Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] Terminology explanation:

[0030] ① New energy vehicle drive motor: refers to the electric motor used to drive new energy vehicles such as electric vehicles and hybrid vehicles. It is responsible for converting the electrical energy provided by the battery into mechanical energy, thereby driving the wheels of the new energy vehicle to rotate and realize vehicle acceleration, deceleration and driving.

[0031] ② Sequential utilization: refers to the process of reusing products that have been used but not completely invalid. It extends the product life cycle and utilization value by reconfiguring or downgrading. This method is particularly suitable for high value-added and high-tech products in electromechanical products.

[0032] ③ Remanufacturing: It refers to the process of giving new life to old machinery and equipment. It uses old machinery and equipment as blanks, adopts special processes and technologies, and conducts a new manufacturing on the basis of the original manufacturing. The remanufactured products are no less than new products in terms of performance and quality.

[0033] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Figures 1 to 5 The integrated system for remanufacturing and recycling of retired drive motors for new energy vehicles provided in an embodiment of the present application is described in detail.

[0035] Please refer to Figure 1 , which is a structural block diagram of an integrated system for remanufacturing and cascade utilization of retired drive motors of new energy vehicles provided in an embodiment of the present application. The integrated system 10 for remanufacturing and cascade utilization includes a classification subsystem 101, a remanufacturing subsystem 102, an application matching subsystem 103, and a full life cycle monitoring subsystem 104. Among them, the classification subsystem 101 can obtain the type of retired drive motors of new energy vehicles, and classify the retired drive motors of new energy vehicles according to the type. For example, the types include but are not limited to passenger car motors and commercial vehicle motors. Passenger car motors have the characteristics of high speed, high power density, high efficiency and high reliability, while commercial vehicle motors have the characteristics of high power, high torque and high overload capacity. The remanufacturing subsystem 102 can remanufacture the classified retired drive motors of new energy vehicles. For example, remanufacturing includes but is not limited to evaluation, disassembly, repair, reorganization, testing and quality control operations.

[0036] The application matching subsystem 103 can match the remanufactured retired new energy vehicle drive motor with the device to be combined, generate the target device, and test the performance indicators of the target device. For example, the application matching subsystem 103 can specifically detect the structure and control parameters of the device to be combined, and adjust the structure and control parameters of the remanufactured retired new energy vehicle drive motor based on the structure and control parameters of the device to be combined. The structure and control parameters include but are not limited to motor size, mechanical interface, heat dissipation method, control interface, drive characteristics and control strategy, etc., wherein the motor size adaptation can ensure that the size of the remanufactured retired new energy vehicle drive motor can match the installation interface and space requirements of the device to be combined, the mechanical interface adaptation can ensure the consistency of mechanical interfaces such as shaft ends and flanges, or realize interface conversion through adapters, the heat dissipation method adaptation such as air cooling and water cooling can ensure that the heat dissipation performance of the remanufactured retired new energy vehicle drive motor meets the use requirements, and the control interface adaptation can ensure that the control interface of the remanufactured retired new energy vehicle drive motor is compatible with the control interface of the device to be combined. At this time, the electrical interface, communication protocol, etc. need to be adjusted, and the drive characteristics adaptation such as voltage, current, torque and speed control can ensure that the remanufactured retired new energy vehicle drive motor can operate normally in the device to be combined. PID (Proportion Integration Differentiation, proportional-integral-differential (PID) parameters, vector control algorithms and other control strategy adjustments can ensure that the remanufactured retired new energy vehicle drive motors achieve optimal performance. For another example, the performance indicators of the test include but are not limited to power, efficiency, temperature rise, vibration and noise. The benefit of this setting is that the remanufactured retired new energy vehicle drive motors can be verified and adjusted and optimized.

[0037] Furthermore, the life cycle monitoring subsystem 104 can collect operation data through the driving mechanism of the retired drive motor of the new energy vehicle, and monitor the operation status of the retired drive motor of the new energy vehicle according to the operation data, thereby realizing operations such as predictive maintenance and efficiency optimization. Furthermore, since the power supply strategy of new energy vehicles cannot adapt to industrial 380V three-phase AC power, such as Figure 2 As shown, the embodiment of the present application can rectify and double the voltage of industrial 380V three-phase AC power to match the DC bus power supply voltage of the controller of the original retired drive motor of the new energy vehicle by adding a current converter. Figure 2The box part represents the controller of the original retired new energy vehicle drive motor, and M represents the body of the retired new energy vehicle drive motor. That is to say, the driving mechanism of the remanufactured retired new energy vehicle drive motor includes but is not limited to a current converter, an inverter and a drive processor, etc. The first end of the current converter is connected to industrial three-phase alternating current, the second end of the current converter is connected to the first end of the inverter, the second end of the inverter is connected to the body of the retired new energy vehicle drive motor, the third end of the inverter is connected to the first end of the drive processor, and the second end of the drive processor is connected to the third end of the current converter. The current converter can convert industrial three-phase alternating current into direct current, and the drive processor can collect operating data through the inverter and adjust the working parameters of the current converter according to the operating data to ensure that the entire system can operate in a coordinated, efficient and stable manner.

[0038] For example, ① the target device in the embodiment of the present application may be a conveyor 20. Please refer to Figure 3 , the transmission machine 20 includes a transmission body 201, a transmission shaft 202 and a retired new energy vehicle drive motor 203, wherein the retired new energy vehicle drive motor 203 is coaxially installed with the transmission shaft 202, so as to achieve a high dynamic response capability following the load change. For example, the transmission body 201 may include any one of a fan body, a water pump body and a compressor body. For another example, the transmission machine 20 may also include a retired radiator 204 and a bracket 205 for supporting the retired new energy vehicle drive motor 203, and the retired radiator 204 is provided on the bracket 205 near the retired new energy vehicle drive motor 203. The advantage of such a setting is that it can make full use of components such as new energy vehicle drive motors, controllers and radiators, and the remanufacturing cost is only half of that of purchasing a new machine, but the system efficiency can be increased by 15% to 30%, and the speed regulation range of 1000rpm / min to 12000rpm / min is met. For example, a retired new energy vehicle drive motor with a rotation speed of 30,000 can be used in stages for ultra-high speed fan load scenarios such as air suspension or magnetic suspension blowers.

[0039] ② In the embodiment of the present application, the target device may be a generator 30. Please refer to Figure 4 and Figure 5 The generator 30 includes a diesel engine 301, a flange connector 302, and a retired new energy vehicle drive motor 303, wherein one end of the flange connector 302 is connected to the output shaft of the retired new energy vehicle drive motor 303, and the other end of the flange connector 302 is connected to the flywheel side of the output shaft of the diesel engine 301. For example, the water cooling inlet of the retired new energy vehicle drive motor 303 is connected to the cooling water tank input port of the diesel engine 301, and the water cooling outlet of the retired new energy vehicle drive motor 303 is connected to the cooling water tank output port of the diesel engine 301, thereby sharing the cooling system, saving manufacturing costs, and facilitating unified maintenance.

[0040] Furthermore, for example, the generator 30 may also include a base 304 for fixing the diesel engine 301 and a support base 305 for supporting the retired new energy vehicle drive motor 303. For another example, the generator 30 may also include a control mechanism 306, which includes but is not limited to a central processing unit and a load controller and a speed regulator respectively connected to the central processing unit, wherein the load controller can monitor the load parameters of the generator 30, and the central processing unit can send an adjustment instruction corresponding to the change amount to the speed regulator according to the change amount of the load parameter, and the speed regulator can respond to the adjustment instruction and adjust the current speed of the retired new energy vehicle drive motor 303 to ensure that its output voltage is within a stable range. Usually, the speed regulator is located in the drive mechanism of the retired new energy vehicle drive motor 303.

[0041] Furthermore, the control mechanism 306 also includes a position sensor connected to the central processing unit, which can monitor the current rotor position of the retired drive motor 303 of the new energy vehicle, and feed back the current rotor position to the central processing unit to control and adjust the magnetic field strength and direction of the rotor in the retired drive motor 303 of the new energy vehicle, and optimize the electromagnetic conversion efficiency. And, the control mechanism 306 also includes a current sensor connected to the central processing unit, which can monitor the output current of the retired drive motor 303 of the new energy vehicle, and feed back the output current to the central processing unit for fine-tuning, and optimize the operating state of the retired drive motor 303 of the new energy vehicle. In summary, the embodiment of the present application can ensure that the retired drive motor 303 of the new energy vehicle can respond quickly under different load changes through the above-mentioned adjustment of the central processing unit, and maintain stable voltage and frequency output, thereby improving the overall efficiency and stability of the system.
