[0047] The vehicle controller 1 according to an embodiment of the present invention will be described below with reference to the drawings.
[0048] As Figures 1-8 shown, the vehicle controller 1 according to an embodiment of the present invention includes a box body 100, a control board 200, a drive board 300, and a switch 400.
[0049] The control board 200 is installed inside the box body 100. The control board 200 includes a communication module, a vehicle control module, a charging control module, and a motor control module. The vehicle control module controls the operation of the vehicle according to the signals of the communication module. The drive board 300 is installed inside the box body 100. The control board 200 is connected to the drive board 300. The motor control module controls the vehicle motor through the drive board 300. The switch 400 is installed inside the box body 100 and is connected to the control board 200. The switch 400 has an input end and an output end. The charging control module controls the on / off of the input end and the output end. The output end is connected to the energy storage component (not shown in the figure) of the vehicle, and the input end is connected to the charging line 430 of the energy storage component. The switch 400 can be a relay or a contactor, and the energy storage component can be a storage battery.
[0050] For example, the functions of the vehicle control module may include driving torque control, optimization control of braking energy, energy management of the whole vehicle, maintenance and management of the vehicle network, diagnosis and handling of faults, and vehicle status monitoring, etc. The vehicle control module is connected to the vehicle's central control. The charging control module can protect the energy storage component and avoid overcharging the energy storage component while controlling the charging of the energy storage component.
[0051] According to the vehicle controller 1 of an embodiment of the present invention, the control board 200 is installed inside the box body 100. The control board 200 includes a communication module, a vehicle control module, a charging control module, and a motor control module. The vehicle control module controls the operation of the vehicle according to the signals of the communication module. The communication module is used to receive and send various operation signals of the vehicle. The communication module can be connected to the vehicle control module, the charging control module, and the motor control module. The vehicle control module is also respectively connected to the charging control module and the motor control module.
[0052] It can be understood that the communication module, the vehicle control module, the charging control module, and the motor control module in the embodiment of the present invention are all integrated on the same control board 200, that is, the control board 200 has the functions of vehicle control, charging control, and motor control at the same time. The control board 200 has a high integration level and more functions. Therefore, only by disassembling and assembling the control board 200 can the disassembly and assembly of the communication module, the vehicle control module, the charging control module, and the motor control module be completed. Compared with the communication module, the vehicle control module, the charging control module, and the motor control module that are separately arranged in the related art, the disassembly and assembly efficiency of the vehicle controller 1 in the embodiment of the present invention is higher, and there is no need to additionally arrange conductive parts such as wires or busbars between the above four control modules, reducing the number of parts and further simplifying the disassembly and assembly steps. Moreover, only one box body 100 can be used to install the above four modules at the same time. The number of box bodies 100 is reduced and the overall volume is reduced, which can realize the integrated setting of the box body 100 and is beneficial to the miniaturization of the vehicle controller 1.
[0053] Moreover, when the energy storage component supplies power to the control board 200, it can supply power to the four modules of the communication module, the vehicle control module, the charging control module, and the motor control module at the same time, without separately supplying power to the four modules, which is beneficial to reducing the number of parts and saving costs.
[0054] In addition, the drive board 300 is installed inside the box body 100. The control board 200 is connected to the drive board 300. The motor control module controls the vehicle motor through the drive board 300. For example, the control board 200 sends a control signal to the drive board 300, and the drive board 300 can drive the vehicle motor to run at different speeds. And the control board 200 can receive the signals fed back when the vehicle motor runs through the communication module to timely adjust the speed control of the vehicle motor. Among them, the control board 200 and the drive board 300 can be connected through conductive parts such as wires or connectors.
[0055] The control board 200 and the drive board 300 can be respectively connected and fixed to the box body 100 to make the electrical connection more reliable. At the same time, the conductive parts used to connect the control board 200 and the drive board 300 can be hidden inside the box body 100, with higher electrical connection safety. Moreover, the box body 100 can provide an electromagnetic shielding effect for the control board 200, so that the signals received and transmitted by the control board 200 have small fluctuations.
[0056] In addition, the on-off part 400 is installed inside the box body 100 and connected to the control board 200. The on-off part 400 has an input end and an output end. The charging control module controls the on-off of the input end and the output end. The output end is connected to the energy storage part of the vehicle, and the input end is connected to the charging line 430 of the energy storage part. Among them, the energy storage part of the vehicle can be a storage battery, and the energy storage part can supply electric energy to the vehicle controller 1, so as to realize the normal operation of the vehicle controller 1.
[0057] Specifically, when the energy storage part is charging, the input end and the output end are connected; when the energy storage part stops charging, the input end and the output end are disconnected. The communication module can receive the charging situation of the energy storage part. The vehicle control module controls the on-off of the input end and the output end through the charging control module. For example, when the energy storage part is fully charged or a charging fault occurs, the charging control module can disconnect the input end and the output end, thereby interrupting the charging of the energy storage part and protecting the energy storage part, with high charging safety.
[0058] Among them, the charging line 430 can be connected to the charging pile outside the vehicle through the on-vehicle charger.
[0059] In this way, the vehicle controller 1 according to the embodiment of the present invention can integrate the vehicle control function, the charging control function and the motor control function on the same control board 200, and has the advantages of high integration, few parts, good shielding effect and reliable electrical connection.
[0060] According to some specific embodiments of the present invention, as Figure 1 and Figure 2 shown, the communication module includes a signal plug-in part 210. The signal plug-in part 210 exposes from the box body 100. The signal plug-in part 210 has a plug-in area 211 for signal transmission. Specifically, the plug-in area 211 exposes from the box body 100 to facilitate signal transmission between the control board 200 and other structures of the vehicle.
[0061] In addition, a signal shielding cover 220 is installed on the control board 200. The signal shielding cover 220 can accelerate the attenuation of electronic noise. The signal shielding cover 200 wraps the part of the signal plug-in part 210 except the plug-in area 211. In this way, it can avoid the noise generated by other electronic devices from interfering with the signals received and sent by the signal plug-in part 210, reduce the signal fluctuation of the signal plug-in part 210, so that the control board 200 can effectively control the vehicle and improve the driving safety.
[0062] According to some specific embodiments of the present invention, as Figure 2 shown, the input end is connected with a positive charging row 411 and a negative charging row 412. The positive pole of the charging wire 430 is connected with the positive charging row 411, the negative pole of the charging wire 430 is connected with the negative charging row 412, and the charging wire 430 passes through the box body 100. The output end is connected with a positive DC row 421 and a negative DC row 422. The box body 100 is provided with a DC connector 110, and the DC connector 110 protrudes from the box body 100. Both the positive DC row 421 and the negative DC row 422 are connected with one end of the DC connector 110, and the other end of the DC connector 110 is connected with the energy storage component.
[0063] For example, the DC connector 110 can be fixedly connected with the box body 100. One end of the DC connector 110 protruding from the box body 100 is connected with the energy storage component. The energy storage component can be connected with the DC connector 110 in a pluggable manner. Since the energy storage component is arranged outside the box body 100, by setting the DC connector 110, the electrical connection between the energy storage component and the vehicle controller 1 is more stable. And, the positive charging row 411 and the negative charging row 412 can be integrally formed and non-electrically connected. For example, the positive charging row 411 and the negative charging row 412 are injection-molded. The positive DC row 421 and the negative DC row 422 can be integrally formed and non-electrically connected. For example, the positive DC row 421 and the negative DC row 422 are injection-molded. The positive charging row 411, the negative charging row 412, the positive DC row 421 and the negative DC row 422 can all be made of metal copper.
[0064] By setting the positive charging row 411, the negative charging row 412, the positive DC row 421 and the negative DC row 422, the electrical connection between the charging wire 430 and the energy storage component can be realized, and since the rigidity of the above conductive rows is greater than that of the wire, the stability of the relative positions of the box body 100 and the above four conductive rows can be improved, thereby improving the structural and electrical connection reliability of the vehicle controller 1.
[0065] Furthermore, as Figure 2 shown, the box body 100 is provided with a first magnetic ring 120. Both the positive DC row 421 and the negative DC row 422 pass through the first magnetic ring 120, that is, the current flowing through the positive DC row 421 and the negative DC row 422 needs to pass through the first magnetic ring 120. By adding the first magnetic ring 120, the noise generated by the current flowing through the positive DC row 421 and the negative DC row 422 can be effectively suppressed to optimize the electromagnetic compatibility.
[0066] According to some specific embodiments of the present invention, as Figure 2As shown, the vehicle controller 1 further includes a DC connector 110, a capacitor 500, and an IGBT module 530 (Insulated Gate Bipolar Transistor).
[0067] The DC connector 110 is installed on the box body 100 and connected to the energy storage component. The capacitor 500 is installed on the box body 100 and has a capacitor input terminal 510 and a capacitor output terminal. The DC connector 110 is connected to the capacitor input terminal 510. The energy storage component can input electric energy into the capacitor 500 through the DC connector 110. By setting the capacitor 500, the direct current flowing to the IGBT module 530 can have smaller fluctuations, avoiding damage to the IGBT module 530 due to too large current fluctuations and improving the service life of the IGBT module 530.
[0068] The IGBT module 530 is installed on the box body 100 and has a DC input terminal, an AC output terminal, and a signal output terminal. The DC input terminal is connected to the capacitor output terminal. The capacitor 500 can output direct current to the IGBT module 530 through the capacitor output terminal and the DC input terminal. The signal output terminal is connected to the drive board 300. The IGBT module 530 can transmit electrical signals with the drive board 300 through the signal output terminal. The AC output terminal is connected to the three-phase input terminal of the vehicle's motor. The IGBT module 530 can invert direct current into alternating current and output three-phase alternating current to the vehicle's motor through the AC output terminal, thereby driving the motor to operate and the vehicle to run normally.
[0069] Furthermore, as Figure 2 and Figure 3 shown, the vehicle controller 1 further includes an electromagnetic shielding plate 600. The electromagnetic shielding plate 600 is installed on the box body 100. The control board 200 is located on the side of the electromagnetic shielding plate 600 facing away from the box body 100, and the drive board 300, the capacitor 500, and the IGBT module 530 are located on the side of the electromagnetic shielding plate 600 facing the box body 100.
[0070] In other words, the electromagnetic shielding plate 600 can separate the control board 200 from the drive board 300, the capacitor 500, and the IGBT module 530, that is, the drive board 300, the capacitor 500, and the IGBT module 530 are respectively located on opposite sides of the electromagnetic shielding plate 600 from the control board 200. The electromagnetic shielding plate 600 can be a metal part. The electromagnetic shielding plate 600 can accelerate the attenuation of electronic noise, avoid interference of the drive board 300, the capacitor 500, and the IGBT module 530 to the control board 200, and the signal transmission reliability of the control board 200 is high. Moreover, the electromagnetic shielding plate 600 can also be used to support the control board 200 and further fix the position of the control board 200 in the vehicle controller 1.
[0071] Optionally, as Figure 2As shown, the box body 100 is equipped with a three-phase transfer row 130 and a three-phase conductive member 140. The three-phase conductive member 140 is wrapped with an insulating member 141. The two ends of the three-phase transfer row 130 are respectively connected to the AC output end of the IGBT module 530 and one end of the three-phase conductive member 140, and the other end of the three-phase conductive member 140 is connected to the three-phase input end of the motor.
[0072] For example, the three-phase transfer row 130 and the three-phase conductive member 140 can be made of metal copper. The three-phase transfer row 130 and the three-phase conductive member 140 have high rigidity. Compared with wires, the relative position of the above conductive row and the box body 100 is more stable, and thus the electrical connection is more reliable. The insulating member 141 can be injection-molded on the three-phase conductive member 140. Both ends of the three-phase conductive member 140 are exposed from the insulating member 141, which is convenient for realizing electrical connection. At the same time, the insulating member 141 can cover the main body part between the two ends of the three-phase conductive member 140, avoiding electrical conduction between the three-phase conductive member 140 and other components, and the safety of the electrical connection is higher.
[0073] In addition, the drive board 300 is equipped with a Hall element 310, and the three-phase transfer row 130 passes through the Hall element 310. The Hall element 310 can detect the current and voltage input to the motor, and the drive board 300 can transmit the signal detected by the Hall element 310 to the control board 200, so that the control board 200 can timely adjust the control of the motor and improve the control accuracy.
[0074] According to some specific embodiments of the present invention, as Figure 4 shown, the control board 200 is connected with a resolver connector 230. The resolver connector 230 passes through the box body 100 and is connected to the motor of the vehicle. The resolver connector 230 is used to detect the angular displacement and angular velocity of the motor.
[0075] Among them, the resolver connector 230 can be fixed to the box body 100 to make the structure of the vehicle controller 1 stable. Through the resolver connector 230, the real-time working state of the motor can be detected and fed back to the control board 200. Thus, the control board 200 can timely adjust the angular displacement and angular velocity of the motor through the drive board 300 to make the vehicle run smoothly.
[0076] According to some specific embodiments of the present invention, as Figure 2 shown, the vehicle controller 1 further includes a DC connector 110, a power supply board 700, an AC output connector 800, and a DC output connector 814.
[0077] The DC connector 110 is installed on the box 100 and connected to the energy storage component. The power supply board 700 is connected with a positive power supply line, a negative power supply line, a power signal line 780, an AC transfer terminal, and a DC transfer terminal. Both the positive power supply line and the negative power supply line are connected to the DC connector 110. The energy storage component inputs current to the power supply board 700 through the positive power supply line and the negative power supply line. The power signal line 780 is connected to the communication module to feedback the power state of the power supply board 700 to the control board 200 in real time.
[0078] Moreover, the AC output connector 800 is connected to the AC transfer terminal and installed on the box 100. The AC output connector 800 protrudes from the box 100, facilitating the connection between the AC output connector 800 and electrical devices outside the box 100. The power supply board 700 can convert the direct current input by the energy storage component into alternating current, and then supply power to the electronic devices in the vehicle that require alternating current through the AC output connector 800. At the same time, the DC output connector 814 is installed on the box 100 and connected to a DC transfer row 811 and a DC filter board 813. The DC filter board 813 can suppress electronic noise, making the direct current output by the DC output connector 814 more stable.
[0079] Specifically, the DC filter board 813 is connected to the DC transfer terminal. The current flows from the DC filter board 813 to the DC transfer row 811 and then is output through the DC output connector 814. That is, the DC output connector 814 is indirectly connected to other parts of the power supply board 700 through the DC transfer row 811 and the DC filter board 813. The DC output connector 814 protrudes from the box, facilitating the connection between the DC output connector 814 and electronic devices outside the box 100.
[0080] Among them, the power supply board 700 can convert the direct current input by the energy storage component into direct current with different powers, that is, the power of the direct current input to the power supply board 700 is different from the power of the direct current output by the power supply board 700, and then supply power to the electronic devices in the vehicle that require this power of direct current through the DC output connector 814.
[0081] According to some specific embodiments of the present invention, as Figure 3 shown, the power supply board 700 is disposed adjacent to one side in the thickness direction of the box 100, and the control board 200 and the drive board 300 are disposed adjacent to the other side in the thickness direction of the box 100.
[0082] Specifically, spaces capable of accommodating components can be constructed on opposite sides of the box 100 in its thickness direction. In this way, while the box 100 can accommodate the power supply board 700, the control board 200, and the drive board 300, the distance between the power supply board 700 and the control board 200 and the drive board 300 can be increased, thereby reducing the electromagnetic interference of the power supply board 700 on the control board 200 and the drive board 300 and improving electromagnetic compatibility.
[0083] According to some specific embodiments of the present invention, as Figures 1-3 shown, the vehicle controller 1 further includes a first cover plate 900 and a second cover plate 910.
[0084] The first cover plate 900 is installed on one side in the thickness direction of the box body 100 and covers the power supply board 700, and the second cover plate 910 is located on the other side in the thickness direction of the box body 100 and covers the control board 200 and the drive board 300.
[0085] By providing the first cover plate 900 and the second cover plate 910, it is convenient to disassemble and assemble the power supply board 700, the control board 200 and the drive board 300. Moreover, the first cover plate 900 covers the power supply board 700, and the second cover plate 910 covers the control board 200 and the drive board 300, which can not only prevent the power supply board 700, the control board 200 and the drive board 300 from detaching from the box body 100, but also protect the power supply board 700, the control board 200 and the drive board 300 from being damaged by collision, and avoid the power supply board 700, the control board 200 and the drive board 300 from interfering with the electronic devices outside the vehicle controller 1.
[0086] According to some specific embodiments of the present invention, as Figure 8 shown, a first electrical protection component 710 is connected to the positive power supply line of the power supply board 700, and the first electrical protection component 710 is connected to the DC plug 110.
[0087] For example, the first electrical protection component 710 can be a fuse. In this way, when the current or voltage transmitted by the positive power supply line is too large, the first electrical protection component 710 can melt itself to break the circuit, thereby cutting off the transmission of current to the power supply board 700, protecting the power supply board 700, and avoiding damage to the power supply board 700 due to excessive current.
[0088] According to some specific embodiments of the present invention, as Figure 5 shown, a second magnetic ring 812 is wound around the outer peripheral surface of the DC transfer row 811. The second magnetic ring 812 can be sleeved on the DC transfer row 811. By adding the second magnetic ring 812, the noise generated by the current flowing through the DC transfer row 811 can be effectively suppressed, so that the direct current output by the DC output plug 814 has smaller fluctuations.
[0089] According to some specific embodiments of the present invention, as Figure 6 and Figure 7 shown, an AC shielding cavity 154, a power line shielding cavity 151, a power signal line shielding cavity 152 and a DC output shielding cavity 153 are provided on the side of the box body 100 facing the power supply board 700.
[0090] The wires of the AC output connector 800 are located in the AC shielding cavity 154. The AC shielding cavity 154 can accommodate the wires of the AC output connector 800, preventing the wires from physically interfering with other components and making the electrical connection more stable. The housing 100 is equipped with an AC shielding plate that covers the AC shielding cavity 154. That is, the AC shielding cavity 154 and the AC shielding plate jointly enclose the wires, which can not only prevent the wires from detaching from the AC shielding cavity 154 but also reduce the electronic noise generated by the wires outside the AC shielding cavity 154.
[0091] The positive power line and the negative power line are located in the power line shielding cavity 151, and the power signal line 780 is located in the signal line shielding cavity 152. The power line shielding cavity 151 can accommodate the positive power line and the negative power line, preventing the two power lines from physically interfering with other components and making the electrical connection more stable. The power line cover plate 700 covers the power line shielding cavity 151, and the signal line cover plate 156 covers the power signal line shielding cavity 152. This can not only prevent the two power lines from detaching from the power line shielding cavity 151 but also reduce the electronic noise generated by the power line shielding cavity 151 outside the power line shielding cavity 151.
[0092] The DC transfer row 811 and the DC filter board 813 are located in the DC output shielding cavity 153. The DC output shielding cavity 153 can accommodate the DC transfer row 811 and the DC filter board 813, preventing the DC transfer row 811 and the DC filter board 813 from physically interfering with other components and making the electrical connection more stable. The housing 100 is equipped with a DC shielding plate 171 that covers the DC output shielding cavity 153, thereby ensuring the shielding effect of the DC output shielding cavity 153 and preventing the DC transfer row 811 and the DC filter board 813 from detaching from the DC output shielding cavity 153.
[0093] By arranging multiple cavities at intervals, it is also possible to avoid mutual interference between the above-mentioned multiple electronic devices and further optimize electromagnetic compatibility.
[0094] According to some specific embodiments of the present invention, as Figure 5 shown, the power supply board 700 includes a board body 720, an AC inductor 730, a DC inductor 740, a transformer inductor 750, a transformer 760, and a MOS transistor 770.
[0095] The positive power supply line, negative power supply line, power signal line 780, AC transfer terminal, and DC transfer terminal are all provided on the board body 720. The AC inductor 730 and the DC inductor 740 are installed on both sides in the width direction of the board body 720. The AC inductor 730, DC inductor 740, and power signal line 780 are located at the same end of the board body 720 in the length direction of the board body 720. The transformer inductor 750 is installed on the board body 720 and is located between the AC inductor 730 and the DC inductor 740 in the width direction of the board body 720. The transformer 760 is installed on the board body 720 and is located at one end of the board body 720 away from the power signal line 780. The MOS transistor 770 is installed on the board body 720 and is located on both sides of the transformer 760 in the width direction of the board body 720.
[0096] Integrating the above-mentioned multiple power supply lines, multiple inductors, power signal line 780, and multiple MOS transistors 770 on the board body 720 means that one board body 720 can be used to install multiple electronic devices at the same time. The power supply board 700 has a high integration degree, and only by disassembling and assembling the board body 720 can the overall disassembly and assembly of the power supply board 700 be completed.
[0097] By setting the transformer 760 and the power signal line 780 at both ends of the board body 720, the distance between the transformer 760 and the power signal line 780 can be made far, and the electromagnetic interference of the transformer 760 on the power signal line 780 is small. Moreover, the layout method of the power supply board 700 can make the structure of the power supply board 700 more compact, which is beneficial to reducing the volume of the power supply board 700.
[0098] In this way, the power supply board 700 can output both direct current and alternating current, and the output direct current has a different voltage from the input direct current.
[0099] Furthermore, as Figure 6 shown, the side of the box body 100 facing the power supply board 700 is provided with a DC inductor shielding cavity 160, an AC inductor shielding cavity 161, a transformer inductor shielding cavity 162, and a MOS transistor shielding cavity 163.
[0100] The DC inductor 740 is located in the DC inductor shielding cavity 160, the AC inductor 730 is located in the AC inductor shielding cavity 161, the transformer inductor 750 is located in the transformer inductor shielding cavity 162, and the MOS transistor 770 is located in the MOS transistor shielding cavity 163. By setting multiple independent shielding cavities, the AC inductor 730, DC inductor 740, transformer inductor 750, and MOS transistor 770 can be located in different shielding cavities respectively. The electromagnetic interference between the AC inductor 730, DC inductor 740, transformer inductor 750, and MOS transistor 770 is small, and the electromagnetic interference to the outside is also smaller, which is beneficial to improving the overall electromagnetic compatibility.
[0101] Moreover, the board body 720 covers the DC inductor shielding cavity 160, the AC inductor shielding cavity 161, the transformer inductor shielding cavity 162, and the MOS transistor shielding cavity 163, which can prevent the above-mentioned transformer, multiple inductors, and multiple MOS transistors 770 from detaching from their respective shielding cavities, and has high position stability.
[0102] According to some specific embodiments of the present invention, as Figure 1 and Figure 2 shown, the box body 100 is equipped with a detachable maintenance board 180. The maintenance board 180 is equipped with a first electrical connector 181. The box body 100 is equipped with a second electrical connector 182 that conducts electricity in contact with the first electrical connector 181. The control board 200 detects the on / off state of the first electrical connector 181 and the second electrical connector 182 to control the on / off of the circuit of the energy storage component.
[0103] For example, the maintenance board 180 is detachably installed on the second cover plate 910. The first electrical connector 181 is installed on the side of the maintenance board 180 facing the box body 100. The second electrical connector 182 can be installed on the capacitor 500. In this way, when the maintenance board 180 is installed on the box body 100, the first electrical connector 181 and the second electrical connector 182 are electrically connected, and the vehicle controller 1 works normally. When the vehicle controller 1 needs to be repaired or detected, etc., first remove the maintenance board 180. At this time, the first electrical connector 181 and the second electrical connector 182 are separated. The control board 200 can detect that the first electrical connector 181 and the second electrical connector 182 are disconnected. An electromagnetic switch such as a relay or a contactor can be provided between the energy storage component and the DC plug connector 110. After the control board 200 detects that the first electrical connector 181 and the second electrical connector 182 are disconnected, it controls the relay or the contactor between the energy storage component and the DC plug connector 110 to disconnect, so as to cut off the power supply of the entire vehicle controller 1, which can protect the safety of maintenance personnel and facilitate the repair and detection of the vehicle controller 1.
[0104] According to some specific embodiments of the present invention, as Figure 1 shown, the vehicle controller 1 further includes a DC plug connector 110 and a power supply plug connector 920.
[0105] The DC plug connector 110 is installed on the box body 100 and is connected to the energy storage component. The power supply plug connector 920 is installed on the box body 100 and protrudes from the box body 100. The power supply plug connector 920 is connected with a positive heating wire and a negative heating wire, and both the positive heating wire and the negative heating wire are connected to the DC plug connector 110. The power supply plug connector 920 is connected to a heating component for heating the energy storage component.
[0106] Among them, after the power supply connector 920 is connected to the energy storage component and the heating component, the energy storage component can supply power to the heating component through the power supply connector 920 to make the heating component heat up, and the heating component can be located close to the energy storage component, thereby heating the energy storage component. It is understandable that in a low temperature environment, for example, in winter, the energy storage characteristics and power supply characteristics of the energy storage component may decline, thereby affecting the driving of the vehicle, and by adding a heating component, the temperature of the energy storage component can be ensured to be at a suitable temperature, thereby ensuring the performance of the energy storage component.
[0107] According to some specific embodiments of the present invention, Figure 8 As shown, the box is installed with a third magnetic ring 790, and both the positive heating wire and the negative heating wire pass through the third magnetic ring 190. This can suppress the noise generated by the current flowing through the positive heating wire and the negative heating wire, make the current output to the heating element more stable, and avoid damage to the heating element.
[0108] In addition, the positive electrode heating wire is connected to a second electrical protection component 921, and the second electrical protection component 921 is connected to the DC connector 110. The second electrical protection component 921 may be a fuse, so that when the current flowing to the positive electrode heating wire is too large, the second electrical protection component 921 itself may be melted to break the circuit and cut off the current transmission, thereby protecting the heating element and preventing the heating element from being damaged due to excessive current.
[0109] Optionally, the power supply connector 920 is connected to the compressor of the vehicle air conditioner. In this way, the energy storage component can be connected to the compressor through the power supply connector 920, that is, the energy storage component can simultaneously power the compressor and the heating component through the power supply connector 920, so that the compressor can work normally to adjust the temperature inside the vehicle and the heating component can be heated, thereby improving the utilization rate of the power supply connector 920 and reducing the number of parts of the vehicle controller 1.

[0111] The vehicle according to the embodiment of the present invention comprises the vehicle controller 1 according to the above-mentioned embodiment of the present invention, a power box 2, a motor, a transmission and an energy storage component.
[0112] The power box 2 is installed in the box body 100 of the vehicle controller 1, the motor and the transmission are transmission-connected and installed in the power box 2, and the motor is connected to the IGBT module 530. For example, the power box 2 is on the side of the power board 700 facing away from the box body 100. The power box 2 can be used to fix and shield the motor and the transmission to avoid damage to the motor and the transmission.
[0113] The motor is electrically connected to the drive board 300. The drive board 300 can drive the motor to operate. The energy storage component is connected to the output end of the switch component 400. The current of the external power supply flows through the switch component 400 and then to the energy storage component to charge the energy storage component. The switch component 400 is arranged between the energy storage component and the external power supply and can effectively control the on-off between the external power supply and the energy storage component, thereby protecting the energy storage component from overcharging.
