[0034] Figure 1a A structural schematic diagram of a charging pile detection device provided for the first embodiment of the present application, the present embodiment can be used for detecting the failure of the charging pile. The embodiment of the present application can be realized by the following technical scheme.

[0035] As Figure 1a shown, the charging pile detection device of the embodiment of the present application comprises a detection circuit 101 and a detection probe 102; the detection circuit 101 comprises a plurality of electronic components and integrated circuits between the electronic components; wherein the plurality of electronic components comprises at least one capacitor, resistor, inductor, transistor and operational amplifier.

[0036] In the embodiment, the charging pile can be installed in underground parking garage, public parking lot, residential parking lot, enterprise special parking lot and various outdoor and indoor places, and is used for charging the electric vehicle equipped with lead-acid battery and lithium ion battery.

[0038] The detection circuit 101 is used for detecting the running condition of the target circuit according to the target current, and feeding back the detection result.

[0039] In a specific embodiment, the detection probe 102 can be made of a predetermined metal, such as copper, aluminum and the like. Specifically, the detection probe 102 can be used to contact the target circuit to obtain the target current in the target circuit.

[0040] Integrated circuits between each electronic component in the detection circuit 101, for interconnecting each electronic component and wiring together, and integrated on a semiconductor wafer or dielectric substrate, to achieve the functions of the detection circuit together.

[0041] In one specific embodiment, Figure 1b A structure diagram of a detection circuit in a charging pile detection device provided by the embodiment one of the present application is shown.

[0043] In which, one end of the capacitor C1 can be connected with the resistor R1, and the other end can be connected with the ground terminal (GND1).

The other end of the resistor R2 can be connected with the base of the transistor Q1, the other end of the resistor R3 can be connected with one end of the capacitor C4, and the other end of the capacitor C4 can be connected with the detection circuit output interface 14.

The current at each circuit component of the detection circuit can produce different current conditions according to the different size of the target current, so as to reflect the different running conditions of the target circuit.

[0046] For example, when the current of the target circuit passes through the detection circuit 101, if it is detected that the current at the resistor C1 is insufficient, it indicates that the target circuit or the components in the target circuit may be damaged.

[0051] In the embodiment, after the detection probe 102 obtains the target current in the target circuit, the target current can be guided into the detection circuit 101 through the second peripheral interface 204 and the first peripheral interface 203.

[0052] Further, the second peripheral interface 204 of the charging pile detection device of the embodiment of the present application is connected with the detection probe 102 through the spring wire 205 to obtain the target current corresponding to different positions in the target circuit.

The advantage of such arrangement is that the spring wire can be flexibly stretched and contracted, and the detection probe 102 can be flexibly and accurately contacted with different positions of the target circuit through the spring wire connection mode, so that the currents corresponding to different positions are obtained.

[0054] Further, the charging pile detection device provided by the embodiment of the application further comprises a display screen 206 connected with the detection circuit 101 through the first peripheral interface 203 (not shown in the figure).

[0055] In the embodiment, when the target current passes through the detection circuit 101, the display screen 206 can clearly display the detection result fed back by the detection circuit 101, so that the detection personnel can better obtain the operation condition of the target circuit and the operation condition of the electronic components in the target circuit.

[0059] As shown in Figure 3 The charging pile detection method provided by the embodiment of the application specifically comprises the following steps:

[0060] S301, a detection probe is used to sequentially contact a plurality of groups of target circuits of an inbuilt circuit board of a charging pile and obtain a target current corresponding to each group of target circuits.

[0061] Specifically, relevant detection personnel can make the detection probe flexibly contact the inbuilt circuit board of the charging pile by stretching the spring wire, so as to contact a plurality of groups of target circuits of the circuit board and obtain a target current corresponding to each group of target circuits.

[0062] S302, determining the running condition of each group of target circuits according to the target current corresponding to each group of target circuits through the detection circuit.

[0063] Specifically, the target circuit will feedback different current conditions under normal and abnormal conditions. The detection circuit can determine different target circuit running conditions according to different target current conditions.

[0064] For example, the current value of the normal circuit can be kept within a fixed current value range. The current condition of the abnormal circuit can be no current in the circuit, the current value greater than the preset current value, or the current value less than the preset current value, etc.

[0065] S303, if the target circuit is detected to run abnormally, the detection probe is used to sequentially contact each electronic component in the target circuit, and the target current corresponding to each electronic component is obtained.

[0066] Specifically, when the detection circuit determines that the target circuit is abnormal, the detection probe can be used to contact each electronic component of the abnormal target circuit by stretching the spring wire, and the target current of each electronic component of the abnormal target circuit is obtained.

[0067] S304, determining the abnormal device in the target circuit according to the target current corresponding to each electronic component through the detection circuit.

[0068] Specifically, the electronic component will feedback different current conditions under normal and abnormal conditions. The detection circuit can determine the abnormal component in the abnormal circuit according to the target current corresponding to each electronic component.

[0069] For example, the current value of the normal electronic component can be kept within a fixed current value range. The current condition of the abnormal electronic component can be no current in the electronic component, the current value greater than the preset current value, or the current value less than the preset current value, etc.

[0070] The technical scheme of the embodiment of the application sequentially contacts the multiple groups of target circuits of the built-in circuit board in the charging pile through the detection probe, and obtains the target current corresponding to each group of target circuits; the running condition of each group of target circuits is determined according to the target current corresponding to each group of target circuits through the detection circuit;

[0071] If the target circuit is detected to run abnormally, the detection probe is used to sequentially contact each electronic component in the target circuit, and the target current corresponding to each electronic component is obtained; the abnormal device in the target circuit is determined according to the target current corresponding to each electronic component through the detection circuit. The technical means can quickly detect the damage condition of the circuit and the circuit components of the charging pile, and provide convenience for the detection and maintenance of the charging pile.

[0072] Embodiment Four

[0073] Figure 4 A flowchart of another charging pile detection method provided by Embodiment Four of the present application is shown. The technical solution of the present embodiment is a further refinement based on the technical solution of Embodiment Three described above. The technical solution of the present embodiment can be combined with each of the optional implementation manners of Embodiment Three described above.

[0074] As shown in Figure 4 , a flowchart of another charging pile detection method provided by the present embodiment is shown, which specifically includes the following steps:

[0075] S401, by means of the detection probe, sequentially contact multiple groups of target circuits of the built-in circuit board in the charging pile, and obtain the target current corresponding to each group of target circuits.

[0076] S402, by means of the detection circuit, obtain the quantity value of the target current in the target circuit, and determine the quantization level of the target current according to the quantity value.

[0077] In the present embodiment, a plurality of current quantization levels can be preset. After the detection circuit obtains the target current in the target circuit, the quantity value of the target current can be referred to to determine the quantization level of the target current according to the value range of each current quantization level.

[0078] For example, each current quantization level can be a preset quantity value range or a quantity value. For example, the first current quantization level can be a sufficient current quantity value range. The second current quantization level can be less than the sufficient current quantity value range and maintained in another preset quantity value range. The third current quantization level can be greater than the sufficient current quantity value range. The fourth current quantization level can be insufficient current, i.e., less than the current quantity value range of the second current quantization level.

[0079] S403, according to the quantization level of the target current, determine the reference node in the detection circuit that matches the quantization level, and according to the current condition of the reference node, determine the running condition of the target circuit.

[0080] In the present embodiment, optionally, before obtaining the quantity value of the target current in the target circuit, a mapping relationship between different current quantization levels and corresponding reference nodes can be established in advance. After the quantization level of the target current is determined, the reference node that matches the quantization level can be determined according to the mapping relationship. The reference node can be a detection point in the detection circuit, such as at least one electronic component in the detection circuit, or a ground terminal, etc.

[0081] In this step, optionally, after determining the reference nodes, the operating status of the target circuit can be determined based on the current status of each reference node. The operating status can include normal operation and abnormal operation.

[0082] For example, with Figure 1b Taking the detection circuit as an example, assuming the target current quantization level is the first current quantization level, the corresponding reference nodes can be resistor R1, capacitor C1, and capacitor C2 in the detection circuit. The target current can pass through R1 into C1 and C2. Assuming the target current quantization level is the second current quantization level, the corresponding reference node can be capacitor C1 in the detection circuit. If the target current can pass through C1, the target circuit is normal; if it cannot pass through C1, the target circuit is abnormal. Assuming the target current quantization level is the third current quantization level, the corresponding reference nodes can be capacitor C2, capacitor C3, inductor L, and ground GND2 in the detection circuit. If the target current passes through C2, C3, and L and is consumed by GND2, the target circuit is normal; if no target current is consumed by GND2, it is abnormal. Assuming the target current quantization level is the fourth current quantization level, the corresponding reference nodes can be resistor R2, resistor R3, and ground GND3 in the detection circuit. If the target current passes through R2 and R3 and directly enters GND3 for dissipation, the current is too low, and the power supply circuit is abnormal.

[0083] S404. Transmit the operating status of each target circuit to the display screen to display the operating status of each target circuit.

[0084] In this embodiment, the detection circuit transmits the current or voltage signals corresponding to the operating status of each group of target circuits detected in S403 to the display screen. The display screen can display the corresponding text display results (i.e., "target circuit is operating normally" or "target circuit is operating abnormally") based on the pre-stored mapping relationship between different current or voltage signals and text display results.

[0085] For example, when the target current of a certain target circuit is at the second quantization level, if the detection circuit detects that the target current cannot pass through the reference node C1, the display screen will show the word "abnormal" for that target circuit.

[0086] S405. If an abnormality is detected in the target circuit, the detection probe will sequentially contact each electronic component in the target circuit and obtain the target current corresponding to each electronic component.

[0087] S406. By using the detection circuit, the abnormal device in the target circuit is determined according to the target current corresponding to each electronic component.

[0088] S407, transmit the identification information of the abnormal device to the display screen to display the identification information of the abnormal device on the display screen.

[0089] In the embodiment, after the detection circuit detects the abnormal device, the corresponding current signal or voltage signal can be fed back to the display screen according to the mapping relationship between the pre-stored current signal or voltage signal and the identification information of the abnormal device. After the display screen receives the current signal or voltage signal, the identification information of the corresponding abnormal device can be displayed according to the mapping relationship.

[0090] The identification information can include the name, model number, code, etc. of the abnormal device.

[0091] Further, in an optional embodiment of the present application, after determining the operation of each group of target circuits, the method further comprises:

[0092] If the operation of each group of target circuits is detected to be abnormal, the power supply circuit replacement information is transmitted to the display screen, so that the user replaces the power supply circuit of the built-in circuit board in the charging pile according to the power supply circuit replacement information.

[0093] Specifically, taking the detection circuit of Figure 1b For example, when the detection circuit detects that the target current of each group of target circuits is the fourth current amount level, and the corresponding target current is directly converted into the reference node GND3 through the reference nodes R2 and R3 for loss, it indicates that each group of target circuits shows the power supply circuit abnormality. The detection circuit feeds back the detection result of this condition to the display screen, and the display screen displays the power supply circuit replacement message. In this case, the relevant detection personnel can replace the power supply circuit of the built-in circuit board in the charging pile according to the display result of the display screen.

[0094] In a specific embodiment, the detection device of the charging pile can be deployed in the charging pile, so that the user can detect the abnormal condition of the charging pile at any time.

[0095] The technical scheme of the embodiment of the present application comprises the following steps: a detection probe is used to sequentially contact multiple groups of target circuits of a built-in circuit board in a charging pile and obtain target currents corresponding to each group of target circuits; a detection circuit is used to obtain a quantity value of the target currents in the target circuits and determine a quantization level of the target currents according to the quantity value; a reference node in the detection circuit that matches the quantization level is determined according to the quantization level of the target currents, and the operation condition of the target circuit is determined according to the current condition of the reference node; the operation condition of each group of target circuits is transmitted to a display screen to display the operation condition of each group of target circuits through the display screen; if an abnormal operation of the target circuit is detected, the detection probe is used to sequentially contact each electronic component in the target circuit and obtain target currents corresponding to each electronic component; the detection circuit is used to determine an abnormal component in the target circuit according to the target currents corresponding to each electronic component; and the identification information of the abnormal component is transmitted to the display screen to display the identification information of the abnormal component through the display screen. The technical scheme can timely and accurately detect the operation condition of the charging pile circuit and the electronic component, the detection of the built-in circuit of the charging pile has a sequence, the detection efficiency and accuracy are improved, and the detection and maintenance of the charging pile are facilitated.
