[0036] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0037] Figure 1 This is a schematic diagram of the structure of a charging control device provided by an embodiment of the present invention. The charging control device can be applied to an orderly charging system. The charging control device is compatible with existing charging piles and can control charging piles of different types and manufacturers to achieve orderly charging without changing the various functions of the existing charging piles. Figure 1 , the charging control device includes: an energy adapter 110 and an energy controller 120, the energy adapter 110 is communicatively connected with the energy controller 120;

[0038] The energy adapter 110 is connected between the charging controller 131 and the charging gun 132 of the charging pile 130 in the orderly charging system. The energy adapter 110 is used to respond to the energy controller 120 to adjust the operating parameters of the charging pile 130 and output the adjusted operating parameters to the energy controller 120;

[0039] The energy controller 120 is connected to the control platform 150 of the orderly charging system. The energy controller 120 is used to output the adjusted operating parameters to the control platform 150 of the orderly charging system. The operating parameters are used as a basis for the control platform 150 to formulate a charging strategy.

[0040] Specifically, the energy adapter 110 can obtain the orderly charging strategy issued by the energy controller 120 by communicating with the energy controller 120, and then adjust the operating parameters of the charging pile 130 according to the orderly charging strategy. The operating parameters of the charging equipment may include, for example, the output power, output voltage, output current, etc. of the charging pile 130. The energy adapter 110 adjusts the power limit of the connected charging controller 131 to adjust the output capacity of the charging controller 131 to achieve orderly charging in response to the energy controller 120.

[0041] The energy controller 120, by connecting to the control platform 150 of the ordered charging system, can obtain the charging policy issued by the control platform 150 and issue it as the ordered charging policy to the energy adapter 110, causing the energy adapter 110 to execute the ordered charging policy. Furthermore, the energy controller 120 transmits the received operating parameters of the charging pile 130 to the control platform 150, which serves as a basis for the control platform 150 to formulate the charging policy. The charging policy in this embodiment is specifically an ordered charging policy. It should be noted that both the energy controller 120 and the control platform 150 in this embodiment can formulate ordered charging policies. To distinguish the ordered charging policies formulated by the energy controller 120 and the control platform 150, this embodiment of the present invention designates the charging policy formulated by the control platform 150 as the first ordered charging policy and the charging policy formulated by the energy controller 120 as the second ordered charging policy. In this embodiment of the present invention, the terms "first" and "second" are used to describe the corresponding charging policies to distinguish the charging policies formulated by the two control units, and should not be construed as limiting the charging policies.

[0042] Optional, Figure 2 The communication topology diagram of the charging control device provided by the embodiment of the present invention is shown in FIG. Figure 2In this embodiment, the energy controller 120 can communicate with multiple energy adapters 110, and bidirectional communication is achieved between the energy controller 120 and the energy adapters 110, as well as between the energy controller 120 and the control platform 150. On the one hand, the energy controller 120 issues an orderly charging strategy to the energy adapters 110, and on the other hand, the energy adapters 110 provide feedback to the energy controller 120 on the current operating parameters and charging status of the charging piles 130. The energy controller 120 further feeds back the received information on the current operating parameters and charging status of each charging pile 130 to the control platform 150 of the orderly charging system, allowing the control platform 150 to adjust the first orderly charging strategy in real time based on the current operating status of each charging pile 130 to ensure the stability of the power grid.

[0043] For example, if the current power consumption is at peak, the control platform 150 of the orderly charging system determines that the output power to the vehicle needs to be reduced to maintain grid stability based on the current load conditions and the output capacity of the power supply device 120. At this time, the energy adapter 110 responds to the first orderly charging strategy formulated by the control platform 150 and transmitted by the energy controller 120, and reduces the power limit of the charging station 130. The charging station 130 uses this power limit as the current maximum allowable output power and notifies the vehicle's battery management system, thereby achieving orderly charging during the charging process, outputting a charging power that does not exceed this power limit. Alternatively, if the power supply device 120 currently has no power headroom and the orderly charging strategy at this time indicates that power output to the vehicle needs to be suspended, the energy controller 120 sets the power limit to zero. In this state, although the vehicle is connected to the charging system, the charging system will not charge the vehicle to implement the orderly charging strategy.

[0044] In this embodiment of the present invention, an energy controller 120 and an energy adapter 110 are provided. The energy controller 120 is connected to the control platform 150 of the orderly charging system to receive a charging strategy formulated by the control platform 150 and transmit the charging strategy to the energy adapter 110 as the current orderly charging strategy. The energy adapter 110 adjusts the power limit of the charging pile 130 according to the received orderly charging strategy, thereby adjusting the maximum allowable output power of the charging pile 130 and controlling the charging pile 130 to execute the orderly charging strategy. The charging control device provided in this embodiment can achieve orderly charging by changing the output power of the charging pile 130 without changing the original structure and existing charging control logic of each charging pile 130. Therefore, the charging control device provided in this embodiment of the present invention is applicable to the case where charging piles 130 of different types or manufacturers are connected to the orderly charging system to execute the orderly charging strategy, eliminating the human and financial costs of modifying the charging pile 130 and controlling the charging pile 130 to execute the orderly charging strategy in a cost-effective manner.

[0045] Optionally, based on the above embodiment, continue to refer to Figure 1 The energy controller 120 is also connected to the power supply device 120 of the orderly charging system. The energy controller 120 is also used to obtain the power capacity and load power of the power supply device 120, and output the power capacity and load power to the control platform 150, wherein the power capacity is used to determine the power upper limit of the orderly charging system; the load power is used to determine the power margin of the orderly charging system.

[0046] Specifically, the power supply device 120 of the orderly charging system may be, for example, a transformer 160. When the power supply device 120 of the orderly charging system is a transformer 160, as shown in FIG. Figure 2 As shown, energy controller 120 is connected to power distribution terminal 170 of transformer 160 to collect the power capacity and load power of transformer 160 through distribution terminal 170. Energy controller 120 collects the power capacity of power supply device 120 to set the upper power limit of the orderly charging system. Energy controller 120 also collects the load power of power supply device 120 and calculates the current power margin based on this load power.

[0047] Energy controller 120 outputs the power capacity and power headroom to control platform 150, which then uses it to manage the power of the ordered charging system and formulate a first ordered charging strategy. For example, when a user sends a charging command to control platform 150 via a terminal device, control platform 150 formulates a first ordered charging strategy that matches the current operating conditions of the power grid based on the power headroom feedback from energy controller 120 and the set power cap. This strategy is then transmitted to energy controller 120, which then transmits it to energy adapter 110 to execute ordered charging.

[0048] In an optional embodiment, the power supply device 120 is specifically a transformer 160, and single-phase electricity (220V±15%, 50±1Hz) is drawn from the low-voltage side of the transformer 160, and two routes are separated to supply power to the energy controller 120 and the charging pile 130 respectively. The air switch QF1 (normally closed) is used as a circuit protection switch on the charging pile 130 side, and the air switch QF2 (normally closed) is used as a circuit protection switch on the energy controller 120 side.

[0049] Optionally, based on the above embodiment, when the control platform 150 does not issue the first orderly charging strategy, the energy controller 120 is further configured to formulate a second orderly charging strategy according to the power margin of the power supply device 120 in the orderly charging system.

[0050] From the above analysis, it can be seen that the energy controller 120 can not only dispatch the charging strategy formulated by the scheduling control platform 150 as an orderly charging strategy, but also formulate an orderly charging strategy on its own when the control platform 150 does not output the charging strategy. Under this working condition, the energy controller 120 formulates a second ordered charging strategy based on the current power margin collected as an ordered charging strategy. At this time, the energy adapter 110 responds to the second ordered charging strategy and sends a power limit to the charging pile 130 to adjust the maximum allowable output power of the charging pile 130.

[0051] Optionally, based on the above embodiment, when the charging pile 130 is connected to the device to be charged and the control platform 150 receives a charging command from the terminal device, the energy controller 120 dispatches the first orderly charging strategy formulated by the control platform 150 for output;

[0052] When the charging pile 130 is connected to the device to be charged and the control platform 150 has not received a charging command from the terminal device, the energy controller 120 formulates a second orderly charging strategy for output.

[0053] Specifically, the control platform 150 can communicate with the user's terminal device to receive the user's charging commands. The user can select the desired charging method through the application software configured in the terminal device. The control platform 150 then issues the corresponding charging strategy according to the preset priority based on the user's selection. The energy controller 120 then transmits the charging strategy of the control platform 150 to the energy adapter 110, which controls the charging station 130 to execute the orderly charging strategy.

[0054] When the user connects the vehicle to the orderly charging system but does not send a charging command to the control platform 150, the control platform 150 will not issue a charging strategy at this time. At this time, the energy controller 120 formulates a second orderly charging strategy based on the collected load power and the determined power margin as the ordered charging strategy and sends it to the energy adapter 110. The energy adapter 110 controls the charging pile 130 to perform orderly charging according to the second ordered charging strategy.

[0055] Optional, Figure 3 This is a structural diagram of another charging control device provided by an embodiment of the present invention. Figure 3 , the energy adapter 110 includes an adapter communication module 111, an orderly charging execution module 112 and a voltage and current sampling module 113;

[0056] The adapter communication module 111 is used to communicate with the energy controller 120 to achieve interaction between the energy adapter 110 and the energy controller 120;

[0057] One end of the ordered charging execution module 112 is connected to the charging controller 131, and the other end is connected to the charging gun 132. The ordered charging execution module 112 is used to send a current output limit value to the charging controller 131, wherein the current output limit value is used as the maximum allowable output current of the charging pile;

[0058] The voltage and current sampling module 113 is connected to the current output circuit of the charging pile 130 . The voltage and current sampling module 113 is used to collect the output current and output voltage of the current output circuit as adjusted operating parameters.

[0059] Specifically, the adapter communicates with the energy controller 120 through the built-in communication module, exchanges data, obtains the orderly charging strategy issued by the energy controller 120, and sends the collected operating parameters of the charging pile 130 to the energy controller 120.

[0060] The CP port and PE port of the orderly charging execution module 112 are respectively connected to the CP output and PE output of the charging controller 131 and the CP interface and PE interface of the charging gun 132. The CP output is used to transmit a PWM square wave signal, and the PE output is grounded and used as a safety line. The orderly charging execution module 112 adjusts the current output limit by changing the duty cycle of the PWM square wave signal. The charging pile 130 uses the adjusted current output limit as the current maximum allowable output current to communicate with the battery management system of the device to be charged. The charging pile 130 outputs a charging current that does not exceed the current output limit to charge the device to be charged, thereby implementing an orderly charging strategy. In one embodiment, the charging pile 130 is an AC charging pile, and the energy adapter 110 is connected to the AC charging controller of the AC charging pile. The CP output of the AC charging controller is used as the input of the energy adapter 110. The energy adapter 110 plays the role of changing the PWM duty cycle, thereby changing the output current limit of the AC charging pile. The energy adapter 110 only responds to the orderly charging strategy to change the PWM square wave of the original charging pile 130, without affecting any control logic of the original charging pile 130, such as the control of the contactor, the human-computer interaction method, the working mode of the emergency stop switch, etc. Therefore, the energy adapter 110 does not need to understand the control method of the original charging pile 130, so that the existing orderly charging pile can be modified in the most economical way, and the orderly charging system can be connected through the energy controller 120 to achieve orderly charging.

[0061] The voltage and current sampling module 113 collects the output current and output voltage of the current output circuit of the charging pile 130, and sends the output current and output voltage as adjusted operating parameters to the energy controller 120, so that the control platform 150 can determine whether the charging pile 130 is currently implementing an orderly charging strategy based on the operating parameters of the charging pile 130 fed back by the energy controller 120.

[0062] Optionally, based on the above embodiment, continue to refer to Figure 3 , the energy controller 120 includes a controller communication module 121, a collection module 122 and an orderly charging module 123;

[0063] The controller communication module 121 includes a first communication submodule, a second communication submodule, and a third communication submodule. The first communication submodule is used to communicate with the energy adapter 110, the second communication submodule is used to communicate with the control platform 150, and the third communication submodule is used to communicate with the power supply device 120 of the orderly charging system.

[0064] The acquisition module 122 is used to obtain the power capacity and load power of the power supply device 120 through the third communication submodule;

[0065] The ordered charging module 123 is used to schedule the first ordered charging strategy output by the control platform 150 or formulate a second ordered charging strategy.

[0066] Specifically, the energy controller 120 sends an orderly charging strategy to the energy adapter 110 through the first communication submodule, and receives the output signal of the energy adapter 110 through the first communication submodule. The output signal may include, for example, all status information of the charging process, such as the status of the charging pile 130 and the operating parameters of the charging pile 130. The energy controller 120 interacts with the control platform 150 through the second communication submodule to receive the first orderly charging strategy sent by the control platform 150, and feeds back the output signal of the energy mismatch device to the control platform 150 through the second communication submodule. The energy controller 120 interacts with the power supply device 120 through the third communication submodule to collect the power capacity and load power of the power supply device 120 in order to formulate an orderly charging strategy.

[0067] Optionally, the first communication submodule is one of an HPLC communication module, an RS485 communication module, an RS232 communication module, a CAN communication module, and an Ethernet communication module. In a preferred embodiment of the present invention, the first communication submodule adopts an HPLC communication module.

[0068] Optionally, the second communication submodule is a mobile communication module, and the mobile communication module may be, for example, a 4G communication module or a 5G communication module.

[0069] Optionally, the third communication submodule is an RS485 communication module or an Ethernet communication module.

[0070] The collection module 122 collects load information of the power supply device 120 and stores it locally.

[0071] In this embodiment of the present invention, an energy adapter 110 is connected to a charging controller 131 of a charging pile 130, and an energy controller 120 is connected to a control platform 150 of an orderly charging system. Furthermore, communication is performed between the energy controller 120 and the energy adapter 110, so that the energy adapter 110 can adjust the current output limit by modifying the duty cycle of the PWM signal of the charging controller 131 in the charging pile 130 according to an effective charging strategy formulated or scheduled by the energy controller 120, so that the charging pile 130 charges the load with a charging current that does not exceed the current output limit, thereby controlling the charging pile 130 to execute the orderly charging strategy. The energy controller 120 collects the load power and power capacity of the power supply device 120, and sends the current power margin and the operating parameters of the charging pile 130 fed back by the energy adapter 110 to the control platform 150. The control platform 150 then formulates a first orderly charging strategy. Alternatively, if the control platform 150 does not issue the first orderly charging strategy, the energy controller 120 independently formulates a second orderly charging strategy and issues it to the energy mismatch device as the current orderly charging strategy. The embodiment of the present invention adds an energy adapter to the charging pile, which is connected to the charging pile main control board interface. Without changing the original functions of the charging pile, the charging pile's communication, current and voltage sampling, and orderly charging execution functions are added. At the same time, to enable a large number of AC charging piles to be connected to the orderly charging system, the embodiment of the present invention connects the improved charging pile to the energy controller, which can statically set the upper power limit, dynamically track the remaining power in the area, and receive the platform's orderly charging strategy and scheduling.
