety of electric vehicle charging and discharging. At the same time, as the terminal power equipment, its performance will also affect the safe and stable operation of the power grid. With the increasing construction of car charging facilities, the network access testing of chargers has become increasingly important. [0003] In addition, the stable operation of charging pile equipment needs to ensure that its transformer works within a certa...

Problems solved by technology

[0003] In addition, the stable operation of the charging pile equipment needs to ensure that its transformer works within a certain temperature range, and the humidity and temperature in the charging pile cabinet can be controlled in a standard environment. The transformer is the main equipment of the charging pile, and it will generate heat during operation. Distributed into the environment, the other part is used to heat the transformer itself, if the temperature of the transformer is too high if the heat is not dissipated in time, it may reduce the service life of the transformer or even damage the transformer

The secondary equipment of the charging pile, that is, the equipment in the charging pile cabinet, is mostly weak current control equipment. If these electronic devices are exposed to high humidity in the wild for a long time, they are prone to corrosion or aging, electrical equipment and wiring. creepage phenomenon
