Problems solved by technology
[0005] Aiming at the deficiencies of the prior art, the present invention provides a DC charging pile with power quality monitoring function, which has the advantages of real-time monitoring of power supply quality and remote control, and solves the problem that the charging pile works independently. If the charging pile is working When the voltage is unstable, the voltage is insufficient, or the line is damaged, the staff cannot know it at the first time, and they cannot analyze and check the cause of the power supply failure on site, which delays the maintenance time of the charging pile and makes the charging pile unable to provide charging. Consequences, on the other hand, due to the modern power electronic technology used in charging piles, the charging pile itself cannot effectively monitor and record power quality pollution such as harmonics and load impacts on the grid

The invention relates to the technical field of direct-current charging piles and disclose discloses a DC charging pile with electric energy quality monitoring function, comprises a charging pile body, a fixing sleeve is fixedly connected to the right side of the charging pile body, a conduit is sleeved inside the fixing sleeve, a charging gun is fixedly installed at one end of the conduit away from the fixing sleeve, an operation panel is fixedly connected to the front side of the charging pile body, and an emergency stop button, an inductor and an indicator lamp are fixedly installed on thefront side of the operation panel. The DC charging pile with the electric energy quality monitoring function, the voltage of electrical energy, Current, frequency, power, harmonic, Flicker, unbalanceand demand parameters are monitored, analyzed, queried and set. The storage module at the top of the circuit board stores the monitored signals inside. The single-chip microcomputer control transmission module transmits the data signals in the single-chip microcomputer to the server remotely. The operator can compile and monitor the data transmitted to the server.
Description
technical field [0001] The invention relates to the technical field of DC charging piles, in particular to a DC charging pile with a power quality monitoring function. Background technique [0002] The function of the charging pile is similar to the refueling machine in the gas station. It can be fixed on the ground or the wall, and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential area parking lots or charging stations. It can be used according to different voltage levels For charging various types of electric vehicles, the input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging the electric vehicle. The charging pile generally provides two charging methods: conventional charging and fast charging. People can Use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile, and p...
