Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1, fig. 1 is a schematic block diagram of a charging system according to an embodiment of the present disclosure. The charging system 100 includes a smart battery 10 and a charger 20. The charger 20 is used to connect an external power source to charge the smart battery 10, and the smart battery 10 is used to power electronic devices, such as a movable platform and a load mounted on the movable platform.

In the embodiment of the present application, the smart Battery 10 includes a Battery Management System (BMS) including a Micro Controller Unit (MCU) and a discharge resistor connected to the Battery through a discharge circuit for discharging the Battery under the control of the micro controller Unit.

The micro control unit is used for acquiring and processing battery parameters of the battery, wherein the battery parameters comprise charging current, charging voltage, charging time, discharging current, discharging time, battery temperature, constant voltage charging time, constant voltage charging capacity, charging and discharging capacity ratio and the like.

The battery management system may be used to estimate a State of Charge (SOC), i.e., a remaining battery capacity, to ensure that the SOC is maintained within a reasonable range, and to prevent damage to the battery due to overcharge or overdischarge.

In the process of charging and discharging the battery, the battery management system can also acquire the voltage, the temperature, the charging and discharging current and the like of the battery in real time, so that the phenomenon of overcharge or overdischarge of the battery is prevented.

Wherein, the movable platform comprises an aircraft, a robot, an electric vehicle or an automatic unmanned vehicle and the like.

For example, the intelligent battery 10 supplies power to a motor of the aircraft to control the motor propeller to rotate, so that the aircraft can fly; for another example, the smart battery 10 supplies power to a camera mounted on an aircraft for realizing aerial photography and the like.

Wherein, this aircraft includes unmanned aerial vehicle, and this unmanned aerial vehicle includes rotor type unmanned aerial vehicle, for example four rotor type unmanned aerial vehicle, six rotor type unmanned aerial vehicle, eight rotor type unmanned aerial vehicle, also can be fixed wing unmanned aerial vehicle, can also be the combination of rotor type and fixed wing unmanned aerial vehicle, does not do the injecing here.

The robot comprises an educational robot, a Mecanum wheel omnidirectional chassis is used, a plurality of intelligent armors are arranged on the whole body, and each intelligent armor is internally provided with a hitting detection module which can rapidly detect physical hitting. Simultaneously still include the diaxon cloud platform, can rotate in a flexible way, cooperation transmitter accuracy, stability, launch crystal bullet or infrared light beam in succession, cooperation trajectory light efficiency gives the user more real shooting experience.

Therefore, the importance of the battery to the movable platform can affect the safety of the operation of the movable platform if the battery is abnormal.

However, when the existing battery, such as a lithium ion battery, is used, some internal short circuits, such as micro short circuits, often occur, which may cause accidents such as battery failure and fire. Because the internal short circuit of the battery has certain contingency, the detection is difficult, and some related detection circuits are used for short circuit detection at present, but the hardware cost is increased. Meanwhile, the problem that effective protection cannot be carried out after short circuit is detected exists.

Therefore, the embodiment of the application provides a battery control method, an intelligent battery, a charging system, a movable assembly and a storage medium, wherein the battery control method can be applied to the intelligent battery, and when the battery is determined to be short-circuited, the battery is effectively protected, so that the use safety of the battery is improved.

Referring to fig. 2, fig. 2 is a schematic flowchart illustrating steps of a battery control method according to an embodiment of the present disclosure. The battery control method can be applied to intelligent batteries, so that the batteries can identify whether the batteries are short-circuited or not, and the use/storage safety of the batteries is improved. The method may also be applied in electronic devices capable of communicating with a battery, such as chargers, battery stewards, control terminals, mobile platforms. The electronic equipment can identify whether the battery is short-circuited on line in the using process and effectively protect the battery and/or the electronic equipment.

As shown in fig. 2, the battery control method includes steps S101 to S104.

And S101, acquiring battery parameters of the battery.

The battery parameters comprise at least one of constant voltage charging time, constant voltage charging capacity, charging and discharging capacity ratio and battery temperature.

In particular, battery parameters collected by the battery circuit may be obtained. For example, when the battery is charged, a constant voltage charging stage is started, and the constant voltage charging time is obtained by acquiring the time of the constant voltage charging stage. For another example, the temperature of the battery collected by the temperature sensor may be acquired, and the temperature sensor may be provided on the surface of the battery or inside the battery. The battery circuit may communicate with a temperature sensor to obtain battery temperature data.

Specifically, the battery parameters obtained through calculation may also be obtained, for example, the charge-discharge capacity, that is, the charge capacity and the discharge capacity of the battery may be obtained through ampere-hour integral calculation, and then the charge-discharge capacity ratio may be calculated according to the charge capacity and the discharge capacity.

And S102, determining whether the battery is short-circuited or not according to the battery parameters.

Whether the battery is short-circuited can be determined by judging whether the battery parameter is abnormal. For example, whether the battery parameter is abnormal is determined by comparing with a standard parameter, wherein the standard parameter is a parameter when the battery is normal.

For example, whether the battery is short-circuited is determined according to battery parameters, specifically: acquiring standard parameters of a battery; and determining whether the battery is short-circuited according to the difference between the battery parameter and the standard parameter.

For example, determining whether the difference between the battery parameter and the standard parameter is within a preset range; if the difference between the battery parameter and the standard parameter is within a preset range, determining that the battery is not short-circuited; and if the difference between the battery parameter and the standard parameter is not in the preset range, determining that the battery is short-circuited. Whether the short circuit of the battery occurs can be accurately determined through the preset range.

The preset range is set according to the type of the battery, the preset ranges of different types of batteries are different, and the different types of batteries comprise different battery capacity or different battery core materials, such as lithium ion batteries and lead storage batteries.

For another example, determining whether the battery parameter is greater than a standard parameter; if the battery parameter is larger than the standard parameter, determining that the battery is short-circuited; and if the battery parameter is less than or equal to the standard parameter, determining that the battery is not short-circuited. It is thus possible to quickly determine whether a short circuit has occurred in the battery.

In some embodiments, if the battery parameter is a constant voltage charging time, the standard parameter is a standard constant voltage charging time. Determining whether the battery is short-circuited, specifically: determining whether the constant voltage charging time is greater than a standard constant voltage charging time; if the constant voltage charging time is longer than the standard constant voltage charging time, determining that the battery is short-circuited; and if the constant voltage charging time is less than or equal to the standard constant voltage charging time, determining that the battery is not short-circuited.

Since the battery charging generally includes a constant current charging stage and a constant voltage charging stage, the charging time in the constant voltage charging stage is substantially the same for the same type of battery with a fixed capacity, and thus it can be determined whether the battery is short-circuited according to the constant voltage charging time in the constant voltage charging stage.

For example, the lithium battery is charged by constant current and constant voltage, the time of the constant voltage charging stage is generally 20-30 minutes, and when the battery is in a micro short circuit, the time of the constant voltage charging of the battery is greatly prolonged, which may be 40-50 minutes or several hours. Therefore, whether the battery is slightly short-circuited can be judged by detecting the charging time of the constant-voltage charging stage of the battery.

In some embodiments, if the battery parameter is a constant voltage charge capacity, the standard parameter is a standard constant voltage charge capacity. Determining whether the battery is short-circuited, specifically: determining whether the constant voltage charging capacity is greater than a standard constant voltage charging capacity; if the constant voltage charging capacity is larger than the standard constant voltage charging capacity, determining that the battery is short-circuited; and if the constant voltage charging capacity is less than or equal to the standard constant voltage charging capacity, determining that the battery is not short-circuited.

When normal state, the constant voltage charge capacity of battery is fixed, if appear the short circuit, the battery can have the electric leakage phenomenon, and then leads to the constant voltage charge capacity of battery great, can be greater than the constant voltage charge capacity of battery when normal state far away even. Therefore, it is possible to quickly and accurately determine whether a short circuit, such as a micro short circuit, occurs in the battery through the constant voltage charging capacity.

For example, if the battery parameter is the charge-discharge capacity ratio, the standard parameter is the standard charge-discharge capacity ratio. Determining whether the battery is short-circuited, specifically: determining whether the charge-discharge capacity ratio is greater than a standard charge-discharge capacity ratio; if the charge-discharge capacity ratio is larger than the standard charge-discharge capacity ratio, determining that the battery is short-circuited; and if the charge-discharge capacity ratio is smaller than or equal to the standard charge-discharge capacity ratio, determining that the battery is not short-circuited.

In a normal state, the charge-discharge capacity ratio of the battery is generally in a fixed range, and the charge-discharge capacity ratio of the battery with the short circuit is larger, so that whether the battery has the short circuit or not can be determined according to the change of the charge-discharge capacity ratio.

For example, in a lithium ion battery, the charge-discharge capacity ratio fluctuates within the range of 1.01-1.05 in a normal state, and in a lithium ion battery with a micro short circuit, the charge-discharge capacity ratio is far larger than 1, so that whether the battery is short-circuited or not is determined according to the change of the charge-discharge capacity ratio. For example, when the ratio of the charge-discharge capacity is greater than 1.1, it can be determined that the battery has a micro short circuit.

In some embodiments, in order to accurately determine that the battery is short-circuited, a charging voltage and a charging time corresponding to the charging of the battery may also be obtained, and the charging voltage and the charging time are used to represent battery parameters of the battery for determining whether the battery is short-circuited.

Accordingly, whether the battery is short-circuited or not is determined, and whether the battery is short-circuited or not can be determined according to the charging voltage and the charging time corresponding to the charging of the battery.

Since the change trend of the charging voltage along with the charging time when the battery is short-circuited is different from the change trend of the charging voltage along with the charging time in the normal state, whether the battery is short-circuited can be determined according to the charging voltage and the charging time.

In some embodiments, the battery temperature rises to a certain threshold, often caused by a short circuit of the battery, and it may be determined that the battery may be shorted when the battery temperature rises to a certain threshold range by detecting the battery temperature.

As shown in fig. 3, fig. 3 is a graph showing the variation of the charging voltage of the battery with short circuit along with the charging time; as shown in fig. 4, fig. 4 is a graph showing the variation of the charging voltage of the battery with the charging time in the normal state. Therefore, whether the short circuit phenomenon occurs in the battery can be determined according to the change trend graph corresponding to the charging voltage and the charging time.

As can be seen from fig. 3 and 4, the difference is more apparent in the constant voltage charging stage in order to quickly and accurately determine whether the battery is short-circuited. The obtained charging voltage at least comprises a constant voltage charging voltage; accordingly, the charging time includes at least a constant voltage charging time.

It should be noted that the constant voltage charging voltage and the constant voltage charging time are the charging voltage and the charging time when the battery enters the constant voltage charging stage.

S103, if the battery is short-circuited, determining a battery protection strategy corresponding to the short-circuited battery.

In some embodiments, if the battery is short-circuited, determining a battery protection strategy corresponding to the short-circuited battery in the multi-stage battery protection strategies according to the multi-stage battery protection strategies. The multi-stage battery protection strategy may also be related to other abnormal conditions of the battery, for example, there may also be a battery protection strategy corresponding to the occurrence of the over-temperature of the battery in the multi-stage battery protection strategy, and there may also be a battery protection strategy corresponding to the occurrence of the leakage current of the battery in the multi-stage battery protection strategy.

The battery protection strategy corresponding to the short circuit of the battery may be a preset battery protection strategy, and the battery protection strategy may be a strategy mode for protecting the battery when the battery is short-circuited.

Wherein the battery protection strategy may include at least one of: and discharging the battery to a preset voltage range corresponding to the safe storage of the battery, and controlling the battery to be in a locking state.

Of course, the battery protection strategy may also include other strategy approaches. For example, the prompt message is output to prompt for processing the battery according to the prompt message, and the prompt message may be a voice prompt message, a text prompt message, an indicator light prompt message, or the like.

In some embodiments, the battery protection strategies include multiple battery protection strategies, each level of the multiple battery protection strategies has different protection modes, and short-circuit degrees of short circuits corresponding to each level of the multiple battery protection strategies are different, so that the corresponding protection strategies are determined according to the short-circuit degrees of the batteries, and the batteries are effectively and reasonably protected.

Illustratively, the multi-level battery protection strategy includes at least one of: a first level battery protection strategy, a second level battery protection strategy, and a third level battery protection strategy.

Wherein the first level battery protection strategy comprises: and outputting prompt information for prompting the user to repair and maintain.

Wherein the second level battery protection strategy comprises: and controlling the battery to enter a self-discharge program to discharge the battery, and/or outputting prompt information for prompting a user that the battery is unusable.

Wherein the third level battery protection strategy comprises: and controlling the battery to be in a locked state, and/or outputting prompt information for prompting a user that the battery is scrapped.

Specifically, the short circuit degree corresponding to the short circuit of the battery may be determined first; and determining a multi-stage battery protection strategy corresponding to the short circuit according to the short circuit degree.

For example, the short-circuit degree includes a short-circuit degree a, a short-circuit degree b, and a short-circuit degree c, and corresponds to the first-stage battery protection strategy, the second-stage battery protection strategy, and the third-stage battery protection strategy, respectively.

Wherein, the determining the short-circuit degree of the short circuit specifically comprises: and determining the difference degree between the battery parameter and the standard parameter, and determining the short circuit degree according to the difference degree.

Illustratively, the constant voltage charging time of the battery exceeds the standard constant voltage charging time by 10 minutes, defined as the short-circuit degree a; the constant voltage charging time of the battery exceeds the standard constant voltage charging time by 20 minutes and is defined as the short circuit degree b; the constant voltage charging time of the battery exceeds the standard constant voltage charging time by 30 minutes, which is defined as a short circuit degree c.

For example, if the constant voltage charging time of the battery is 45 minutes and the standard constant voltage charging time is 20 minutes, it may be determined that the short-circuit degree of the battery is the short-circuit degree b, and therefore, it is determined that the multi-stage battery protection strategy corresponding to the short-circuit of the battery is the second-stage battery protection strategy.

And S104, controlling the battery to execute the battery protection strategy.

Specifically, discharging the battery through a preset discharge resistor in the battery management system to a preset voltage range; and/or controlling a charging switch and a discharging switch of the battery to be in an off state so that the battery is in a locking state, namely permanently disabled.

The preset voltage range is a safe voltage range, and a range value near 0V may be set, and the specific range value is not limited herein.

In some embodiments, other battery protection strategies may also be employed, such as outputting a prompt to prompt the user that the battery is shorted. The prompting message includes voice prompting message, text prompting message and/or indicating lamp prompting message, such as lamp language composed of different LEDs to prompt the user that the battery is short-circuited.

It can be understood that when the battery is in a charging state, the battery protection strategy is executed after the battery is detected to be short-circuited and the charging is stopped; the battery protection strategy is implemented while securing a mobile platform using the battery when the battery is in a discharged state.

For example, as shown in fig. 5, if it is determined that the battery is short-circuited during the charging process of the battery, the charging of the battery is stopped, and the battery protection strategy is executed. Wherein, stopping charging the battery, can send the control signal to the charging switch circuit for the little control unit, in order to make the charging switch circuit disconnect; it is of course also possible for the micro control unit to send a control signal to the charger to stop the charging of the charger.

For example, according to the constant voltage charging time or the charging voltage and the corresponding charging time, it is determined that the intelligent battery is short-circuited, the battery is stopped from being continuously charged, and the battery is discharged to a preset voltage range, or the battery is controlled to be in a locked state. The battery with short circuit is prevented from being used by users, thereby improving the use safety of the battery.

For example, as shown in fig. 6, the unmanned aerial vehicle is equipped with a smart battery, and during the flight of the unmanned aerial vehicle, the micro control unit of the smart battery determines that the battery is short-circuited according to the battery parameters, for example, determines that the battery is short-circuited according to the charge-discharge capacity ratio, and the micro control unit of the smart battery sends an instruction for instructing the unmanned aerial vehicle to return to the flight controller of the unmanned aerial vehicle. And after receiving the instruction, the flight controller controls the aircraft to return and feeds back the instruction to the micro control unit of the intelligent battery. And the micro control unit executes the battery protection strategy after receiving the feedback information.

Certainly, the micro control unit of intelligent battery sends the instruction that is used for instructing unmanned aerial vehicle to return to the flight controller of unmanned aerial vehicle, and flight controller sends this instruction to ground control end again, knows by the user that the battery sends the instruction of returning to the journey to give flight controller after the short circuit appears, and flight controller begins to return to the journey after receiving the instruction of returning to the journey of ground control end.

Specifically, can be when unmanned aerial vehicle returns to voyage or when returning to the voyage to end, discharge the battery to predetermineeing the voltage range to control the battery and be in the lock state when not having man-machine to stop the operation, can improve the safety in utilization of battery from this to unmanned aerial vehicle's flight security has been ensured.

It is to be understood that, if the battery protection strategy further includes a multi-level battery protection strategy, the battery may also be controlled to execute the determined multi-level battery protection strategy.

For example, if the determined multi-level battery protection strategy corresponding to the short circuit of the battery is the second-level battery protection strategy, the battery may be controlled to enter a self-discharge program to discharge the battery, and/or a prompt message for prompting a user that the battery is unusable is output.

In some embodiments, after controlling the battery to execute the battery protection strategy, the battery control method further includes: and when the battery is detected to be connected to the movable platform, outputting alarm prompt information to prompt a user that the battery is short-circuited. The safety of the battery can be ensured, and the operation safety of the movable platform can be improved.

In some embodiments, when the method is applied to the intelligent battery, the intelligent battery can accurately and quickly identify whether the battery is short-circuited or not, and when the battery is short-circuited, the battery is protected through a battery protection strategy. By the method, when the intelligent battery identifies that the intelligent battery is short-circuited, the intelligent battery can execute a related protection strategy without operation or permission of a user, so that dangerous conditions such as spontaneous combustion of the battery are avoided, and the use safety of the battery is improved.

In some embodiments, when the method is used for other electronic equipment communicating with the intelligent battery, whether the battery is short-circuited or not can be accurately and quickly identified on line, when the battery is short-circuited, the battery is protected through a battery protection strategy, the working state of the electronic equipment is adjusted, the electronic equipment is also in a safe working state, and the use risk caused by the short-circuit of the battery is further avoided. For example, when the charger/charge manager charges/discharges the battery, if the short circuit of the battery is identified, the control reduces or stops the charging/discharging, and the safety of the battery is improved. When the battery supplies power to the movable platform, if the movable platform identifies that the battery is short-circuited, the discharging current of the battery is controlled to be reduced, and/or corresponding prompt is performed, so that the safety of the battery is improved. In particular, the discharge current of the battery can be reduced by limiting the operation of the movable platform, for example: adjusting the rotating speed of the motor, limiting a shooting device carried by the movable platform to shoot and the like.

The battery control method provided by each embodiment can accurately and quickly identify whether the battery is short-circuited on line, and realize the protection of the battery through the battery protection strategy when the battery is short-circuited, so that the use safety of the battery is improved.

When the existing battery, such as a lithium ion battery, is used, internal short circuit conditions, such as micro short circuit, often occur, and the short circuit can cause the battery to fail and catch fire and other accidents. The detection is difficult due to the occurrence of the internal short circuit of the battery, which is accidental. The short circuit may occur in different operating states of the battery, so that the detection of the short circuit of the battery is more difficult, and meanwhile, the problem that effective protection cannot be performed after the short circuit is detected exists.

Referring to fig. 7, fig. 7 is a schematic flowchart illustrating steps of another battery control method according to an embodiment of the present disclosure. The battery control method is applied to the intelligent battery, can more accurately identify whether the battery is short-circuited on line, and can effectively protect the battery.

As shown in fig. 7, the battery control method includes steps S201 to S205.

S201, acquiring the working state of the battery;

s202, determining target parameters according to the working state, and acquiring the target parameters of the battery as battery parameters of the battery;

s203, determining whether the battery is short-circuited according to the battery parameters;

s204, if the battery is short-circuited, determining a battery protection strategy corresponding to the short circuit of the battery in the multi-stage battery protection strategies according to the multi-stage battery protection strategies;

and S205, controlling the battery to execute the battery protection strategy.

The working state of the battery comprises a charging state and a discharging state, the target parameter is one or more battery parameters related to the working state, namely different working states need to use different battery parameters to identify whether the battery is short-circuited or not.

Specifically, the states of a charge switch and a discharge switch in the battery circuit may be detected, and the operating state of the battery may be determined according to the states of the charge switch and the discharge switch.

For example, the charging switch is turned on to determine that the working state of the battery is a charging state; the discharging switch is turned on, and the working state of the battery is determined to be a discharging state; the charging switch is turned off and the discharging switch is turned off, and the working state of the battery is determined to be the non-use state.

It should be noted that the micro control unit may detect and determine the operating state of the battery, or the related circuit may send a signal that may represent the operating state of the battery to the micro control unit, so that the micro control unit determines the operating state of the battery.

Specifically, after the working state of the battery is obtained, the target parameter is determined according to the working state of the battery, and the target parameter of the battery is obtained as the battery parameter of the battery.

Illustratively, if the working state of the battery is a charging state, determining constant voltage charging time and/or constant voltage charging capacity as target parameters according to the charging state; or if the working state is a discharging state, determining the ratio of the charge-discharge capacity as a target parameter according to the discharging state.

For example, when the battery is in a charging state, a constant voltage charging time as a target parameter is obtained for determining whether the battery is short-circuited; for another example, when the battery is in a discharge state, a charge-discharge capacity ratio as a target parameter is obtained for determining whether the battery is short-circuited.

And after the short circuit of the battery is determined, determining a battery protection strategy corresponding to the short circuit of the battery, and controlling the battery to execute the determined battery protection strategy. Wherein the battery protection strategy comprises at least one of the following: and discharging the battery to a preset voltage range corresponding to the safe storage of the battery, and controlling the battery to be in a locking state.

For batteries mounted on a movable platform, the temperature of the battery may be high due to a short circuit of the battery. And in some situations, such as aircraft flight, there is no discharge or lock-up protection for the battery. Therefore, the battery can be used at an over-temperature, the flight safety of the aircraft cannot be guaranteed when the battery is used at the over-temperature, the use safety of the battery cannot be guaranteed, and safety accidents are easy to happen.

Therefore, the battery protection strategy comprises a preset multi-stage temperature protection strategy, the preset multi-stage battery protection strategy corresponds to the preset multi-stage battery temperature range and is used for controlling the battery to execute the battery protection strategy corresponding to the current battery temperature so as to control the operation of the movable platform.

Specifically, after the short circuit of the battery is determined, the current battery temperature of the battery is obtained; determining a battery protection strategy corresponding to the current battery temperature according to the current battery temperature and a preset multi-stage battery protection strategy; and controlling the movable platform to execute the determined battery protection strategy. The safety of the movable platform and the battery can be improved by controlling the battery to execute a battery protection strategy corresponding to the current battery temperature.

Wherein the first battery temperature range is included below the normal use temperature threshold, the second battery temperature range is included between the normal use temperature threshold and the limited use temperature threshold, the third battery temperature range is included between the limited use temperature threshold and the first influenced lifetime temperature threshold, and the fourth battery temperature range is included above the second influenced lifetime temperature threshold.

The preset multi-level battery protection strategy refers to a preset multi-level strategy for protecting the safety of the battery. The preset multi-level battery protection strategy corresponds to a plurality of levels of temperature ranges of the battery and is used for controlling the battery to execute the battery protection strategy corresponding to the current battery temperature so as to control the operation of the movable platform.

The preset-level battery protection strategy may include one strategy or more than two strategies; a preset level of battery protection policy may include battery related (i.e., battery-side) policies, mobile platform related (i.e., mobile platform-side) policies, and user related (i.e., user-side) policies.

In one embodiment, the preset multi-stage battery protection strategy includes at least one of the following: the method comprises the steps of controlling a battery to continuously and normally operate, reducing discharge current of the battery, sending an instruction for indicating a movable platform to prepare for return voyage before stopping operation, sending a prompt for suggesting return voyage of battery over-temperature use to a user, sending an instruction for controlling the movable platform to warn the user of return voyage, sending an instruction for suggesting return voyage as soon as battery temperature is serious to the user, recording current discharge temperature of the battery, and locking the battery.

In one application, the plurality of levels of battery temperature ranges include at least one of: the temperature sensor is used for detecting the temperature of the working fluid, and is characterized in that the temperature sensor is below a normal use temperature threshold, between the normal use temperature threshold and a limited use temperature threshold, between the limited use temperature threshold and a first life-affecting temperature threshold, and above a second life-affecting temperature threshold. In some embodiments, the controlling the movable platform to execute the determined battery protection policy specifically includes: and if the current battery temperature is below the normal use temperature threshold, controlling the movable platform to continue normal operation.

For example, the mobile platform is controlled to execute the determined battery protection strategy, specifically: and if the current battery temperature is between the normal use temperature threshold and the limited use temperature threshold, reducing the discharge current of the battery and controlling the movable platform to operate restrictively.

Wherein, control movable platform and carry out the restrictive operation, specifically include: and reducing the discharge current of the battery and controlling the aircraft to limit the flight attitude.

Exemplary, restricted flight attitude, includes: controlling the aircraft to limit variable speed flight; alternatively, the aircraft is controlled to limit the altitude of flight.

For example, as shown in fig. 8, the flying height of the aircraft is lowered from H1 to H2, and the flying speed of the aircraft is reduced from V1 to V2, and the speed V1 is greater than V2, thereby ensuring the flight safety of the aircraft.

In some embodiments, the controlling the movable platform to execute the determined battery protection policy specifically includes: and if the current battery temperature is between the limited use temperature threshold and the first life-affecting temperature threshold, controlling the movable platform to execute a first preparation strategy before the movable platform stops running, wherein the first preparation strategy is used for preparing for return voyage before the movable platform stops running.

Specifically, if the movable platform stops operating and the discharging temperature recorded by the battery is above the second life-affecting temperature threshold, the battery is discharged to a safe storage voltage for storage and/or the battery is locked, so that the battery is prohibited from supplying power to the movable platform again.

In an embodiment of the present application, the normal use temperature threshold comprises 65 deg.C, the limited use temperature threshold comprises 75 deg.C, the first life affecting temperature threshold comprises 85 deg.C, and the second life affecting temperature threshold comprises 90 deg.C.

Referring to fig. 9, fig. 9 is a schematic flowchart illustrating steps of another battery control method according to an embodiment of the present disclosure. The battery control method is applied to the intelligent battery.

As shown in fig. 9, the battery control method includes steps S301 to S305.

S301, acquiring battery parameters of the battery;

s302, determining whether the battery is short-circuited according to the battery parameters;

s303, if the battery is short-circuited, determining the short-circuit degree of the short circuit according to the battery parameters;

s304, determining a battery protection strategy corresponding to the short circuit of the battery according to the short circuit degree and the multi-stage battery protection strategy;

and S305, controlling the battery to execute the determined battery protection strategy.

The multi-stage battery protection strategy comprises a plurality of battery protection strategies corresponding to different short circuit degrees, and the protection modes corresponding to the battery protection strategies are different.

Specifically, the short circuit degree corresponding to the short circuit of the battery may be determined first; and determining a battery protection strategy in the multi-stage battery protection strategies corresponding to the short circuit according to the short circuit degree.

Therefore, the battery can be controlled to execute the second-stage battery protection strategy, namely, the battery is controlled to enter a self-discharge program to discharge the battery, and/or prompt information for prompting a user that the battery is not available is output.

Because the battery is installed in the movable platform, the movable platform is provided with power. However, due to various use scenes, the movable platform may be dropped, bumped and the like, and accordingly, the battery is also dropped, bumped and the like. In case of falling, collision and other situations of the battery, when extrusion, short circuit or needling often occurs (such as the battery is installed in a movable device and is strongly extruded due to falling, collision and the like of the movable device), an internal diaphragm is broken to cause short circuit of a positive electrode and a negative electrode of a battery core, a large amount of heat is generated in the battery core within a short time, the heat is limited by a battery structure, the heat cannot be rapidly diffused to the outside of the battery, the temperature of the battery is too high, decomposition and combustion of active substances and electrolyte are caused, thermal runaway is caused, and the temperature of the battery rises explosively to cause combustion or explosion. Once such batteries are used, they pose a great safety hazard to users using the batteries, thus threatening personal and property safety, and once a problem of combustion or explosion occurs, the batteries are burnt out, making it difficult to investigate and analyze.

For such problems, the conventional processing method usually judges whether the battery is over-dropped or bumped by performing appearance inspection on the battery, or suggests a user not to drop or bump the battery and not to use the over-dropped or bumped battery through a battery case problem prompt or a specification prompt, so that the potential safety hazard cannot be avoided.

Therefore, the accidents such as falling and impact of the movable platform are one of the causes of short circuit of the battery, and therefore the battery control method provided by the embodiment of the application can protect the battery after the short circuit of the battery is determined and also needs to protect the battery before the short circuit of the battery occurs.

Specifically, acquiring a battery parameter of the battery, and acquiring an acceleration value of the battery before determining whether the battery is short-circuited according to the battery parameter; determining whether the battery falls or impacts according to the acquired acceleration value; if the battery is determined to be dropped or bumped, executing a safety strategy on the battery, wherein the safety strategy comprises at least one of the following: recording abnormal information, performing abnormal prompt, limiting charge and discharge of the battery, and controlling self-discharge of the battery.

The battery comprises a micro control unit, and the acceleration value of the battery is acquired by the micro control unit. Specifically, the acceleration value of the battery may be detected by a sensing circuit provided in the battery, transmitted to the micro control unit; the acceleration value of the movable platform may also be acquired by the micro control unit as the acceleration value of the battery. The battery is a smart battery, and the smart battery will be described as an example.

By acquiring the acceleration value of the intelligent battery and determining whether the intelligent battery falls or collides, whether the potential safety hazard exists in the intelligent battery 1 can be detected in real time and reliably, and a safety strategy is executed on the intelligent battery when the potential safety hazard exists in the intelligent battery, so that the use safety of the battery can be improved, and the occurrence of safety accidents is reduced.

The obtained acceleration value is at least the acceleration value in the gravity direction, and the obtained acceleration value can be used for determining whether the intelligent battery falls or not according to the acceleration value in the gravity direction. When the movable platform falls or impacts, the intelligent battery carried by the movable platform also correspondingly falls/impacts, and then the movable platform is determined to fall/impact. Therefore, the judgment basis can be provided as the responsibility determination problem caused by the movable platform fryer, and the judgment of whether the fryer is caused by the falling/collision of the movable platform or the fryer caused by the abnormal output power of the battery or the battery circuit and the like caused by the movable platform fryer is facilitated.

Specifically, whether the acceleration value of the intelligent battery in the gravity direction continuously exceeds a preset threshold value within a preset time is determined, and if yes, the intelligent battery is determined to fall.

In addition, whether the change value of the acceleration value of the intelligent battery in any direction within the preset time exceeds a preset threshold value or not can be determined, and if yes, the intelligent battery is determined to be impacted.

The anomaly information may include information related to the impact event (such as the time of impact, etc.). Therefore, if a safety accident occurs later, the reason of the safety accident of the battery can be traced according to the abnormal information.

In some embodiments, when it is determined that the smart battery has crashed, a security policy is implemented on the smart battery, which may include making exception prompts. For example, an audible and/or visual safety prompt may be issued to alert the user when it is determined that the smart battery has been bumped.

Accordingly, the smart battery may also include audible and/or visual means (e.g., a speaker and/or a display) to present audible and/or visual safety prompts to the user.

In some embodiments, when it is determined that the smart battery has a crash, a security policy is enforced on the smart battery, which may include limiting charge and discharge usage of the smart battery.

For example, limiting charge and discharge usage of the smart battery may include at least one of: the method comprises the following steps of limiting the charging and discharging times of the intelligent battery, limiting the charging and discharging time of the intelligent battery every time, and forbidding the charging and discharging of the intelligent battery. The safety of the battery can be fundamentally improved, and the occurrence of safety accidents is reduced.

In some embodiments, when it is determined that the smart battery has a crash, a security policy is executed on the smart battery, which may include controlling self-discharge of the smart battery.

Illustratively, controlling the self-discharge of the smart battery may issue at least one of: strengthening maintenance, keeping cleanness and keeping dryness. In this embodiment, the smart battery may also include audible and/or visual means (e.g., a speaker and/or a display) to present the prompt to the user.

Of course, in addition to whether the battery is bumped or dropped, the smart battery may record other information of the usage process, such as discharge current, battery temperature, and the like, so as to analyze and locate the cause of the short circuit after identifying the short circuit of the battery, determine the cause of the short circuit, such as the cause of the bumped or dropped mobile platform, or the cause inside the battery.

The battery control method provided by the embodiment can not only identify the occurrence of short circuit of the battery according to the battery parameters of the battery, but also further determine the short circuit degree according to the battery parameters, and then determine the corresponding battery protection strategy according to the short circuit degree and the multi-stage battery protection strategy, thereby realizing multi-stage protection of the battery. In addition, when the battery is possibly short-circuited, a corresponding safety strategy can be executed. Therefore, the battery is effectively protected, and the safety performance of the battery is improved.
