The ingredient of electrochemical reaction gas in analysis battery is crossed to judge whether it is in the situation that temperature steeply rises.For another example, the electricity
Pond parameter can also be the parameter that can characterize cell pressure exception, whether because temperature rises gas occur to analyze in battery
Pressure brought by excessively expanding rises problem.For another example, which can also be the parameter that can characterize battery collision, such as logical
The signal parameter that air bag when vehicle meets with collision is triggered and generates is crossed, to analyze whether battery occurs because of collision
Burning or explosion issues.Certainly, very mature in the prior art for obtaining the detection part of aforementioned parameters, therefore these
The acquisition of parameter has enough hardware supporteds, not reinflated herein to repeat.
In addition, also the abnormal Rule of judgment of power battery can be limited to elder generation to further increase the accuracy of the judgement
Meet afterwards: battery temperature is more than that pre-set battery discharges critical value;And the bus communication of power battery is abnormal.This is because
When battery temperature is increased to that there are the battery management system that in the case where fire risk, may lead on starting power battery is externally defeated
The communication abnormality of signal out.Therefore, if power occurs suddenly after battery temperature is more than pre-set battery release critical value
Battery bus communication abnormality and when situation no longer with follow-up signal, also can determine whether to exist for power battery abnormal, and pole can
Phenomenon on fire can occur.
Specifically, the battery abnormality processing mode in step S300 in previous embodiment can include: discharge vehicle
Power battery.At this point, in confirmation power cell of vehicle there are after exception, by discharging power battery, thus relieve vehicle with
Connection between power battery can effectively avoid the unstable shapes such as burning or the explosion that power battery then causes because abnormal
Condition.Releasing movement can be carried out by issuing control signal to corresponding battery locking system, can hereafter be directed to the battery lock
Locking apparatus makes exemplary illustration.
Wherein, the operation of the power battery of the release vehicle can be by Far end control signal or vehicle end control signal triggering.Make
It distally may include vehicle maintenance end, such as the server end that service companies are constructed for a variety of achievable specific examples;Distally
It may also include the end app etc. installed on user terminal, such as individual mobile terminal;And vehicle end may include vehicle central control system etc..
During triggering the operation of power battery of vehicle, it can cover: control vehicle automatically releasable battery;Or still it is being unfamiliar with
Manual releasing battery is used when auto control system in vehicles or thrashing;Or still it is being unfamiliar with auto control system in vehicles,
Also be unfamiliar with disassembling section or user not onboard or near vehicle when, can be controlled by authorizing in vehicle release battery
It is one or more.Wherein, as one group of example, should " authorization control vehicle discharges battery " mode include: vehicle user end to
Vehicle maintenance end provides authorization, and discharges battery by vehicle maintenance end control vehicle, is applicable to user not near vehicle
Situation;Or vehicle maintenance end provides authorization to vehicle user end, and discharges battery by vehicle user end control vehicle, can fit
Purchase situation of the vehicle without operating vehicle control system recently for user.In addition, as another group of example, it should " control vehicle
The mode of automatically releasable battery " includes: automatically releasable battery after receiving and releasing order, and belongs to conventional release battery behaviour
Make mode.Alternatively, automatically releasable battery belongs in Vehicular battery after not receiving and releasing order within the particular preset period
Temperature anomaly does not cause user terminal or safeguards that system of end when paying attention to is saved oneself one of mode, and vehicle safety can be further improved,
Improve its reliability.
More specifically, the battery abnormality processing mode in the step S300 in aforementioned any embodiment or combinations thereof may be used also
It include: to issue the alarm signal of power battery exception before discharging the power battery, thus further improve the controlling party
Method.For example, the alarm signal can to one in vehicle central control system, vehicle user end, vehicle maintenance end and vehicle company or
Multiple sendings.This alarm signal will further cause related personnel's note that so as to execute release battery or treatment of battery release
The contingency question at the scene of putting, avoids fire from magnifying.
More specifically, the step S300 in aforementioned any embodiment or combinations thereof may also include that in step S300, open
Dynamic reserve battery makes its work, so that vehicle sails out of.Thus vehicle or user will be avoided to be caused explosion because on fire by battery
Phenomena such as influence, this can further improve the safety of vehicle.
In addition, it is contemplated that in electric vehicle battery operation complexity, by simply setting up a temperature value or one
Temperature range is being a kind of not accurate enough judgment method whether dividing cell safety.In fact, it is more reasonable and be accurately,
Multiple parallel judgment criterias are set.
Wherein, there may be preconditions for part judgment criteria, for example, in s 200, if vehicle it is in operating status this
When in one precondition, in the state of being generally in electric discharge due to battery at this time to provide power for vehicle, can base
It is arranged in experiment test value or daily use monitor value etc. or updates battery discharge temperature preset range, and judges the battery
It is abnormal whether real time temperature exists relative to the battery discharge temperature preset range, for example, whether S2001a, determine battery temperature
Higher than first threshold.Wherein, it is appreciated that, the operating status of vehicle can be regarded as vehicle and be in starting state, traveling shape
State or on-position etc..Hereafter, S2003a is executed, in the case where determining that battery temperature is higher than first threshold, is cut off described dynamic
Power battery, and reserve battery is activated to make its work;And S2005a, monitor the temperature of powered cell and in the power battery
Battery temperature be more than the battery release critical value when enter step S300.Abovementioned steps are intended to abnormal to battery temperature
Phenomenon, which is made, to be remedied, and is determined to its inducement, analyses whether it is that battery temperature is abnormal caused by current operation is improper.If
Such factor is excluded, then maximum probability being determined to, temperature anomaly occurs because of unknown cause for battery, and most probably thus induce
Fire.For example, illustrating that temperature anomaly before this may be due in battery operation if its battery stops heating after being switched
Improper operation causes, and can also restore.And if it continues to heat up, and illustrates that the temperature anomaly of the battery has been difficult to stop, subsequent pole
The problems such as on fire may occur, then should start to execute remedial measure.
For another example, in s 200, if vehicle is in this precondition of charged state, since battery at this time is usually located
In charging in the state of outwardly drawing energy, therefore, can based on test test value or daily use monitor value etc. come
Setting updates battery charge temperature preset range, and judges whether the battery real time temperature is pre- relative to the battery charge temperature
If there is exception in range, for example, S2001b, determines whether battery temperature is higher than second threshold.Hereafter, S2003b is executed, true
Battery temperature is determined higher than in the case where second threshold, if multi gear charge mode is not present in battery, is controlled battery and is stopped receiving electricity
Power, if battery remove selection control battery and stop receiving outside electric power there are multi gear charge mode, also may be selected to make its from
Fast charge mode switches to slow charging mode.It is appreciated that the various it is described herein it is quick be charged as relativity at a slow speed
Concept, and both nonessential restrictions are should be at respectively in certain specific charge voltage range.S2005a is then executed, described in monitoring
Temperature of powered cell simultaneously enters step S300 when the battery temperature of the power battery is more than battery release critical value.
Abovementioned steps are equally directed to make the phenomenon of battery temperature exception and remedy, and are determined to its inducement, analyse whether due to
Improper operation in battery charging and cause battery temperature abnormal.If excluding such factor, maximum probability is determined to battery
Temperature anomaly occurs because of unknown cause, and most probably thus induces fire.For example, if its battery disconnects or is changing charging mould
Stop heating after formula, then illustrates that temperature anomaly before this may be caused due to the improper operation in battery charging, can also restore.And
If it continues to heat up, illustrates that the temperature anomaly of the battery has been difficult to stop, the problems such as on fire then can most probably occur, then answer
When start execute remedial measure.
In aforementioned two kinds of situations, first threshold and second threshold have been continued to use respectively and has been done to be compared with battery temperature
Out whether Yi Chang judgement, this is because battery may usually have different normal temperature sections in different situations, therefore
It is also different for the set condition of abnormal judgement.Certainly, this is exemplary rather than exclusive, it is also possible to which there are first
Threshold value it is equal with second threshold or overlapping situation.
In addition, another part judgment criteria is it may even go so far that directly execute.This is because may go out in practical application
Existing vehicle causes on fire by the abnormal situation such as extraneous physical impact, puncture, collision, immersion suddenly.For such burst
Phenomenon on fire can carry out early warning by being directly battery setting cell safety temperature preset range.At this point, no matter vehicle is in
Under which kind of state, it is abnormal will directly to judge whether battery real time temperature exists relative to cell safety temperature preset range.
