For example, the battery module may report the real-time status to the cloud device (e.g. server) periodically, and the cloud device analyzes whether the battery needs to be locked by analyzing which unmanned aerial vehicle the battery is used on, and the abnormal record, the battery history record, the battery use duration, etc. in the use process. Battery locks are divided into two types, service locks and fault locks. The following detailed description is provided in connection with the examples
According to the embodiments of the present application, there is provided a method embodiment of a battery control method, it should be noted that the steps shown in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that herein.
Fig. 1 is a control method of a battery according to an embodiment of the present application, as shown in fig. 1, the method including steps S102-108, wherein:
step S102, acquiring state data of a battery module in the electronic equipment, wherein the state data carries an equipment identifier of the electronic equipment where the battery module is located, and the state data comprises: real-time status data;
in some embodiments of the present application, the real-time status data includes: the service time of the battery module is the time between the initial lease time of the battery module and the acquisition time of the real-time state data; for example, 10 in 2019, 1 month, 1 day: 00 is the battery leasing time, and the current time is 2019, 1 month, 21 days, 10:00, and the service time of the battery module is 20×24=480 hours.
The initial lease time of the battery module may also be the first time used for the battery module, where the first time used is the start time of the battery module after the last lease is finished and the last lease time is cleared.
Wherein the battery module may include, but is not limited to: the control circuit is used for controlling the timer to start timing when the battery pack is detected to be electrified (namely, when the battery pack is powered on, the battery pack is powered on), and sending timing duration to the server through the communication module according to a preset time interval.
Of course, the initial rental time of the battery module may also be the time recorded by the system when the battery module is first rented, for example, manually input rental time.
Step S104, determining historical state data corresponding to the equipment identification based on the equipment identification;
step S106, determining a control instruction of the battery module based on at least one of the real-time state data and the history state data, the control instruction being used for executing an operation corresponding to the control instruction on the battery module;
in some embodiments of the present application, the concrete expression of step S106 may be different according to the meaning of the real-time status data or the historical status data:
for example, when the real-time status data includes a usage period of the battery module, step S106 may include: judging whether the using time length of the battery module reaches a preset threshold value or not; and when the using time length reaches a preset threshold value, generating a locking instruction, and taking the locking instruction as a control instruction, wherein the locking instruction is used for controlling the battery module to stop power output.
Also for example: the real-time status data includes: when the battery module is in the current operating state, step S106 includes the following processing procedures: and generating unlocking prompt information when the current working state of the battery module is normal and the historical working state corresponding to the historical collection time which is the latest collection time of the current working state in the historical state data is abnormal, wherein the unlocking prompt information is used for prompting whether to recover the power output of the battery module. When the battery module is detected to be changed from the abnormal working state to normal, unlocking prompt information is generated and sent to the electronic equipment or a control circuit of the battery module so as to unlock the battery module. After the unlocking prompt information is generated, the unlocking prompt information can be sent to the electronic equipment; after receiving the unlocking prompt information, the electronic equipment generates confirmation information for confirmation of a user according to the unlocking prompt information and displays the confirmation information; after receiving a confirmation instruction of a user for confirming the information, the electronic equipment executes unlocking operation on the battery module. The display mode of the confirmation information includes but is not limited to: and (5) confirming a box.
The battery module may also be subjected to a locking operation, such as, for example, before determining a control instruction of the battery module based on at least one of the real-time status data and the historical status data: when the electronic equipment detects that the current working state of the battery module is abnormal, receiving an operation instruction of a user, wherein the abnormal working state comprises the following steps: the battery module fails, or the operation behavior of the battery module is illegal operation behavior; in response to the operation instruction, a locking operation is performed on the battery module, wherein the locking operation is used for controlling the battery module to stop power output. Also for example: when detecting that the current working state of the battery module is abnormal, sending a locking instruction to the electronic device, wherein the locking instruction is used for controlling the electronic device to execute locking operation on the battery module, namely, disconnecting the power output of the battery module, specifically, a switch circuit can be arranged between an output port of the battery module and a load, and when detecting the locking instruction, the switch circuit disconnects a power supply line between the battery module and the load.
Step S108, a control instruction is sent to the electronic equipment.
In some embodiments of the present application, the electronic device includes, but is not limited to: unmanned plane; before the control instruction is sent to the electronic equipment, the operation state of the unmanned aerial vehicle can be obtained, when the operation state is in operation, prompt information for prompting that the using time reaches a preset threshold value is sent to user equipment corresponding to the electronic equipment, and the control instruction is sent to the electronic equipment in a suspended mode. By adopting the scheme, the control instruction (such as the locking instruction) can be sent to the electronic equipment in a suspending way when the unmanned aerial vehicle works, so that the influence of the locking instruction on the working process is avoided.
In addition, after the user equipment receives the prompt information, the lease time of the battery module can be recharged, so that the use time of the battery module can be prolonged.
Wherein, the prompt message further comprises: and the buffer time is used for prompting the battery module to allow additional use, wherein the time is counted at the moment of sending the prompt information, and when the counted time reaches the buffer time, a control instruction is sent to the electronic equipment. For example, the prompt information carries buffer time information of 10 minutes, so that an operator can determine a control strategy of the unmanned aerial vehicle according to actual conditions, for example, return, or return after continuing to operate for 5 minutes.
In some embodiments, after receiving the buffer duration, the drone may determine a temporary job policy from the buffer duration and the job conditions, such as: determining the distance between the current position of the unmanned aerial vehicle and the return location, and determining the return duration corresponding to the distance; when the return time length is smaller than the buffer time length, determining a difference value of the return time length and the buffer time length; determining the remaining operation time of the unmanned aerial vehicle according to the difference value; and controlling the unmanned aerial vehicle to return when the remaining operation time arrives.
In other embodiments of the present application, the real-time status data may include: current operational behavior information of the battery module; the historical state data includes: historical operational behavior information of the battery module; at this time, determining a control instruction of the battery module based on at least one of the real-time status data and the history status data includes: determining a first evaluation index corresponding to current operation behavior information and a second evaluation index corresponding to historical operation behavior information, wherein the first evaluation index and the second evaluation index are used for quantifying the influence degree of faults of the battery module; determining a target evaluation index based on the first evaluation index and the second evaluation index; comparing the target evaluation index with a preset threshold; and generating a control instruction corresponding to the comparison result based on the comparison result.
There are various ways to determine the target evaluation index, for example: summing the first evaluation index and the second evaluation index, and taking the sum value as a target evaluation index; for another example, the first evaluation index and the second evaluation index are assigned respective weights, and then the target evaluation index is determined based on the weights and the respective evaluation index values, specifically: the first evaluation index and the second evaluation index are a and b respectively, wherein weights of the first evaluation index and the second evaluation index are c and d respectively, and then the target evaluation index is (a×b+c×d), wherein the weight of the second evaluation index can be determined according to the type of the historical operation behavior information, for example, the degree of influence of the overcharge behavior of the battery on the service life of the battery is relatively large, a relatively large weight can be allocated to the second evaluation index, and the battery is charged when the battery is not completely discharged (for example, the residual electric quantity of the battery is not 0 and is smaller than a certain threshold value), and at the moment, the influence on the service life of the battery is relatively small, and a relatively small weight can be allocated to the second evaluation index.
Wherein the target evaluation index and the preset threshold value may be compared by: comparing the target evaluation value with a first threshold value in the preset threshold values; at this time, a control instruction corresponding to the comparison result is generated based on the comparison result by: generating a lock instruction for controlling the battery module to stop the power output when the target evaluation value is greater than the first threshold value;
alternatively, the target evaluation index may also be compared with a preset threshold by: comparing the target evaluation value with a second threshold value in the preset threshold values; at this time, a control instruction corresponding to the comparison result is generated based on the comparison result by: generating a control instruction for limiting the single-use duration of the battery module when the target evaluation value is greater than the second threshold value; the control instruction includes, but is not limited to, a duration of the battery module during a single operation, for example, if a current state of the battery is abnormal and if the battery is used continuously for a long time, an influence on a service life of the battery is generated, and at this time, an instruction for limiting the duration of the single use is generated.
Alternatively, the target evaluation index may also be compared with a preset threshold by: comparing the target evaluation value with a third threshold value in the preset threshold values; at this time, a control instruction corresponding to the comparison result is generated based on the comparison result by: and when the target evaluation value is larger than a third threshold value, generating a control instruction for improving the reporting frequency of the state data.
When the battery risk assessment is achieved, the battery safety coefficient can be determined according to the operation record of the battery, and meanwhile, each user battery is scored, for example, whether misoperation exists or not can be determined from the operation record, the misoperation times can be recorded, the misoperation environment can be recorded, and the battery is scored by buckling 5 points once each operation is improper. As another example, if the operator overcharges and overdischages multiple times during use of the battery, the corresponding score is deducted. As another example, if the load is large, the corresponding score is snapped off. In the risk assessment process, it may be determined from the job record whether there is a risk of fire, specifically:
