It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Referring to fig. 1, a block diagram of a monitored power distribution system for a vehicle of the present invention is shown. The monitored power distribution system of the vehicle may include: the monitoring and converting module 110, the main control module 120, the monitoring and transmitting module 130 and the battery module 140. The input end of the monitoring conversion module 110 is connected to the output end of the battery module 140, and is configured to output a first power supply signal to the main control module 120 according to a first voltage signal output by the battery module 140 when it is monitored that the vehicle is in a target parking state; the main control module 120 is connected to the monitoring transmission module 110, and configured to monitor battery failure information based on the first power supply signal, and output the battery failure information to the monitoring transmission module 130; and the monitoring transmission module is used for sending the battery fault information through a network.

Specifically, the input terminal of the monitoring conversion module 110 may be connected to the output terminal of the battery module 140, so that the monitoring conversion module 110 may output a first power supply signal to the main control module 120 according to a first voltage signal output by the battery module 140. In addition, the main control module 120 may be connected to the monitoring transmission module 130, so as to transmit the monitored battery fault information to the monitoring transmission module 130, so that the monitoring transmission module 130 may receive the battery fault information and may send the battery fault information out through a network, so that the background monitoring platform may receive the battery fault information through the network, thereby monitoring the state of the battery system in real time, and further enabling the vehicle battery system to be in a controlled state all the time.

As an example of the present invention, the monitoring conversion module 110 may be a DCDC monitoring conversion module, the DCDC monitoring conversion module is connected to an output end of the battery module 140, and the battery module 140 may output a first voltage signal to the DCDC monitoring conversion module to provide a first voltage to the DCDC monitoring conversion module, so that the DCDC monitoring conversion module may perform voltage conversion according to the first voltage signal when monitoring that the vehicle is in a parking state or a charging state, and output the voltage signal obtained after the conversion to the main control module 120 as a first power supply signal, so as to convert the voltage provided by the battery module 140 into a power supply voltage to supply power to the main control module 120, so that the main control module 120 may monitor the battery module 140 to monitor battery fault information of the battery module 140. The main control module 120 may output the monitored battery failure information to the monitoring transmission module 130, and the monitoring transmission module 130 may transmit the battery failure information through a network.

In summary, in the embodiment of the present invention, the input end of the monitoring conversion module 110 is connected to the output end of the battery module 140, and the output end of the monitoring conversion module 110 is connected to the main control module 120, so that the monitoring conversion module 110 converts the first voltage signal provided by the battery module 140 into the first power supply signal and outputs the first power supply signal to the main control module 120, thereby supplying power to the main control module 120, so that the main control module 120 can monitor the battery module in the battery module 140, and thus, the state of the battery system can be monitored in real time when the vehicle is parked for a long time, and the vehicle battery system is always in a controlled state.

It can be seen that, in the embodiment of the present invention, after the monitoring conversion module 110 provides the first power supply signal to the main control module 120, the main control module 120 can monitor the battery module 140 according to the first power supply signal to obtain the battery fault information of the battery module 140, and output the battery fault information of the battery module 140 to the monitoring transmission module 130 to trigger the monitoring transmission module 130 to send the battery fault information through the network, so as to implement real-time monitoring and send the battery fault information of the vehicle, solve the problem of failure of the monitoring function of the monitoring power distribution system due to power failure or power supply abnormality of the BMS system in the monitoring power distribution system of the vehicle in the prior art, and improve the safety and reliability of the overall design of the battery system.

In a specific implementation, optionally, the monitoring conversion module 110 may convert the first voltage signal provided by the output end of the battery module 140 into a first power supply signal required by the main control module 120 according to the power consumption requirement of the main control module 120, for example, if the voltage value corresponding to the first voltage signal provided by the output end of the battery module 140 is a high voltage of 580V, and the voltage required by the main control module 120 is a low voltage of 24V, the monitoring conversion module 110 may convert the first voltage signal provided by the output end of the battery module 140 and having a corresponding voltage value of 580V into a first power supply signal having a corresponding voltage value of 24V, and provide the first power supply signal to the main control module 120 to supply power to the main control module 120, and the main control module 120 may monitor the battery module 140 according to the first power supply signal provided by the monitoring conversion module 110, to acquire battery failure information of the battery module 140. Specifically, the battery fault information of the battery module 140 may be a current battery voltage, a battery standard voltage, a current battery temperature, a battery current, a usage time, an operating time, a battery capacity, and the like of the battery module 140, which is not limited in this example. After acquiring the relevant battery failure information, the main control module 120 may transmit the battery failure information to the monitoring transmission module 130, and then the monitoring transmission module 130 may send the received battery failure information by using a network.

In an alternative embodiment of the present invention, the monitoring power distribution system may further include a rectifying and isolating module 150 and a battery module 160. A first input end of the rectification isolation module 150 is connected with the storage battery module 160, and a second input end of the rectification isolation module 150 is connected with an output end of the monitoring conversion module; the storage battery module 160 is configured to output a second power supply signal to the rectifying and isolating module 150 when the vehicle is in the non-target parking state; the rectifying and isolating module 150 is configured to transmit the first power supply signal or the second power supply signal to the main control module 120 to supply power to the main control module 120.

In a specific implementation, as shown in fig. 2, a first input end of the rectifying and isolating module 150 may be connected to the battery module to transmit a second power supply signal output by the battery module 160 to the main control module 120, so as to supply power to the main control module 120, and to supply power to the main control module 120 through the battery module 160 when the vehicle is in a non-target parking state. A second input end of the rectifying and isolating module 150 may be connected to the monitoring and converting module 110, so as to provide the first power supply signal output by the monitoring and converting module 110 to the main control module 120, supply power to the main control module 120, and supply power to the main control module 120 through the monitoring and converting module when the vehicle is in the target parking state.

As an example of the present invention, the battery module 160 may output a second power supply signal to the main control module 120 through the rectifying and isolating module 150, where a voltage value corresponding to the second power supply signal may be a voltage value required by the current main control module 120, and if the voltage value required by the current main control module 120 is 24V, a voltage value corresponding to the second power supply signal may be 24V, and at this time, the battery module 160 may be a low-voltage battery with an output voltage value of 24V.

It can be seen that, in this embodiment, when the vehicle is in the target parking state or the non-target parking state, the rectification isolation module 150 transmits the first power supply signal and/or the second power supply signal to the main control module 120, so as to supply power to the main control module 120, and at the same time, isolate the first power supply signal output by the monitoring conversion module 110 from the second power supply signal output by the storage battery module 160, so that the main control module 120 can monitor the battery module 140 based on the first power supply signal and/or the second power supply signal, so as to obtain the current battery fault information of the battery module 140, and then output the current battery fault information of the battery module 140 to the monitoring transmission module 130, and the monitoring transmission module 130 can transmit the battery fault information through the network, so that when the vehicle is parked or driven or charged for a long time, the state of the battery system can be monitored in real time, so that the vehicle battery system is always in a controlled state.

Further, in the embodiment of the present invention, the monitoring conversion module 110 and the storage battery module 160 may supply power to the output power signal of the main control module 120 through the rectification isolation module 150, and the output power signal may be determined based on the detection result of the current driving or charging state of the vehicle. Specifically, when it is detected that the current vehicle is in a driving state or a charging state, it may be determined whether the vehicle is currently in the driving state or the charging state by detecting whether the current vehicle has a corresponding driving signal or charging signal, for example.

As an example of the present application, when the corresponding driving signal or the charging signal is detected, the monitoring conversion module 110 may enter a sleep state, and does not output the first power supply signal to the main control module 120. At this time, the storage battery module 160 may output a second power supply signal to the main control module 120 through the rectification isolation module 150, so that the main control module 120 can monitor the battery module 140 according to the second power supply signal to monitor the battery fault information corresponding to the battery module 140. When the vehicle is detected to be in a parking state, if the driving signal or the charging signal is detected to be an invalid signal, that is, if no valid driving signal or charging signal is detected, the storage battery module 160 may stop outputting the second power supply signal to the main control module, the monitoring and converting module 110 may perform voltage conversion on the first voltage signal output by the battery module 140, and output the voltage signal obtained after the voltage conversion as the first power supply signal to the rectifying and isolating module 150, so as to provide the first power supply signal to the main control module 120 through the rectifying and isolating module 150, so as to supply power to the main control module 120, so that the main control module 120 may normally operate, for example, the main control module 120 may send a control message to the monitoring and converting module 110, so that the monitoring and converting module 110 may supply power to the main control module according to a preset DC/DC power-up and power-down strategy, to ensure that the main control module 120 can operate properly. The main control module 120 may send the control packet to the monitoring conversion module 110 through a local area network or other communication methods, which is not limited in this example.

In the actual processing, the control packet sent by the main control module 120 may include the wake-up signal and the wake-up time of the monitoring conversion module 110, and the monitoring conversion module 110 may control whether to wake up itself currently and output the first power supply signal to the main control module 120 according to the wake-up signal and the wake-up time included in the control packet; the wake-up time may be used to wake up the monitoring converting module 110 in the sleep state to supply power to the main control module 120, for example, the wake-up time may be 1 hour, 2 hours, 4 hours, or 8 hours, which is not limited in this example.

For example, in the case that the preset wake-up time is 8 hours, when the wake-up time reaches 8 hours, the wake-up times after the monitoring and converting module 110 may be all 8 hours until the wake-up time is recalculated when the driving signal or the charging signal is detected again. In addition, the time for supplying power to the main control module 120 after the monitoring conversion module 110 wakes up may be set to 5min, or may be set to other times, which is not limited in this example.

Further, the monitoring conversion module 110 may determine whether the master control module 120 is disconnected through a preset control message waiting duration threshold, so as to convert the first voltage signal output by the power module 140 into a first power supply signal under the disconnection condition, output the first power supply signal to the rectification isolation module 150, transmit the first power supply signal to the master control module 120 through the rectification isolation module 150, supply power to the master control module 120, and ensure that the master control module 120 can normally operate. The message waiting duration threshold of the monitoring conversion module may be set according to the battery monitoring requirement, for example, may be set to 5 seconds or 10 seconds, and the present invention is not limited thereto.

For example, when the main control module 120 has a fault, such as a communication fault or a power supply fault of the main control module 120, the monitoring module 110 does not receive the control message sent by the main control module 120 within a preset control message waiting time threshold, at this time, the monitoring conversion module 110 may consider that the main control module is disconnected, and in order to ensure normal power supply of the main control module 120, the monitoring conversion module 110 may supply power to the main control module through a preset DC/DC power-on/power-off strategy. Specifically, if the monitoring conversion module 110 is currently in the sleep state, the monitoring conversion module 110 may be waken up to output the first power supply signal to the main control module 120 to supply power to the main control module 120, and when the monitoring conversion module 110 is currently in the waken state, the monitoring conversion module 110 is supplying power to the main control module 120 at this time, the time for supplying power to the main control module 120 by the monitoring conversion module 110 may be prolonged, and if the power supply time of the monitoring conversion module 110 may be prolonged by 30 seconds on the basis of the original power supply time, which is not limited in this example.

Further, the main control module 120 may preset an extreme fault control strategy, and when the main control module 120 detects that an extreme fault such as overvoltage, overtemperature, insulation fault, fire early warning, etc. occurs in the current battery module, the main control module 120 may make a corresponding control measure according to the preset extreme fault control strategy. Specifically, when an extreme fault is detected, the main control module 120 may send a control packet to the monitoring conversion module 110, the monitoring conversion module 110 may output a first power supply signal to the main control module 120 according to the control packet to continuously supply power to the main control module 120, so that the main control module 120 can continuously monitor the battery module 140, so as to transmit the monitored battery fault information corresponding to the battery module 140 to the monitoring transmission module 130, so that the monitoring transmission module 130 may receive the battery fault information and send the battery fault information through a network, so that a background monitoring platform may receive the battery fault information through the network, and then may take a countermeasure according to the battery fault information, during which the monitoring conversion module may continuously output the first power supply signal to the main control module 120 until the current fault disappears.

In addition, the monitoring conversion module 110 may further have an under-voltage protection function, for example, the monitoring conversion module 110 may set a voltage protection value, and when the voltage value corresponding to the first voltage signal output by the current power module 140 is lower than the preset voltage protection value, the monitoring conversion module 110 may not perform voltage conversion, that is, the first power supply signal is not output to the rectifying and isolating module 150 based on the first voltage signal, and the monitoring conversion module enters a shutdown state, and is not automatically waken up any more, so as to determine power supply safety.

It can be seen that the monitoring power distribution system of the vehicle in the embodiment of the utility model can determine the state of the vehicle according to the current target parking turntable or non-target parking state of the vehicle, the first power supply signal and/or the second power supply signal are transmitted to the main control module 120 through the rectification isolation module 150, so that isolated power supply is realized, the safe power supply of the main control module 120 is ensured, so that the main control module 120 can monitor the battery failure information in real time when the vehicle is in a target parking state or a non-target parking state, the state of the battery system can be monitored in real time, so that the vehicle battery system is always in a controlled state, the power failure condition in the switching process of the output voltage of a DCDC module of a monitoring power distribution system of a vehicle and the low voltage output by the whole vehicle in the prior art is solved, the BMS master control cannot work normally due to abnormal power supply, so that the whole monitoring system is in a paralyzed state, and the battery system of the vehicle is not controlled.

In a specific implementation, optionally, the rectification isolation module 150 may include a first diode 1501 and a second diode 1502, wherein an anode of the first diode is connected to the battery module, and a cathode of the first diode is connected to the main control module; the anode of the second diode is connected with the monitoring conversion module, and the cathode of the second diode is connected with the main control module. As shown in fig. 2, in the embodiment of the present invention, each of the first diode 1501 and the second diode 1502 may be a diode having unidirectionality, an anode of the first diode 1501 is connected to the battery module 160, and a cathode of the first diode 1501 is connected to the main control module 120, and may be used to control a second power supply signal output by the battery module 160 to flow to the main control module 120; the anode of the second diode 1502 is connected to the monitoring conversion module 110, and the cathode of the second diode 1502 is connected to the main control module 120, and may be used to control the first power supply signal output by the monitoring conversion module 110 to flow to the main control module 120. This example realizes the isolation of first power supply signal and second power supply signal through first diode 1501 and second diode 1502, and control power supply signal flow to master control module 120, in order to supply power for master control module 120, realized that the vehicle is in the state of going or not going, can supply power to master control module 120, ensure that master control module 120 can normally work, make master control module 120 can real time monitoring battery system's state, and then solved prior art and can't be in the problem that paralyzed state leads to the whole monitored control system of vehicle for continuing to supply power for BMS master control under the condition that the vehicle parks for a long time, goes or charges, make vehicle battery system be in the controlled state all the time.

In concrete implementation, optionally, the monitoring conversion module 110, the main control module 120, the rectification isolation module 150 and the like in the monitoring power distribution system of the vehicle can be installed on the high-voltage box, so that the components can be quickly disassembled and assembled, and the safety, reliability and rationality of the overall design of the monitoring power distribution system are further improved.
