DETAILED DESCRIPTION

[0039] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0040] Next, the application scenario or system architecture of the embodiments of the present application will be described. Referring to Figure 1 shown, generally, the system for activating the electrolytic capacitor of the on-board charger includes IBS 101, battery 102, VCU 103, DCDC / OBC 104, power battery 105 and fast / slow charging socket 106.

[0041] Among them, IBS 101 is used to monitor the power of battery 102, when the power of battery 102 is lower than a certain power threshold, IBS 101 wakes up VCU 103 and sends a charging request of battery 102. Wherein, the certain power threshold can be set by the person skilled in the art according to the actual situation, and the present application does not make specific limitation.

[0042] VCU 103, configured to receive a charging request of the IBS 101, control the vehicle to be powered on, start the DCDC 104 to charge the battery 102, detect a connection state of a fast charging port charging gun, and control the vehicle to start or stop fast charging; identify a vehicle mode and send the vehicle mode to a CAN (Controller Area Network) bus.

[0043] The DCDC / OBC 104, wherein the DCDC 104 charges the battery 102 in response to an instruction of the VCU 103; the OBC 104 charges the power battery 105 in response to an instruction of the VCU 103, inverts and discharges externally, and identifies a signal of the vehicle to control activation and stop of the electrolytic capacitor strategy.

[0044] The power battery 105, configured to store and release energy.

[0045] The fast / slow charging socket 106, wherein the fast charging socket is connected to a fast charging pile charging gun to charge the power battery 105, and the slow charging socket is connected to a slow charging pile charging gun to charge the power battery 105.

[0046] Specifically, in the embodiment of the present application, after the vehicle is powered on, the VCU 103 identifies and judges a charging request of the vehicle, and sends the charging request to the CAN bus; the OBC 104 receives the charging request and other CAN signals, and judges whether the charging request meets (1) the charging request is a battery intelligent charging request, that is, the vehicle mode is a battery intelligent charging mode; (2) the charging request is a fast charging and no discharge charging request, that is, the vehicle mode is a fast charging mode and the vehicle has no 220 Vac discharge demand; in the two cases, the capacitor activation repair is started; otherwise, the capacitor activation repair is not started, and the vehicle is responded to the instruction.

[0047] Further, after the capacitor activation repair is started, the OBC 104 charges the high-voltage power battery 105 to the electrolytic capacitor by controlling the on-off of the switching tube, charges the voltage between the two ends of the electrolytic capacitor to a certain threshold value, activates and repairs the electrolytic capacitor by applying voltage to the electrolytic capacitor, and stops the capacitor activation repair until the vehicle meets certain power-off conditions. The certain threshold value can be set by a person skilled in the art according to the actual situation, and the present application does not make specific limitations.

[0048] An activation method and device for an electrolytic capacitor of a vehicle-mounted charger are described below with reference to the accompanying drawings. To address the technical problems of strong condition dependency, inability to meet fast charging without discharging, low repair efficiency, poor environmental adaptability, and difficulty in applying to long-term non-use scenarios of a vehicle mentioned in the background, the present application provides an activation method for an electrolytic capacitor of a vehicle-mounted charger. In the method, the vehicle can be powered on in response to a charging request of a vehicle intelligent battery system. When the charging request is a smart battery charging request or a fast charging without discharging request, the voltage of the electrolytic capacitor is charged to a certain threshold to repair the electrolytic capacitor until a certain power-off condition is met. When the charging request is not a smart battery charging request or a fast charging without discharging request, the vehicle is charged based on the charging request until a certain power-off condition is met. The electrolytic capacitor can be automatically activated and repaired without affecting the normal use of the vehicle, delaying battery aging, and prolonging the overall battery pack life. In addition, no additional hardware is required, costs are reduced, user satisfaction is improved, and charging efficiency and energy utilization are improved. Thus, the technical problems of strong condition dependency, inability to meet fast charging without discharging, low repair efficiency, poor environmental adaptability, and difficulty in applying to long-term non-use scenarios of a vehicle in related technologies are solved.

[0049] Specifically, Figure 2 A flowchart of an activation method for an electrolytic capacitor of a vehicle-mounted charger according to an embodiment of the present application is provided.

[0050] As Figure 2 shown, the activation method for an electrolytic capacitor of a vehicle-mounted charger includes the following steps:

[0051] In step S201, the vehicle is powered on in response to a charging request of a vehicle intelligent battery system to determine whether the charging request is a smart battery charging request or a fast charging without discharging request.

[0052] It can be understood that in the present application, the smart battery charging request can be understood as a vehicle mode being a smart battery charging mode, wherein the smart battery charging mode is an advanced charging strategy that automatically adjusts charging parameters by monitoring the battery state dynamically and combining user habits through the built-in intelligent system. The fast charging without discharging request can be understood as a vehicle mode being a fast charging mode and no 220Vac discharging requirement of the vehicle, wherein fast charging can be understood as a charging method that quickly supplements the power with high power (such as power ≥ 15W, etc., which is not limited in the present application). Discharging can be understood as no external discharging of 220Vac during the charging process, etc., which is not limited in the present application.

[0053] As a possible implementation manner, the embodiment of the application can control the vehicle to be powered on in response to the charging request of the vehicle intelligent battery system, and determine whether the charging request is the intelligent battery charging request or the fast charging no-discharge charging request.

[0054] For example, as shown in Figure 1 After the vehicle is woken up by the power-on, the VCU of the embodiment of the application identifies and determines the charging request and sends it to the CAN bus; the OBC receives the charging request and other CAN signals and determines whether the charging request is the intelligent battery charging request or the fast charging no-discharge charging request.

[0055] Optionally, in an embodiment of the application, before responding to the charging request of the vehicle intelligent battery system, the method further includes: receiving the charging request of the vehicle intelligent battery system; obtaining the power of the vehicle battery and detecting whether the power of the battery is less than a preset power threshold; and allowing the response to the charging request in the case that the power of the battery is detected to be less than the preset power threshold.

[0056] It can be understood that, before responding to the charging request of the vehicle intelligent battery system, the embodiment of the application can also detect whether the power of the battery is less than a certain power threshold, and allow the response to the charging request in the case that the power of the battery is less than the certain power threshold. The certain power threshold can be set by a person skilled in the art according to the actual situation, and the application does not make specific limitations.

[0057] In some embodiments, the embodiment of the application can receive the charging request of the vehicle intelligent battery system, and detect whether the power of the battery is less than a certain power threshold, and allow the response to the charging request in the case that the power of the battery is detected to be less than the certain power threshold.

[0058] For example, as shown in Figure 1 After the fast charging pile charging gun is inserted into the fast charging socket, the embodiment of the application sends the charging request to the vehicle VCU through the CAN bus, the VCU is woken up and receives the charging request, and the battery management system is activated to detect the power, and the power of the battery is obtained. When the power of the battery is 18% and is lower than a certain power threshold 20% (the application does not make specific limitations), the response to the charging request is allowed.

[0059] Optionally, in an embodiment of the present application, the determining whether the charging request is the fast charging and no discharging charging request comprises: detecting state information of the vehicle; determining, based on the state information, whether a connection state of a fast charging gun of the vehicle is a connected state and whether a state of a power battery of the vehicle is a storage state; if the connection state of the fast charging gun is the connected state and the state of the power battery is the storage state, determining, according to the connection state of the fast charging gun and the state of the power battery, that the charging request is the fast charging and no discharging charging request; and if the connection state of the fast charging gun is not the connected state or the state of the power battery is not the storage state, determining, according to the connection state of the fast charging gun or the state of the power battery, that the charging request is not the fast charging and no discharging charging request.

[0060] It can be understood that, in the embodiment of the present application, the connection state of the fast charging gun can include, but is not limited to, the connected state and the unconnected state, and the present application does not make specific limitation; wherein the connected state can be understood as that the fast charging gun is connected and the communication is normal, and the present application does not make specific limitation.

[0061] The state of the power battery can include, but is not limited to, the storage state and the release state, and the present application does not make specific limitation; wherein the storage state can be understood as that the power battery has a power lower than a certain power threshold and the parameters such as the battery temperature and the voltage are within a safe range, and has the ability to accept fast charging. The certain power threshold can be set by a person skilled in the art according to the actual situation, and the present application does not make specific limitation.

[0062] In some embodiments, the embodiment of the present application can first detect the state information of the vehicle, and then determine, according to the state information, whether the connection state of the fast charging gun of the vehicle is the connected state and whether the state of the power battery of the vehicle is the storage state.

[0063] Further, when the connection state of the fast charging gun is the connected state and the state of the power battery is the storage state, the embodiment of the present application can determine, according to the connection state of the fast charging gun and the state of the power battery, that the charging request is the fast charging and no discharging charging request.

[0064] When the connection state of the fast charging gun is not the connected state, the embodiment of the present application can determine, according to the connection state of the fast charging gun, that the charging request is not the fast charging and no discharging charging request.

[0065] When the state of the power battery is not the storage state, the embodiment of the present application can determine, according to the state of the power battery, that the charging request is not the fast charging and no discharging charging request.

[0066] For example, in combination with Figure 1As shown, the embodiment of the present application detects the connection state of the fast charging gun and the state of the power battery at the same time. When the connection state of the fast charging gun is the connected state and the state of the power battery is the energy storage state, it is determined that the charging request is the fast charging no discharge charging request.

[0067] Optionally, in an embodiment of the present application, whether the charging request is the storage battery intelligent charging request is determined by judging whether the DCDC is started. If the DCDC is started, the DCDC is controlled to charge the storage battery in the vehicle, so as to determine that the charging request is the storage battery intelligent charging request.

[0068] It can be understood that the embodiment of the present application can determine whether the charging request is the storage battery intelligent charging request by whether the DCDC is started. The DCDC can convert high-voltage direct current (such as 400V, etc., which is not limited in the present application) of the power battery into 12V direct current to charge the 12V storage battery.

[0069] Further, the embodiment of the present application can start the DCDC when the voltage of the 12V storage battery is lower than a certain power threshold.

[0070] In some embodiments, the embodiment of the present application can determine whether the DCDC is started, and when the DCDC is started, the DCDC is controlled to charge the storage battery in the vehicle, and it is determined that the charging request is the storage battery intelligent charging request.

[0071] For example, in combination with Figure 1 As shown, the embodiment of the present application can start the DCDC when the voltage of the 12V storage battery is lower than a certain power threshold, such as 12.5V. The VCU sends the storage battery intelligent charging request, and controls the DCDC to start charging the storage battery. The VCU displays "storage battery charging" through the instrument panel, and updates the charging progress in real time.

[0072] In step S202, if the charging request is the storage battery intelligent charging request or the fast charging no discharge charging request, the voltage of the electrolytic capacitor is charged to a preset threshold to repair the electrolytic capacitor until the vehicle meets the preset power-off condition.

[0073] In some embodiments, the embodiment of the present application can charge the voltage of the electrolytic capacitor to a certain threshold when the charging request is the storage battery intelligent charging request, so as to repair the electrolytic capacitor until the vehicle meets a certain power-off condition.

[0074] In some embodiments, the embodiment of the present application can charge the voltage of the electrolytic capacitor to a certain threshold when the charging request is the fast charging no discharge charging request, so as to repair the electrolytic capacitor until the vehicle meets a certain power-off condition.

[0075] For example, in combination with Figure 1As shown, in the case that the charging request is a battery intelligent charging request, the embodiment of the present application can start the activation repair of the capacitor, and the OBC charges the high-voltage power battery to the electrolytic capacitor by controlling the on-off of the switch tube, maintains the voltage between the two ends of the electrolytic capacitor to a certain threshold, and activates the repair by applying voltage to the electrolytic capacitor until the vehicle meets certain power-off conditions.

[0076] Optionally, in an embodiment of the present application, charging the voltage of the electrolytic capacitor to a preset threshold value comprises: obtaining an actual voltage value of the vehicle power battery; and charging the electrolytic capacitor according to the actual voltage value and the preset threshold value until the voltage of the electrolytic capacitor is charged to the preset threshold value.

[0077] In some embodiments, when charging the voltage of the electrolytic capacitor to a certain threshold value, the embodiment of the present application can obtain an actual voltage value of the vehicle power battery, and then charge the electrolytic capacitor according to the actual voltage value until it is charged to a certain threshold value.

[0078] In step S203, if the charging request is not a battery intelligent charging request and the charging request is not a fast charging no discharge charging request, the vehicle is charged based on the charging request until the vehicle meets the preset power-off condition.

[0079] In some embodiments, in the case that the charging request is not a battery intelligent charging request and is not a fast charging no discharge charging request, the embodiment of the present application can charge the vehicle based on the charging request until the vehicle meets a certain power-off condition.

[0080] The working principle of the activation method of the on-board charger electrolytic capacitor proposed by the embodiment of the present application will be introduced below in combination with a specific embodiment.

[0081] Among them, Figure 3 The flow chart of the working principle of the activation method of the on-board charger electrolytic capacitor provided by an embodiment of the present application.

[0082] Step S301: the vehicle is powered on and awakened.

[0083] Step S302: identify the charging request.

[0084] Among them, after controlling the vehicle to be powered on, the embodiment of the present application can control the VCU to identify the charging request and send it to the CAN bus, and then the OBC receives the CAN signal to judge whether the charging request is a battery intelligent charging request or a fast charging no discharge charging request.

[0085] Step S303: battery intelligent charging request.

[0086] In the case that the charging request is the smart battery charging request, the embodiment of the present application can start the activation repair of the electrolytic capacitor. The OBC charges the high-voltage power of the power battery to the electrolytic capacitor by controlling the on-off of the switch tube, maintains the voltage between the two ends of the electrolytic capacitor to a certain threshold, and activates the repair by applying voltage to the electrolytic capacitor until the vehicle meets certain power-off conditions.

[0087] Step S304: fast charging without discharging charging request.

[0088] In the case that the charging request is the fast charging without discharging charging request, the embodiment of the present application can start the activation repair of the electrolytic capacitor. The OBC charges the high-voltage power of the power battery to the electrolytic capacitor by controlling the on-off of the switch tube, maintains the voltage between the two ends of the electrolytic capacitor to a certain threshold, and activates the repair by applying voltage to the electrolytic capacitor until the vehicle meets certain power-off conditions.

[0089] Step S305: other charging request.

[0090] In the case that the charging request is not the smart battery charging request and not the fast charging without discharging charging request, the embodiment of the present application can charge the vehicle based on the charging request until the vehicle meets certain power-off conditions.

[0091] Step S306: determining whether the vehicle meets certain power-off conditions.

[0092] In the case that the vehicle meets certain power-off conditions, step S307 is performed; otherwise, step S302 is performed.

[0093] Step S307: the vehicle is powered off and hibernated.

[0094] The activation method of the electrolytic capacitor of the on-board charger provided by the embodiment of the present application can respond to the charging request of the vehicle smart battery system, control the vehicle to be powered on, and charge the voltage of the electrolytic capacitor to a certain threshold when the charging request is the smart battery charging request or the fast charging without discharging charging request, to repair the electrolytic capacitor until certain power-off conditions are met, and charge based on the charging request when the charging request is not the smart battery charging request or the fast charging without discharging charging request until certain power-off conditions are met. The electrolytic capacitor can be activated and repaired automatically without affecting the use of normal functions of the vehicle, delaying battery aging, prolonging the overall battery pack life, without the need to increase hardware, reducing cost, improving user satisfaction, improving charging efficiency and energy utilization. Thus, the technical problems in the related art, such as strong condition dependence, inability to meet fast charging without discharging charging request, low repair efficiency, poor environmental adaptability, and difficulty in applying to long-term non-use scenarios of the vehicle, are solved.
