Background
Along with the popularization of new energy automobiles, more and more problems such as endurance mileage, safety, electromagnetic compatibility and the like are always plagued by research and development engineers, and a perfect solving measure is needed to truly promote the development of the new energy automobiles. Particularly in the field of electromagnetic compatibility, the electromagnetic emission and sensitivity of a single device are relatively easy to solve, but the electromagnetic compatibility problem of the quality inspection of a subsystem in an electric control system is difficult to process, so that unreliability caused by the electromagnetic interference problem between systems can be caused, the broadcasting communication quality is influenced when the system is light, and the safety accident is directly caused when the system is heavy. At present, no good solving measures are found at home and abroad, because the problem of electromagnetic compatibility is too complex, the repeatability is low, and the problem is difficult to solve in an all-round way. Therefore, it is necessary to perform omnibearing safety and reliability detection before new energy automobiles are formally marketed, and electromagnetic compatibility detection is one of the important factors. The three-electric system of the new energy automobile comprises a motor, a battery and an electric control, wherein the electromagnetic compatibility detection of the battery in a charging mode is particularly important, and the actual electromagnetic interference state in the charging mode is embodied. In order to realize the electromagnetic compatibility test in the charging mode, the international standard ECE R10 and the national standard GB/T34660 are described in detail for the charging mode, but the description of how the charging pile enters the anechoic chamber (test environment) is not provided, so that the technical scheme of the interface for the charging pile entering the anechoic chamber needs to be considered in advance, the whole shielding performance and other field performance indexes of the anechoic chamber cannot be influenced, and meanwhile, the safety of electricity utilization is ensured.
The wire harness output by the charging pile is many, and has a power wire and a signal wire, and similar situations such as a conventional various power sources such as a 50Hz power grid enter a darkroom through a power filter, a telephone wire enters the darkroom through the filter, and the output wire harness of the charging pile is more complicated.
Whether it is an ac charging stake or a dc charging stake, the cable bundle of its output has not only power cord but also signal line including the interactive communication with vehicle or battery pack BMS system and the monitoring line of safety guarantee charging such as control by temperature change line, on-off state monitoring system etc.. The traditional power supply or analog signal source enters the shielding room through a special filter interface, and the traditional filter has a good transmission function on analog signals, but has a great difference on the power supply and the signals of the charging pile, for example, the power of the direct current charging pile is usually hundreds of kilowatts, the output voltage is up to more than 1000V, and the charging current is up to more than 250A. The interactive signals are also very special, and basically are high-speed digital signals, such as PWM (pulse-width modulation) waves and CAN (controller area network) bus signals, and the problem of an interface passing through a shielding chamber cannot be solved by a conventional passive filter, so that the attenuation of the high-speed digital signals occurs when the high-speed digital signals pass through a shielding layer, normal charging and communication between a charging pile and a new energy automobile are influenced, and the problem is solved by adopting a more special interface technical scheme.

Interface key technical index:
(1) Shielding effectiveness: 10KHz-40GHz. As shown in table 1.
Table 1 interface key technical index
(2) Filter insertion loss: frequency range: the insertion loss IL is more than or equal to 100dB at 14kHz-40 GHz.
As shown in fig. 3, from a to B, through the shield, in order to ensure that the shielding effectiveness index of the shield is not affected, and that the transmitted signal is not damaged by the filter, the technical solution of the present application is provided. The process from A to B is divided into two parts, wherein the first part is the transmission of a power line, and both an alternating current power supply and a direct current power supply can be realized through corresponding power supply filters; for the signal lines, the signal types of the alternating current charging pile and the direct current charging pile are completely different, and different processing modes are adopted to realize the alternating current charging pile and the direct current charging pile.
The specific solution is described as follows:
(1) For the interface technical scheme of AC charging pile output, the solving steps are as follows:
the AC output of the AC charging pile is usually 380V, 220V and 50Hz, and the current specifications are 16A,32A and 63A;
the interactive communication signal of the alternating-current charging pile is a PWM wave, the alternating-current charging pile is a square wave, the frequency spectrum is rich, and a conventional filter can distort the waveform of a noise signal, so that the charging pile and a new energy automobile cannot normally communicate. The problem can be well solved by adopting the built-in optical transceiver and adding a logic communication module scheme. This is the most efficient way for PWM, which is a special signal. The shell is a metal shell of the filter, and the installation interface connected with the shielding body is similar to a conventional shielding interface, so that the problem of PWM (pulse width modulation) lossless passing is solved, and the problem of shielding effectiveness of the shielding body is also ensured.
The structure diagram of the interface of the alternating current charging pile is shown in fig. 1, and the connection method comprises the following steps:
step 1: firstly, removing gun heads of the alternating-current charging piles to expose all wire harnesses;
step 2: connecting a power wire in the gun head wire harness to an input terminal of a power wire filter;
step 3: connecting a connection confirmation line (CC) in the gun head wire harness to an input terminal of a corresponding filter;

step 5: leading out a power line from the inner side of the shielding body, and connecting the power line to the corresponding ground interface board position in the darkroom;
step 6: leading out the CC line from the inner side of the shielding body, and connecting the CC line to the corresponding ground interface board position in the darkroom;
step 7: and leading out the CP wire from the inner side of the shielding body, and connecting the CP wire to the corresponding ground interface board position in the darkroom.
The structure of the gun head of the alternating current charging gun is shown in fig. 4, and parameters of the gun head of the alternating current charging gun are shown in table 2.
Table 2 contact electrical parameter values and function definitions
(2) For the interface timely scheme of the direct current charging pile output, the solving steps are as follows:
the voltage output by the direct current charging pile is up to 1000V, the current is 250A, a filter and a cable which are high in withstand voltage and easy to dissipate heat are needed, and a shielding cable and a connector are needed in consideration of the background noise of an anechoic chamber;
the signals output by the direct current charging pile comprise CAN H and CAN L, which belong to high-speed transmission digital signals, and the conventional signal filter still CAN cause attenuation and distortion of the signals. The optimal technical scheme is that an optical transceiver is adopted, so that the lossless transmission of high-speed digital signals can be well avoided. The optical transceiver is usually 2 modules, one is located outside the shielding room and is used for converting electricity into light, and the other is located inside the shielding room and is responsible for converting the light into electricity. To ensure shielding against background noise inside the chamber, the optical transceiver in the chamber is typically shielded. The two modules are connected by an all-fiber line and are transmitted into the shielding chamber through special fiber waveguides on the wall surface of the shielding chamber.
The structure diagram of the interface of the direct current charging pile is shown in fig. 2, and the connection method comprises the following steps:
step 1: firstly, removing gun heads of the direct-current charging piles to expose all wire harnesses;
step 2: connecting a power wire in the gun head wire harness to an input terminal of a power wire filter;
step 3: connecting a connection confirmation line (CC) in the gun head wire harness to an input terminal of a corresponding filter;
step 4: connecting charging communication wires (CAN_H, CAN_L) in the gun head wire harness to an input terminal of the optical transceiver;
step 5: leading out a power line from the inner side of the shielding body, and connecting the power line to the corresponding ground interface board position in the darkroom;
step 6: leading out the CC line from the inner side of the shielding body, and connecting the CC line to the corresponding ground interface board position in the darkroom;
step 7: and leading out the CAN charging communication line from the inner side of the shielding body, and connecting the CAN charging communication line to the corresponding ground interface board position in the darkroom.
The structure of the gun head of the direct current charging gun is shown in fig. 5, and parameters of the gun head of the direct current charging gun are shown in table 3.
TABLE 3 contact Electrical parameter values and function definition
(3) For the treatment scheme of the temperature control line and the safety monitoring line of the alternating current and direct current charging piles:
the temperature control line of the charging pile only monitors the heating condition of the charging gun head in the charging process, and is not directly connected with a vehicle or a battery pack, so that the temperature control line is not required to be connected into the shielding chamber, and the temperature of the power line can be monitored at the charging pile side. Another safety monitoring of the charging stake is through detecting the insulation resistance and leakage current magnitude of the vehicle or battery pack during charging. However, if the line of the charging pile entering the darkroom is connected with the LISN and the power filter, the charging pile and the power filter cannot be charged normally, and the leakage current of the LISN and the power filter is too large to exceed the limit value of the charging pile and the vehicle. The other point is that the insulation resistance detected by the charging pile is not large enough, and a safety fault alarm can also occur, and the reason is that the discharging resistance of the filter is only 1MOhm, so that the discharging resistance of the filter cannot be too large, otherwise, the discharging time is influenced. For these problems, it is necessary to shield the insulation resistance and the leak detection function on the charging pile side, and the entire function does not affect the test of EMC.
The application further provides a charging pile, which comprises the charging pile intelligent interface device suitable for EMC test.
The interface scheme for the AC/DC charging pile well solves the defects of the traditional interface scheme, solves the power transmission of high voltage and high current, the lossless transmission of high-speed digital signals and the shielding performance of a shielding room. For the new energy automobile industry advocated in the present country, the application can assist the benign development of the new energy automobile in the aspect of EMC performance.
