Description
Technical field
Present invention relates in general to a kind of Battery Diagnostic devices, and more particularly to one kind being assemblied in PHEV (charging type electrics
Motor-car) type motor vehicles on Battery Diagnostic device.
Background technology
Implement new iso standard within 2012.The standard has the new function secure reference system suitable for automobile industry
System.The standard is it is intended that reinforce the reliability of vehicle electronics instrument.For each function of in-vehicle electronic system, standard
ISO26262 defines multiple safety integrity levels (ASIL, i.e. Automotive Safety Integrity Levels (vapour
Vehicle safety integrity level)).It is marked as being able to verify that by equipment from A (least dangerous) to the these requirements grade of D (most dangerous)
Whether the system component of quotient and manufacturer's production meets the security target of function.In order to ensure these required safe classes, mark
The requirement of quasi- ISO26262 is applied to the different field in entire vehicle life cycle：Tissue areas, file
(documentaire) field and technical field.
In general, the motor vehicles (i.e. chargeable electric and hybrid vehicle) of PHEV types are mounted with battery and can
Implement the electrical architecture of the diagnosis to battery (preferably, 12V batteries).
In this traditional electrical architecture, vehicle includes diagnostic member, which is, for example, can be continuously real
Apply the diagnosis to 12V batteries vehicle battery charging assessment box (BECB), but the diagnostic member generally can not cover it is high
ASIL grades.However, the framework studied needs the battery for being disposed with higher level (ASIL B) in order to meet new standard
Diagnosis.
For example, in " tradition " electrical architecture and in typical architecture corresponding with " stop and start " operation, it is recognized that, electricity
The ASIL grades that pond provides are ASIL B grades and Battery Diagnostic system is enough, this is because following components/life rank
Section allows the realization of the target.
In fact, in the Dai-ichi Mutual Life Insurance stage of battery, power test can be implemented by starting the excitation generated by first time,
The power test provides the good instruction of cell health state.The situation is confirmed in conventional architectures.Then, second
In life stage, battery energization is kept relatively low during operation, and alternating current generator provides the major part in energy, and described
Battery provides power to the relatively short actuator of run time (DAE, ESP etc.).This situation is also demonstrate,proved in conventional architectures
It is real.Finally, in the third life stage, i.e., when car speed is less than 25km/h, the supply loss of safety member is battery institute
The ASIL B grades being in.
Battery monitoring device (BECB) for good and all counting cell charging state, and thus indicate that for second and third life
Stage enough health status information.On the contrary, in new PHEV vehicles, occur from now on, one or more explained above
Life stage is no longer realized.For example, in PHEV vehicles, above-mentioned Dai-ichi Mutual Life Insurance stage and third life stage are not demonstrate,proved
It is real, this is because there is no can be more than 20km/h to the first request of starter and speed.
In view of above- mentioned information, in order to ensure required ASIL B grades, it is therefore desirable to find a kind of diagnosis that is used for newly and fill
It is loaded in the deagnostic package of the battery in PHEV vehicles.Different deagnostic packages is developed.
For example, file DE102014004791 is described uses DC/DC in PHEV electrical architectures, to implement to vehicle-mounted
The diagnosis being connect between network and battery.For this purpose, DC/DC generates the modulated signal between 50Hz and 200Hz, then
Device calculates the resistance between the both ends of battery and determines quality of connection.However, the device of the type can not be such as new standard institute
It is required that ground improves ASIL grades.
