Description

The boost module is a newly developed functional device for 800V new energy vehicles.

Detailed Implementation

[0061] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] An integrated Boost converter module structure, such as Figure 1 As shown, it includes a high-voltage plug 2, a fast-charging socket 9, a battery socket 12, and an integrated module; wherein the fast-charging socket 9 and the battery socket 12 are fixedly connected to a fast-charging copper busbar 11, the integrated module is connected to the high-voltage plug 2, and both the fast-charging socket 9 and the battery socket 12 are connected to the integrated module.

[0063] The integrated module includes a first relay 3, a second relay 4, and a third relay 20. The positive terminal of the fast charging socket 9 is connected to the second relay 4, while the negative terminal is electrically connected to the filter component 14. The second relay 4 is connected to the filter component 14, and then the filter component 14 is connected in parallel with a fourth capacitor 15. The positive terminal of the fourth capacitor 15 is connected to an inductor 16, and the negative terminal of the fourth capacitor 15 is connected to the third relay 20. Then the inductor 16 is connected in series with the first relay 3. Both the first relay 3 and the third relay 20 are electrically connected to the high-voltage plug-in 2.

[0064] It should be noted that, in Figure 1The boost module structure also includes a control board 17 and a shielding plate 18, wherein the control board 17 is mounted on the shielding plate 18, and the shielding plate 18 is fixedly connected to the inductor 16. The function of the shielding plate 18 is to separate the control board 17 from the high-voltage inductor and prevent the low-voltage signal of the control board 17 from being interfered with.

[0065] It should be noted that the integrated Boost converter module has both fast charging and normal charging modes. In fast charging mode, charging is achieved through battery socket 12, while in normal mode, the high-voltage power is transmitted to the motor and electronic control unit via high-voltage plug 2. The motor and electronic control unit then supply high-voltage electricity to the battery pack for charging. The integrated module is installed in a remote and narrow space that is difficult to utilize in the vehicle, saving on overall wiring distance. Furthermore, it features a simple structure, high integration, compact layout, simple assembly process, high reliability, material savings, and low cost. It also uniquely utilizes an angled mounting plug, solving the significant problem of poor straight-face wiring on the vehicle.

[0066] Furthermore, combined Figure 1 and Figure 2 It can be seen that a fast charging copper busbar 11 is fixedly connected between the fast charging socket 9 and the battery socket 12; specifically, the positive and negative terminals of the fast charging socket 9 are respectively connected to a fast charging copper busbar 11, and the two fast charging copper busbars 11 are then connected to the positive and negative terminals of the battery socket 12 respectively.

[0067] Furthermore, combined Figure 1 and Figure 2 It can be seen that the positive and negative terminals of the fast charging copper busbar 11 are respectively connected to the first boost copper busbar 1101. One first boost copper busbar 1101 is fixedly connected to the second relay 4, and the other boost copper busbar 1101 is connected to the filter component 14. Specifically, there are two first boost copper busbars 1101, which are respectively connected to the two fast charging copper busbars 11. The positive first boost copper busbar 1101 is connected to the second relay 4, and the negative first boost copper busbar 1101 is connected to the filter component 14.

[0068] Furthermore, combined Figure 1 and Figure 2 It can be seen that a second boost copper busbar 1401 is fixedly connected between the second relay 4 and the filter component 14; specifically, one positive terminal and one negative terminal of the second relay 4 are respectively connected to a second boost copper busbar 1401, and then the positive and negative terminals of the input terminal of the filter component 14 are respectively connected to the second boost copper busbar 1401.

[0069] It should be noted that the first relay 3, the second relay 4, and the third relay 20 are generally equipped with multiple sets of positive and negative terminals.

[0070] Furthermore, a fifth single-pole copper busbar 25 is fixedly connected between the filter component 14 and the inductor 16, and a fourth single-pole copper busbar 24 is fixedly connected between the filter component 14 and the third relay 20. Specifically, the fifth single-pole copper busbar 25 is the positive terminal, and the fourth single-pole copper busbar 24 is the negative terminal. The positive terminal of the fourth capacitor 15 is fixedly connected to the middle section of the fifth single-pole copper busbar 25, and the negative terminal is fixedly connected to the middle section of the fourth single-pole copper busbar 24. Therefore, the fourth capacitor 15 and the filter component 14 are connected in parallel.

[0071] Furthermore, a second single-pole copper busbar 22 is fixedly connected between the inductor 16 and the first relay 3, a first single-pole copper busbar 21 is fixedly connected between the high-voltage plug 2 and the third relay 20, and a third single-pole copper busbar 23 is fixedly connected between the high-voltage plug 2 and the first relay 3.

[0072] Furthermore, such as Figure 2 As shown, the integrated Boost converter module structure also includes a housing 5, in which the high-voltage plug 2, fast charging socket 9 and battery socket 12 are all mounted on the surface of the housing 5. The fast charging socket 9 is inclined relative to the surface of the housing 5. In addition, the first relay 3, the second relay 4, the filter component 14, the fourth capacitor 15, the inductor 16 and the third relay 20 are all mounted inside the housing 5.

[0073] like Figure 1 and Figure 3 As shown, the fast charging copper busbar 11 is connected to the fast charging socket 9 via screw 19, and the first single-pole copper busbar 21 is also connected to the third relay 20 via screw 19.

[0074] Furthermore, a low-voltage signal plug-in 6 is installed on the housing 5, and the low-voltage signal plug-in 6 is set at an angle relative to the surface of the housing 5.

[0075] like Figure 4 As shown, two inclined surfaces are provided on the housing 5, which are used to install the low-voltage signal plug 6 and the fast charging socket 9 respectively. This allows the plug that matches the socket to exit at an angle, making it easier for the vehicle to route the wires. Furthermore, by tilting the housing 5 so that the inclined surfaces of the housing 5 are parallel to the paper, the space occupied by the wiring harness is greatly reduced, and the possibilities for the overall vehicle layout are greatly increased.

[0076] Furthermore, the housing 5 is fitted with a water nozzle 7.

[0077] It should be noted that a uniform and thick layer of thermal grease is applied to the bottom of the inductor 16, and then the inductor 16 is bolted to the aluminum housing 5. The vehicle supplies coolant to the housing 5 through the inlet and outlet water nozzles 7. The housing 5 has cooling water channels, and the coolant will enter the cooling water channels to dissipate heat from the inductor 16. Finally, the first cover plate 1 is bolted to the housing 5, and the second cover plate 13 is bolted to the first cover plate 1, completing the assembly of the entire Boost boost module.

[0078] It should be noted that the shell 5 is designed with a unique long and flat shell shape, which makes full use of the narrow space under the vehicle body that is not easily utilized, reducing the complexity of the vehicle wiring and the length of the wiring harness.

[0079] Furthermore, combined Figure 1 and Figure 4 It can be seen that the housing 5 is equipped with a grounding connector 8, which is used to connect the grounding wire and play a protective role.

[0080] Furthermore, a vent valve 10 is also installed on the surface of the housing 5. The function of the vent valve 10 is to prevent water, dust, and oil stains, prevent condensation and fogging, and also to dissipate heat and maintain a stable pressure difference.

[0081] like Figure 5 and Figure 6 The structural diagram of the filter assembly 14 shown illustrates that the frame of the filter assembly 14 includes a plastic support base 14d and a filter plate 14f, which are fixedly connected by bolts. The support base 14d has an inner cavity, and a filter copper busbar 14c is installed within this cavity. Magnetic rings 14b are symmetrically installed at both ends of the filter copper busbar 14c, resulting in two magnetic rings 14b. Magnetic ring cover plates 14a are installed on the surface of each magnetic ring 14b. Finally, the plastic support base 14d is connected to the housing 5 by fastening bolts 14e. The filter plate 14f also houses a first capacitor 14g, a second capacitor 14h, and several third capacitors 14i (generally two). In operation, the filter plate 14f receives power from the fast-charging copper busbar 14g. The introduced current first flows to the filter copper busbar 14c, then passes through the magnetic ring 14b, filtering out a layer of electromagnetic interference signal. After passing through the magnetic ring 14b, the current signal is filtered again by the filter board 14f soldered to the pins of the filter copper busbar 14c. The filter board 14f consists of two third capacitors 14i (220nF Y capacitors), one first capacitor 14g (0.22uf X capacitor), and one second capacitor 14h (3.3uf X capacitor). After being filtered by the filter board 14f, the current passes through the magnetic ring 14b again. The entire circuit is an LCL electromagnetic circuit (capacitor magnetic ring circuit). The interference signal is greatly reduced by the two-stage filter components 14.

[0082] It should be noted that the filter board 14f structure, because it is installed on the pins of the filter copper busbar 14c, can not only meet the electrical performance of the LCL filter circuit, but also meet the structural requirements of the magnetic ring 14b and the magnetic ring cover plate 14a.

[0083] like Figure 7The diagram of the inductor 16 shows that the inductor core 16c is installed into the inductor plastic frame 16b, and then the coil 16f is wound around the outer ring of the inductor frame 16b. The copper busbar 16d is fastened to the inductor frame 16c by the connecting stud 16g. The entire inductor is then placed in the inductor aluminum shell 16a. Finally, sealant 16e is poured into the inductor aluminum shell 16a, resulting in a new type of inductor with precise mounting and positioning holes and the ability to handle large currents.

[0084] like Figure 8 The diagram shown is a circuit diagram of the integrated Boost converter module structure of the present invention, specifically including a power battery unit, a motor controller, a Boost converter module, and a charging pile unit.

[0085] The power battery unit is an on-board battery, consisting of several batteries connected in series. The charging pile unit is a charging pile connected to the power battery unit via line A and line B. In fast charging mode, the switches on line A and line B are closed, while K1, K2 and K3 in the Boost boost module are disconnected, and then the charging pile directly charges the power battery unit.

[0086] In the Boost module, line C and line D are connected to the charging pile. A switch K2 (corresponding to the second relay 4) is connected in series on line C, and a switch K3 (corresponding to the third relay 20) is connected in series on line D. Then, both line C and line D are connected to the filter component 14. The filter component 14 is then connected in parallel with a capacitor C2 (corresponding to the fourth capacitor 15). The positive terminal of capacitor C2 is connected in series with an inductor L1 (corresponding to inductor 16) and a switch K1 (corresponding to the first relay 3). Then, switch K1 is connected to the motor, and the motor is connected to the motor controller. At the same time, the negative terminal of capacitor C2 is also connected to the motor controller.

[0087] Combination Figure 8 and Figure 9 The filter component 14 consists of four parallel branches. Starting from the right, the first branch has a capacitor C3 (corresponding to the first capacitor 14g, i.e., a 0.22ufX capacitor). The two ends of capacitor C3 are connected to line C and line D, and connected to switches K2 and K3. The second and fourth branches have magnetic rings L3 and L2, respectively. Magnetic ring L2 is connected in parallel with capacitor C2. Furthermore, a protective grounding wire, i.e., PGND, is connected between switch K3 and magnetic ring L3. The third branch has a capacitor C6 (corresponding to the second capacitor 14h, i.e., a 3.3ufX capacitor). In addition, the two ends of the third branch are connected to grounding branches. On the grounding branches at both ends, capacitors C5 and C4 (corresponding to the third capacitor 14i, i.e., two 220nF Y capacitors) are respectively installed. Then, capacitors C5 and C4 are respectively connected to grounding wires, i.e., GND.

[0088] It should be noted that the motor controller consists of a parallel capacitor C1, a thyristor, and a filter assembly 14, and then the motor controller is connected to the power battery unit.

[0089] The specific embodiments of the present invention are described below:

[0090] The charging and discharging schematic of the entire Boost converter module is shown in the image. Figure 8 As shown, the entire Boost module obtains current through an external charging station. When the voltage of the external charging station is higher than the battery voltage, it directly supplies power to the power battery unit through the fast charging circuit. When the voltage of the external charging station is lower than the battery voltage, it provides boost power to the three-in-one control module through the Boost module.

[0091] During operation, the fast charging socket 9 is connected to an external charging station via a high-voltage cable to supply power to the Boost converter module. When the voltage of the external charging station is higher than the battery voltage, direct fast charging is initiated, and the first relay 3, the second relay 4, and the third relay 20 are closed, i.e., the charging mode is activated. Figure 8 When K1, K2, and K3 are open, and K4 and K5 are closed, current flows through the fast-charging copper busbar 11 to output a large current of 340A to the 95mm IPT battery socket 12, thereby achieving fast charging of the battery. When the voltage of the external charging pile is lower than the battery voltage, the Boost fast charging mode is activated. Figure 8 Relays K1, K2, and K3 are closed, while K4 and K5 are open. The 107A boost current draws power from the fast-charging copper busbar 11 through the boost copper busbar 2, passes through the second relay 4, and then to the EMC (electromagnetic compatibility) filter component 14. It then passes through the fourth capacitor 15 and is shunted. The positive circuit current passes through the inductor 16 and then to the first relay 3. The negative circuit current passes through the first single-pole copper busbar 21 and is directly input to the third relay 20. Finally, the current converges to the 25-square-meter high-voltage plug-in 2 and is output to the vehicle motor and electronic control system.

[0092] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
