[0029] In the description of this disclosure, a "first feature" or a "second feature" may include one or more of the features.

[0030] In the description of this disclosure, "plurality" means two or more, and "several" means one or more.

[0031] Hereinafter, a vehicle controller 1 according to an embodiment of the present disclosure will be described with reference to the drawings.

[0032] As shown in FIGS. 1 to 8, a vehicle controller 1 according to an embodiment of the present disclosure includes a housing 100, a control board 200, a drive board 300, and an on / off element 400.

[0033] The control board 200 is mounted within the housing 100 and includes a communication module, a vehicle control module, a charge control module, and a motor control module. The vehicle control module controls the operation of the vehicle based on a signal from the communication module. The drive board 300 is mounted within the housing 100, and the control board 200 is connected to the drive board 300. The motor control module controls the vehicle motor via the drive board 300. The on / off element 400 is mounted within the housing 100 and connected to the control board 200. The on / off element 400 has an input terminal and an output terminal. The charge control module controls the on / off of the input terminal and the output terminal. The output terminal is connected to an energy storage element (not shown) of the vehicle, and the input terminal is connected to a charging line 430 of the energy storage element. The on / off element 400 may be a relay or a contactor, and the energy storage element may be a storage battery.

[0034] For example, the functions of the vehicle control module may include driving torque control, braking energy optimization control, vehicle energy management, vehicle network maintenance and management, fault diagnosis and handling, and vehicle status monitoring, and the vehicle control module is connected to the console of the vehicle. The charging control module can protect the energy storage element, control the charging of the energy storage element, and prevent overcharging of the energy storage element.

[0035] In the vehicle controller 1 according to the embodiment of the present disclosure, the control board 200 is mounted within the housing 100 and 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 based on signals from the communication module, the communication module transmits and receives various operating signals of the vehicle, and can be connected to the vehicle control module, the charging control module, and the motor control module, respectively, and the vehicle control module is further connected to the charging control module and the motor control module, respectively.

[0036] As can be seen, the communication module, vehicle control module, charging control module, and motor control module in the embodiment of the present disclosure are all integrated on the same control board 200. That is, the control board 200 simultaneously performs vehicle control functions, charging control functions, and motor control functions. Because the control board 200 is highly integrated and has more functions, the communication module, vehicle control module, charging control module, and motor control module can be installed and removed simply by installing and removing the control board 200. Compared with the related art, which uses separate communication modules, vehicle control module, charging control module, and motor control modules, the vehicle controller 1 according to the embodiment of the present disclosure has higher installation and removal efficiency and does not require the installation of conductive members such as wires or conductive pins for connection between the four control modules, thereby reducing the number of parts and further simplifying the installation and removal steps. Furthermore, the four modules can be installed simultaneously using only one housing 100, which reduces the number of housings 100 and the overall volume, enabling integrated installation of the housings 100 and contributing to the miniaturization of the vehicle controller 1.

[0037] In addition, when the energy storage element supplies power to the control board 200, it can simultaneously supply power to four modules, namely the communication module, the vehicle control module, the charging control module, and the motor control module, eliminating the need to supply power to each of the four modules individually, which helps reduce the number of components and lower costs.

[0038] Furthermore, the drive board 300 is mounted within the housing 100, the control board 200 is connected to the drive board 300, and the motor control module controls the vehicle motor via the drive board 300. For example, the control board 200 transmits a control signal to the drive board 300, which can drive the vehicle motor to operate at different rotational speeds. The control board 200 receives a feedback signal from the communication module when the vehicle motor operates, and can timely adjust the rotational speed control of the vehicle motor. The control board 200 and the drive board 300 may be connected by a conductive member such as a wire or a plug connector.

[0039] The control board 200 and the drive board 300 may be connected and fixed to the housing 100, respectively, to ensure a more reliable electrical connection. At the same time, the conductive members for connecting the control board 200 and the drive board 300 can be concealed within the housing 100, making the electrical connection safer, and the housing 100 can provide an electromagnetic shielding effect for the control board 200, thereby reducing fluctuations in the signals sent and received by the control board 200.

[0040] The on-off element 400 is mounted in the housing 100 and connected to the control board 200, and has an input terminal and an output terminal. The charging control module controls the on-off of the input terminal and the output terminal, and the output terminal is connected to the energy storage element of the vehicle, and the input terminal is connected to the charging line 430 of the energy storage member. The energy storage element of the vehicle may be a storage battery, and the energy storage element can send electrical energy to the vehicle controller 1 to ensure normal operation of the vehicle controller 1.

[0041] Specifically, when the energy storage element is being charged, the input terminal and the output terminal are turned on, and when charging of the energy storage element is stopped, the input terminal and the output terminal are turned off. The communication module can receive the charging status of the energy storage element, and the vehicle control module controls the on / off of the input terminal and the output terminal through the charging control module. For example, when the energy storage element is fully charged or there is a charging failure, the charging control module turns off the input terminal and the output terminal to stop charging of the energy storage element, thereby protecting the energy storage element and improving charging safety.

[0042] The charging line 430 may be connected to a charging station outside the vehicle via an on-board charger.

[0043] In this way, the vehicle controller 1 according to the embodiment of the present disclosure can integrate the vehicle control function, charging control function, and motor control function on the same control board 200, and has advantages such as high integration, a small number of components, excellent shielding effect, and reliable electrical connections.

[0044] According to some specific embodiments of the present disclosure, as shown in FIGS. 1 and 2 , the communication module includes a signal plug connector 210, which is exposed from the housing 100 and has a plug-in area 211 for signal transmission; specifically, the plug-in area 211 is exposed from the housing 100 and serves for signal transmission between the control board 200 and other structures of the vehicle.

[0045] In addition, a signal shielding cover 220 is attached to the control board 200, which can accelerate the attenuation of electronic noise and cover the parts of the signal plug connector 210 other than the plug-in area 211, thereby preventing noise from other electronic devices from interfering with the signals transmitted and received by the signal plug connector 210 and reducing fluctuations in signal transmission of the signal plug connector 210, allowing the control board 200 to effectively control the vehicle and improving driving safety.

[0046] 2 , a positive charging pin 411 and a negative charging pin 412 are connected to the input end, a positive pole of a charging line 430 is connected to the positive charging pin 411, a negative pole of the charging line 430 is connected to the negative charging pin 412, and the charging line 430 passes through the housing 100. A positive DC pin 421 and a negative DC pin 422 are connected to the output end, a DC plug connector 110 is attached to the housing 100, and the DC plug connector 110 is exposed from the housing 100, and the positive DC pin 421 and the negative DC pin 422 are both connected to one end of the DC plug connector 110, and the other end of the DC plug connector 110 is connected to an energy storage element.

[0047] For example, the DC plug connector 110 may be fixedly connected to the housing 100, and one end of the DC plug connector 110 exposed from the housing 100 may be connected to an energy storage element, and the energy storage element may be detachably connected to the DC plug connector 110. Since the energy storage element is installed outside the housing 100, installing the DC plug connector 110 provides a more stable electrical connection between the energy storage element and the vehicle controller 1. Furthermore, the positive charging pin 411 and the negative charging pin 412 may be integrally molded and non-electrically connected to each other. For example, the positive charging pin 411 and the negative charging pin 412 may be injection molded, and the positive DC pin 421 and the negative DC pin 422 may be integrally molded and non-electrically connected to each other. For example, the positive DC pin 421 and the negative DC pin 422 may be injection molded. The positive electrode charging pin 411, the negative electrode charging pin 412, the positive electrode DC pin 421, and the negative electrode DC pin 422 may all be made of metallic copper.

[0048] By installing the positive charging pin 411, the negative charging pin 412, the positive DC pin 421 and the negative DC pin 422, not only can the electrical connection between the charging line 430 and the energy storage element be realized, but also, since the rigidity of the above conductive pins is greater than the rigidity of the conductor, the stability of the relative position between the housing 100 and the above four conductive pins can be improved, thereby improving the structure and electrical connection reliability of the vehicle controller 1.

[0049] 2, a first magnetic ring 120 is attached to the housing 100, and both the positive DC pin 421 and the negative DC pin 422 pass through the first magnetic ring 120, i.e., the currents flowing through the positive DC pin 421 and the negative DC pin 422 must pass through the first magnetic ring 120. By adding the first magnetic ring 120, noise caused by the currents flowing through the positive DC pin 421 and the negative DC pin 422 can be effectively suppressed, thereby optimizing electromagnetic compatibility.

[0050] In some specific embodiments of the present disclosure, as shown in FIG. 2, the vehicle controller 1 further includes a DC plug connector 110, a capacitor 500, and an IGBT module 530 (Insulated Gate Bipolar Transistor).

[0051] The DC plug connector 110 is mounted on the housing 100 and connected to the energy storage element, the capacitor 500 is mounted on the housing 100 and has a capacitor input terminal 510 and a capacitor output terminal, the DC plug connector 110 is connected to the capacitor input terminal 510, and the energy storage element can input electrical energy into the capacitor 500 through the DC plug connector 110. By installing the capacitor 500, the fluctuation of the DC current flowing through the IGBT module 530 can be reduced, preventing the IGBT module 530 from being damaged due to excessive current fluctuation, and prolonging the service life of the IGBT module 530.

[0052] The IGBT module 530 is mounted in the housing 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, and the capacitor 500 outputs a DC current to the IGBT module 530 via the capacitor output terminal and the DC input terminal. The signal output terminal is connected to the drive board 300, and the IGBT module 530 can transmit electrical signals to each other via the signal output terminal and the drive board 300. The AC output terminal is connected to the three-phase input terminal of the vehicle motor, and the IGBT module 530 can inversely convert the DC current to AC current. The IGBT module 530 outputs a three-phase AC current to the vehicle motor via the AC output terminal, thereby driving the motor and ensuring normal operation of the vehicle.

[0053] In some embodiments of the present disclosure, as shown in Figures 2 and 3, the vehicle controller 1 further includes an electromagnetic shielding plate 600, which is attached to the housing 100, the control board 200 is located on the side of the electromagnetic shielding plate 600 facing away from the housing 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 towards the housing 100.

[0054] 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, i.e., the drive board 300, the capacitor 500, and the IGBT module 530 and the control board 200 are respectively installed on opposite sides of the electromagnetic shielding plate 600. The electromagnetic shielding plate 600 may be a metal fitting, which can accelerate the attenuation of electronic noise and prevent the drive board 300, the capacitor 500, and the IGBT module 530 from interfering with the control board 200, thereby improving the reliability of signal transmission of the control board 200. The electromagnetic shielding plate 600 can also support the control board 200 and fix the position of the control board 200 on the vehicle controller 1.

[0055] 2, the three-phase relay pin 130 and the three-phase conductive member 140 are preferably attached to the housing 100, and the three-phase conductive member 140 is enclosed in an insulating member 141. Both ends of the three-phase relay pin 130 are connected to the AC output terminal of the IGBT module 530 and one end of the three-phase conductive member 140, respectively, and the other end of the three-phase conductive member 140 is connected to the three-phase input terminal of the motor.

[0056] For example, the three-phase relay pin 130 and the three-phase conductive member 140 may be made of copper metal, which has high rigidity and makes the relative position of the conductive pin and the housing 100 more stable than that of a conductor, thereby ensuring a more reliable electrical connection. The insulating member 141 may be injection molded onto the three-phase conductive member 140, with both ends of the three-phase conductive member 140 exposed from the insulating member 141 to facilitate electrical connection. The insulating member 141 also encases the body portion between both ends of the three-phase conductive member 140, preventing electrical conduction between the three-phase conductive member 140 and other components, thereby ensuring a safer electrical connection.

[0057] In addition, a Hall element 310 is attached to the drive board 300, and the three-phase relay pin 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 transmits the signal detected by the Hall element 310 to the control board 200, allowing the control board 200 to adjust the control of the motor in a timely manner, thereby improving control accuracy.

[0058] In some specific embodiments of the present disclosure, as shown in FIG. 4, a resolver plug connector 230 is connected to the control board 200, and the resolver plug connector 230 penetrates the housing 100 and is connected to a motor of the vehicle, and the resolver plug connector 230 detects the angular displacement and angular velocity of the motor.

[0059] The resolver plug connector 230 may be fixed to the housing 100 to stabilize the structure of the vehicle controller 1, and the resolver plug connector 230 detects the real-time operating state of the motor and feeds back the operating state to the control board 200, so that the control board 200 can timely adjust the angular displacement and angular velocity of the motor via the drive board 300, thereby stabilizing the running of the vehicle.

[0060] According to some specific embodiments of the present disclosure, as shown in FIG. 2 , the vehicle controller 1 further includes a DC plug connector 110, a power supply board 700, an AC output plug connector 800, and a DC output plug connector 814.

[0061] The DC plug connector 110 is attached to the housing 100 and connected to the energy storage element, and the positive power line, negative power line, power signal line 780, AC relay terminal and DC relay terminal are connected to the power supply board 700, and the positive power line and negative power line are both connected to the DC plug connector 110, and the energy storage element inputs current to the power supply board 700 via the positive power line and negative power line, and the power signal line 780 is connected to the communication module, and the electrical energy status of the power supply board 700 is fed back to the control board 200 in real time.

[0062] Furthermore, the AC output plug connector 800 is connected to the AC relay terminal and attached to the housing 100, and is exposed from the housing 100 to facilitate connection between the AC output plug connector 800 and an electrical device outside the housing 100. The power supply board 700 converts the DC current input by the energy storage element into AC current, which can be supplied to an electronic device requiring AC current in the vehicle via the AC output plug connector 800. At the same time, the DC output plug connector 814 is attached to the housing 100, and is connected to the DC relay pins 811 and a DC filter plate 813. The DC filter plate 813 suppresses electronic noise to make the DC current output by the DC output plug connector 814 more stable.

[0063] Specifically, the DC filter plate 813 is connected to the DC relay terminal, and current flows from the DC filter plate 813 to the DC relay pin 811 and is output via the DC output plug connector 814; that is, the DC output plug connector 814 is indirectly connected to other parts of the power supply board 700 by the DC relay pin 811 and the DC filter plate 813, and the DC output plug connector 814 is exposed from the housing to facilitate connection between the DC output plug connector 814 and an electronic device outside the housing 100.

[0064] The power supply board 700 can convert the DC current input by the energy storage element into a DC current of a different power, i.e., the DC current power input to the power supply board 700 is different from the DC current power output by the power supply board 700, and further supplies the DC current to electrical devices in the vehicle that require the DC current through the DC output plug connector 814.

[0065] In some specific embodiments of the present disclosure, as shown in FIG. 3, the power supply board 700 is installed adjacent to one side of the housing 100 in the thickness direction, and the control board 200 and the drive board 300 are installed adjacent to the other side of the housing 100 in the thickness direction.

[0066] Specifically, the housing 100 can create spaces on opposite sides of its thickness that can accommodate components. In this way, the housing 100 can accommodate the power supply board 700, control board 200, and drive board 300, and the distance between the power supply board 700 and the control board 200 and drive board 300 can be increased, thereby reducing electromagnetic interference from the power supply board 700 to the control board 200 and drive board 300 and improving electromagnetic compatibility.

[0067] In some specific embodiments of the present disclosure, as shown in FIGS. 1 to 3, the vehicle controller 1 further includes a first cover plate 900 and a second cover plate 910.

[0068] The first cover plate 900 is attached to one side of the housing 100 in the thickness direction and covers the power supply board 700, and the second cover plate 910 is located on the other side of the housing 100 in the thickness direction and covers the control board 200 and the drive board 300.

[0069] By installing the first cover plate 900 and the second cover plate 910, the power supply board 700, the control board 200 and the drive board 300 can be easily attached and detached, and by having the first cover plate 900 cover the power supply board 700 and the second cover plate 910 cover the control board 200 and the drive board 300, not only can the power supply board 700, the control board 200 and the drive board 300 be prevented from coming off the housing 100, but the power supply board 700, the control board 200 and the drive board 300 can be prevented from colliding and being damaged, and interference of the power supply board 700, the control board 200 and the drive board 300 with electronic devices outside the vehicle controller 1 can be avoided.

[0070] In some specific embodiments of the present disclosure, as shown in FIG. 8, a first electrical protection element 710 is connected to the positive power line of the power supply board 700, and the first electrical protection element 710 is connected to the DC plug connector 110.

[0071] For example, the first electrical protection element 710 may be a fuse. In this way, if the current or voltage transmitted by the positive power line is too large, the first electrical protection element 710 itself will fuse to cut off the circuit and cut off the transmission of current to the power supply board 700, thereby protecting the power supply board 700 and preventing damage to the power supply board 700 due to excessive current.

[0072] 5 , the outer circumferential surface of the DC relay pin 811 is surrounded by a second magnetic ring 812. The second magnetic ring 812 may be fitted onto the DC relay pin 811. By adding the second magnetic ring 812, noise caused by the current flowing through the DC relay pin 811 can be effectively suppressed, and fluctuations in the DC current output by the DC output plug connector 814 can be further reduced.

[0073] In some specific embodiments of the present disclosure, as shown in Figures 6 and 7, an AC shielding chamber 154, a power line shielding chamber 151, a power signal line shielding chamber 152, and a DC output shielding chamber 153 are installed on the side of the housing 100 facing the power board 700.

[0074] The conductors of AC output plug connector 800 are located in AC shielding chamber 154, which accommodates the conductors of AC output plug connector 800, preventing physical interference between the conductors and other components and ensuring a more stable electrical connection. An AC shielding plate is attached to housing 100, which covers AC shielding chamber 154. That is, AC shielding chamber 154 accommodates the conductors together with the AC shielding plate, preventing the conductors from leaving AC shielding chamber 154 and reducing electronic noise emitted by the conductors outside AC shielding chamber 154.

[0075] The positive and negative power lines are located within power line shielding chamber 151, and power signal line 780 is located within power signal line shielding chamber 152. Power line shielding chamber 151 houses the positive and negative power lines, preventing physical interference between the two power lines and other components and providing a more stable electrical connection. Power line cover plate 155 covers power line shielding chamber 151, and signal line cover plate 156 covers power and signal line shielding chamber 152. This not only prevents the two power lines from detaching from power line shielding chamber 151, but also reduces electronic noise emitted by power line shielding chamber 151.

[0076] The DC relay pin 811 and the DC filter plate 813 are located within the DC output shielding chamber 153, which accommodates the DC relay pin 811 and the DC filter plate 813, preventing physical interference between the DC relay pin 811 and the DC filter plate 813 and other components and ensuring a more stable electrical connection. A DC shielding plate 171 is attached to the housing 100 and covers the DC output shielding chamber 153 to ensure the shielding effect of the DC output shielding chamber 153 and prevent the DC relay pin 811 and the DC filter plate 813 from detaching from the DC output shielding chamber 153.

[0077] By spacing the chambers apart, mutual interference between the electronic devices can be avoided, further optimizing electromagnetic compatibility.

[0078] In some specific embodiments of the present disclosure, as shown in FIG. 5 , the power supply substrate 700 includes a substrate body 720, an AC inductor 730, a DC inductor 740, a transformer inductor 750, a transformer 760, and a MOS transistor 770.

[0079] The positive power line, the negative power line, the power signal line 780, the AC relay terminal, and the DC relay terminal are all installed on the substrate body 720. The AC inductor 730 and the DC inductor 740 are attached to both sides of the substrate body 720 in the width direction. The AC inductor 730, the DC inductor 740, and the power signal line 780 are located at the same end of the substrate body 720 in the length direction of the substrate body 720, and the transformer 760 is attached to the substrate body 720 and is located between the AC inductor 730 and the DC inductor 740 in the width direction of the substrate body 720. The transformer 760 is attached to the substrate body 720 and is located at one end of the substrate body 720 away from the power signal line 780. The MOS transistors 770 are attached to the substrate body 720 and are located on both sides of the transformer 760 in the width direction of the substrate body 720.

[0080] The above-mentioned multiple power lines, multiple inductors, power signal lines 780, and multiple MOS transistors 770 are integrated into the substrate body 720, that is, multiple electronic devices can be mounted simultaneously on one substrate body 720. This makes the power supply substrate 700 highly integrated, and the entire power supply substrate 700 can be attached and detached simply by attaching and detaching the substrate body 720.

[0081] By arranging 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 is increased, thereby reducing electromagnetic interference between the transformer 760 and the power signal line 780. In addition, the layout of the power supply board 700 makes the structure of the power supply board 700 more compact, which helps to reduce the volume of the power supply board 700.

[0082] In this way, the power supply substrate 700 is not only capable of outputting DC and AC current, but also the voltage of the output DC current differs from the voltage of the input DC current.

[0083] In some embodiments of the present disclosure, as shown in FIG. 6 , a DC inductor shielding chamber 160, an AC inductor shielding chamber 161, a transformer inductor shielding chamber 162, and a MOS transistor shielding chamber 163 are installed on the side of the housing 100 facing the power supply board 700.

[0084] The DC inductor 740 is located in the DC inductor shielded chamber 160, the AC inductor 730 is located in the AC inductor shielded chamber 161, the transformer inductor 750 is located in the transformer inductor shielded chamber 162, and the MOS transistor 770 is located in the MOS transistor shielded chamber 163. By providing multiple independent shielded chambers, the AC inductor 730, the DC inductor 740, the transformer inductor 750, and the MOS transistor 770 can be located in different shielded chambers, respectively, which reduces the electromagnetic interference between the AC inductor 730, the DC inductor 740, the transformer inductor 750, and the MOS transistor 770, and also reduces the electromagnetic interference to the outside world, which helps improve the overall electromagnetic compatibility.

[0085] In addition, the substrate body 720 covers the DC inductor shielding chamber 160, the AC inductor shielding chamber 161, the transformer inductor shielding chamber 162, and the MOS transistor shielding chamber 163, which can prevent the transformer, multiple inductors, and multiple MOS transistors 770 from detaching from their respective shielding chambers, resulting in high positional stability.

[0086] In some specific embodiments of the present disclosure, as shown in Figures 1 and 2, a removable maintenance plate 180 is attached to the housing 100, a first electrical connector 181 is attached to the maintenance plate 180, and a second electrical connector 182 that is in contact with and conductive with the first electrical connector 181 is attached to the housing 100, and a control board 200 detects the on / off of the first electrical connector 181 and the second electrical connector 182 to control the on / off of the circuit of the energy storage element.

[0087] For example, the maintenance plate 180 may be removably attached to the second cover plate 910, the first electrical connector 181 may be attached to the side of the maintenance plate 180 facing the housing 100, and the second electrical connector 182 may be attached to the capacitor 500; in this way, when the maintenance plate 180 is attached to the housing 100, the first electrical connector 181 and the second electrical connector 182 are electrically conductive, and the vehicle controller 1 operates normally. When maintenance or inspection is required for the vehicle controller 1, the maintenance plate 180 is first removed, at which time the first electrical connector 181 and the second electrical connector 182 are separated, and 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 contactor may be installed between the energy storage element and the DC plug connector 110, and 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 contactor between the energy storage element and the DC plug connector 110 to disconnect it, thereby cutting off the power supply to the entire vehicle controller 1, thereby protecting the safety of the service technician and facilitating maintenance and inspection of the vehicle controller 1.

[0088] In some specific embodiments of the present disclosure, as shown in FIG. 1, the vehicle controller 1 further includes a DC plug connector 110 and a power supply plug connector 920.

[0089] The DC plug connector 110 is attached to the housing 100 and connected to the energy storage element. The power supply plug connector 920 is attached to the housing 100 and exposed from the housing 100. A positive electrode heating wire and a negative electrode heating wire are connected to the power supply plug connector 920, and both the positive electrode heating wire and the negative electrode heating wire are connected to the DC plug connector 110. The power supply plug connector 920 is connected to a heating member for heating the energy storage element.

[0090] After the power supply plug connector 920 is connected to the energy storage element and the heating element to establish electrical conduction, the energy storage element can supply power to the heating element via the power supply plug connector 920 to cause the heating element to generate heat, and the heating element can be positioned close to the energy storage element to heat it. As can be understood, in a low temperature environment, for example in winter, the storage characteristics and power supply characteristics of the energy storage element may deteriorate, which may affect the running of the vehicle. By adding a heating element, it is possible to ensure that the temperature of the energy storage element is appropriate and ensure the usage characteristics of the energy storage element.

[0091] In some specific embodiments of the present disclosure, as shown in Figure 8, a third magnetic ring 190 is attached to the housing, and both the positive and negative heating wires pass through the third magnetic ring 190. This can suppress noise caused by the current flowing through the positive and negative heating wires, stabilize the current output to the heating element, and prevent damage to the heating element.

[0092] A second electrical protection element 921 is connected to the positive heating wire and is connected to the DC plug connector 110. The second electrical protection element 921 may be a fuse. When the current flowing through the positive heating wire is too large, the second electrical protection element 921 melts to cut off the circuit, cutting off current transmission and protecting the heating element from damage caused by excessive current.

[0093] Preferably, the power supply plug connector 920 is connected to the compressor of the vehicle's air conditioner. In this way, the energy storage element can supply power to the compressor and the heating element simultaneously by connecting the power supply plug connector 920 to the compressor, thereby not only allowing the compressor to operate normally to regulate the internal temperature of the vehicle but also allowing the heating element to heat, thereby improving the utilization rate of the power supply plug connector 920 and reducing the number of parts in the vehicle controller 1.

[0094] Hereinafter, a vehicle according to an embodiment of the present disclosure will be described with reference to the drawings.

[0095] The vehicle according to the embodiment of the present disclosure includes the vehicle controller 1 according to the above embodiment of the present disclosure, a power box 2, a motor, a transmission, and an energy storage element.

[0096] The power box 2 is attached to the housing 100 of the vehicle controller 1, the motor and the transmission are connected to each other in a transmissive manner and attached to the power box 2, and the motor is connected to the IGBT module 530. For example, the power box 2 is located on the side of the power supply board 700 facing away from the housing 100, and the power box 2 can fix and shield the motor and the transmission to prevent damage to the motor and the transmission.

[0097] The motor is electrically connected to the driving board 300, which can drive the operation of the motor. The energy storage element is connected to the output terminal of the on-off element 400. The current of the external power supply flows to the energy storage element through the on-off element 400 to charge the energy storage element. The on-off element 400 is installed between the energy storage element and the external power supply and can effectively control the on / off between the external power supply and the energy storage element to protect the energy storage element from being overcharged.
