All the above alternatives, can form the alternative embodiment of the disclosure according to any combination, and the disclosure is real It applies example and this is no longer repeated one by one.

Fig. 2A is according to a kind of flow chart of battery method for early warning shown in the embodiment of the present disclosure, battery surface cladding pressure Conductive film material, the piezoelectric film material are divided into multiple material blocks, each material block and battery in multiple material block Prior-warning device individually connects, below the embodiment of the present disclosure will carry out expansion explanation to embodiment shown in FIG. 1.As shown in Figure 2 A, This approach includes the following steps.

In step 201, target electric signal is obtained, target electric signal refers to be become in the specified parameter of target material block The electric signal generated when change, specified parameter include deformation quantity or temperature, and target material block is any in multiple material block Material block.

Wherein, the deformation that the deformation quantity of the target material block is used to occur when indicating target material block by external force Size, the target electric signal are the voltage difference at target material block both ends when the specified parameter of target material block changes.

It should be noted that the piezoelectric film material is a kind of crystalline material with piezoelectricity and pyroelectricity, such as PVDF (Polyvinylidene Fluoride, polyvinyladine floride).The piezoelectric film material by external force deformation occurs when, Negative ions can generate relative displacement in each structure cell of crystal, be overlapped positive and negative charge center no longer, lead to crystal Polarization, thus piezoelectric film material by external force deformation occurs when both ends of the surface will appear heterocharge so that the piezoelectric membrane Voltage difference is generated between the both ends of material, after removing external force, piezoelectric film material can be restored to uncharged state again；Instead It, when piezoelectric film material polarizes in the electric field, the relative displacement at positive and negative charge center will lead to material deformation, here it is The piezoelectric effect of piezoelectric film material with piezoelectricity.Wherein, structure cell is the most basic geometric units for constituting crystal.

In addition, the polarization of piezoelectric film material can vary with temperature and change, near two surfaces of piezoelectric film material Respectively there is one layer of bound charge, these bound charges are shielded by the free charge of equivalent opposite-sign in thermal equilibrium state, pressure Conductive film material does not show that electrically, polarization changes when the temperature of piezoelectric film material changes, free charge to the external world Bound charge can not be shielded completely, cause piezoelectric film material surface that the release and absorption of charge occurs, so that the piezoelectric membrane Voltage difference is generated between the both ends of material.

It is possible to further after obtaining target electric signal, by the voltage difference at target material block both ends and target position Instruction information is stored into the corresponding relationship between voltage difference and position indication information.Wherein, instruction information in target position is used for Indicate cladding region of the target material block on the battery.

It should be noted that cladding region of each material block on the battery can be numbered according to rule, lead to It crosses and numbers to indicate cladding region of each material block on battery, it can also be using other modes come table in certain practical application Show cladding region of each material block on the battery, it such as can be using the coordinate of each material block center as the material block Coordinate, cladding region of each material block on battery is indicated with coordinate information.In this regard, the embodiment of the present disclosure not limits It is fixed.The following embodiment of the present disclosure is described in detail by taking the form using number as an example.

For example, as shown in table 1, it is assumed that voltage difference indicated by the target electric signal got is " U1 ", it is assumed that target material Expect that cladding region of the block on the battery is " region 1 ", by the corresponding position indication information of voltage difference " U1 " " region 1 " store to In table 1, so as to obtain the corresponding relationship between deformation quantity as shown in Table 1 and position indication information.

Table 1

Voltage difference	Position indication information
		U1	Region 1

It should be noted that the embodiment of the present disclosure is only with shown in above-mentioned table 1 between voltage difference and position indication information It is illustrated for corresponding relationship, above-mentioned table 1 does not constitute the embodiment of the present disclosure and limits.

In step 202, it is based on target electric signal, determines the variable quantity of the specified parameter of target material block.

It, can be based on target electric signal from presetting wherein it is determined that when the variable quantity of the specified parameter of target material block Specified parameter curve fit in determine target material block specified parameter variable quantity, the specified parameter curve fit is for referring to Show the relationship between specified parameter and variable quantity.The specified parameter curve fit can be the first matched curve, or the Two matched curves, first matched curve are used to indicate the relationship between electric signal and deformation quantity, which is used for Indicate the relationship between electric signal and temperature variation.

Since the specified parameter of target material block includes deformation quantity or temperature, mesh is determined based on target electric signal When marking the variable quantity of the specified parameter of material block, need first to determine the producing cause of target electric signal, since deformation is for the pressure The influence of conductive film material is much larger than influence of the temperature to the piezoelectric film material, therefore it is poor to can be set a predeterminated voltage, When the voltage difference indicated by the target electric signal reaches the predeterminated voltage difference, determine that target electric signal is due to target material block Deformation quantity changes the electric signal of generation, when the voltage difference indicated by the target electric signal is not up to predeterminated voltage difference, determines Target electric signal is the electric signal of generation of being changed due to the temperature of target material block.

In practical application, due in the short period due to deformation quantity change the electric signal of generation instantaneous amplitude variation Greatly, and whithin a period of time change frequency is very fast, and since the instantaneous amplitude variation of the electric signal of temperature change generation is small, and Change frequency whithin a period of time is slower, accordingly it is also possible to by change frequency of the target electric signal in preset duration with And amplitude of variation determines that target electric signal is the electric signal due to deformation quantity changes or temperature changes generation.When It can also so determine by other means, this embodiment of the present disclosure is not limited.

When determine target electric signal be changed due to the deformation quantity of target material block generation electric signal when, according to mesh Mark the deformation quantity that electric signal determines target material block from the first matched curve.When determining that target electric signal is due to target material The temperature of block change generation electric signal when, target material block is determined from the second matched curve according to target electric signal Temperature variation.

It should be noted that voltage difference indicated by target electric signal is bigger, the pressure that target material block is born is bigger, And then the deformation generated is bigger, that is to say, the deformation quantity of target material block is bigger.Correspondingly, indicated by target electric signal Voltage difference it is bigger, the temperature change of target material block is more obvious, and the temperature variation of generation is also bigger.

In addition, first matched curve can be fitted to obtain in advance with the second matched curve, it, can be preparatory in practical application Multiple groups electric signal and corresponding deformation quantity are measured, is fitted according to this multi-group data, obtains to indicate electric signal and shape First matched curve of the relationship between variable.Similarly, multiple groups electric signal and corresponding temperature change can also be measured in advance Amount, is fitted according to multi-group data, obtains to indicate the second matched curve of the relationship between electric signal and deformation quantity.

For example, as shown in Figure 2 B, using O as coordinate origin, using horizontal axis as electric signal namely voltage difference U, using the longitudinal axis as deformation Measure F.Assuming that measuring multi-group data is respectively (U1, F1), (U2, F2) ... (Un, Fn), wherein n >=2, it is assumed that according to this multiple groups number Curve F=f (U) as shown in Figure 2 B is obtained according to fitting.

It further, can be with after the variable quantity of specified parameter for determining target material block based on target electric signal The variable quantity of the specified parameter of target material block and target position instruction information are stored to Parameters variation amount and position instruction and believed In corresponding relationship between breath.

Since specified parameter includes deformation quantity or temperature, pair between Parameters variation amount and position indication information It should be related to or corresponding relationship between deformation quantity and position indication information or temperature variation and position indication information Between corresponding relationship.

For example, as shown in table 2, it is assumed that the deformation quantity obtained after obtaining target electric signal is " F1 ", it is assumed that target material Expect that cladding region of the block on the battery is " region 2 ", by the corresponding position indication information of deformation quantity " F1 " " region 2 " store to In table 2, so as to obtain the corresponding relationship between deformation quantity as shown in Table 2 and position indication information.

Table 2

It should be noted that the embodiment of the present disclosure is only with shown in above-mentioned table 2 between deformation quantity and position indication information It is illustrated for corresponding relationship, above-mentioned table 2 does not constitute the embodiment of the present disclosure and limits.

For example, as shown in table 3, it is assumed that the temperature variation obtained after obtaining target electric signal is " T1 ", it is assumed that mesh Marking cladding region of the material block on the battery is " region 3 ", by the corresponding position indication information " region of temperature variation " T1 " 3 " store into table 3, so as to obtain the corresponding pass between temperature variation and position indication information as shown in table 3 below System.

Table 3

Temperature variation	Position indication information
		T1	Region 3

It should be noted that the embodiment of the present disclosure only with temperature variation shown in above-mentioned table 3 and position indication information it Between corresponding relationship for be illustrated, above-mentioned table 3 not to the embodiment of the present disclosure constitute limit.

In step 203, the variable quantity of the specified parameter based on target material block carries out early warning.

In actual implementation, it can be carried out pre- when the variable quantity of the specified parameter of target material block reaches default variable quantity It is alert.It that is to say, when the deformation quantity of target material block reaches default deformation quantity, carry out early warning；Or the temperature when target material block When degree variable quantity reaches preset temperature variable quantity, early warning is carried out.

, may be when the variable quantity of the specified parameter of target material block reach default variable quantity in practical application, battery is Through impaired, and it is in than relatively hazardous state, at this point, may just carry out early warning to battery will occur accident, such case Early warning without too big effect, then in order to more effectively to defective cell carry out early warning, can be in target material block When the variable quantity of specified parameter not up to presets variable quantity, it that is to say that the variable quantity of the specified parameter of target material block is close default When variable quantity, early warning is carried out.It realizes that process can be with are as follows: presets the variable quantity difference of specified parameter, the variable quantity difference It can be deformation quantity difference or temperature variation difference, when default variable quantity subtracts the variation of the specified parameter of target material block When the difference measured is less than or equal to the variable quantity difference, it can determine that the variable quantity of the specified parameter of target material block connects Closely default variable quantity more effectively carries out early warning to defective cell to realize at this point it is possible to carry out early warning.

It should be noted that the variable quantity difference of the specified parameter is smaller, and target material is subtracted when working as default variable quantity When the difference that the variable quantity of the specified parameter of block obtains is less than or equal to the variable quantity difference, show battery at this time also not by Damage, but if heat waste may be occurred by continuing to use, causes certain danger.

In actual conditions, deformation quantity difference can be preset, when the deformation quantity of default deformation quantity and target material block it Between difference when being less than or equal to the deformation quantity difference, can determine the deformation quantity of the target material block close to default deformation quantity but Not up to default deformation quantity, can carry out early warning at this time；Or temperature variation difference can be preset, when preset temperature becomes When difference between change amount and the temperature variation of target material block is less than or equal to temperature variation difference, the mesh can be determined The temperature variation of material block is marked close to preset temperature variable quantity but not up to preset temperature variable quantity, can be carried out at this time pre- It is alert.

Certainly, in practical application, the variable quantity of the specified parameter according to target material block can also be carried out by other means Early warning is carried out, for example, can carry out according to the amplitude of variation of the variable quantity of the specified parameter of target material block and variation tendency Early warning, that is, a default amplitude can be preset, when the variable quantity of the specified parameter of target material block and the last time of record Specified parameter variable quantity compared to being that the amplitude for increasing, and increasing reaches the default amplitude, early warning can be carried out at this time.Its In, when the amplitude that the variable quantity of the specified parameter of target material block increases reaches the default amplitude, indicate that the battery is in danger Dangerous state will cause personal injury and property damage if continuing to use.For the variation according to the specified parameter of target material block Amount carries out the mode of early warning, and the embodiment of the present disclosure not limits.

It should be noted that the mode that the variable quantity of the specified parameter based on target material block carries out early warning includes that triggering should At least one of in mobile terminal vibration, jingle bell, flashing sign, sending phonetic order where battery.For example, can be in mesh When the deformation quantity of mark material block reaches default deformation quantity, the vibration device of battery prior-warning device control mobile terminal starts to shake, To remind user's battery it is possible that problem；For example, when the deformation quantity of target material block reaches default deformation quantity, the battery Prior-warning device controls signal lamp flashing；Or battery prior-warning device triggering microphone device issues phonetic order.Certainly it actually answers Early warning, such as when the deformation quantity of target material block reaches default deformation quantity, the electricity can also be carried out using other modes in Pond prior-warning device can trigger quiet electricity generating device and generate electrostatic, and the electrostatic that wherein the electrostatic generator generates will not make human body At injury, without limitation to this embodiment of the present disclosure.

In actual conditions, carried out through the above way according to the deformation quantity of target material block or temperature variation pre- It is alert, it realizes before serious problems occur, it is pre- effective defective cell can be carried out according to the stress or temperature of battery surface It is alert, to remind user, avoid bringing personal injury and property loss to user due to battery problems.

It should be noted that since piezoelectric film material is divided into multiple material blocks, each material by the embodiment of the present disclosure When the specified parameter of block changes, an electric signal can be all generated, moreover, when deformation occurs or temperature for the piezoelectric film material Degree variation when, in the same time, there may be the specified parameters of at least one material block to change, and that is to say, can generate to A few target electric signal can realize early warning according to above-mentioned steps 201- step 203, with reality for each material block Battery early warning is now carried out according to the deformation quantity of any material block in multiple material blocks or temperature variation.

In practical application, early warning is carried out to battery, may remind the user that and do not use the defective cell, but user may Electricity still can be being eventually led to so that battery works on using mobile terminal because a variety of causes has ignored the warning information Heat waste occurs for pond, phenomenon on fire occurs.After there is phenomenon on fire, which has not been available, and technical staff can be right The cell exhaust utilize, its extent of damage is analyzed according to the defective cell and judges its damage reason, so as to battery structure into Row improves, and improves the service life of battery, and to analyze the damage reason of the battery, that is to say reason of fire, needs first to determine The damaged location of the battery, i.e., region on fire.

In step 204, after early warning, when heat waste occurs for the battery, the region on fire on the battery is determined.

In practical application, the various problems such as warning information, contingency may be had ignored due to user may cause electricity Heat waste occurs for pond, in turn results in the serious problems of battery catches fire, and technical staff needs to analyze defective cell, and determining should The reason of fire of the degree of injury of defective cell and the defective cell, and the reason of fire that analyze the battery first will be true Fixed region on fire can be determined by the following two kinds mode in the cards when heat waste occurs for the battery in a practical situation Region on fire on the battery.
