[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the drawings; while "inside" and "outside" refer to the outline of the device.

[0046] At present, many commercial vehicles are equipped with dual-gun sockets. Commercial vehicles use a multi-circuit parallel connection solution for batteries. After parallel connection, the battery capacity is large, the charging current is large, and the output capacity of a single charging pile is small, which cannot fully utilize the charging capacity of the battery. For the scenario of a single pile with two guns, the current output capacity of a single pile is small, and the vehicle's ability to support dual-gun charging is not fully utilized. For scenarios that only support dual-pile dual-gun charging, if only a single charging pile is available, the current output capacity of a single pile with a single gun is small, and the output capacity of the vehicle's dual-gun socket and the charging pile cannot be fully utilized.

[0047] In view of this, the present application proposes a dual-gun charging control method for a vehicle, an electronic device and a computer storable medium to give full play to the charging capacity of the battery and the output capacity of the charging pile, and to output the maximum current to charge the vehicle's battery in both a single charging pile and a dual charging pile, thereby improving the charging efficiency.

[0048] like Figure 1 As shown, it is a flow chart of an embodiment of the dual-gun charging control method of a vehicle in an embodiment of the present application. The execution subject of the embodiment of the present application is an electric device or a control module in the electric device. The control module can be a battery management system (Battery Management System, BMS), a vehicle control unit (VCU), etc. The embodiment of the present application is described in detail by taking the execution subject as BMS as an example. The dual-gun charging control method of the vehicle includes:

[0049] 101. Obtain a maximum charging request current of the vehicle.

[0050] Among them, the vehicle in this embodiment is a vehicle equipped with a dual-gun socket (charging interface), such as a commercial vehicle equipped with a gun socket. In this embodiment, through the dual-gun socket on the vehicle, the dual charging guns of the charging pile can be inserted into the socket, and the two dual-gun sockets are used to connect the two charging guns on the charging pile. The two dual-gun sockets communicate with the BMS through two independently isolated CAN lines, so that they can be compatible with single-pile dual-gun charging and dual-pile dual-gun charging, and realize dual-gun charging at the same time. It can also break through the limitation of the battery charging capacity and the charging pile charging capacity caused by one CAN line communicating with the BMS under the preset protocol in the traditional solution.

[0051] The maximum charge request current refers to the maximum charge current currently allowed by the battery in the vehicle.

[0052] Specifically, the maximum charging request current of the vehicle can be determined by the current power of the battery and the current ambient temperature. It can be understood that in this embodiment, the maximum charging request current of the vehicle is used so that the request currents of the two guns can be allocated and adjusted based on the maximum charging request current to fully utilize the charging capacity of the battery of the vehicle.

[0053] In one embodiment, step 101 includes: determining the maximum charging request current based on the current charge level and current temperature of the vehicle.

[0054] Among them, the current power refers to the state of charge (SOC) of the vehicle's battery. The battery's SOC has a significant impact on the maximum charging current. According to experimental data, as the battery SOC increases, the maximum charging current of the lithium-ion battery decreases. This means that when the battery power is high, in order to protect the battery, the maximum allowed charging current will decrease.

[0055] The current temperature is the temperature of the battery in the current environment. The ambient temperature also has an important impact on the maximum charging current of the battery. The lower the temperature, the smaller the maximum charging current allowed; the higher the temperature, the larger the maximum charging current allowed. However, it should be noted that excessively high battery temperature may pose a safety hazard, so the charging current will also be limited.

[0056] Specifically, the BMS can determine the maximum charging request current based on the current power and current temperature obtained, thereby ensuring the accuracy and rationality of the maximum charging request current, to ensure safe and efficient charging of the battery, and to facilitate the subsequent reasonable allocation and adjustment of the request currents of the dual guns based on the maximum charging request current.

[0057] 102. Obtain a maximum output current of a target charging pile to which a first charging gun and a second charging gun of a pair of charging guns connected to the vehicle for communication.

[0058] Among them, the double gun refers to two charging guns inserted into the double gun socket of the vehicle to charge the vehicle, namely the first charging gun and the second charging gun. The target charging pile refers to the charging pile where the first charging gun and the second charging gun are located. The target charging pile can be one charging pile, namely a single pile, that is, the first charging gun and the second charging gun are charging guns of the same charging pile; the target charging pile can be two charging piles, namely a double pile, that is, the first charging gun and the second charging gun are charging guns of two charging piles respectively.

[0059] The maximum output current is used to characterize the charging current of the maximum output capacity of the charging pile. The maximum output current includes but is not limited to the maximum charging current of the target charging pile itself and the maximum output current of the charging gun on the target charging pile. In one example, for a single pile, the maximum output current of each charging gun in the double gun, that is, the first charging gun and the second charging gun, is 250A, and the maximum output current of the single pile itself is 400A.

[0060] Specifically, the maximum output current can be obtained according to the specifications of the target charging pile. It can be understood that in this embodiment, the maximum output current of the target charging pile is obtained so that the requested currents of the two guns can be allocated and adjusted based on the maximum output current, so as to fully utilize the output capacity of the charging pile and shorten the charging time.

[0061] In one embodiment, Figure 2 As shown, before step 102, it also includes:

[0062] 104. Obtain charging pile information of a target charging pile to which a first charging gun and a second charging gun in a pair of charging guns belong;

[0063] 105. If the charging pile information indicates that the target charging pile to which the first charging gun and the second charging gun belong is the same charging pile, determine that the target charging pile is a single pile;

[0064] 106. Otherwise, determine that the target charging pile is a double pile.

[0065] Specifically, the charging pile information can be a unique identifier of the charging pile, such as the number of the charging pile. When the first socket of the dual-gun socket of the vehicle is connected to the first charging gun, the message information sent by the first charging gun can be obtained during the process of the first socket interacting with the first charging gun in the charging communication protocol, and the charging pile information corresponding to the charging pile to which the first charging gun belongs, such as the first charging pile number, can be obtained from the message information. Correspondingly, the charging pile information corresponding to the charging pile to which the second charging gun belongs, such as the second charging pile number, can be obtained in the same way as obtaining the first charging pile number. Then it is determined whether the first charging number is the same as the second charging number. If they are the same, it can be determined as a single pile, and if they are different, it is determined as a double pile. It can be understood that in this embodiment, by identifying the single pile or double pile of the target charging pile, the request current of the charging gun can be reasonably and accurately allocated for the single pile double gun charging mode and the double pile double gun charging mode, so as to improve the accuracy of the request current of the charging gun, ensure that the battery of the vehicle can be safely charged, and improve the charging efficiency.

[0066] In one embodiment, Figure 3 As shown, step 102 includes:

[0067] 102A. If the target charging pile is a single pile, obtain the first maximum output current of the dual guns and the fourth maximum output current of the target charging pile; the maximum output current includes the first maximum output current and the fourth maximum output current.

[0068] 102B. If the target charging pile is a dual pile, obtain the second maximum output current of the first charging gun and the third maximum output current of the second charging gun; the maximum output current includes the second maximum output current and the third maximum output current.

[0069] Among them, the fourth maximum output current refers to the maximum output capacity of the target charging pile itself, that is, the maximum charging current of the target charging pile, that is, the maximum output current under the protocol corresponding to the two charging CAN lines. In the case where the target charging pile is a single pile, it corresponds to a fourth maximum output current. The maximum output currents of the two charging guns in a charging pile are the same. Therefore, the first maximum output current refers to the maximum output current of a charging gun in a charging pile.

[0070] It is worth noting that, since in the embodiment of the present application, the two dual-gun sockets use two independently isolated CAN lines to communicate with the BMS, that is, two independent charging CAN lines, the fourth maximum output current is the maximum output current of each line, which is the current under the corresponding protocol. Compared with the traditional solution, one charging CAN line is used, and the charging current of the target charging pile is only the current under the protocol corresponding to the one charging CAN line. Obviously, the fourth maximum output current in the embodiment of the present application is greater than the fourth maximum output current in the traditional solution, and thus can break through the limitation of the maximum output current of the charging pile under the protocol corresponding to the one charging CAN line in the traditional solution, and give full play to the charging capacity of the charging pile and the charging capacity of the battery. In the case where the target charging pile is a dual pile, the maximum output current of the dual guns of different charging piles is different. Therefore, the second maximum output current of the first charging gun and the third maximum output current of the second charging gun are obtained as the maximum output current under the dual pile, so that the request current of the charging gun can be allocated based on the maximum output current of the charging pile.

[0071] Specifically, since in the case of a single pile with two guns, the first maximum output current and the fourth maximum output current of the target charging pile have limitations on the distribution and adjustment of the requested current of the two guns, the first maximum output current and the fourth maximum output current are obtained as the maximum output current under a single pile, so that the requested current of the single pile with two guns can be accurately distributed based on the maximum output current.

[0072] Specifically, since in the case of dual piles and dual guns, the second maximum output current and the third maximum output current have limitations on the distribution and adjustment of the requested current of the dual guns, the second maximum output current and the third maximum output current are obtained as the maximum output current under the dual piles, so that the requested current of the dual piles and dual guns can be accurately distributed based on the maximum output current.

[0073] 103. Allocate corresponding first charging request current and second charging request current to the first charging gun and the second charging gun respectively according to the maximum charging request current and the maximum output current, so that the first charging gun and the second charging gun charge the vehicle according to the first charging request current and the second charging request current respectively.

[0074] Specifically, the first charging request current corresponding to the first charging gun and the second charging request current corresponding to the second charging gun may be allocated according to the smaller value of the maximum charging request current and the maximum output current.

[0075] It can be understood that since the maximum charging request current represents the maximum charging capacity of the battery and the maximum output current represents the maximum output capacity of the charging pile, the first charging gun and the second charging gun are allocated the corresponding first charging request current and second charging request current according to the smaller of the two, thereby ensuring the charging safety of the batteries in the charging pile and the vehicle, and since the output current of the dual guns is allocated according to the maximum charging request current of the vehicle and the maximum output current of the charging pile, the charging capacity of the vehicle's battery and the output capacity of the charging pile can be fully utilized, and the maximum current can be output to charge the vehicle's battery in both single and dual charging piles, thereby improving the charging efficiency.

[0076] In one embodiment, step 103 includes: if the fourth maximum output current is less than or equal to the maximum charging request current, allocating the first charging request current and the second charging request current according to the constraint that the sum of the request currents allocated by the first charging gun and the second charging gun is equal to the fourth maximum output current, and the request current allocated by the first charging gun and the request current allocated by the second charging gun are both less than or equal to the first maximum output current; if the fourth maximum output current is greater than the maximum charging request current, allocating the first charging request current and the second charging request current according to the constraint that the sum of the request currents allocated by the first charging gun and the second charging gun is equal to the maximum charging request current, and the request current allocated by the first charging gun and the request current allocated by the second charging gun are both less than or equal to the first maximum output current.

[0077] Specifically, when the charging mode of the vehicle is single-pile dual-gun charging, if the fourth maximum output current is less than or equal to the maximum charging request current, it indicates that the battery of the vehicle has a large charging capacity, so there is no need to consider whether the charging current of the charging gun will affect the battery charging safety and life. At the same time, in order to give full play to the output capacity of the charging pile, the request current allocated by the first charging gun and the second charging gun is equal to the fourth maximum output current. If the fourth maximum output current is greater than the maximum charging request current, it indicates that the charging pile has a large charging capacity, so it is necessary to consider whether the charging current of the charging gun will affect the battery charging safety and life. At the same time, in order to give full play to the output capacity of the charging pile, the first charging request current and the second charging request current can be determined according to the constraint conditions that the sum of the request current allocated by the first charging gun and the second charging gun is equal to the maximum charging request current, and the request current allocated by the first charging gun and the second charging gun is less than or equal to the first maximum output current, so that when a single charging pile is used, the maximum current can be output to charge the battery of the vehicle to improve the charging efficiency.

[0078] In one example, for a single pile, its fourth maximum output current is 400A, the first maximum output current is 250A, and the maximum charging request current of the vehicle is 560A. Both 400A and 400A are less than 560A. Therefore, it can be determined that the sum of the first request current I1 and the second request current I2 is 400A, and I1≤250A, I2≤250A, for example, I1=150A, I2=250A, and for another example, I1=200A, I2=200A.

[0079] In another example, for a single pile, its fourth maximum output current is 400A, the first maximum output current is 250A, and the maximum charging request current of the vehicle is 360A. Since 360A is greater than 400A, it can be determined that the sum of the first request current I1 and the second request current I2 is 360A, that is, the first request current and the second request current can be determined according to the following equation.

[0080] I1+I2=360A, and I1≤250A, I2≤250A;

[0081] For example, I1=150A, I2=210A, and for another example, I1=180A, I2=180A.

[0082] In one embodiment, the requested currents allocated by the first charging gun and the second charging gun are equal.

[0083] Specifically, the request currents allocated to the first charging gun and the second charging gun are equal, that is, the first charging request current and the second charging request current are evenly distributed, so that the two guns can be charged simultaneously under a single pile, and the two guns can complete the charging of the battery at the same time, thereby improving the user experience.

[0084] In one embodiment, step 103 includes: if the sum of the second maximum output current and the third maximum output current is greater than the maximum charging request current, the first charging request current and the second charging request current are allocated according to the constraint that the sum of the request currents allocated by the first charging gun and the second charging gun is equal to the maximum charging request current, and the request current allocated by the first charging gun is less than or equal to the second maximum output current, and the request current allocated by the second charging gun is less than or equal to the third maximum output current; if the sum of the second maximum output current and the third maximum output current is less than or equal to the maximum charging request current, then the first charging request current is determined to be the second maximum output current, and the second charging request current is determined to be the third maximum output current.

[0085] Specifically, if the sum of the second maximum output current and the third maximum output current is greater than the maximum charging request current, it indicates that the charging pile has a large charging capacity. Therefore, it is necessary to consider whether the charging current of the charging gun will affect the battery charging safety and life. At the same time, in order to give full play to the output capacity of the charging pile, the first charging request current and the second charging request current are allocated according to the constraint that the sum of the request currents allocated by the first charging gun and the second charging gun is equal to the maximum charging request current, and the request current allocated by the first charging gun is less than or equal to the second maximum output current, and the request current allocated by the second charging gun is less than or equal to the third maximum output current; if the sum of the second maximum output current and the third maximum output current is less than or equal to the maximum charging request current, it indicates that the battery of the vehicle has a large charging capacity. Therefore, there is no need to consider whether the charging current of the charging gun will affect the battery charging safety and life. At the same time, in order to give full play to the output capacity of the charging pile, the first charging request current is determined to be the second maximum output current and the second charging request current is determined to be the third maximum output current. In the case of dual charging piles, the maximum current can be output to charge the battery of the vehicle, thereby improving the charging efficiency.

[0086] In one example, for a dual charging pile, the second maximum output current is 250A, the third maximum output current is 300A, and the maximum charging request current of the vehicle is 460A. Since 460A is less than 250A+300A, it can be determined that the sum of the first request current I1 and the second request current I2 is 660A, that is, the first request current and the second request current can be determined according to the following equation.

[0087] I1+I2=460, and I1≤250A, I2≤300A.

[0088] In one example, for a dual charging pile, the second maximum output current is 250A, the third maximum output current is 300A, and the maximum charging request current of the vehicle is 660A. Since 660A is greater than 250A+300A, it can be determined that the first request current I1 is 250A and the second request current I2 is 300A.

[0089] The dual-gun charging control method for the above-mentioned vehicle obtains the maximum output current of the target charging pile to which the first charging gun and the second charging gun of the dual gun belong; and allocates the corresponding first charging request current and second charging request current to the first charging gun and the second charging gun according to the maximum charging request current and the maximum output current, so that the first charging gun and the second charging gun charge the vehicle according to the first charging request current and the second charging request current, respectively. Since the output current of the dual guns is allocated according to the maximum charging request current of the vehicle and the maximum output current of the charging pile, the charging capacity of the vehicle's battery and the output capacity of the charging pile can be fully utilized. The maximum current can be output to charge the vehicle's battery in both single and dual charging piles, thereby improving the charging efficiency.

[0090] like Figure 4 As shown, the embodiment of the present application further provides a dual-gun charging control device 200 for a vehicle, and the dual-gun charging control device 200 for a vehicle includes:
