Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings 1-2 and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The embodiment of the application discloses an intelligent charging cabin with an identification function.
Referring to fig. 1, the intelligent charging bay with the identification function includes a charging circuit 1, a detection circuit 2, and a processing module 3. The application can automatically identify the type of the battery to be charged, and adjust the setting of the charging cabin after determining the type of the battery to match the charging parameters corresponding to the type of the battery, so that the charging process can be automated and intelligent.
Wherein the detection circuit 2 comprises a first part 4 arranged in the battery to be charged and a second part 5 arranged in the charging cabin. When the battery to be charged is placed in the appointed position of the charging cabin, the detection circuit 2 formed by connecting the first part 4 and the second part 5 is used for collecting voltage information of the battery to be charged in different states and outputting the voltage information.
Specifically, the first portion 4 includes three connection terminals provided at the end portion of the battery to be charged, which is connected to the charging compartment, and a first resistor R1. The three connecting terminals are a battery positive terminal, a battery negative terminal and an identity recognition terminal respectively. Wherein the battery positive terminal and the identification terminal are connected through a first resistor R1. Note that, the resistance value of the first resistor R1 is different in different types of batteries. That is, by detecting the resistance value of the first resistor R1 of the battery to be charged, the model information of the current battery to be charged can be determined.
Three wiring terminals corresponding to the battery positive terminal, the battery negative terminal and the identity recognition terminal one by one are arranged in the charging cabin. The terminal corresponding to the positive terminal of the battery is connected to the charging circuit 1. The charging circuit 1 is used for charging a battery to be charged. The present application does not relate to an improvement of the charging circuit 1, and therefore a detailed description thereof will not be given.
The second part 5 comprises a second resistor R2, a third resistor R3 and a voltage acquisition unit 6. The connecting terminal corresponding to the negative end of the battery is connected with the connecting terminal corresponding to the identity recognition end through a second resistor R2, and the connecting terminal corresponding to the negative end of the battery is grounded. One end of the third resistor R3 is connected with a wiring terminal corresponding to the identity recognition end, and the other end is a free end. The voltage acquisition unit 6 is connected with a wiring terminal corresponding to the identity recognition end, and is used for acquiring the voltage value of the wiring terminal corresponding to the identity recognition end and outputting voltage information. Preferably, the voltage acquisition unit 6 is a digital-to-analog converter.
The processing module 3 is connected with the detection circuit 2, and is used for controlling the connection mode in the detection circuit 2, identifying the model information of the battery to be charged according to the received voltage information, and retrieving the parameter comparison table to adjust the working mode to a mode conforming to the charging parameters corresponding to the model information.
It can be appreciated that, in order to determine the resistance value of the first resistor R1 to identify the model information of the battery to be charged, the detection circuit 2 needs to control it in cooperation with the processing module 3. Specifically, first, the free end of the third resistor R3 needs to be set to a high configuration, i.e., floating. Then, the voltage information acquired by the voltage acquisition unit 6 at this time is acquired. Then, the free end of the third resistor R3 is grounded to obtain the voltage information of the voltage acquisition.
Further, when the processing module 3 acquires the first acquired voltage information and the second acquired voltage information, the resistance value of the first resistor R1 may be determined according to the first acquired voltage information and the second acquired voltage information by using a voltage division principle. And then, determining the model information of the battery to be charged according to the resistance value of the first resistor R1. Of course, after determining the resistance value of the first resistor R1, the current battery voltage may also be determined according to the resistance value of the first resistor R1 to monitor the state of charge of the battery. Wherein the voltage information acquired for the first time isThe voltage information acquired for the second time is +.>V is the cell voltage of the current cell. Based on the first acquired voltage information andthe formula for determining the resistance value of the first resistor R1 from the second acquired voltage information is +.>It should be noted that, in order to simplify the complexity of the calculation, the present application preferably sets the resistance value of the second resistor R2 to the same resistance value as the resistance value of the third resistor R3.
After the model information of the battery to be charged is determined, the charging parameters corresponding to the model information of the battery to be charged can be determined according to the called parameter comparison table. The parameter comparison table comprises model information, resistance values of the first resistors R1 corresponding to the model information one by one, and charging parameters corresponding to the model information one by one. In some specific embodiments, the parameter lookup table may be pre-stored in a storage device having a storage function, such as a memory.
Of course, the model information referred to in the parameter lookup table is not comprehensive, that is, when the processing module 3 recognizes the model information of the battery to be charged, the corresponding charging parameters are not matched in the parameter lookup table. For the above case, it is necessary to acquire the manually input charging parameters, so that the charging pod adjusts the charging mode according to the input charging parameters. Specifically, after the charging cabin is connected with the APP matched with the charging cabin, a user can set charging parameters through the APP independently. Meanwhile, the processing module 3 may store the set charging parameters to update the parameter comparison table.
Furthermore, the problem of charging safety may be considered in the charging process. For this reason, when the charging parameter input by the user is acquired, it is also detected whether the value of the charging parameter is within the abnormal parameter range. If the value of the charging parameter is in the abnormal parameter range, an alarm is given to prompt the user to modify. Wherein, for different models of batteries, the corresponding abnormal parameter ranges are also different. The outlier parameter range may be empirically obtained by one skilled in the relevant art.
According to the technical scheme, the resistance value of the first resistor R1 can be detected to determine the model information of the battery to be charged, and then the charging parameters can be matched for the battery automatically. The charging device is improved on the basis, the type information of the battery to be charged can be determined by determining the resistance value of the first resistor R1, the charging parameters can be automatically matched with the type information, the battery temperature of the battery to be charged can be detected in real time in the charging process, and the battery state of the battery to be charged in the charging process can be monitored.
