[0022] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are only some, but not all, of the embodiments of the present application. Components of the embodiments of the present application described and illustrated in the accompanying drawings here can be arranged and designed in a variety of different configurations. Therefore, the detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application claimed, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, every other embodiment obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0023] In the prior art, with the rapid development of new energy vehicles, the number of users is increasing continuously, while the number of charging piles is far from enough to match the number of new energy vehicles. When it is necessary to charge when driving to the service area, there are a lot of queuing at this time, which will cause an unfriendly experience for users who urgently need to charge quickly.

[0024] In view of the above problems, the embodiments of the present application provide a mobile charging vehicle, which can place at least one battery pack on the movable carriage of the mobile charging vehicle, set the high-voltage box between the charging module and the battery pack, set the industrial control computer between the charging module and the charging gun, and set the charging gun outside the movable carriage. The charging gun obtains the charging conditions of the charging vehicle by connecting to the charging vehicle and sends them to the industrial control computer. The industrial control computer sends the charging conditions to the charging module. The charging module obtains the power of the battery pack through the high-voltage box and delivers the electric energy of the battery pack to the charging gun through the industrial control computer according to the charging conditions, solving the technical problem that the fixed position of the charging pile in the prior art may cause road congestion, and achieving the technical effect of flexibly adjusting the position of the charging pile according to the position of the vehicle. Furthermore, the present application controls a movable charging vehicle to drive near the vehicle that needs to be charged, so that there is no need for the vehicle to be charged to queue beside the charging pile, and the charging scenarios are increased, as follows:

[0025] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a mobile charging vehicle provided by an embodiment of the present application. As Figure 1As shown in the figure, the mobile charging vehicle provided by the embodiment of the present application includes a movable carriage (not shown in the figure); a charging gun 101, which is placed outside the movable carriage and is used to connect to the charging vehicle; at least one battery pack 102, which is placed on the movable carriage; a high-voltage box 103, one end of the high-voltage box is connected to the at least one battery pack; a charging module 104, the first power input end of the charging module is connected to the other end of the high-voltage box; an industrial control computer 105, the second power input end of the industrial control computer is connected to the first power output end of the charging module, and the second power output end of the industrial control computer is connected to the charging gun.

[0026] Among them, the industrial control computer is used to obtain the charging conditions of the charging vehicle through the charging gun and send the charging conditions to the charging module. The high-voltage box is used to transmit the electric energy of the at least one battery pack to the charging module. The charging module is used to adjust the electric energy output from the power output end so that the electric energy output by the charging gun meets the charging conditions of the charging vehicle.

[0027] Among them, after the charging gun is connected to the charging vehicle, the connection interface between the charging gun and the charging vehicle is also synchronously connected to the charging controller. Furthermore, the charging controller determines whether the charging gun is connected to the charging vehicle through the connection interface between the charging gun and the charging vehicle, and obtains the charging conditions of the charging vehicle, so that the charging controller can send the charging conditions to the charging module, and the charging module adjusts the electric energy output from the power output end.

[0028] That is to say, after the charging gun is connected to the charging port of the charging vehicle, the charging conditions of the charging vehicle are fed back to the charging controller through the common connection end of the charging gun, the charging vehicle and the charging controller. The charging conditions include the charging voltage, charging current, etc. preset by the charging vehicle, which are the conditions required for the charging vehicle to charge.

[0029] Among them, the industrial control computer includes a charging gun communication interface for the charging gun and a charging communication interface for the charging module. The charging gun communication interface of the industrial control computer is connected to the communication interface of the charging gun, that is, connected to the charging vehicle, so that the industrial control computer can obtain the charging conditions of the charging vehicle through the charging gun. The charging communication interface of the industrial control computer is connected to the communication interface of the charging module, so that the industrial control computer can send the charging conditions to the charging module through the charging communication interface.

[0030] Moreover, the high-voltage box leads out the electric energy of the at least one battery pack to the charging module. When the charging module determines the charging conditions of the charging vehicle, the charging module changes the electric energy output from the power output end according to the charging conditions of the charging vehicle. Thus, the electric energy output by the charging gun also changes.

[0031] Please refer to Figure 2 , Figure 2The circuit diagram of a mobile charging vehicle provided by an embodiment of this application. As Figure 2 shown, the industrial control computer includes a charging controller U1. Among them, the first charging gun communication interface (P6_2 pin) of the charging controller is connected to the connection recognition interface (CC1 pin) of the charging gun 101, and is used to determine whether the charging gun is connected to the charging vehicle. The second charging gun communication interface (P8_1 pin and P8_3 pin) of the charging controller is connected to the communication interface (S+ pin and S- pin) of the charging gun, and is used to obtain the charging conditions when the charging gun is connected to the charging vehicle. Among them, the P8_2 pin of the charging controller is left empty.

[0032] That is to say, at least an identification pin co-terminal with the CC1 pin and communication pins co-terminal with the S+ pin and S- pin are correspondingly arranged on the charging port of the charging vehicle. The identification pin of the charging vehicle can output a high-level signal. Furthermore, the first charging gun communication interface of the charging controller can receive the high-level signal through the connection recognition interface (CC1 pin) of the charging gun 101 to determine that the charging gun is connected to the charging vehicle. The communication pins of the charging vehicle send the charging conditions to the S+ pin and S- pin. Furthermore, the second charging gun communication interface (P8_1 pin and P8_3 pin) of the charging controller obtains the charging conditions through the communication interface (S+ pin and S- pin) of the charging gun.

[0033] Among them, the temperature detection interfaces (T1+ pin, T1- pin, T2+ pin, and T2- pin) of the charging gun are connected to the temperature detection interfaces (P8_5 pin, P8_6 pin, P8_7 pin, and P8_8 pin) of the charging controller, so that the charging controller can collect the temperature at the connection between the charging gun and the charging vehicle. Figure 2 In, the T1- pin and T2- pin of the charging gun are integrated into a T1-T2- pin.

[0034] The charging gun also includes a grounding interface PE and an external power supply interface (DC+ pin and DC- pin). The grounding interface PE of the charging gun is connected to the P6_1 pin of the charging controller to provide a grounding terminal for the charging gun. The external power supply interface of the charging gun is used to connect to the power input terminal of the charging port of the charging vehicle to output electric energy to the charging vehicle. The charging gun also includes a PIN1 pin and a PIN2 pin left empty.

[0035] The industrial control computer further includes a gun locking controller U2. The gun locking receiving interface (DI- pin) of the gun locking controller is connected to the gun locking control interface (P4_6 pin) of the charging controller for receiving the switch locking control signal sent by the charging controller. The gun locking sending interfaces (LOCKA pin and LOCKB pin) of the gun locking controller are connected to the switch control interfaces (EL+ pin and EL- pin) of the charging gun for controlling the charging gun to unlock or lock according to the switch locking control signal. Further, after the charging vehicle finishes charging, the charging gun is controlled to unlock so that the charging gun can be unplugged from the charging vehicle; during the charging process of the charging vehicle, the charging gun is controlled to lock to prevent the charging gun being charged from being unplugged from the charging vehicle.

[0036] Exemplarily, when the charging controller determines through the first charging gun communication interface (P6_2 pin) that the charging gun is connected to the charging port of the charging vehicle and the charging controller receives the charging condition of the charging vehicle, the charging controller sends a locking control signal to the gun locking receiving interface (DI- pin) of the gun locking controller through the gun locking control interface (P4_6 pin). Further, the gun locking controller controls the gun locking sending interfaces (LOCKA pin and LOCKB pin) to send a locking signal to the switch control interfaces (EL+ pin and EL- pin) of the charging gun according to the locking control signal to control that the charging gun and the charging vehicle cannot be separated in the locked state, which can prevent the charging gun from detaching from the charging vehicle during the charging process.

[0037] Exemplarily, when the charging controller confirms that the power output to the charging vehicle meets the charging requirements of the charging vehicle and / or the charging vehicle feeds back to the charging controller through the charging gun that the current vehicle battery is fully charged, the charging controller sends an unlocking control signal to the gun locking receiving interface (DI- pin) of the gun locking controller through the gun locking control interface (P4_6 pin). Further, the gun locking controller controls the gun locking sending interfaces (LOCKA pin and LOCKB pin) to send an unlocking signal to the switch control interfaces (EL+ pin and EL- pin) of the charging gun according to the unlocking control signal to unlock the charging gun, and the user can take down the charging gun from the charging vehicle.

[0038] Exemplarily, the operating voltage of the charging controller is 12V DC, and it adopts the PN-OS embedded operating system. The charging controller includes a flash memory FLASH and a random access memory RAM. The main control board integrates multiple inputs, outputs, and analog quantity acquisitions, and includes at least 9 communication interfaces, 2 insulation detections, and 2 control guides. All the outputs and inputs on the main board are active ports. The communication interfaces include the S+ and S- pins for communicating with the charging gun, the power meter communication interface (P11_7 and P11_8 pins) for communicating with the power meter, the interactive screen communication interface (P10_6 and P10_7 pins) for communicating with the interactive screen, and the P9_4 and P9_6 pins for communicating with the charging module.

[0039] Specifically, the industrial control computer further includes a power meter U3 and an interactive screen T. Among them, the current acquisition interface (I+ and I- pins) and the voltage acquisition interface (U1+ and U1- pins) of the power meter are respectively connected between the charging gun and the industrial control computer to collect the vehicle charging current and vehicle charging voltage flowing into the charging gun, so as to determine the vehicle charging power consumption. The communication interface (DA and DB pins) of the power meter is connected to the power meter communication interface (P11_7 and P11_8 pins) of the charging controller, so that the charging controller can receive the vehicle charging power consumption. The interactive screen communication interface (P10_6 and P10_7 pins) of the charging controller is connected to the interactive screen, so that the interactive screen can display the vehicle charging power consumption.

[0040] Among them, the second power output terminals (DC / DC OUT- and DC / DC OUT+) of the industrial control computer are connected to the charging gun, and the current acquisition interface (I+ and I- pins) and the voltage acquisition interface (U1+ and U1- pins) are connected to the power transmission line between the second power output terminal and the charging gun to obtain the voltage and current flowing into the charging gun. Exemplarily, the vehicle charging power consumption (kWh) is calculated by multiplying the voltage, current, and charging time and then dividing by 1000.

[0041] Among them, the power meter includes a Hall sensor HS. The Hall sensor includes a hollow ring in the middle. The positive busbar for transmitting power between the charging gun and the second power output terminal of the industrial control computer passes through the ring. If there is current flowing through, the generated magnetic field will cause the Hall sensor to generate a potential difference. Furthermore, the Hall sensor can calculate the current through the potential difference, so that the current acquisition interface of the power meter can obtain the current flowing into the charging gun.

[0042] Furthermore, the electricity meter sends the vehicle charging power to the electricity meter communication interface (P11_7 pin and P11_8 pin) of the charging controller through the communication interface (DA pin and DB pin), and the charging controller then sends the vehicle charging power to the TX pin and RX pin of the interactive screen through the interactive screen communication interface (P10_6 pin and P10_7 pin), so that the interactive screen can display the vehicle charging power.

[0043] Among them, the electricity meter also includes a first power interface (24V+ pin and 24V- pin), as well as a second power interface (12V+ pin and 12V- pin) and a ground interface G for powering the Hall sensor, so as to provide electrical energy to the Hall sensor.

[0044] Among them, the interactive screen also includes an interactive screen power interface and an interactive screen ground interface. The interactive screen power interface of the interactive screen is connected to the P10_8 pin of the charging controller, so that the charging controller provides 12V power to the interactive screen. The interactive screen ground interface of the interactive screen is connected to the P10_5 pin of the charging controller, so that the charging controller provides a ground terminal to the interactive screen to realize power supply to the interactive screen.

[0045] The mobile charging vehicle also includes a communication module (not shown in the figure), and the charging controller is configured to: receive a charging request for the charging vehicle through the communication module or the interactive screen.

[0046] Among them, the communication module is used to provide a communication network for the mobile charging vehicle to obtain a charging request for the charging vehicle sent by the cloud or the client program corresponding to the mobile charging vehicle. That is to say, the user can directly walk to the mobile charging vehicle and issue a charging request by operating the interactive screen, or the user can download the client program corresponding to the mobile charging vehicle on the user terminal and issue a charging request by operating the operation page of the client program.

[0047] Exemplarily, the interactive screen or the operation page of the client program displays the current position and current power of the mobile charging vehicle, so as to facilitate the user to confirm whether the current position of the mobile charging vehicle is too far from the charging vehicle and whether the current power meets the electrical energy required by the charging vehicle. Thus, by the interactive screen or the operation page, it is informed to the user that the current power meets the electrical energy required by the charging vehicle. If the user believes that the current position of the mobile charging vehicle is not too far from the charging vehicle, the user can drag the mobile charging vehicle to the charging vehicle.

[0048] Furthermore, when the interactive screen or the operation page receives a charging request for the charging vehicle, the interactive screen notifies the charging controller of the charging request, or the server corresponding to the client program notifies the charging controller of the charging request through the communication module, so that the mobile charging vehicle can clarify the charging request. Exemplarily, the charging request includes the charging power required by the charging vehicle.

[0049] Furthermore, the power meter of the mobile charging vehicle informs the interactive screen of the charging power through the charging controller, so that the charging power detected by the power meter can be displayed on the interactive screen. After the power meter of the mobile charging vehicle informs the charging controller that the required charging power has been charged to the charging vehicle, a prompt message indicating that the charging is completed is displayed through the interactive screen or the operation page. Furthermore, the user can pull out the charging gun by himself, or a robotic arm is set on the mobile charging vehicle, and the charging gun is pulled out by the robotic arm when it is determined that the charging is completed.

[0050] Exemplarily, the mobile charging vehicle can also achieve autonomous driving. The mobile charging vehicle further includes a driving module, a vehicle control module (VCU, Vehicle Control Unit), and an engine management module EMS. The driving module is connected to the vehicle control module, and the vehicle control module is connected to the engine management module EMS. The engine management module EMS is connected to the charging controller through an RS485 communication module. The communication module providing the communication network of the mobile charging vehicle described above can be integrated in the EMS. The charging request sent by the user through the interactive screen or the operation page of the client program further includes the position of the charging vehicle. Furthermore, after the communication module obtains the charging request, the EMS plans the driving route of the mobile charging vehicle based on the position of the charging vehicle and the current position of the mobile charging vehicle, and the EMS sends a driving instruction to the VCU to enable the VCU to control the motor corresponding to the driving module to start to drive the mobile charging vehicle to move. The VCU can also transmit the motor speed, induction radar information, etc. of the mobile charging vehicle to the EMS to enable the EMS to monitor the driving process. The EMS can control when the motor turns and how much driving ability is output through the VCU.

[0051] Exemplarily, the driving information determined by the EMS and the information such as the motor speed and induction radar information collected by the VCU can be transmitted to the interactive screen through the charging controller, so that the motor speed, induction radar information, etc. can be displayed on the interactive screen. The mobile charging vehicle further includes an RS485 communication module. The engine management module EMS and the charging controller communicate through the RS485 communication module. The 485A pin of the engine management module EMS is connected to the 485A pin of the RS485 communication module, and the 485B pin of the engine management module EMS is connected to the 485B pin of the RS485 communication module. The EMS_TX pin of the RS485 communication module is connected to the P11_5 pin of the charging controller, and the EMS_TX pin of the RS485 communication module is connected to the P11_6 pin of the charging controller. The engine management module EMS and the charging controller can also communicate through CAN, which is not limited in this application. The engine management module EMS further includes 12V+ pin and 12V- pin for obtaining the electric energy required by the EMS.

[0052] The mobile charging vehicle further includes a frequency converter and a transformer. One end of the frequency converter is connected to the heat management power output end of the high-voltage box, the other end of the frequency converter is connected to one end of the transformer, and the other end of the transformer is used to output vehicle electrical energy for the mobile charging vehicle.

[0053] The frequency converter is used to convert the direct current output from the heat management power output end (TMS+ pin and TMS- pin) of the high-voltage box into alternating current, and the transformer is used to condition the voltage of the alternating current so that the voltage of the alternating current adapts to the operating voltage of the liquid cooler.

[0054] The mobile charging vehicle further includes a battery charger, a vehicle battery, and a voltage regulator. One end of the battery charger is connected to the other end of the transformer, the other end of the battery charger is respectively connected to one end of the vehicle battery and the voltage regulator, and the other end of the voltage regulator is used to output vehicle electrical energy for the mobile charging vehicle, and the vehicle electrical energy supplies power to each electrical module in the mobile charging vehicle.

[0055] Exemplarily, the other end of the transformer outputs 220V alternating current. The voltage regulator includes a first DC-DC voltage regulator, a second DC-DC voltage regulator, and a third DC-DC voltage regulator. One end of the first DC-DC voltage regulator is connected to the battery charger, the other end of the first DC-DC voltage regulator is connected to one end of the second DC-DC voltage regulator and one end of the third DC-DC voltage regulator, and the other end of the first DC-DC voltage regulator outputs a first preset power supply of 24V, and the other ends of the second DC-DC voltage regulator and the third DC-DC voltage regulator both output a second preset power supply of 12V. That is, the 220V alternating current is converted into 48V direct current required by the vehicle battery through the battery charger, the 48V direct current is converted into 24V direct current through the first DC-DC voltage regulator DC / DC1, and the 24V direct current is converted into 12V direct current through both the second DC-DC voltage regulator DC / DC2 and the third DC-DC voltage regulator DC / DC3. Thus, electrical energy is provided to each module of the mobile charging vehicle.

[0056] The power provided by a single DC-DC voltage regulator is limited. Furthermore, the second DC-DC voltage regulator and the third DC-DC voltage regulator are required to share the load power consumption of the mobile charging vehicle.

[0057] The mobile charging vehicle further includes a liquid cooler. The liquid cooler is arranged in contact with the at least one battery pack 102 and is used to adjust the temperature of the at least one battery pack. The power supply end of the liquid cooler is connected to the other end of the transformer.

[0058] That is to say, the transformer supplies power to the liquid cooler to enable the liquid cooler to start working, regulate the temperature of at least one battery pack, and prevent the temperature of at least one battery pack from overheating. Exemplarily, when a charging request is received through the interactive screen or communication module, if the BMS of the battery pack itself detects no abnormality, the relay in the high-voltage box is closed so that at least one battery pack outputs electrical energy through the BDU OUT+ pin and BDU OUT- pin of the high-voltage box. Moreover, the TMS+ pin and TMS- pin of the high-voltage box synchronously output electrical energy to supply power to the liquid cooler through the frequency converter and the transformer, so that the liquid cooler starts synchronously during the discharge process of the battery pack to cool the battery pack.

[0059] That is to say, the BMS module is integrated inside the battery pack, which can detect the voltage and temperature of each single battery cell in the battery pack to achieve BMS detection of the battery pack and clarify whether there is a fault in the battery pack itself. The BMS module of the battery pack can send the collected information to the control module of the high-voltage box through CAN communication, so that the control module can clarify each detection data of the battery pack. Furthermore, after the BMS module of the battery pack determines that the battery pack has no abnormality, it notifies the control module of the high-voltage box that the battery pack is normal, so that the high-voltage box can output the electrical energy of the battery pack to the charging module or transmit external electrical energy to the battery pack.

[0060] Among them, the high-voltage box also includes power pins (24V+ pin and 24V- pin) for connecting the 24V direct current output by the first DC / DC converter DC / DC1 to supply power to the control module of the high-voltage box.

[0061] Moreover, an AC contactor is provided between the high-voltage box and the charging module. The BDU OUT+ pin and the BDU OUT- pin of the high-voltage box output electric energy to the BDU OUT+ pin and the BDU OUT- pin of the AC contactor. The DC / DC IN- pin and the DC / DC IN+ pin of the AC contactor are connected to the V+ pin and the V- pin of the charging module, so that the electric energy of the battery pack is transmitted to the charging module through the high-voltage box and the AC contactor. Based on this, when the charging controller confirms that the charging gun is connected to the charging vehicle, the charging conditions of the charging vehicle are informed to the CAN communication interface (CANL pin and CANH pin) of the charging module through the P9_4 pin and the P9_6 pin of the charging controller, and the P9_5 pin of the charging controller is left empty. Moreover, the charging controller controls the relays K1 and K2 on the second power output terminals (DC / DC OUT- and DC / DC OUT+) of the industrial computer to close through the P2_6 pin, and the charging controller controls the AC contactor to close through the P2_7 pin, so that the BDU OUT+ pin and the BDU OUT- pin of the high-voltage box are connected to the V+ pin and the V- pin of the charging module. Furthermore, the electric energy of the battery pack is input into the charging module through the high-voltage box, and the charging module then outputs to the charging gun, that is, the second power output terminal of the industrial computer supplies power to the charging gun.

[0062] Among them, the AC contactor, the relay K1, and the relay K2 are all connected to the 12V+ and 12V- power supplies, so that the AC contactor, the relay K1, and the relay K2 can receive the control signals issued by the charging controller to perform corresponding closing or opening actions.

[0063] As Figure 2 shown, the mobile charging vehicle further includes at least one of the following warning lights: a power light L1, which is connected to the power light control interface of the charging controller; a fault light L2, which is connected to the fault light control interface of the charging controller; an operation light L3, which is connected to the operation light control interface of the charging controller; wherein, the charging controller is configured to: control the working state of the corresponding warning light through the warning light control interface according to the operation state of the mobile charging vehicle.

[0064] Exemplarily, after the charging controller is powered on, if it is determined that a charging vehicle is connected through the CC1 pin of the charging gun, but the charging conditions for the charging vehicle are not received, it is considered that the operating state of the mobile charging vehicle is in the standby state at this time, and then the power light is controlled to turn on through the power light control interface of the charging controller. After the charging controller is powered on, if it is confirmed that it is connected to the charging vehicle through the CC1 pin of the charging gun, and the charging conditions of the charging vehicle are received, and the charging controller controls the charging module to output electric energy, it is considered that the operating state of the mobile charging vehicle is in the running state, and then the running light is controlled to turn on through the running light control interface of the charging controller. During the charging process, if the charging gun is disconnected from the S+, S-, A+, and A- pins of the charging controller, or the emergency stop control switch of the mobile charging vehicle is pressed, or the current discharge voltage and current are not within the charging conditions output by the charging controller to the charging module, it is considered that the operating state of the mobile charging vehicle is in an abnormal state, and then the fault light control interface of the charging controller controls the fault light to turn on.

[0065] As Figure 2 shown, the mobile charging vehicle further includes an emergency stop light L0. One end of the emergency stop light is connected to the emergency stop control interface (P2_9 pin) of the charging controller, the other end of the emergency stop light is connected to one end of an emergency stop control switch (not shown in the figure), and the other end of the emergency stop control switch is connected to a second preset power supply. Furthermore, if the user discovers an abnormality during the charging process, the user closes the emergency stop control switch, the emergency stop light lights up when powered on, and the P2_9 pin receives a high-level signal. Furthermore, the charging controller learns that there is an abnormal situation, and then the charging controller controls the relays K1 and K2 and the AC contactor to disconnect, and instructs the charging module to stop outputting electric energy to end the charging.

[0066] Exemplarily, as Figure 2 shown, one end of each indicator light is connected to the second preset power supply, and the other end of the indicator light is connected to the control interface of the corresponding indicator light of the charging controller. Furthermore, when the charging controller determines that the operating state of the mobile charging vehicle is in the normal operating state, it controls the running light to work and the fault light to go out. When the charging controller determines that the operating state of the mobile charging vehicle is in the fault state, it controls the fault light to work and the running light to go out.

[0067] The mobile charging vehicle further includes a charging socket J. One end of the charging socket is used to connect to an external power supply, the other end of the charging socket is used to connect to the charging end (C+ pin and C- pin) of the high-voltage box, and the charging end of the high-voltage box is connected to one end of the high-voltage box (PACK+ pin and PACK- pin) to connect at least one battery pack, so that the electric energy of the external power supply is transmitted to the at least one battery pack through the high-voltage box.

[0068] That is to say, when the battery pack needs to be charged, one end of the charging base is connected to an external power source. Further, the electric energy of the external power source flows into the battery pack through the charging terminals (C+ pin and C- pin) of the high-voltage box, thereby realizing the charging of the battery pack.

[0069] Exemplarily, the BMS module of the battery pack notifies the control module inside the high-voltage box that the battery pack has insufficient power and needs to be charged. And the control modules of the charging base and the high-voltage box, like the charging gun and the charging controller, are equipped with CC1 pin, S+ pin, S- pin, A+ pin, A- pin, etc. for communication with the charging base. When the charging base is connected to the external power source, the CC1 pin of the control module knows that the charging base is connected to the external power source. The A+ pin and A- pin of the control module control the charging base to lock, so as to lock the charging base and the external power source. And the BMS module of the battery pack sends the voltage and current information required for charging to the external power source through the S+ pin and S- pin of the control module, so that the external power source outputs electric energy corresponding to the charging voltage and current of the battery pack. Further, the external power source charges the battery pack through the charging base.

[0070] Please refer to Figure 3 , Figure 3 which is a schematic diagram of a mobile charging vehicle provided by an embodiment of the present application.

[0071] Exemplarily, a groove is provided on the movable carriage of the mobile charging vehicle, and a platform is placed on the upper part of the groove. Among them, two battery packs are sequentially placed in the groove of the movable carriage, a liquid cooler is placed on the battery packs, an industrial computer is placed on the side of the battery packs through fixed feet, the upper part of the liquid cooler is the placement platform, and a charging module and a high-voltage box are placed on the placement platform. Exemplarily, in order to make the appearance beautiful, a charging vehicle shell can also be provided outside the movable carriage so that the charging gun, the charging base, and the moving handle of the movable carriage are all placed outside the charging vehicle shell.

[0072] Furthermore, compared with the existing fixed charging piles, the present application increases the charging places, provides a movable charging pile for vehicles in urgent need of charging, avoids waiting for the fixed charging pile and the lane congestion problem caused by waiting for the fixed charging pile, and realizes the charging conditions for new energy vehicles adapting to voltages from 200V to 1000V or even higher through the charging module.
