DETAILED DESCRIPTION

[0018] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0019] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0020] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0021] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0022] In order to improve the flexibility of external discharge in the camping mode and thus improve the user experience, an embodiment of the present invention provides a vehicle external discharge method. Figure 1 The flowchart of a vehicle external discharge method provided by an embodiment of the present invention. Figure 1 As shown in , the method includes: Step 101, in response to an external discharge instruction, obtain external discharge custom configuration information. The external discharge custom configuration information includes a custom discharge threshold.

[0023] Among them, the central control screen or control console of the target vehicle may be provided with an option or button for external discharge. When the user controls the target vehicle to switch to camping mode, the external discharge custom configuration information may be set. When the user confirms that the external discharge custom configuration information is correct, the corresponding confirmation button or confirmation option may be pressed, and the target vehicle receives the external discharge instruction. The custom discharge threshold in the external discharge custom configuration information is the minimum power of the power battery for external discharge. When the remaining power of the power battery is less than the custom discharge threshold, the power battery will stop discharging.

[0024] Optionally, after the user controls the target vehicle to switch to camping mode, the default value of the external discharge custom configuration information can be displayed first, and the user can modify the default value according to actual needs. If the user does not modify the default value, the default value is used as the custom discharge threshold. For example, when the user presses the option to switch to camping mode, the relevant interface of the camping mode is displayed, which includes a setting window or setting interface for the external discharge custom configuration information. The setting window or setting interface includes a setting option for the custom discharge threshold, and there is a default value (for example, the default value is 10%). If the user directly chooses to confirm, the custom discharge threshold received by the target vehicle is the default value. If the user changes the custom discharge threshold in the setting interface (for example, changes the default value of 10% to 15%), the custom discharge threshold received by the target vehicle is the changed 15%.

[0025] Step 102, obtaining the status information of the power extraction gun and the vehicle status information of the target vehicle.

[0026] Among them, after switching to the camping mode, the target vehicle needs to discharge electricity to the outside to power various electrical appliances. Therefore, the user needs to connect the power gun to the target vehicle, and the target vehicle determines the connection status of the power gun by detecting the power gun status information.

[0027] The vehicle status information may include ignition key gear position information, vehicle readiness status information, vehicle gear position status information, and vehicle speed information.

[0028] Step 103, determining whether the vehicle status information and the battery gun status information both meet the external discharge conditions.

[0029] Among them, judging whether the state information of the power gun meets the external discharge condition may include: Determine whether the power gun is in a discharge connection state based on the power gun status information. Specifically, when the user switches the target vehicle to camping mode, the power gun needs to be plugged in. If the target vehicle is in a non-high-voltage power-on state at this time, the user needs to first insert the power gun into the target vehicle. The other end of the power gun can be connected to a low-voltage electrical appliance (such as an induction cooker or a light, etc.). At this time, the charging and discharging system assembly of the target vehicle detects the signal of the power gun being inserted, and sends a signal to the CAN bus of the target vehicle that the power gun is connected in a semi-connected state. After that, the user presses the start switch on the power gun, and the charging and discharging system assembly detects the resistance value and sends a signal to the CAN bus that the power gun is connected in a discharge connection state. When the target vehicle detects that the power gun is in a discharge connection state through the CAN bus, it is determined that the power gun status information meets the external discharge conditions.

[0030] Optionally, if the target vehicle is in high voltage power-on state before the user plugs in the power gun, the user needs to press the start switch on the power gun first, and then plug the power gun into the target vehicle. The charge and discharge system assembly detects the resistance value and directly sends to the CAN bus that the power gun is connected in a discharge connection state.

[0031] In some embodiments, determining whether the vehicle status information satisfies the external discharge condition may include: determining whether the ignition key gear is in the ON gear according to the ignition key gear information. Determining whether the target vehicle is currently in the ready state (i.e., READY state) according to the vehicle ready state information. Determining whether the gear of the target vehicle is the parking gear (P gear) according to the vehicle gear state information. Determining whether the target vehicle is in a parking state according to the vehicle speed information. Determining whether the remaining power of the power battery is greater than a custom discharge threshold. And, determining whether the self-test state of the target vehicle is normal.

[0032] Specifically, when the ignition key position is ON, the target vehicle is currently in a non-ready state (if it is in a ready state, it will revert to a high-voltage power-on state from the ready state), the target vehicle is in the parking position, the vehicle speed is less than 2km / h, the remaining power of the power battery is greater than the custom discharge threshold and the self-test is normal, it is determined that the vehicle status information meets the external discharge conditions.

[0033] Step 104: If the external discharge condition is met, the power battery is controlled to discharge externally through the power extraction gun.

[0034] Among them, the power battery is connected to the vehicle power supply circuit only when it is in the high-voltage power-on state. Therefore, before the power battery discharges to the outside, it is necessary to determine whether the target vehicle is in the high-voltage power-on state. If the target vehicle is not in the high-voltage power-on state, it is necessary to control the target vehicle to switch to the high-voltage power-on state first, and then control the power battery to discharge to the outside.

[0035] Step 105: When an external discharge termination condition is detected, the power battery is controlled to stop external discharge. The external discharge termination condition at least includes that the remaining power of the power battery is less than a custom discharge threshold.

[0036] Among them, the termination condition of external discharge may include multiple judgment conditions, and when any judgment condition is met, the control thing battery stops external discharge. Specifically, in addition to detecting that the remaining power of the power battery is less than the custom discharge threshold, the judgment conditions may also include: vehicle gear change, ignition key gear change, power gun connection status change, or target vehicle failure. Among them, the vehicle gear change specifically refers to the vehicle gear changing from P gear to other gears. The ignition key gear change specifically refers to the ignition key changing from ON gear to other gears. The connection state of the power gun changes from the discharge connection state to the semi-connected state. The high-voltage power-on state of the target vehicle changes to the non-high-voltage power-on state.

[0037] The target vehicle failure may specifically include: the target vehicle high voltage power failure, the charging and discharging system assembly state is a fault state. The vehicle mode control request is a maintenance mode. The charging connection preparation state of the power battery is a charging access state. The power battery temperature is abnormal, the power battery voltage is abnormal, the target vehicle short circuit is abnormal, etc. When the target vehicle fails, the cause of the failure of the target vehicle can be determined, and corresponding safety measures can be executed according to the cause of the failure. For example, when the temperature of the power battery is too high or the voltage is abnormal, the power battery is controlled to stop discharging and the heat dissipation measures for the power battery are started. For another example, when a short circuit is detected, the discharge circuit is immediately cut off to ensure the safety of the user and the target vehicle. For another example, when the discharge current is detected to exceed the set threshold, the external discharge power of the power battery is reduced, and in serious cases, the power battery is stopped from discharging.

[0038] In some embodiments, during the process of the power battery discharging, discharge parameters can also be obtained and displayed so that the user can accurately know the discharge status. Specifically, the discharge parameters may include the remaining power of the power battery, discharge voltage, discharge current, discharge power, and discharge time.

[0039] In some embodiments, for hybrid vehicles, their built-in range extenders can charge the power battery by converting oil into electricity. Therefore, when the target vehicle is a hybrid vehicle, the camping mode can provide an automatic charging function. The automatic charging function specifically refers to: when the remaining power of the power battery is low, the engine and the range extender are automatically controlled to start to recharge the power battery. Specifically, an automatic charging status bit can be added to the external discharge custom configuration information. When the automatic charging status bit is on, it means that the user has turned on the automatic charging function. During the automatic discharge process, it can be determined whether the remaining power of the power battery is less than the first threshold. If the remaining power of the power battery is less than the first threshold, the generator is controlled to recharge the power battery. Among them, the first threshold is greater than or equal to the custom discharge threshold.
