[0022] The present invention is described below based on embodiments, but the invention is not limited to these embodiments. In the detailed description of the invention below, certain specific details are described in detail. Those skilled in the art will fully understand the invention even without these details. To avoid obscuring the essence of the invention, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0023] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0024] Unless the context explicitly requires it, words such as "including" or "contains" throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to".

[0025] In the description of this invention, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0026] One aspect of this invention relates to a charging system 10 that can be used to charge batteries for electric bicycles, electric motorcycles, etc. (See also...) Figure 1 In this embodiment of the invention, the charging system 10 can be mounted on a mobile vehicle 40, thereby allowing the charging system 10 to be conveniently transported to the desired location as needed. The mobile vehicle 40 can be a van, flatbed truck, rail vehicle, manual vehicle, etc., and can be selected according to the needs of the usage scenario.

[0027] Reference Figures 1-3The charging system 10 is provided with a plurality of charging compartments 11, each capable of accommodating one or more batteries. Each charging compartment 11 has a charger 12 that can connect to the batteries placed within the compartment to charge them. In some embodiments, the charging system 10 may be partially or entirely implemented as a cabinet structure to facilitate installation on a mobile vehicle 40 and ensure safety and stability during transport.

[0028] In this embodiment, the charging system 10 includes a power interface 15, the structure of which is compatible with the charging gun on the DC charging pile 20 for charging electric vehicles, so that it can be plugged into the charging gun of the DC charging pile 20. After the charging system 10 establishes a connection with the DC charging pile 20, it can supply power to the charger 12 in the charging compartment 11 through the DC charging pile 20 to charge the battery connected to the charger 12.

[0029] In some embodiments, the charging compartment 11 is further provided with a battery status acquisition module 19, used to acquire battery parameters of the battery in the charging compartment 11. These battery parameters may include, for example, battery presence status, battery state of charge (SOC), charging current, and charging voltage. The battery presence status indicates whether a battery correctly connected to the charger 12 is placed in the charging compartment 11. Optionally, the battery status acquisition module 19 may be partially or entirely located in a circuit electrically connected to the charger 12. The control circuit 13 can determine whether a battery is placed in the charging compartment 11 and the state of the battery placed in the charging compartment 11 based on the battery parameters. The control circuit 13 can also determine the battery 30 to be charged based on the battery parameters. For example, when the SOC of the battery in the charging compartment 11 is less than a first preset value, the battery can be identified as the battery 30 to be charged. The first preset value ranges from 0 to 1 and can be set as needed; for example, the first preset value can be 97%, 99%, etc.

[0030] The battery status acquisition module 19 can also be used to detect faults in the battery inside the charging compartment 11. The battery parameters also include fault information. When a battery experiences a fault such as a short circuit or overcurrent, the control circuit 13 is also configured to identify the faulty battery based on the fault information, cut off the power supply from the charging module 16 to the charger 12 of the charging compartment 11 corresponding to the faulty battery, and further provide an alarm to ensure the safety of the charging process.

[0031] After the charging gun of the DC charging pile 20 is plugged into the power interface 15, under predetermined charging start conditions, the control circuit 13 sends a handshake message to the DC charging pile 20 through the power interface 15 to establish communication with the DC charging pile 20 according to the digital communication protocol standard between the DC charging pile 20 and the electric vehicle. In this embodiment, the charging system 10 also includes a battery simulation module 14 for simulating the electric vehicle battery voltage. The battery simulation module 14 is electrically connected to the control circuit 13 and the power interface 15, respectively. In some embodiments, when predetermined power acquisition conditions are met, the control circuit 13 controls the battery simulation module 14 to output simulated battery data to the DC charging pile 20 through the power interface 15, so as to pass the detection of the DC charging pile 20 and enter the charging preparation stage. The power acquisition conditions may include battery parameters detected by the battery simulation module 14 indicating that at least one charging compartment 11 contains a battery 30 to be charged. That is, when there is no battery 30 to be charged in the charging system 10, the charging system 10 will not send data to the DC charging pile 20 to enable the DC charging pile 20 to output electrical energy. The simulated battery data includes simulated battery state of charge (SOC) and simulated battery voltage. The simulated battery voltage is determined according to the relevant standards for electric vehicle battery voltage or according to the output voltage range in the obtained charging pile output capacity information. For example, the simulated battery voltage may be 3.2V. The simulated battery SOC can be determined based on the SOC of the batteries in at least one charging compartment 11. For example, in one embodiment, the simulated battery SOC can be determined as the minimum SOC of all the batteries 30 to be charged in the charging compartment 11 of the charging system 10. Thus, when the simulated battery SOC reaches a preset SOC to stop charging, it indicates that all the batteries 30 to be charged in the charging compartment 11 of the charging system 10 have been fully charged.

[0032] During the charging parameter configuration stage after the charging system 10 and the DC charging pile 20 handshake, the control circuit 13 also obtains the charging pile output capability information from the DC charging pile 20. The charging pile output capability information includes the maximum output current at the pile end, the output voltage range, etc.

[0033] After entering the charging state, the control circuit 13 determines the first power demand information according to preset rules. The first power demand information includes the reported demand current. The first power demand information is used to send a message to the DC charging pile 20 to simulate the process of sending a message to the DC charging pile 20 to set the battery charging demand when an electric vehicle is charging. This allows the DC charger to adjust the charging voltage, current, and other parameters according to the first power demand information to ensure that the charging process proceeds normally. The first power demand information needs to meet the corresponding range requirements in the charging pile output capacity information to ensure that the DC charger supplies power to the charging system 10.

[0034] In this embodiment of the invention, the first power demand information is determined at least based on the battery parameters of the battery 30 to be charged as determined in the charging system 10. For example, the total charging current required to charge these batteries 30 can be determined based on the number of batteries 30 to be charged and the charging current in the charging system 10, and the reporting demand current is determined based on the total charging current.

[0035] In this embodiment, the charging system 10 further includes auxiliary equipment 17, which may include thermal management equipment, human-machine interface equipment, communication equipment, etc. The thermal management equipment is used to perform thermal management on the charging system 10 and the battery being charged within it. For example, it may include temperature sensing components, heating components, cooling components, etc. Based on the temperature collected by the temperature sensing components, the thermal management equipment activates the heating components to increase the temperature or activates the cooling components to dissipate heat according to predetermined thermal management rules, thereby meeting the needs of charging safety and charging efficiency. The human-machine interface may include a human-machine interface that can display information such as the connection status of the charging system 10 and the DC charging pile 20, the battery status information of the battery 30 to be charged, the charging status of the battery 30 to be charged, and the location information of the battery 30 to be charged. Users can also control the charging system 10 through the human-machine interface. The communication device may include a wireless communication module and / or a wired communication module. The charging system 10 can communicate with external devices (such as cloud servers) through the communication device so that the external device can obtain the working status of the charging system 10, or the external device can send control commands to the charging system 10 to control the working status of the charging system 10.

[0036] The control circuit 13 is also configured to determine the power demand of the auxiliary device 17, which can be calculated based on the actual or expected power consumption of the auxiliary device 17 in the current operating mode. The first power demand information is also determined based on the power demand of the auxiliary device 17. In one embodiment, the control circuit 13 can determine one or more batteries 30 currently scheduled to require charging based on the battery parameters of all batteries 30 in the charging system 10, calculate the total charging current required to charge these batteries 30, and determine the total required current for the charging system 10 to operate based on the total charging current and the power demand of the auxiliary device 17. Since the DC charging pile 20 has a maximum output current limitation, the control circuit 13 can compare the total required current with the maximum output current at the charging pile 20 to determine the reported required current in the first power demand information ultimately sent to the DC charging pile 20. For example, when the total demand current is less than or equal to the maximum output current at the charging pile, the reported demand current can be determined as the calculated total demand current value; while when the total demand current is greater than the maximum output current at the charging pile, the reported demand current can be determined as the maximum output current at the charging pile, to ensure that the DC charging pile 20 can normally output electrical energy to the charging system 10. Furthermore, when the total demand current calculated by the control circuit 13 is greater than the maximum output current at the charging pile, the control circuit 13 can reduce the number of batteries 30 currently scheduled for charging, or reduce the charging current of the batteries 30.

[0037] During the charging process of the charging system 10 charging the batteries 30 in the charging compartment 11, the battery status acquisition module 19 can dynamically acquire the battery parameters of the batteries in the charging compartment 11. The control circuit 13 can also determine the charging status of each battery 30 based on the battery parameters acquired by the battery status acquisition module 19. When the batteries in the charging compartment 11 are fully charged, the control circuit 13 controls the charging module 16 to cut off the power supply to the charger 12 in the charging compartment 11 corresponding to that battery, thereby stopping the charging. Preferably, the control circuit 13 can also dynamically adjust the first power demand information based on the changes in the battery parameters of the batteries 30 during the charging process, so that the DC charging pile 20 adjusts its output according to the first power demand information to meet the working needs of the charging system 10. For example, when the battery parameters acquired by the battery status acquisition module 19 indicate that the number of batteries 30 that need to be charged has decreased, the control circuit 13 can correspondingly reduce the reported demand current value in the first power demand information sent to the DC charging pile 20.

[0038] When multiple batteries 30 are placed in the charging system 10, the maximum output capacity of the DC charging pile 20 may not be sufficient to charge all batteries 30 simultaneously. In this case, it is necessary to determine which of the multiple batteries 30 should be charged first. Furthermore, the multiple batteries 30 placed in the charging system 10 may have different performance parameters, states of charge, etc. In some scenarios, based on user needs, it may be desirable to prioritize charging specific batteries 30. Therefore, in some embodiments, when multiple batteries 30 are present, the control circuit 13 can determine the charging priority of the multiple batteries 30 according to a predetermined rule. During the charging process of the batteries 30 in the charging compartment 11, the charging priority order of the batteries 30 is used as the power allocation priority level of the charger 12 of the charging compartment 11 corresponding to the battery 30 by the charging module 16 during the charging process. The rule for determining the charging priority of multiple batteries 30 can be comprehensively determined based on actual needs, taking into account multiple influencing factors. For example, in one embodiment, batteries with poor performance or low remaining power can be given a higher charging priority to prevent over-discharge; in another embodiment, batteries with higher remaining power can be given a higher charging priority so that the charging system 10 can provide a fully charged battery as quickly as possible. During the charging process, the control circuit 13 can also dynamically adjust the charging priority of each battery 30 to be charged according to the battery parameters collected by the battery status acquisition module 19, thereby realizing dynamic adjustment of the charging power of each battery during the charging process.

[0039] When the last battery 30 to be charged is fully charged (that is, when there are no batteries 30 to be charged in the charging system 10), the control circuit 13 sends a stop charging message to the DC charging pile 20 to stop the power supply process.

[0040] In some embodiments, refer to Figure 3The charging module 16 includes an energy storage battery 18, which is electrically connected to the power interface 15. When the charging system 10 is connected to the DC charging pile 20 and a power supply relationship is established between the DC charging pile 20 and the charging system 10, the energy storage battery 18 can be charged using the electrical energy supplied by the DC charging pile 20. When the charging system 10 is not connected to the DC charging pile 20 or the output capacity of the DC charging pile 20 is insufficient, the energy storage battery 18 can serve as a backup or supplementary power source for the charging system 10, supplying power to each module in the charging system 10. During the charging process of the battery 30 to be charged, the control circuit 13 can, according to the connection status between the charging system 10 and the DC charging pile 20 and the output capacity of the DC charging pile 20, control the charging module 16 to supply power to the charger 12 of at least one charging compartment 11 corresponding to the battery 30 through the electrical energy provided by the DC charging pile 20, or connect the power path between the energy storage battery 18 and the charger 12 in the charging compartment 11 corresponding to at least one battery 30 to supply power to the charger 12.

[0041] Another embodiment of the present invention relates to a charging control method. Figure 4 This is a schematic flowchart of a charging control method according to an embodiment of the present invention, which can be applied to the charging system 10 described in at least some of the embodiments above, and is executed by the control circuit 13. Figure 4 As shown, the charging control method includes the following steps S110 to S150:

[0042] Step S110: Obtain the battery parameters of the battery in the charging compartment through the battery status acquisition module.

[0043] The battery acquisition module described in the above embodiment acquires the battery parameters of the battery in the charging compartment 11. The battery parameters may include, for example, the battery's in-situ state, the battery's state of charge (SOC), the charging current, the charging voltage, and other data.

[0044] Step S120: Determine the battery to be charged based on the battery parameters.

[0045] Based on the battery parameters, it can be determined whether a battery is placed in the charging system 10, and the state and performance parameters of the battery in the charging system 10. Based on the state of charge of the battery, it can be determined whether the battery in each charging compartment 11 is a battery 30 that needs to be charged, and the state of charge of the battery 30 is less than a first preset value.

[0046] Step S130: When the power supply conditions are met, control the battery simulation module to output simulated battery data to the DC charging pile.

[0047] The battery simulation module 14 is used to simulate the power battery of an electric vehicle for detection by the DC charging pile 20. Simulated battery data includes simulated battery state of charge (SOC) and simulated battery voltage. The simulated SOC is determined based on the SOC of the batteries in at least one charging compartment 11, for example, it can be determined based on the minimum SOC among the plurality of batteries to be charged 30. Power acquisition conditions include battery parameters indicating the presence of a battery to be charged 30 in at least one charging compartment 11; that is, the charging process for obtaining electrical energy from the DC charging pile 20 is initiated only when a battery to be charged 30 is present in the charging system 10, causing the battery simulation module 14 to output simulated battery data to the DC charging pile 20.

[0048] In one embodiment, before the battery simulation module 14 outputs simulated battery data to the DC charging pile 20, the control circuit 13 also obtains charging pile output capability information from the DC charging pile 20, including the maximum output current at the charging pile end. The control circuit 13 controls the battery simulation module 14 to output simulated battery data to the DC charging pile 20 based on the charging pile output capability information, so that the simulated battery data meets the corresponding requirements of the DC charging pile 20.

[0049] Step S140: Determine the first power demand information and send the first power demand information to the DC charging pile.

[0050] The first power demand information is determined at least based on the battery parameters of the battery 30 to be charged. The first power demand information may include the reported required current and required voltage. The control circuit 13 sends the first power demand information to the DC charging pile 20, so that the DC charging pile 20 supplies power to the charging system 10 according to the first power demand information. During the charging process, the control circuit 13 dynamically adjusts the first power demand information according to changes in battery parameters, so that the DC charging pile 20 can dynamically adjust its output.

[0051] Step S150: Control the charging module to supply power to the charger of at least one charging compartment corresponding to the battery to be charged.

[0052] After step S150, the following steps may also be included: when the state of charge of all batteries 30 to be charged reaches a predetermined value, a stop charging message is sent to the DC charging pile 20 to end the power supply of the DC charging pile 20 to the charging system 10.

[0053] In one embodiment, refer to Figure 5 The step of determining the reported demand current in the first power demand information in step S140 may include the following steps S141 to S144:

[0054] Step S141: Determine the total required current based on the battery parameters of the battery to be charged in the charging system and the power demand of the auxiliary equipment.

[0055] The charging system 10 also includes auxiliary equipment 17, which may include, for example, thermal management equipment, human-machine interface equipment, communication equipment, etc. The control circuit 13 is also configured to calculate the power demand of the auxiliary equipment 17 in the current operating state and determine the total required current based on the battery parameters of the battery 30 to be charged in the charging system 10 and the power demand of the auxiliary equipment 17.

[0056] Step S142: Compare the total required current with the maximum output current at the pile end.

[0057] Step S143: When the total demand current is less than or equal to the maximum output current at the pile end, the reported demand current is determined as the total demand current.

[0058] Step S144: When the total demand current is greater than the maximum output current at the pile end, the reported demand current is determined as the maximum output current at the pile end.

[0059] In one embodiment, when there are multiple batteries 30 to be charged in the charging system 10, the multiple batteries 30 can be prioritized for charging, and then power can be allocated to the multiple batteries 30 according to the charging priority order. (Refer to...) Figure 6 Step S150 may include the following steps S151 to S152:

[0060] Step S151: Determine the charging priority of multiple batteries to be charged.

[0061] During the charging process of the batteries 30 in the charging compartment 11, the charging priority order of the batteries 30 is used as the power allocation priority level of the charger 12 of the charging module 16 to the charging compartment 11 corresponding to the batteries 30. The rules for determining the charging priority of multiple batteries 30 can be determined comprehensively by considering multiple influencing factors according to actual needs. For example, in one embodiment, batteries with poor performance or low remaining power can be given a higher charging priority to avoid over-discharge; in another embodiment, batteries with higher remaining power can be given a higher charging priority so that the charging system 10 can provide a fully charged battery at the fastest speed.

[0062] Step S152: Control the charging module to supply power to the charger of the charging compartment corresponding to the battery according to the charging priority order of the batteries to be charged.

[0063] During the charging process, the control circuit 13 can also dynamically adjust the charging priority of each battery 30 to be charged according to the battery parameters collected by the battery status acquisition module 19, so as to realize the dynamic adjustment of the charging power of each battery during the charging process.

[0064] The technical solution of this embodiment of the invention utilizes a charging system 10 that can be mounted on a movable vehicle 40. The charging system 10 has a power interface 15 corresponding to the charging gun of the electric vehicle DC charging pile 20, and a battery simulation module 14 that simulates the voltage of a car battery. Therefore, the charging system 10 can use the existing electric vehicle DC charging pile 20 to charge the battery in the charging compartment 11, which improves the convenience of charging electric bicycle batteries and increases the utilization rate of the DC charging pile 20. Furthermore, the technical solution of this embodiment of the invention uses a battery status acquisition module 19 to collect battery parameters of the battery in the charging compartment 11. The control circuit 13 can automatically initiate corresponding data transmission with the DC charging pile 20 based on the battery parameters, enabling the DC charging pile 20 to power the charging system 10 or adjust the power supply parameters to the charging system 10, thereby achieving automated adjustment of the battery charging process.
