[0033] like Figure 1-Figure 5 As shown, this embodiment provides an all-in-one controller for an electric vehicle, comprising a high-voltage power distribution module 100, a motor controller module 200, a power module 300, a partition assembly 500, and a box assembly 400. The high-voltage power distribution module 100, the motor controller module 200, the power module 300, and the partition assembly 500 are all disposed within the box assembly 400. The first direction is the X direction, the second direction is the Y direction, and the third direction is the Z direction. The first direction, the second direction, and the third direction are arranged at an angle to each other. In this embodiment, the first direction, the second direction, and the third direction are perpendicular to each other.

[0034] The high-voltage distribution module 100 includes a terminal block assembly 110 and a circuit board assembly 120. Specifically, the terminal block assembly 110 includes a terminal block 111, a second conductive copper bus 112, a relay 113 and at least one fuse 114. The circuit board assembly 120 includes a high-voltage distribution circuit board 121 and at least one connector 122 for realizing the high-voltage distribution function.

[0035] The power module 300 includes an onboard charger (OBC) and a DC / DC converter, which are used to implement the vehicle's power management functions. The power module 300 has at least four first terminal mounting ports 310, and the high-voltage distribution circuit board 121 of the circuit board assembly 120 has at least four second terminal mounting ports 123. The first terminal mounting ports 310 and the second terminal mounting ports 123 correspond one-to-one and are connected by a wiring harness 800. The terminals at both ends of the wiring harness 800 are connected to the first terminal mounting ports 310 and the second terminal mounting ports 123 via screws, thereby achieving an electrical connection between the power module 300 and the high-voltage distribution module 100, and realizing power flow transfer between the high-voltage distribution module 100 and the power module 300.

[0036] The motor controller module 200 includes a filter 210, a drive motor control board 230, a power module 240, an AC wiring socket 250, and a bus capacitor 260, for implementing motor control functions. The filter 210, bus capacitor 260, power module 240, and AC wiring socket 250 are electrically connected in sequence. The drive motor control board 230 is connected to the power module 240. Specifically, the filter 210 and the input copper busbar 261 of the bus capacitor 260 are fixedly connected to each other via fasteners such as screws to achieve electrical connection, and the output copper busbar of the power module 240 is connected to the AC wiring socket 250 via fasteners such as screws to achieve electrical connection. The filter 210 has a first conductive copper busbar 211, and the second conductive copper busbar 112 of the wiring socket assembly 110 is connected to the first conductive copper busbar 211 via fasteners such as screws, thereby achieving electrical connection between the high-voltage distribution module 100 and the motor controller module 200, and realizing power flow transmission between the high-voltage distribution module 100 and the motor controller module 200.

[0037] The high-voltage distribution module 100 and the power supply module 300 are arranged along the first direction, and the high-voltage distribution module 100 and the power supply module 300 are both arranged on one side of the motor controller module 200 along the second direction. By modularizing the high-voltage distribution module 100, the power supply module 300 and the motor controller module 200, each module is assembled in parallel, and then multiple modules are assembled into an assembly, the assembly time is short and the efficiency is high, which solves the problem of low assembly efficiency. In the later maintenance stage, only the corresponding modules that need to be repaired are removed from the assembly for replacement or repair, and the difficulty of later maintenance is low. The removed modules are returned to the factory for repair separately, which does not affect the end customer's use of the vehicle, greatly improving flexibility and convenience. Through the above layout method, the internal space of the box assembly 400 is fully utilized, making the structure more compact.

[0038] The AC terminal block 250 and the filter 210 are both located on one side of the high-voltage distribution module 100 along the second direction. The AC terminal block 250 is isolated from the filter 210 and the high-voltage distribution module 100, and from the high-voltage distribution module 100 and the power module 300, respectively, by a partition assembly 500. Since AC power flows through the AC terminal block 250, the filter 210 and the high-voltage distribution module 100 are connected via DC power. The connection between the high-voltage distribution module 100 and the power module 300 includes both DC and AC power. The high-voltage distribution module 100 includes components for processing both DC and AC power, and the power module 300 includes components for processing both DC and AC power. Therefore, the partition assembly 500 can isolate the AC terminal block 250 from the DC portion of the high-voltage distribution module 100, isolate the AC terminal block 250 from the filter 210, isolate the DC portion of the high-voltage distribution module 100 from the AC portion of the power module 300, and isolate the AC portion of the high-voltage distribution module 100 from the DC portion of the power module 300. Furthermore, the above module layout facilitates the installation of the partition assembly 500, thereby effectively avoiding mutual electromagnetic interference between the AC and DC portions, and resolving the problem of poor electromagnetic compatibility.

[0039] The motor controller module 200 also includes a shielding plate 220. Specifically, the filter 210, shielding plate 220, drive motor control board 230, power module 240, and bus capacitor 260 are arranged in sequence along a first direction. The filter 210 is isolated from the drive motor control board 230 and power module 240 by the shielding plate 220. Since the drive motor control board 230 and power module 240 both process alternating current (AC) while the filter 210 processes DC, the shielding plate 220 isolates the filter 210 of the motor controller module 200 from the drive motor control board 230 and power module 240 in the first direction, preventing electromagnetic interference between the two and resolving electromagnetic compatibility issues.

[0040] Optionally, the motor controller module 200 further includes a heat sink 270 , which is disposed between the bus capacitor 260 and the power module 240 and is used to dissipate heat from the motor controller module 200 .

[0041] The motor controller module 200 further includes an AC wiring socket 250 . The AC wiring socket 250 and the filter 210 are disposed on the same side of the shielding plate 220 . The power module 240 is electrically connected to the AC wiring socket 250 .

[0042] Optionally, the output copper busbar of the power module 240 passes through the shielding plate 220 to be connected to the AC terminal block 250, and the input copper busbar 261 of the bus capacitor 260 passes through the shielding plate 220 to be connected to the filter 210. The shielding plate 220 is provided with a first avoidance hole 221 and a second avoidance hole 222. The output copper busbar passes through the first avoidance hole, and the input copper busbar 261 passes through the second avoidance hole 222.

[0043] The filter 210 and the AC terminal block 250 are arranged along the third direction; a first partition 510 is provided in the second box body 420, and the filter 210 and the AC terminal block 250 are both provided in the second box body 420, and are provided on both sides of the first partition 510 along the third direction. The filter 210 processes direct current, and the AC terminal block 250 processes alternating current. Therefore, by providing the first partition 510, isolation between the filter 210 and the AC terminal block 250 is achieved, mutual electromagnetic interference between direct current and alternating current is prevented, and the problem of electromagnetic compatibility between them is solved.

[0044] A second partition plate 520 is provided in the second box body 420 , and the AC wiring socket 250 and the high-voltage distribution module 100 are provided on both sides of the second partition plate 520 along the second direction.

[0045] The terminal block assembly 110 and the circuit board assembly 120 are stacked along a first direction. The circuit board assembly 120 is located on a side of the terminal block assembly 110 near the first housing 410. The circuit board assembly 120 is electrically connected to the power module 300. A third partition 530 is provided between the first housing 410 and the second housing 420. The circuit board assembly 120 and the power module 300 are electrically connected on both sides of the third partition 530 along the first direction. The third partition 530 isolates the DC portion of the circuit board assembly 120 from the AC portion of the power module 300, preventing mutual electromagnetic interference and addressing electromagnetic compatibility issues.

[0046] The housing assembly 400 includes a first cover plate 430, a first housing 410, a second housing 420, and a second cover plate 440, arranged in sequence along a first direction. The first housing 410 includes a first accommodating space and a second accommodating space, arranged along a second direction. The first accommodating space has a first opening 411, and the second accommodating space has a second opening 412. The first and second openings 411 and 412 have opposite opening directions. The second housing 420 has a third opening 421 and a fourth opening 422 at opposite ends along the first direction. The first and third openings 411 and 421 face each other and are connected. A partition plate is provided along the second direction to separate the first and second accommodating spaces. The first cover plate 430 is provided at the second opening 412, and the second cover plate 440 is provided at the fourth opening 422.

[0047] The high-voltage distribution module 100 can pass through the third opening 421 to be set in the second box body 420, the motor controller module 200 can pass through the first opening 411 and the third opening 421 to be set in the first accommodating space and the second box body 420, and the power supply module 300 can pass through the second opening 412 to be set in the second accommodating space.

[0048] By dividing the housing assembly 400 into a first housing 410 and a second housing 420, the first housing 410 is divided into a first accommodating space and a second accommodating space. The second housing 420 and the first accommodating space of the first housing 410 are connected through the first opening 411 and the third opening 421. This allows a portion of the space in the second housing 420 and the first accommodating space to be used to accommodate the motor controller module 200, the second accommodating space in the first housing 410 to be used to accommodate the power module 300, and the remaining space in the second housing 420 to be used to accommodate the high-voltage power distribution module 100. By rationally dividing the internal space of the housing assembly 400, the internal space is fully utilized, making the internal structure of the all-in-one controller more compact. The provision of the first opening 411, the second opening 412, and the third opening 421 facilitates assembly, further improving assembly efficiency.

[0049] Optionally, the assembly steps of the all-in-one controller include:

[0050] Step 1: The partition assembly 500, namely the first partition 510, the second partition 520 and the third partition 530, are pre-installed on the first box body 410 and the second box body 420 respectively, that is, the first partition 510 and the second partition 520 are installed in the second box body 420, and the first partition 510, the second partition 520 and the second box body 420 form an installation space connected at both ends along the first direction, and the third partition 530 is installed on the side of the first box body 410 away from the second opening 412 and facing the second box body 420.

[0051] Step 2: PCB assembly 120 is connected to one side of terminal block assembly 110 using fasteners. Shield plate 220, drive motor control board 230, power module 240, heat sink 270, and busbar capacitor 260 are stacked in sequence and secured together using screws and other fasteners. AC terminal block 250 is connected to power module 240. The onboard charger (OBC) and DC / DC converter within power module 300 are assembled. Steps 1 and 2 can be performed simultaneously or separately, with no specific order.

[0052] Step 3: The terminal block assembly 110 is connected to the second housing 420 via fasteners, and the high-voltage distribution module 100 is installed in the second housing 420. Specifically, the terminal block 111, the second conductive copper busbar 112, the relay 113, and the at least one fuse 114 are installed in the second housing 420. Then, the circuit board assembly 120 is installed in the second housing 420 or on the terminal block assembly 110.

[0053] The filter 210 is installed in the second housing 420. The filter 210 has mounting legs 212 connected to the second housing 420 via screws or other fasteners. The filter 210 is electrically connected to the terminal block assembly 110 of the high-voltage power distribution module 100.

[0054] The shielding plate 220, drive motor control board 230, power module 240, heat sink 270, busbar capacitor 260, and AC terminal block 250 are placed integrally within the second housing space. Heat sink 270 is connected to the first housing space via screws and other fasteners, while AC terminal block 250 is located outside the first housing space. Because motor controller module 200 comprises numerous components stacked in the first direction, the filter 210 and heat sink 270 are secured to the second housing 420 and the first housing space, respectively, ensuring stable installation.

[0055] Step 4: The first box body 410 and the second box body 420 are connected by screws and other fasteners, so that the AC terminal block 250 is set in the installation space of the second box body 420, the power module 300 and the high-voltage distribution module 100 are connected by the wiring harness 800, and then the first cover plate 430 is connected to the second opening 412 of the first box body 410 by screws.

[0056] Step 5: Electrically connect the filter 210 and the input copper busbar 261 of the bus capacitor 260 through the fourth opening 422 , and finally install the second cover plate 440 at the fourth opening 422 .

[0057] Optionally, the filter 210 and the terminal block assembly 110 of the high-voltage power distribution module 100 can also be electrically connected through the fourth opening 422 in the fifth step and assembled as required.

[0058] This embodiment also provides an electric vehicle including the aforementioned all-in-one controller. Due to the modular design of the all-in-one controller, when individual modules require repair at the factory, they can be replaced with new ones without affecting the use of the electric vehicle, thereby improving flexibility and convenience. Furthermore, the all-in-one controller offers the advantage of electromagnetic compatibility, thereby avoiding electromagnetic interference with the entire vehicle and enhancing the performance and reliability of the electric vehicle.
