Detailed Description
The core of the invention is to provide a parameter management method, a system and a device of a modular charger, which solve the problem of unmatched charging module parameters and further improve the charging performance and reliability of the modular charger.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a parameter management method of a modular charger according to an embodiment of the present invention.
The parameter management method of the modular charger is applied to the modular charger comprising a plurality of parallel charging modules, and comprises the following steps:
step S1: and acquiring the current charging parameters of the target charging module.
The target charging module in step S1 is any one of the plurality of charging modules of the modular charger.
Specifically, it is known that when charging parameters of a plurality of charging modules in a modular charger are configured, the charging parameters of the plurality of charging modules should be kept consistent, otherwise, the plurality of charging modules may not be equalized, and the charging performance of the modular charger may be reduced. Based on this, in consideration that the charging parameters of some charging modules may be changed due to some factors, so that the charging parameters of the charging modules are not matched with those of the rest charging modules, and if some charging modules have maintenance and replacement conditions (it should be noted that the processes of maintenance, replacement and re-electrification of the charging modules do not affect the operation of the rest charging modules), the charging parameters of the replaced new charging modules may be different from those of the old charging modules, so that the charging performance and reliability of the modular charger are reduced.
Step S2: judging whether the current charging parameter is within a preset parameter range; if not, step S3 is executed.
It should be noted that the preset of the present application is set in advance, and only needs to be set once, and the reset is not needed unless the modification is needed according to the actual situation.
Specifically, this application sets up the parameter range for the charging parameter of the module of charging in advance, and its setting principle does: when the charging parameters of the charging module are within the set parameter range, the charging parameters of the charging module are not changed, and the condition of parameter mismatching cannot be caused; when the charging parameters of the charging module are not in the set parameter range, the charging parameters of the charging module are considered to be changed, and the situation of parameter mismatching can be caused.
Based on the above, after the current charging parameter of the target charging module is obtained, whether the current charging parameter of the target charging module is within a preset parameter range is judged; if the current charging state is within the preset parameter range, the charging parameter of the target charging module does not need to be corrected, and the controller in the target charging module can control the target charging module to keep the current charging state to operate; if the target charging parameter is not within the preset parameter range, the charging parameter of the target charging module needs to be corrected, and then the controller in the target charging module controls the target charging module to operate based on the corrected charging parameter.
Step S3: and sending the preset standard charging parameters to the target charging module so that the target charging module performs parameter configuration again according to the standard charging parameters.
Specifically, when the current charging parameter of the target charging module is not within the preset parameter range, the charging parameter of the target charging module needs to be corrected, that is, the preset standard charging parameter is sent to the target charging module, so that the controller inside the target charging module reconfigures the parameters of the target charging module according to the standard charging parameter, and the charging parameters of the plurality of charging modules are ensured to be consistent.
It should be noted that more than one charging parameter of the target charging module is provided, each charging parameter corresponds to a parameter range and a standard charging parameter that can determine whether the charging parameter is reasonable, and when any charging parameter is not within the corresponding parameter range, the standard charging parameter corresponding to the charging parameter is sent to the target charging module, so that the target charging module assigns the charging parameter again according to the standard charging parameter corresponding to the charging parameter.
The invention provides a parameter management method of a modular charger, which is used for acquiring the current charging parameter of any charging module in the modular charger, judging whether the current charging parameter is in a preset parameter range, if not, indicating that the parameters of the charging module are not matched, sending the preset standard charging parameter to the charging module so that the charging module performs parameter configuration again according to the standard charging parameter, thereby solving the problem of parameter mismatching of the charging module and further improving the charging performance and reliability of the modular charger.
On the basis of the above-described embodiment:
as an alternative embodiment, the process of obtaining the current charging parameter of the target charging module includes:
periodically sending a reading instruction to a target charging module;
and receiving the current charging parameters returned by the target charging module after receiving the reading instruction.
Specifically, the charging parameters of the target charging module are stored in a memory inside the target charging module, and then the method for acquiring the current charging parameters of the target charging module in the present application is as follows: periodically sending a reading instruction to a target charging module; and after receiving the reading instruction, the controller in the target charging module acquires the current charging parameter of the target charging module from the memory of the controller, and returns the current charging parameter to the target charging module.
As an optional embodiment, the parameter management method further includes:
starting timing when a reading instruction is sent, and judging whether the target charging module returns the current charging parameters or not when the timing time reaches a preset time threshold;
if so, determining that the communication of the target charging module is normal;
if not, determining that the communication of the target charging module is abnormal.
Furthermore, timing can be started when a reading instruction is sent to the target charging module, and when the timing time reaches a preset time threshold value, if the current charging parameters returned by the target charging module are received, the communication of the target charging module is determined to be normal; if the current charging parameters returned by the target charging module are not received, determining that the communication of the target charging module is abnormal, and finishing obtaining the charging parameters of the target charging module.
As an optional embodiment, the parameter management method further includes:
when the communication of the target charging module is abnormal, the target charging module is controlled to keep the existing charging state to operate by using a controller in the target charging module.
Further, when the communication of the target charging module is abnormal, the current charging parameters of the target charging module cannot be acquired and the subsequent steps are executed, but the target charging module still needs to be kept in online operation, so that the whole charging system can work normally.
Specifically, the control principle that the target charging module keeps running online when the communication is abnormal is as follows: some information needs to be shared among the plurality of charging modules, that is, information interaction is needed among the plurality of charging modules, as shown in fig. 2, the plurality of charging modules realize information interaction through communication (not limited to CAN/SCI/LIN/WIFI communication). Based on the above, the controller in the target charging module detects whether the communication of the target charging module is abnormal, specifically detects whether the target charging module can receive the shared information of other charging modules (there are two conditions, namely that only the target charging module in the modular charger operates online; if not, determining that the communication of the target charging module is abnormal, and controlling the target charging module to keep the existing charging state to operate.
As an optional embodiment, the parameter management method further includes:
numbering a plurality of charging modules in advance;
and when the current charging parameter is not in the preset parameter range, recording the number of the target charging module with unmatched parameters and unmatched parameter information.
Furthermore, the charging modules in the modular charger are numbered in advance, so that when the current charging parameters of the target charging module are not within the preset parameter range, the numbers and the unmatched parameter information (such as the name of the unmatched parameters, the numerical values before correction and the numerical values after correction) of the target charging module with unmatched parameters are recorded for the user to check, and the user can know which charging modules in the modular charger have changed and are corrected.
As an optional embodiment, the parameter management method further includes:
and outputting the recorded serial number of the target charging module and the unmatched parameter information to a human-computer interaction interface for displaying.
Furthermore, the recorded serial number and the unmatched parameter information of the target charging module can be output to a human-computer interaction interface to be displayed for a user to watch, so that the user can more intuitively know which charging module parameters in the modularized charger are changed and corrected.
It should be noted that there are two implementation ways for parameter management of the modular charger: 1) based on the fact that information interaction is achieved among the plurality of charging modules through communication, one charging module can be selected from the modularized chargers according to a preset master-slave strategy to serve as a master charging module, the rest charging modules serve as slave charging modules, the master charging module obtains a secondary charging module and current charging parameters of the master charging module, and parameter management is conducted on the modularized chargers according to the parameter management method (shown in figure 3); 2) based on interaction of the plurality of charging modules and the upper computer, the upper computer can acquire the current charging parameters of the charging modules so as to perform parameter management on the modular charger according to the parameter management method.
