Embodiment 2

[0054] In addition to providing a mobile error standard structure for charging pile error detection as described in Embodiment 1, the embodiment of the present invention also provides a charging pile error detection method based on a mobile error standard, such as Figure 5 As shown, when the error calculation server calculates the overall error of the charging piles in a designated charging station and the charging pile power consumption of each charging pile, the detection method and system include the following steps:

[0055] In step 201, the error calculation server retrieves the stored one or more mobile error standards used to detect the charging pile in the charging station, and according to the sub The electric energy passing through the electric meter is the same as the electric energy passing through the mobile error standard device, and the overall error value of the sub-electric meters of one or more charging guns is calculated.

[0056] In step 202, the error cal...

Embodiment 3

[0067] On the basis of the content of Embodiment 2, this implementation describes how to calculate the power consumption of the charging pile through the environment involving specific implementation parameters. In this embodiment, it is assumed that the incoming line of the substation is three-phase and four-circuit (single-phase is 380V), and after transformation, there are two 450V DC outputs. In this embodiment, the error standard device and the equipment used to complete the electric energy metering in the charging pile are all called electric energy metering devices, and the schematic diagram of the substation is as follows Figure 6 Shown:

[0068] W 1 (1+X 1 )*(1+X S ) = W 2(1+X 2 )+W 3 (1+X 3 )

[0069] Among them, W i =1,2,3 are the electric energy readings of the electric energy metering device on the high and low voltage side of the transformer; X i = 1, 2, 3 are W i =The error of the electric energy metering device where 1, 2, and 3 are located; X s It...

Abstract

The invention relates to the technical field of charging piles, and provides a mobile error standard for charging pile error detection, and a detection method and a detection system thereof. An electric energy metering chip, a wireless transceiver module, a display screen, a storage module and a processor in the mobile error standard are fixed on a central control table of the mobile error standard; the central control table is located between a power supply interface and a vehicle interface; the central control table is also provided with a mechanical lock, and the lock head of the mechanical lock is located in the vehicle interface direction for being locked with a mechanical lock groove in a vehicle socket when the vehicle interface is inserted in the vehicle socket; and the power supply interface is also provided with the mechanical lock groove. through arranging the mobile error standard in the existing charging pile, an energy conservation system of the error standard is combined, and electric energy related data reported by each sub electric meter and a three-phase electric meter and electric energy related data detected by the mobile error standard itself are used for completing building and solution of equations to obtain electric energy loss of the charging pile.

Description

【Technical field】 [0001] The invention relates to the technical field of charging piles, in particular to a mobile error standard for charging pile error detection and a detection method and system thereof. 【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 wall, and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential area parking lots or charging stations. Charge all models of electric vehicles. The input end of the charging pile is directly connected to the AC grid, and the output end is equipped with a charging plug for charging the electric vehicle. Charging piles generally provide 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 to perform corresponding charging method...
