Description
Technical field
The present invention relates to a kind of advance equipment, a kind of component, a kind of for determining the pre- of conductive part in operation
The device of the time point that anti-property is changed and method.The invention particularly relates to the preventive replacement demand of safety fuse
Indicate.
Background technology
The electrification of private individual character means of transportation develops rapidly at this stage.According to a kind of scheme, arrange in a motor vehicle high
Piezoelectric battery provides electric energy by the high-tension battery to electric drive as energy storage device.Here in case of a fault by storage
Energy device can produce very big electric current (such as 4500 peace or bigger).In order to ensure the electric security of vehicle-mounted drawing electric network, if
Safeties are put, the safeties will bear very big electric current under normal circumstances.The safeties are often with the insurance that fuses
The form of device is arranged in high-tension battery, and the high-tension battery must be designed with high design current/rated current.In order to
The overcurrent of of short duration permission can be born, safety fuse is even must be designed to for than being wished for fusing performance originally
Higher design current/rated current.As high dynamic load and design current/rated current separate electricity with required
Relatively small gap between stream, in the case of the distinctive boundary condition of consideration motor vehicle, whole operational phase is to correct
Safeties design propose high request.In other words, there is following goal conflict：Safeties should have as little as possible
Loss coefficient ground allows the overcurrent of of short duration permission, but in case of a fault in order to protect the vehicle-mounted drawing electric network again should the extremely short phase
Bigger electric current is forbidden on ground.Therefore, safeties are designed for certain application cases, are tested and with phase in the prior art
Little number of packages is produced.Safeties are conventionally selected to have higher than needed in the case of without ageing process originally
Rated current, to make ageing process not cause the operation risk of advance equipment.The parameter determination of safeties is based on aging
Estimate to carry out, aging the estimating assumes safeties upper limit in energy storage device conductive capability in entirely specific service life
Upper use.Alternatively, the replacing of safeties is carried out according to (passiveness) service intervals for determining are guarded.This does not consider actually to enter
Capable safeties stress/aging.
10 2,010 041 998A1 of document DE discloses a kind of for predicting the workability of relay or contactor
Method, here, determines aging or adhesion prevention by temperature curve.Contactor aging especially because switching process is drawn
Rise, the aging generation impact of part of the switching process according to switching frequency and switch electrical power intensity on guiding electric current.Accordingly
Ground is proposed, and switching process is counted or determines each switch power, for estimating the workability of part.
10 2,012 215 063A1 of document DE discloses a kind of contactor monitoring circuit, and wherein, aging counters pass through
Feedback link is in monitoring circuit.It is capable of identify that the quick aging of contactor in this way and can revises to monitored
Contactor ageing state overly conservative estimation.
Approach known in the prior art does not disclose the part such as safety fuse for persistently guiding electric current, needs
Unnecessary high becoming specifically was developed for application/target originally.Above-mentioned method for designing is in the ginseng of other integrated separation elements
Critical disconnection aspect of performance when number design (packaging and cost) and short circuit is unfavorable.Also make in terms of care and maintenance
This raising, because service intervals are determined according to the passiveness aging (high intensity use) of all parts, although end user
Concrete travel situations do not meet the use of such high intensity sometimes.
Content of the invention
Therefore, the task of the present invention is, eliminates drawbacks described above.
According to the present invention, above-mentioned appointed task by a kind of for determining the preventive replacement of conductive part all the time when
Between the method put solving.Thus the part does not especially have the switch that can be for example configured to relay or contactor.Additionally,
The scope of the invention of preventive replacement in to(for) part is interpreted as such process：Part continues although also having in this process
Feature but (for example being caused by aging) be replaced, to ensure to continue reliable function.Determine part in the first step
The continuous behaviour in service for determining over time." continuous " behaviour in service should be particularly understood that within the scope of the present invention, determined
Size of current and this unstable change preferably with the switching process for determining or recognizing part or electric operation characteristic parameter
Unrelated.Of course, it is possible to be determined determining continuous behaviour in service by carrying out adopting sampling formula to characteristic parameter in different time points.Change
Sentence is talked about, and need not especially carry out continuous behaviour in service determination.The determination but can be in part run duration when predetermined
Between point or just carry out when predetermined monitored characteristic parameter critical value is reached.Particularly, under portion's steady operational status not
Switching process or electrical feature parameter are counted or such process or parameter are processed respectively or integrated.Then should
Behaviour in service is compared with predetermined reference.As behaviour in service can affect ageing process, can read from memory
Distribute to the behaviour in service characteristic value and as predetermined reference with determined by behaviour in service be compared.Therefore may be used
To distribute a predetermined ageing state characteristic value to the reference.As long as determine between behaviour in service and reference the presence of predetermined closing
System, just exports a signal for representing preventive replacement time point.Especially can making to the equipment that marches forward comprising the part
User carries out the output.The signal can for example show that repair shop searches, and service intervals expire.Alternatively or additionally, should
Signal can produce fault memorizer registration, continue aging part also to replace in inspection from now on.As a result, molten
The design of disconnected safeties can more be directed to disconnection.In addition remaining part can be designed to less parameter surplus.Conversely,
By determine part reality aging and shows in time possibility needs part replacement, can avoid including the driving of the part
It is premature failure.
Appurtenance provides the preferred extension of invention.
Behaviour in service for example can be with the current loading of identification element.In other words, can determine over time and be drawn by part
The current strength led and total amount is drawn according to predetermined rule.The here rule defines part (disappearing based on current loading
Consumption) behaviour in service.The accordingly low temperature that can determine part or temperature corresponding with part temperatures to use it for identification old
Change state.Particularly, both investigate the electric energy that is directed and investigated temperature load and then largely can accurately reflect part
Actual ageing state.Can also determine that other are represented by the parameter of the electric energy of the part transfers.For example resistance can known
In the case of determine heating and the current loading of part using voltage measurement.The determination of behaviour in service can be in multiple cycles of operation
In addition carry out above and on the significantly greater length of time period.Particularly, the determination of behaviour in service is directly being constructed according to the present invention
Advance equipment put into operation first after start, and change part in other words by safeguarding people with output signal or with actual
Member is reset to the interval for determining behaviour in service and is terminated.Thus according to present invention determine that behaviour in service with predetermined
Mode, may be through some days and/or week and/or the moon with respect to the relation of reference and before the output of proposed signal
And/or year.
The reference for example can be preserved in the form of characteristic family, and this feature curve is represented and behaviour in service dependent part
Part ageing process.Particularly in characteristic family, ageing process can become quadratic relationship with the electric current guided by the part.It is preferred that
Can be to electric current or its integrated square, for determining the behaviour in service characteristic parameter being directly proportional to ageing state.Bent in feature
It is also contemplated that temperature in line race.Especially temperature can also produce the impact of quadratic relationship to the characteristic parameter of behaviour in service.
The part can be for example safeties (such as safety fuse), and the safeties are meeting the operation of regulation
Middle flow through by electric energy, to drive advance equipment, the electric energy for example brings the electric current in the range of up to 500 amperes and up to
10000 amperes of short circuit current.Alternatively or additionally, the part can be provided for protecting the vehicle-mounted of electrically driven (operated) advance equipment
Drawing electric network.The electric energy guided by these parts makes part relatively quickly aging, thus, output signal is responded according to the present invention
On the one hand cause height safety in operation to change part, on the other hand cause the design of vehicle-mounted drawing electric network component preferably to accord with
Close actual requirement.
The signal for example enters in other words in part can also be in the situation for not having to specially require in equipment normal operating condition
Lower output.In other words, signal be not in the state of fault is very likely to occur, facing or even have occurred and that
Output.But especially when the signal will not make location user substantially divert one's attention from the affairs of important or relation safety
Output signal.As described above, the signal may also lead to formulate fault memorizer registration, and the fault memorizer registration itself is not
It is directly to be recognized by user, but by the attendant that may be participated in just recognizing.
Thus, in the clear and definite scheme of the present invention propose, by operation in order to battery management system (BMS) other
Function and the measurement data (particularly electric current and temperature) collected are determining remaining service life prediction so that high-voltage insurance
Device can be changed in possible time point the latest in the maintenance scheme of vehicle, and do not occur unnecessary part to disconnect or
Failure.
The method for being proposed makes it possible to replace the (more favourable and less so as to quality) high of small parameter in general manner
Splenium part.The maintenance of the adaptation load that in this way realizes avoids the failure that client can experience, and do not produce unnecessary
Expense.
Can be using electric current and possible related temperature data, so as to by involved height for this battery management system
The consumption of splenium part determines the remaining life of the part using model.Accordingly, for the high-voltage fuse insurance that investigates here
Device, design current/rated current and temperature impact are whereby it may be said that by using specifically overall next for corresponding fusing
Application.If the remaining life that estimates is less than the value determined in the range of in maintenance scheme, it is required that end user goes maintenance
