Referring to fig. 1, an embodiment of the present application provides a vehicle-mounted power supply system 10. The in-vehicle power supply system 10 includes a power distribution module 120 and a Micro Controller Unit (MCU) 140 connected to the power distribution module 120. The power distribution module 120 is configured to electrically connect the load 16 and the power source 15, the power distribution module 120 including a smart switch 121, the smart switch 121 being connected between the load 16 and the power source 15. The intelligent switch 121 is configured to control the operating state of the load 16. The micro control unit 140 is configured to control the on/off state of the smart switch 121.
The vehicle-mounted power supply system 10 of the embodiment of the present application adopts the micro control unit 140 to control the on-off state of the intelligent switch 121, so as to control the working state of the load 16, and compared with a scheme that a relay is adopted in the related art, the vehicle-mounted power supply system 10 of the embodiment of the present application occupies a small volume.
Specifically, the on-board power supply system 10 is used to supply power to a load 16 of an automobile. The functions of the vehicle-mounted power supply system 10 include, but are not limited to, controlling the on/off of power supply, monitoring the state of each power supply loop, performing fault diagnosis and fault identification on each power supply loop, storing and reporting fault information in the loops to the micro control unit 140, and performing pre-alarming and processing on faults in the loops.
More specifically, the vehicle-mounted power supply system 10 can freely control the on/off of the power supply, and when the voltage or current at a certain place of the whole vehicle is abnormal, the vehicle-mounted power supply system 10 can disconnect the power distribution module 120 to control the on/off of the power supply. The vehicle-mounted power supply system 10 can monitor the state of each power supply loop, and the vehicle-mounted power supply system 10 monitors whether a circuit is maintained in the loop or whether a problem of disconnection, short circuit and the like exists in the loop in real time and feeds the problem back to the micro control unit 140.
The on-board power supply system 10 can perform fault diagnosis and fault identification on each power supply loop, and the diagnosis and identification contents include but are not limited to power supply open circuit, short circuit to the power supply 15, loop overcurrent, power supply overvoltage and the like. The vehicle-mounted power supply system 10 can store fault information in the loop and report the fault information to the micro control unit 140, and after the current loop of the automobile has a problem, the vehicle-mounted power supply system 10 stores the fault information and uploads the fault information to the micro control unit 140 so as to more rapidly process the same fault condition next time.

The functional circuit of the on-board power supply system 10 may be provided on the power distribution module 120. The power distribution module 120 is controlled by the mcu 140, and the power distribution module 120 can also control the functional circuits disposed on the power distribution module 120. Specifically, if the power supply voltage and the current are abnormal and the abnormal condition does not damage the power distribution module 120 or other circuit modules of the vehicle in a short time, the power distribution module 120 transmits the information of the abnormal condition to the micro control unit 140, and the micro control unit 140 processes the information and obtains a processing result to be transmitted to the power distribution module 120 for implementation. If the supply voltage and current are abnormal to a serious degree and even damage the car or the power distribution module 120, the power distribution module 120 can individually and quickly respond, including but not limited to increasing the resistance to realize overvoltage protection, cutting off the supply circuit (controlling the input current) and controlling the intelligent switch 121 to cut off the current output circuit (controlling the output current).
The micro control unit 140 may be a single chip microcomputer, and the micro control unit 140 has a function of integrally controlling all loops of the vehicle. The power distribution module 120 is controlled by the micro control unit 140. The functions of the mcu 140 include, but are not limited to, processing data monitored by the power distribution module 120, issuing an instruction to the power distribution module 120 whether a loop is powered on or off, storing fault information and log generation in the loop, and the like.
The power supply 15 is responsible for supplying power to the load 16, and the power supply 15 acts indirectly on the load 16. The current output from the power source 15 to the load 16 needs to pass through the power distribution module 120, and after passing through the power distribution module 120, the micro control unit 140 or the power distribution module 120 determines whether to input the current to the load 16. Specifically, the type of the power source 15 may be various, for example, the power source 15 may be a nickel cadmium battery, a nickel hydrogen battery, a lithium ion battery, and the like, and the embodiment of the present application is not limited.
The load 16 is a direct acting object of the power distribution module 120, and the current input to the load 16 can be freely controlled by the power distribution module 120. Specifically, the load 16 may be a specific functional circuit of a vehicle, for example, the load 16 may be a circuit of a vehicle air conditioner, a vehicle player, or a vehicle motor. The load 16 may include an electric motor, a lamp, or other power consuming components. The operating state of load 16 may include being operated or being out of operation.
The power distribution module 120 is provided with an intelligent switch 121, and the intelligent switch 121 can control the on/off of the current input to the load 16. The intelligent switch 121 may be controlled directly by the power distribution module 120 and indirectly by the micro control unit 140.
Referring to fig. 2, in some embodiments, the power distribution module 120 includes a current limiter 122 coupled to the intelligent switch 121, the current limiter 122 configured to limit the input current of the intelligent switch 121.
As such, the current limiter 122 coupled to the intelligent switch 121 limits the current input to the intelligent switch 121 to protect the intelligent switch 121 when the current condition is abnormal. The current limiter 122 makes the intelligent switch 121 not easy to damage, so that the intelligent switch 121 can be repeatedly used for a long time without frequent replacement, and the maintenance cost is saved.
Specifically, the current limiter 122 may cause the intelligent switch 121 to automatically power off to protect the device when the current exceeds a set current, the type of the current limiter 122 may be various, including but not limited to a fault current limiter, a stator current limiter, and the like.
Referring to fig. 3, in some embodiments, the singulation module 120 includes a voltage limiter 123 coupled to the intelligent switch 121, the voltage limiter 123 configured to limit an input voltage of the intelligent switch 121.
Thus, the voltage limiter 123 coupled to the intelligent switch 121 reduces the resistance value to limit the voltage of the intelligent switch 121 when the voltage condition of the intelligent switch 121 is abnormal. The voltage limiter 123 enables the intelligent switch 121 not to be damaged easily, so that the intelligent switch 121 can be used repeatedly and for a long time without being replaced frequently, and maintenance cost is saved.
Specifically, when the voltage of the smart switch 121 exceeds the set value, the voltage limiter 123 may limit the voltage of the smart switch 121 by decreasing the resistance value of the voltage dependent resistor.
Referring to fig. 4, in some embodiments, the power distribution module 120 includes a voltage monitoring circuit 124, the voltage monitoring circuit 124 is configured to monitor the voltage output to the load 16, and the micro control unit 140 is configured to control the on/off state of the intelligent switch 121 according to the voltage output to the load 16.
In this way, the voltage monitoring circuit 124 can feed back the monitored voltage condition to the power distribution module 120 and the micro control unit 140, so that the power distribution module 120 can quickly perform the processing or the micro control unit 140 can control the power distribution module 120 to perform the processing.
In particular, the voltage monitoring circuit 124 may be disposed at an input of the power source 15 coupled to the power distribution module 120 and may be disposed at an output of the power distribution module 120 coupled to the load 16. The voltage monitoring circuit 124 may continuously feed back the voltage conditions of the input terminal and the output terminal to the power distribution module 120 and the micro control unit 140, if the voltage is abnormal, but the abnormal conditions are not enough to damage the power distribution module 120, the load 16 or the vehicle-mounted power supply system 10, the voltage conditions monitored by the voltage monitoring circuit 124 are processed by the micro control unit 140, and the micro control unit 140 takes measures after processing the voltage conditions. If the voltage is abnormal, but the abnormal condition is so serious that the power distribution module 120, the load 16 or the vehicle-mounted power supply system 10 is damaged, the voltage condition monitored by the voltage monitoring circuit 124 is handed to other modules of the power distribution module 120 for processing, the processing mode includes, but is not limited to, overvoltage protection, module restart, power supply disconnection and the like, and the processing information is fed back to the micro control unit 140, and the micro control unit 140 controls other modules of the vehicle to take corresponding measures.
Referring to fig. 5, in some embodiments, the power distribution module 120 includes a current monitoring circuit 125, the current monitoring circuit 125 is configured to monitor the current output to the load 16, and the micro control unit 140 is configured to control the on/off state of the intelligent switch 121 according to the current output to the load 16.
In this way, the current monitoring circuit 125 can feed back the monitored current condition to the power distribution module 120 and the micro control unit 140, so that the power distribution module 120 can quickly perform the processing or the micro control unit 140 can control the power distribution module 120 to perform the processing.
Specifically, the current monitoring circuit 125 may be disposed at an output of the power distribution module 120 that is connected to the load 16. The current monitoring circuit 125 may monitor the current condition of the load 16 and feed the current condition back to the power distribution module 120 and the micro control unit 140, and if the current is abnormal, for example, the current value is too large, and the power distribution module 120 or the circuit in the load 16 may be burned, the power distribution module 120 may quickly make a countermeasure after receiving the feedback information, where the countermeasure includes, but is not limited to, disconnecting the smart switch 121, short-circuiting the power supply, short-circuiting the ground, and the like. The power distribution module 120 feeds back the processing information to the micro control unit 140, and the micro control unit 140 controls other modules of the vehicle to take corresponding measures, such as starting the used power supply or cutting off the power of the entire vehicle. If the current is abnormal and the degree of the current abnormality is not large enough to damage the power distribution module 120 or the load 16, the current condition monitored by the current monitoring circuit 125 is processed by the micro control unit 140, and the micro control unit 140 performs a countermeasure after analyzing and processing the current condition, such as controlling the intelligent switch 121 and applying an overcurrent protection measure.
However, when the abnormal condition is not enough to damage the power distribution module 120, the load 16 or the vehicle-mounted power supply system 10, the voltage condition monitored by the voltage monitoring circuit 124 is processed by the micro-control unit 140, and the micro-control unit 140 takes measures after processing the voltage condition. If the voltage is abnormal, but the abnormal condition is so serious that the power distribution module 120, the load 16 or the vehicle-mounted power supply system 10 is damaged, the voltage condition monitored by the voltage monitoring circuit 124 is handed to other modules of the power distribution module 120 for processing, the processing mode includes, but is not limited to, overvoltage protection, module restart, power supply disconnection and the like, and the processing information is fed back to the micro control unit 140, and the micro control unit 140 controls other modules of the vehicle to take corresponding measures.
Referring to fig. 6, in some embodiments, the power distribution module 120 includes a filter circuit 126 disposed between the load 16 and the smart switch 121.
In this way, the filter circuit 126 can eliminate interference of other components to the load 16, so that the operation of the load 16 is more stable.
Specifically, the filter circuit 126 may effectively filter a frequency point of a specific frequency in the power line or frequencies other than the frequency point to obtain a power signal of the specific frequency, or eliminate the power signal of the specific frequency. In one example, the current delivered to the load 16 from the power source 15 may be disturbed by circuit components of the power distribution module 120, resulting in a power signal that is not frequency stabilized and that is delivered directly to the load 16, but the power signal that passes through the filtering circuit 126 may filter out the disturbance frequency so that the load 16 receives a correct and stable power signal.
Referring to fig. 7, in some embodiments, the power distribution module 120 includes a controller 127 disposed between the smart switch 121 and the micro-control unit 140. The controller 127 is configured to receive a control instruction sent by the micro control unit 140, and control the on/off state of the intelligent switch 121 according to the control instruction.
As such, the mcu 140 may indirectly control the power distribution module 120 via the controller 127.
Specifically, in one example, the controller 127 directly controls the smart switch 121 to control the switching of the power supply load 16. When the voltage or the current of the power distribution module 120 is abnormal, the voltage monitoring loop 124 and the current monitoring loop 125 in the power distribution module 120 feed back the monitoring information to the micro control unit 140 for analysis and processing, after the micro control unit 140 analyzes and processes, a command whether the intelligent switch 121 should be switched on or off is given to the controller 127 for processing, and the controller 127 directly controls the intelligent switch 121 to be switched on or off.
In some embodiments, the controller 127 is coupled with the electrostatic protection unit 131, and the electrostatic protection unit 131 can eliminate static electricity, prevent static electricity from interfering with the controller 127, and ensure that the controller 127 executes a correct command of the micro control unit 140.
Referring to fig. 8, in some embodiments, the power distribution module 120 includes a reverse protection circuit 128 disposed between the smart switch 121 and the power source 15, the reverse protection circuit 128 configured to protect the power distribution module 120 in the event that the power source 15 is reverse connected to the power distribution module 140.
In this manner, the reverse protection circuit 128 may protect the power distribution module 120 from being burned or damaged by excessive current in the event that the power source 15 is reverse connected.
Specifically, the reverse protection circuit 128 may be disposed at the connection of the power source 15 and the power distribution module 120, and when the power source 15 is reversely connected, the reverse protection circuit 128 may protect the power distribution module 120 by cutting off a loop, limiting current, and the like.
Referring to fig. 9, in some embodiments, the power distribution module 120 includes an overvoltage protection unit 129, and the overvoltage protection unit 129 is configured to protect the entire power distribution module 120 when the supply voltage of the power source 15 is greater than the voltage threshold.
Specifically, the overvoltage protection unit 129 can turn off the power source 15 or reduce the voltage of the power distribution module 120 to protect the power distribution module 120 when the power supply voltage of the power source 15 is greater than the voltage threshold. The overvoltage protection unit 129 may be a varistor, a lightning arrester, and the like. In one example, the overvoltage protection unit 129 is a voltage dependent resistor, and when an excessive voltage occurs in the power distribution module 120, the resistance of the voltage dependent resistor may become infinitesimal, such that the voltage dependent resistor is turned on and introduces a current generating a high voltage into the ground for overvoltage protection.
Referring to fig. 10, in some embodiments, the power distribution module 120 includes an overheat protection unit 132.
Thus, when the power distribution module 120 generates heat seriously due to excessive current, the overheating protection unit 132 can protect the power distribution module 120
Specifically, the overheating protection unit 132 may prevent the power distribution module 120 from being burnt or being electrically damaged by cutting off the circuit. When the temperature of the power distribution module 120 is reduced to a normal range, the overheat protection unit 132 may close the circuit and restore the normal operation state. The overheating protection unit 132 may also be equipped with a cooling water passage, and when the power distribution module 120 is overheated, the temperature of the power distribution module 120 is reduced by circulating the cooling water passage after the circuit is opened, and then the overheating protection unit 132 closes the circuit again to restore the normal operation state.
Referring to fig. 11, in some embodiments, the power distribution module 120 includes an intelligent restart unit 133.
In this manner, the power distribution module 120 may be restarted by the intelligent restart unit 133 under certain use conditions.
Specifically, when the power distribution module 120 functions abnormally or the overheating is severe, the power distribution module 120 may be restarted through the intelligent restart unit 133, the function of the power distribution module 120 may be reset, and the temperature of the power distribution module 120 may be lowered.

Meanwhile, the on-board power supply system 10 may pool the loads 16 of the vehicle 100, so that the vehicle 100 has lower maintenance cost and higher intelligence compared to an automobile with a conventional relay scheme.
