[0036] In order to make the above and other features and advantages of the present application more clear, the present application is further described below in conjunction with the accompanying drawings. It should be understood that the specific embodiments given herein are for the purpose of explaining to those skilled in the art and are only exemplary and not restrictive.

[0037] In the following description, many specific details are set forth to provide a thorough understanding of the present application. However, it is apparent to those skilled in the art that specific details need not be adopted to practice the present application. In other cases, well-known steps or operations are not described in detail to avoid blurring the present application.

[0038] The present application embodiment provides a mobile power supply control system for an electric vehicle, such as Figure 1 The figure shows the framework of the mobile power control system of the electric vehicle, and the system includes: a vehicle controller 10, a mobile power assembly 11, and a power distributor 12. The vehicle controller 10 is electrically connected to the mobile power assembly 11 and the power distributor 12, and the mobile power assembly 11 is electrically connected to the power distributor 12, and a first relay k1 is provided in the connection line. By controlling the on / off of k1, the mobile power supply is turned on / off to supply power to the vehicle. Figure 1As shown in , the mobile power supply assembly 11 includes a mobile power supply auxiliary device (HRMU) and a mobile power supply. In one embodiment, the mobile power supply auxiliary device can be used to detect the status information of the mobile power supply, and the status information includes at least one of the following: voltage, temperature, remaining power and fault status. The mobile power supply auxiliary device is also used to communicate with the vehicle controller 10, including receiving the mobile power supply working instruction and the mobile power supply shutdown instruction sent by the vehicle controller 10, and sending the mobile power supply shutdown request or status abnormality message to the vehicle controller 10, and sending the status information of the mobile power supply, etc. The mobile power supply auxiliary device is also used to drive the relay k1 to close or open according to the received mobile power supply working instruction or mobile power supply shutdown instruction, so as to realize the connection or disconnection between the mobile power supply and the power distributor 12, and then realize the opening of the mobile power supply to power the whole vehicle or the stopping of the mobile power supply to power the whole vehicle; and the mobile power supply auxiliary device is also used to control the connection between the mobile power supply and the boost module according to the received mobile power supply working instruction.

[0039] The structural diagram of an embodiment of the mobile power supply control system of an electric vehicle is as follows: Figure 2 As shown in the figure, VCU is the vehicle controller 10, the vehicle power bank is the mobile power component 11, and the PDU is the power distributor 12. The VCU is connected to the vehicle power bank through the CAN bus, and a first relay k1 is provided in the line connecting the vehicle power bank and the PDU. HRMU is a mobile power auxiliary device, and a second relay k2 (not shown in the figure) is integrated inside the HRMU, and the k2 can be a high-side drive relay. After the VCU wakes up the vehicle power bank through the KL15 hard line, the HRMU initializes the detection of the mobile power status information and sends it to the VCU. After the VCU determines that the mobile power meets the specified working conditions based on the status information, it sends a mobile power work instruction to the HRMU. After receiving the mobile power work instruction sent by the VCU, the HRMU drives k2 to close, thereby controlling the connection between the mobile power and the boost module. Further, the HRMU drives k1 to close, so that the mobile power is connected to the PDU, so that the mobile power supplies the whole vehicle.

[0040] like Figure 2 As shown in, in one embodiment, the mobile power supply assembly may further include a boost module, which may be a DC / DC boost module, which may be arranged inside the mobile power supply assembly and connected to the connection line between the mobile power supply and the PDU, and is used to boost the voltage output by the mobile power supply to a voltage value matching the voltage platform of the vehicle main battery, thereby saving the number of mobile power supply groups.

[0041] In addition to being connected to the VCU and the vehicle-mounted power bank, the PDU is also connected to the EDU, the vehicle-mounted main battery, and various power-demanding devices, and is used to select one of the vehicle-mounted power bank and the vehicle-mounted main battery to power various power-demanding devices according to the control of the VCU.

[0042] The electric vehicle mobile power supply control method provided in the embodiment of the present application can be executed by the electric vehicle mobile power supply control device or the electric vehicle mobile power supply control system provided in the embodiment of the present application, and the device can be configured in an electronic device.

[0043] like Figure 3 The flowchart of the electric vehicle mobile power supply control method according to one embodiment of the present application is shown, and the method comprises the following steps:

[0044] S310, after determining that the electric vehicle meets the conditions for triggering the use of the mobile power supply, waking up the mobile power supply so that the mobile power supply detects its own status information;

[0045] In one embodiment, the electric vehicle mobile power supply control method can be applied to a vehicle control unit (VCU).

[0046] In order to realize intelligent control of the battery power of an electric vehicle, the embodiment of the present application can detect in real time by the vehicle controller whether the current electric vehicle meets the conditions for triggering the use of a mobile power supply.

[0047] In one embodiment, the determining that the electric vehicle meets the condition for triggering the use of the mobile power supply includes any one of the following:

[0048] 1) Upon receiving a request for using a mobile power source from a user, determining that the electric vehicle meets the conditions for triggering the use of the mobile power source;

[0049] That is, in one embodiment of the present application, the vehicle controller can receive a request from a user to use a mobile power supply, and after receiving the request, it is determined that the electric vehicle meets the conditions for triggering the use of a mobile power supply. For example, a hardware trigger button or a software trigger button can be provided to the user, through which the user can choose to use a mobile power supply to power the vehicle. For example, when driving long distances, the user can choose to use a mobile power supply to power the vehicle first, in order to extend the range of the electric vehicle. At this time, the user can use the hardware trigger button or the software trigger button to select a mobile power supply to power the vehicle.

[0050] 2) When it is detected that the power level of the vehicle's main battery is lower than a set value and is in a non-charging mode, it is determined that the electric vehicle meets the conditions for triggering the use of a mobile power supply.

[0051] In one embodiment of the present application, the vehicle controller can detect the power level of the vehicle main battery in real time. When it is detected that the power level of the vehicle main battery is lower than a set value and the vehicle main battery is in a non-charging mode, it is determined that the electric vehicle meets the conditions for triggering the use of a mobile power supply. That is, the embodiment of the present application automatically monitors the power level of the vehicle main battery, and automatically triggers switching to a mobile power supply to power the vehicle when the power level is lower than a set value.

[0052] In one embodiment, the set value can be set as needed, for example, the value range can be 5% to 10%. The value represents the ratio of the current power to the total power.

[0053] In one embodiment, the mobile power supply can be awakened by the KL15 hard line. After the mobile power supply is awakened, the mobile power supply auxiliary device initializes and detects the mobile power supply's own status information, and the status information may include the voltage, temperature, power and fault status of the mobile power supply.

[0054] S320, obtaining status information of the mobile power supply, and determining based on the status information that the mobile power supply meets specified working conditions, sending a mobile power supply working instruction to the mobile power supply auxiliary device, so that the mobile power supply auxiliary device drives the first relay to close, so that the mobile power supply supplies power to the entire vehicle; wherein the first relay is arranged in a line connecting the mobile power supply and the vehicle power distributor.

[0055] In one embodiment, the vehicle controller can receive the status information of the mobile power supply detected and sent by the mobile power supply auxiliary device after waking up the mobile power supply, so as to determine whether the current mobile power supply is powering the whole vehicle according to the status information. In one embodiment, by comparing the status information with the specified working conditions, it is determined whether the mobile power supply can power the whole vehicle, including judging whether the current remaining power of the mobile power supply is greater than the specified power threshold (the specified power threshold can be set as needed, for example, the specified power threshold value range can be 5% to 10%), and judging whether the mobile power supply is faulty according to the fault status information. When all the judgment results meet the specified working conditions, it is determined that the mobile power supply can power the whole vehicle, and a mobile power supply working instruction can be sent to the mobile power supply auxiliary device.

[0056] It is understandable that, in the process of determining whether the mobile power source meets the specified working conditions according to the mobile power source status information, multiple determination conditions may be set as required, and multiple conditions may be determined at the same time.

[0057] In one embodiment, the mobile power auxiliary device integrates a second relay k2. After receiving the mobile power working instruction sent by the vehicle controller, it drives k2 to close, controls the mobile power to establish a connection with the boost module, and further drives the first relay k1 to close, so that the mobile power can power the entire vehicle.

[0058] The k1 is arranged in the connection path between the mobile power source and the power distributor. When k1 is closed, the mobile power source is connected to the power distributor. The power distributor can switch the power supply of the whole vehicle from the vehicle main battery to the mobile power source, so that the mobile power source can supply power to the whole vehicle.

[0059] In one embodiment, the mobile power supply for supplying power to the vehicle includes:

[0060] The voltage output by the mobile power source is boosted by a boost module to a voltage value matching the voltage platform of the vehicle-mounted main battery.

[0061] In one embodiment, the k2 relay integrated in the mobile power auxiliary device can be used to control whether the voltage output by the mobile power supply is boosted by the boost module. When the voltage of the mobile power supply does not match the voltage of the vehicle main battery, the mobile power auxiliary device drives k2 to close, so that the voltage output by the mobile power supply is boosted by the boost module to a voltage value that matches the voltage platform of the vehicle main battery.

[0062] The embodiment of the present application can utilize a boost module to boost the voltage output by the mobile power supply to a voltage value that matches the voltage platform of the vehicle main battery, so that mobile power supplies of different numbers can adapt to the voltage requirements of the entire vehicle, thereby reducing the number of mobile power supply groups and effectively reducing the cost of the mobile power supply.

[0063] It is understandable that if the voltage output by the mobile power source matches the voltage platform of the vehicle main battery, the mobile power source can directly power the entire vehicle without passing through the boost module. Figure 2 The circuit structure shown in is only an example and does not limit the present application.

[0064] In one embodiment, during the process of the mobile power supply supplying power to the whole vehicle, the method further includes:

[0065] The real-time status information of the mobile power source detected by the mobile power source auxiliary device is received, and it is determined whether to send a mobile power source shut-down instruction according to the real-time status information.

[0066] In this embodiment, the mobile power auxiliary device can detect the real-time status information of the mobile power in real time and send it to the vehicle controller, so that the vehicle controller can determine whether to send a mobile power shutdown instruction based on the real-time status information. The real-time status information includes at least one of the following: remaining power, fault status; it can be understood that the real-time status information is not limited to this, and can also include other relevant information of the mobile power, such as voltage, temperature and other parameters. The determination of whether to send a mobile power shutdown instruction based on the real-time status information includes:

[0067] When the remaining power is lower than the specified power threshold or the mobile power state is judged to be abnormal according to the fault state information, a mobile power shutdown instruction is sent to the mobile power auxiliary device, so that the mobile power auxiliary device disconnects the first relay and stops the mobile power supply to the entire vehicle.

[0068] It is understandable that when the vehicle is powered by a mobile power supply, if the mobile power supply is too low or fails, it will not be able to power the vehicle, causing the vehicle to be unable to drive. To avoid this phenomenon, the embodiment of the present application can detect the status of the mobile power supply in real time by the mobile power supply auxiliary device, and send the real-time status information to the vehicle controller, and the vehicle controller determines whether to stop the mobile power supply from supplying power to the vehicle based on the acquired real-time status information. For example, when the remaining power of the mobile power supply is higher than the specified power threshold and the real-time status information is detected to be normal, the mobile power supply is kept to supply power to the vehicle; when the remaining power of the mobile power supply is lower than the specified power threshold or the real-time status information is detected to be abnormal, the vehicle controller sends a mobile power shutdown instruction to the mobile power supply auxiliary device, so that the mobile power supply auxiliary device disconnects the first relay and the power distributor restores the vehicle main battery to supply power to the vehicle.

[0069] In another embodiment of the present application, during the process of the mobile power supply supplying power to the whole vehicle, the method further includes:

[0070] After receiving the mobile power off request or abnormal status message sent by the mobile power auxiliary device, a mobile power off instruction is sent to the mobile power auxiliary device to make the mobile power auxiliary device disconnect the first relay and stop the mobile power supply to the whole vehicle.

[0071] In the embodiment of the present application, when the vehicle is powered by a mobile power supply, the mobile power auxiliary device can detect the real-time status information of the mobile power supply in real time, and determine whether to send a mobile power shutdown request or a status abnormality message to the vehicle controller based on the acquired real-time status information. For example, when the remaining power of the mobile power supply is higher than the specified power threshold and the real-time status information is detected to be normal, the mobile power supply is kept to supply power to the vehicle; when the remaining power of the mobile power supply is detected to be lower than the specified power threshold, a mobile power shutdown request is sent to the vehicle controller; or when the mobile battery is judged to be faulty based on the real-time status information, a status abnormality message is sent to the vehicle controller. The vehicle controller sends a mobile power shutdown instruction to the mobile power auxiliary device based on the received mobile power shutdown request or status abnormality message, so that the mobile power auxiliary device disconnects the first relay and stops the mobile power supply from supplying power to the vehicle, ensuring that the vehicle can obtain normal power supply in a timely manner.

[0072] In another embodiment of the present application, during the process of the mobile power supply supplying power to the entire vehicle, the method further includes:

[0073] The vehicle controller receives a request from the user to turn off the mobile power supply, and after receiving the request from the user to turn off the mobile power supply, sends a mobile power supply turn-off instruction to the mobile power supply auxiliary device, so that the mobile power supply auxiliary device disconnects the first relay, and the power distributor can restore the vehicle main battery to power the vehicle. That is, the embodiment of the present application can provide the user with a turn-off button for the user to choose to turn off the mobile power supply to power the vehicle.

[0074] The electric vehicle mobile power supply control method described in the embodiment of the present application can automatically detect whether the conditions for triggering the use of the mobile power supply are met, wake up the mobile power supply after determining that the conditions for triggering the use of the mobile power supply are met, and send a mobile power supply working instruction based on the mobile power supply status information to determine that the mobile power supply can be used for normal power supply, so that the relay between the mobile power supply and the vehicle power distributor is closed, and the mobile power supply can power the entire vehicle. The present application realizes the intelligent control of the mobile power supply without human participation, and can avoid the phenomenon that the vehicle cannot be driven due to the owner's failure to pay attention to the remaining power in time.

[0075] The present application also provides a mobile power supply control device for electric vehicles, which is applied to a vehicle controller, such as Figure 4 The device structure block diagram is shown, and the electric vehicle mobile power supply control device 400 includes:

[0076] A wake-up unit 410 is used to wake up the mobile power supply after determining that the electric vehicle meets the conditions for triggering the use of the mobile power supply, so that the mobile power supply initializes and detects its own status information;

[0077] In one embodiment, determining that the electric vehicle meets the conditions for triggering the use of a mobile power supply includes: upon receiving a request for use of a mobile power supply from a user, determining that the electric vehicle meets the conditions for triggering the use of a mobile power supply; or upon detecting that the power level of the vehicle's main battery is lower than a set value and is in a non-charging mode, determining that the electric vehicle meets the conditions for triggering the use of a mobile power supply.

[0078] In one embodiment, the set value can be set as needed, for example, the value range can be 5% to 10%. The value represents the ratio of the current power to the total power.

[0079] In one embodiment, the wake-up unit 410 can wake up the mobile power supply through the KL15 hard line. After the mobile power supply is awakened, the mobile power supply auxiliary device initializes and detects the mobile power supply's own status information. The status information may include the voltage, temperature, power and fault status of the mobile power supply.

[0080] The mobile power supply working instruction sending unit 420 is used to obtain the status information of the mobile power supply, and to determine based on the status information that the mobile power supply meets the specified working conditions, and then send a mobile power supply working instruction to the mobile power supply auxiliary device, so that the mobile power supply auxiliary device drives the first relay to close, so that the mobile power supply supplies power to the entire vehicle; wherein the first relay is set in a line connecting the mobile power supply and the vehicle power distributor.

[0081] In one embodiment, the mobile power supply working instruction sending unit 420 can receive the status information of the mobile power supply detected and sent by the mobile power supply auxiliary device after waking up the mobile power supply, so as to determine whether the current mobile power supply is supplying power to the whole vehicle according to the status information.

[0082] In one embodiment, the mobile power supply working instruction sending unit 420 receives real-time status information of the mobile power supply detected by the mobile power supply auxiliary device, and determines whether to send a mobile power supply shutdown instruction based on the real-time status information; or in another embodiment, after receiving a mobile power supply shutdown request or a status abnormality message sent by the mobile power supply auxiliary device, the vehicle controller sends a mobile power supply shutdown instruction to the mobile power supply auxiliary device, so that the mobile power supply auxiliary device disconnects the first relay and stops the mobile power supply from supplying power to the vehicle.

[0083] In one embodiment, the voltage output by the mobile power source is boosted by the boost module to a voltage value matching the voltage platform of the vehicle main battery and then output to the power distributor.

[0084] In summary, the mobile power control device for electric vehicles described in the embodiment of the present application can automatically detect whether the conditions for triggering the use of the mobile power are met, wake up the mobile power after determining that the conditions for triggering the use of the mobile power are met, and determine that the mobile power can be used for normal power supply according to the mobile power status information, and send a mobile power work instruction to close the relay between the mobile power and the vehicle power distributor, so that the mobile power can power the entire vehicle. The present application realizes the intelligent control of the mobile power without human participation, which can avoid the phenomenon that the vehicle cannot be driven due to the owner's failure to pay attention to the remaining power in time.
