[0002] In the prior art, the power module is one of the key semiconductor modules in the vehicle control system. The power module can be used for at least power conversion.

[0092] The power module, the electric control assembly and the vehicle provided by the application can be used in the field of power electronics, and the above is only an example and does not limit the application field of the power module, the electric control assembly and the vehicle provided by the application.

[0093] The terms "first", "second", "third", and "fourth" and the like in the specification and claims of the application and the description of the drawings are used to distinguish different objects, and are not used to limit a specific order.

[0094] In the embodiments of the application, the words such as "as an example" or "for example" are used to represent an example, illustration or description. Any embodiment or design scheme described as "as an example" or "for example" in the embodiments of the application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. In fact, the words such as "as an example" or "for example" are intended to present the relevant concept in a specific manner.

[0095] The terms used in the embodiment part of the application are only used to explain the specific embodiments of the application, and are not intended to limit the application.

[0096] New energy vehicles include electric drive assemblies (i.e., electric control assemblies mentioned below), so as to drive vehicles to travel by using electric energy. Taking a range-extended new energy vehicle as an example, its topology structure is as shown in the figure. Figure 1 The core component is a range extender, and the main function is to start the range extender when the power of the battery decreases to a certain extent, and the engine drives the generator to generate electricity. Part of the generated electricity can be used to supply the driving motor, and the other part can be used to charge the power battery.

[0097] The range-extended new energy vehicle has many advantages, including: in urban daily commuting, the range-extended electric vehicle can travel purely by electricity, zero emission, reduce tail gas pollution, and meet environmental protection requirements. At the same time, electric drive is more energy-saving than fuel drive, and reduces energy consumption and use cost.

[0098] The range-extended electric vehicle is equipped with an engine as a range extender, which can start power generation when the battery power is insufficient, providing continuous power for the vehicle, avoiding the problem of range anxiety caused by the limited range of pure electric vehicles, and making long-distance travel more convenient.

[0099] In addition, the range-extended new energy vehicle also has the following advantages in driving experience:

[0100] Pure electric drive: The extended-range topology is essentially a pure electric drive system. The vehicle's driving power is completely provided by the electric motor, and the engine does not directly participate in driving the vehicle, but plays the role of generating electricity. When the battery is low, start and convert fuel into electricity to power the electric motor or charge the battery. This pure electric drive makes the vehicle's power source single and pure, consistent with the driving method of pure electric vehicles, fundamentally ensuring the comfort of the driving experience.

[0101] Rapid power response: The characteristics of the electric motor determine that it can output maximum torque in an instant. On vehicles with extended-range topology, when the driver steps on the accelerator pedal, the electric motor can respond immediately and quickly output powerful power to achieve rapid starting and acceleration. This immediate power response is far superior to traditional gasoline vehicles, allowing drivers to feel a more direct and powerful pushback. Whether in frequent start-stop on urban roads or overtaking on highways, it can easily handle and bring a smooth driving experience.

[0102] No power interruption: During the driving process of the extended-range vehicle, since it is always driven by the electric motor, there is no power interruption problem during gear shifting of traditional gasoline vehicles. Whether driving at low speed or high speed, the power output remains continuous and smooth. Even during the process of starting the engine to generate electricity when the battery is low, the system can ensure that the power output of the electric motor is not affected through precise control strategies, and there will be no jerk or power interruption, thus providing drivers with a consistent and stable driving experience, improving driving comfort and safety.

[0103] However, in the prior art, the electric drive assembly of the extended-range new energy vehicle includes a generator, a drive motor, a generator controller, a drive motor controller, and other components. Among them, the generator controller and the drive motor controller are independent components, each having independent power blocks (such as converting between AC and DC through diode semiconductors, IGBT semiconductors, SiC semiconductors, etc.), current sensors, temperature sensors, motor rotor position sensors, and other sensors. The weight, volume, and cost are relatively high, and optimization is urgently needed.

[0104] Figure 2 The topology structure diagram of the existing driving module (also known as the driving power module) and the power generation module (also known as the power generation power module) of the extended-range new energy vehicle is shown. Referring to Figure 2 The driving module converts the DC power shown by the high-voltage battery into AC power for driving the drive motor to provide torque to rotate the wheels. The power generation module converts the AC power output by the generator into DC power for charging the high-voltage battery or providing power to the drive motor.

[0105] As mentioned before, with the development of new energy vehicle industry, market competition is increasingly fierce, and the pressure of cost control also increases. As an important part of the vehicle, how to optimize the electric control assembly from the aspects of cost, space utilization and performance has become a widely concerned problem.

[0106] In the electric control assembly, current sensors are needed to monitor the size and direction of the current of the power module. On the one hand, when abnormalities such as overcurrent occur, protection mechanisms can be triggered to prevent damage to the power module or other key components. On the other hand, based on the real-time current data provided by the autonomous current sensor, the working state of the power module can be adjusted to ensure the stability of the output.

[0107] In the traditional scheme, the current sensor usually exists as an independent component, including a magnetic core, a coil and other related parts. These components often need additional installation and fixing devices such as plastic packaging and screws to ensure their stability and safety. Not only does the complex assembly process lead to an increase in labor costs, but each independent current sensor and the materials needed for its installation, such as plastic packaging materials and fixing parts, also increase manufacturing costs.

[0108] On the other hand, in order to meet the needs of mechanical strength and electrical isolation, the overall structure of the independently existing current sensor is usually bulky and occupies a lot of space, which is a significant disadvantage in such a space-restricted environment as new energy vehicles.

[0109] In addition, each current sensor needs a relatively long connection cable to connect with the power module, which is easy to introduce electromagnetic interference and affect the stability and accuracy of the electric control assembly.

[0110] Figure 3 A terminal arrangement design diagram of a traditional power module is shown. As shown in Figure 3 In the prior art, the drive module and the power generation module use three independent half-bridge circuits, and the signal terminals are arranged along the edge of the substrate of each half-bridge circuit. Referring to Figure 3The gate signal terminal G1, the emitter signal terminal E1, and the collector signal terminal C1 are used to transmit a U-phase upper bridge drive signal of the drive module; the gate signal terminal G2, the emitter signal terminal E2, and the collector signal terminal C2 are used to transmit a U-phase lower bridge drive signal of the drive module; the gate signal terminal G3, the emitter signal terminal E3, and the collector signal terminal C3 are used to transmit a V-phase lower bridge drive signal of the drive module; the gate signal terminal G4, the emitter signal terminal E4, and the collector signal terminal C4 are used to transmit a V-phase lower bridge drive signal of the drive module; the gate signal terminal G5, the emitter signal terminal E5, and the collector signal terminal C5 are used to transmit a W-phase lower bridge drive signal of the drive module; the gate signal terminal G6, the emitter signal terminal E6, and the collector signal terminal C6 are used to transmit a W-phase lower bridge drive signal of the drive module; the temperature measurement signal terminal T1 and the temperature measurement signal terminal T2 are used to transmit a signal of a U-phase temperature measurement resistor; the temperature measurement signal terminal T3 and the temperature measurement signal terminal T4 are used to transmit a signal of a V-phase temperature measurement resistor; and the temperature measurement signal terminal T5 and the temperature measurement signal terminal T6 are used to transmit a signal of a W-phase temperature measurement resistor. At least 8 signal terminals are required in each half-bridge unit, and at least 24 signal terminals are required in the drive module or the power generation module. In order to ensure the electrical safety of devices in the control circuit matched with the power module, it is necessary to ensure that there is sufficient spacing between the signal terminals to reserve sufficient clearance for the installation of the devices of the control circuit. Therefore, on the one hand, the size of the independent conventional power module is large. On the other hand, the signal pin type thereof covers all and is distributed in a large spacing. When adapting the PCB design, in order to meet the limitation of the safety specification (for example, GB / T 16935.1-2008), more clearance needs to be considered, which leads to an increase in the design size of the adapted PCB. Thus, it is not conducive to the overall miniaturization requirement of the module.

[0111] In the prior art, one backing plate corresponds to each bridge arm in the power module, and a plurality of terminals are arranged in each bridge arm. Since there is a design spacing between the terminals, even if all the bridge arms in the prior art are integrated into the same backing plate, the area of the backing plate cannot be reduced, and the technical problem of reducing the area of the power module and miniaturizing the power module cannot be solved.

[0112] The inventor finds that, compared with the drive module, the working condition of the power generation module is more stable, which provides an optimization space for reducing the volume of the power module. In order to solve the above technical problem, the present application provides a power module. The power module includes a power generation module. The power generation power module includes at least two first bridge arms. The at least two first bridge arms are arranged on the same first backing plate, and the at least two first bridge arms share a first collector terminal (for example Figure 4 C7 in the middle).

[0113] Optionally, each of the at least two first bridge arms includes an upper bridge circuit and a lower bridge circuit. And, as Figure 4As shown, the at least two first bridge arms share the first collector terminal. Optionally, the first collector terminal is used for connecting with the collector of the upper bridge circuit. The power generation power module of the present application shares the first backplane by the at least two first bridge arms, and at the same time, the at least two first bridge arms share the first collector terminal through the shared first backplane, thereby reducing the backplane area required by the power generation power module. It should be noted that the backplane can also be referred to as a backplane structure. For example, the first backplane is also referred to as a first backplane structure. The upper bridge circuit / lower bridge circuit can also be referred to as an upper bridge arm circuit / lower bridge arm circuit.

[0114] According to the embodiments of the present application, the first collector terminal is electrically connected with the collector of the upper bridge circuit in the at least two first bridge arms. Optionally, the first collector terminal is electrically connected with the collector of the lower bridge circuit in the at least two first bridge arms.

[0115] According to the embodiments of the present application, the power generation power module further comprises a first terminal group and a second terminal group. The first terminal group comprises at least two pairs of first terminal pairs, and the at least two pairs of first terminal pairs are respectively used for electrically connecting with the emitter and the gate of the upper bridge circuit in the at least two first bridge arms. The first terminal pair comprises a first emitter terminal and a first gate terminal. The first emitter terminal is electrically connected with the emitter of the upper bridge circuit of the first bridge arm. The first gate terminal is electrically connected with the gate of the upper bridge circuit of the first bridge arm. The second terminal group comprises at least two pairs of second terminal pairs, and the at least two pairs of second terminal pairs are respectively used for electrically connecting with the emitter and the gate of the lower bridge circuit in the at least two first bridge arms.

[0116] Exemplarily, the second terminal group comprises a second emitter terminal and at least two second gate terminals. The emitter of the lower bridge circuit of the at least two first bridge arms sharing the same first backplane is electrically connected with the second emitter terminal, and the at least two second gate terminals are respectively electrically connected with the gate of the lower bridge circuit of the at least two first bridge arms. Exemplarily, the second terminal group comprises at least two emitter terminals, and the at least two emitter terminals are respectively electrically connected with the emitter of the lower bridge circuit of the first bridge arm. Exemplarily, the lower bridge circuit in the at least two first bridge arms shares the emitter terminal. According to the embodiments of the present application, as Figure 2 As shown, the collector of the lower bridge circuit in the same first bridge arm is electrically connected with the emitter of the upper bridge circuit of the first bridge arm, and therefore, the present application omits the collector terminal in the lower bridge circuit.

[0117] Exemplarily, as Figure 4 and Figure 5As shown, the power generation module includes three first bridge arms, and in the first terminal group, E8 and G8, E10 and G10, and E12 and G12 correspond to U, V, and W phases respectively. Among them, G8 transmits the upper bridge gate signal of the U phase, and E8 transmits the upper bridge emitter signal of the U phase; G10 transmits the upper bridge gate signal of the V phase, and E10 transmits the upper bridge emitter signal of the V phase; G12 transmits the upper bridge gate signal of the W phase, and E12 transmits the upper bridge emitter signal of the W phase. As an example, as shown in Figure 4 and Figure 5 As shown, E7 and G7, E9 and G9, and E11 and G11 are second terminal pairs in the second terminal group, which correspond to U, V, and W phases respectively. Among them, G7 transmits the lower bridge gate signal of the U phase, and E7 transmits the lower bridge emitter signal of the U phase; G9 transmits the lower bridge gate signal of the V phase, and E9 transmits the lower bridge emitter signal of the V phase; G11 transmits the lower bridge gate signal of the W phase, and E11 transmits the lower bridge emitter signal of the W phase. C7 is a first collector terminal, which is used to transmit the upper bridge collector signal of at least two first bridge arms. Optionally, the lower bridge circuits of at least two first bridge arms arranged on the same first backing plate in the power generation module share an emitter.

[0118] According to some optional embodiments, as shown in Figure 4 The power generation module provided by the application includes three first bridge arms, and at least two of the three first bridge arms are arranged on the same first backing plate. Optionally, the three first bridge arms are arranged on the same first backing plate, and the three first bridge arms share a first collector terminal. As an example, the three first bridge arms correspond to U, V, and W phases of alternating current respectively.

[0119] According to the embodiments of the application, the power generation module further includes a first thermistor. The first thermistor is used to measure the temperature of the first backing plate. The power generation module further includes a third terminal group, and the third terminal group includes at least two third terminals. As an example, as shown in Figure 4 The third terminal group includes two third terminals (T7, T8). The two third terminals (T7, T8) are respectively used to be electrically connected with two ends of the first thermistor, so as to be able to measure the temperature of the first backing plate. The at least two first bridge arms in the application share the first backing plate, and the first thermistor measures the temperature of the first backing plate, thereby reducing the number of temperature measurement terminals required by the power generation module.

[0120] Optionally, the at least two first bridge arms sharing the same first backing plate in the power generation module also share the third terminal group. As an example, when the power module includes the power generation module and the driving power module arranged side by side, the third terminal is arranged at one end of the first backing plate away from the driving power module. In this way, the accuracy of measuring the temperature of the first backing plate through the third terminal group can be improved. In this way, it is beneficial to detect the real temperature anomaly of the edge of the first backing plate and avoid heat accumulation in the first backing plate.

[0121] According to some optional embodiments, the upper bridge circuit and the lower bridge circuit in at least one first bridge arm of the power generation module are arranged approximately along the second direction, and the upper bridge circuit is offset in the first direction relative to the lower bridge circuit to reduce the parasitic inductance in the first bridge arm and provide conditions for the installation of the third terminal group. For example, the third terminal group is arranged on the side of the first liner opposite to the offset direction of the upper bridge circuit. For example Figure 4 As shown, the upper bridge circuit is offset to the left relative to the lower bridge circuit, and the third terminal group (T7, T8) is disposed on the right side of the first substrate. For another example, the upper bridge circuit is offset to the right relative to the lower bridge circuit, and the third terminal group (T7, T8) is disposed on the left side of the first substrate.

[0122] Optionally, the upper bridge circuit and the lower bridge circuit in at least one first bridge arm of the power generation module are arranged approximately along the second direction, and the upper bridge circuit is offset in the first direction compared to the lower bridge circuit to reduce thermal coupling between the upper bridge circuit and the lower bridge circuit.

[0123] According to some optional embodiments, Figure 4 、 Figure 5 and Figure 6 As shown, the power module also includes a DC port. All lower bridge circuits in the first bridge arm of the power module are symmetrically distributed about the central axis of the DC port's lead-out direction. This facilitates an offset in the first direction between the upper bridge circuit and the lower bridge circuit, reducing parasitic inductance in the first bridge arm and facilitating installation of the third terminal assembly. Exemplarily, the DC port is configured as a laminated busbar structure.

[0124] In the embodiment of the present application, at least two first bridge arms share a first liner, and by also sharing a first collector terminal, the liner area required for the power generation module is reduced. This provides a foundation for the integration of the power generation module and the drive power module, facilitating the overall miniaturization of the power module.

[0125] In order to solve the above-mentioned technical problems, the present application provides a power module, including multiple integrated driving power modules and power generation modules. In an embodiment of the present application, the power module includes a PCB board adapted to the driving power module and the power generation module, electronic devices are provided on the PCB board, through holes are provided between the electronic devices, and the terminals on the driving power module and the power generation module correspond to the positions of the through holes one by one and pass through the through holes. Therefore, by optimizing the layout of the terminals, the terminals have a more compact layout structure, which can further reduce the size of the corresponding PCB board. The power module provided by the present application adopts a two-in-one design of a driving module and a power generation module, so that the total area of ​​the PCB is compressed, which can reduce the area of ​​the PCB by more than 40%.
