For example, the response frame includes the number 123456 of the charging stake 400 corresponding to the second charging gun 420, the number 123478 of the charging stake 400 corresponding to the first charging gun 410, and the charging stake 400 numbers of the two charging guns are different, so that the target charging mode is determined to be the second dual-gun charging mode, i.e. the dual-gun parallel charging mode.

In some embodiments, controlling the power output state of the first charging gun 410 based on the charging heartbeat frames fed back by the second charging gun 420 at the target time interval includes:

In the case where the charging heartbeat frame transmitted by the second charging gun 420 at the target time interval is not received, the power output state of the first charging gun 410 is controlled based on the charging data frame.

In this embodiment, the situation that the charging heartbeat frame sent by the second charging gun 420 according to the target time interval is not received may be that the second charging gun 420 exits the charging state, or the second charging gun 420 fails, at which time the second charging gun 420 no longer charges the chargeable device 300, and the first charging gun 410 alone charges the chargeable device 300.

In this embodiment, when the first charging gun 410 charges the rechargeable device 300 alone, the required power of the rechargeable device 300 may be determined according to the charging data frame, and the first charging gun 410 controls its power output to satisfy the required power of the rechargeable device 300.

In some embodiments, in the event that the second charging gun 420 determines, based on the charging data frame, that the chargeable device 300 enters a trickle charge phase, no charging heartbeat frame sent by the second charging gun 420 is received.

The trickle charge phase is used to compensate for the capacity loss of the rechargeable device 300 due to self-discharge after full charge, and a small current is required to charge the rechargeable device 300 at a low charge rate.

In this embodiment, the battery management system 320 may reduce the current demand to cause the rechargeable device 300 to enter a trickle charge phase based on the current state of charge of the rechargeable device 300.

In actual implementation, the second charging gun 420 monitors the charging data frame to acquire the current required voltage and current of the rechargeable device 300, when the required power is reduced to a certain value, the remaining capacity of the battery pack 310 is greater than a certain value, and after the state lasts for a certain time, the second charging gun 420 determines that the rechargeable device 300 enters the trickle charging stage at this time, and automatically exits the charging state.

For example, when the required power is reduced to less than half of the power value of the entire charging pile 400, the remaining power of the battery pack 310 is greater than 90%, and after the state lasts for a certain time, the second charging gun 420 determines that the rechargeable device 300 enters the trickle charging phase at this time, and automatically exits the charging state.

In this embodiment, when the rechargeable device 300 enters the trickle charging stage, the required power is reduced, and the charging gun alone can meet the requirement of the rechargeable device 300, and the second charging gun 420 can determine that the rechargeable device 300 enters the trickle charging stage through the charging data frame, and automatically exits the charging state, and the first charging gun 410 charges the rechargeable device 300 alone, and the second charging gun 420 can be used to charge other devices, so as to improve the working efficiency and the utilization rate of the charging pile 400.

upon receiving the charging heartbeat frame transmitted by the second charging gun 420 at the target time interval, the power output state of the first charging gun 410 is controlled based on the charging data frame and the charging heartbeat frame.

In this embodiment, a charging heartbeat frame sent by the second charging gun 420 at the target time interval is received, indicating that the second charging gun 420 is in a state of charging the chargeable device 300 at this time, i.e., the first charging gun 410 and the second charging gun 420 remain while charging the chargeable device 300.

In this embodiment, the charging heartbeat frame may include the charging state of the second charging gun 420, the first charging gun 410 may determine the required power of the rechargeable device 300 according to the charging data frame, and in combination with the charging state of the second charging gun 420, the first charging gun 410 and the second charging gun 420 may allocate the tasks of providing the required power to the rechargeable device 300, for example, the first charging gun 410 and the second charging gun 420 may equally allocate the tasks of providing the required power to the rechargeable device 300.

The embodiment of the application provides a charging method of a rechargeable device 300 applied to a second charging gun 420.

As shown in fig. 2, the charging method of the rechargeable device 300 includes: step 210, step 220, step 230 and step 240.

Step 210, when receiving the probe frame sent by the first charging gun 410, feeding back a response frame to the first charging gun 410.

The detection frame is used for the first charging gun 410 to make a request for establishing connection to the second charging gun 420, and provides related information to the second charging gun 420, such as an order number of the first charging gun 410, a number of the charging pile 400 where the first charging gun 410 is located, etc., and the second charging gun 420 may perform operations of determining whether to set the same charging pile 400 as the first charging gun 410, etc., based on the information.

In this embodiment, the response frame is used to inform the first charging gun 410 that the second charging gun 420 has received the corresponding detection frame, and can establish a connection with the first charging gun 410 and provide information related to the first charging gun 410, for example, the number of the charging pile 400 where the second charging gun 420 is located, the current working state of the second charging gun 420, etc., and based on these information, the first charging gun 410 can perform operations of determining whether to set the same charging pile 400 as the second charging gun 420.

In this embodiment, after the first charging gun 410 receives the response frame, the first charging gun 410 and the second charging gun 420 formally establish a communication connection.

In actual implementation, the second charging gun 420 may receive the probe frame multiple times, and the second charging gun 420 feeds back the response frame immediately after receiving the probe frame for the first time.

Step 220, charging the chargeable device 300 based on the detection frame.

In this embodiment, after receiving the detection frame and feeding back the response frame, the second charging gun 420 establishes a communication connection with the first charging gun 410, immediately requests charging to the charging post 400 where the first charging gun 410 is located after determining that the first charging gun 410 is in the charging state, and enters the charging state after feeding back the charging post 400 to charge the chargeable device 300.

In this embodiment, the second charging gun 420 may determine a corresponding charging mode according to the comparison between the number information of the charging post 400 where the first charging gun 410 is located and the number information of the charging post 400 where the second charging gun is located in the detection frame, so as to charge the rechargeable device 300.

Step 230, monitor the charging data frame of the chargeable device 300.

The charging data frame is used to provide the charging state of the rechargeable device 300, and may include a battery state parameter of the rechargeable device 300, and the like.

In this embodiment, the battery management system 320 sends a charging data frame to the first charging gun 410, after the first charging gun 410 establishes a connection with the second charging gun 420, the second charging gun 420 may monitor the charging data frame, and the second charging gun 420 may determine the charging state of the chargeable device 300 according to the charging data frame.

Step 240, sending a charging heartbeat frame to the first charging gun 410 at a target time interval.

The target time interval is a preset value, which indicates a duration of an interval between two transmission charging heartbeat frames when the second charging gun 420 charges the rechargeable device 300.

In this embodiment, the charging heartbeat frame may include a charging state of the second charging gun 420, and the first charging gun 410 may allocate a task of charging the chargeable device 300 to the second charging gun 420 according to the charging state of the second charging gun 420.

In this embodiment, the second charging gun 420 only carries out the charge state judgment of the chargeable device 300 according to the message sent and received between the first charging gun 410 and the BMS, and compared with the complete charging process of the standard GB/T27930, the charging process of the second charging gun 420 is simplified in this scheme.

As shown in fig. 6, the charge state of the second charge gun 420 may include: idle state, insulation detection end, timeout reconnection state, precharge state, in-charge state, and charge end state.

It should be noted that, in the charging process, if the first charging gun 410 fails, the charging process is actively exited, and after the second charging gun 420 knows that the communication between the first charging gun 410 and the BMS is stopped, the charging process is automatically exited, and the charging process is in a charging end state.

In some embodiments, charging the chargeable device 300 based on the probe frame includes:

determining a target charging mode based on the detection frame;

The target charging mode is a mode in which the second charging gun 420 charges the rechargeable device 300.

In this embodiment, determining the target charging mode based on the detection frame may be determining whether the first charging gun 410 and the second charging gun 420 are on the same charging pile based on the information of the charging pile 400 where the first charging gun 410 is included in the detection frame, so as to determine the target charging mode.

In some embodiments, determining the target charging mode based on the probe frame comprises:

in the case where it is determined that the number of the charging stake 400 corresponding to the first charging gun 410 and the number of the charging stake 400 corresponding to the second charging gun 420 are the same based on the detection frame, the target charging mode is determined to be the first dual-gun charging mode.

In this embodiment, the detection frame includes the number of the charging post 400 corresponding to the first charging gun 410, and the number of the charging post 400 corresponding to the first charging gun 410 and the number of the charging post 400 corresponding to the second charging gun 420 are compared, where the first charging gun 410 and the second charging gun 420 are determined to be in the same charging post 400 under the condition that the numbers of the charging posts 400 are the same, so that the target charging mode is determined to be the dual-gun same charging mode.

For example, the detection frame includes a number 123456 of the charging piles 400 corresponding to the first charging gun 410, a number 123456 of the charging piles 400 corresponding to the second charging gun 420, and the charging piles 400 of the two charging guns are the same, and then the target charging mode is determined to be the first dual-gun charging mode, i.e. the dual-gun co-charging mode.

in the case that it is determined that the number of the charging post 400 corresponding to the first charging gun 410 and the number of the charging post 400 corresponding to the second charging gun 420 are different based on the detection frame, the target charging mode is determined to be the second dual-gun charging mode.

For example, the detection frame includes a number 123456 of the charging piles 400 corresponding to the first charging gun 410, a number 123478 of the charging piles 400 corresponding to the first charging gun 410, and different numbers of the charging piles 400 of the two charging guns, and then the target charging mode is determined to be the second dual-gun charging mode, i.e. the dual-gun parallel charging mode.

In some embodiments, sending the charging heartbeat frame to the first charging gun 410 at the target time interval includes:

in the event that it is determined, based on the charging data frame, that the chargeable device 300 enters the trickle charge phase, the transmission of the charging heartbeat frame to the first charging gun 410 is stopped.

In actual implementation, the second charging gun 420 monitors the charging data frame, knows the current required voltage and current of the rechargeable device 300, and after the required power is reduced to a certain value and the remaining power of the battery pack 310 is greater than a certain value, and the state lasts for a certain time, the second charging gun 420 determines that the rechargeable device 300 enters the trickle charging stage at this time, automatically exits from the charging state, and stops sending the charging heartbeat frame to the first charging gun 410.

For example, when the required power is reduced to less than half of the power value of the entire charging pile 400, the remaining power of the battery pack 310 is greater than 90%, and after the state lasts for a certain time, the second charging gun 420 determines that the rechargeable device 300 enters the trickle charging phase at this time, automatically exits the charging state, and stops sending the charging heartbeat frame to the first charging gun 410.
