Description

Technical Field

[0001] The utility model belongs to the field of on-vehicle battery charging sockets, and particularly relates to a multifunctional dual-standard on-vehicle battery charging socket. Background Art

[0002] An on-vehicle battery charging socket, usually called an on-vehicle charging interface, is an interface used to charge the batteries of electric vehicles, electric bicycles or other electric vehicles. It establishes an electrical connection between the vehicle and the charging infrastructure for charging.

[0003] With the development of new energy vehicles, electric trucks have gradually developed in some places. Electric trucks operating alone in a single area do not have the problem of specification differences. However, the charging equipment in the inland areas of China follows the national standard, while in the Hong Kong Special Administrative Region of China, the European standard is implemented. And some vehicles need to travel between the Hong Kong region and the Shenzhen region. Thus, no matter which charging standard is set alone, it will bring inconvenience to truck drivers and operations.

[0004] At the same time, for trucks with a battery capacity of 282 kwh, the existing charging sockets have a slow charging speed when using a single charging device; when using a single standard charging socket, other charging sockets are in a high-voltage live state, and accidental contact is likely to cause injury or death.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment

[0036] It is given by Figures 1-6 A multifunctional dual-standard vehicle-mounted battery charging socket includes a battery pack, two sets of national standard charging sockets and two sets of European standard charging sockets;

[0037] A distribution box is arranged between the charging socket and the battery pack;

[0038] Several groups of power relays and a group of two-way PNP optoelectronic signal modules are arranged in the distribution box;

[0039] In the preferred embodiment of the arranged power relay, as shown in Embodiment Figure 3 In the figure, there are eight groups of power relays, which are power relay J1 to power relay J8 respectively;

[0040] A wire-passing connector female socket is also configured to be connected to the wire-passing connector male head of the battery pack for transmitting signals;

[0041] The wire-passing connector female socket includes a wire-passing connector female socket No. 2 pin, a wire-passing connector female socket No. 3 pin, a wire-passing connector female socket No. 6 pin and a wire-passing connector female socket No. 7 pin;

[0042] It also includes:

[0043] Two groups of fuse boxes, which are fuse box F1 and fuse box F2 respectively;

[0044] Among them, the No. 1 pin of the wire-passing connector female socket is the signal ground of the PE charging gun, which passes through the fuse box F2 and is connected to the S / S of the two-way PNP optoelectronic signal module.

[0045] In this embodiment, the charging socket of the present application can simultaneously use two charging plugs of the same type to charge the battery pack. In actual assembly and use, the charging time of the vehicle-mounted battery can be reduced by half.

[0046] Furthermore, in actual use, the charging socket of the present application can use a national standard charging socket to charge the battery pack in mainland China, or use a European standard charging socket to charge in Hong Kong, China.

[0047] Even further, the charging socket of the present application has an anti-electric shock mode. When charging with one type of charging socket, the other charging socket is in a power-off state; when one type of charging socket is already connected, the other type of charging socket cannot be charged even if it is connected, protecting the battery from being damaged by different types of charging specifications.

[0048] In a preferred embodiment, as shown in the embodiment Figure 3 Z1 to Z8 are quick-connect terminals configured inside the socket.

[0049] It should be noted that in actual scenario usage, considering the differences between the two charging sockets, simultaneously using a European standard charging socket and a national standard charging socket may cause damage to the battery pack. Therefore, in a preferred embodiment, as shown in the embodiment of the present application Figure 2 When connecting one standard charging socket, the other standard charging socket will not be charged even if it is connected. The specific principle is as follows: When the charging handshake signal is fed back to the two-channel PNP optoelectronic signal module, since the two-channel PNP optoelectronic signal module has already received the handshake signal of the other charging type, the two-channel PNP optoelectronic signal module will not activate the signal current (10 mA) connected to the power relay. Therefore, the power relay remains in the off state.

[0050] Even further, the principle of the anti-touch mode in the present application is as follows: As shown in the specific embodiment Figures 1-2As shown in the figure, taking the connection of two European standard charging sockets as an example, when the 1# European standard charging socket and the 2# European standard charging socket are connected to an external charging pile, the European standard charging handshake signal of the 3rd pin of the through-board connector female seat will feedback a signal to the two-channel PNP optoelectronic signal module X2. After being converted by the two-channel PNP optoelectronic signal module, the signal current (10 mA) flows through the power relays J1, J3, J5, and J7. At this time, when the signal current (10 mA) flows through the power relays, the power relays J1, J3, J5, and J7 are energized. After the power relays are energized, the charging current (280 A) flows from the European standard charging socket through the power relays to the battery pack to complete the charging. At this time, since there is no signal current (10 mA) flowing through the power relays connected to the national standard charging sockets, the power relays J2, J4, J6, and J8 are in the off state, so the 1# national standard charging socket and the 2# national standard charging socket connected to these power relays are in the power-off state.

[0051] Specifically, referring to Figures 1-6 , the +Z1 of the 1# European standard charging socket is connected to the 1st position of the power relay J1, and the -Z5 of the 1# European standard charging socket is connected to the 2nd position of the power relay J5; the +Z2 of the 1# national standard charging socket is connected to the 1st position of the power relay J2, and the -Z6 of the 1# national standard charging socket is connected to the 2nd position of the power relay J6.

[0052] In this embodiment, the +Z1 of the 1# European standard charging socket is connected to the 1st position of the power relay J1, and this connection ensures that the positive pole of the European standard charging socket controls the current through the relay J1, making the current management during the charging process safer and more reliable;

[0053] Furthermore, the -Z5 of the 1# European standard charging socket is connected to the 2nd position of the power relay J5, and this connection ensures that the negative pole of the European standard charging socket controls the current through the relay J5, further ensuring the safety and stability of the charging process;

[0054] Even further, the +Z2 of the 1# national standard charging socket is connected to the 1st position of the power relay J2, and this connection ensures that the positive pole of the national standard charging socket controls the current through the relay J2, enabling good current management during the national standard charging process as well;

[0055] The -Z6 of the 1# national standard charging socket is connected to the 2nd position of the power relay J6, and its connection method ensures that the negative pole of the national standard charging socket controls the current through the relay J6, further enhancing the safety of the national standard charging process.

[0056] Specifically, referring to Figures 1-6, The positive terminal +Z3 of the 2# European standard charging socket is connected to the 1st position of the power relay J3, the negative terminal -Z7 of the 2# European standard charging socket is connected to the 2nd position of the power relay J7, the positive terminal +Z4 of the 2# national standard charging socket is connected to the 1st position of the power relay J4, and the negative terminal -Z8 of the 2# national standard charging socket is connected to the 2nd position of the power relay J8.

[0057] In this embodiment, during actual use, since the positive terminal +Z3 of the 2# European standard charging socket is connected to the 1st position of the power relay J3, this connection ensures that the positive electrode of the European standard charging socket controls the current through the relay J3, making the current management during the charging process safer and more reliable; at the same time, the negative terminal -Z7 of the 2# European standard charging socket is connected to the 2nd position of the power relay J7, and this connection ensures that the negative electrode of the European standard charging socket controls the current through the relay J7, further ensuring the safety and stability of the charging process;

[0058] Furthermore, the positive terminal +Z4 of the 2# national standard charging socket is connected to the 1st position of the power relay J4, and this connection ensures that the positive electrode of the national standard charging socket controls the current through the relay J4, enabling good current management during the national standard charging process as well; the negative terminal -Z8 of the 2# national standard charging socket is connected to the 2nd position of the power relay J8, and this connection ensures that the negative electrode of the national standard charging socket controls the current through the relay J8, further enhancing the safety of the national standard charging process.

[0059] Specifically, referring to Figures 1-6 , the 2nd positions of the power relay J1 and the power relay J2 are connected in series and then connected to the positive electrode 1 of the charging port, the 2nd positions of the power relay J3 and the power relay J4 are connected in series and then connected to the positive electrode 2 of the charging port, the power relay J5 and the power relay J6 are connected in series and then connected to the negative electrode 1 of the charging port, and the power relay J7 and the power relay J8 are connected in series and then connected to the negative electrode 2 of the charging port.

[0060] In this embodiment, when the power relay is energized, the charging current (280A) flows from the European standard charging socket through the power relay to the battery pack to complete the charging. At this time, since there is no signal current (10mA) flowing through the power relays connected to the national standard charging socket, then the power relay J2, the power relay J4, the power relay J6, and the power relay J8 are in the off state, so the 1# national standard charging socket and the 2# national standard charging socket connected to this power relay are in the power-off state.

[0061] Specifically, referring to Figures 1-6, the two-way PNP optoelectronic signal module interfaces K2-4 are respectively connected to power relays J2, J4, J6, and J8; the two-way PNP optoelectronic signal module interface K2-2 is connected to power relays J1, J3, J5, and J7; the two-way PNP optoelectronic signal module interfaces K1-4 are connected to power relays J1, J3, J5, and J7; the two-way PNP optoelectronic signal module interfaces K1-2 are connected to power relays J2, J4, J6, and J8.

[0062] In this embodiment, the PNP optoelectronic signal module can be used to transmit and control electrical signals. When the optoelectronic signal module detects a specific state, it can drive the power relay through the PNP output signal to control the on and off of the current.

[0063] Specifically, when in use: The PNP optoelectronic signal module interface K2-4 is connected to power relays J2, J4, J6, and J8. When the optoelectronic signal module at the K2-4 interface detects a specific signal, it will activate power relays J2, J4, J6, and J8. These relays will control the current of the corresponding charging seats, enabling these charging seats to be controlled simultaneously.

[0064] Furthermore, the PNP optoelectronic signal module interface K2-2 is connected to power relays J1, J3, J5, and J7. When the optoelectronic signal module at the K2-2 interface detects a specific signal, it will activate power relays J1, J3, J5, and J7. These relays will control the current of another group of charging seats to ensure charging control under different conditions.

[0065] Specifically, referring to Figures 1-6 , the European standard charging socket includes a No. 1 national standard charging socket and a No. 2 European standard charging socket; the No. 1 national standard charging socket is far from the No. 2 national standard charging socket and is distributed on the left and right sides of the battery pack. The No. 1 national standard charging socket is adjacent to the No. 1 European standard charging socket, and the No. 2 national standard charging socket is adjacent to the No. 2 European standard charging socket.

[0066] In this embodiment, as shown in Embodiment Figure 3 , in actual use, since two European standard charging seats and two national standard charging seats are each arranged, when two European standard sockets are connected simultaneously, the battery pack can be charged simultaneously. When two national standard sockets are connected simultaneously, the battery pack can be charged simultaneously.

[0067] Specifically, referring to Figure 4, the 2nd pin of the wire threading connector female seat is the national standard charging handshake signal, which is connected to X1 of the two-way PNP optoelectronic signal module;

[0068] The 3rd pin of the wire threading connector female seat is the European standard charging handshake signal, which is connected to X2 of the two-way PNP optoelectronic signal module;

[0069] The 6th pin of the wire threading connector female seat is DC0V, which is connected to the GND and K2-3 of the two-way PNP optoelectronic signal module;

[0070] The 7th pin of the wire threading connector female seat is DC24V. After passing through the fuse box F1, it is connected to the VCC and K1-3 of the two-way PNP optoelectronic signal module.

[0071] In this embodiment, by connecting the European standard charging handshake signal to the X2 interface of the PNP optoelectronic signal module, it is ensured that the charging handshake signal can be accurately transmitted to the control module, realizing the startup and communication confirmation of the charging process. This connection enables the charging device to perform necessary protocol exchanges, ensuring the compatibility and correctness of charging;

[0072] Furthermore, the ground wire is connected to the GND and K2-3. This connection ensures the ground wire connection of the optoelectronic signal module, maintaining the stability of the circuit and the correct potential reference.

[0073] Even further, by connecting the 24V power supply to the VCC and K1-3, when the 24V power supply passes through the fuse box F1, it is connected to the VCC and K1-3 of the PNP optoelectronic signal module, ensuring the power supply safety of the optoelectronic signal module. The fuse box F1 can disconnect the circuit when the current is too large, preventing device damage and enhancing the safety and reliability of the system.

[0074] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
