[0036] The following details the embodiments of the present invention. The embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0037] With the continuous development of new energy vehicles, the functional requirements of users for new energy vehicles are also increasing day by day. At present, in China, the way to meet the new functional requirements is generally to increase the in-vehicle electronic control modules, which makes the number and types of electronic control modules on the vehicle increase accordingly, and the space requirements they occupy are also increasing, and the wiring harnesses between the electronic control modules are also increasing. Therefore, in order to meet the increasingly diverse functional requirements, the components of multiple electronic control modules are often integrated into one to eliminate the connecting wiring harnesses between the components and the fixing brackets of individual components, etc. In the related art, the use safety and reliability of the electronic control modules need to be improved.

[0038] Please refer to Figure 1 , an embodiment of the present invention provides an integrated controller 100 for a vehicle 1000. The integrated controller 100 includes a drive module 10 and a control module 30. The drive module 10 includes a plurality of high-voltage power modules 110 integrally arranged, and the high-voltage power modules 110 can be used for energy conversion; the control module 30 includes a plurality of low-voltage control modules 310 integrally arranged, and the low-voltage control modules 310 can be used to control the operation of the high-voltage power modules 110.

[0039] Specifically, the integrated controller 100 can be disposed in the power battery pack. If the component is a high-voltage power component, it can be integrated in the drive module 10; if the component is a low-voltage control component, it can be integrated in the control module 30 to achieve the separate integration of the high-voltage power component and the low-voltage control component. The high-voltage power component can be used for energy conversion, such as voltage conversion, conversion between electric energy, magnetic energy, and kinetic energy, etc., and usually generates a large amount of heat. When integrated and arranged, a relatively large gap needs to be set between them. However, the low-voltage control component does not require a large gap to be reserved. Therefore, integrating the low-voltage control components together can reduce the occupied space. In addition, the accuracy requirements of the low-voltage control component are relatively high. If the low-voltage control component and the high-voltage power component are arranged together, it may cause the low-voltage control component to be affected by the heat energy and magnetic field generated by the high-voltage power component, resulting in a decrease in control accuracy or other failures. Therefore, integrating the low-voltage control component and the high-voltage power component separately can avoid the influence of the heat energy generated by the high-voltage power component on the low-voltage control component.

[0040] In this way, by integrating the high-power components that implement high-voltage functions in the drive module 10 and integrating the low-voltage control components in the control module 30, the high-voltage power module 110 and the low-voltage control module 310 that will generate a large amount of heat energy are separately integrated, reducing the influence of the heat energy of the high-voltage power module 110 on the low-voltage control module 310, and being able to improve the stability of the circuit and the electromagnetic compatibility level while reducing the occupied space, which is beneficial to improving the use safety and reliability of the integrated controller 100.

[0041] Please refer to Figure 2 , in some embodiments, the vehicle 1000 includes an integrated AC charging and discharging port 300 and a battery. The high-voltage power module 110 can be used for energy conversion. The high-voltage power module 110 includes a charging module; the low-voltage control module 310 includes a control chip 31. The control chip 31 includes a first core 3101, and the first core 3101 is used to control the charging module to control the charging and discharging of the battery by the AC charging and discharging port 300.

[0042] Specifically, under the control of the first core 3101 of the control chip 31, the charging module can be used to control the charging and discharging of the battery by the AC charging and discharging port 300. The charging module can rectify the AC voltage of the AC charging and discharging port 300 to convert it into a DC voltage to charge the battery; if the converted DC voltage does not meet the set charging voltage of the battery, the DC voltage can also be converted by DC voltage conversion to convert it into the set charging voltage to charge the battery.

[0043] In this way, under the control of the first core 3101, the charging module can control the charging and discharging of the battery by the AC charging and discharging port 300 to achieve the charging and discharging of the battery.

[0044] Please refer toFigure 2 , in some embodiments, the charging module includes an on-vehicle charging module 11 and a DC conversion module 13. The on-vehicle charging module 11 is connected to the AC charging and discharging port 300 and the battery, and the DC conversion module 13 is connected to the on-vehicle charging module 11 and the battery; the first core 3101 is used to control the on-vehicle charging module 11 and the DC conversion module 13 to control the AC charging and discharging port 300 to charge and discharge the battery.

[0045] Specifically, the battery includes the battery cells of the power battery 501 and the low-voltage storage battery 503. The power battery 501 and the integrated controller 100 are arranged in the power battery pack. Charging and discharging the power battery 501 means charging and discharging the battery cells. The on-vehicle charging module 11 is connected to the AC charging and discharging port 300 and the battery cells, and the DC conversion module 13 (DC-DC) is connected to the low-voltage storage battery 503. The DC-DC is also connected to the connection point between the on-vehicle charging module 11 and the battery cells. The control module 30 includes a control chip 31. The first core 3101 of the control chip 31 is used to control the on-vehicle charging module 11 and the DC-DC to work, so as to control the AC charging and discharging port 300 to charge the battery cells and / or the low-voltage storage battery 503, or control the battery cells and / or the low-voltage storage battery 503 to discharge to the outside through the AC charging and discharging port 300. In addition, the first core 3101 is also used to control the on-vehicle charging module 11 and the DC-DC to control the low-voltage storage battery 503 to charge the power battery 501; the first core 3101 is also used to control the DC-DC to pre-charge the power battery 501, and then control the on-vehicle charging module 11 to control the AC charging and discharging port 300 to charge the pre-charged power battery 501. Thus, there is no need to separately set control components for each function. Just by reusing the first core 3101, the above functions can be realized, reducing the number of control components, and thus reducing the space occupied by the control components.

[0046] In this way, through the first core 3101 of the control chip 31, the on-vehicle charging module 11 and the DC-DC can be controlled to work, so as to control the AC charging and discharging port 300 to charge and discharge the battery cells and / or the low-voltage storage battery 503, thereby realizing the control of charging the battery cells and / or the low-voltage storage battery 503, and there is no need to separately set control components for charging and discharging respectively, reducing the number of control components and realizing functional integration.

[0047] Please refer to Figure 2 and Figure 3, in some embodiments, the battery includes a power battery 501 and a low-voltage battery 503. The on-vehicle charging module 11 includes an integrated first conversion circuit 111 and a second conversion circuit 113. The first core 3101 is configured to output a first pulse signal to control the first conversion circuit 111 to convert the AC voltage of the AC charging and discharging port 300 into a first DC voltage; the first core 3101 is configured to output a second pulse signal to control the second conversion circuit 113 to convert the first DC voltage into a second DC voltage, and the second DC voltage can be used to charge the power battery 501; the first core 3101 is further configured to output a third pulse signal to control the DC conversion module 13 to convert the second DC voltage into a third DC voltage, and the third DC voltage can be used to charge the low-voltage battery 503.

[0048] Specifically, since the power battery 501 is charged at a high voltage and the low-voltage battery 503 is charged at a low voltage, a conversion circuit is provided to convert the voltage after AC charging and discharging into the required voltage to achieve battery charging. The first conversion circuit 111 is a PFC (Power Factor Correction) circuit for rectifying the AC voltage of the AC charging and discharging port 300 and processing the power quality. The first conversion circuit 111 and the second conversion circuit 113 are integrated into the on-vehicle charging module 11. The first core 3101 can output a pulse signal (PWM signal) to control the operation of the conversion circuit. When the first core 3101 outputs the first pulse signal, the first conversion circuit 111 is configured to convert the AC voltage of the AC charging and discharging port 300 into a first DC voltage, and the second conversion circuit 113 is configured to convert the first DC voltage into a second DC voltage, and the second DC voltage can charge the battery cells of the power battery 501; the DC-DC can convert the second DC voltage into a third DC voltage, the third DC voltage is less than the second DC voltage, and the third DC voltage can charge the low-voltage battery 503 to achieve voltage conversion, thereby achieving charging of the power battery 501 and the low-voltage battery 503. In addition, the first DC circuit can be used to charge the batteries of the vehicle that do not require high-voltage charging, and can also provide low-voltage power supply to the electrical modules of the vehicle.

[0049] In this way, by outputting a pulse signal by the first core 3101, the first conversion circuit 111, the second conversion circuit 113, and the DC conversion circuit can be controlled to perform voltage conversion, thereby achieving the control of the first core 3101 over battery charging.

[0050] Please refer to Figure 3, in some embodiments, the first conversion circuit 111 includes a first leg, a second leg, a third leg, a first capacitor, a first inductor, and a second inductor. Each leg contains two switching transistors connected in series. The first leg, the second leg, the third leg, and the first capacitor are connected in parallel with each other.

The midpoint of the first leg is connected to the first port of the AC charging and discharging port 300 through the first inductor. The midpoint of the second leg is connected to the first port of the AC charging and discharging port 300 through the second inductor. The midpoint of the third leg is connected to the second port of the AC charging and discharging port 300. The first core 3101 is configured to output a first pulse signal to control the switching transistors of the first conversion circuit 111 to turn on or off, so as to convert the AC voltage of the AC charging and discharging port 300 into a first DC voltage.

[0051] Specifically, the first leg includes switching transistors Q1 and Q2 connected in series, the second leg includes switching transistors Q3 and Q4 connected in series, and the third leg includes switching transistors Q5 and Q6 connected in series. The switching transistors Q1 and Q2, the switching transistors Q3 and Q4, the switching transistors Q5 and Q6, the switching transistors Q7 and Q, the switching transistors Q9 and Q10, and the first capacitor C1 are connected in parallel with each other. The first end of the first inductor L1 and the first section of the second inductor L2 are commonly connected to the first port of the AC charging and discharging port 300. The midpoint of the first leg is connected to the second end of the first inductor L1. The midpoint of the second leg is connected to the second end of the second inductor L2. The end point of the third leg is connected to the second port of the AC charging and discharging port 300, that is, the midpoint of the switching transistors Q1 and Q2 is connected to the second end of the first inductor L1, the midpoint of the switching transistors Q3 and Q4 is connected to the second end of the second inductor L2, and the midpoint of the switching transistors Q5 and Q6 is connected to the second port of the AC charging and discharging port 300. The first core 3101 is capable of outputting N groups of first pulse signals to control the switching transistors of the first conversion circuit 111 to turn on or off, so as to convert the AC voltage of the charging and discharging port into a first DC voltage, that is, to realize the conversion of the AC voltage to the DC voltage.

[0052] In this way, by outputting the first pulse signal by the first core 3101 to control the on-off of the switching transistors of the first conversion circuit 111, the AC voltage can be converted into a first DC voltage, and the AC voltage of the AC charging and discharging port 300 can be converted into a first DC voltage.

[0053] Please refer to Figure 3, in some embodiments, the second conversion circuit 113 includes a second capacitor, a third capacitor, a third inductor, a fourth inductor, a first transformer, a fourth bridge arm, a fifth bridge arm, a sixth bridge arm, and a seventh bridge arm. The fourth bridge arm, the fifth bridge arm, and the first capacitor of the first conversion circuit are connected in parallel with each other. The midpoint of the fourth bridge arm is connected to the first end of the first transformer through the second capacitor and the third inductor. The midpoint of the fifth bridge arm is connected to the second end of the first transformer. The sixth bridge arm and the seventh bridge arm are connected in parallel with each other and are commonly connected to both ends of the power battery 501. The midpoint of the sixth bridge arm is connected to the third end of the first transformer through the third capacitor and the fourth inductor. The midpoint of the seventh bridge arm is connected to the fourth end of the first transformer. The first core 3101 is configured to output a second pulse signal to control the on / off of the switching transistors of the second conversion circuit 113, so as to convert the first DC voltage into a second DC voltage.

[0054] Specifically, the first end of the first transformer T1 is connected to the midpoint of the fourth bridge arm through the second capacitor C2 and the third inductor, that is, the connection point between the switching transistors Q7 and Q8. The second end of the second transformer T2 is connected to the midpoint of the fifth bridge arm, that is, the connection point between the switching transistors Q9 and Q10.

The sixth bridge arm includes the series-connected switching transistors Q11 and Q12. The seventh bridge arm includes the series-connected switching transistors Q13 and Q14. The midpoint of the sixth bridge arm is connected to the third end of the first transformer T1 through the third capacitor C3 and the fourth inductor L4. The midpoint of the seventh bridge arm is connected to the fourth end of the first transformer T1. The sixth bridge arm and the seventh bridge arm are connected in parallel and are commonly connected to both ends of the power battery 501. The first core 3101 is capable of outputting N2 groups of second pulse signals to control the on / off of the switching transistors Q11, Q12, Q13, and Q14, so as to convert the first DC voltage obtained by the first conversion circuit 111 into a second DC voltage for charging the power battery 501, where N2 is an integer that can be adjusted according to requirements.

[0055] In this way, by outputting the second pulse signal by the first core 3101 to control the on / off of the switching transistors of the second conversion circuit 113, the first DC voltage can be converted into a second DC voltage to obtain a voltage capable of charging the power battery 501, thereby realizing the charging of the power battery 501.

[0056] Please refer to Figure 3, in some embodiments, the DC conversion module 13 includes an eighth bridge arm, a ninth bridge arm, a fourth capacitor, a fifth capacitor, a fifth inductor, a second transformer, a first switching tube, a second switching tube, and a diode. The eighth bridge arm and the ninth bridge arm are connected in parallel with each other.

The midpoint of the ninth bridge arm is connected to the second end of the second transformer. The third end and the fourth end of the transformer are respectively connected to the low-voltage battery 503 through the first switching tube, the second switching tube, the diode, the fifth capacitor; the first core 3101 is used to output a third pulse signal to control the switching tube of the DC conversion module 13 to be turned off or on, so as to convert the second DC voltage into a third DC voltage.

[0057] Specifically, the eighth bridge arm includes a series-connected switching tube Q15 and a switching tube Q16, and the ninth bridge arm includes a series-connected switching tube Q17 and a switching tube Q18. The eighth bridge arm and the ninth bridge arm are both connected in parallel with the seventh bridge arm.

The third end of the second transformer T2 is connected to the drain of the first switching tube Q01, and the fourth end of the second transformer T2 is connected to the drain of the second switching tube Q02. The sources of the first switching tube Q01 and the second switching tube Q02 are commonly connected to the diode D1 and the fifth capacitor C5, and are connected to both ends of the low-voltage battery 503.
