Description of the drawings
The present invention is described in further detail below according to drawings and Examples.
Fig. 1 is the method block diagram of the BMS voltage acquisition fault handling methods described in embodiment one.
Specific embodiment
Technical scheme is further illustrated below in conjunction with the accompanying drawings and by specific embodiment.
Embodiment one
The present embodiment provides a kind of processing method of BMS voltage acquisitions failure, including：
S10：Judge whether BMS voltage acquisitions occur exception；
If so, S20 is then executed；
If it is not, then returning S10.
Specifically, always voltage acquisition is monitored in BMS, once voltage acquisition goes wrong, for example, is collected
Voltage data is substantially abnormal or cannot collect voltage data, then it is assumed that BMS voltage acquisitions occur abnormal.For example it can be said that
The battery cell voltage data for typically collecting is between 2.5V～3.65V, according to test data, is manually set normal fair
Perhaps excursion is 2V～5V, if collecting suddenly voltage data for 1V or 6V, can be determined that and occurs for BMS voltage acquisitions
Abnormal, then execute S20.If the data for collecting are constantly in normal permission excursion, S10 is continuously carried out, to electricity
Pressure collection carries out lasting monitor in real time.
S20：Obtain the average current that interior battery output for the previous period occurs in failure；
Wherein, the S20 includes：
S201：The transient current of battery output in record a period of time；
S202：Read the transient current that interior battery output for the previous period occurs in recorded, failure；
S203：The mean value that the transient current of interior battery output for the previous period occurs in failure is calculated, as average current.
Specifically, within a certain period of time, if the load of automobile does not have too big change, the electric current of battery output
It is also metastable.So in the present embodiment, it is assumed that during failure generation, the electric current of battery output is electric before occurring with failure
The electric current of pond output is identical.
For example, when battery operated, BMS is monitored to the electric current that battery is exported always in real time, and when gathering to each
The transient current at quarter is recorded.8：00：When 30, voltage acquisition breaks down, then BMS is just from recorded transient current
Middle reading 8：00：00～8：00：Transient current in 30 time periods, and the transient current in the time period is averaged, then
Average current can be tried to achieve.In the present embodiment, using average current as battery during voltage acquisition failure output current.Yu Ben
In embodiment, the mean value 250A of the electric current of battery output in 30s before failure occurs is obtained as average current.In other enforcements
In example, it is also possible to obtain 8：00：00～8：00：25、8：00：10～8：00：30 or 8：00：00～8：00：In 35 time periods
The mean value of the electric current of battery output is used as average current.
S30：Obtain the first battery remaining power that failure occurs the moment；
Specifically, BMS carries out real-time monitoring to the battery remaining power (State of Charge, i.e. SOC) of battery always
And record, when voltage acquisition module breaks down, then read the data of record, and the remaining battery by the moment that breaks down
Capacity is used as the first battery remaining power.
For example, when voltage acquisition module breaks down, battery remaining power is 10kw h, then the first remaining battery holds
Amount=10kw h.
S40：According to average current, trouble duration and the first battery remaining power, the of current time is calculated
Two battery remaining powers.
Specifically, the second battery remaining power=the first battery remaining power-average current × trouble duration.Its
In, the trouble duration is the absolute value of the difference that current time occurs the moment with failure.
For example, 8：00：At 35 moment, trouble duration is 5s, the second battery remaining power=10000w h-250A
× 5s=10000w h-250 × 5/3600w h=9999.66w h
S50：The ratio of the second battery remaining power and rated cell capacity is calculated, the virtual battery for obtaining current time is remained
Remaining electricity；
Specifically, in the present embodiment, rated cell capacity is 16kw h.Then 8：00：The virtual battery at 35 moment is remaining
Electricity=9999.66w h/16kw h ≈ 0.625=62.5%.
S60：Using virtual battery dump energy, according to the mapping between measured battery dump energy and measured battery voltage
Relation, obtains the virtual battery voltage at current time；
Further, the S60 is specifically included：
S601：SOC is input into battery management system with voltage mapping relations；
S602：Virtual battery dump energy is substituted into the SOC and voltage mapping relations, virtual battery voltage is obtained.
Specifically, when battery works under different dump energies, its voltage be also different, therefore, the residue of battery
There are certain mapping relations between electricity and cell voltage.Accordingly, when the design of battery, production, debugging etc. is carried out, so that it may
To measure the mapping relations between the dump energy of battery and cell voltage, abbreviation SOC and voltage mapping relations.In the present embodiment
In, SOC is made form, referred to as SOC voltmeters with voltage mapping relations.In other embodiments, SOC is closed with voltage mapping
System is expressed as the forms such as curve map or fitting function.
In S50,8 have been tried to achieve：00：The virtual battery dump energy at 35 moment is 54.69%, according to SOC voltmeters
It is recognised that when the dump energy of battery is 54.69%, battery cell voltage is 3.25V, using this as 8：00：35 moment
Virtual battery voltage.
In the present embodiment, before automobile dispatches from the factory i.e. SOC and voltage mapping relations input BMS in stored, when send out
During raw voltage acquisition failure, then SOC and voltage mapping relations are read from BMS, and virtual battery dump energy is substituted into described
SOC and voltage mapping relations, obtain virtual battery voltage.
S70：Using the value of virtual battery voltage as battery management system gathered data.
Specifically, due to cannot collection voltages data, so BMS just can cannot carry out battery management operation.The present embodiment
8 have been tried to achieve in S60:00:The virtual battery voltage at 35 moment is 3.25V, using 3.25V as 8：00：The battery at 35 moment
Voltage is supplied to BMS, then BMS can just continue executing with battery management operation, be not result in that cell power systems disconnect suddenly.
Processing method according to the present embodiment, it is possible to which other moment when occurring for voltage acquisition failure provide virtuality
Cell voltage, and then ensure that BMS continues executing with battery management operation, prevent cell power systems from disconnecting suddenly.
S80：Whether the failure judgement duration reaches the fault time upper limit；
If so, then reporting fault, disconnects cell power systems；
If it is not, then returning S10.
Specifically, the voltage acquisition fault handling method described in the present embodiment can be used for the voltage acquisition event in the short time
Barrier, if voltage acquisition failure occurs in long-time, should disconnect cell power systems, check failure cause.
Further, find through repetition test, the fault time upper limit is set to 8s～12s more suitable, especially will
It is the most suitable that the fault time upper limit is set to 10s.It is arranged such, has both been unlikely to too short-range missile and has caused Consumer's Experience to be deteriorated, be unlikely to again too
Length causes BMS system damages.
