[0033] The controller assembly 10 includes a housing assembly 100, a power distribution assembly 200, a motor control assembly 300, and an integrated power supply assembly 400. The power distribution assembly 200 is disposed within the housing assembly 100 and includes a bus element 210 and a first filter element 220. The first filter element 220 is electrically connected to the battery through the bus element 210. The motor control assembly 300 is disposed within the housing assembly 100 and includes a motor controller 310 and a second filter element 320. The second filter element 320 is connected to the first filter element 220 and the motor controller 310. The motor controller 310 is electrically connected to the motor; the integrated power supply assembly 400 is disposed within the housing assembly 100. The integrated power supply assembly 400 includes a first power distribution element 410 and a third filter element 420. The first power distribution element 410 is electrically connected to an external power source. The third filter element 420 is electrically connected to the first power distribution element 410 and the second filter element 420, respectively, so that when the battery is charging and discharging, the first filter element 220, the second filter element 320 and the third filter element 420 filter the electrical signals in the circuit between the external power source and the battery.

[0034] The housing assembly 100 has a receiving space to accommodate electrical components in the controller assembly 10.

[0035] The power distribution assembly 200 is disposed within the housing assembly 100 and can be used to connect a battery. Specifically, the power distribution assembly 200 may include a bus element 210 and a first filter element 220. The bus element 210 includes a bus interface that penetrates the outer shell of the housing assembly 100 for electrical connection with the battery. The end of the bus element 210 away from the bus interface is electrically connected to the first filter element 220. The battery transmits high-voltage direct current (HVDC) to the controller assembly 10 through the bus interface. This HVDC has high-frequency harmonics and voltage spikes. The HVDC passes sequentially through the bus element 210, the first filter element 220, and other electrical components. The first filter element 220 can filter out the high-frequency harmonics and voltage spikes of the current on the bus element 210 and can reduce high-frequency electromagnetic waves that negatively affect the battery, thereby improving power quality. The first filter element 220 may be a choke or a capacitor.

[0036] The motor control assembly 300 is disposed within the housing assembly 100. The motor control assembly 300 may include a motor controller 310 and a second filter element 320. The second filter element 320 is electrically connected to both the first filter element 220 and the motor controller 310, and can further filter the electricity conducted by the power distribution assembly 200. Specifically, the motor controller 310 may include an IGBT (Insulated Gate Bipolar Transistor) and a three-phase copper busbar. The IGBT is connected to both the second filter element 320 and the three-phase copper busbar. The IGBT converts the DC power conducted by the second filter element 320 into AC power, which is then conducted to the motor by the three-phase copper busbar. The motor utilizes the AC power and converts it into mechanical energy to power the vehicle. The second filter element 320 stabilizes the DC power conducted by the power distribution assembly 200, reducing voltage fluctuations and minimizing the damage to the battery caused by electromagnetic waves with high voltage fluctuations. Furthermore, when the motor controller 310 is stopped, the second filter element 320 can release stored electrical energy, improving the system safety of the controller assembly 10. The second filter element 320 may be an electrolytic capacitor or / and a film capacitor. The motor control assembly 300 may also include an electric drive resolver controller, which can be electrically connected to the motor via a resolver interface to provide signal communication and control the position, speed and direction of rotation of the motor rotor.

[0037] An integrated power supply assembly 400 is also disposed within the housing assembly 100. The integrated power supply assembly 400 may include a first power distribution element 410 and a third filter element 420. The first power distribution element 410 is used to connect to an external power source, and the third filter element 420 is electrically connected to both the first power distribution element 410 and the second filter element 420. The first power distribution element 410 may include a slow-charging interface, which is electrically connected to an external power source with alternating current (AC) to charge the battery. The first power distribution element 410 is also electrically connected to the third filter element 420, thereby filtering high-frequency electromagnetic waves carried by the AC power, thus reducing damage to the battery. The third filter element 420 may be an electromagnetic interference (EMI) filter. During battery charging, the first power distribution element 410 is electrically connected to an external power source, and the bus element 210 is electrically connected to the battery. Three filter elements are installed between the bus element 210 and the first power distribution element 410 to charge the battery. The charging current passes sequentially through the third filter element 420, the second filter element 320, and the first filter element 220, allowing the three filter elements to reduce the damage to the battery caused by electromagnetic waves generated by each component. During battery discharging, the current from the battery passes sequentially through the first filter element 220, the second filter element 320, and the third filter element 420, further reducing the damage to the battery caused by electromagnetic waves generated by each component during discharge. Furthermore, the third filter element 420 can also reduce high-frequency electromagnetic waves to minimize harm to the human body.

[0038] Through the above embodiments, the first filter element 220, the second filter element 320 and the third filter element 420 are respectively disposed in the power distribution assembly 200, the motor control assembly 300 and the integrated power supply assembly 400, so that during the charging and discharging process of the battery, the first filter element 220, the second filter element 320 and the third filter element 420 can work together to reduce the damage of electromagnetic waves to the battery in multiple ways.

[0039] In some embodiments, the integrated power supply assembly 400 includes a converter assembly 430, which includes an inductor (not shown). A third filter element 420 is disposed in the converter and is electrically connected to both the second filter element 320 and the inductor. The integrated power supply assembly 400 supplies power to the vehicle's low-voltage equipment via the inductor. The converter assembly 430 can convert higher-voltage DC to any voltage DC via the inductor; that is, it can convert the voltage of the current being converted, for example, converting the high-voltage DC conducted from the battery pack to a lower-voltage DC, thereby supplying power to the vehicle's low-voltage equipment. The third filter element 420 can be disposed in the converter assembly 430 and can be electrically connected to both the inductor and the second filter element 320, as well as to the inductor and the first power distribution element 410. Therefore, during battery charging, the third filter element 420 can filter the voltage-converted current to reduce damage to the battery. In addition, the inductor is also electrically connected to the vehicle's low-voltage equipment. Thus, when the battery is discharging, the third filter element 420 can first filter the current from the battery. The filtered current is then conducted to the inductor. Finally, the inductor can conduct the reduced voltage and the filtered current through the low-voltage interface to the low-voltage equipment for its operation, thereby reducing interference to the low-voltage equipment.

[0040] In some embodiments, the integrated power supply assembly 400 further includes a temperature control assembly 440, which includes a heating controller 441. The heating controller 441 is electrically connected to the third filter element 420 and the vehicle's heating equipment. Since pure electric vehicles do not have an engine, their heating function cannot be provided by the engine like traditional fuel vehicles. Therefore, the integrated power supply assembly 400 includes a temperature control assembly 440, which includes a heating controller 441. The heating controller 441 is electrically connected to the third filter element 420 and the vehicle's heating equipment. When the battery is discharging, the current from the battery can pass through the third filter element 420. After the third filter element 420 eliminates some electromagnetic waves, the current can then supply power to the heating equipment through the heating control interface, thereby reducing electromagnetic interference to the heating equipment. The heating equipment can be an air conditioner, seats, or battery, etc., to achieve the functions of heating the vehicle interior environment, heating the seats, and preheating the battery. Furthermore, integrating the heating controller 441 into the integrated power supply assembly 400 can reduce the complexity of the wiring harness, reduce the number of components, simplify the wiring, and reduce costs.

[0041] In some embodiments, the temperature control assembly 440 further includes a cooling controller 442, which is electrically connected to the third filter element 420 and the vehicle's gas compression equipment. The cooling controller 442 is electrically connected to the vehicle's gas compression equipment, which draws in low-temperature, low-pressure gaseous refrigerant from the low-pressure side, compressing it to increase its temperature and pressure, and then pumping it into the high-pressure side to become high-temperature, high-pressure gaseous refrigerant. This cycle repeats, achieving heat exchange between the external environment and the vehicle system. The cooling controller 442 is also electrically connected to the third filter element 420, so that when the battery discharges, the current from the battery can first pass through the third filter element 420. After the third filter element 420 eliminates some electromagnetic waves, the current can then supply power to the gas compression equipment through the cooling control interface of the cooling controller 442, thereby reducing electromagnetic interference to the gas compression equipment. Integrating the cooling controller 442 into the integrated power supply assembly 400 also reduces the complexity of the wiring harness, reduces the number of components, simplifies the wiring, and reduces costs. Furthermore, incorporating the temperature control component 440 into the integrated power supply component 400 reduces the number of separate heating devices and controllers for charging, thereby lowering costs.

[0042] Furthermore, in some embodiments, the integrated power supply assembly 400 may also include an on-board charging assembly, which can be electrically connected to the first power distribution element 410 and the converter assembly 430 respectively. The on-board charging assembly can convert AC power conducted by an external power source connected to the first power distribution element 410 into DC power, and can also adjust the charging current and voltage parameters to perform protective charging of the battery. Thus, the integrated power supply assembly 400 includes an on-board charging assembly, a converter assembly 430, and a temperature control assembly 440, allowing them to cooperate to optimize battery charging scenarios. For example, in low-temperature scenarios, the battery can be preheated by a heating controller 441; in high-temperature scenarios, the battery can be cooled by a cooling controller 442, providing a basic configuration for multiple charging modes. Integrating the temperature control assembly 440 into the integrated power supply assembly 400 reduces the number of independent heating devices and controllers used for charging, thereby reducing costs.

[0043] In some embodiments, the integrated power supply assembly 400 is disposed adjacent to the motor control assembly 300, with the converter assembly 430 positioned closer to the motor control assembly 300. The integrated power supply assembly 400 includes various components, with the converter assembly 430 used to convert high-voltage direct current into low-voltage direct current to charge the battery. The converter assembly 430 is also electrically connected to the battery via the motor control assembly 300 and the power distribution assembly 200. Therefore, positioning the converter assembly 430 closer to the motor control assembly 300 relative to other components allows for a shorter electrical connection between the converter assembly 430 and the battery, thereby optimizing the circuitry and reducing its complexity.

[0044] In some embodiments, the controller assembly 10 further includes a heat dissipation channel 500. The temperature control component 440 and the converter component 430 respectively include a temperature control drive board 443 and a converter drive board 432. The temperature control drive board 443, the converter drive board 432, and the motor controller 310 are sequentially arranged on the path of the heat dissipation channel 500 from the inlet to the outlet. The temperature control component 440 includes a temperature control drive board 443, the converter component 430 includes a converter drive board 432, and the motor control component 300 includes a motor controller 310. Since the temperature control drive board 443, the converter drive board 432, and the motor controller 310 will carry a large current, they will generate heat. To dissipate heat, a cooling channel 500 is provided in the controller assembly 10. The cooling channel 500 has an inlet and an outlet. Since the temperature control drive board 443 generates less heat than the converter drive board 432 and the motor controller 310, and the motor controller 310 generates more heat, the temperature control drive board 443, the converter drive board, and the motor controller 310 are arranged sequentially along the path of the cooling channel 500, that is, the temperature control drive board 443 is closer to the inlet and the motor controller 310 is closer to the outlet, thereby making the cooling channel 500 more efficient in dissipating heat.

[0045] In some embodiments, the cooling channel 500 includes an annular channel 510 and a straight channel 520, which are connected. The temperature control drive board 443 and the converter drive board 432 are sequentially arranged circumferentially around the path of the annular channel 510, and the motor controller 310 is disposed on the path of the straight channel 520. Since the converter assembly 430 has a large number of components and a large distribution interval, while the motor control assembly 300 is relatively simple, the cooling channel 500 is divided into an annular channel 510 and a straight channel 520. The temperature control drive board 443 and the converter drive board 432 are arranged at intervals, so that the annular channel 510 is disposed between the temperature control drive board 443 and the converter drive board to accommodate the distribution structure of the temperature control assembly 440 and the converter assembly 430. Designing a part of the cooling channel 500 as an annular channel can also increase the path of the cooling channel 500 to provide more heat dissipation points and fully dissipate heat for the integrated power supply assembly 400. In addition, the integrated power supply assembly 400 also includes an on-board charging assembly, which includes an on-board charging drive board. An annular water channel 510 can also be located in the gap between the temperature control drive board 443, the converter drive board 432, and the on-board charging drive board to dissipate heat from the integrated power supply assembly 400. Since the motor controller 310 has a relatively simple structure and generates a large amount of heat, a simple straight water channel 520 is used to dissipate heat from the motor controller 310. The straight water channel 520 has a shorter path, thus removing the heat from the motor controller 310 more quickly. Therefore, this arrangement can further improve the heat dissipation efficiency of the cooling water channel 500. The number of converter drive boards 432 and on-board charging drive boards can be multiple.

[0046] In some embodiments, the housing assembly 100 includes a first housing 110 and a second housing 120. The first housing 110 is used to house the power distribution assembly 200, and the second housing 120 is used to house the motor control assembly 300 and the integrated power supply assembly 400. The power distribution assembly 200 includes a second power distribution element 230, and a first filter element 220 and the second power distribution element 230 are arranged vertically. The first housing 110 and the second housing 120 are arranged adjacent to each other, and each has a receiving space. The receiving space of the first housing 110 accommodates the power distribution assembly 200, and the receiving space of the second housing 120 accommodates the motor control assembly 300 and the integrated power supply assembly 400. The power distribution assembly 200 includes a first filter element 220 and a second power distribution element 230. The second power distribution element 230 is connected to an external high-voltage DC power supply and is directly electrically connected to the bus element 210, thereby allowing the battery to be quickly charged through the second power distribution element 230. In the first housing 110, the second power distribution element 230, the first filter element 220, and the bus element 210 are arranged vertically, which can make full use of the space inside the second housing 120, thereby improving space utilization and reducing the volume of the housing assembly 100.

[0047] In some embodiments, the controller assembly 10 includes a main controller (not shown) and a main control board 600, both located in the second housing 120. The main controller, motor control component 300, and integrated power supply component 400 are all integrated on the main control board 600. The main controller controls the motor control component 300 and the integrated power supply component 400 through the control circuit of the main control board 600. The integration of the motor control component 300 and the integrated power supply component 400 on the main control board 600 shortens the transmission path between components and utilizes the control circuit within the main control board 600 to replace wiring harness connections, thus improving equipment reliability. Furthermore, the main controller is also integrated on the main control board 600. The main controller is electrically connected to the motor control component 300 and the integrated power supply component 400 through the control circuit on the main control board 600, thereby fully utilizing the size of the main control board 600. This eliminates the complex interconnection method of independent control of multiple components using wiring harnesses in traditional designs, achieving efficient utilization of control components and improving the reliability and economy of control communication. In addition, the controller assembly 10 also has a vehicle controller, which is also integrated on the main control board 600 and electrically connected to the main controller through the control circuit on the main control board 600 to realize the control of the whole vehicle, such as the control of the motor torque, the low voltage and high voltage power supply of the whole vehicle, energy recovery, etc.

[0048] In summary, the first filter element 220, the second filter element 320, and the third filter element 420 are respectively disposed in the power distribution assembly 200, the motor control assembly 300, and the integrated power supply assembly 400, so that during the charging and discharging process of the battery, the first filter element 220, the second filter element 320, and the third filter element 420 can work together to reduce the damage of electromagnetic waves to the battery in multiple ways.
