DETAILED DESCRIPTION

[0017] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] Figure 1 This is a flow chart of a battery control method proposed in this application, which is suitable for locking the battery of a vehicle. Specifically, the battery control method can be executed by a battery control device, which can be implemented in the form of software and / or hardware, and the battery control device can be integrated in a vehicle controller.

[0020] like Figure 1 As shown, the battery control method comprises the following steps: S110. In response to the vehicle being in a dormant state and the remaining power of the battery being less than a power threshold, control the battery based on a first control strategy to prevent the battery from running out of power.

[0021] The remaining power of the battery can be characterized by SOC (State Of Charge). For example, when the vehicle is in a dormant state and the SOC of the battery is less than 10%, the battery is controlled based on the first control strategy to prevent the battery from running out of power.

[0022] Specifically, controlling the battery based on the first control strategy may be controlling the vehicle to charge the battery, or controlling the output terminal of the battery to be disconnected to lock the power of the battery and prevent the battery from running out of power.

[0023] In some embodiments, the control of the battery based on the first control strategy includes: continuously sending a network message for waking up the entire vehicle until the continuous sending time reaches a preset threshold; detecting whether the vehicle is on high voltage; in response to detecting that the vehicle is not on high voltage, controlling the output terminal of the battery to disconnect. For example, continuously sending a network message for waking up the entire vehicle for three minutes to try to wake up the entire vehicle and improve the wake-up rate of the entire vehicle. After three minutes, detect whether the vehicle is on high voltage. If the vehicle is not on high voltage, the vehicle cannot charge the battery. If the battery continues to use electricity, it may cause the battery to run out of power. At this time, in order to prevent the battery from running out of power, the output terminal of the battery is controlled to disconnect. If it is detected that the vehicle is on high voltage, it is determined that the vehicle can charge the battery. At this time, the output terminal of the battery is no longer controlled to disconnect.

[0024] Optionally, when detecting whether the vehicle is on high voltage, it can be achieved in the following way: if the main positive and main auxiliary relays of the BMS (Battery Management System) are in the open state, it is determined that the vehicle is not on high voltage; if the main positive and main auxiliary relays of the BMS are in the closed state, it is determined that the vehicle is on high voltage.

[0025] Furthermore, the control of disconnecting the output end of the storage battery includes: sending a power-off signal to the set network segment; in response to the set network segment going into sleep mode, controlling the output end of the storage battery to disconnect; in response to the set network segment not going into sleep mode within a preset time period, controlling the output end of the storage battery to disconnect. That is, if the set network segment can go into sleep mode normally, then after the set network segment goes into sleep mode, the output end of the storage battery is controlled to disconnect; if the set network segment cannot go into sleep mode all the time, then after a certain period of time, the output end of the storage battery is controlled to disconnect.

[0026] In some embodiments, the control of the battery based on the first control strategy includes: sending a network message for waking up the whole vehicle; starting timing in response to detecting that the whole vehicle enters the awake state; and controlling the output end of the battery to disconnect in response to the timing duration being less than a preset threshold and detecting that the vehicle is not on high voltage. That is, after waking up the whole vehicle, if it is detected that the vehicle is on high voltage during this period, no power-off signal is sent, that is, the output end of the battery is not controlled to be disconnected; if it is detected that the vehicle is not on high voltage during this period, a power-off signal is sent to control the output end of the battery to disconnect.

[0027] Exemplarily, after waking up the whole vehicle, wait for 3 minutes. If the main positive and main auxiliary relays of the BMS are in a closed state during this period, it means that the high voltage of the whole vehicle has been raised and the battery can be continuously replenished. In this case, no power-off command is sent, and there is no need to disconnect the virtual battery output terminal. If within 3 minutes after waking up the whole vehicle, it is detected that the main positive and main auxiliary relays of the BMS of the whole vehicle are in an open state, it means that the high voltage of the whole vehicle has not been raised and the high-voltage battery cannot replenish the battery. In this case, a power-off command is sent. If the main positive and main auxiliary relays of the BMS are detected to be closed before the network segment goes to sleep, it is determined that the high voltage of the whole vehicle has been raised and the high-voltage battery can continue to replenish the battery. In this case, a power-off command is sent, that is, there is no need to disconnect the battery output terminal. If the network segment cannot sleep after receiving the power-off signal, the battery output terminal is disconnected after 1 minute of timing to fully ensure the battery power.

[0028] S120: In response to the vehicle being in an ignition-off state for a duration greater than a duration threshold and the remaining power of the battery being greater than a power threshold, controlling the battery based on a second control strategy to avoid power depletion of the battery.

[0029] In some embodiments, the controlling the battery based on the second control strategy includes: sending a network message for waking up the entire vehicle; sending a power-off signal to a set network segment; and controlling the output end of the battery to disconnect in response to the set network segment going into sleep mode.

[0030] Specifically, when it is detected that the battery SOC ≥ 10% and the vehicle has not been started for 5 days, it is considered that the vehicle has been parked for a long time. In order to protect the battery power, the entire vehicle will be awakened and a power-off command will be sent through the set network segment to disconnect the low-voltage battery output after the set network segment goes into sleep.

[0031] Furthermore, after the output end of the control battery is disconnected, the method further comprises: Send a battery output disconnection reminder to the associated user of the vehicle. Specifically, if it is detected that the battery output has been disconnected, TBOX reports the battery output disconnection to the car cloud, and sends a text message to the user through the car cloud, prompting the user: "The battery voltage of the entire vehicle has been disconnected. You can press the back door micro switch for 5-30 seconds to reconnect the power supply and use the vehicle normally."

[0032] Furthermore, after the output end of the control battery is disconnected, it also includes: in response to detecting that the output end of the battery is closed, continuously sending network messages for waking up the whole vehicle, and detecting whether the vehicle is on high voltage; in response to detecting that the vehicle is not on high voltage, stopping sending network messages for waking up the whole vehicle, and sending a power-off signal to the set network segment; in response to the set network segment being dormant, the output end of the control battery is disconnected again. That is, after the output end of the low-voltage battery is disconnected, if the owner needs to use the vehicle, the low-voltage battery output end can be controlled to close by long pressing the micro-control switch. When the battery output end is detected to be closed, the whole vehicle network is awakened for 3 minutes, and the power-off command is monitored at the same time. If the main positive and main auxiliary relays of the BMS are detected to be in the open state, it is determined that the vehicle cannot be on high voltage. At this time, the battery power-off command is sent, and the network is no longer awakened. After waiting for the set network segment to sleep, the battery output end is disconnected again. If the VCU detects that the main positive and main auxiliary relays of the BMS are in a closed state, it is determined that the high voltage has been increased and the high voltage battery can continue to replenish the battery. The VCU then sends a power-off command. At this time, there is no need to disconnect the battery output terminal and the vehicle can be used normally.

[0033] The battery control method disclosed in the embodiment of the present invention controls the battery based on the first control strategy to avoid the battery running out of power when the vehicle is detected to be in a dormant state and the remaining power of the battery is less than the power threshold; when the vehicle is parked for a long time, if the remaining power of the battery is greater than the power threshold, the battery is controlled based on the second control strategy to avoid the battery running out of power. The battery power can be well preserved when the vehicle has not been used for a long time or the battery power is low, avoiding the trouble of secondary use of the vehicle due to over-discharge of the battery; after the battery is powered off, a friendly prompt can be given to the user to increase the user's perception, thereby improving the user's experience.

[0034] Further, optimize the system design: The present invention avoids the use of a large number of physical lines by designing a network sleep wake-up mechanism, reduces the complexity and cost of the system, and also improves the reliability of the system. Improve wake-up efficiency: The present invention adopts a network wake-up method. Even in the case of a busy network or network failure, a certain retry mechanism can be set to improve the success rate of wake-up, thereby ensuring the normal operation of the system. Effectively manage the power supply: The present invention sets the SOC threshold of the battery. When the SOC of the battery is lower than a certain value, the entire vehicle is woken up through the network, and the network wake-up is maintained for a certain period of time. This can effectively manage the output of the battery, avoid over-discharge of the battery, and extend its service life. Intelligent power-off protection: After the LBMS network segment goes into sleep, the present invention will disconnect the battery output terminal to protect the battery. At the same time, if the power-off signal is not received within a certain period of time, the battery output terminal will not be disconnected. This can further protect the battery while ensuring the normal operation of the system. User-friendly: After the battery output terminal is disconnected, the present invention will send a text message to the user through the car cloud to inform the user: "The normal battery voltage has been disconnected. You can reconnect the power supply by pressing the back door micro switch for 5-30s." This can facilitate users to handle it in time and improve user experience.

[0035] In some optional embodiments, refer to Figure 2 A schematic diagram of a hardware architecture involved in battery control is shown, which includes: a vehicle controller VCU-210, an on-board communication terminal TBOX-220, a battery management system BMS-230 responsible for managing high-voltage batteries, and a battery management system LBMS-240 responsible for managing low-voltage batteries. The VCU and TBOX, the VCU and BMS, and the VCU and LBMS all communicate through the CAN bus. Specifically, the VCU is the executor of the battery control method proposed in the embodiment of the present application, responsible for detecting the vehicle status, obtaining the remaining battery power from the LBMS, and sending a power-off instruction to the LBMS, detecting whether the vehicle is on high voltage from the BMS, and sending a battery power-off reminder to the user through the TBOX.

[0036] In some embodiments, an exception handling mechanism is set. Specifically, if the CAN segment communication between the VCU and the BMS is lost for 10 times, the VCU uses the data before the loss. If the CAN segment communication between the VCU and the BMS is lost for 10 times, the VCU controls the vehicle to power off, and determines whether to send a power-off command based on whether the remaining power of the low-voltage battery is less than 10%. Similarly, if the CAN segment communication between the VCU and the LBMS is lost for 10 times, the VCU uses the data before the loss. If the CAN segment communication between the VCU and the LBMS is lost for 10 times, the LBMS determines whether to send a power-off command based on whether the remaining power is less than 10%. If the CAN segment communication between the VCU and the TBOX is lost for 10 times, the VCU uses the data before the loss. If the CAN segment communication between the VCU and the TBOX is lost for 10 times, no processing is performed to avoid causing trouble to the user.

[0037] In some embodiments, reference is made to Figure 3 The flowchart of another battery control method shown in the figure specifically includes the following steps: S310, when the vehicle is stationary and in a dormant state, and the remaining battery power is less than 10%, wake up the vehicle. S320, determine whether the high voltage of the vehicle is powered on. If not, execute step S330, otherwise, do not issue a power-off command, and the battery output terminal remains connected. S330, issue a power-off command, and the battery output terminal is disconnected.

[0039] In some embodiments, the first control module 410 includes a sending unit for continuously sending network messages for waking up the entire vehicle until the continuous sending duration reaches a preset threshold; a detection unit for detecting whether the vehicle is on high voltage; and a control unit for controlling the output end of the battery to disconnect in response to detecting that the vehicle is not on high voltage.

[0040] Furthermore, the control unit is specifically used to: send a power-off signal to a set network segment; in response to the set network segment going into sleep mode, control the output end of the battery to disconnect; in response to the set network segment not going into sleep mode within a preset time period, control the output end of the battery to disconnect.

[0041] In some embodiments, the first control module 410 is specifically used to send a network message for waking up the entire vehicle; in response to detecting that the entire vehicle enters a wake-up state, start timing; in response to the timing duration being less than a preset threshold and detecting that the vehicle is not on high voltage, control the output end of the battery to disconnect.

[0042] In some implementations, the second control module 420 is specifically configured to send a network message for waking up the entire vehicle; send a power-off signal to a set network segment; and control the output terminal of the battery to disconnect in response to the set network segment going into sleep mode.

[0043] In some embodiments, a sending module is further included, which is used to send a battery output terminal disconnection reminder to an associated user of the vehicle after the output terminal of the battery is controlled to be disconnected.

[0044] In some embodiments, it also includes: a third control module, which is used to, after the output terminal of the control battery is disconnected, in response to detecting that the output terminal of the battery is closed, continuously send network messages for waking up the entire vehicle, and at the same time detect whether the vehicle is on high voltage; in response to detecting that the vehicle is not on high voltage, stop sending network messages for waking up the entire vehicle and send a power-off signal to the set network segment; in response to the set network segment being dormant, control the output terminal of the battery to disconnect again.
