[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] It should be noted that, based on this disclosure, those skilled in the art will understand that one aspect described herein can be implemented independently of any other aspect, and two or more of these aspects can be combined in various ways. For example, any number of aspects set forth herein can be used to implement the device and / or practice the method. Furthermore, this device and / or practice the method can be implemented using other structures and / or functionalities besides one or more of the aspects set forth herein.

[0017] The following will refer to Figure 1 The flowchart shown illustrates a method for parallel charging of multiple mobile charging vehicles, introducing such a method.

[0018] This parallel charging method for multiple mobile charging vehicles is applied to any one of n mobile charging vehicles. Each mobile charging vehicle includes: a return charging port, a charging gun, a battery, a first switch S1, and a second switch S2. The return charging port and the charging gun of each mobile charging vehicle are connected by a main conductor. The charging end of the battery is connected to the main conductor through S1, and the discharging end of the battery is connected to the main conductor through S2. The charging gun of any mobile charging vehicle is connected to the return charging port of the next mobile charging vehicle, and the return charging port of the first mobile charging vehicle is connected to the charging gun of the charging pile.

[0019] In this embodiment, the recharge port of the mobile charging vehicle is used to charge the mobile charging vehicle, and the charging gun of the mobile charging vehicle is used to connect to the next mobile charging vehicle or to charge a new energy vehicle; the first switch S1 can be a relay or a contactor, and the second switch S2 can be a relay or a contactor, which can be selected according to actual needs; the charging end of the battery has charging and discharging functions.

[0020] The specific connection method for n mobile charging vehicles is as follows: the charging gun of the preset charging pile is inserted into the return charging port of the first mobile charging vehicle, the charging gun of the first mobile charging vehicle is inserted into the return charging port of the second mobile charging vehicle, the charging gun of the second mobile charging vehicle is inserted into the return charging port of the third mobile charging vehicle, and so on, connecting the n mobile charging vehicles in sequence. It can be understood that the charging gun of the last mobile charging vehicle is in an idle state, i.e., in a suspended state. It should be noted that the return charging port and the charging gun of each mobile charging vehicle are connected through a main wire. Therefore, the n mobile charging vehicles are connected in parallel.

[0021] The method for parallel charging of multiple mobile charging vehicles may include the following steps: S100, obtain the current status of the mobile charging vehicle's return charging port HC. now And the current status CD of the charging gun in the mobile charging vehicle. now .

[0022] In this embodiment, whether the mobile charging vehicle's return port is plugged into a charging gun and whether its own charging gun is connected to other devices can be directly obtained through its own detection and control system; therefore, the HC can be obtained through the current mobile charging vehicle's detection and control system. now and CD now The state is not idle when the charging port is inserted into the charging gun, and it is idle when the charging port is not inserted into the charging gun. The state is not idle when the charging gun of the mobile charging vehicle is inserted into the next mobile charging vehicle, and it is idle when the charging gun of the mobile charging vehicle is suspended in the air.

[0023] It is understandable that the status of the charging gun of the current mobile charging vehicle is the same as the status of the return charging port of the next connected mobile charging vehicle.

[0024] S200, if HC now The default non-idle state and CD now If the preset idle state is met, then the current battery level Q of the mobile charging vehicle is obtained. now .

[0025] In this embodiment, if HC now The default non-idle state and CD now If the preset idle state is selected, it means that the current mobile charging vehicle is the last one. At this time, the detection and control system of the current mobile charging vehicle can obtain its own battery power.

[0026] S300, if Q nowIf <Q', then control the S1 of the current mobile charging vehicle to close and control the S2 of the current mobile charging vehicle to open; where Q' is a preset first power threshold.

[0027] In this embodiment, it is first determined whether the current battery level of the mobile charging vehicle is less than a preset first battery level threshold Q', for example, Q' can be set to 90%; if Q' is less than 90%, then the battery level is determined to be less than 90%. now If <Q', it means that the current mobile charging vehicle's battery level meets the conditions for continued charging. In this case, the current mobile charging vehicle's S1 is closed and its S2 is opened, allowing the charging pile to charge the last mobile charging vehicle and continuously acquire the current mobile charging vehicle's battery level until it is fully charged.

[0028] S400, if Q now If ≥Q', then control the S1 of the current mobile charging vehicle to disconnect and control the S2 of the current mobile charging vehicle to close; proceed to step S500.

[0029] In this embodiment, if Q now If ≥Q' indicates that the current mobile charging vehicle's battery level is too high and does not meet the conditions for continuing charging, then control the current mobile charging vehicle's S1 to disconnect and control the current mobile charging vehicle's S2 to close, thereby disconnecting the current mobile charging vehicle from the charging pile and stopping charging.

[0030] S500 sets the current mobile charging vehicle's return port status to a preset idle state and sets the previous mobile charging vehicle's charging gun status to a preset idle state.

[0031] In this embodiment, after the current mobile charging vehicle is fully charged, the state of the current mobile charging vehicle's return charging port is set to a preset idle state, and the state of the charging gun of the previous mobile charging vehicle is set to a preset idle state, so that the previous mobile charging vehicle connected to the current mobile charging vehicle, i.e. the last mobile charging vehicle, is equivalent to the last mobile charging vehicle, thereby enabling the process to enter step S100 to continue executing the above steps and perform charging.

[0032] If the last mobile charging vehicle is disconnected from the previous mobile charging vehicle by the user before its battery is fully charged, then the previous mobile charging vehicle becomes the last mobile charging vehicle, and step S100 can be executed to charge it.

[0033] In this embodiment, the parallel charging method for multiple mobile charging vehicles involves connecting the charging gun of any one of the n mobile charging vehicles to the return charging port of the next mobile charging vehicle, and connecting the return charging port of the first mobile charging vehicle to the charging gun of the charging pile. The current status HC of the return charging port of the mobile charging vehicle is obtained. now And the current status CD of the charging gun in the mobile charging vehicle.now According to HC now and CD now To determine if the current mobile charging vehicle is the one that needs charging; if it is, to obtain the current battery level Q of the mobile charging vehicle. now If Q now If Q' < Q', then control S1 is closed and control S2 is open; thus, the current mobile charging vehicle is charged; if Q now ≥Q' indicates that charging is complete, then control S1 is disconnected and control S2 is closed; thus, charging can be carried out sequentially from the last connected mobile charging vehicle. The whole charging process is relatively simple and does not require dedicated personnel to operate, making it convenient.

[0034] In addition, when users use mobile charging carts, they can use the last connected mobile charging cart first, and the last connected mobile charging cart also has the largest battery capacity, which meets the needs of actual use scenarios; and the last connected mobile charging cart only connects to the charging gun of the previous mobile charging cart through its own return port, so disconnecting does not affect the remaining mobile charging carts from continuing to charge, further improving convenience.

[0035] Furthermore, after step S100 and before step S200, the method includes the following steps: S110, if HC now and CD now If both are in a preset non-idle state, then S1 and S2, which control the current mobile charging vehicle, will be disconnected.

[0036] In this embodiment, if HC now and CD now If both are in a preset non-idle state, it means that the current mobile charging vehicle's return port is plugged into a charging gun, and the current mobile charging vehicle's charging gun is also plugged into the return port of another mobile charging vehicle. It can be determined that the current mobile charging vehicle is not the last mobile charging vehicle. Therefore, S1 and S2 of the current mobile charging vehicle should be disconnected so that the current mobile charging vehicle is in a queue waiting to be charged.

[0037] S120, if HC now If the preset idle state is met, then control the S1 switch of the current mobile charging vehicle to open and control the S2 switch of the current mobile charging vehicle to close.

[0038] In this embodiment, if HC now The preset idle state indicates that the charging port of the current mobile charging vehicle is not plugged into the charging gun. In this case, the S1 control of the current mobile charging vehicle is opened and the S2 control of the current mobile charging vehicle is closed, so that the current mobile charging vehicle can charge external new energy vehicles at any time.

[0039] Furthermore, prior to step S100, the method may include the following steps: S010, Get the current time t now .

[0040] S011, if t now If the mobile charging vehicle is charged within the preset charging time period T1, then proceed to step S100; wherein, within T1, the charging gun of the charging pile operates in the external discharge mode.

[0041] In this embodiment, the charging period for the mobile charging vehicle is generally at night, for example, T1 is from 22:00 on the same day to 6:00 on the next day. During this period, the mobile charging vehicle is used less frequently by users, making it suitable for charging during this time. It should be noted that the charging pile has two operating modes: an external discharge mode, in which the charging pile can charge the mobile charging vehicle; and a reverse power supply mode, in which the charging pile can receive the power provided by the mobile charging vehicle and feed it back to the power grid to balance the load pressure on the power grid.

[0042] Furthermore, the mobile charging vehicle also includes a third switch S3; wherein, one end of S3 is connected to the return charging port of the mobile charging vehicle, and the other end is connected to the connection terminal of S1 and the main conductor; S3 can be a relay or a contactor; step S500 may include the following steps: S510 controls the S3 of the current mobile charging vehicle to disconnect, so that the state of the current mobile charging vehicle's return charging port and the state of the previous mobile charging vehicle's charging gun are both in the preset idle state.

[0043] In this embodiment, after S3 is disconnected, although the charging gun of the previous mobile charging vehicle is still plugged into the return port of the current mobile charging vehicle, the charging gun of the previous mobile charging vehicle has actually been disconnected from the return port of the current mobile charging vehicle. Therefore, when S3 is disconnected, the state of the return port of the current mobile charging vehicle and the state of the charging gun of the previous mobile charging vehicle are both preset idle states.

[0044] In this embodiment, by setting S3, the state of the current mobile charging vehicle's return port and the state of the previous mobile charging vehicle's charging gun are both preset to be idle. The mobile charging vehicle's processor does not need to process complex control information; it only needs to control the on / off state of S3. There is also no need to communicate with adjacent connected mobile charging vehicles, making the control of the charging sequence of the mobile charging vehicles simpler and more reliable.

[0045] In addition, using the above method, when the last mobile charging vehicle is fully charged and has not been disconnected by the user, it can automatically switch to charging the previous mobile charging vehicle, thus achieving unattended charging.

[0046] Furthermore, the range of Q' can be 0.85-0.95, for example, Q' is 0.9; the range of Q' can also be adjusted according to actual needs.

[0047] Furthermore, Q' depends on the current t now The preset charging time period T1 for the mobile charging vehicle is determined, which may specifically include the following steps: S310, Get the current time t now .

[0048] S320, if t now Within T1, the start time t1 and end time t2 corresponding to T1 are obtained.

[0049] S330, obtain t now The time interval TA and t1 now The time interval TB between t2 and t2.

[0050] S340, obtain the target time interval TC=MIN(TA, TB) and the preset range FQ=[FQ1,FQ2] corresponding to Q'; where MIN() is the preset minimum value function; FQ1 is the minimum first power threshold corresponding to Q', and FQ2 is the maximum first power threshold corresponding to Q'.

[0051] In this embodiment, for example, FQ1 can be 0.85 and FQ2 can be 0.95.

[0052] S350, based on TC, T1 and FQ, determine Q'=FQ1+TC×(FQ2-FQ1) / (0.5×(t2-t1)).

[0053] In this embodiment, Q' determined by the above method is dynamically variable because the middle time of T1 is the time when the mobile charging vehicle has the lowest probability of being used. At this time, setting Q' to be larger can ensure that each mobile charging vehicle has a higher battery level when fully charged; while t now The smaller the time interval between t1 or t2, the greater the probability that the mobile charging vehicle will be used. In this case, setting Q' to a smaller value can increase the charging speed of the mobile charging vehicle, thereby providing users with a larger number of fully charged mobile charging vehicles.

[0054] In one exemplary embodiment, the mobile charging vehicle itself has a battery; therefore, the mobile charging vehicle can also be used as an energy storage device. Based on the connection method of n mobile charging vehicles in the above embodiment, an unattended automated reverse power feedback method is provided. Specifically, the method may include the following steps: T100, if the charging gun connected to the current mobile charging vehicle's return port is the charging gun of the charging pile, then send the first preset control command ZL1 to the next mobile charging vehicle connected to the current mobile charging vehicle, so that the next mobile charging vehicle sets the state of its return port to the preset idle state through ZL1; otherwise, proceed to step T500.

[0055] In this embodiment, the recharge port of the mobile charging vehicle has a communication function, which can obtain the device information of the connected device. Thus, it can determine whether the charging gun connected to the current mobile charging vehicle's recharge port is the charging gun of the charging pile through the obtained device information. If the charging gun connected to the current mobile charging vehicle's recharge port is the charging gun of the charging pile, it means that the current mobile charging vehicle is the first mobile charging vehicle. ZL1 is used to set the state of the corresponding recharge port to an idle state. The idle state can be understood as the state where no charging gun is inserted.

[0056] T200 controls the current mobile charging vehicle's S1 to close and the current mobile charging vehicle's S2 to open.

[0057] In this embodiment, the reverse power supply sequence of the mobile charging vehicle is as follows: first, power is supplied to the mobile charging vehicle connected to the charging pile. If the charging gun connected to the current mobile charging vehicle's return port is the charging gun of the charging pile, then the current mobile charging vehicle's S1 is closed and the current mobile charging vehicle's S2 is opened, so that the current mobile charging vehicle is connected to the charging gun of the charging pile.

[0058] T300, obtain the current battery level Q of the mobile charging vehicle. now Q now For percentages, such as Q now =90% means that the current battery level of the mobile charging vehicle is 90% of its full capacity.

[0059] In this embodiment, Q now This information can be obtained through the current detection and control system of mobile charging vehicles.

[0060] T400, if Q now If WT < WT, then the current mobile charging vehicle's S1 is disconnected; and a second preset control command ZL2 is sent to the next mobile charging vehicle connected to the current mobile charging vehicle, so that the next mobile charging vehicle sets its own recharge port status to a preset non-idle state through ZL2; where WT is a preset second power threshold.

[0061] In this embodiment, during the current reverse power feeding process of the mobile charging vehicle, Q is acquired in real time. now If Q now <WT indicates that the battery power of the current mobile charging vehicle is low and the power dissipation process can be considered to be completed. In this case, the S1 of the current mobile charging vehicle is disconnected, thereby disconnecting the battery of the current mobile charging vehicle from the charging gun of the charging pile. The range of WT can be 0.2-0.3.

[0062] Send a second preset control command ZL2 to the next mobile charging vehicle connected to the current mobile charging vehicle, so that the next mobile charging vehicle sets the state of its own return port to a preset non-idle state through ZL2, and can connect the next mobile charging vehicle to the charging gun of the charging pile through the main wire of the current mobile charging vehicle.

[0063] T500, obtains the battery level Q' of the previous mobile charging vehicle connected to the current mobile charging vehicle. now .

[0064] In this embodiment, the current mobile charging vehicle can communicate with the preceding and following mobile charging vehicles to obtain the battery power of the preceding mobile charging vehicle.

[0065] T600, according to Q' now It controls the current mobile charging vehicle to provide reverse power to the charging pile.

[0066] Furthermore, step T600 may include the following steps: T610, if Q' now If the value is less than WT, then control the S1 switch of the current mobile charging vehicle to close and control the S2 switch of the current mobile charging vehicle to open.

[0067] In this embodiment, the current mobile charging vehicle is not the first mobile charging vehicle, that is, it is not a mobile charging vehicle directly connected to the charging gun of the charging pile; at this time, it is necessary to determine whether the previous mobile charging vehicle has completed reverse power feeding, if Q' now <WT indicates that the previous mobile charging vehicle has completed reverse power feeding. Then, control the current mobile charging vehicle's S1 to close, so that the current mobile charging vehicle can connect to the charging pile. Control the current mobile charging vehicle's S2 to open, so as to turn off the mobile charging vehicle's external charging function.

[0068] T611, retrieve the current battery level Q of the mobile charging vehicle. now .

[0069] T612, if Q nowIf <WT, then the S1 of the current mobile charging vehicle is disconnected; and ZL2 is sent to the next mobile charging vehicle connected to the current mobile charging vehicle, so that the next mobile charging vehicle sets the state of its own return port to the preset non-idle state through ZL2.

[0070] In the current process of reverse power feeding from mobile charging vehicles, Q is acquired in real time. now If Q now <WT indicates that the battery power of the current mobile charging vehicle is low and the power depletion process can be considered complete. In this case, the S1 of the current mobile charging vehicle is disconnected, thereby disconnecting the battery of the current mobile charging vehicle from the charging gun of the charging pile.

[0071] Send ZL2 to the next mobile charging vehicle connected to the current mobile charging vehicle, so that the next mobile charging vehicle sets the status of its return port to a preset non-idle state through ZL2, and can connect the next mobile charging vehicle to the charging gun of the charging pile through the main wire of the current mobile charging vehicle.

[0072] Furthermore, step T600 may also include the following steps: T630, if Q' now If the value is less than WT, then the number of target mobile charging vehicles NUM is obtained; where the target mobile charging vehicle is the mobile charging vehicle connected to the current mobile charging vehicle before it and whose battery capacity is less than WT.

[0073] T631, determine the weight ω=NUM / n of the mobile charging vehicle that has been fully charged based on NUM and n.

[0074] T632, if ω≥ω', then set the current mobile charging vehicle's recharge port status to the preset idle state to stop the current mobile charging vehicle's reverse power supply; ω' is the preset weight threshold for mobile charging vehicles that have been fully powered.

[0075] In this embodiment, during the reverse power feeding process of the n mobile charging vehicles, there will be situations where users use the mobile charging vehicles. Therefore, during the reverse power feeding process of the n mobile charging vehicles, a portion of the mobile charging vehicles are reserved not to perform reverse power feeding to cope with situations where users suddenly need to use mobile charging; for example, ω'≥0.3; that is, at least 30% of the mobile charging vehicles are reserved not to perform reverse power feeding.

[0076] Furthermore, the mobile charging vehicle also includes a third switch S3; wherein, one end of S3 is connected to the return charging port of the mobile charging vehicle, and the other end is connected to the connection terminal of S1 and the main conductor; the mobile charging vehicle sets the state of its return charging port to a preset non-idle state through ZL2, including the following steps: T410 controls the S3 of the next mobile charging vehicle to disconnect, so that the return charging port of the next mobile charging vehicle is in a preset idle state.

[0077] In this embodiment, after the next mobile charging vehicle control S3 is disconnected, although the charging gun of the previous mobile charging vehicle is still plugged into the return port of the next mobile charging vehicle, the charging gun of the previous mobile charging vehicle has actually been disconnected from the return port of the next mobile charging vehicle. Therefore, when the next mobile charging vehicle is disconnected from S3, the state of the return port of the next mobile charging vehicle and the state of the charging gun of the previous mobile charging vehicle are both preset idle states.

[0078] In this embodiment, by setting S3, the state of the current mobile charging vehicle's return port and the state of the previous mobile charging vehicle's charging gun are both preset to be idle. The mobile charging vehicle's processor does not need to process complex control information; it only needs to control the on / off state of S3, making the control of the mobile charging vehicle's reverse power feeding sequence simpler and more reliable.

[0079] Furthermore, prior to step T100, the method further includes the following steps: T010, Get the current time t now .

[0080] T011, if t now If the mobile charging vehicle is in reverse power feeding time T2 within the preset time period, then proceed to step T100; wherein, during T2, the charging gun of the charging pile is in reverse power feeding mode.

[0081] In this embodiment, the reverse power feeding period of the mobile charging vehicle is generally during the peak electricity consumption period during the day, for example, T2 is 18:00-20:00 on the same day. During this period, the grid load is high, and reverse power feeding can be performed on the grid during this period to balance the load pressure on the grid. It should be noted that the charging pile has two working modes: an external discharge mode, in which the charging pile can charge the mobile charging vehicle; and a reverse power feeding mode, in which the charging pile can receive the power provided by the mobile charging vehicle and transmit the power provided by the mobile charging vehicle back to the grid to balance the grid load pressure.

[0082] In this embodiment of the multi-mobile charging vehicle parallel reverse power feeding method, if the charging gun connected to the return charging port of the current mobile charging vehicle is a charging gun of a charging pile, then a first preset control command ZL1 is sent to the next mobile charging vehicle connected to the current mobile charging vehicle, causing the next mobile charging vehicle to set its own return charging port to a preset idle state through ZL1; the current mobile charging vehicle's S1 is controlled to close, and the current mobile charging vehicle's S2 is controlled to open, so that the current mobile charging vehicle is providing reverse power to the charging pile; and the battery power of the current mobile charging vehicle is obtained. If the battery power of the current mobile charging vehicle is less than a preset second power threshold, then the current mobile charging vehicle's S1 is controlled to open, ending the current mobile charging vehicle's power feeding; and a second preset control command ZL2 is sent to the next mobile charging vehicle connected to the current mobile charging vehicle, causing the next mobile charging vehicle to set its own return charging port to a preset non-idle state through ZL2; if the charging gun connected to the return charging port of the current mobile charging vehicle is not a charging gun of a charging pile, then the battery power Q' of the previous mobile charging vehicle connected to the current mobile charging vehicle is obtained. now According to Q' now It controls the current mobile charging vehicle to provide reverse power to the charging pile; thus realizing the automatic reverse power feeding process of multiple mobile charging vehicles; since the entire reverse power feeding process of multiple mobile charging vehicles is automated, the entire power feeding process is relatively simple and does not require dedicated personnel to operate, making reverse power feeding highly convenient.

[0083] Furthermore, although the steps of the method in this disclosure are described in a specific order in the accompanying drawings, this does not require or imply that the steps must be performed in that specific order, or that all the steps shown must be performed to achieve the desired result.
