Abstract
Description
Technical Field
[0001] The present invention relates to the field of charging technology, and in particular to a control method, device, equipment and medium for a charging module. Background Art
[0002] As a key device for providing electric vehicles with power, the core component of the charging pile is the charging module. When the traditional current limiting setting is large, the module output current rise rate is too fast, and the output voltage and current overshoot will occur. The performance indicators of the module cannot fully meet the relevant standards, and in severe cases, the output overvoltage protection will shut down. The output current rise rate is too fast, which is actually caused by the slow response speed of the current loop when the module starts. However, too fast a response speed will prolong the adjustment time and even cause loop oscillation, and the module cannot work properly.
[0003] At the same time, when the module output current overshoots, the module's instantaneous output power is too large, which will also cause the energy transmitted on the primary side to be too large, causing the primary and secondary power devices (such as switching tubes and rectifier tubes) to bear too much short-term current. If the device is not sufficiently derated during device selection, it may cause device damage or damage in serious cases. Excessive current transmitted on the primary side may also cause primary side overcurrent protection (OCP), causing the module to shut down and fail to start up normally. Summary of the invention

[0042] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.
[0043] Therefore, the following 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 for protection, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
[0044] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0045] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.
[0046] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.
[0047] Before explaining a control method for a charging module provided in an embodiment of the present application, a charging device to which the control method for a charging module is applied is first explained.
[0048] Figure 1 A schematic diagram of a charging device provided in an embodiment of the present application. Figure 1 As shown, the charging device includes: a control module 1 and a charging module 2, the control module 1 is connected to the charging module 2, and the control module 1 is used to execute the steps of a charging module control method provided in an embodiment of the present application.
[0049] For example, the charging device is a vehicle charging station for charging an electric vehicle.
[0050] During the charging operation of the charging module, when the charging module issues a power-on command, the module enters the soft start process, wherein the soft start process includes four stages: soft start initialization stage, soft start wave generation stage, output voltage establishment stage and normal operation stage.
[0051] The soft start initialization stage is to initialize the variables used in the soft start process to prevent soft start failures caused by uninitialized variables during the soft start process.
[0052] The soft start wave generation stage is to complete the initialization and determine that the module has no faults before the wave generation, assign the set voltage value to the given voltage value, and assign the set current value to the given current value.
[0053] During the output voltage establishment phase, the charging module output voltage will be increased from 0 to the set voltage value.
[0054] The normal operation stage is to wait for the output voltage to reach the set voltage value, and then the charging module completes the soft start and operates normally.
[0055] A control method for a charging module provided in an embodiment of the present application is explained below through a specific example. Figure 2 A flow chart of a control method of a charging module provided in an embodiment of the present application. Figure 2 As shown, the method includes:
[0056] S101. Generate and send a first control signal to a charging module according to a set voltage value and a set current value.
[0057] So that the charging module performs a voltage establishment process based on the set voltage value and the set current value.
[0058] The set voltage value is a voltage value determined in advance according to the characteristic attributes of the charging module, which is generally less than or equal to the maximum voltage value of the charging module. The set current value is a current value determined in advance according to the characteristic attributes of the charging module, which is generally less than or equal to the maximum current value of the charging module.
[0059] When the charging device is turned on, it will first charge at a set current value to improve the charging efficiency, so that the output voltage of the charging module reaches the set voltage value as soon as possible and the charging module reaches a normal operating state as soon as possible.
[0060] By way of example, the first control signal is a PWM (Pulse Width Modulation) signal.
[0061] S102: If the current output voltage of the charging module reaches a preset ratio of the set voltage value, a second control signal is regenerated and sent to the charging module according to the preset minimum output current value of the charging module and the set voltage value.
[0062] After the output voltage of the charging module reaches a given voltage value, the current establishment process is executed according to the preset minimum output current value, so that the output current reaches the maximum output current value corresponding to the set voltage value.
[0063] For example, the preset ratio is 80%. If the current output voltage of the charging module reaches 80% of the set voltage value, it indicates that the voltage establishment process is about to be completed. If charging continues with a larger current value, it may cause an overshoot of the output voltage and current. Therefore, the current establishment process is performed according to the preset minimum output current value of the charging module to avoid overshoot caused by high current charging.
[0064] For example, from 80% of the set voltage value to 100% of the set voltage value, the current establishment process can be performed based on the preset minimum output current value. The output current value can also be gradually increased based on the preset minimum output current value until the output current reaches the maximum output current value corresponding to the set voltage value. This improves the charging efficiency while avoiding overshoot.
[0065] In summary, in this embodiment, according to the set voltage value and the set current value, a first control signal is generated and sent to the charging module, so that the charging module performs a voltage establishment process based on the set voltage value and the set current value; if the current output voltage of the charging module reaches a preset ratio of the set voltage value, then according to the preset minimum output current value of the charging module and the set voltage value, a second control signal is regenerated and sent to the charging module, so that after the output voltage of the charging module reaches a given voltage value, the current establishment process is performed according to the preset minimum output current value, so that the output current reaches the maximum output current value corresponding to the set voltage value. Thus, the current output voltage of the charging module is compared with the set voltage value, and the output current is controlled, which avoids current overshoot, protects the safety of the equipment, and improves the charging efficiency.
[0066] In the above Figure 2On the basis of the corresponding embodiment, the embodiment of the present application further provides a method for generating a first control signal according to a set voltage value and a set current value. Figure 3 A flow chart of a method for generating a first control signal according to a set voltage value and a set current value provided in an embodiment of the present application. Figure 3 As shown, in S101, generating and sending a first control signal to the charging module according to the set voltage value and the set current value includes:
[0067] S201. According to the set voltage value and the set current value, respectively set a given voltage value and a given current value.
[0068] For example, the given voltage value may be set equal to the set voltage value, and the given current value may be set equal to the set current value. By setting the given voltage value and the given current value respectively according to the set voltage value and the set current value, the charging efficiency is improved after charging is initialized.
[0069] S202: Generate and send a first control signal to a charging module according to a given voltage value and a given current value.
[0070] The given voltage value and the given current value are transmitted to the charging module, so that the charging module uses the given voltage value as a voltage reference and charges with the given current value.
[0071] In summary, in this embodiment, the given voltage value and the given current value are set according to the set voltage value and the set current value, respectively; and the first control signal is generated and sent to the charging module according to the given voltage value and the given current value. Thus, after charging is initialized, the charging efficiency is improved.
[0072] In the above Figure 2 On the basis of the corresponding embodiment, the embodiment of the present application further provides a method for generating a first control signal according to a set voltage value and a set current value. Figure 4 A flow chart of a method for generating a second control signal according to a preset minimum output current value and a set voltage value provided in an embodiment of the present application. Figure 4 As shown, in S102, according to the preset minimum output current value and the set voltage value of the charging module, regenerating and sending the second control signal to the charging module includes:
[0073] S301. Update the given current value to a preset minimum output current value of the charging module.
[0074] S302: Regenerate and send a second control signal to the charging module according to the updated given current parameter value and the given voltage value.
[0075] The updated given current parameter value and the given voltage value are transmitted to the charging module, so that the charging module uses the given voltage value as a voltage reference and performs charging with the updated given current parameter value.
[0076] The updated given current parameter is a smaller current value, and the current establishment process is executed according to the smaller current value to avoid overcharge caused by large current charging.
[0077] In summary, in this embodiment, the given current value is updated to the preset minimum output current value of the charging module; according to the updated given current parameter value and the given voltage value, the second control signal is regenerated and sent to the charging module. Thus, the current establishment process is executed according to the updated given current parameter value to avoid overcharge caused by high current charging.
[0078] In the above Figure 2 On the basis of the corresponding embodiment, in another embodiment of the present application, in S102, according to the preset minimum output current value and the set voltage value of the charging module, regenerating and sending the second control signal to the charging module includes:
[0079] If the current output voltage of the charging module reaches a preset proportion of the set voltage value, and the load mode of the charging module is a battery load mode, a second control signal is regenerated and sent to the charging module according to the preset minimum output current value and the set voltage value of the charging module.
[0080] If the load mode of the charging module is the battery load mode, the battery is in the charging state, the charging module charges the battery, and the battery is at risk of overcharging. Therefore, if the current output voltage of the charging module reaches a preset ratio of the set voltage value, a second control signal is regenerated and sent to the charging module according to the preset minimum output current value and the set voltage value of the charging module. The preset minimum output current value and the set voltage value are transmitted to the charging module so that the charging module uses the set voltage value as a voltage reference and charges at the preset minimum output current value to avoid overcharging caused by high current charging.
[0081] In summary, in this embodiment, if the current output voltage of the charging module reaches a preset ratio of the set voltage value, and the load mode of the charging module is the battery load mode, then according to the preset minimum output current value and the set voltage value of the charging module, a second control signal is regenerated and sent to the charging module. Thus, charging is performed at the preset minimum output current value to avoid overcharge caused by high current charging.
[0082] On the basis of the above embodiments, the embodiments of the present application further provide a method for generating a first control signal according to a set voltage value and a set current value. Figure 5 A flow chart of a method for determining a loading mode of a charging module provided in an embodiment of the present application. Figure 5As shown, if the current output voltage of the charging module reaches a preset ratio of the set voltage value, and the load mode of the charging module is a battery load mode, then according to the preset minimum output current value and the set voltage value of the charging module, before regenerating and sending the second control signal to the charging module, the method also includes:
[0083] S401, determining whether the current output voltage of the charging module reaches a preset ratio of the set voltage value, and whether the current output current of the charging module is less than a preset current value.
[0084] The preset current value is greater than the preset minimum output current value. For example, the preset current value may be 2A.
[0085] S402: If the current output voltage of the charging module reaches a preset ratio of the set voltage value, and the current output current of the charging module is less than the preset current value, then the loading mode of the charging module is determined to be the battery loading mode.
[0086] If the current output voltage of the charging module reaches a preset ratio of the set voltage value and the current output current of the charging module is less than the preset current value, it indicates that the output voltage and output current of the charging module are not established synchronously, and the load mode of the charging module is determined to be the battery load mode.
[0087] S403: If the current output voltage of the charging module reaches a preset ratio of the set voltage value, and the current output current of the charging module is greater than or equal to the preset current value, then the load mode of the charging module is determined to be a resistance load mode.
[0088] If the current output voltage of the charging module reaches a preset ratio of the set voltage value, and the current output current of the charging module is greater than or equal to the preset current value, it indicates that the output voltage and output current of the charging module are established synchronously, and the load mode of the charging module is determined to be the resistance load mode.
[0089] By determining the load mode of the charging module in advance based on the output voltage and output current of the charging module, it is convenient to accurately control the charging module later.
[0090] In summary, in this embodiment, it is determined whether the current output voltage of the charging module reaches a preset ratio of the set voltage value, and whether the current output current of the charging module is less than the preset current value; the preset current value is greater than the preset minimum output current value; if the current output voltage of the charging module reaches a preset ratio of the set voltage value, and the current output current of the charging module is less than the preset current value, then the load mode of the charging module is determined to be a battery load mode; if the current output voltage of the charging module reaches a preset ratio of the set voltage value, and the current output current of the charging module is greater than or equal to the preset current value, then the load mode of the charging module is determined to be a resistance load mode. Thus, by determining the load mode of the charging module in advance according to the output voltage and output current of the charging module, it is convenient to accurately control the charging module later.
[0091] Furthermore, in another embodiment of the present application, if the load mode of the charging module is determined to be a resistance load mode, the output voltage and the output current can be basically established at the same time, and there is no overshoot, so the given current value is kept equal to the set current value. Thus, according to the different load modes of the charging module, different current starting strategies are adapted to avoid the situation where the output current is abnormal due to the use of the same strategy.
[0092] In the above Figure 2 On the basis of the corresponding embodiment, in another embodiment of the present application, in S102, according to the preset minimum output current value and the set voltage value of the charging module, regenerate and send a second control signal to the charging module, so that after the output voltage of the charging module reaches the given voltage value, the current establishment process is executed according to the preset minimum output current value, so that the output current reaches the maximum output current value corresponding to the set voltage value, including:
[0093] According to the preset minimum output current value, the first preset current adjustment step and the set voltage value, a second control signal is regenerated and sent to the charging module, so that after the output voltage of the charging module reaches the given voltage value, the current establishment process is executed according to the preset minimum output current value and the first preset current adjustment step, so that the output current of the charging module gradually reaches the maximum output current value corresponding to the given voltage value.
[0094] For example, the first preset current adjustment step may be 0.5 A / S.
[0095] After the second control signal is used to control the charging module to charge, if the preset minimum output current value is always used for charging, the charging time will be too long and the charging efficiency will be too low. Therefore, the preset minimum output current value is used for current output until the current output voltage of the charging module reaches the set voltage value. After the output voltage is fully established, the output current value of the charging module can be gradually increased by using the first preset current adjustment step on the basis of the preset minimum output current value until the output current of the charging module reaches the maximum output current value. Thus, the charging efficiency is improved while avoiding current overshoot.
[0096] In summary, in this embodiment, according to the preset minimum output current value, the first preset current adjustment step and the set voltage value, the second control signal is regenerated and sent to the charging module, so that after the output voltage of the charging module reaches the given voltage value, the current establishment process is performed according to the preset minimum output current value and the first preset current adjustment step, so that the output current of the charging module gradually reaches the maximum output current value corresponding to the given voltage value. Thus, the charging efficiency is improved while avoiding current overshoot.
[0097] In the above Figure 2 On the basis of the corresponding embodiment, in another embodiment of the present application, the method further includes:
[0098] If the current output voltage of the charging module reaches the set voltage value, and the current output current of the charging module reaches the maximum output current value corresponding to the given voltage value, a third control signal is generated and sent to the charging module according to the second preset current adjustment step, so that after the output current of the charging module reaches the maximum output current value corresponding to the given voltage value, the charging module gradually adjusts to the set current value based on the second preset current adjustment step.
[0099] For example, the second preset current adjustment step is 20 A / S.
[0100] When the current output voltage of the charging module reaches the set voltage value, and the current output current of the charging module reaches the maximum output current value corresponding to the given voltage value, it indicates that the voltage and current have been established and the charging module has entered the normal operating mode. The current regulation speed can be increased to improve the charging efficiency of the charging module.
[0101] It should be noted that when the current output voltage of the charging module reaches the set voltage value, and the current output current of the charging module reaches the maximum output current value corresponding to the given voltage value, if the output current needs to be further adjusted, a third control signal is generated and sent to the charging module according to the second preset current adjustment step.
[0102] When the current output voltage of the charging module reaches the set voltage value, and the current output current of the charging module reaches the maximum output current value corresponding to the given voltage value, if the output current does not need to be further adjusted, the current output current value is maintained without adjustment, and the third control signal is not generated according to the second preset current adjustment step.
[0103] In summary, in this embodiment, if the current output voltage of the charging module reaches the set voltage value, and the current output current of the charging module reaches the maximum output current value corresponding to the given voltage value, then according to the second preset current adjustment step, a third control signal is generated and sent to the charging module, so that after the output current of the charging module reaches the maximum output current value corresponding to the given voltage value, the charging module is gradually adjusted to the set current value based on the second preset current adjustment step. Thus, when the charging module enters the normal operating mode, the charging efficiency of the charging module is improved.
[0104] Furthermore, in another embodiment of the present application, a control method of a charging module provided in the present application is explained by taking an example.
[0105] First, the variables used in the soft start process are initialized in the soft start initialization stage of the soft start module. After the initialization is completed and the charging module is judged to be fault-free, the wave is generated, and the set voltage 300V value is assigned to the given voltage, and the set current 100A is assigned to the given current. When the output voltage of the charging module is greater than or equal to 80% of 300V, that is, 240V, and the output current is less than 2A, it indicates that the charging module is connected to the battery load. Set the electronic load setting voltage to 285V, 240V is less than 285V, and the charging module has no output current. Therefore, the given current value is updated to the minimum current value of 0.6A that the module can output. When the output voltage is fully established, the current soft start is performed: the current slow increase control is performed by comparing the current value of the charging module with the set current value, and the output current is gradually increased to the maximum current value.
[0106] When the output voltage of the charging module is greater than or equal to 80% of 300V, that is, 240V, and the output current is greater than or equal to 2A, it indicates that the charging module is connected to a resistance load. When the output voltage of the charging module is established, the output current is also established synchronously from zero to a certain value, so the output current is not processed.
[0107] By judging the normal operation time of the module, the module is considered to be in the current soft start stage in the first 5 seconds, and the step length is set according to the current limiting startup strategy; after 5 seconds, the module is considered to be in the current regulation stage, and the current regulation step length is 20A / S.
