[0038] Hereinafter, exemplary embodiments of the present disclosure are described with reference to the accompanying drawings. The following description is provided to help fully understand the methods, devices and / or systems disclosed in detail. However, the following description is only exemplary and is not provided to limit the present disclosure.

[0039] In the following description of the embodiments of the present disclosure, when a detailed description of the known functions and configurations incorporated herein would make the subject matter of the present disclosure unclear, the detailed description of the known functions and configurations incorporated herein will be omitted. The terms used in this specification are defined in view of the functions used in the present disclosure and can be changed according to the intentions of customers, operators and users or conventional methods of use. Therefore, the definition of terms should be understood based on the entire description of this specification. The terms used in the following description are provided only to describe the exemplary embodiments of the present disclosure and are not intended to limit the inventive concept. As used herein, unless the context clearly indicates otherwise, the singular forms "one", "an" and "the" are intended to also include plural forms. It will be further understood that when the terms "including" or "having" are used in this specification, the presence of the features, integers, steps, operations, elements or a portion or combination thereof is specified, but the presence or addition of one or more other features, integers, steps, operations, elements or a portion or combination thereof is not excluded.

[0040] Figure 1 1 is a diagram illustrating a system including a power supply device mounted on an environmentally friendly vehicle according to an exemplary embodiment of the present disclosure. The system 100 may include a power supply device 110 mounted on the environmentally friendly vehicle 1 , an external device 120 , and a load 130 .

[0041] First, in an embodiment of the present disclosure, an environmentally friendly vehicle is an electric vehicle and may refer to a vehicle that includes an inlet for charging a high-voltage supply module installed therein using an external power source, such as an electric vehicle (EV), a plug-in hybrid electric vehicle (PHEV), etc.

[0042] In addition, the external device 120 is a device that requires a control voltage to operate and can be portable or fixed. If the external device 120 is portable, it can be shared and used by multiple users and can also be used at home, thereby bringing convenience to the user.

[0043] The external device 120 may be a direct current (DC) / alternating current (AC) converter that converts the DC voltage supplied by the power supply device 110 into an AC voltage and supplies it to the load 130, or the external device 120 may be a DC / DC converter that steps up or steps down the DC voltage and supplies it to the load 130. In this case, the load 130 may be a vehicle-to-everything (V2X) load.

[0044] For example, in the case where V2X is vehicle-to-load (V2L) or vehicle-to-home (V2H), the load 130 may be various electronic devices; in the case where V2X is vehicle-to-vehicle (V2V), the load 130 may be an environmentally friendly vehicle; and in the case where V2X is vehicle-to-grid (V2G), the load 130 may be a grid.

[0045] Alternatively, the external device 120 may be an AC / DC converter that converts AC voltage into DC voltage, and the power supply device 110 may be slowly charged by the converted DC voltage. In this case, the load 130 may be a power grid.

[0046] On the other hand, the power supply device 110 may include a socket including a plurality of terminals for fast charging and slow charging according to a charging connector standard.

[0047] Figure 2 1 is a diagram showing terminal (pin) configurations of CCS1 and CCS2 among charging connector standards. CCS1 may be referred to as DC combo type 1, and CCS2 may be referred to as DC combo type 2.

[0048] like Figure 2As shown, according to CCS1, two AC input terminals L1 and L2 / N, a proximity detection (PD) terminal, a control pilot (CP) terminal, a protective earth (PE) terminal, and DC input terminals DC+ and DC- can be set in the socket.

[0049] In addition, according to CCS2, three AC input terminals L1, L2 and L3, a neutral terminal, a PD terminal, a CP terminal, a PE terminal and DC input terminals DC+ and DC- can be set in the socket.

[0050] Among the above terminals, the PD terminal is a terminal for confirming that the connector is fastened to the receptacle and is referred to as a fastening confirmation terminal. In addition, the CP terminal is a terminal for communicating with an external device and is referred to as a communication terminal.

[0051] According to the charging connector standard, the on-board charger (OBC) may convert AC voltage input through the AC input terminal into DC voltage to slowly charge the high-voltage battery through the DC input terminal or quickly charge the high-voltage battery.

[0052] According to the above-mentioned charging connector standard, it can be seen that a terminal for supplying control power to an external device is not separately defined.

[0053] Therefore, in the embodiments of the present disclosure, among the terminals of the socket provided in the environmentally friendly vehicle, the AC input terminal for slow charging is used as the terminal for supplying the control voltage. In the embodiments of the present disclosure, CCS1 and CCS2, among the charging connector standards, are described, but the embodiments of the present disclosure can also be similarly applied to other charging connector standards (e.g., GB / T HPC, CHADEMO, etc.) that include multiple terminals for fast charging or slow charging.

[0054] on the other hand, Figure 3A is an internal block diagram of a power supply device of an OBC-equipped eco-friendly vehicle according to an exemplary embodiment of the present disclosure.

[0055] like Figure 3A As shown, the power supply device 110 may include a socket, a high-voltage supply module 111 , a low-voltage supply module 112 , an OBC 113 , a control module 114 , a first switch module 115 , and a second switch module 116 . Figure 3A The socket shown complies with the charging connector standard based on CCS1.

[0056] First, the high voltage supply module 111 is a high voltage battery that supplies high voltage to drive a motor, and the high voltage may be a DC voltage between 400V and 800V.

[0057] The low-voltage supply module 112 is a module that supplies low voltage to the electrical loads of the eco-friendly vehicle. The low-voltage supply module 112 can be an auxiliary battery or a low-voltage DC-DC converter (LDC) that receives high voltage from the high-voltage supply module 111 and converts it to a low voltage of 12V or 24V. Here, the low voltage can be a DC voltage between 12V and 48V.

[0058] In addition, if Figure 3A As shown, the DC input terminals DC+ and DC− of the socket can be connected to the high voltage supply module 111 through the second switch module 116 .

[0059] In addition, when any one of the L1 terminal and the L2 / N terminal constituting the AC input terminal of the socket is connected to the positive (+) terminal of the low voltage supply module 112 through the first switch module 115, the negative (-) terminal of the low voltage supply module 112 can be connected to the PE terminal. Figure 3A The L1 terminal is shown connected to the positive (+) terminal of the low voltage supply module through the first switch module 115 .

[0060] Also, the CP terminal and the PD terminal may be connected to the control module 114 .

[0061] On the other hand, although not shown in the figure, in the case of CCS1, when either the L1 terminal or the L2 / N terminal constituting the AC input terminal is connected to the positive (+) terminal of the low-voltage supply module 112, the negative (-) terminal of the low-voltage supply module 112 can be connected to the other of the L1 terminal and the L2 / N terminal. In this case, the first switch module 115 can be provided between either the L1 terminal or the L2 / N terminal and the positive (+) terminal of the low-voltage supply module 112, and between the other of the L1 terminal and the L2 / N terminal and the negative (-) terminal of the low-voltage supply module 112.

[0062] In addition, although not separately shown in the figure, in the case of CCS2, when the AC input terminal is one of the L1 terminal, L2 terminal, and L3 terminal, the negative (-) terminal of the low-voltage supply module 112 can be connected to the PE terminal. Similarly, of course, the DC input terminal can be a DC+ terminal and a DC- terminal, the fastening confirmation terminal can be a PD terminal, and the communication terminal can be a CP terminal.

[0063] The first switch module 115 and the second switch module 116 may be relays or semiconductor switch elements. The semiconductor switch elements may include field effect transistors (FETs), metal oxide semiconductor FETs (MOSFETs), insulated gate bipolar transistors (IGBTs), thyristors, gate turn-off (GTO) thyristors, triodes (TRIACs), silicon controlled rectifiers (SCRs), etc.

[0064] Of course, when slow charging or fast charging is performed by the slow charging facility or the fast charging facility, the first switch module 115 may be in the off state.

[0065] On the other hand, when the connector of the external device 120 is fastened to the socket, the control module 114 may turn on the first switch module 115 to supply a control voltage to the external device 120. In addition, the control module 114 may turn on the second switch module 116 to supply the high voltage of the high voltage supply module 111 to the external device 120 or slowly charge the high voltage supply module 111 with the voltage supplied from the external device.

[0066] The control module 114 may include a processor (e.g., a computer, microprocessor, CPU, ASIC, logic circuit, etc.) and a memory that stores software instructions that provide various functions when the processor is executed. Here, the processor and memory may be implemented as separate semiconductor circuits. Alternatively, the processor and memory may be implemented as a single integrated semiconductor circuit. One or more processors may be provided.

[0067] In the following, reference is made to Figures 1 to 3A A process of supplying voltage from the power supply device 110 to the external device 120 is described.

[0068] according to Figures 1 to 3A When the connector of the external device 120 is fastened to the socket, the control module 114 may turn on the first switch module 115 to supply the control voltage to the external device 120 .

[0069] Specifically, when it is confirmed through the fastening confirmation terminal, ie, the PD terminal, that the connector of the external device 120 is fastened to the socket, the control module 114 may turn on the first switch module 115 .

[0070] Thereafter, when it is confirmed that the communication with the external device 120 is normal through the communication terminal, ie, the CP terminal, the control module 114 may be configured to lock the socket and the connector of the external device 120 by controlling a locking device (not shown).

[0071] Thereafter, when a request for high voltage is received from the external device 120 through the communication terminal, ie, the CP terminal, the control module 114 may turn on the second switching module 116 to supply the high voltage to the external device 120 .

[0072] Afterwards, when receiving a request to terminate the control voltage through the communication terminal, ie, the CP terminal, the control module 114 may sequentially turn off the second switch module 116 and the first switch module 115 , and then control the locking device to unlock the connector between the socket and the external device 120 .

[0073] on the other hand, Figure 3Bis an internal block diagram of a power supply device of an environmentally friendly vehicle not equipped with an OBC according to an exemplary embodiment of the present disclosure.

[0074] like Figure 3B As shown, when any one of the L1 terminal and the L2 / N terminal constituting the AC input terminal of the socket is connected to the positive (+) terminal of the low voltage supply module through the first switch module 115, the negative (-) terminal of the low voltage supply module can be connected to the PE terminal.

[0075] exist Figure 3B In this case, the control power and high voltage can be Figure 3A The same manner is applied to the external device 120, and thus a detailed description thereof is omitted here.

[0076] on the other hand, Figure 4 is a diagram illustrating an operation of a first switching module when a control voltage is supplied to an external device according to an exemplary embodiment of the present disclosure.

[0077] like Figures 1 to 4 As shown, when the connector of the external device 120 is fastened to the socket of the environmentally friendly vehicle and the first switch module 115 is turned on, the power supply device 110 may supply the control voltage to the external device 120 .

[0078] on the other hand, Figure 5A 1 is a diagram showing that an eco-friendly vehicle equipped with an OBC supplies high voltage to an external device or an external device charges the high voltage supply module. The external device 120 may be a device that requires a controlled voltage to operate, and for this purpose, the first switch module 115 may be turned on.

[0079] like Figure 5A As shown, the external device 120 may provide a high voltage (see D1) to the load 130. To this end, the second switch module 116 may be turned on.

[0080] In this case, external device 120 may be a DC / AC converter that converts the high voltage from high-voltage supply module 111 into an AC voltage and supplies the AC voltage to load 130. Alternatively, external device 120 may be a DC / DC converter that steps up or steps down the high voltage from high-voltage supply module 111 and supplies it to load 130. Load 130 may be a V2X load. For example, if V2X is V2L or V2H, load 130 may be various electronic devices; if V2X is V2V, load 130 may be an environmentally friendly vehicle; and if V2X is V2G, load 130 may be a power grid.

[0081] Alternatively, if the OBC 113 has a small capacity (e.g., 7 kW) or is damaged, an external device 120 with a large capacity (e.g., 22 kW) can be used to slowly charge the high-voltage supply module 111 at high power (see D2). In this case, the external device 120 can be an AC / DC converter that converts the AC voltage provided by the load 130 into a DC voltage, and the converted DC voltage can be directly used to slowly charge the high-voltage supply module 111 through the DC input terminal.

[0082] on the other hand, Figure 5B 1 is a diagram illustrating that an eco-friendly vehicle not equipped with an OBC supplies high voltage to an external device or an external device charges a high voltage supply module.

[0083] like Figure 5B As shown, in the case that the environmentally friendly vehicle is not equipped with OBC, Figure 5A In the same manner, the external device 120 can provide high voltage to the load 130 (see D1 ), or use the external device 120 with a large capacity (eg, 22 kW) to slowly charge the high voltage supply module 111 with high power (see D2 ).

[0084] As described above, according to exemplary embodiments of the present disclosure, control power can be supplied to an external device by using an AC input terminal for slow charging among terminals of a socket provided in an eco-friendly vehicle as a terminal for supplying a control voltage.

[0085] According to an exemplary embodiment of the present disclosure, regardless of whether the OBC is set or damaged, a high-voltage battery mounted on an environmentally friendly vehicle can be charged with high power through an external device, or high voltage from the high-voltage battery can be supplied to a load through an external device.

[0086] on the other hand, Figure 6 is a flowchart illustrating a power supply method of an environmentally friendly vehicle according to an exemplary embodiment of the present disclosure.

[0087] In the following, reference is made to Figures 1 to 6 , describes the power supply method of the environmentally friendly vehicle according to the exemplary embodiment of the present disclosure. However, for simplicity, the Figure 1 Same description.

[0088] Reference Figures 1 to 6 The power supply method (S600) of the environmentally friendly vehicle according to the exemplary embodiment of the present disclosure may start with an operation (S601) of determining whether the connector of the external device 120 is fastened to the socket of the power supply device 110. As described above, whether the connector is fastened may be determined through the fastening confirmation terminal, i.e., the PD terminal.

[0089] If, as a result of the determination in operation S601 , it is determined that the connector of the external device 120 is fastened to the socket, the power supply device 110 may turn on the first switching module 115 to supply a control voltage to the external device 120 ( S602 ).

[0090] Thereafter, the power supply device 110 may determine whether communication with the external device 120 is normal through the communication terminal, ie, the CP terminal ( S603 ).

[0091] If, as a result of the determination in operation S603 , it is determined that the communication with the external device 120 is normal, the power supply device 110 may operate a locking device (not shown) to lock the socket and the connector of the external device 120 ( S604 ).

[0092] Thereafter, the power supply device 110 may determine whether a request for a high voltage is received from the external device 120 through the communication terminal, ie, the CP terminal ( S605 ).

[0093] If a request for high voltage is received as a result of the determination in operation S605 , the power supply device 110 may turn on the second switching module 116 to supply high voltage to the external device 120 ( S606 ).

[0094] Thereafter, the power supply device 110 may determine whether a request for terminating the control voltage is received through the communication terminal, ie, the CP terminal ( S607 ).

[0095] If a request to terminate the control voltage is received as a result of the determination in operation S607 , the power supply device 110 may sequentially turn off the second switching module 116 and the first switching module 115 and then release the operation of the locking device ( S608 to S610 ).

[0096] On the other hand, if the OBC 113 has a small capacity (e.g., 7 kW) or is damaged, or if the OBC 113 does not exist, the high voltage supply module 111 can be slowly charged with high power using an external device 120 having a large capacity (e.g., 22 kW) as described above.

[0097] As described above, according to exemplary embodiments of the present disclosure, control power can be supplied to an external device by using an AC input terminal for slow charging among terminals of a socket provided in an eco-friendly vehicle as a terminal for supplying a control voltage.

[0098] According to an exemplary embodiment of the present disclosure, regardless of whether the OBC is set or damaged, a high-voltage battery mounted on an environmentally friendly vehicle can be charged with high power through an external device, or the high voltage of the high-voltage battery can be supplied to a load through an external device.
