The following first presents an exemplary description of what embodiments of the present application may relate to.

Please refer to fig. 1, which is a schematic diagram of a power swapping system according to an embodiment of the present disclosure. As shown in fig. 1, the system includes a power exchange cabinet 11, a terminal device 12, and a server 13. The power exchange cabinet 11 and the terminal equipment 12 can be in communication connection with the server 13. Terminal device 12 may illustratively be a cell phone or tablet or the like. The switchboard 11 may comprise a touch screen for displaying relevant information to the user, e.g. a two-dimensional code or the like; the touch control device can also be used for receiving touch control operation of a user and executing corresponding actions in response to the touch control operation, for example, opening a bin door of an empty bin and the like. Further, the battery changing cabinet 11 includes a plurality of bins for storing batteries, and for example, referring to a schematic block diagram of the battery changing cabinet shown in fig. 2, the battery changing cabinet 21 includes a bin 211, a bin 212, a bin 213, a bin 214, a bin 215, a bin 216, and a bin 217. After the user inserts the battery in the storehouse, trade the battery cabinet and can charge to the battery.

Based on the battery swapping system architecture of fig. 1, the battery swapping process may be exemplarily as follows:

first, a user scans a two-dimensional code displayed on the switchboard 11 through the terminal device 12 (e.g., a mobile phone). After scanning the two-dimensional code, the terminal device 12 sends a battery swapping request to the server 13; after receiving the battery swapping request from the terminal device 12, the server 13 sends a battery swapping instruction to the battery swapping cabinet 11 according to related information carried by the battery swapping request, for example, identification information of the battery swapping cabinet 11.

After receiving a power change instruction from the server, the power change cabinet 11 queries the bins in the empty bin state at the current time in response to the power change instruction, selects one empty bin from the bins in the empty bin state, and controls the empty bin to open the bin door.

After the power exchange cabinet 11 opens the door of the empty bin, the user can put the battery detached from the electric vehicle into the target empty bin and close the door of the empty bin.

When the switch cabinet 11 detects that the bin door of the empty bin is closed, one bin is selected from the bins storing the fully charged batteries, and the bin of the bin is opened. And after the bin door is opened, the user takes out the fully charged battery to load the electric vehicle, and closes the bin door. Thus, a power conversion process is completed.

In the above-mentioned battery replacement process, the battery replacement cabinet 11 needs to know the state of each bin, that is, it needs to know which bin is empty and which bin is a bin with a fully charged battery.

In a specific application, the main control module in the battery replacement cabinet 11 can obtain the state of each bin through information reported by a Power Management System (PMS) of each bin.

Each compartment of the power change cabinet 11 is provided with a PMS as a control panel of each compartment. The PMS is mainly used for acquiring battery information and reporting the battery information to a main control module (namely an upper computer) and can also be used for controlling a charger to charge batteries in a bin.

Each Battery has a Battery Management System (BMS) for data acquisition, Management, and control of the Battery. The BMS serves as a control board for the battery.

After the user inserts the battery into the empty compartment of the power distribution cabinet, the PMS of the compartment may communicate with the BMS for the battery to read battery information, determine whether the battery is on-line, etc.

For example, referring to the schematic block diagram of the structure of the power conversion cabinet shown in fig. 3, the power conversion cabinet may include a main control module 33, a PMS31, and a BMS 32. There is one PMS31 for each bay, and BMS32 is the control board for the batteries in the bay. Communication between the PMS31 and the BMS32 is performed via a can (controller Area network) bus.

After the user inserts the battery into the empty bin, the PMS CAN continuously send a query command to the BMS of the battery through the CAN bus to confirm whether the battery is on line or not, and report the on-line state of the battery to the power change cabinet.

And after receiving the query command from the PMS, the BMS responds according to the data protocol to return response data to the PMS.

If the PMS receives response data of the BMS of the battery, the battery is considered to be on-line, namely the battery is considered to be in the bin; if the response data of the BMS of the battery is not received, the battery is considered to be not on-line, i.e., the battery is considered not to be in the compartment, i.e., the compartment is considered to be an empty compartment.

Normally, the BMS of the battery responds to the PMS after receiving the query command of the PMS. However, if a battery fails or the battery is under-voltage and sleeps, the battery will not respond to the PMS.

Illustratively, the BMS acquires the battery voltage through the ADC, and determines that the current battery voltage is less than a certain voltage threshold, and considers that the battery is under-voltage. And, under the undervoltage condition, the battery has no current for more than 15 minutes, and the battery can enter the dormant state. In the dormant state, the battery CAN close the MOS tube and close the CAN bus module. At this time, the BMS and the PMS cannot communicate through the CAN bus, and after the PMS sends the query command to the BMS, the BMS will not respond, and the PMS will not receive BMS response data. Or, when the fault occurs in the PMS terminal or the CAN module of the BMS terminal, the communication between the PMS and the BMS is disabled, and the PMS does not receive BMS response data.

In these cases, the PMS may assume that the battery is not in the bin due to the failure to receive BMS response data. But in practice the batteries are in the compartment. Therefore, after the main control module of the power transformation cabinet receives the empty bin state information reported by the PMS, the empty bin of the bin loaded with the battery is recorded by mistake. Therefore, when the user exchanges electricity, the main control module of the electricity exchange cabinet can pop up the bin with the battery as an empty bin to the user, and the battery can be lost.

For example, for the power distribution cabinet 21 shown in fig. 2, assuming that the battery in the compartment 213 is under-voltage and dormant, the PMS in the compartment 213 sends a query command to the BMS of the battery in the compartment, and the BMS cannot send response data to the PMS because the battery is dormant. At this time, the PMS reports the empty bin state to the main control module if the PMS cannot receive the BMS response data within a certain time period. And after receiving the empty bin state reported by the PMS, the main control module changes the state of the bin 213 into an empty bin.

After scanning the two-dimensional code displayed by the power exchange cabinet 21 through the mobile phone, the user sends a power exchange instruction to the power exchange cabinet 21 by requesting the background server. The main control module of the power change cabinet 21 responds to the power change instruction and inquires that the bin 213 is currently in the empty bin state, and then pops the bin 213 as an empty bin to the user, that is, opens the bin door of the bin 213. But actually, the compartment 213 is stored with batteries, and the batteries in the compartment 213 may be lost when the compartment door is opened.

In order to solve the problem that the battery of the power changing cabinet is lost, the embodiment of the application provides a battery anti-loss scheme of the power changing cabinet. According to the scheme, when the battery is in the cabin, if the PMS cannot receive BMS response data, the cabin is not considered to be an empty cabin, the empty cabin is not reported to the main control module, and a fault is reported to the main control module. In this way, the master control module can disable the failed bin to prevent the battery from being lost.

Referring to fig. 4, a schematic flow chart of a battery loss prevention method for a power conversion cabinet provided in an embodiment of the present application may be applied to a PMS of each bin in the power conversion cabinet, and the method may include the following steps:

step S401, the PMS sends a query command to the battery.

It will be appreciated that after the user inserts the battery into the compartment, the PMS will continuously send a query command to the battery's BMS to confirm that the battery is on-line, i.e., whether the battery is in the compartment.

Typically, there is a connection line between the PMS and the BMS, and this continuous line has an INT signal. When the battery is just inserted into the cabin of the power exchange cabinet, the BMS of the battery wakes up from the sleep state after detecting the INT signal. At the same time, the PMS also receives the VCC signal transmitted by the BMS. The PMS, upon receiving the VCC signal from the BMS, will then continuously query whether there is a battery in the compartment.

That is, in some embodiments, prior to sending the query command to the battery, the method further comprises: after the battery is inserted into the front compartment, the PMS receives a voltage signal (i.e., VCC signal) of the battery; in response to the voltage signal, a step of sending a query command to the battery is entered.

In some embodiments, the query command is a BMS firmware version query command, and the response data includes a firmware version number. Namely, the PMS transmits a BMS firmware version query command to the BMS, and the BMS transmits a version number to the PMS in response to the query command.

Step S402, if the response data returned aiming at the query command is not received, the PMS determines whether the bin gate of the current bin is opened within a preset time period, wherein the preset time period is a time period between a time point when the battery is inserted into the current bin and the current time point.

It can be understood that, when the PMS sends the query command to the BMS, the transmission time point of the query command may be recorded, and whether response data returned by the BMS is not received due to timeout may be determined based on the recorded transmission time point and the current time point. And if the response data returned by the BMS is not received in the overtime, the response data returned aiming at the query command is not received.

When the PMS judges that response data returned aiming at the query command are not received, whether the bin gate is opened within a preset time period or not is further judged, namely whether the bin gate is opened from the time point when the battery is inserted into the bin to the current time point or not is further judged. If the bin door is opened, the battery in the bin is considered to be taken out, and the bin is an empty bin due to the fact that the BMS response data are not received; on the contrary, if the bin door is not opened, the battery in the bin is not taken out, the reason that the BMS response data is not received is the reason that the battery is in failure and the like, and the bin is not considered to be an empty bin but is considered to be a failed bin.

Step S403, if the door of the current cabin is not opened within a preset time period, the PMS reports fault information, and the fault information is used for representing that the current cabin is in a fault state.

It should be noted that, after receiving the fault information reported by the PMS, the main control module of the power conversion cabinet changes the state of the corresponding bin into a fault state. In a fault condition, the bin is not allowed to open as an empty bin. Normally, a failure state of a warehouse requires the maintenance personnel to handle the failure on site.

It can be understood that the main control module allocates an address to the PMS of each bin, and can know the fault information reported by the PMS of which bin according to the address of the PMS, and further know which bin needs to be forbidden.

The PMS of each cabin can also be used for opening the cabin door according to the cabin opening instruction of the main control module. Specifically, when the main control module needs to open the bin door of a certain bin, a bin opening instruction is issued to the PMS of the bin, and after receiving the bin opening instruction, the PMS controls the bin door to be opened. Therefore, the PMS may determine whether the bin door has been opened within the preset time period by inquiring whether a bin opening command is received within the preset time period. If the bin opening instruction is received within the preset time period, the bin gate is considered to be opened within the preset time period, otherwise, the bin gate is considered not to be opened within the preset time period.

It is worth noting that upon failure to receive the BMS response data, the PMS does not consider the compartment to be empty, but rather further confirms whether a battery is stored in the compartment. If the battery is stored in the bin, the battery can not receive BMS response data, the battery is considered to be a fault bin, the main control module can further forbid the bin for the bin, and in the battery replacement process, the main control module does not pop the fault bin as an empty bin for a user, so that the battery can not be lost.

Optionally, the method may further include step S404, if the bin door of the current bin is opened within a preset time period, the PMS reports empty bin information, where the empty bin information is used to represent that the current bin is in an empty bin state.

As can be seen from the above discussion, the PMS further confirms whether the door has been opened when the BMS response data is not received. If the bin door is opened, the bin is considered to be an empty bin, and empty bin information is reported to the main control module.

Optionally, the method may further include step S405, if response data returned for the query command is received, the PMS reports the information in the bin, where the information in the bin is used to represent that a battery is stored in the bin.

And if the PMS receives response data returned by the BMS, the PMS considers that a battery is stored in the bin and reports the information in the bin to the main control module.

According to the technical scheme, when the response data returned by the battery for the query command cannot be received, the current bin cannot be directly considered as an empty bin, and the empty bin information is reported, but whether the battery is in the bin is further judged by whether the bin door is opened within the preset time period, if the bin door is not opened within the preset time period, the battery is not taken out from the time point when the battery is inserted into the bin to the current time point, and then the current bin is determined not to be the empty bin, and the fault information is reported. Like this, trade the electric cabinet and can forbid the back in storehouse according to fault information, can not open the storehouse that is in the fault condition at the electricity changing in-process, can not pop out the storehouse that has the battery for the user as the empty storehouse promptly, and then can not appear the battery and lose.

The power transformation cabinet is provided with a plurality of bins, each bin is provided with one PMS, and each PMS executes the flow shown in the figure 4 so as to report information to the main control module. And the main control module obtains the battery information of each bin according to the information reported by the PMS of each bin.

In the embodiment of the application, when the master control module receives the fault information reported by the PMS, the state of the bin is changed into the fault state. Based on this, the swap procedure may be exemplarily as follows:

firstly, a user scans a two-dimensional code of the power change cabinet through the terminal device, so that the terminal device sends a power change request to the server. And the server responds to the battery swapping request and sends a battery swapping instruction to the battery swapping cabinet. Of course, the user may trigger the power swapping instruction in other ways. For example, a user may input a power swapping instruction to the power swapping cabinet through a touch screen of the power swapping cabinet.

After the battery replacement cabinet obtains the battery replacement instruction, the current state of each bin is inquired in response to the battery replacement instruction. And selecting one empty bin from the bins in the empty bin state to be ejected to the user. At this time, the bin in the fault state is not popped out as an empty bin to the user, so that the battery is not lost in case that the PMS cannot receive the BMS response data while the battery is in the bin.

The user inserts the low-battery cell of following the electric motor car dismantlement into the empty storehouse of popping out to close the door. After the main control module of the power exchange cabinet detects that the bin door is closed, a fully charged battery bin is popped up for a user, so that the user can take out the fully charged battery and install the fully charged battery on the electric vehicle.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
