[0037] The embodiments of the present invention are described in detail below. Implementations of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and are not to be construed as limiting the present invention.

[0038] With the continuous development of new energy vehicles, users' functional demands for new energy vehicles are also increasing. At present, the domestic general way to meet the new functional demands is to increase the number of electronic control modules in the vehicle, which has led to an increase in the number and types of electronic control modules on the vehicle. The space occupied by them has also increased, and the number of wiring harnesses between each electronic control module has also increased. Therefore, in order to meet the increasingly diverse functional requirements, the components of multiple electronic control modules are often integrated into one, eliminating the connection harnesses between components and the fixing brackets of individual components. In related technologies, the safety and reliability of the use of electronic control modules needs to be improved.

[0039] 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 integrated high-voltage power modules 110, which can be used for energy conversion; the control module 30 includes a plurality of integrated low-voltage control modules 310, which can be used to control the operation of the high-voltage power modules 110.

[0040] Specifically, the integrated controller 100 can be set in the power battery pack. If the component is a high-voltage power component, it can be integrated into the drive module 10; if the component is a low-voltage control component, it can be integrated into the control module 30, so as to realize the differentiated 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 electrical energy, magnetic energy, kinetic energy, etc., and often generates a large amount of heat energy. When integrated, a large gap needs to be set between each other, while the low-voltage control component does not need to reserve a large gap. Therefore, integrating the low-voltage control component 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 set together, the low-voltage control component may 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 faults. 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.

[0041] In this way, by integrating the high-power components that realize the high-voltage function into the driving module 10 and integrating the low-voltage control components into the control module 30, the high-voltage power module 110 and the low-voltage control module 310 that will generate large amounts of heat energy are separately integrated, thereby reducing the impact 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 safety and reliability of the integrated controller 100.

[0042] 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. The first core 3101 is used to control the charging module to control the AC charging and discharging port 300 to charge and discharge the battery.

[0043] Specifically, under the control of the first core 3101 of the control chip 31, the charging module can be used to control the AC charging and discharging port 300 to charge and discharge the battery. 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 into a DC voltage to convert it into the set charging voltage to charge the battery.

[0044] In this way, under the control of the first core 3101 , the charging module can control the AC charging and discharging port 300 to charge and discharge the battery, thereby realizing charging and discharging of the battery.

[0045] Please refer to Figure 2. In some embodiments, the charging module includes an on-board charging module 11 and a DC conversion module 13. The on-board 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-board charging module 11 and the battery; the first core 3101 is used to control the on-board charging module 11 and the DC conversion module 13 to control the AC charging and discharging port 300 to charge and discharge the battery.

[0046] Specifically, the battery includes a power battery 501 and a low-voltage battery 503. The power battery 501 and the integrated controller 100 are arranged in a power battery pack. Charging and discharging the power battery 501 is equivalent to charging and discharging the battery cells. The on-board charging module 11 is connected to the AC charging and discharging port 300 and the battery cells. The DC-DC conversion module 13 is connected to the low-voltage battery 503. The DC-DC is also connected to the connection between the on-board 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 operation of the on-board charging module 11 and the DC-DC, so as to control the AC charging and discharging port 300 to charge the battery cells and / or the low-voltage battery 503, or to control the battery cells and / or the low-voltage battery 503 to discharge to the outside through the AC charging and discharging port 300. In addition, the first core 3101 is used to control the onboard charging module 11 and the DC-DC circuit to control the low-voltage battery 503 to charge the power battery 501. The first core 3101 is also used to control the DC-DC circuit to pre-charge the power battery 501, and then control the onboard charging module 11 to control the AC charging and discharging port 300 to charge the pre-charged power battery 501. This eliminates the need for separate control components for each function; the first core 3101 can be reused to implement the above functions, reducing the number of control components and the space occupied by the control components.

[0047] In this way, the first core 3101 of the control chip 31 can control the operation of the on-board charging module 11 and the DC-DC to control the AC charging and discharging port 300 to charge and discharge the battery cells and / or the low-voltage battery 503, thereby realizing the control of the charging of the battery cells and / or the low-voltage battery 503, and there is no need to set up separate control components for charging and discharging, thereby reducing the number of control components and realizing functional integration.

[0048] Please refer to Figures 2 and 3. In some embodiments, the battery includes a power battery 501 and a low-voltage battery 503. The on-board charging module 11 includes an integrated first conversion circuit 111 and a second conversion circuit 113. The first core 3101 is used 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 used 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 also used 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.

[0049] Specifically, since the power battery 501 is charged at high voltage and the low-voltage battery 503 is charged at low voltage, a conversion circuit is provided to convert the voltage after AC charging and discharging to the required voltage to charge the battery. The first conversion circuit 111 is a PFC (Power Factor Correction) circuit, which is used to rectify and process the AC voltage of the AC charging and discharging port 300. The first conversion circuit 111 and the second conversion circuit 113 are integrated into the on-board 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 used to convert the AC voltage of the AC charging and discharging port 300 into a first DC voltage. The second conversion circuit 113 is used to convert the first DC voltage into a second DC voltage. The second DC voltage can charge the battery cells of the power battery 501. The DC-DC converter can convert the second DC voltage into a third DC voltage, which is lower than the second DC voltage. The third DC voltage can charge the low-voltage battery 503, thereby achieving voltage conversion and charging the power battery 501 and the low-voltage battery 503. In addition, the first DC circuit can be used to charge batteries in the vehicle that do not require high-voltage charging, and can also provide low-voltage power to the vehicle's power modules.

[0050] In this way, the first core 3101 outputs a pulse signal to control the first conversion circuit 111, the second conversion circuit 113 and the DC conversion circuit to perform voltage conversion, thereby enabling the first core 3101 to control battery charging.

In some embodiments, the first conversion circuit 111 includes a first bridge arm, a second bridge arm, a third bridge arm, a first capacitor, a first inductor, and a second inductor. Each bridge arm includes two switching tubes connected in series. The first bridge arm, the second bridge arm, the third bridge arm and the first capacitor are connected in parallel. The first end of the first inductor and the first end of the second inductor are commonly connected to the first port of the AC charge and discharge port 300.

That is, the midpoint of the switch tubes Q1 and Q2 is connected to the second end of the first inductor L1, the midpoint of the switch tubes Q3 and Q4 is connected to the second end of the second inductor L2, and the midpoint of the switch tubes Q5 and Q6 is connected to the second port of the AC charging and discharging port 300. The first core 3101 can output N groups of first pulse signals to control the opening or closing of the switches of the first conversion circuit 111, thereby converting the AC voltage of the DC charging and discharging port into a first DC voltage, that is, achieving conversion from AC voltage to DC voltage.

[0053] In this way, the first core 3101 outputs the first pulse signal to control the switching tube of the first conversion circuit 111 to convert the AC voltage into the first DC voltage, thereby realizing the conversion of the AC voltage of the AC charging and discharging port 300 into the first DC voltage.

[0054] 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 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 jointly connected to the two ends of the power battery 501. The first core 3101 can output N2 groups of second pulse signals to control the on and off of the switch tubes Q11, Q12, Q13 and Q14, thereby converting the first DC voltage obtained by the first conversion circuit 111 into a second DC voltage to charge the power battery 501, where N2 is an integer that can be adjusted according to demand.

[0056] In this way, the first core 3101 outputs a second pulse signal to control the on / off of the switch tube of the second conversion circuit 113, so as to convert the first DC voltage into a second DC voltage to obtain a voltage capable of charging the power battery 501, thereby charging the power battery 501.

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 through the first switch tube and the second switch tube and the diode, the fifth capacitor and the low-voltage battery 503; the first core 3101 is used to output a third pulse signal to control the switch tube of the DC conversion module 13 to open or close, so as to convert the second DC voltage into a third DC voltage.

[0058] Specifically, the eighth bridge arm includes a switch tube Q15 and a switch tube Q16 connected in series, and the ninth bridge arm includes a switch tube Q17 and a switch tube Q18 connected in series.

The source of the first switch tube Q01 and the source of the second switch tube Q02 are commonly connected to the diode D1 and the fifth capacitor C5, and are connected to the two ends of the low-voltage battery 503. The first core 3101 can output N3 groups of third pulse signals to control the on and off of the switch tubes Q15, Q16, Q17, Q18, the first switch tube Q01 and the second switch tube Q02, thereby converting the second DC voltage obtained by the second conversion circuit 113 into a third DC voltage to charge the low-voltage battery 503, where N3 is an integer that can be adjusted according to demand.

[0059] In this way, by outputting the third pulse signal through the first core 3101 to control the on and off of the switch tube of the DC conversion circuit, the second DC voltage can be converted into a third DC voltage to obtain a voltage that can charge the low-voltage battery 503, thereby realizing the charging of the low-voltage battery 503.
