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. The return charging port of the mobile charging vehicle has charging and discharging functions.

[0019] In this embodiment, the return charging 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 the next mobile charging vehicle or charge the 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 specifically selected according to actual needs; the charging end of the battery has charging and discharging functions.

[0020] The specific connection mode of the n mobile charging vehicles is that 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 the n mobile charging vehicles are connected in sequence in the above manner. It can be understood that the charging gun of the last mobile charging vehicle is in an idle state, that is, a suspended state. It should be noted that the return charging port and the charging gun of each mobile charging vehicle are connected by a total conductor, and thus the n mobile charging vehicles are in a parallel connection relationship.

[0021] The multi-mobile charging vehicle parallel reverse feedback method can include the following steps: S100, if the charging gun connected to the return charging port of the current mobile charging vehicle is the charging gun of the charging pile, a first preset control instruction ZL1 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 the return charging port thereof to a preset idle state through ZL1; otherwise, step S500 is entered.

[0022] In this embodiment, the return charging port of the mobile charging vehicle has a communication function and can obtain device information of the device connected thereto, so as to determine whether the charging gun connected to the return charging port of the current mobile charging vehicle is the charging gun of the charging pile through the obtained device information; if the charging gun connected to the return charging port of the current mobile charging vehicle is the charging gun of the charging pile, it indicates that the current mobile charging vehicle is the first mobile charging vehicle; ZL1 is used to set the state of the corresponding return charging port to an idle state; the idle state can be understood as a state of not being inserted into the charging gun.

[0023] S200, control S1 of the current mobile charging vehicle to be closed, and control S2 of the current mobile charging vehicle to be disconnected.

[0024] In this embodiment, the order of reverse feedback of the mobile charging vehicle is to first feed the mobile charging vehicle connected to the charging pile; if the charging gun connected to the return charging port of the current mobile charging vehicle is the charging gun of the charging pile, S1 of the current mobile charging vehicle is controlled to be closed, and S2 of the current mobile charging vehicle is controlled to be disconnected, so that the current mobile charging vehicle is connected to the charging gun of the charging pile.

[0025] S300, obtaining the battery capacity Q now of the current mobile charging vehicle.

[0026] In this embodiment, Q now may be obtained by the detection control system of the current mobile charging vehicle; now is a percentage, for example, Q now = 90% indicates that the battery level of the current mobile charging vehicle is 90% of the full battery level.

[0027] S400, if Q now < WT, control S1 of the current mobile charging vehicle to be disconnected; and send a second preset control instruction 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 return charging port to a preset non-idle state through ZL2; wherein WT is a preset second battery level threshold.

[0028] In this embodiment, during the reverse power feedback process of the current mobile charging vehicle, Q now is obtained in real time, and if Q now < WT, it indicates that the battery level of the current mobile charging vehicle is low, and it can be considered that the feedback process has been completed, then control S1 of the current mobile charging vehicle to be disconnected, so as to disconnect the battery of the current mobile charging vehicle from the charging gun of the charging pile; the value range of WT can be 0.2-0.3.

[0029] Sending a second preset control instruction 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 return charging port to a preset non-idle state through ZL2, can connect the next mobile charging vehicle to the charging gun of the charging pile through the total conductor of the current mobile charging vehicle.

[0030] S500, obtain the battery level Q' now of the previous mobile charging vehicle connected to the current mobile charging vehicle.

[0031] In this embodiment, the current mobile charging vehicle can communicate with the previous and next mobile charging vehicles, so as to obtain the battery level of the previous mobile charging vehicle.

[0032] S600, according to Q' now , control the current mobile charging vehicle to perform reverse power feedback to the charging pile.

[0033] Further, step S600 can include the following steps: S610, if Q' now < WT, control S1 of the current mobile charging vehicle to be closed, and control S2 of the current mobile charging vehicle to be disconnected.

[0034] In the embodiment, the current mobile charging vehicle is not the first mobile charging vehicle, i.e., is not the mobile charging vehicle directly connected with the charging gun of the charging pile; at this time, it is needed to determine whether the previous mobile charging vehicle has completed reverse power feedback, if Q now WT indicates that the previous mobile charging vehicle has completed reverse power feedback, S1 of the current mobile charging vehicle is controlled to be closed, so that the current mobile charging vehicle is connected to the charging pile, and S2 of the current mobile charging vehicle is controlled to be disconnected, so as to close the external charging function of the mobile charging vehicle.

[0035] S611, the battery capacity Q of the current mobile charging vehicle is acquired. now .

[0036] S612, if Q now WT, S1 of the current mobile charging vehicle is controlled to be disconnected, and ZL2 is sent to the next mobile charging vehicle connected with the current mobile charging vehicle, so that the next mobile charging vehicle sets the state of the back charging port thereof to a preset non-idle state through ZL2.

[0037] In the process of reverse power feedback of the current mobile charging vehicle, Q now is acquired in real time, if Q now WT indicates that the battery capacity of the current mobile charging vehicle is low, it can be considered that the power feedback process has been completed, S1 of the current mobile charging vehicle is controlled to be disconnected, so that the battery of the current mobile charging vehicle is disconnected from the charging gun of the charging pile.

[0038] ZL2 is sent to the next mobile charging vehicle connected with the current mobile charging vehicle, so that the next mobile charging vehicle sets the state of the back charging port thereof to a preset non-idle state through ZL2, so as to connect the next mobile charging vehicle to the charging gun of the charging pile through the total conductor of the current mobile charging vehicle.

[0039] Further, the step S600 can further include the following steps: S630, if Q now WT, the number NUM of target mobile charging vehicles is acquired; the target mobile charging vehicle is the mobile charging vehicle connected to the current mobile charging vehicle and having a battery capacity less than WT.

[0040] S631, the weight ω of the mobile charging vehicle that has completed power feedback is determined according to NUM and n, ω=NUM / n.

[0041] S632, if ω≥ω', the state of the back charging port of the current mobile charging vehicle is set to a preset idle state, so as to stop the reverse power feedback of the current mobile charging vehicle; ω' is a preset weight threshold of the mobile charging vehicle that has completed power feedback.

[0042] In the embodiment, the n mobile charging vehicles can be used by users during the reverse feedback process, and therefore, a part of the mobile charging vehicles are not used for reverse feedback to cope with the situation that the mobile charging vehicles are suddenly needed by users during the reverse feedback process of the n mobile charging vehicles; for example, ω'≥0.3; that is, at least 30% of the mobile charging vehicles are not used for reverse feedback.

[0043] Further, the mobile charging vehicle further comprises a third switch S3; one end of the S3 is connected to the charging port of the mobile charging vehicle, and the other end is connected to the connection end of the S1 and the total wire; the mobile charging vehicle sets the state of the charging port to the preset non-idle state through the ZL2, and the method comprises the following steps: S410, the S3 of the next mobile charging vehicle is controlled to be disconnected, so that the state of the charging port of the next mobile charging vehicle is the preset idle state.

[0044] In the embodiment, after the next mobile charging vehicle controls the S3 to be disconnected, the charging gun of the previous mobile charging vehicle is still inserted into the charging port of the next mobile charging vehicle, and actually, the charging gun of the previous mobile charging vehicle has been disconnected from the charging port of the next mobile charging vehicle, and therefore, when the S3 of the next mobile charging vehicle is disconnected, the state of the charging port of the next mobile charging vehicle and the state of the charging gun of the previous mobile charging vehicle are both the preset idle state.

[0045] In the embodiment, the state of the charging port of the current mobile charging vehicle and the state of the charging gun of the previous mobile charging vehicle are changed to the preset idle state by setting the S3, and the processor of the mobile charging vehicle does not need to process complex control information, and only needs to control the on-off of the S3, so that the control of the reverse feedback sequence of the mobile charging vehicle is more simple and reliable.

[0046] Further, before the step S100, the method further comprises the following steps: S010, obtaining the current time t now .

[0047] S011, if t now is within the preset mobile charging vehicle reverse feedback time period T2, the step S100 is entered; wherein, the working mode of the charging gun of the charging pile is the reverse feedback mode within T2.

[0048] In this embodiment, the reverse power feedback time period of the mobile charging vehicle is generally the peak electricity consumption time period in the daytime, for example, T2 is 18:00-20:00 of the day; in this time period, the power grid load is relatively high, and the power grid can be reversely fed in this time period to balance the load pressure of the power grid; it should be noted that the working mode of the charging pile includes an outward discharging mode, in which the charging pile can charge the mobile charging vehicle; the working mode of the charging pile also includes a reverse power feedback mode, in which the charging pile can receive the electric energy provided by the mobile charging vehicle and reversely transmit the electric energy provided by the mobile charging vehicle to the power grid to balance the load pressure of the power grid.

[0049] The method for parallel reverse power feedback of multiple mobile charging vehicles in this embodiment, if the charging gun connected to the back charging port of the current mobile charging vehicle is the charging gun of the charging pile, sends a first preset control instruction 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 the back charging port of the next mobile charging vehicle to a preset idle state through ZL1; controls S1 of the current mobile charging vehicle to be closed and controls S2 of the current mobile charging vehicle to be disconnected, so that the current mobile charging vehicle reversely feeds the charging pile; and acquires the battery capacity of the current mobile charging vehicle, if the battery capacity of the current mobile charging vehicle is less than a preset second capacity threshold, controls S1 of the current mobile charging vehicle to be disconnected, and ends the power feeding of the current mobile charging vehicle; and sends a second preset control instruction 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 the back charging port of the next mobile charging vehicle to a preset non-idle state through ZL2; if the charging gun connected to the back charging port of the current mobile charging vehicle is not the charging gun of the charging pile, acquires the battery capacity Q of the previous mobile charging vehicle connected to the current mobile charging vehicle now , according to Q now , controls the current mobile charging vehicle to reversely feed the charging pile; thereby realizing the automatic reverse power feedback process of multiple mobile charging vehicles; since the entire reverse power feedback process of multiple mobile charging vehicles is realized automatically, the entire power feeding process is relatively simple, and does not need to be manned, and the convenience of reverse power feedback is relatively high.

[0050] In an exemplary embodiment, based on the connection mode of the n mobile charging vehicles in the above embodiment, a method for realizing automatic unattended charging of n mobile charging vehicles is provided, and specifically, the method can include the following steps: T100, acquiring the state HC of the back charging port of the current mobile charging vehicle now and the state CD of the charging gun of the current mobile charging vehicle now .

[0051] In the embodiment, whether the return port of the mobile charging vehicle is inserted into the charging gun and whether the charging gun of the mobile charging vehicle is connected to other equipment can be directly obtained by the detection control system of the mobile charging vehicle; therefore, the HC now and CD now ; when the return port is inserted into the charging gun, the corresponding state is the non-idle state, and when the return port is not inserted into the charging gun, the corresponding state is the idle state; when the charging gun of the mobile charging vehicle is inserted into the next mobile charging vehicle, the corresponding state is the non-idle state, and when the charging gun of the mobile charging vehicle is suspended, the corresponding state is the idle state.

[0052] It can be understood that the state of the charging gun of the current mobile charging vehicle is the same as the state of the return port of the next connected mobile charging vehicle.

[0053] T200, if HC now is the preset non-idle state and CD now is the preset idle state, the battery capacity Q now of the current mobile charging vehicle is obtained.

[0054] In the embodiment, if HC now is the preset non-idle state and CD now is the preset idle state, it indicates that the current mobile charging vehicle is the last mobile charging vehicle, at this time, the detection control system of the current mobile charging vehicle can obtain the battery capacity of the current mobile charging vehicle.

[0055] T300, if Q now is less than Q', S1 of the current mobile charging vehicle is controlled to be closed and S2 of the current mobile charging vehicle is controlled to be disconnected; wherein Q' is a preset first capacity threshold.

[0056] In the embodiment, first, it is judged whether the battery capacity of the current mobile charging vehicle is less than the preset first capacity threshold Q', for example, Q' can be set to 90%; if Q now is less than Q', it indicates that the battery capacity of the current mobile charging vehicle meets the condition of continuing to charge, S1 of the current mobile charging vehicle is controlled to be closed and S2 of the current mobile charging vehicle is controlled to be disconnected, so that the charging pile charges the last mobile charging vehicle; and the battery capacity of the current mobile charging vehicle is continuously obtained until the battery is fully charged.

[0057] T400, if Q now is greater than or equal to Q', S1 of the current mobile charging vehicle is controlled to be disconnected and S2 of the current mobile charging vehicle is controlled to be closed; and step T500 is entered.

[0058] In the embodiment, if Q now≥ Q', indicating that the current mobile charging vehicle has a high battery level and does not meet the condition for continuing charging, the S1 of the current mobile charging vehicle is controlled to be disconnected, the S2 of the current mobile charging vehicle is controlled to be connected, so that the current mobile charging vehicle is disconnected from the charging pile and the charging is stopped.

[0059] T500, setting the state of the return charging port of the current mobile charging vehicle to a preset idle state, and setting the state of the charging gun of the previous mobile charging vehicle to a preset idle state.

[0060] In the embodiment, after the current mobile charging vehicle is fully charged, the state of the return charging port of the current mobile charging vehicle 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 with the current mobile charging vehicle, i.e., the last mobile charging vehicle, is equivalent to the last mobile charging vehicle, thereby being able to enter step T100 to continue to perform the above steps for charging.

[0061] If the last mobile charging vehicle is disconnected from the previous mobile charging vehicle by the user when the battery of the last mobile charging vehicle is not fully charged, the previous mobile charging vehicle becomes the last mobile charging vehicle, thereby being able to perform step T100 for charging.

[0062] The parallel charging method of the plurality of mobile charging vehicles in the embodiment is that the charging gun of any mobile charging vehicle of the n mobile charging vehicles is connected with the return charging port of the next mobile charging vehicle, and the return charging port of the first mobile charging vehicle is connected with the charging gun of the charging pile; the state HC of the return charging port of the current mobile charging vehicle is obtained now and the state CD of the charging gun of the current mobile charging vehicle is obtained now ; whether the current mobile charging vehicle is the mobile charging vehicle currently in need of charging is determined according to HC now and CD now ; if the current mobile charging vehicle is the mobile charging vehicle in need of charging, the battery level Q of the current mobile charging vehicle is obtained now ; if Q now < Q', the S1 is controlled to be connected and the S2 is controlled to be disconnected; thereby the current mobile charging vehicle is charged; if Q now ≥ Q', indicating that the charging is completed, the S1 is controlled to be disconnected and the S2 is controlled to be connected; thereby the charging can be realized from the last connected mobile charging vehicle to the front one by one, the whole charging process is relatively simple, and a dedicated person is not needed to be on duty, which is good in convenience.

[0063] In addition, when the user uses the mobile charging vehicle, the last connected mobile charging vehicle can be used first, and the battery of the last connected mobile charging vehicle has the largest power, which meets the use demand of the actual scene; and the last connected mobile charging vehicle is only connected with the charging gun of the previous mobile charging vehicle through the self-recharging port, and after the connection is disconnected, it does not affect the remaining mobile charging vehicle to continue charging, further improving the convenience.

[0064] Further, after step T100 and before step T200, the method comprises the following steps: T110, if HC now and CD now are both preset non-idle states, control S1 and S2 of the current mobile charging vehicle to be disconnected.

[0065] In this embodiment, if HC now and CD now are both preset non-idle states, it indicates that the recharging port of the current mobile charging vehicle is inserted with a charging gun, and the charging gun of the current mobile charging vehicle is also inserted in the recharging port of another mobile charging vehicle, it can be determined that the current mobile charging vehicle is not the last mobile charging vehicle; then, S1 and S2 of the current mobile charging vehicle should be controlled to be disconnected, so that the current mobile charging vehicle is in the state of queuing for charging.

[0066] T120, if HC now is a preset idle state, control S1 of the current mobile charging vehicle to be disconnected, and control S2 of the current mobile charging vehicle to be closed.

[0067] In this embodiment, if HC now is a preset idle state, it indicates that the recharging port of the current mobile charging vehicle is not inserted with a charging gun, then control S1 of the current mobile charging vehicle to be disconnected, and control S2 of the current mobile charging vehicle to be closed, so that the current mobile charging vehicle can charge the external new energy vehicle at any time.

[0068] Further, before step T100, the method can comprise the following steps: T010, acquiring the current time t now .

[0069] T011, if t now is within a preset mobile charging vehicle charging time period T1, enter step T100; wherein the working mode of the charging gun of the charging pile within T1 is the outward discharging mode.

[0070] In this embodiment, the power supplement time period of the mobile charging vehicle is generally at night, for example, T1 is 22:00 of the current day to 6:00 of the next day; during this time period, the mobile charging vehicle is used by the user less frequently, and it is suitable to supplement power during this time period; it should be noted that the working mode of the charging pile includes a power output mode, in which the charging pile can charge the mobile charging vehicle; the working mode of the charging pile also includes a reverse power feedback mode, in which the charging pile can receive the power provided by the mobile charging vehicle and reversely transmit the power provided by the mobile charging vehicle to the power grid to balance the load pressure of the power grid.

[0071] Further, the mobile charging vehicle further comprises a third switch S3; one end of S3 is connected to the back charging port of the mobile charging vehicle, and the other end is connected to the connection end of S1 and the total conductor; S3 can be a relay or a contactor; step T500 can comprise the following steps: T510, control S3 of the current mobile charging vehicle to be disconnected, so that the state of the back charging port of the current mobile charging vehicle and the state of the charging gun of the previous mobile charging vehicle are both in a preset idle state.

[0072] In this embodiment, after S3 is controlled to be disconnected, although the charging gun of the previous mobile charging vehicle is still inserted into the back charging port of the current mobile charging vehicle, in fact, the charging gun of the previous mobile charging vehicle has been disconnected from the back charging port of the current mobile charging vehicle, therefore, under the condition that S3 is disconnected, the state of the back charging port of the current mobile charging vehicle and the state of the charging gun of the previous mobile charging vehicle are both in a preset idle state.

[0073] In this embodiment, by setting S3, the state of the back charging port of the current mobile charging vehicle and the state of the charging gun of the previous mobile charging vehicle are both changed to a preset idle state, without the processor of the mobile charging vehicle processing complex control information, only the on-off of S3 needs to be controlled, and communication with the adjacent connected mobile charging vehicle is not required, so that the control of the charging sequence of the mobile charging vehicle is more simple and reliable.

[0074] In addition, by the above method, even in the case that the last mobile charging vehicle is fully charged and not disconnected by the user, the previous mobile charging vehicle can also be automatically switched to be charged, realizing unattended charging.

[0075] Further, 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.

[0076] Further, Q' is determined according to the current t now and the preset mobile charging vehicle charging time period T1, specifically, it can comprise the following steps: T310, acquiring the current time t now.

[0077] T320, if t now If T1 is within the time interval, the starting time t1 and the ending time t2 corresponding to T1 are obtained.

[0078] T330, obtaining the time interval TA with t now and the time interval TB with t now and the time interval TB with t

[0079] T340, obtaining the target time interval TC=MIN(TA, TB) and the preset range FQ=[FQ1, FQ2] corresponding to Q'; wherein MIN() is a preset minimum value function; FQ1 is a minimum first electric quantity threshold corresponding to Q', and FQ2 is a maximum first electric quantity threshold corresponding to Q'.

[0080] In this embodiment, for example, FQ1 can be 0.85, and FQ2 can be 0.95.

[0081] T350, determining Q'=FQ1+TC×(FQ2-FQ1) / (0.5×(t2-t1)) according to TC, T1 and FQ.

[0082] 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 car is used with the lowest probability, at this time, Q' is set to be larger, so that the battery electric quantity of each mobile charging car when fully charged is higher; and the time interval from t1 or t2 is smaller, the probability of the mobile charging car being used is larger, at this time, Q' is set to be smaller, so that the speed of the mobile charging car being fully charged is improved, thereby providing a larger number of mobile charging cars that are fully charged for the user. now The time interval from t1 or t2 is smaller, the probability of the mobile charging car being used is larger, at this time, Q' is set to be smaller, so that the speed of the mobile charging car being fully charged is improved, thereby providing a larger number of mobile charging cars that are fully charged for the user.
